    Las tortugas carey (Eretmochelys imbricata) fueron en una época muy abundantes en el Pacífico Oriental (PO) pero en la actualidad es una de las poblaciones de tortugas marinas más amenazadas a nivel mundial. El Salvador es el país más pequeño de Centroamérica, y posee una alta densidad poblacional lo que ha llevado a la sobreexplotación de muchos de los recursos naturales del país, incluyendo a las especies de tortugas marinas. Donde se considera que aproximadamente el 99% de todos los huevos...

    Full Text Available El Caribe costarricense es importante como sitio de alimentación, copulación, anidación y desove de las tortugas marinas, por lo que el presente trabajo pretendió actualizar el patrón de anidación en las tortugas marinas Dermochelys coriacea y Eretmochelys imbricata en el sector Gandoca, del Refugio Nacional de Vida Silvestre Gandoca Manzanillo, Limón, Costa Rica, para proponer medidas de manejo. Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011, y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525. Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

    The objective of this research was to determine biological and ecological population characteristics of the hawksbill turtle (Eretmochelys imbricata) found in the southern Colombian Pacific Department of Cauca. Morphometric measurements were recorded, the health status of individuals was reviewed, and blood samples were taken for a biochemistry assessment. During the seven months of the investigation, 25 hawksbill turtles were caught (16 different individuals) on the reefs of Gorgona Natural National Park. Forty-six percent of the total numbers of turtles assessed were recaptured during the study period. While no obvious health problems were noted, most animals possessed epibionts and filamentous algae covering the carapace, some parts of the limbs, as well as on their neck. Curved carapace length (CCL) showed the highest proportion of individuals were between 37 and 45 cm. Sixteen individuals captured in Gorgona Natural National Park were compared with 11 individuals captured in the coastal zone of the Department of Cauca. Using the Mann-Whitney U test, a significant difference in CCL was found between these two groups; the animals from Gorgona National Park were larger than those present on the coast of the mainland (Z = -2.59, p = 0.007). Uric acid concentrations were found to be higher than previously referenced values.

    Full Text Available Las tortugas marinas, Eretmochelys imbricata y Caretta caretta se encuentran distribuidas en aguas tropicales del Indo-Pacífico y Atlántico y son consideradas especies importantes dentro del ecosistema. Estas tortugas se han catalogado en peligro crítico ya que han sido explotadas por su caparazón, huevos y carne. Las poblaciones de ambas especies se encuentran en un declive poblacional significativo en el Caribe colombiano. Los estudios genéticos del ADN mitocondrial permiten el apoyo de planes de manejo y conservación. En el presente estudio se estandarizaron las mejores condiciones de la técnica de PCR para la amplificación de 22 fragmentos de 800 pb solapadas en 50 pb del mitogenoma de las tortugas E. imbricata y C. caretta. Se diseñaron oligonucleótidos-primers para la amplificación de estos mitogenomas a partir de secuencias previamente descritas de la tortuga verde Chelonia mydas. Se evaluó la concentración de Mg+2, ADN, oligonucleótidos-primers y la temperatura de anillamiento. La reacción estandarizada de PCR se obtuvo en un volumen final de 25 μl, conteniendo 20-70 ng de DNA, 0,5-1 mM de cada oligonucleótidos-primers, 1,5-3,0 mM de Mg+2, 1 U de Taq polimerasa y 0,2 mM de cada dNTP’s. Los parámetros de amplificación optimizados fueron: desnaturalización inicial de 5 min a 94 °C, seguida por 35 ciclos de 94 °C por 1 min, 37-50 °C por 1 min (de acuerdo a los oligonucleótidos-primers y 72 °C por 1 min. Se obtuvo el 63 % de la secuencia de la tortuga carey y el 68 % de la tortuga cabezona. Estas secuencias presentaron un 99-100 % de identidad con las secuencias previamente reportadas.

    Ovarian follicular development is an essential process in the determination of maturation stages associated with size. This association acquires importance when managing populations of threatened species. We histologically processed 11 prepubescent ovaries, four pubescent ovaries, and one breeding adult ovary with vitellogenic follicles using specific staining techniques to identify the follicular stages of Eretmochelys imbricata. Follicular stages were compared with maturation stages [including straight carapace length (SCL)]. The ovary presented several germinal beds and a lacunar system less histochemically and morphologically heterogeneous than that of crocodiles. During previtellogenesis (four stages), the oocyte grows rapidly due to the strong transcriptional activity of lampbrush chromosomes and numerous nucleoli, and the strong metabolism associated with lipid synthesis. The Stage III ooplasm showed a Sudan positive band. This stage was the most frequent in all ovarian sections and it was independent of maximal follicular stage. Stage IV, more frequent in pubescent and adult ovaries, presented a lipid vacuole-rich ooplasm and a broadening of the zona pellucida and the theca. The vitellogenesis begins with the penetration and accumulation of spherical glycoprotein yolk platelets and chemically neutral lipid droplets which are observed to be mixed, but spatially and chemically segregated. Both the yolk platelets and lipid droplets increase in size, density, and proximity to the periphery of the oocyte due to their coalescence. The SCL of the immature females did not determine the maximal follicular stage nor its frequency in the ovaries. Straight carapace length turned out to be an imprecise measure in identifying the presence of follicular stages in females larger than the minimum legal size limit in Cuba. Consequently, for a national conservation program to be successful, it must emphasize the critically endangered status of E. imbricata, as well as the

    Full Text Available The aim of this study is to investigate the role of plasma level parameters during nesting activity and provide data potentially useful to future studies on the dynamics of reproductive and stress hormones in the most endangered sea turtle species in the world. Plasma parameters in the sea turtles, olive ridley (Lipodochelys oliveacea and hawksbill (Eretmochelys imbricata from Masirah Island, Oman, were analyzed relative to nesting stress. To date, no study has been conducted on plasma parameter levels in sea turtles during nesting. Field observations were conducted under ideal temperature conditions. At the time of sampling, there was no significant difference for cloacal, sand, air or water temperature for the two species. Electrolytes (Cl¯, Ca++, K+, Na+ and Mg++, cholesterol, urea, uric acid and osmolarity were measured during nesting. Both species were observed to spend between 1.5 and 2.00 hours on the nesting grounds. Some had successful oviposition and completed all nesting phases, while others with incomplete nesting phases failed to oviposit their  eggs. Under both conditions, the turtles of both species had an exhaustive and stressful nesting exercise. Plasma parameter values, both intra-specifically and inter-specifically, were not significantly different for oviposited and non-oviposited turtles. This may indicate that both species have the same physiological adjustment relative to plasma parameters whether or not the turtles oviposited their eggs.

    Full Text Available Hybridization among sea turtle species has been widely reported in the Atlantic Ocean, but their detection in the Pacific Ocean is limited to just two individual hybrid turtles, in the northern hemisphere. Herein, we report, for the first time in the southeast Pacific, the presence of a sea turtle hybrid between the green turtle Chelonia mydas and the hawksbill turtle Eretmochelys imbricata. This juvenile sea turtle was captured in northern Peru (4°13′S; 81°10′W on the 5th of January, 2014. The individual exhibited morphological characteristics of C. mydas such as dark green coloration, single pair of pre-frontal scales, four post-orbital scales, and mandibular median ridge, while the presence of two claws in each frontal flipper, and elongated snout resembled the features of E. imbricata. In addition to morphological evidence, we confirmed the hybrid status of this animal using genetic analysis of the mitochondrial gene cytochrome oxidase I, which revealed that the hybrid individual resulted from the cross between a female E. imbricata and a male C. mydas. Our report extends the geographical range of occurrence of hybrid sea turtles in the Pacific Ocean, and is a significant observation of interspecific breeding between one of the world’s most critically endangered populations of sea turtles, the east Pacific E. imbricata, and a relatively healthy population, the east Pacific C. mydas.

    Damazo, Lindsey Renee Eggers

    The hawksbill sea turtle (Eretmochelys imbricata) has a circumtropical distribution and plays an important role in maintaining the health of coral reefs. Unfortunately, hawksbill populations have been decimated, and estimated numbers in the Caribbean are less than 10% of populations a century ago. The hawksbill is considered Critically Endangered, and researchers are coordinating worldwide efforts to protect this species. One country where we lack knowledge regarding hawksbills is Honduras. This study aimed to increase our understanding of hawksbill nesting ecology in Caribbean Honduras. Characteristics of hawksbill nesting activity and a nesting beach on the island of Utila were elucidated using satellite telemetry, beach profiling, vegetation surveys, beach monitoring, and nest temperature profiles. We affixed satellite transmitters to two nesting hawksbills, and found the turtles migrated to different countries. One turtle traveled 403 km to a bay in Mexico, and the other traveled 181 km to a Marine Protected Area off Belize. This study presents the first description of hawksbill migration routes from Honduras, facilitating protection efforts for turtles that traverse international waters. To investigate nesting beach and turtle characteristics, we conducted beach monitoring during the 2012 nesting season. Nesting turtle carapace sizes were similar to worldwide values, but hatchlings were heavier. To measure nest temperatures, we placed thermocouple data loggers in four nests and four pseudo-nests. Data suggested metabolic heating may be maintaining nest temperatures above the pivotal temperature. However, large temperature fluctuations corresponding to rainfall from Hurricane Ernesto (as determined using a time series cross-correlation analysis) make it difficult to predict sex ratios, and underscore the impact stochastic events can have on nest temperatures. We created topographic and substrate profiles of the beach, and found it was 475 m long, yet hawksbills

    Full Text Available ABSTRACT Sea turtle hatchlings, in natural abiotic conditions, emerge from their nests at night and go directly to the sea, following the moonlight’s reflection in the ocean. Increased human activities such as tourism and artificial lights on the coasts, however, have interfered with the ability of sea turtle neonates to find their correct destination, negatively affecting their survival rates. Here we endeavored to assess the influence of artificial lights on the hatchlings of the sea turtle Eretmochelys imbricata (Linnaeus, 1766 in the south coast of the state of Pernambuco, Brazil. To that end, 10 experiments were conducted with 15 hatchlings/test subjects. Five experiments took place in artificially illuminated areas and five in non-illuminated areas. Circles with a 2 m radius were drawn on the sand a small 2-3 cm depression was made at the center of each circles. The neonates were then placed in the depressions to simulate their coming from a nest. After the neonates crossed the edge of the circles, their tracks were photographed and drawn on a diagram. To ascertain if the trajectories of the neonates differed between the two groups (hatchlings from illuminated versus non-illuminated nests, the Rayleigh test was used. The significance of those differences was tested using ANOVA. To evaluate similarities and significance of clusters, a Multi-Dimensional Scaling was used. The tracks of 86.67% (N = 65 of the hatchlings from nests at illuminated areas departed from their correct trajectory. The distribution of trajectories was considered random (V = 19.4895, p > 0.05 only for tracks originating from artificially illuminated areas. The movement patterns of hatchlings from illuminated and non-illuminated areas differed significantly (F < 0.0001, p < 0.01. Consistent with this, two distinct groups were identified, one from illuminated and one from non-illuminated areas. Therefore, we conclude that artificial illumination impacts the orientation

    Chromium is both a global marine pollutant and a known human health hazard. In this study, we compare the cytotoxicity and genotoxicity of both soluble and particulate chromate in human and hawksbill sea turtle (Eretmochelys imbricata) skin fibroblasts. Our data show that both soluble and particulate Cr(VI) induce concentration-dependent increases in cytotoxicity, genotoxicity, and intracellular Cr ion concentrations in both human and hawksbill sea turtle fibroblasts. Based on administered concentration, particulate and soluble Cr(VI) were more cytotoxic and clastogenic to human cells than sea turtle cells. When the analysis was based on the intracellular concentration of Cr, the data showed that the response of both species was similar. The one exception was the cytotoxicity of intracellular Cr ions from soluble Cr(VI), which caused more cytotoxicity in sea turtle cells (LC50=271μM) than that of human cells (LC50=471μM), but its clastogenicity was similar between the two species. Thus, adjusting for differences in uptake indicated that the explanation for the difference in potency was mostly due to uptake rather than differently affected mechanisms. Overall these data indicate that sea turtles may be a useful sentinel for human health responses to marine pollution. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available As tartarugas marinhas compõem o grupo dos répteis mais ameaçados de extinção do mundo, pois além de parâmetros intrínsecos de sua biologia, a influência humana nos sítios de desova é considerada a principal causa da diminuição de suas populações, seja pela caça dos adultos, roubo dos ovos ou influência no processo de desenvolvimento e nascimento dos filhotes, em especial no que se refere a Eretmochelys imbricata, que apresenta seus sítios de reprodução em áreas tropicais com alta frequência humana. Diante do exposto, este trabalho investiga a influência dos diferentes níveis de impacto ambiental na escolha da praia para desova da espécie E. imbricata. A pesquisa foi realizada no município de Ipojuca, litoral sul do estado de Pernambuco, nas praias de Merepe e Porto de Galinhas. Para coleta de dados, foi realizado um levantamento bibliográfico referente as atividades de monitoramento de desovas no litoral, visita as áreas de estudo para observação com realização de fotografias e foi construído um check-list para analisar os parâmetros de impactos antrópicos percebidos na região. Após realizada análise dos dados de acordo com os critérios estabelecidos no check-list, e feito o levantamento do número de desovas nas praias investigadas, comprovou-se que a praia de Porto de Galinhas apresentou os menores registros de desovas de tartarugas e as maiores ações modificadoras sobre o ambiente costeiro. Esse resultado está diretamente ligado a forte especulação imobiliária daquele ambiente praial. Por outro lado, a praia de Merepe possui melhores condições para desovas naquele litoral.

    Full Text Available Habitat bioaugmentation and introduction of protective microbiota have been proposed as potential conservation strategies to rescue endangered mammals and amphibians from emerging diseases. For both strategies, insight into the microbiomes of the endangered species and their habitats is essential. Here, we sampled nests of the endangered sea turtle species Eretmochelys imbricata that were infected with the fungal pathogen Fusarium falciforme. Metagenomic analysis of the bacterial communities associated with the shells of the sea turtle eggs revealed approximately 16,664 operational taxonomic units, with Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes as the most dominant phyla. Subsequent isolation of Actinobacteria from the eggshells led to the identification of several genera (Streptomyces, Amycolaptosis, Micromomospora Plantactinospora and Solwaraspora that inhibit hyphal growth of the pathogen F. falciforme. These bacterial genera constitute a first set of microbial indicators to evaluate the potential role of microbiota in conservation of endangered sea turtle species.

    Data on the impact of environmental pollution on the homeostasis of sea turtles remains scarce, particularly in the Southern Gulf of Mexico. As many municipalities along the coastline of the Yucatan Peninsula do not rely on a waste treatment plant, these organisms could be particularly vulnerable. We searched for relationships between the presence of organochlorine pesticides (OCP) and the level of several oxidative and pollutant stress indicators of the hawksbill sea turtle (Eretmochelys imbricata) during the 2010 nesting season at Punta Xen (Campeche, Mexico). Of the 30 sampled sea turtles, endosulfans, aldrin related (aldrin, endrin, dieldrin, endrin ketone, endrin aldehyde) and dichlorodiphenyldichloroethylene (DDT) families were detected in 17, 21 and 26, respectively. Significant correlation existed between the size of sea turtles with the concentration of methoxychlor, cholinesterase activity in plasma and heptachlors family, and catalase activity and hexachlorohexane family. Cholinesterase activity in washed erythrocytes and lipid peroxidation were positively correlated with glutathione reductase activity. Antioxidant enzyme actions seem adequate as no lipids damages were correlated with any OCPs. Future studies are necessary to evaluate the effect of OCPs on males of the area due to the significant detection of methoxychlor, which target endocrine functioning and increases its concentration with sea turtles size.

    Despite the current environmental concern regarding the risk posed by contamination in marine ecosystems, the concentrations of pollutants in sea turtles have not been thoroughly elucidated. In the current study, we determined the concentrations of 18 organochlorine pesticides (OCPs), 18 polychlorinated biphenyls (PCBs), 16 polycyclic aromatic hydrocarbons (PAHs) and 11 inorganic elements (Cu, Mn, Pb, Zn, Cd, Ni, Cr, As, Al, Hg and Se) for the first time in two sea turtle species (Chelonia mydas and Eretmochelys imbricata). Only five of the 18 analyzed OCPs were detected in both species. The average total OCP concentration was higher in green turtles than in hawksbills (0.33 ng/ml versus 0.20 ng/ml). Higher concentrations of individual congeners and total PCBs were also detected in green turtles than in hawksbills (∑PCBs=0.73ng/ml versus 0.19 ng/ml), and different PCB contamination profiles were observed in these two species. Concerning PAHs, we also observed a different contamination profile and higher levels of contamination in green turtles (∑PAHs=12.06 ng/ml versus 2.95 ng/ml). Di- and tri-cyclic PAHs were predominant in both populations, suggesting a petrogenic origin, rather than urban sources of PAHs. Additionally, all of the samples exhibited detectable levels of the 11 inorganic elements. In this case, we also observed relevant differences between both species. Thus, Zn was the most abundant inorganic element in hawksbills (an essential inorganic element), whereas Ni, a well-known toxicant, was the most abundant inorganic element in green turtles. The presence of contaminants is greater in green turtles relative to hawksbill turtles, suggesting a greater exposure to hazardous chemical contaminants for green turtles. These results provide baseline data for these species that can serve for future monitoring purposes outlined in the EU's Marine Strategy Framework Directive. Copyright © 2014 Elsevier B.V.

    Full Text Available Plasma adrenaline (ADR and noradrenaline (NA levels were measured for the first time in natural populations of hawksbill (Eretmochelys imbricata and olive ridley (Lipedochelys olivacea in Masirah Island, Arabian Sea; one of the few protected nesting grounds remaining in the world for these two endangered species. Plasma ADR and NA levels were assessed in individuals after they oviposited eggs and completed nesting exercises, and in individuals which were still searching for suitable nesting sites. Blood samples were taken from the cervical sinuses from two groups (oviposited and non-oviposited, which spent at least 1.5 h on the nesting grounds. The duration of the nesting period varied between 1.5 and 2.0 h for both species. There was no significant difference between oviposited and non-oviposited turtles in both species. As the turtles move onto the nesting grounds, their heavy weight compresses the thoracic region making terrestrial breathing laborious and difficult. During phases of nesting, the turtles undergo brief bursts of strenuous and exhaustive exercise which usually lasts less than one minute followed by a brief recovery period which is less than the exercise phase. Reptiles in general, particularly turtles, are intermittent breathers and after bursts of exercise, they appear to develop hypoxia, hypercapnia and acidemia, which are characteristic of anaerobic metabolism. The data reveals that catecholamine levels remain stable in both species during phases of nesting and may play an important role in combating stress as well as mobilizing energy reserves. The high plasma lactate and CO2 levels in olive and hawksbill turtles may signify anaerobic metabolism during exercise. Glucose levels remain unchanged throughout nesting in both species. There was no significant difference in the lactate and glucose values in the two species. The physiological and the behavioral adjustments in this study showed remarkable similarities in the two

Gonad maturity is usually evaluated through macroscopic analysis of the gonads. In sea turtles, the maturation stages are associated with body size, depending on the studied marine stock. Fishermen classify turtles bigger than 65.0cm as sexually mature. If they have secondary sex characters they are recorded as breeding males. We compared body size with macroscopic and microscopic gonad characteristics in two Cuban turtles. Eighteen individuals of C. mydas and twenty of E. imbricata was obtained from the legal fishery stock of Jardines del Rey Archipelago (Cuba, from October 2005 and 2006. In males, breeding condition (maximum spermiogenesis was checked by histological analysis of the testes. In females, sexual maturity was identified by the presence of vitellogenic follicles or ovarian corpora. Most males were immature (C. mydas: 79.0cm; E. imbricata: 73.1±4.9cm, n=3 and lacked secondary sex characters. Some E. imbricata without a developed penis were in spermatogenic stages II to IV (i.e. pubescent. Most females were immature (C. mydas: 79.6±7.7cm, n=17; E. imbricata: 69.0±7.1cm, n=16; i.e.prepubescent and pubescent. The prepubescent females had ovaries with previtellogenic follicles near 1.0mm in a compact and yellowish stroma. The pubescent females had ovaries with previtellogenic follicles between 2.0 and 3.0mm. The stroma was more loosened and irrigated than in prepubescent turtles. The finding of spermatogenic activity in pubescent males indicates asynchrony between testicular and penial development in E. imbricata. The current phenotypical approach used by fishermen is not enough to determine sexual maturation in these turtles. The minimal size tentatively should be changed to: C. mydas: above 93.0cm and E. imbricata above 79

Os dados de temperatura foram coletados em nove ninhos, durante os meses de janeiro a junho de 2013, com auxílio de registradores de temperatura do tipo Data loggers (Modelo Onset Computer, UA-001-08. As médias registradas para os ninhos amostrados em relação ao período de incubação e temperatura foram de 54 dias e de 31,68ºC. Com base nesses resultados, os ninhos apresentaram uma forte tendência para o desenvolvimento de fêmeas, sendo a razão sexual, estimada por meio de análises histológicas, de 86,53% para fêmeas. Portanto, a Praia de Merepe possui temperaturas que propiciam uma maior diferenciação de neonatos fêmea.

  5. Congratulations to Carey King

    I first came across Carey King when, out of the blue, he invited me to a special session of the annual meeting of the American Association for the Advancement of Science (the largest and most prestigious US scientific meeting) where he was developing a special session on energy return on investment (EROI). At that meeting and since, I have found Carey to be a refreshing new colleague, extremely intelligent, very knowledgeable about many diverse aspects of energy and other things, able to take criticism and to dish it out, and very ambitious, which is mostly a good thing. He is becoming a leader in thinking about EROI and its implications, and I am delighted to see him honored by Environmental Research Letters. This is important because in the US, there is little insight about energy or, especially, its potential physical limitations except when gas prices increase. There is also little awareness of the very strong historical connection in both the US and the world between increased affluence and increased use of energy, especially petroleum. It is not understood by all that many of the economic problems we have now (such as the budgetary problems faced by most of our State governments, pension plans and universities) have substantial origin in the fact that oil and other energy production no longer increase reliably year after year, as they once did (Murphy and Hall 2011). Many economists have argued in the past that energy is not important because it constituted only 5 per cent or so of GDP, or because they believe that market forces and innovations will substitute for any shortage (e.g. Barnett and Morse 1963, Passell et al 1972, Solow 1974, Denison 1989). One problem with that view is that if you remove that five per cent the economy comes to a dead stop, as Cuba found out in 1989 when Russia removed its oil subsidy. Additionally if that five per cent goes up to 10 or 15 per cent, as it did in the early 1980s, and again in 2008, recession steps in (Murphy and

    Full Text Available Understanding the connections between sea turtle populations is fundamental for their effective conservation. Brazil hosts important hawksbill feeding areas, but few studies have focused on how they connect with nesting populations in the Atlantic. Here, we (1 characterized mitochondrial DNA control region haplotypes of immature hawksbills feeding along the coast of Brazil (five areas ranging from equatorial to temperate latitudes, 157 skin samples, (2 analyzed genetic structure among Atlantic hawksbill feeding populations, and (3 inferred natal origins of hawksbills in Brazilian waters using genetic, oceanographic, and population size information. We report ten haplotypes for the sampled Brazilian sites, most of which were previously observed at other Atlantic feeding grounds and rookeries. Genetic profiles of Brazilian feeding areas were significantly different from those in other regions (Caribbean and Africa, and a significant structure was observed between Brazilian feeding grounds grouped into areas influenced by the South Equatorial/North Brazil Current and those influenced by the Brazil Current. Our genetic analysis estimates that the studied Brazilian feeding aggregations are mostly composed of animals originating from the domestic rookeries Bahia and Pipa, but some contributions from African and Caribbean rookeries were also observed. Oceanographic data corroborated the local origins, but showed higher connection with West Africa and none with the Caribbean. High correlation was observed between origins estimated through genetics/rookery size and oceanographic/rookery size data, demonstrating that ocean currents and population sizes influence haplotype distribution of Brazil's hawksbill populations. The information presented here highlights the importance of national conservation strategies and international cooperation for the recovery of endangered hawksbill turtle populations.

    Surveys of juvenile hawksbills around Buck Island Reef National Monument, US Virgin Islands from 1994 to 1999 revealed distributional patterns and resulted in a total of 75 individual hawksbill captures from all years; turtles ranged from 23.2 to 77.7 cm curved carapace length (CCL; mean 42.1 ± 12.3 cm SD). Juveniles concentrated where Zoanthid cover was highest. Length of time between recaptures, or presumed minimum site residency, ranged from 59 to 1,396 days (mean 620.8 ± 402.4 days SD). Growth rates for 23 juveniles ranged from 0.0 to 9.5 cm year−1 (mean 4.1 ± 2.4 cm year−1SD). Annual mean growth rates were non-monotonic, with the largest mean growth rate occurring in the 30–39 cm CCL size class. Gastric lavages indicated that Zoanthids were the primary food source for hawksbills. These results contribute to our understanding of juvenile hawksbill ecology and serve as a baseline for future studies or inventories of hawksbills in the Caribbean.

    Concentrations of total arsenic (As) and individual compounds were determined in green and hawksbill turtles from Ishigaki Island, Japan. In both species, total As concentrations were highest in muscle among the tissues. Arsenobetaine was a major compound in most tissues of both turtles. High concentrations of trimethylarsine oxide were detected in hawksbill turtles. A significant negative correlation between standard carapace length (SCL), an indicator of age, and total As levels in green turtles was found. In contrast, the levels increased with SCL of hawksbill turtles. Shifts in feeding habitats with growth may account for such a growth-dependent accumulation of As. Although concentrations of As in marine sponges, the major food of hawksbill turtles are not high compared to those in algae eaten by green turtles, As concentrations in hawksbill turtles were higher than those in green turtles, indicating that hawksbill turtles may have a specific accumulation mechanism for As. - Green turtles and hawksbill turtles have specific accumulation features of arsenic

    Chromium is both a global marine pollutant and a known human health hazard. In this study, we compare the cytotoxicity and genotoxicity of both soluble and particulate chromate in human and hawksbill sea turtle (Eretmochelys imbricata) skin fibroblasts. Our data show that both soluble and particulate Cr(VI) induce concentration-dependent increases in cytotoxicity, genotoxicity, and intracellular Cr ion concentrations in both human and hawksbill sea turtle fibroblasts. Based on administered concentration, particulate and soluble Cr(VI) were more cytotoxic and clastogenic to human cells than sea turtle cells. When the analysis was based on the intracellular concentration of Cr, the data showed the response of both species was similar. The one exception was the cytotoxicity of intracellular Cr ions from soluble Cr(VI), which caused more cytotoxicity in sea turtle cells (LC50=271 uM) that human cells (LC50=471 uM), but its clastogenicity was similar between the two species. Thus, adjusting for differences in uptake indicated the explanation for the difference in potency was mostly due to uptake rather than differently affected mechanisms. Overall these data indicate sea turtles may be a useful sentinel for human health responses to marine pollution. PMID:26440299

    In August 2002, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Carey Creek property, an acquisition completed by the Kalispel Tribe of Indians in December 2001. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Carey Creek Project provides a total of 172.95 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 4.91 HUs for bald eagle, black-capped chickadee, and white-tailed deer. Forested wetlands provide 52.68 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Scrub-shrub wetlands provide 2.82 HUs for mallard, yellow warbler and white-tailed deer. Wet meadow and grassland meadow provide 98.13 HUs for mallard and Canada goose. Emergent wetlands provide 11.53 HUs for mallard, muskrat, and Canada goose. Open water provides 2.88 HUs for Canada goose, mallard, and muskrat. The objective of using HEP at the Carey Creek Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

    Organochlorine pesticides and PCB (POPs) concentrations were determined in the blood and eggs of green and hawksbill turtles. We compared concentrations between species, analyzed the relationship between turtle size and the POPs concentrations and the relationship between the concentrations in the blood of the nesting turtles and their eggs. We expected higher concentrations in the hawksbill turtle because of its higher trophic level, but concentrations were not higher in all the cases. Significant differences were found in δ-HCH blood concentrations. Lindane, heptachlor epoxide and PCB 101 concentrations were significantly higher in the hawksbill eggs. The relationship between the size of the turtles and the POP concentrations in the eggs of the hawksbills showed a negative correlation. No correlation was found between the size of the female and concentrations in the blood. In eggs, only the hawksbill turtles exhibited negative correlation in the concentration of mirex and PCB 44 and size. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Microbial groups are major factors that influence soil function. Currently, there is a lack of studies on microbial functional groups. Although soil microorganisms play an important role in the nitrogen cycle, systematic studies of the effects of environmental factors on microbial populations in relation to key metabolic processes in the nitrogen cycle are seldom reported. In this study, we conducted a systematic analysis of the changes in nitrogen functional groups in mandarin orange garden soil treated with Azolla imbricata. The structures of the major functional bacterial groups and the functional gene abundances involved in key processes of the soil nitrogen cycle were analyzed using high-throughput sequencing (HTS) and quantitative real-time PCR, respectively. The results indicated that returning A. imbricata had an important influence on the composition of soil nitrogen functional bacterial communities. Treatment with A. imbricata increased the diversity of the nitrogen functional bacteria. The abundances of nitrogen functional genes were significantly higher in the treated soil compared with the control soil. Both the diversity of the major nitrogen functional bacteria (nifH bacteria, nirK bacteria, and narG bacteria) and the abundances of nitrogen functional genes in the soil showed significant positive correlations with the soil pH, the organic carbon content, available nitrogen, available phosphorus, and NH 4 + -N and NO 3 - -N contents. Treatment with 12.5 kg fresh A. imbricata per mandarin orange tree was effective to improve the quality of the mandarin orange garden soil. This study analyzed the mechanism of the changes in functional bacterial groups and genes involved in key metabolic processes of the nitrogen cycle in soil treated by A. imbricata.

    Full Text Available Fire is a critical disturbance in the structuring and functioning of most Mediterranean ecosystems. In northwestern Patagonia, vegetation patterns are strongly influenced by fire and environmental heterogeneity. Dendroecology, together with satellite imagery and GIS, have been demonstrated to be useful tools in studies that relate to fire effects with patches, patterns and species dynamics at landscape scale. Such studies can be approached from landscape ecology, which has evolved in the last years supported by the development of remote sensing and GIS technologies. This study evaluates the spatial dynamic of F. imbricata in response to fire using remote sensing, GIS and dendrochronology techniques, at landscape scale. Two sites were evaluated and one of them was affected by fire in the year 1999. The digital processing images (using the NBR spectral index and the dendroecological analysis verified this. A fire, occurring in 1978, was also detected by the analysis of F. imbricata growth rings. The relation between F. imbricata shrubland dynamics and spatial configuration with fire, land topography and hydrography was established in the study area.

    It is generally accepted that progesterone is necessary to maintain gestation; however, the mechanisms that control the production of this steroid remain unknown. The corpus luteum has been assigned a central role in the maintenance of gestation based on its capacity to produce progesterone. A pseudopregnancy model was performed in a viviparous lizard, Barisia imbricata imbricata, to determine whether the absence of embryos would affect the pattern of progesterone production or the corpus luteum histology. Blood samples were obtained prior to ovulation and at 8, 16, and 24 weeks after ovulation (pseudopregnant and pregnant lizards), as well as one day after parturition (pregnant lizards) or 32 weeks after ovulation (pseudopregnant lizards). The corpus luteum was surgically removed one day after blood samples were obtained. Blood aliquots from nongravid females were obtained at similar timepoints. We found a significant reduction in plasma progesterone concentrations at 24 and 32 weeks post-ovulation in pseudopregnant lizards compared with those observed at similar times in intact pregnant lizards, whereas the progesterone levels in non-gestant lizards remained significantly lower than in either pseudopregnant or pregnant lizards. Moreover, we observed that the histological appearance of the corpus luteum from pseudogestational females (obtained 24 and 32 weeks post-ovulation) differed from the corpora lutea from lizards in late gestation and intact parturient lizards. These observations suggest that the conceptus participates in the regulation of progesterone production in late gestation and also in luteolysis control. Copyright © 2014 Elsevier B.V.

    Full Text Available Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabilitation attempt to restore the endangered mangroves on Carey Island, Malaysia. A submerged detached breakwater system was constructed to dampen the energy of wave and trap the sediments behind the structure. Further, a large number of mangrove seedlings were planted using different techniques. Further, we assess the possibility of success for a future mangrove rehabilitation project at the site in the context of sedimentology, bathymetry, and hydrogeochemistry. The assessment showed an increase in the amount of silt and clay, and the seabed was noticeably elevated. The nutrient concentration, the pH value, and the salinity index demonstrate that the site is conducive in establishing mangrove seedlings. As a result, we conclude that the site is now ready for attempts to rehabilitate the lost mangrove forest.

    The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene. Most often is a true ankylosis of the TMJ but other pathological mechanisms are described (i.e., the fusion of the coronoid process to temporal bone or with the zygoma, or a variety of soft tissues disorders like Fibrodysplasia Ossificans Progressiva). Here we report a 2-year-old girl fitting with a clinical diagnosis of CFZS associated with a limited mouth opening in which temporomandibular joint ankylosis was suspected. Because it has been postulated that many clinical features in CFZS may only be secondary effects of brainstem anomalies and muscle weakness during development, the limited opening of the mouth observed in our patient could represent a rare clinical feature of CFZS itself. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

(Rose root or Arctic root or Golden root or Shrolo, belonging to the family Crassulaceae, is an important food crop and medicinal plant in the Indian trans-Himalayan cold desert. Chemometric profile of the n-hexane, chloroform, dichloroethane, ethyl acetate, methanol, and 60% ethanol root extracts of R. imbricata were performed by hyphenated gas chromatography mass spectrometry (GC/MS technique. GC/MS analysis was carried out using Thermo Finnigan PolarisQ Ion Trap GC/MS MS system comprising of an AS2000 liquid autosampler. Interpretation on mass spectrum of GC/MS was done using the NIST/EPA/NIH Mass Spectral Database, with NIST MS search program v.2.0g. Chemometric profile of root extracts revealed the presence of 63 phyto-chemotypes, among them, 1-pentacosanol; stigmast-5-en-3-ol, (3β,24S; 1-teracosanol; 1-henteracontanol; 17-pentatriacontene; 13-tetradecen-1-ol acetate; methyl tri-butyl ammonium chloride; bis(2-ethylhexyl phthalate; 7,8-dimethylbenzocyclooctene; ethyl linoleate; 3-methoxy-5-methylphenol; hexadecanoic acid; camphor; 1,3-dimethoxybenzene; thujone; 1,3-benzenediol, 5-pentadecyl; benzenemethanol, 3-hydroxy, 5-methoxy; cholest-4-ene-3,6-dione; dodecanoic acid, 3-hydroxy; octadecane, 1-chloro; ethanone, 1-(4-hydroxyphenyl; α-tocopherol; ascaridole; campesterol; 1-dotriacontane; heptadecane, 9-hexyl were found to be present in major amount. Eventually, in the present study we have found phytosterols, terpenoids, fatty acids, fatty acid esters, alkyl halides, phenols, alcohols, ethers, alkanes, and alkenes as the major group of phyto-chemotypes in the different root extracts of R. imbricata. All these compounds identified by GC/MS analysis were further investigated for their biological activities and it was found that they possess a diverse range of positive pharmacological actions. In future, isolation of individual phyto-chemotypes and subjecting them to biological activity will definitely prove fruitful

    Although the events of spermiogenesis are commonly studied in amniotes, the amount of research available for Squamata is lacking. Many studies have described the morphological characteristics of mature spermatozoa in squamates, but few detail the ultrastructural changes that occur during spermiogenesis. This study's purpose is to gain a better understanding of the subcellular events of spermatid development within the Imbricate Alligator Lizard, Barisia imbricata. The morphological data presented here represent the first complete ultrastructural study of spermiogenesis within the family Anguidae. Samples of testes from four specimens collected on the northwest side of the Nevado de Toluca, México, were prepared using standard techniques for transmission electron microscopy. Many of the ultrastructural changes occurring during spermiogenesis within B. imbricata are similar to that of other squamates (i.e., early acrosome formation, chromatin condensation, flagella formation, annulus present, and a prominent manchette). However, there are a few unique characteristics within B. imbricata spermatids that to date have not been described during spermiogenesis in other squamates. For example, penetration of the acrosomal granule into the subacrosomal space to form the basal plate of the perforatorium during round spermatid development, the clover-shaped morphology of the developing nuclear fossa of the flagellum, and the bulbous shape to the perforatorium are all unique to the Imbricate Alligator Lizard. These anatomical character differences may be valuable nontraditional data that along with more traditional matrices (such as DNA sequences and gross morphological data) may help elucidate phylogenetic relationships, which are historically considered controversial within Squamata.

    2018-01-01

    Under conditions of Azolla imbricata restoration, the high-throughput sequencing technology was employed to determine change trends of microbial community structures in the soil that had undergone long-term application of pesticides. The relationship between the content of pesticide residues in the soil and the microbial community structure was analyzed. The results indicated that the microbial diversity was strongly negatively correlated with the contents of pesticide residues in the soil. At a suitable dosage of 5 kg fresh A. imbricata per square meter of soil area, the soil microbial diversity increased by 12.0%, and the contents of pesticide residues decreased by 26.8-72.1%. Sphingobacterium, Sphingopyxis, Thermincola, Sphingobium, Acaryochloris, Megasphaera, Ralstonia, Pseudobutyrivibrio, Desulfitobacterium, Nostoc, Oscillochloris, and Aciditerrimonas may play major roles in the degradation of pesticide residues.

    Despite increased worldwide popularity of keeping reptiles as pets, we know little about hematologic and biochemical parameters of most reptile species, or how these measures may be influenced by intrinsic and extrinsic factors. Blood samples from 43 wild-caught pythons (Morelia spilota imbricata) were collected at various stages of a 3-yr ecological study in Western Australia. Reference intervals are reported for 35 individuals sampled at the commencement of the study. As pythons were radiotracked for varying lengths of time (radiotransmitters were surgically implanted), repeated sampling was undertaken from some individuals. However, because of our ad hoc sampling design we cannot be definitive about temporal factors that were most important or that exclusively influenced blood parameters. There was no significant effect of sex or the presence of a hemogregarine parasite on blood parameters. Erythrocyte measures were highest for pythons captured in the jarrah forest and at the stage of radiotransmitter implantation, which was also linked with shorter time in captivity. Basophil count, the only leukocyte influenced by the factors tested, was highest when the python was anesthetized, as was globulin concentration. Albumin and the albumin:globulin ratio were more concentrated in summer (as was phosphorous) and at the initial stage of radiotransmitter placement (as was calcium). No intrinsic or extrinsic factors influenced creatinine kinase, aspartate aminotransferase, uric acid, or total protein. This study demonstrates that factors including season, location, surgical radiotransmitter placement, and anesthetic state can influence blood parameters of M. s. imbricata. For accurate diagnosis, veterinarians should be aware that the current reference intervals used to identify the health status of individuals for this species are outdated and the interpretation and an understanding of the influence of intrinsic and extrinsic factors are limited.

Essa viagem foi o primeiro trabalho de campo para a minha tese em Geografia e Gestão Ambiental (em andamento. Essa edição da experimentação visava propiciar a um grupo de gestores franceses, participantes de um seminário de cunho terapêutico chamado “Descobrir-se em terras desconhecidas”, a oportunidade de viver alguns dias em condições materiais rudimentares em uma natureza inóspita, convivendo com comunidades locais. A experiência incluiu: travessias em catraias, trechos em botes infláveis, viagens de camionete em rodovias perigosas, e o melhor: longos trechos de rio a bordo do barco Peixe – Boi, que se tornaria nosso hotel, meio de transporte, refeitório e palco de intensas sessões do seminário Se découvrir en terres inconnues. De forma geral a experimentação mostrou resultado positivo. Concluí que o turismo de base comunitária, da forma como foi realizado no Parque Nacional do Cabo Orange, teve dois efeitos principais: a experiência singular de conviver com comunidades ribeirinhas e o  aprofundamento das relações entre o parque nacional e o seu entorno. Ao final, anexei trechos de entrevistas realizadas com moradores de comunidades ribeirinhas vizinhas do parque nacional e também de um documento raro encontrado nesta viagem: um levantamento sócio-cultural de uma das comunidades, realizado por professores de História e alunos da escola da Vila Velha do Cassiporé.En novembre 2009, j’ai participé, pendant neuf jours, à un projet appelé “Projet de tourisme à base communautaire Tartaruga Imbricata”, un parcours intégré entre le Parc National Cabo Orange au Brésil et la Guyane française.

    2012-12-01

    Full Text Available In his latest novel Parrot and Olivier in America (2009 the Australian-born novelist Peter Carey explores the way three seemingly incompatible civilisations translate the New World. On the one hand Olivier, the snobbish French aristocrat, struggles to understand the concept of democracy in America because he wants to translate it ‘literally’ into his own system (of behaviour, social convenience, pragmatics, etc.. On the other hand, Parrot, the British-Australian pícaro and Olivier’s “clown and secretaire”, enjoys rewriting his master’s awful calligraphy, changing some of the Frenchman’s views on America according to his whim, and deliberately acting as a bad translator. Thirdly, the American free citizen, the “Man of the Future” (p. 187: s/he uses language creatively, coining a personal idiolect as evidence of belonging to a nation at its début, where “greed might tear the land apart but still the low could climb so high” (p. 251. This paper aims at illustrating how these three entities translate other systems of values, or their loss of values, into systems with which they can identify. The theoretical framework of my study proceeds from the contributions of Yuri Lotman, the main representative of the Tartu-Moscow school of semiotics.

    Black-shouldered Kite ( Elanus caeruleus ) is a well-known raptor that inhabits open areas such as oil palm plantation or paddy field. To determine preferable habitat and nesting site of Black-shouldered Kite in oil palm landscape, we conducted a study on Black-shouldered Kite's nesting biology in Carey Island, Selangor, Malaysia. We divided the island into six types of habitat and conducted road-side count of Black-shouldered Kite from April 2009 to February 2011. Whenever the Black-shouldered Kite was detected, we thoroughly searched the surrounding area for their nest. In total, we have recorded forty nests. The nests were built on 15 species of trees but most of the trees shared common physical characteristics. Some novice breeders also used oil palm tree as their nesting site. Structure and building materials of nests constructed on oil palm trees were different from nests built on other trees. Of all breeding attempts, only four nests which were located in residential area adjacent to young oil palm habitat were successful. Among important characteristics of successful nesting site include taller trees with strong branches and good leaf coverage. These trees not only protect nests from predator detection (except from other predatory birds) and physical environment but also facilitate Black-shouldered Kite's foraging activities by providing good vantage point.

    Nypa fructicans is a major species of mangrove palm on Carey Island, Malaysia. The main objective of this study is to determine the effects of water properties on the growth of Nypa fruticans. Plant growth measurements and water analyses were carried out in six plots for 16 months. The life stages of Nypa fruticans were divided into seedlings, juveniles, adults and matures, based on the number of leaves. Leaf production of juvenile and mature trees showed negative correlation with salinity. Leaf production of seedlings was affected negatively only by heavy metal of Arsenic (As). Calcium (Ca) in the water had a strong positive effect on the new leaf production of juveniles and on the spear elongation of matures, and Iron (Fe) had a negative effect on the leaf elongation of adults. Similarly, spear elongation of juvenile trees was positively correlated to nitrate (NO3-). Silty clay texture provides the best condition for the growth of Nypa fruticans. The growth of Nypa fruticans was most significantly affected by water parameters in the early life stages. (author)

    This study was designed to examine the effects of cadmium on several color-related parameters (including chlorophyll, carotenoid, and anthocyanin), total phenolics, and phenylalanine ammonia-lyase (PAL) activity in an aquatic fern species Azolla imbricate (A. imbricata). Cd accumulation and effects in the fronds were closely related with Cd concentration in the growth medium. The fronds under 0.5 mg/L Cd treatment turned red on the 3rd day, and this color change also appeared under 0.05 and 0.1 mg/L Cd treatment on the 5th day. Correlated with the color change, the contents of chlorophyll and carotenoid in the fronds significantly decreased in the presence of high Cd concentrations, while the anthocyanin content increased during the experiment. Significant increase in total phenolics content and PAL activity were also detected during Cd treatment. The results suggested that the Cd-induced change in color of fronds might be due to the decrease in chlorophyll and carotenoid and the increase in anthocyanin.

    Full Text Available In 2001, the State Library of Victoria in Melbourne built on its holdings of Australian literary manuscripts by acquiring all the papers, drafts and other items associated with Peter Carey’s Booker Prize-winning novel, True History of the Kelly Gang. The centrepiece of this acquisition, and the focus of this article, is Carey’s Apple Mac Classic laptop computer. The argument that is developed in this article is that Carey’s laptop is a technological artefact that operates, especially at the time of its acquisition, as an important talisman in three interrelated senses. First, it was viewed by library staff as a key means of gaining access to the ‘true history’ of Carey’s own creative drive or creative unconscious. Second, its public display alongside other textual objects (mostly books served to reinforce a reconstructed corporate image that endeavoured to reposition the library as a vital contemporary cultural site and key player in Melbourne’s institutional gallery scene. Third, it was a crucial symbolic acquisition insofar as it spoke to certain desires within library management at that time, and which responded to similar moves at major libraries elsewhere around the world, to embrace collection digitisation as the path forward.

    Full Text Available Indonesian waters have six types of turtles that can live, spawn and breed. Sea turtle conservation becomes an important and urgent program to be done in order to protect and save sea turtle population in Indonesia. One of the factors that most affect the turtle population is the cause of degradation of pathogenic factors. Alas Purwo National Park, East Java, there is some communities that have activities turtle conservation. Conservation is done by securing and protecting turtle eggs. Turtle eggs that have hatched are released into the sea once it is ready. This study aims was to determine the type of bacteria and fungi that infect hatchlings and environmental factors that influence. This research is descriptive method to Hawksbill turtle (Eretmochelys imbricate is by way of random sampling. Sampling of microbes in sea turtle was conducted using cotton swab method and then microbes was cultured and indentified in laboratory. The results showed The kind of parasites and microbes which were indentified in hatching and adult Hawksbill sea turtles were fungus with genus Aspergillus sp., Geotrichum sp., Fusarium sp., and Gliocladium sp. ; bacteria are Pseudomonas aeruginosa and Enterobacter cloaceae; and parasite is Chelonibia testudinaria barnacles.  The parameter average value of water in pond indicated 28.1 – 29.2°C for temperature, 32 - 34 ‰ for salinity, 7.78 – 8.2 for pH, and 3.86 – 4.21 mg/L for DO.

    Landscapes are dynamic in space and time, being spatio-temporal processes of particular interest for landscape ecology. In particular, grasslands can change their structure through the expansion of shrubs in the landscape matrix. Shrub encroachment affect biodiversity as well as forage availability that is the key component of the productive use of rangelands. However, despite its recognition as a global problem, knowledge on the rates, dynamics and encroachment patterns is even scarce. For example, although it is generally accepted that fire control shrub encroachment, certain shrubby species could be favored by the occurrence of fire. In northwestern Patagonian steppe, Fabiana imbricata form large monospecific shrublands that are part of the landscape mosaic and its dynamics of regeneration is strongly related to fire. This long-lived shrub (≡ 150 years) is a typical seeder that is killed by fire and recruits seedlings almost exclusively in post-fire, establishing even-age patches. Our objective was to determine whether F. imbricata shrublands have expanded during the last 40 years in a landscape fire prone. The study area corresponds to San Ramon ranch (22,000 ha) located in northwestern Patagonia steppe, Argentina (latitude -41° 04'; longitude -70° 51'). Two distribution maps of the species were made that corresponds to the study area in 1968 and 2011. The 1968 map was elaborated from the digitalization of aerial photographs (1:45000) while the 2011 map was produced with very high resolution satellite images, current aerial photographs and GPS field data. Both maps were loaded into a GIS environment, in which landscape metrics at patch and class level were determined and then compared. From remote sensing and dendroecological techniques, we know that the study area was almost entirely affected by fires during the study period. Therefore, the comparison of both maps allows us to know post-fire changes in the shrublands spatial configuration at the landscape

    Full Text Available Reported researches dealing with either composition or bioactivity of Salsola imbricata are limited. This study was conducted aiming to investigate the phenolic composition of the plant and evaluate its efficacy as male contraceptive. Polyphenols, namely, phenolic acids and flavonoids, were qualitatively and quantitatively analysed by RP-HPLC in the hydrolysed methanol extract using two different wavelengths, 280 and 330 nm. The efficiency of different solvents in extracting the plant phenolics was assessed via spectrophotometric determination of the total phenolic and flavonoid contents. Acute toxicity study was carried out on the ethanolic extract to ascertain its safety prior to biological evaluation. The contraceptive effect was assessed, in male rats, by oral administration of the extract at two doses (250 and 500 mg/kg b. wt., over a period of 65 days. HPLC analyses allowed the identification and quantification of a total of 13 and 8 components in the hydrolysed-methanol extract; the overall phenolic composition was dominated by quercitrin (12.692% followed by coumaric acid (4.251%. Prolonged oral administration of the ethanolic extract caused slight reduction in the testis weight only. A significant decrease in the sperm count was observed (P<0.01 in the two treated groups while significant decrease in the epididymal sperm motility was only observed in the high dose group. Morphological abnormalities were observed in sperms of treated animals. No distinct change in serum FSH, LH, and testosterone concentration was recorded. The histopathological findings supported to a high extent these results. The male contraceptive activity of Salsola imbricata could be ascribed to its phenolic components, especially quercitrin.

    The present study reports the radioprotective properties of a hydro-alcoholic rhizome extract of Rhodiola imbricata (code named REC-7004), a plant native to the high-altitude Himalayas. The radioprotective effect, along with its relevant superoxide ion scavenging, metal chelation, antioxidant, anti-lipid peroxidation and anti-hemolytic activities was evaluated under both in vitro and in vivo conditions. Chemical analysis showed the presence of high content of polyphenolics (0.971 +/- 0.01 mg% of quercetin). Absorption spectra analysis revealed constituents that absorb in the range of 220-290 nm, while high-performance liquid chromatography (HPLC) analysis confirmed the presence of four major peaks with retention times of 4.780, 5.767, 6.397 and 7.577 min. REC-7004 was found to lower lipid oxidation significantly (p degradation within first 24 h. The metal chelation activity of REC-7004 was found to increase concomitantly from 1 to 50 microg/ml. REC-7004 (10-50 microg/ml) exhibited significant metal chelation activity (p < 0.05), as compared to control, and maximum percentage inhibition (30%) of formation of iron-2,2'-bi-pyridyl complex was observed at 50 microg/ml, which correlated well with quercetin (34.9%), taken as standard. The reducing power of REC-7004 increased in a dose-dependent manner. The absorption unit value of REC-7004 was significantly lower (0.0183 +/- 0.0033) as compared to butylated hydroxy toluene, a standard antioxidant (0.230 +/- 0.091), confirming its high reducing ability. Superoxide ion scavenging ability of REC-7004 exhibited a dose-dependent increase (1-100 microg/ml) and was significantly higher (p < 0.05) than that of quercetin at lower concentrations (1-10 microg/ml), while at 100 microg/ml, both quercetin and REC-7004 scavenged over 90% superoxide anions. MTT assay in U87 cell line revealed an increase in percent survival of cells at doses between 25 and 125 microg/ml in case of drug + radiation group. In vivo evaluation of radio

    Full Text Available Se analizó el crecimiento, la distribución de tallas y la mortalidad de una población de Pinctada imbricata en Guamachito, Península de Araya, Venezuela, entre enero y diciembre de 2000. Los muestreos se realizaron mensualmente sobre transeptos perpendiculares a la línea de la costa con una rastra artesanal, tomando también datos sobre temperatura, oxígeno disuelto y salinidad de la columna de agua. La distribución de tallas fue variable con un predominio de tallas entre 50 y 70 mm, que constituyeron el 75% de la población. La mayor cantidad de juveniles fue observada en marzo, cuando la longitud media en la población fue de 55.8 mm. Los promedios de los pesos húmedo y seco siguieron la misma tendencia, con valores mínimos en junio, julio, septiembre y octubre de 2000. Las relaciones longitud-peso húmedo y longitud-peso seco fueron altamente significativas (P < 0.05. Los parámetros de la ecuación de crecimiento estacionalizada de von Bertalanffy fueron L∞ = 85.15 mm; K = 1.42 año–1, ts = 0.2, y C = 0.20; indicando un crecimiento lento (WP = 0.42 en el periodo de julio a noviembre, asociado con los parámetros ambientales del área con una longevidad estimada en 3 años. La mortalidad total fue de 14.35 año para los individuos pequeños (10–36 mm y 3.45 año, para los individuos grandes (36–84 mm. La alta tasa de crecimiento de P. imbricata muestra ser una ventaja para considerarla como una especie con potencial para actividades de acuicultura en la región. El banco ostrícola presenta buenas condiciones para mantener una explotación pesquera sostenida, tomando en consideración parámetros pesqueros como la captura registrada, el esfuerzo óptimo, la talla mínima de extracción, la mortalidad por pesca y la mortalidad natural.

    A rapid method was developed to determine both types of vitamins in Rhodiola imbricata root for the accurate quantification of free vitamin forms. Rapid resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS) with electrospray ionization (ESI) source operating in multiple reactions monitoring (MRM) mode was optimized for the sequential analysis of nine water-soluble vitamins (B1, B2, two B3 vitamins, B5, B6, B7, B9, and B12) and six fat-soluble vitamins (A, E, D2, D3, K1, and K2). Both types of vitamins were separated by ion-suppression reversed-phase liquid chromatography with gradient elution within 30 min and detected in positive ion mode. Deviations in the intra- and inter-day precision were always below 0.6% and 0.3% for recoveries and retention time. Intra- and inter-day relative standard deviation (RSD) values of retention time for water- and fat-soluble vitamin were ranged between 0.02-0.20% and 0.01-0.15%, respectively. The mean recoveries were ranged between 88.95 and 107.07%. Sensitivity and specificity of this method allowed the limits of detection (LOD) and limits of quantitation (LOQ) of the analytes at ppb levels. The linear range was achieved for fat- and water-soluble vitamins at 100-1000 ppb and 10-100 ppb. Vitamin B-complex and vitamin E were detected as the principle vitamins in the root of this adaptogen which would be of great interest to develop novel foods from the Indian trans-Himalaya.

    Full Text Available ABSTRACT The present work aimed to report the histopathological findings verified in lungs of hawksbill turtles (Eretmochelys imbricata retrieved from the coasts of the states of Espírito Santo and Rio de Janeiro, Brazil. Between the years 2010 and 2014, 29 E. imbricata individuals were found stranded on the coasts, already dead or dying during treatment. Lung samples of all specimens were collected during necropsies, fixed in 10% neutral buffered formalin, subjected to routine histological processing and classified histomorphologically. The findings revealed that 37.93% of the specimens presented lung lesions. Of these, 90.91% were rescued alive and 9.09% were found dead; 63.63% were females and 36.37% were males. The mean weight was 5.44 Kg and the mean length 39 cm, characterizing young individuals. The animals originated from São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES, and Anchieta - ES. Macroscopic analysis revealed presence of foam, hyperemia, nodules in the parenchyma, cyst and caseous material. Microscopic examination evidenced heterophilic bronchopneumonia, parasitic granulomatous pneumonia caused by spirorchiids, bacterial granulomatous pneumonia, fungal granulomatous pneumonia, and congestion. It was concluded that juvenile specimens of Eretmochelys imbricata, females and males, originated from the states of Espírito Santo and Rio de Janeiro and found stranded both alive or dead, have significant lung lesions, mainly inflammatory ones, associated or not with infectious agents.

Some parameters in juveniles are compared with those of adult populations in Colombia and other nesting areas. Caretta and Eretmochelys increased carapax length 9 times, reaching about 40 cm. The ratio of carapax length versus width of 1.3 seems tobe tipical in juveniles and adults of the three observed genera. There are considerable individual variations of size and weight.

    Full Text Available Sustainable tourism emphasises responsible utilisation of economic, socio-cultural and environmental resources for tourism development. Extant literature in sustainable tourism leans towards subjective and qualitative description in explaining the dynamic nature of the trans-disciplinary indicators of sustainability. However, few mechanisms have been proposed or developed to quantify the indicators measuring sustainable tourism in an indigenous ethnic context. The current study measures 61 sustainable indigenous tourism indicators of the Mah Meri ethnic group that comprise three constructs, namely, community resources, community development and sustainable tourism. Simple random sampling was employed for data elicitation and a weighted average score using R software as the basis of analysis was used to produce a sustainable indigenous tourism barometer (SITB. The study identifies 11 sustainability dimensions from the initial three main constructs that are treated as the relationship aspects in this study. Based on the Sustainable Indigenous Tourism Barometer (SITB, community participation, empowerment, economic and socio-cultural sustainability are found to be the main influencing dimensions of sustainability of the Mah Meri ethnic group. However, natural resources, financial resources and environmental sustainability indicated weaker relationships in explaining sustainability of the Mah Meri ethnic group. Based on the SITB, the results demonstrate that the Mah Meri ethnic group are a “potential sustainable” tourism stakeholder.

    Full Text Available Contemporary anxieties around cloning and genetic modification have deep roots in a nineteenth- and twentieth-century tradition of narrative thought-experiments about the artificial reproduction of human life. In the ‘strange wickedness’ to which HG Wells’s narrator refers—as good a condensation of the tradition’s topic as any—strangeness has always been as prominent as wickedness. In that tradition the myths of Prometheus and Faust, of the golem and the doppelgänger, together with fables and fictions concerning automata and scientifically produced monsters and/or reflections on the real and the illusory, have con- verged to define a problematics of the sorcerer’s apprentice. We will see that such a problematics reflects a powerful fear of artifice, or more accurately a phobia: a fear of artifice as great as the attraction it also exerts.

    Five species of sea turtles occur along the United States coastlines and are listed as threatened or endangered. The loggerhead sea turtle (Caretta caretta) is listed as threatened, while the Kemp`s ridley (Lepidochelys kenipi), the hawksbill (Eretmochelys imbricata), and the leatherback (Dermochelys coriacea) are all less abundant and listed as endangered. Florida breeding populations of the green sea turtle (Chelonia mydas) are listed as endangered, but green turtles in other US waters are considered threatened. The National Marine Fisheries Service (NMFS) has determined, based on the best available information, that because of their life cycle and behavioral patterns only the loggerhead, the green, and the Kemp`s ridley are put at risk by hopper dredging activities (Studt 1987).

    The objective of this research is to present the results of the marine chelonians stranding monitoring developed during and after the seismic survey in the north area of Rio de Janeiro and south of Espirito Santo. The monitoring lasted six months, reaching 200 km of beaches, from the Rio de Janeiro North up to the Espirito Santo South coasts. It was conducted by 34 monitors, who covered predefined beach sections daily, registering the stranded animals. At the end of the project, 159 chelonians stranded were registered. The species Chelonia mydas was prevailing in number and distribution. This species make use of this beach area to food. Lepidochelys olivacea was the second species in geographic distribution and number of registers. The other species identified were Caretta caretta and Eretmochelys imbricata. There was only one reproductive register, of Caretta caretta species. (author)

    Documenting the extent of fishery gear interactions is critical to wildlife conservation efforts, especially for reducing entanglements and ingestion. This study summarizes fishery gear interactions involving common bottlenose dolphins (Tursiops truncatus truncatus), Florida manatees (Trichechus manatus latirostris) and sea turtles: loggerhead (Caretta caretta), green turtle (Chelonia mydas), leatherback (Dermochelys coriacea), hawksbill (Eretmochelys imbricata), Kemp's ridley (Lepidochelys kempii), and olive ridley (Lepidochelys olivacea) stranding in Florida waters during 1997-2009. Fishery gear interactions for all species combined were 75.3% hook and line, 18.2% trap pot gear, 4.8% fishing nets, and 1.7% in multiple gears. Total reported fishery gear cases increased over time for dolphins (pgear interaction hotspots were identified and generalized linear regression modeling was conducted. Published by Elsevier Ltd.

    Full Text Available An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras (Echeneidae associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora and four turtle species (Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea are here recorded in symbiotic associations in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis (hitchhiking, albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.

    Adult hawksbill turtles (Eretmochelys imbricata) are typically described as open-coast, coral reef and hard substrate dwellers. Here, we report new satellite tracking data on female hawksbills from several countries in the eastern Pacific that revealed previously undocumented behaviour for adults of the species. In contrast to patterns of habitat use exhibited by their Caribbean and Indo-Pacific counterparts, eastern Pacific hawksbills generally occupied inshore estuaries, wherein they had strong associations with mangrove saltwater forests. The use of inshore habitats and affinities with mangrove saltwater forests presents a previously unknown life-history paradigm for adult hawksbill turtles and suggests a potentially unique evolutionary trajectory for the species. Our findings highlight the variability in life-history strategies that marine turtles and other wide-ranging marine wildlife may exhibit among ocean regions, and the importance of understanding such disparities from an ecological and management perspective.

    2017-12-01

    When applied in vitro, methyl jasmonate is sensed by the red seaweed Grateloupia imbricate, substantially and visually affecting its carposporogenesis. However, although there is some understanding of the morphological changes induced by methyl jasmonate in vitro, little is known about the genes that are involved in red seaweed carposporogenesis and how their protein products act. For the work reported herein, the expression of genes in red seaweed that encode enzymes involved in the synthesis of methyl jasmonate (jasmonic acid carboxyl methyl transferase and a putative methyl transferase) was monitored. Additionally the genes involved in oxidation (cytochrome P450 and WD40), jasmonate synthesis, signal transduction, and regulation of reactive oxygen species (MYB), and reproduction (ornithine decarboxylase) were monitored. To determine when or if the aforementioned genes were expressed during cystocarp development, fertilized and fertile thalli were exposed to methyl jasmonate and gene expression was measured after 24 and 48 h. The results showed that methyl jasmonate promoted differential gene expression in fertilized thalli by 24 h and upregulated expression of the ornithine decarboxylase gene only by 48 h in fertile thalli (0.75 ± 003 copies · μL -1 at 24 h vs. 1.11 ± 0.04 copies · μL -1 at 48 h). We conclude that Ornithine decarboxylase expression involves methyl jasmonate signaling as well as development and maturation of cystocarps. © 2017 Phycological Society of America.

  9. Efectividad del monitoreo de la anidación de tortugas marinas para determinar el éxito reproductivo en playas del sur de Cuba

    Full Text Available El monitoreo de las anidaciones es muy útil como herramienta para la conservación pero el esfuerzo de trabajo en diferentes áreas puede variar grandemente. En Cuba, se aplican cuatro enfoques diferentes: monitoreo sistemático nocturno y diurno (MSN, y monitoreo esporádico con o sin comprobación de nidos (MECC. La cantidad y exactitud de los datos tomados y la calidad de la información derivada de ellos difieren. Por esta razón, en el presente trabajo se evalúa la efectividad de cada enfoque para determinar el éxito reproductivo de tortugas marinas en Cuba. El MSN sólo se realiza en las playas de anidación de la Península de Guanahacabibes, mientras que el MECC es el más extendido en el país. La porción de la temporada de anidación de cada una de las tres especies que anidan en Cuba (Chelonia mydas, Caretta caretta y Eretmochelys imbricata que se cubre con personal de monitoreo es baja para la mayoría de las playas, y sobre todo en el caso de E. imbricata. Se detectaron diferencias entre el monitoreo sistemático y esporádico, por tanto, la capacidad de detectar rastros falsos y verdaderos depende esencialmente de la frecuencia de monitoreo. Esto afecta la capacidad para evaluar el éxito de la anidación por playas. A pesar del incremento en los esfuerzos realizados en Cuba para el seguimiento de las principales colonias de anidación, se deben identificar nuevas estrategias para garantizar la correcta toma de información, y una mayor eficiencia del programa de monitoreo para obtener la mayor información posible de cada una de las especies con un adecuado balance de costo-beneficio.

    2011-05-01

    Full Text Available Strandings and incidental catches of four sea turtles species (Chelonia mydas, Lepidochelys olivacea, Dermochelys coriacea and Eretmochelys imbricata were registered in Tumbes Region since August 2007 to August 2009. These registers (52.6% of strandings and 47.4% of incidental catches occurred during all year; most frequently in Punta Picos (50.5%, Canoas (20.0% and Baja de Punta Mero (14.7%. The most registered species were C. mydas (64.2% and L. olivacea (30.5%; their sizes did not present significant differences between areas and climatic seasons. The higher percentage of C. mydas, L. olivacea and D. coriacea were considered sub-adults, including the only specimen of E. imbricata. The incidental catches were made with gillnets of different mesh sizes, but 8 inches mesh was most frequently. A high proportions of specimens were died with signs of drowning (22.2% this was due to the prolonged time of soak time of gillnet (approximately 12 hours. No significant differences in CPUE were found between climatic seasons and no seasonal pattern was evident. Lesions in 14% of stranded specimens were caused possibly by human attacks or by collisions with fishing boats. 77.8% of incidental catch specimens were sacrificed for the commercialization of his meat, and sometimes of his shell, this shows the lack of awareness of conservation. These observations indicate that the coast of Tumbes is an important foraging area and development of sub-adult specimens of sea turtles; so it is recomend to develop monitoring, awareness and critical areas protection programs to foment the conservation of these organisms in the Eastern Pacific.

    Knowledge of spatial variation in pollutant profiles among sea turtle nesting locations is limited. This poses challenges in identifying processes shaping this variability and sets constraints to the conservation management of sea turtles and their use as biomonitoring tools for environmental pollutants. We aimed to increase understanding of the spatial variation in polycyclic aromatic hydrocarbon (PAH), organochlorine pesticide (OCP) and polychlorinated biphenyl (PCB) compounds among nesting beaches. We link the spatial variation to turtle migration patterns and the persistence of these pollutants. Specifically, using gas chromatography, we confirmed maternal transfer of a large number of compounds (n = 68 out of 69) among 104 eggs collected from 21 nests across three nesting beaches within the Yucatán Peninsula, one of the world's most important rookeries for hawksbill turtles (Eretmochelys imbricata). High variation in PAH profiles was observed among beaches, using multivariate correspondence analysis and univariate Peto-Prentice tests, reflecting local acquisition during recent migration movements. Diagnostic PAH ratios reflected petrogenic origins in Celestún, the beach closest to petroleum industries in the Gulf of Mexico. By contrast, pollution profiles of OCPs and PCBs showed high similarity among beaches, reflecting the long-term accumulation of these pollutants at regional scales. Therefore, spatial planning of protected areas and the use of turtle eggs in biomonitoring needs to account for the spatial variation in pollution profiles among nesting beaches.

  12. The role of turtles as coral reef macroherbivores

    2012-06-29

    Herbivory is widely accepted as a vital function on coral reefs. To date, the majority of studies examining herbivory in coral reef environments have focused on the roles of fishes and/or urchins, with relatively few studies considering the potential role of macroherbivores in reef processes. Here, we introduce evidence that highlights the potential role of marine turtles as herbivores on coral reefs. While conducting experimental habitat manipulations to assess the roles of herbivorous reef fishes we observed green turtles (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata) showing responses that were remarkably similar to those of herbivorous fishes. Reducing the sediment load of the epilithic algal matrix on a coral reef resulted in a forty-fold increase in grazing by green turtles. Hawksbill turtles were also observed to browse transplanted thalli of the macroalga Sargassum swartzii in a coral reef environment. These responses not only show strong parallels to herbivorous reef fishes, but also highlight that marine turtles actively, and intentionally, remove algae from coral reefs. When considering the size and potential historical abundance of marine turtles we suggest that these potentially valuable herbivores may have been lost from many coral reefs before their true importance was understood. © 2012 Goatley et al.

    Climate change poses a unique threat to species with temperature dependent sex determination (TSD), such as marine turtles, where increases in temperature can result in extreme sex ratio biases. Knowledge of the primary sex ratio of populations with TSD is key for providing a baseline to inform management strategies and to accurately predict how future climate changes may affect turtle populations. However, there is a lack of robust data on offspring sex ratio at appropriate temporal and spatial scales to inform management decisions. To address this, we estimate the primary sex ratio of hawksbill hatchlings, Eretmochelys imbricata, from incubation duration of 5514 in situ nests from 10 nesting beaches from two regions in Brazil over the last 27 years. A strong female bias was estimated in all beaches, with 96% and 89% average female sex ratios produced in Bahia (BA) and Rio Grande do Norte (RN). Both inter-annual (BA, 88 to 99%; RN, 75 to 96% female) and inter-beach (BA, 92% to 97%; RN, 81% to 92% female) variability in mean offspring sex ratio was observed. These findings will guide management decisions in Brazil and provide further evidence of highly female-skew sex ratios in hawksbill turtles. Copyright © 2014 Elsevier Ltd. All rights reserved.

    We set out to develop an oviposition induction technique for captive female hawksbill turtles Eretmochelys imbricata. The infertile eggs of nine females were induced to develop by the administration of follicle-stimulating hormone, after which we investigated the effects of administering oxytocin on oviposition. Seven of the turtles were held in a stationary horizontal position on a retention stand, and then oxytocin was administrated (0.6-0.8 units/kg of body weight; 5 mL). The seven turtles were retained for a mandatory 2 h period after oxytocin administration, and were then returned to the holding tanks. As the control, normal saline (5 mL) was administered to the other two turtles, followed by the administration of oxytocin after 24 h. The eggs in oviducts of all nine turtles were observed by ultrasonography at 24 h after oxytocin administration. The control experiment validated that stationary retention and normal saline administration had no effect on egg oviposition. Eight of the turtles began ovipositing eggs at 17-43 min after oxytocin administration, while one began ovipositing in the holding tank immediately after retention. All turtles finished ovipositing eggs within 24 h of oxytocin administration. This report is the first to demonstrate successful induced oviposition in sea turtles. We suggest that the muscles in the oviducts of hawksbill turtles may respond to relatively lower doses of oxytocin (inducing contractions) compared to land and freshwater turtles (4-40 units/kg) based on existing studies.

    2016-03-01

    Full Text Available All of the world’s seven species of marine turtle are threatened by a multitude of anthropogenic pressures across all stages of their life history. The Calamian Islands, Palawan, Philippines provide important foraging and nesting grounds for four species: green turtles (Chelonia mydas, hawksbill turtles (Eretmochelys imbricata, loggerheads (Caretta caretta, and leatherbacks (Dermochelys coriacea. This work aimed to assess the relative importance of turtle nesting beaches and local threats using a combination of social science and ecological research approaches. Endangered green turtles and critically endangered hawksbills were found to nest in the Calamianes. The most important nesting sites were located on the islands off the west of Busuanga and Culion, particularly Pamalican and Galoc and along the north coast of Coron, particularly Linamodio Island. Opportunistic hunting and egg collection, conducted legally by indigenous communities, is the most significant threat to sea turtles in the area. Sites particularly vulnerable to hunting were found to be Galoc Island, Pamalican Island, and Panlaitan Island. Raising awareness, community engagement, and understanding of socio-cultural drivers of sea turtle exploitation, particularly among indigenous communities, are essential to gain support for any effective conservation program. Additionally, more effective enforcement of laws related to the trade in sea turtle products is required to close the commercial and export markets.

  17. Use of Particle Tracking to Determine Optimal Release Dates and Locations for Rehabilitated Neonate Sea Turtles

    Full Text Available Sea turtles found stranded on beaches are often rehabilitated before being released back into the wild. The location and date of release is largely selected on an informal basis, which may not maximize the chance of survival. As oceanic conditions have a large influence on the movements of neonate sea turtles, this study aimed to identify the best locations and months to release rehabilitated sea turtles that would assist in their transport by ocean currents to the habitat and thermal conditions required for their survival. A particle tracking model, forced by ocean surface velocity fields, was used to simulate the dispersal pathways of millions of passively drifting particles released from different locations in Western Australia. The particles represented rehabilitated, neonate turtles requiring oceanic habitats [green (Chelonia mydas, hawksbill (Eretmochelys imbricata and loggerheads (Caretta caretta] and flatback turtles (Natator depressus which require neritic habitats. The results clearly identified regions and months where ocean currents were more favorable for transport to suitable habitats. Tantabiddi, near Exmouth on the north-west coast, was consistently the best location for release for the oceanic species, with dominant offshore-directed currents and a very narrow continental shelf reducing the time taken for particles to be transported into deep water. In contrast, release locations with more enclosed geography, wide continental shelves, and/or proximity to cooler ocean temperatures were less successful. Our results produced a decision support system for the release of neonate marine turtles in Western Australia and our particle tracking approach has global transferability.

Reducing the sediment load of the epilithic algal matrix on a coral reef resulted in a forty-fold increase in grazing by green turtles. Hawksbill turtles were also observed to browse transplanted thalli of the macroalga Sargassum swartzii in a coral reef environment. These responses not only show strong parallels to herbivorous reef fishes, but also highlight that marine turtles actively, and intentionally, remove algae from coral reefs. When considering the size and potential historical abundance of marine turtles we suggest that these potentially valuable herbivores may have been lost from many coral reefs before their true importance was understood.

    Full Text Available The status of marine turtles in Montserrat (Eastern Caribbean is reviewed following five years of monitoring (1999-2003. The mean number of nests recorded during the annual nesting season (June-October was 53 (± 24.9 SD; range: 13-43. In accordance with earlier reports, the nesting of hawksbill (Eretmochelys imbricata and green (Chelonia mydas turtles was confirmed on several beaches around the island. Only non-nesting emergences were documented for loggerhead turtles (Caretta caretta and there was no evidence of nesting by leatherback turtles (Dermochelys coriacea; however, it is possible that additional survey effort would reveal low density nesting by these species. Officially reported turtle capture data for 1993-2003 suggest that a mean of 0.9 turtle per year (±1.2 SD; range: 0-4 were landed island-wide, with all harvest having occurred during the annual open season (1 October to 31 May. Informed observers believe that the harvest is significantly under-reported and that fishermen avoid declaring their catch by butchering turtles at sea (both during and outside the open season. Of concern is the fact that breeding adults are potentially included in the harvest, and that the open season partially coincides with the breeding season. The present study has shown that although Montserrat is not a major nesting site for sea turtles, it remains important on a regional basis for the Eastern Caribbean.

  20. Hawksbill × loggerhead sea turtle hybrids at Bahia, Brazil: where do their offspring go?

    Full Text Available Hybridization between hawksbill (Eretmochelys imbricata and loggerhead (Caretta caretta breeding groups is unusually common in Bahia state, Brazil. Such hybridization is possible because hawksbill and loggerhead nesting activities overlap temporally and spatially along the coast of this state. Nevertheless, the destinations of their offspring are not yet known. This study is the first to identify immature hawksbill × loggerhead hybrids (n = 4 from this rookery by analyzing the mitochondrial DNA (mtDNA of 157 immature turtles morphologically identified as hawksbills. We also compare for the first time modeled dispersal patterns of hawksbill, loggerhead, and hybrid offspring considering hatching season and oceanic phase duration of turtles. Particle movements varied according to season, with a higher proportion of particles dispersing southwards throughout loggerhead and hybrid hatching seasons, and northwards during hawksbill season. Hybrids from Bahia were not present in important hawksbill feeding grounds of Brazil, being detected only at areas more common for loggerheads. The genetic and oceanographic findings of this work indicate that these immature hybrids, which are morphologically similar to hawksbills, could be adopting behavioral traits typical of loggerheads, such as feeding in temperate waters of the western South Atlantic. Understanding the distribution, ecology, and migrations of these hybrids is essential for the development of adequate conservation and management plans.

    Full Text Available This study characterized the morphology of the digestive tube of five species of sea turtles. We used specimens found dead along the coast of the state Rio Grande do Norte, as well as specimens accidentally killed as a result of pelagic longline fishing. Nineteen animals of the following species were analyzed: Chelonia mydas (Linnaeus, 1758 (n = 9, Lepidochelys olivacea (Eschscholtz, 1829 (n = 6, Caretta caretta (Linnaeus, 1758 (n = 2, Eretmochelys imbricata (Linnaeus, 1766 (n = 1 and Dermochelys coriacea (Vandelli, 1761 (n = 1. After opening the plastron, we removed the digestive organs and described the external and internal morphology of each organ. The esophagus of all species had pointed papillae on the mucosa. The stomach varied in shape among species. Differences were found in the mucosa of the small intestine. It was reticular in the duodenum, and longitudinal rectilinear in the jejunum/ileum. In all species an alternation of saccular and narrow regions was observed in the large intestine. The exception was D. coriacea, in which the mucosa of the entire large intestine had irregularly distributed folds. The pattern of the esophagus was the same in all species. The morphology of the stomach differed among species, and these differences reflect their diets. In addition, the distribution pattern of the folds on the mucosa of the small intestine varied between regions of the intestine and among species.

    Full Text Available This study aimed to register the ecological knowledge of fishermen from the municipality of São João de Pirabas, Pará, Brazil, regarding the occurrence of sea turtles on the Pará state coast, as well as measure their incidental capture when fishing; to do this, 50 semi-structured interviews were conducted with local fishermen. Fishing was practiced mostly by adult men, who used 7 fishing arts (gillnetting, hook and line, longline, fish corrals, net of tide canals, casting net, and basket trap, mainly aimed at catching king mackerel (Scomberomorus cavalla, serra Spanish mackerel (S. brasiliensis, king weakfish (Macrodon ancylodon, weakfish (Cynoscion spp., hake (Cynoscion spp., catfish (Bagre bagre, and mullet (Mugil spp.. Fishermen observed in the region 5 turtle species, with a more frequent occurrence of Chelonia mydas (100%, Dermochelys coriacea (66%, and Eretmochelys imbricata (46%; the less frequent species are Caretta caretta (16% and Lepidochelys olivacea (8%. The spawning areas of the 3 most common species demonstrate the significance of the Pará state coast for their conservation. Incidental capture was reported by 76% of fishermen, mainly occurring in net, longlines, and fish corrals. Usually, captured animals were released, although there is consumption of sea turtle meat and eggs by fishermen.

    Full Text Available Sea turtles have existed for millions of years. International Union for Conservation of Nature (IUCN has reported that the Hawksbill Turtle (Eretmochelys imbricata is classified as critically endangered. Turtle excluder device (TED deployment on shrimpnet fisheries is needed for turtle conservation.TED using sound technique is challenge method in fisheries development.The knowledge on turtle hearing capability is limited. The auditory brainstem response (ABR assessment is method to determine turtle hearing capability. Turtle hearing assessment is basis to design TED. The objective of this paper is to determine turtle hearing cability by analyze its ABR spectral.The subject is Hawksbill turtle with number 2 turtles ie: 3 and 2 years. The measurement was taken at Pusat Pengurusan Penyu (Turtle Management Centre Padang Kemunting Masjid Tanah Melaka Malaysia. The results shows that turtle 3 years have peak power frequencies 50.78, 101.6, 152.3, 304.7, 355.5, 457, and 507.8Hz respectively whereas the spectral amplitude is ranging 0.03-32.44% spectral. Turtle 2 years has peak power at 457Hz in whole stimulus frequencies while the spectral amplitude is ranging 0.01-2.5% spectral.

    Full Text Available ABSTRACT Currently, plastics are recognized as a major pollutant of the marine environment, representing a serious threat to ocean wildlife. Here, we examined the occurrence and effects of plastic ingestion by sea turtles found stranded along the coast of Paraíba State, Brazil from August 2009 to July 2010. Ninety-eight digestive tracts were examined, with plastic found in 20 (20.4%. Sixty five percent (n = 13 of turtles with plastic in the digestive tract were green turtles (Chelonia mydas, 25% (n = 5 were hawksbills (Eretmochelys imbricata, and 10% (n = 2 were olive ridley (Lepidochelys olivacea. More plastic was found in the intestine (85% than in other parts of the gastrointestinal tract. We observed complete blockage of the gastrointestinal tract due to the presence of plastic in 13 of the 20 turtles that had ingested plastic. No correlation was found between the curved carapace length (CCL and the number or mass of the plastic ingested items. Significant differences were found between the intake of hard and soft plastic and the ingestion of white/transparent and colored plastic, with soft and white/transparent plastics being more commonly ingested. This study reveals the serious problem of plastic pollution to sea turtles at the area.

    Some of the most basic questions of sea turtle life history are also the most elusive. Many uncertainties surround lifespan, growth rates, maturity and spatial structure, yet these are critical factors in assessing population status. Here we examine the keratinized hard tissues of the hawksbill (Eretmochelys imbricata) carapace and use bomb radiocarbon dating to estimate growth and maturity. Scutes have an established dietary record, yet the large keratin deposits of hawksbills evoke a reliable chronology. We sectioned, polished and imaged posterior marginal scutes from 36 individual hawksbills representing all life stages, several Pacific populations and spanning eight decades. We counted the apparent growth lines, microsampled along growth contours and calibrated Δ(14)C values to reference coral series. We fit von Bertalanffy growth function (VBGF) models to the results, producing a range of age estimates for each turtle. We find Hawaii hawksbills deposit eight growth lines annually (range 5-14), with model ensembles producing a somatic growth parameter (k) of 0.13 (range 0.1-0.2) and first breeding at 29 years (range 23-36). Recent bomb radiocarbon values also suggest declining trophic status. Together, our results may reflect long-term changes in the benthic community structure of Hawaii reefs, and possibly shed light on the critical population status for Hawaii hawksbills. © 2016 The Author(s).

    Sand temperatures at nest depths and implications for hatchling sex ratios of hawksbill turtles (Eretmochelys imbricata) and green turtles (Chelonia mydas) nesting in the Chagos Archipelago, Indian Ocean are reported and compared to similar measurements at rookeries in the Atlantic and Caribbean. During 2012-2014, temperature loggers were buried at depths and in beach zones representative of turtle nesting sites. Data collected for 12,546 days revealed seasonal and spatial patterns of sand temperature. Depth effects were minimal, perhaps modulated by shade from vegetation. Coolest and warmest temperatures were recorded in the sites heavily shaded in vegetation during the austral winter and in sites partially shaded in vegetation during summer respectively. Overall, sand temperatures were relatively cool during the nesting seasons of both species which would likely produce fairly balanced hatchling sex ratios of 53% and 63% male hatchlings, respectively, for hawksbill and green turtles. This result contrasts with the predominantly high female skew reported for offspring at most rookeries around the globe and highlights how local beach characteristics can drive incubation temperatures. Our evidence suggests that sites characterized by heavy shade associated with intact natural vegetation are likely to provide conditions suitable for male hatchling production in a warming world.

  8. Enhancing the use of Argos satellite data for home range and long distance migration studies of marine animals.

    Full Text Available Accurately quantifying animals' spatial utilisation is critical for conservation, but has long remained an elusive goal due to technological impediments. The Argos telemetry system has been extensively used to remotely track marine animals, however location estimates are characterised by substantial spatial error. State-space models (SSM constitute a robust statistical approach to refine Argos tracking data by accounting for observation errors and stochasticity in animal movement. Despite their wide use in ecology, few studies have thoroughly quantified the error associated with SSM predicted locations and no research has assessed their validity for describing animal movement behaviour. We compared home ranges and migratory pathways of seven hawksbill sea turtles (Eretmochelys imbricata estimated from (a highly accurate Fastloc GPS data and (b locations computed using common Argos data analytical approaches. Argos 68(th percentile error was 4 km for LC ≤ 0. Argos error structure was highly longitudinally skewed and was, for all LC, adequately modelled by a Student's t distribution. Both habitat use and migration routes were best recreated using SSM locations post-processed by re-adding good Argos positions (LC 1, 2 and 3 and filtering terrestrial points (mean distance to migratory tracks ± SD = 2.2 ± 2.4 km; mean home range overlap and error ratio = 92.2% and 285.6 respectively. This parsimonious and objective statistical procedure however still markedly overestimated true home range sizes, especially for animals exhibiting restricted movements. Post-processing SSM locations nonetheless constitutes the best analytical technique for remotely sensed Argos tracking data and we therefore recommend using this approach to rework historical Argos datasets for better estimation of animal spatial utilisation for research and evidence-based conservation purposes.

    High seas oceanic ecosystems are considered important habitat for juvenile sea turtles, yet much remains cryptic about this important life-history period. Recent progress on climate and fishery impacts in these so-called lost years is promising, but the developmental biogeography of hawksbill sea turtles (Eretmochelys imbricata) has not been widely described in the Pacific Ocean. This knowledge gap limits the effectiveness of conservation management for this globally endangered species. We address this with 30 years of stranding observations, 20 years of bycatch records, and recent simulations of natal dispersal trajectories in the Hawaiian Archipelago. We synthesize the analyses of these data in the context of direct empirical observations, anecdotal sightings, and historical commercial harvests from the insular Pacific. We find hawksbills 0-4 years of age, measuring 8-34 cm straight carapace length, are found predominantly in the coastal pelagic waters of Hawaii. Unlike other species, we find no direct evidence of a prolonged presence in oceanic habitats, yet satellite tracks of passive drifters (simulating natal dispersal) and our small sample sizes suggest that an oceanic phase for hawksbills cannot be dismissed. Importantly, despite over 600 million hooks deployed and nearly 6000 turtle interactions, longline fisheries have never recorded a single hawksbill take. We address whether the patterns we observe are due to population size and gear selectivity. Although most sea turtle species demonstrate clear patterns of oceanic development, hawksbills in the North Pacific may by contrast occupy a variety of ecosystems including coastal pelagic waters and shallow reefs in remote atolls. This focuses attention on hazards in these ecosystems - entanglement and ingestion of marine debris - and perhaps away from longline bycatch and decadal climate regimes that affect sea turtle development in oceanic regions.

    How individual genetic variability relates to fitness is important in understanding evolution and the processes affecting populations of conservation concern. Heterozygosity-fitness correlations (HFCs) have been widely used to study this link in wild populations, where key parameters that affect both variability and fitness, such as inbreeding, can be difficult to measure. We used estimates of parental heterozygosity and genetic similarity ('relatedness') derived from 32 microsatellite markers to explore the relationship between genetic variability and fitness in a population of the critically endangered hawksbill turtle, Eretmochelys imbricata. We found no effect of maternal MLH (multilocus heterozygosity) on clutch size or egg success rate, and no single-locus effects. However, we found effects of paternal MLH and parental relatedness on egg success rate that interacted in a way that may result in both positive and negative effects of genetic variability. Multicollinearity in these tests was within safe limits, and null simulations suggested that the effect was not an artefact of using paternal genotypes reconstructed from large samples of offspring. Our results could imply a tension between inbreeding and outbreeding depression in this system, which is biologically feasible in turtles: female-biased natal philopatry may elevate inbreeding risk and local adaptation, and both processes may be disrupted by male-biased dispersal. Although this conclusion should be treated with caution due to a lack of significant identity disequilibrium, our study shows the importance of considering both positive and negative effects when assessing how variation in genetic variability affects fitness in wild systems. © 2017 European Society For Evolutionary Biology.

    Full Text Available Marine debris is a growing problem for wildlife, and has been documented to affect more than 267 species worldwide. We investigated the prevalence of marine debris ingestion in 115 sea turtles stranded in Queensland between 2006-2011, and assessed how the ingestion rates differ between species (Eretmochelys imbricata vs. Chelonia mydas and by turtle size class (smaller oceanic feeders vs. larger benthic feeders. Concurrently, we conducted 25 beach surveys to estimate the composition of the debris present in the marine environment. Based on this proxy measurement of debris availability, we modeled turtles' debris preferences (color and type using a resource selection function, a method traditionally used for habitat and food selection. We found no significant difference in the overall probability of ingesting debris between the two species studied, both of which have similar life histories. Curved carapace length, however, was inversely correlated with the probability of ingesting debris; 54.5% of pelagic sized turtles had ingested debris, whereas only 25% of benthic feeding turtles were found with debris in their gastrointestinal system. Benthic and pelagic sized turtles also exhibited different selectivity ratios for debris ingestion. Benthic phase turtles had a strong selectivity for soft, clear plastic, lending support to the hypothesis that sea turtles ingest debris because it resembles natural prey items such as jellyfish. Pelagic turtles were much less selective in their feeding, though they showed a trend towards selectivity for rubber items such as balloons. Most ingested items were plastic and were positively buoyant. This study highlights the need to address increasing amounts of plastic in the marine environment, and provides evidence for the disproportionate ingestion of balloons by marine turtles.

  13. Factors affecting hatch success of hawksbill sea turtles on Long Island, Antigua, West Indies.

    Directory of Open Access Journals (Sweden)

    Mark Allan Ditmer

    Full Text Available Current understanding of the factors influencing hawksbill sea turtle (Eretmochelys imbricata hatch success is disparate and based on relatively short-term studies or limited sample sizes. Because global populations of hawksbills are heavily depleted, evaluating the parameters that impact hatch success is important to their conservation and recovery. Here, we use data collected by the Jumby Bay Hawksbill Project (JBHP to investigate hatch success. The JBHP implements saturation tagging protocols to study a hawksbill rookery in Antigua, West Indies. Habitat data, which reflect the varied nesting beaches, are collected at egg deposition, and nest contents are exhumed and categorized post-emergence. We analyzed hatch success using mixed-model analyses with explanatory and predictive datasets. We incorporated a random effect for turtle identity and evaluated environmental, temporal and individual-based reproductive variables. Hatch success averaged 78.6% (SD: 21.2% during the study period. Highly supported models included multiple covariates, including distance to vegetation, deposition date, individual intra-seasonal nest number, clutch size, organic content, and sand grain size. Nests located in open sand were predicted to produce 10.4 more viable hatchlings per clutch than nests located >1.5 m into vegetation. For an individual first nesting in early July, the fourth nest of the season yielded 13.2 more viable hatchlings than the initial clutch. Generalized beach section and inter-annual variation were also supported in our explanatory dataset, suggesting that gaps remain in our understanding of hatch success. Our findings illustrate that evaluating hatch success is a complex process, involving multiple environmental and individual variables. Although distance to vegetation and hatch success were inversely related, vegetation is an important component of hawksbill nesting habitat, and a more complete assessment of the impacts of specific

    Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily herbivorous mega-consumers that may migrate over hundreds to thousands of kilometers. Our dataset, the largest ever compiled for sea turtles, has 9690 growth increments from 30 sites from Bermuda to Uruguay from 1973 to 2015. Using generalized additive mixed models, we evaluated covariates that could affect growth rates; body size, diet, and year have significant effects on growth. Growth increases in early years until 1999, then declines by 26% to 2015. The temporal (year) effect is of particular interest because two carnivorous species of sea turtles – hawksbills, Eretmochelys imbricata, and loggerheads, Caretta caretta – exhibited similar significant declines in growth rates starting in 1997 in the West Atlantic, based on previous studies. These synchronous declines in productivity among three sea turtle species across a trophic spectrum provide strong evidence that an ecological regime shift (ERS) in the Atlantic is driving growth dynamics. The ERS resulted from a synergy of the 1997/1998 El Niño Southern Oscillation (ENSO) – the strongest on record – combined with an unprecedented warming rate over the last two to three decades. Further support is provided by the strong correlations between annualized mean growth rates of green turtles and both sea surface temperatures (SST) in the West Atlantic for years of declining growth rates (r = -0.94) and the Multivariate ENSO Index (MEI) for all years (r = 0.74). Granger-causality analysis also supports the latter finding. We discuss multiple stressors that could reinforce and prolong the effect of the ERS. This study

    Accelerometers are becoming ever more important sensors in animal-attached technology, providing data that allow determination of body posture and movement and thereby helping to elucidate behaviour in animals that are difficult to observe. We sought to validate the identification of sea turtle behaviours from accelerometer signals by deploying tags on the carapace of a juvenile loggerhead ( Caretta caretta ), an adult hawksbill ( Eretmochelys imbricata ) and an adult green turtle ( Chelonia mydas ) at Aquarium La Rochelle, France. We recorded tri-axial acceleration at 50 Hz for each species for a full day while two fixed cameras recorded their behaviours. We identified behaviours from the acceleration data using two different supervised learning algorithms, Random Forest and Classification And Regression Tree (CART), treating the data from the adult animals as separate from the juvenile data. We achieved a global accuracy of 81.30% for the adult hawksbill and green turtle CART model and 71.63% for the juvenile loggerhead, identifying 10 and 12 different behaviours, respectively. Equivalent figures were 86.96% for the adult hawksbill and green turtle Random Forest model and 79.49% for the juvenile loggerhead, for the same behaviours. The use of Random Forest combined with CART algorithms allowed us to understand the decision rules implicated in behaviour discrimination, and thus remove or group together some 'confused' or under--represented behaviours in order to get the most accurate models. This study is the first to validate accelerometer data to identify turtle behaviours and the approach can now be tested on other captive sea turtle species. © 2018.

    Full Text Available Background: Marine turtles of all species are capable of being toxic. On 17 October 2010, health authorities in the Federated States of Micronesia were notified of the sudden death of three children and the sickening of approximately 20 other people on Murilo Atoll in Chuuk State. The illnesses were suspected to be the result of mass consumption of a hawksbill turtle (Eretmochelys imbricata. An investigation team was assembled to confirm the cause of the outbreak, describe the epidemiology of cases and provide recommendations for control. Methods: We conducted chart reviews, interviewed key informants, collected samples for laboratory analysis, performed environmental investigations and conducted a cohort study. Results: Four children and two adults died in the outbreak and 95 others were sickened; 84% of those who ate the turtle became ill (n = 101. The relative risk for developing illness after consuming the turtle was 11.1 (95% confidence inteval: 4.8–25.9; there was a dose-dependent relationship between amount of turtle meat consumed and risk of illness. Environmental and epidemiological investigations revealed no alternative explanation for the mass illness. Laboratory testing failed to identify a causative agent. Conclusion: We concluded that turtle poisoning (also called chelonitoxism was the cause of the outbreak on Murilo. The range of illness described in this investigation is consistent with previously reported cases of chelonitoxism. This devastating incident highlights the dangers, particularly to children, of consuming turtle meat. Future incidents are certain to occur unless action is taken to alter turtle-eating behaviour in coastal communities throughout the world.

    Full Text Available Nest site selection influences the hatching success of sea turtles and represents a crucial aspect of their reproductive process. Arembepe Beach, in the State of Bahia, northeastern Brazil, is a known nest site for Caretta caretta and Eretmochelys imbricata. For the nesting seasons in 2004/2005 and 2005/2006, we analyzed the influence of beach profile and amount of beach vegetation cover on nest site selection and the hatching success for both species. Loggerhead turtles nested preferentially in the sand zone, while hawksbill turtles demonstrated no preferences for either sand or vegetation zone. Beach vegetation was important in the modulation of nest site selection behavior for both species, but the amount of beach vegetation cover influenced (negatively hatching success only for the hawksbill, mainly via the increment of non-hatched eggs.Hatching success, outside the tide risk zone, was not influenced by the position of the nests along the beach profile. The pattern of nest distribution by species indicated that management of nests at risk of inundation and erosion by the tide is more important for loggerhead turtles than for hawksbill turtles. Beach vegetation is animportant factor in the conservation of these sea turtle species. Nests that are at risk due to tidal inundation and erosion can be translocated to any position along the beach profile without producing any significant effect on hatching success, as long as highdensities of beach vegetation cover are avoided for hawksbill nests. It is important to point out that the pattern we report here for distribution of hawksbill nests along the beach profile could be due in part to the influence of pure and hybrid individuals, since there are reports of hybridization among hawksbills and loggerheads to the study site.

    Full Text Available This study analysed sea turtle strandings on the coast of Paraíba State, Northeastern Brazil, from August 2009 to July 2010. A total of 124 strandings were recorded in this period: green turtle Chelonia mydas (n = 106, hawksbill Eretmochelys imbricata (n = 15, olive ridley Lepidochelys olivacea (n = 2 and loggerhead Caretta caretta (n = 1. Of all turtles for which the Curved Carapace Length (CCL was measured (n = 122, only 12 individuals (9.7% were adults. Twenty individuals had synthetic anthropogenic debris in the gastrointestinal tract. Other traces of human interactions were observed in 43 individuals, such as injuries caused by entanglement in fishing lines or nets, collisions with vessels, direct contact with oil spills and lesions caused by sharp or spiked objects. Moreover, in 28.5% of the stranded turtles, the presence of external tumors was noticed, suggestive of fibropapillomatosis and in 9.7%, shark bite marks were observed. Of the 107 individuals that were sexed, 76 were females and 31 were males. Most turtles (72.6% became stranded during the spring/summer (between October and March. We found evidence of human interactions (injuries in half of the strandings, but in most cases it was not possible to determine if such interactions were the cause of death. A logistic regression found a significant relationship between CCL, ingestion of debris and lesions caused by sharks or spiked objects. Systematic data collection from stranded sea turtles can provide useful biological information, such as seasonal and spatial patterns in their occurrence and mortality, age structure, sex ratio and diet, as well as possible mortality causes.

    Hawksbill turtle (Eretmochelys imbricata) populations have experienced global decline because of a history of intense commercial exploitation for shell and stuffed taxidermied whole animals, and harvest for eggs and meat. Improved understanding of genetic diversity and phylogeography is needed to aid conservation. In this study, we analyzed the most geographically comprehensive sample of hawksbill turtles from the Indo-Pacific Ocean, sequencing 766 bp of the mitochondrial control region from 13 locations (plus Aldabra, n = 4) spanning over 13500 km. Our analysis of 492 samples revealed 52 haplotypes distributed in 5 divergent clades. Diversification times differed between the Indo-Pacific and Atlantic lineages and appear to be related to the sea-level changes that occurred during the Last Glacial Maximum. We found signals of demographic expansion only for turtles from the Persian Gulf region, which can be tied to a more recent colonization event. Our analyses revealed evidence of transoceanic migration, including connections between feeding grounds from the Atlantic Ocean and Indo-Pacific rookeries. Hawksbill turtles appear to have a complex pattern of phylogeography, showing a weak isolation by distance and evidence of multiple colonization events. Our novel dataset will allow mixed-stock analyses of hawksbill turtle feeding grounds in the Indo-Pacific by providing baseline data needed for conservation efforts in the region. Eight management units are proposed in our study for the Indo-Pacific region that can be incorporated in conservation plans of this critically endangered species. © The American Genetic Association. 2015.

    Drones are being increasingly used in innovative ways to enhance environmental research and conservation. Despite their widespread use for wildlife studies, there are few scientifically justified guidelines that provide minimum distances at which wildlife can be approached to minimize visual and auditory disturbance. These distances are essential to ensure that behavioral and survey data have no observer bias and form the basis of requirements for animal ethics and scientific permit approvals. In the present study, we documented the behaviors of three species of sea turtle (green turtles, Chelonia mydas, flatback turtles, Natator depressus, hawksbill turtles, Eretmochelys imbricata), saltwater crocodiles (Crocodylus porosus), and crested terns (Thalasseus bergii) in response to a small commercially available (1.4 kg) multirotor drone flown in Northern Territory and Western Australia. Sea turtles in nearshore waters off nesting beaches or in foraging habitats exhibited no evasive behaviors (e.g. rapid diving) in response to the drone at or above 20-30 m altitude, and at or above 10 m altitude for juvenile green and hawksbill turtles foraging on shallow, algae-covered reefs. Adult female flatback sea turtles were not deterred by drones flying forward or stationary at 10 m altitude when crawling up the beach to nest or digging a body pit or egg chamber. In contrast, flyovers elicited a range of behaviors from crocodiles, including minor, lateral head movements, fleeing, or complete submergence when a drone was present below 50 m altitude. Similarly, a colony of crested terns resting on a sand-bank displayed disturbance behaviors (e.g. flight response) when a drone was flown below 60 m altitude. The current study demonstrates a variety of behavioral disturbance thresholds for diverse species and should be considered when establishing operating conditions for drones in behavioral and conservation studies.

    Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily herbivorous mega-consumers that may migrate over hundreds to thousands of kilometers. Our dataset, the largest ever compiled for sea turtles, has 9690 growth increments from 30 sites from Bermuda to Uruguay from 1973 to 2015. Using generalized additive mixed models, we evaluated covariates that could affect growth rates; body size, diet, and year have significant effects on growth. Growth increases in early years until 1999, then declines by 26% to 2015. The temporal (year) effect is of particular interest because two carnivorous species of sea turtles-hawksbills, Eretmochelys imbricata, and loggerheads, Caretta caretta-exhibited similar significant declines in growth rates starting in 1997 in the West Atlantic, based on previous studies. These synchronous declines in productivity among three sea turtle species across a trophic spectrum provide strong evidence that an ecological regime shift (ERS) in the Atlantic is driving growth dynamics. The ERS resulted from a synergy of the 1997/1998 El Niño Southern Oscillation (ENSO)-the strongest on record-combined with an unprecedented warming rate over the last two to three decades. Further support is provided by the strong correlations between annualized mean growth rates of green turtles and both sea surface temperatures (SST) in the West Atlantic for years of declining growth rates (r = -.94) and the Multivariate ENSO Index (MEI) for all years (r = .74). Granger-causality analysis also supports the latter finding. We discuss multiple stressors that could reinforce and prolong the effect of the ERS. This study demonstrates the

    Full Text Available In order to provide information to better inform management decisions and direct further research, vessel-based visual transects, snorkel transects, and in-water capture techniques were used to characterize hawksbill sea turtles in the shallow marine habitats of a Marine Protected Area (MPA, the Key West National Wildlife Refuge in the Florida Keys. Hawksbills were found in hardbottom and seagrass dominated habitats throughout the Refuge, and on man-made rubble structures in the Northwest Channel near Cottrell Key. Hawksbills captured (N = 82 were exclusively juveniles and subadults with a straight standard carapace length (SSCL ranging from 21.4 to 69.0cm with a mean of 44.1 cm (SD = 10.8. Somatic growth rates were calculated from 15 recaptured turtles with periods at large ranging from 51 to 1188 days. Mean SSCL growth rate was 7.7 cm/year (SD = 4.6. Juvenile hawksbills (<50 cm SSCL showed a significantly higher growth rate (9.2 cm/year, SD = 4.5, N = 11 than subadult hawksbills (50-70 cm SSCL, 3.6 cm/year, SD = 0.9, N = 4. Analysis of 740 base pair mitochondrial control region sequences from 50 sampled turtles yielded 12 haplotypes. Haplotype frequencies were significantly different compared to four other Caribbean juvenile foraging aggregations, including one off the Atlantic coast of Florida. Many-to-one mixed stock analysis indicated Mexico as the primary source of juveniles in the region and also suggested that the Refuge may serve as important developmental habitat for the Cuban nesting aggregation. Serum testosterone radioimmunoassay results from 33 individuals indicated a female biased sex ratio of 3.3 females: 1 male for hawksbills in the Refuge. This assemblage of hawksbills is near the northern limit of the species range, and is one of only two such assemblages described in the waters of the continental United States. Since this assemblage resides in an MPA with intensive human use, basic information on the assemblage is vital to resource managers charged with conservation and species protection in the MPA.

    Somatic growth dynamics are an integrated response to environmental conditions. Hawksbill sea turtles (Eretmochelys imbricata) are long-lived, major consumers in coral reef habitats that move over broad geographic areas (hundreds to thousands of kilometers). We evaluated spatio-temporal effects on hawksbill growth dynamics over a 33-yr period and 24 study sites throughout the West Atlantic and explored relationships between growth dynamics and climate indices. We compiled the largest ever data set on somatic growth rates for hawksbills – 3541 growth increments from 1980 to 2013. Using generalized additive mixed model analyses, we evaluated 10 covariates, including spatial and temporal variation, that could affect growth rates. Growth rates throughout the region responded similarly over space and time. The lack of a spatial effect or spatio-temporal interaction and the very strong temporal effect reveal that growth rates in West Atlantic hawksbills are likely driven by region-wide forces. Between 1997 and 2013, mean growth rates declined significantly and steadily by 18%. Regional climate indices have significant relationships with annual growth rates with 0- or 1-yr lags: positive with the Multivariate El Niño Southern Oscillation Index (correlation = 0.99) and negative with Caribbean sea surface temperature (correlation = −0.85). Declines in growth rates between 1997 and 2013 throughout the West Atlantic most likely resulted from warming waters through indirect negative effects on foraging resources of hawksbills. These climatic influences are complex. With increasing temperatures, trajectories of decline of coral cover and availability in reef habitats of major prey species of hawksbills are not parallel. Knowledge of how choice of foraging habitats, prey selection, and prey abundance are affected by warming water temperatures is needed to understand how climate change will affect productivity of consumers that live in association with coral reefs.

    Inorganic elements (Pb, Cd, Hg, Al, As, Cr, Cu, Fe, Mn, Ni, Se and Zn) are present globally in aquatic systems and their potential transfer to marine turtles can be a serious threat to their health status. The environmental fate of these contaminants may be traced by the analysis of turtle tissues. Loggerhead turtles (Caretta caretta) are the most frequently investigated of all the sea turtle species with regards to inorganic elements, followed by Green turtles (Chelonia mydas); all the other species have considerably fewer studies. Literature shows that blood, liver, kidney and muscle are the tissues most frequently used for the quantification of inorganic elements, with Pb, Cd, Cu and Zn being the most studied elements. Chelonia mydas showed the highest concentrations of Cr in muscle (4.8 ± 0.12), Cu in liver (37 ± 7) and Mg in kidney (17 μg g -1 ww), Cr and Cu from the Gulf of Mexico and Mg from Japanese coasts; Lepidochelys olivacea presented the highest concentrations of Pb in blood (4.46 5) and Cd in kidney (150 ± 110 μg g -1 ww), both from the Mexican Pacific; Caretta caretta from the Mediterranean Egyptian coast had the highest report of Hg in blood (0.66 ± 0.13 μg g -1 ww); and Eretmochelys imbricata from Japan had the highest concentration of As in muscle (30 ± 13 13 μg g -1 ww). The meta-analysis allows us to examine some features that were not visible when data was analyzed alone. For instance, Leatherbacks show a unique pattern of concentration compared to other species. Additionally, contamination of different tissues shows some tendencies independent of the species with liver and kidney on one side and bone on the other being different from other tissues. This review provides a general perspective on the accumulation and distribution of these inorganic elements alongside existing information for the 7 sea turtle species. Copyright © 2017 Elsevier Ltd.

    within a short period of time and then, when thermal conditions within the nest are uniform, develop at very similar rates and hence hatch and emerge together (Porter 1972). As a corollary of this idea, it would be predicted that when there are pronounced within-nest thermal gradients, development rates of siblings will be different and hence asynchronous hatching and emergence might occur. While it may be energetically beneficial for hatchlings to emerge in a group (Carr and Hirth 1961), if the extent of hatching asynchrony is marked then there may be severe costs for individuals if they wait for all their siblings to hatch before attempting to dig out of the sand (Hays and Speakman 1992). Under such conditions, the protracted emergence of small groups of hatchlings over several nights may be favoured. Examination of the literature suggests that emergence asynchrony may be more widespread than generally considered. For example, Witherington et al. (1990) described loggerhead turtle hatchlings (Caretta caretta) emerging over 4 days in Florida; for green turtles (Chelonia mydas), Hendrickson (1958) documented that nests in Malaysia and Sarawak produced hatchlings for up to 8 days; whilst Diamond (1976) found that hawksbill (Eretmochelys imbricata) nests on Cousin Island, Seychelles, were active for up to 4 days. Similarly, on the Greek Island of Kefalonia, we have shown that emergence from individual loggerhead turtle nests may occur on up to 11 nights (Hays and Speakman 1992). It is logical to suppose that asynchronous emergence relates to thermal gradients within nests, since the incubation duration of sea turtle eggs is related to temperature, with eggs hatching quicker when the temperature is higher. Here we test this hypothesis by measuring thermal variations within loggerhead turtle nests and comparing these variations to the patterns of hatchling emergence.

  6. Distinguishing suitable biotypes of Dactylopius tomentosus (Hemiptera: Dactylopiidae) for biological control of Cylindropuntia fulgida var. fulgida (Caryophyllales: Cactaceae) in South Africa.

    Mathenge, C W; Holford, P; Hoffmann, J H; Zimmermann, H G; Spooner-Hart, R; Beattie, G A C

    2009-12-01

    Cylindropuntia fulgida (Engelmann) F.M. Knuth var. fulgida (Engelmann) F.M. Knuth (Cff) (Caryophyllales: Cactaceae) is native to Mexico and Arizona and was introduced into South Africa for ornamental purposes. It subsequently became highly invasive, necessitating control. The cochineal insect, Dactylopius tomentosus (Lamarck) (Hemiptera: Dactylopiidae), was selected as a potential biological control agent based on its restricted host range among Cylindropuntia species and previous success in controlling C. imbricata (DC.) F. Knuth (Ci). Eight D. tomentosus provenances (Cholla, Cholla E, Fulgida, Mamillata, Imbricata, Tunicata U, Tunicata V and Rosea) from Cylindropuntia species in their native ranges were reared on Cff, whilst Cholla and Imbricata were also reared on Ci. Large differences were found in the development and survival of crawlers, and in the reproductive capacity of females. Three subjective categories of provenance interaction with host plants were identified based on a fitness index (FI) calculated from data relating to crawler survival, female development time and fecundity: (i) thriving (FI > or = 1) - insects had shorter developmental times, high crawler survival and highly fecund females (Cholla); (ii) surviving (FI0) - insects had extended development times, low crawler survival and low fecundity (Imbricata, Fulgida and Mamillata); and (iii) dying (FI = 0) - insects died before or at the second instar (Rosea, Tunicata U and Tunicata V). Cholla, therefore, is highly suitable for biological control of Cff in South Africa. In addition, Cholla thrived on Cff but only survived on Ci whilst, in contrast, Imbricata thrived on Ci but only survived on Cff. This differential ability of provenances to thrive or survive on different host plants demonstrated that host adapted biotypes of D. tomentosus exist; therefore, biotypes should be taken into account when considering this species as a biological control agent of cactus weeds.

Esta investigación evaluó el efecto del fuego sobre la riqueza de especies de HMA asociada a Cylindropuntia imbricata , Mimosa biuncifera y Zaluziana augusta . En el Parque Ecológico “Cubitos” de Pachuca, Hidalgo, se seleccionaron dos matorrales xerófilos: i conservado y ii perturbado por un incendio forestal. En cada matorral y de tres individuos de C. imbricata , M. biuncifera , Z. augusta y en áreas abiertas (AA libres de plantas, se recolectaron muestras de suelo (1 kg para la extracción de esporas y determinar la riqueza taxonómica de HMA por género y especie, así como la humedad y pH del suelo. Con un análisis de varianza, similitud y correspondencia se analizaron estas variables. La riqueza de HMA consistió de once morfo-especies distribuidas en seis familias. M. biuncifera en el sitio conservado presentó la mayor riqueza de HMA a nivel de género (6 y especie (6 y en el sitio perturbado fue C. imbricata con cuatro géneros y seis especies. El fuego redujo la riqueza de especies de HMA en un 50, 25 y 50% en M. biuncifera , Z. augusta y en las AA, respectivamente; mientras que, en C. imbricata se incrementó en un 34 %. La familia Gigasporaceae sólo estuvo asociada a M. biuncifera y Z. augusta en la condición conservada. El análisis de correspondencia sugiere que la identidad de la especie vegetal afecta la composición de especies de HMA.

  19. Statistical Thermodynamics and Microscale Thermophysics

    Science.gov (United States)

    Carey, Van P.

    1999-08-01

    Many exciting new developments in microscale engineering are based on the application of traditional principles of statistical thermodynamics. In this text Van Carey offers a modern view of thermodynamics, interweaving classical and statistical thermodynamic principles and applying them to current engineering systems. He begins with coverage of microscale energy storage mechanisms from a quantum mechanics perspective and then develops the fundamental elements of classical and statistical thermodynamics. Subsequent chapters discuss applications of equilibrium statistical thermodynamics to solid, liquid, and gas phase systems. The remainder of the book is devoted to nonequilibrium thermodynamics of transport phenomena and to nonequilibrium effects and noncontinuum behavior at the microscale. Although the text emphasizes mathematical development, Carey includes many examples and exercises to illustrate how the theoretical concepts are applied to systems of scientific and engineering interest. In the process he offers a fresh view of statistical thermodynamics for advanced undergraduate and graduate students, as well as practitioners, in mechanical, chemical, and materials engineering.

  20. From Headline to Hard Grind: The Importance of Understanding Public Administration in Achieving Health Outcomes

    Science.gov (United States)

    O’Flynn, Janine

    2016-01-01

    Many public policy programs fail to translate ambitious headlines to on-the-ground action. The reasons for this are many and varied, but for public administration and management scholars a large part of the gap between ambition and achievement is the challenge associated with the operation of the machinery of government itself, and how it relates to the other parties that it relies on to fulfill these outcomes. In their article, Carey and Friel set out key reasons why public health scholars should seek to better understand important ideas in public administration. In commenting on their contribution, I draw out two critical questions that are raised by this discussion: (i) what are boundaries and what forms do they take? and (ii) why work across boundaries? Expanding on these key questions extends the points made by Carey and Friel on the importance of understanding public administration and will better place public health scholars and practitioners to realise health outcomes.

    According to the syndicated loan pricing puzzle (Carey and Nini, Journal of Finance, 2007) interest rates charged to corporate borrowers are lower in Europe than in the U.S. Our investigation suggests that controlling for region-specific credit ratings makes the Europe-U.S. gap insignificant, and solves the puzzle. We speculate that the puzzle originates from the lack of uniformity of accounting standards.

  16. Some Physiological Adaptations to Drought in Xerohalophytic Plants Inhabiting Two Oases in Western Desert of Egypt

    International Nuclear Information System (INIS)

    Rayan, A M; Farghali, K A

    2007-01-01

    Under natural drought, some physiological parameters were measured in some wild species inhabiting the western desert of Egypt. Seasonal changes of nitrogen metabolites and Na/K ratio were detected in the investigated species. Effect of seasons, species, and their interaction played an important role on total free amino acids, soluble proteins and Na/K ratio at two oases (Dakhla and Kharga). Species diversity showed more effective variable in regulating such metabolites at Kharga oasis. Plants responded to their environment in two ways, either by increasing their water binding molecules or by preventing the formation of amino acids into proteins. Some of the halophytic and xerophytic species may adjust osmotically to stress by the contribution of nitrogen metabolites. On the other hand, Zygophyllum coccineum, the succulent plant, may adapt to environmental conditions through the accumulation of free amino acids. Correlation analysis between Na+/K+ ratio with free amino acids, soluble proteins and water content in Tamarix aphylla, Salsola imbricata, Balanites aegyptiaca, Trichodesma africanum, and Z. coccineum (Kharga) indicated changes in ionic fraction or accumulating soluble organic compounds which were osmotically active and contribute to osmotic adjustment. Correlations were found between chlorophyll content, ionic and nitrogen metabolites. In Acacia nilotica, Suaeda monoica and Z. coccineum at Dakhla oasis, changes in soluble proteins or ionic ratio could be caused by chlorophyll response to stress, while S. imbricata and T. aphylla may control cellular protein contents. On the other hand, the sharing of both free amino acids and ionic fraction may play an important role of osmoregulation in S. imbricata, Citrullus colocynthis and Z. coccineum at Kharga oasis.

  17. Revised tephra volumes for Cascade Range volcanoes

    Science.gov (United States)

    Nathenson, Manuel

    2017-01-01

    Isopach maps from tephra eruptions from Mount St. Helens were reported in Carey et al. (1995) and for tephra eruptions from Glacier Peak in Gardner et al. (1998). For exponential thinning, the isopach data only define a single slope on a log thickness versus square root of area plot. Carey et al. (1995) proposed a model that was used to estimate a second slope, and volumes were presented in both studies using this model. A study by Sulpizio (2005) for estimating the second slope and square root of area where the lines intersect involves a systematic analysis of many eruptions to provide correlation equations. The purpose of this paper is to recalculate the volumes of Cascades eruptions and compare results from the two methods. In order to gain some perspective on the methods for estimating the second slope, we use data for thickness versus distance beyond the last isopach that are available for some of the larger eruptions in the Cascades. The thickness versus square root of area method is extended to thickness versus distance by developing an approximate relation between the two assuming elliptical isopachs with the source at one of the foci. Based on the comparisons made between the Carey et al. (1995) and Sulpizio (2005) methods, it is felt that the later method provides a better estimate of the second slope. For Mount St. Helens, the estimates of total volume using the Sulpizio (2005) method are generally smaller than those using the Carey et al. (1995) method. For the volume estimates of Carey et al. (1995), the volume of the May 18, 1980, eruption of Mount St. Helens is smaller than six of the eight previous eruptions. With the new volumes using the Sulpizio (2005) method, the 1980 eruption is smaller in volume than the upper end of the range for only three of the layers (Wn, Ye, and Yn) and is the same size as layer We. Thus the 1980 eruption becomes representative of the mid-range of volumes rather than being in the lower range.

  18. Expansion of plants with Crassulacean Acid Metabolism under global environment change

    Science.gov (United States)

    Yu, K.; D'Odorico, P.; Collins, S. L.; Carr, D.

    2016-12-01

    The abundance of plants with Crassulacean Acid Metabolism (CAM) has increased in many drylands worldwide. This is hypothesized to occur because CAM plants store water, take up CO2 at night, exhibit photosynthetic plasticity, and have high water use efficiency. The increased dominance of CAM plants, however, also depends on their competitive relationship with other functional groups, an aspect of CAM plant sensitivity to global environmental change that has remained largely understudied. Here, we investigated the response of CAM plants and their competitive relationships with C3 and C4 plants under global environmental change. We focused on two pairs of CAM and non-CAM species, namely Cylindropuntia imbricata (a constitutive CAM species) and Bouteloua eriopoda (C4 grass), which co-occur in desert grasslands in northern Mexico, and invasive Mesembryanthemum crystallinum (a facultative CAM species) and Bromus mollis (a C3 invasive grass), which coexist in California's coastal grasslands. A set of growth chamber experiments under altered CO2 and water conditions show that C. imbricata outcompeted B. eriopoda under drought conditions, while in well-watered conditions B. eriopoda was a stronger competitor for soil water than C. imbricata. Under drought conditions a more positive response to CO2 enrichment by C. imbricata indirectly disfavored B. eriopoda, which suggests that interspecific competition can outweigh the favorable direct effect of CO2 enrichment on plant growth. A set of greenhouse experiments under water, N, and soil salinity manipulations showed that drought, N deposition, and/or increased soil salinity served as important drivers for success of M. crystallinum invasion, while B. mollis exerted strong competitive effects on M. crystallinum for light and soil nutrients in well-watered conditions. M. crystallinum switched from C3 photosynthesis to CAM photosynthesis as an adaptive strategy in response to moderate intensity of competition from B. mollis, in

    Full Text Available Root-knot nematode, Meloidogyne javanica (Treub Chitwood is a soil-borne plant pathogen of roots. Nematode infection results in altered plant growth and physicochemical processes due to gall formation. Many plants contain unique biochemicals that have biocidal properties and offer a potential novel approach to suppress the nematode populations in soil and improve growth of crop plants. In the present study effect of some indigenous halophytic plant species (Tamarix indica Willd, Suaeda fruticosa Forssk and Salsola imbricata (Schultz Dandy were tested against M. javanica. Tested halophytes significantly (P<0.001 reduced egg hatching and caused mortality of second stage juveniles (J2 in vitro.

    Full Text Available El presente artículo expone la teoría explicativa propuesta por Carey para el cambio conceptual. Primeramente, se plantea la cuestión de la reorganización conceptual en la psicología cognitiva y la posición de Carey. En segundo lugar, se ponen de relieve las condiciones epistémica que deben cumplir las "teorías" infantiles para que la reestructuración conceptual sea posible, así como los modos que adopta esta última. En tercer lugar, se muestran los resultados de investigaciones que verifican el cambio conceptual entre teorías infantiles de biología intuitiva. En cuarto lugar, se plantean las dificultades de otras teorías del cambio conceptual, para luego formular los rasgos del mecanismo alternativo de bootstrapping y su pertinencia para interpretrar los datos de las indagaciones mencionadas. Finalmente, se evalúan la originalidad de la teoría del bootstrpping en el escenario de los debates contemporáneos. Muy especialmente, se esboza una posible aproximación con las tesis dialécticas de Piaget.This paper examines the Carey's theory of conceptual change. First, it describes the conceptual reorganization in cognitive psychology and the author position. Second, the epistemic conditions that children "theories" should fulfil to make conceptual restructuring possible, as well as the ways adopted by the latter, are analyzed. In third place, findings of researches testing the conceptual change among biology intuitive children theories are explained. Subsequently, it discusses the difficulties other theories of conceptual change present, in order to state features of bootstrapping as an alternative mechanism and its relevance for the interpretation of abovementioned researches results. Finally, it evaluates the originality of "bootstrapping" theory in the scene of contemporary debates. It particularly outlines a possible approach to Piaget's dialectic theses.

    We review briefly the different constraints on the three right-handed neutrinos of the {nu}MSM, an extension of the Standard Model that can explain baryon asymmetry, dark matter and neutrino masses. We include in the discussion the proposed experiments on muon to electron conversion Mu2e (Carey et al., Mu2e Collaboration, 2012), COMET and PRISM (Hungerford, COMET Collaboration, AIP Conf Proc 1182:694, 2009; Cui et al., COMET Collaboration, 2012). We find that the expected sensitivity of these experiments is weaker by about two orders of magnitude than the constraints coming from successful baryogenesis.

    The purpose of this study was to determine the taxonomic composition, abundance, and food habits of grasshopper populations inhabiting the 200 Area plateau. Two sites were selected for detailed study, one near the B-C Cribs control zone and the other near the former REDOX Pond. A total of 14 grasshopper species were collected from the B-C Cribs study area and 16 species from the REDOX Pond area. Thirteen of these species occurred at both locations. Population density was low throughout most of the spring, increased in late May, and reached a peak of about 4 grasshoppers per square meter in early July. A dietary analysis showed that 7 of the 28 species of vascular plants recorded from the area were major components in grasshopper diets. These included needle-and-thread grass (Stipa comata), turpentine cymopterus (Cymopterus terebinthinus), Carey's balsamroot (Balsamorhiza careyana), western tansymustard (Descurainia pinnata), Jim Hill mustard (Sisymbrium altissimum), big sagebrush (Artemisia tridentata) and green rabbitbrush (Chrysothamnus viscidiflorus). The plant most heavily utilized was big sagebrush, followed by turpentine cymopterus, green rabbitbrush, and Carey's balsamroot. Other species were less frequently eaten. Several plants were present in the diet at a much higher frequency than they occurred in the environment, indicating that they were preferred food items.

    Meditation is important in facilitating health. Pregnancy health has been shown to have significant consequences for infant behaviors. In view of limited studies on meditation and infant temperament, this study aims to explore the effects of prenatal meditation on these aspects. The conceptual framework was based on the postulation of positive relationships between prenatal meditation and infant health. A randomized control quantitative study was carried out at Obstetric Unit, Queen Elizabeth Hospital in Hong Kong. 64 pregnant Chinese women were recruited for intervention and 59 were for control. Outcome measures were cord blood cortisol, infant salivary cortisol, and Carey Infant Temperament Questionnaire. Cord blood cortisol level of babies was higher in the intervention group (pmeditation can influence fetal health. Carey Infant Temperament Questionnaire showed that the infants of intervention group have better temperament (pmeditation in relation to child health. Present study concludes the positive effects of prenatal meditation on infant behaviors and recommends that pregnancy care providers should provide prenatal meditation to pregnant women.

    2016-04-30

    Many public policy programs fail to translate ambitious headlines to on-the-ground action. The reasons for this are many and varied, but for public administration and management scholars a large part of the gap between ambition and achievement is the challenge associated with the operation of the machinery of government itself, and how it relates to the other parties that it relies on to fulfill these outcomes. In their article, Carey and Friel set out key reasons why public health scholars should seek to better understand important ideas in public administration. In commenting on their contribution, I draw out two critical questions that are raised by this discussion: (i) what are boundaries and what forms do they take? and (ii) why work across boundaries? Expanding on these key questions extends the points made by Carey and Friel on the importance of understanding public administration and will better place public health scholars and practitioners to realise health outcomes. © 2016 by Kerman University of Medical Sciences.

  1. Understanding the nature of science and scientific progress: A theory-building approach

    Directory of Open Access Journals (Sweden)

    2010-11-01

    Full Text Available In 1993 Carey and Smith conjectured that the most promising way to boost students’ understanding of the nature of science is a “theory-building approach to teaching about inquiry.” The research reported here tested this conjecture by comparing results from two Grade 4 classrooms that differed in their emphasis on and technological support for creating and improving theories. One class followed a Knowledge Building approach and used Knowledge Forum®, which together emphasize theory improvement and sustained creative work with ideas. The other class followed an inquiry approach mediated through collaborative project-based activities. Apart from this, the two classes were demographically similar and both fell within the broad category of constructivist, inquiry-based approaches and employed a range of modes and media for investigative research and reports. An augmented version of Carey and Smith’s Nature of Science Interview showed that the Knowledge Building approach resulted in deeper understanding of the nature of theoretical progress, the connections between theories and facts, and the role of ideas in scientific inquiry.

    Full Text Available Dermatophyte infection may present in the form of concentric rings caused by Trichophyton concentricum, known as Tinea Imbricata. In immunosuppressed patients, there are reports of lesions in the form of concentric rings caused by dermatophytes other than Trichophyton concentricum too, mostly by Trichophyton tonsurans, known as Tinea indesiciva or Tinea pseudoimbricata. We report a case of tinea capitis in a HIV-positive adult woman on antiretroviral therapy, who presented with concentric rings of papules and pustules with slight scaling on the scalp along with diffuse thinning of hair. Both Potassium hydroxide mount and culture showed the presence of Dermatophytes. Tinea capitis is considered rare in adults, but new cases are being reported in immunocompromised as well as in immunocompetent patients. The pertinent features of this case are: HIV-positive adult female on antiretroviral therapy, presenting with tinea capitis in the form of concentric rings; culture from the lesion grew Microsporum audouinii; responding to oral Terbinafine.

    Subsequent to the 2008 E-Area Low-Level Waste Facility (ELLWF) Performance Assessment (PA) (WSRC 2008), two additional E-Area vault concrete property testing programs have been conducted (Dixon and Phifer 2010 and SIMCO 2011a) and two additional E-Area vault concrete durability modeling projections have been made (Langton 2009 and SIMCO 2012). All the information/data from these reports has been evaluated and consolidated herein by the Savannah River National Laboratory (SRNL) at the request of Solid Waste Management (SWM) to produce E-Area vault concrete hydraulic and physical property data and vault durability/degradation projection recommendations that are adequately justified for use within associated Special Analyses (SAs) and future PA updates. The Low Activity Waste (LAW) and Intermediate Level (IL) Vaults structural degradation predictions produced by Carey 2006 and Peregoy 2006, respectively, which were used as the basis for the 2008 ELLWF PA, remain valid based upon the results of the E-Area vault concrete durability simulations reported by Langton 2009 and those reported by SIMCO 2012. Therefore revised structural degradation predictions are not required so long as the mean thickness of the closure cap overlying the vaults is no greater than that assumed within Carey 2006 and Peregoy 2006. For the LAW Vault structural degradation prediction (Carey 2006), the mean thickness of the overlying closure cap was taken as nine feet. For the IL Vault structural degradation prediction (Peregoy 2006), the mean thickness of the overlying closure cap was taken as eight feet. The mean closure cap thicknesses as described here for both E-Area Vaults will be included as a key input and assumption (I&A) in the next revision to the closure plan for the ELLWF (Phifer et al. 2009).

    Adolescent males interested in sex with males (AMSM) are an important audience for HIV prevention interventions, but they are difficult to reach due to their age and social stigma. We aim to identify efficient methods to recruit and retain AMSM in online research. Interviews with 14-to-18-year-old AMSM (N=16) were conducted at 2017 Pride events in Boston, MA and Providence, RI. Participants reported that (1) social media platforms are viable recruitment venues; (2) recruitment advertisements should describe the study using colorful/bright pictures, familiar words, and information about compensation; (3) surveys should be recruitment and retention procedures to increase the efficiency of HIV prevention research for this at-risk group. ©Kimberly M Nelson, Jaime J Ramirez, Michael P Carey.

  7. Factors limiting the recovery of boreal toads (Bufo b. boreas)

    2005-01-01

    Boreal toads (Bufo b. boreas) are widely distributed over much of the mountainous western United States. Populations in the Southern Rocky Mountains suffered extensive declines in the late 1970s through early 1980s (Carey, 1993). At the time, these mass mortalities were thought to be associated with a bacterial infection (Carey, 1993). Although the few populations that survived the mass die-offs were not systematically monitored until at least 1993, no mass mortalities had been observed until 1996 when die-offs were observed. A mycotic skin infection associated with a chytrid fungus is now causing mortality of toads in at least two of the populations (M.S. Jones and D.E. Green, unpublished data; Muths et al., 2003). Boreal toads are now absent throughout large areas of their former distribution in Colorado and southern Wyoming and may be extinct in New Mexico (Corn et al., 1989; Carey, 1993; Stuart and Painter, 1994). These toads are classified as “endangered” by Colorado and New Mexico and are designated as a protected non-game species in Wyoming. The U.S. Fish and Wildlife Service has categorized the Southern Rocky Mountain populations for federal listing and is currently reviewing their designation as a “warranted but precluded” species for possible listing in the next few years. For the management of boreal toads and their habitats, a Boreal Toad Recovery Team was formed by the Colorado Division of Wildlife in 1995 as part of a collaborative effort with federal agencies within the United States’ departments of the Interior and Agriculture and with agencies in two adjoining states. To date, conservation agreements have been signed by eight state and federal agencies and by the Colorado Natural Heritage Program. Although boreal toads were considered common throughout their range in Colorado, no comprehensive surveys of the numbers and sizes of their populations were conducted prior to mass die-offs in the 1970s. Surveys completed in the late 1980s to

  8. Assessment of the performance of a conceptual acoustic surveillance system for anomalous events in LMFBRs

    Doolittle, R.D.; Carey, W.M.

    1977-01-01

    A method is developed for calculating the detectability of anomalous acoustic events. The example used is the sodium vapor bubble collapse in the subcooled regions of a Liquid Metal Fast Breeder Reactor (LMFBR). This method provides a range of estimates for detection and false alarm probabilities in acoustic surveillance systems for sodium boiling and voiding detection, as well as any other impulsive events such as loose-parts monitoring. The signal excess at the receiver array from an impulsive source is computed by an extension of methods introduced by W. Carey. Assuming an exponential pulse form for the signal (or its envelope) the equivalent source level is determined from the energy flux spectral density for inclusion in the sonar equation. The signal excess (SE) is then given by the source level (SL) minus the noise level (NL) minus the transmission loss (TL) minus the detection threshold (DT) plus the receiving array gain

    Thirteen per cent of all corneas harvested by the Eye Bank of South Australia during 1986 were discarded because storage time in McCarey-Kaufman medium exceeded four days. We have therefore examined the suitability of the Dutch method of long-term corneal storage for our purposes. Twenty-two human corneas that had been discarded from the Eye Bank were assessed using the trypan blue-sucrose staining technique, and then placed into long-term storage for 15 to 17 days. They were then reassessed by vital dye staining before permanent flat-mounts were prepared for silver staining of the endothelium. A good correlation (albeit subjective) was found between the non-destructive and destructive techniques of endothelial cell assessment. Those corneas that failed to survive organ culture storage were easily detected. The Dutch system of corneal preservation and post-storage assessment seems well-suited to Australian eye-banking.

    We present observations at 3.6 and 4.5 microns using IRAC on the Spitzer Space Telescope of a set of main sequence A stars and white dwarfs that are potential calibrators across the JWST instrument suite. The stars range from brightnesses of 4.4 to 15 mag in K band. The calibration observations use a similar redundancy to the observing strategy for the IRAC primary calibrators (Reach et al. 2005) and the photometry is obtained using identical methods and instrumental photometric corrections as those applied to the IRAC primary calibrators (Carey et al. 2009). The resulting photometry is then compared to the predictions based on spectra from the CALSPEC Calibration Database (http://www.stsci.edu/hst/observatory/crds/calspec.html) and the IRAC bandpasses. These observations are part of an ongoing collaboration between IPAC and STScI investigating absolute calibration in the infrared.

    This is the second report of musicogenic epilepsy in Japan. A 23-year-old woman was admitted to our hospital due to the musicogenic epilepsy. She had four generalized tonic clonic seizures at 18 and 19 years old. Since 19, she had had complex partial seizures lasting for about 20 seconds which was easily evoked by listening to an American pops particularly "Dreamlover" song by Mariah Carey. Brian MRI and interictal 99mTc HMPAO-SPECT showed no abnormalities. In the ictal EEG recording, three minutes after listening to the song, seizure activities were recorded from the right temporal region with 11Hz rhythmic epileptiform activities over the right temporal region and subsequent delta activities over the right hemisphere. The song that induced the seizure had a specific meaning that might evoke her emotion as had been pointed out in the previous reports.

    Concentrations of 90 Sr and 137 Cs in Carey's balsamroot (Balsamorhiza careyana) and Gray's desert parsley (Lomatium grayi) were similar to concentrations observed in other plants collected on the Hanford Site and from offsite locations surrounding the Site as part of annual Hanford Site surveillance. Observed concentrations may be attributed to historic fallout more than to Hanford Site emissions, although the observation that 200 Area plants had slightly higher concentrations of 137 Cs than 100 Area plants is consistent with other monitoring data of radioactivity in soil and vegetation collected onsite. The present concentrations of 90 Sr and 137 Cs in balsamroot and parsley fluctuate around background levels with some of the higher observed concentrations of 90 Sr found on the Fitzner/Eberhardt Arid Lands Ecology (ALE) Reserve.

Convenience sampling technique was used in selecting the three content, computer and educational technology experts to validate the web-based courseware. Non-randomized and non-equivalent Junior secondary school students from two schools were used for field trial validation. Four validating instruments were employed in conducting this study: (i Content Validation Assessment Report (CVAR; (ii Computer Expert Validation Assessment Report (CEAR; (iii Educational Technology Experts Validation Assessment Report (ETEVAR; and (iv Students Validation Questionnaire (SVQ. All the instruments were face and content validated. SVQ was pilot tested and reliability coefficient of 0.85 was obtained using Cronbach Alpha. CVAR, CEAR, ETEVAR were administered on content specialists, computer experts, and educational technology experts, while SVQ was administered on 83 JSS students from two selected secondary schools in Minna. The findings revealed that the process of developing web-based courseware using Dick and Carey Instructional System Design was successful. In addition, the report from the validating team revealed that the web-based courseware is valuable for learning basic technology. It is therefore recommended that web-based courseware should be produced to teach basic technology concepts on large scale.

    Full Text Available The paper analyzes the ideas put forward by Shugart and Carey (1992 and Mainwaring and Shugart (1997 regarding the combined effect of presidential electoral systems and the timing of the parliamentary elections over political representation and governability. The hypotheses of these authors are contrasted with the results of Latin American presidential elections (1996-2000. The conclusion is reached that, as expected, the timing of presidential and parliamentary elections and the electoral system for president tend to influence the chance that the party or coalition of the president has a sizeable or majority parliamentary representation.El trabajo analiza los planteamientos desarrollados por Shugart y Carey (1992 y Mainwaring y Shugart (1997 con relación al efecto que sobre la gobernabilidad y la representatividad tienen las distintas combinaciones de sistema electoral para presidente de la República con la fecha en que se realizan las elecciones legislativas (simultáneas o separadas con las presidenciales, confrontando las hipótesis que se derivan de estos análisis con los resultados de las elecciones presidenciales celebradas en los países de América Latina entre 1996 y 2000. Se llega a la conclusión de que los resultados electorales tienden a corroborar las hipótesis sobre el efecto combinado del calendario electoral y el sistema electoral presidencial sobre la gobernabilidad y la representatividad, y en particular sobre la posibilidad de que el presidente electo cuente con una fuerza parlamentaria mayoritaria o sólida.

    Full Text Available The paper “Navigating the process of ethical approval” (Carey, 2010 raises many issues about the influence Institutional Ethics Committees have on research methodology and what can or cannot take place in research. Carey draws attention to the ethical challenges classic grounded theory researchers face when an ethical proposal that follows the principles of the methodology is presented to an Ethics Committee, whose main responsibility is the protection of participants. Ethics committees not only guide researchers on acceptable ethical practice, but are charged with monitoring ethical standards and ensuring researchers act in accordance with professional expectations for researchers within the jurisdiction. These committees aim to ensure consistency of ethical practice in research. While there is generally some flexibility in the review process researchers often find ethical requirements constraining, as guidelines are primarily prescriptive and are designed to ensure consistency in the application of universal ethical principles in research. In New Zealand, consistency includes paying attention to broader socio-cultural responsibilities to society that includes promoting awareness of the Code of Health and Disability Services Consumer Rights 1996, the Health Information Privacy Code 1994, and promoting ethical practices which involve Maori (the local indigenous people in research proposals as much as possible (Ministry of Health, 2006. So while researchers in training assume that their prime interest concerns the management of a research topic and methodology, they quickly find out that ethical guidelines influence research design. Even though there is an international code of ethics (Universal Declaration of Human Rights, 2005 that defines ethical standards for researchers around the world, each country has its own specific requirements depending on the context. In this paper, ethical drivers in the New Zealand context are outlined and

    Climate change research has largely focused on the biophysical, economic, and political aspects of the phenomenon, its projected impacts, and the possibilities for adaptation (Carey et al. 2014; Castree et al. 2014). In the classroom, too, climate change is generally presented as a scientific, technological, political, and economic challenge. However, defining climate change as physical challenge, divorced from its cultural causes and responses, forecloses some pathways of inquiry and limits the possibilities for adaptation (Adger et al. 2013). Recent perspectives by the environmental historian Mark Carey and colleagues (2014) and by the geographer Noel Castree and colleagues (2014) contend that ethnographic, narrative, social scientific, and humanistic insights are necessary additions to the climate change policy process and can contribute to deliberate, resilient responses to climate change. Among the humanistic insights needed are strategies and practices to maintain fortitude and persistence in the midst of dispiriting ecological trends. Students facing the "gloom and doom" of climate change data in environmental studies courses can experience negative states of mind such as denial, despair, burnout, and grief. Emerging research, however, demonstrates how contemplative practice can shift consciousness and promote resilience. Contemplative practices are those that consciously direct calm, focused attention. Such practices can build internal resilience, by promoting a greater sense of calm and well-being, decreasing stress, and sharpening focus and concentration. In addition, contemplative practices improve relationships with other people, through increasing compassion and flexibility in thinking. They also strengthen relationships with the surrounding world by increasing our ability to question, explore, and cope with rapid change and complexity. This presentation provides a context for incorporating contemplative practices, including mindfulness exercises

    According to the Ministry of Education Korea (2014), the approximately 70.4% of all students with disabilities are included in general schools in Korea. However, studies show that Korean GPE teachers do not feel comforatble or prepared to include students with disabilities (Oh & Lee, 1999; Roh, 2002; Roh & Oh, 2005). The purpose of this study was to explore whether an APE e-learning supplement would have an impact on the level of self-efficacy and content knowledge of pre-service teachers related to including students with intellectual disabilities. An APE supplement was developed based on the Instructional Design Model (Dick, Carey, & Carey, 2005) to provide three sources of self-efficacy, mastery experience, vicarious experience, and social persuasions. Three groups of pre-service teachers (N=75) took the same content supplement with different delivery system, E-learning group (n=25) with online, traditional group (n=25) with printed handout, and control group (n=25) without supplement. Two instruments, the Physical Educators' Situation-Specific Self-efficacy and Inclusion Student with Disabilities in Physical Education (SE-PETE-D) and the content knowledge test, were given to all participants twice (i.e., pretest and posttest). A 3×2 mixed effect ANOVA revealed that pre-service teachers' perceived self-efficacy (p=0.023) improved after taking the e-learning supplement. However, there was no significant difference in the level of content knowledge (p=0.248) between the learning group and tranditional group. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Little is known about the effects of jaguars on the population of marine turtles nesting in Tortuguero National Park, Costa Rica. This study assessed jaguar predation impact on three species of marine turtles (Chelonia mydas, Dermochelys coriáceaand Eretmochelys imbricatathat nest in Tortuguero beach. Jaguar predation data was obtained by using two methodologies, literature review (historical records prior the year 2005 and weekly surveys along the 29 km stretch of beach during the period 2005-2013. Our results indicated that jaguar predation has increased from one marine turtle in 1981 to 198 in 2013. Jaguars consumed annually an average of 120 (SD= 45 and 2 (SD= 3 green turtles and leatherbacks in Tortuguero beach, respectively. Based on our results we concluded that jaguars do not represent a threat to the population of green turtles that nest in Tortuguero beach, and it is not the main cause for population decline for leatherbacks and hawksbills. Future research should focus on continuing to monitor this predator-prey relationship as well as the factors that influence it so the proper management decisions can be taken.

    Background Airborne allergens vary from one climatic region to another. Therefore, it is important to analyze the environment of the region to select the most prevalent allergens for the diagnosis and treatment of allergic patients. Objective To evaluate the prevalence of positive skin tests to pollen and fungal allergens collected from local indigenous plants or isolated molds, as well as other outdoor and indoor allergens in allergic patients in 6 different geographical areas in the Kingdom of Saudi Arabia (KSA), the United Arab Emirates, and Sudan. Materials and methods Four hundred ninety-two consecutive patients evaluated at different Allergy Clinics (276 women and 256 men; mean age, 30 years) participated in this study. The selection of indigenous allergens was based on research findings in different areas from Riyadh and adjoining areas. Indigenous raw material for pollen grains was collected from the desert near the capital city of Riyadh, KSA. The following plants were included: Chenopodium murale, Salsola imbricata, Rumex vesicarius, Ricinus communis, Artiplex nummularia, Amaranthus viridis, Artemisia monosperma, Plantago boissieri, and Prosopis juliflora. Indigenous molds were isolated from air sampling in Riyadh and grown to obtain the raw material. These included the following: Ulocladium spp., Penicillium spp., Aspergillus fumigatus, Cladosporium spp., and Alternaria spp. The raw material was processed under Good Manufacturing Practices for skin testing. Other commercially available outdoor (grass and tree pollens) and indoor (mites, cockroach, and cat dander) allergens were also tested. Results The highest sensitization to indigenous pollens was detected to C. murale (32%) in Khartoum (Sudan) and S. imbricata (30%) and P. juliflora (24%) in the Riyadh region. The highest sensitization to molds was detected in Khartoum, especially to Cladosporium spp. (42%), Aspergillus (40%), and Alternaria spp. (38%). Sensitization to mites was also very prevalent

    Ionizing radiation induces DNA damage and are harmful to mankind. They act through free radical generation, which target the double bonds of all cellular macromolecules. The radiation damage may be classified as probabilistic or deterministic, depending on the dose of radiation exposure. Since radiation affects multiple organs so those drugs which protect many organs, would be more beneficial. In this process herbal extracts, which are cocktail of several phyto-chemicals, would be more promising. Initially sulphur containing bio-molecules were identified as radio-protector, but now many secondary metabolites from plant kingdom, have been reported to be radio-protective. They have different mechanism of action, but most of them either prevent the FR induced DNA damage or accelerate the DNA repair process. Aminofostine, WR-2721, 159243, 2926 are some of the examples. However they have limited use because of associated cytotoxicity. Eicosanoids, topoisornerase inhibitors (e.g. camptothecin, topotecan), and the hypoxia-activated anthraquinone AQ4N have shown radioprotecting potential. Several plant products, derived from Tulsi, Vinca alkaloids, taxans, turmeric, Rubia cordifolia, Semecarpus anacardium and several plants rich in polyphenols and flavones have shown hemotherapeutic potential. Similarly, Hippophae, rhodiola imbricata, Podophyllum hexandrum, Ocimum sancturn, Plumbago zeylanica etc have shown radioprotection. Rubia cordifolia has shown both chemotherapeutic and radioprotective property in rats and A-431 cells. Similarly Semecarpus anacardium extract has shown cell cycle arrest in DU-145 cells. (author)

    Full Text Available Synchrotron radiation X-ray tomographic microscopy (SRXTM is a non-destructive technique for the investigation and visualization of the internal features of solid opaque objects, which allows reconstruction of a complete three-dimensional image of internal structures by recording of the differences in the effects on the passage of waves of energy reacting with those structures. Contrary to X-rays, produced in a conventional X-ray tube, the intense synchrotron light beams are sharply focused like a laser beam. We report encouraging results from the use of SRXTM for purely taxonomic purposes in brachiopods: an attempt to find a non-destructive and more efficient alternative to serial sectioning and several other methods of dissection together with the non-destructive method of X-ray computerised micro-tomography. Two brachiopod samples were investigated using SRXTM. In “Rhynchonella” flustracea it was possible to visualise the 3D shape of the crura and dental plates. In Terebratulina imbricata it was possible to reveal the form of the brachidium. It is encouraging that we have obtained such promising results using SRXTM with our very first two fortuitous samples, which had respectively fine-grained limestone and marl as infilling sediment, in contrast to the discouraging results communicated to us by some colleagues who have tested specimens with such infillings using X-ray micro-tomography. In future the holotypes, rare museum specimens or delicate Recent material may be preferentially subjected to this mode of analysis.

    Polynoid scale worms (Polynoidae, Annelida) invaded deep-sea chemosynthesis-based ecosystems approximately 60 million years ago, but little is known about their genetic adaptation to the extreme deep-sea environment. In this study, we reported the first two transcriptomes of deep-sea polynoids (Branchipolynoe pettiboneae, Lepidonotopodium sp.) and compared them with the transcriptome of a shallow-water polynoid (Harmothoe imbricata). We determined codon and amino acid usage, positive selected genes, highly expressed genes and putative duplicated genes. Transcriptome assembly produced 98,806 to 225,709 contigs in the three species. There were more positively charged amino acids (i.e., histidine and arginine) and less negatively charged amino acids (i.e., aspartic acid and glutamic acid) in the deep-sea species. There were 120 genes showing clear evidence of positive selection. Among the 10% most highly expressed genes, there were more hemoglobin genes with high expression levels in both deep-sea species. The duplicated genes related to DNA recombination and metabolism, and gene expression were only enriched in deep-sea species. Deep-sea scale worms adopted two strategies of adaptation to hypoxia in the chemosynthesis-based habitats (i.e., rapid evolution of tetra-domain hemoglobin in Branchipolynoe or high expression of single-domain hemoglobin in Lepidonotopodium sp.).

    Full Text Available Meladema Laporte, 1835 are relatively large, stream-dwelling diving beetles, distributed widely in the Western Palaearctic, from the Atlantic Islands to Turkey, and from southern France and the Balkans to the central Sahara. In addition to the three previously recognised taxa (M. coriacea Laporte, 1835, M. imbricata (Wollaston, 1871 and M. lanio (Fabricius, 1775 we describe a new, cryptic, species from the central Mediterranean area, which can be distinguished from M. coriacea on both DNA sequence data and morphology, and provide a key to known species of the genus. Based on the study of genotyped material, both recent and archival, as well as the examination of a large number of museum specimens, we show that M. lepidoptera sp. n. occurs to the apparent exclusion of M. coriacea on Corsica, Sardinia and islands of the Tuscan Archipelago, but that both taxa are found in peninsular Italy, where they may occasionally hybridize. In the absence of the original type series, we designate a neotype for M. coriacea, and take the opportunity to designate a lectotype for M. lanio. Morphological variation in Meladema species is discussed, including that seen in known and presumed hybrids. Our study highlights the incomplete state of knowledge of Mediterranean biodiversity, even in relatively large, supposedly well-studied taxa.

    This article describes biological hydrogen production from diary wastewater via anaerobic fermentation using pretreated heat shock (100 degrees Celsius, 30 min.) and acid (pH 3.0, 24 h) treatment procedures to selectively enrich the hydrogen producing mixed consortia prior to inoculation to batch reactors. Bioreactor used for immobilization consortia was operated at mesophilic (room) temperature (20{+-}3 degrees Celsius), under acidophilic conditions (pH 4.0-4.5), HRT (2h), and a natural support for generate hydrogen producing mixed consortia biofilm: Opuntia imbricata. Reactor was initially operated with sorbitol (5g/L) for 60 days of operation. Batch tests were conducted using 20{+-}0.02g of natural support with biofilm. Batch experiments were conducted to investigate the effect of COD (2.9-21.1 g-COD/L), at initial pH of 7.0, 32{+-}1 degrees Celsius. Maximum hydrogen yield was obtained at 21.1 g-COD/L. Experiments of pH effect were conducted using the optimal substrate concentration (21.2 g-COD/L), at pH 4 to 7 and 11.32 (pH diary wastewater) ,and 32{+-}1 degrees Celsius. Experiments results indicate the optimum initial cultivation was pH 4.0, but we can consider also a stable hydrogen production at pH 11.32 (pH diary wastewater), so we can avoid to fit the pH, and use diary wastewater as it left the process of cheese manufacture. The operational pH of 4.0 is 1.5 units below that of previously reported hydrogen producing organisms. The influence of the effect of temperature were conducted using the optimal substrate concentration (21.2 g-COD/L), two pH levels: 4.0 and 11.32, and four different temperatures: 16{+-}3 degrees Celsius (room temperature), 3 C, 45{+-}1 degrees Celsius y 55{+-}1 degrees Celsius.Optimal temperature for hydrogen production from diary wastewater at pH 4.0 was 55{+-}1 degrees Celsius, and for pH 11.32 was 16{+-}3 degrees Celsius.Therefore, the results suggests biofilm reactors in a natural support like Opuntia imbricata have good potential

  12. Herbivore-mediated ecological costs of reproduction shape the life history of an iteroparous plant.

    Plant reproduction yields immediate fitness benefits but can be costly in terms of survival, growth, and future fecundity. Life-history theory posits that reproductive strategies are shaped by trade-offs between current and future fitness that result from these direct costs of reproduction. Plant reproduction may also incur indirect ecological costs if it increases susceptibility to herbivores. Yet ecological costs of reproduction have received little empirical attention and remain poorly integrated into life-history theory. Here, we provide evidence for herbivore-mediated ecological costs of reproduction, and we develop theory to examine how these costs influence plant life-history strategies. Field experiments with an iteroparous cactus (Opuntia imbricata) indicated that greater reproductive effort (proportion of meristems allocated to reproduction) led to greater attack by a cactus-feeding insect (Narnia pallidicornis) and that damage by this herbivore reduced reproductive success. A dynamic programming model predicted strongly divergent optimal reproductive strategies when ecological costs were included, compared with when these costs were ignored. Meristem allocation by cacti in the field matched the optimal strategy expected under ecological costs of reproduction. The results indicate that plant reproductive allocation can strongly influence the intensity of interactions with herbivores and that associated ecological costs can play an important selective role in the evolution of plant life histories.

    Life-history theory suggests that iteroparous plants should be flexible in their allocation of resources toward growth and reproduction. Such plasticity could have consequences for herbivores that prefer or specialize on vegetative versus reproductive structures. To test this prediction, we studied the response of the cactus bug (Narnia pallidicornis) to meristem allocation by tree cholla cactus (Opuntia imbricata). We evaluated the explanatory power of demographic models that incorporated variation in cactus relative reproductive effort (RRE; the proportion of meristems allocated toward reproduction). Field data provided strong support for a single model that defined herbivore fecundity as a time-varying, increasing function of host RRE. High-RRE plants were predicted to support larger insect populations, and this effect was strongest late in the season. Independent field data provided strong support for these qualitative predictions and suggested that plant allocation effects extend across temporal and spatial scales. Specifically, late-season insect abundance was positively associated with interannual changes in cactus RRE over 3 years. Spatial variation in insect abundance was correlated with variation in RRE among five cactus populations across New Mexico. We conclude that plant allocation can be a critical component of resource quality for insect herbivores and, thus, an important mechanism underlying variation in herbivore abundance across time and space.

  14. Demographic models reveal the shape of density dependence for a specialist insect herbivore on variable host plants.

    1. It is widely accepted that density-dependent processes play an important role in most natural populations. However, persistent challenges in our understanding of density-dependent population dynamics include evaluating the shape of the relationship between density and demographic rates (linear, concave, convex), and identifying extrinsic factors that can mediate this relationship. 2. I studied the population dynamics of the cactus bug Narnia pallidicornis on host plants (Opuntia imbricata) that varied naturally in relative reproductive effort (RRE, the proportion of meristems allocated to reproduction), an important plant quality trait. I manipulated per-plant cactus bug densities, quantified subsequent dynamics, and fit stage-structured models to the experimental data to ask if and how density influences demographic parameters. 3. In the field experiment, I found that populations with variable starting densities quickly converged upon similar growth trajectories. In the model-fitting analyses, the data strongly supported a model that defined the juvenile cactus bug retention parameter (joint probability of surviving and not dispersing) as a nonlinear decreasing function of density. The estimated shape of this relationship shifted from concave to convex with increasing host-plant RRE. 4. The results demonstrate that host-plant traits are critical sources of variation in the strength and shape of density dependence in insects, and highlight the utility of integrated experimental-theoretical approaches for identifying processes underlying patterns of change in natural populations.

    To investigate the expulsion of radiotransmitters in snakes and modify the surgical technique for coelomic implantation to prevent its occurrence. To enable monitoring of snakes for an ecological study, radiotransmitters were implanted in 23 south-west carpet pythons (Morelia spilota imbricata) using the standard surgical technique. In a further 23 pythons we used a refinement of the technique, which anchored the tracking device, using non-dissolvable sutures, to the snake's rib-cage. We also investigated the potential mechanisms for expelling the radiotransmitters in one snake that underwent an exploratory coeliotomy. Of the initial group of snakes, 12 (52%) expelled the radiotransmitter between 4 days and 3 years post implantation. In the later group, which underwent the refined technique of implantation, none of the radiotransmitters was expelled and no adverse responses were observed. An appropriately sized radiotransmitter anchored to the rib-cage of the snake will prevent expulsion of the device and appears to be well tolerated. Non-attachment of the tracking device enables it to migrate along the length of the body, particularly during feeding and reproduction. Caudal positioning of the transmitter's antenna provides a possible pathogenesis for expulsion into the cloaca. © 2010 The Authors.

    Full Text Available Taking (inauthenticity as his subject and intertextuality as the structuring principle, Peter Carey brings together Australian literary and social history, literary theory and a self-reflexive probe into the issues of identity, authenticity and cultural insecurity of a postcolonial society. The novel is interpreted as an allegorical account of national history and an allegorical narrative on the theoretical matters of originality and authorship.Keywords: Carey, identity, (inauthenticity, intertextuality, text, postcolonialism. The most well-known Australian author today, Peter Carey, has more than once found inspiration for his novels in already existing texts of British and Australian cultures. The most notable examples are his sixth novel titled Jack Maggs, his seventh novel titled True History of the Kelly Gang and the one explored in this paper, his eighth novel titled My Life as a Fake. Carey’s Jack Maggs (1997 retells the story of Dickens’ Great Expectations and in a postcolonial fashion of re-writing imperial texts gives voice to the previously marginalised point of view so that the story is told from the perspective of the runaway convict, Magwitch. The Booker Prize winning True History of the Kelly Gang (2001 is inspired by the so-called “Jerilderie letter,” which was written by Australia’s most famous outlaw, Ned Kelly, after a bank robbery in 1879. The fifty-six page long original letter is expanded in Carey’s version into thirteen parcels which actually make up this epistolary novel. My Life as a Fake (2003 is a roman a clef based on the literary hoax which took place in Melbourne in 1944 and assumed an Ossianic significance in the Australian literary establishment. Wishing to explore the depths of degradation which, in their opinion, Australian modernist poetry had reached, two young disgruntled poets, Harold Stewart and James McAuley, conjured up a fictitious poet, Ern Malley, a mechanic and the author of The Darkening

    Poor achievement of students' performance on Chemistry may result from unfavourable learning processes. Therefore, innovation on learning process must be created. Regarding fast development of mobile technology, learning process cannot ignore the crucial role of the technology. This research and development (R&D) studies was done to develop android based application and to study the effect of its integration in Learning together (LT) into the improvement of students' learning creativity and cognitive achievement. The development of the application was carried out by adapting Borg & Gall and Dick & Carey model. The developed-product was reviewed by chemist, learning media practitioners, peer reviewers, and educators. After the revision based on the reviews, the application was used in the LT model on the topic of Stoichiometry in a senior high school. The instruments were questionnaires to get comments and suggestion from the reviewers about the application, and the another questionnaire was to collect the data of learning creativity. Another instrument used was a set of test by which data of students' achievement was collected. The results showed that the use of the mobile based application on Learning Together can bring about significant improvement of students' performance including creativity and cognitive achievement.

  4. Secondary cosmic-ray e+- from 1 to 100 GeV in the upper atmosphere and interstellar space, and interpretation of a recent e+ flux measurement

    1976-01-01

    Secondary fluxes of cosmic-ray e from the decay of mesons produced by nuclear interactions are calculated for depths under 10 g cm -2 of atmosphere or interstellar space for energies from 1 to 100 GeV. Secondary meson spectra applicable for energies > or =5 GeV are obtained from the recently measured spectra of Carey et al. using Monte Carlo techniques. An analytic model is presented which identifies all essential parameters and enables easy calculation of efluxes for various parameter values. This model is used to interpret the e + measurement of Buffington, Orth, and Smoot. We find the mean thickness of interstellar and source material to be 4.3 (+1.8,-1.2) g cm -2 for cosmic-ray e + above 4 GeV. This result is difficult to reconcile with the recently proposed two-containment-volume propagation models of Cowsik and Wilson; Rengarajan, Stephens, and Verma; and Meneguzzi: all of the models predict a result near 1.8 g cm -2 at these energies due to the energy dependence of the measured (Li+Be+B)/(C+O) ratio. Single-containment-volume (galactic) models invoking an energy-dependent leakage lifetime are compatible with the e + data, but lack a mechanism to explain the energy dependence

    Knowledge is empowering in all settings, but plays an elevated role in empowering under-represented groups in field research. Field research, particularly polar field research, has deep roots in masculinized and colonial traditions, which can lead to high barriers for women and minorities (e.g. Carey et al., 2016). While recruitment of underrepresented groups into polar field research has improved through the efforts of organizations like the Association of Polar Early Career Scientists (APECS), the experiences and successes of these participants is often contingent on the availability of specialized training opportunities or the quality of explicitly documented information about how to survive Arctic conditions or how to establish successful measurement protocols in harsh environments. In Arctic field research, knowledge is often not explicitly documented or conveyed, but learned through "experience" or informally through ad hoc advice. The advancement of field training programs and knowledge management systems suggest two means for unleashing more explicit forms of knowledge about field work. Examples will be presented along with a case for how they level the playing field and improve the experience of field work for all participants.

    Full Text Available The way of teaching and learning traditional crafts have always used traditional apprenticeship learning methods where the expert facilitates transfer of practice skill sets to novices. As a craft has been taught in conventional approach, the students and experts have been facing several problems especially when expert needs to teach a group of students. An appropriate mapping of craft education and Information and Communication Technologies using Multimedia technology for instance, has the potential in transforming traditional craft learning into more flexible environment. This paper reports on a research project on development of an interactive multimedia courseware package for teaching and learning traditional craft called e-CRAFT. The e-CRAFT is specially designed for songket weaving course taught to certificate and diploma students from Fakulti Seni Kraf Tenunan in their first year study at Institut Kraf Negara, Malaysia (National Craft Institute. The courseware was developed in a web-based environment and overall development process was based on the Dick and Carey's process model and conceptual Instructional Design framework. It is made up of eight learning modules: Introduction, Materials & Tools, Knowing Motifs, Learn How to Weave, Quizzes & Test, Online Discussion, Glossary and Help module. In order to test whether the courseware is suitable in terms of usability, pilot testing was done to a sample of 10 students. The results from pilot test received positive feedback which signifies the courseware is considered acceptable for effectiveness study and help for further improve of the e-CRAFT courseware.

Slovenia, the most developed republic of former Yugoslavia, became an EU member in May 2004. In 1991, after its independence from Yugoslavia, Slovenia’s transition to a free market economy resulted in lost jobs and an unemployment rate of 12%. In 1999, as the Institute for Symbolic Analysis and Development of Information Technologies, located in Velenje, Slovenia, we decided to offer several online courses to help unemployed people gain the skills and knowledge needed for employability in information technology. We drew on our previous experience teaching online courses at Sarajevo University after the Bosnian war and on the experience of West Valley College from Saratoga, Silicon Valley in e-Learning. Over the last four years, we organized and delivered e-Learning courses in digital media design and production, with good results. Several students found jobs and changed their perception and attitude as they became more self-confident. We believe e-Learning can efficiently enhance lifelong learning and support economic development, especially in new member countries transitioning from former socialistic to free market economies.

    Full Text Available This study aims to examine various aspects of religiosity in members of the Neocatechumenal Way and the Catholic Charismatic Renewal. First, we assigned intergroup differences in Emotions toward God, Religious Comfort and Strain and Religious Attributions. Next, we estimated the net effects of Emotions toward God, Religious Comfort and Strain and Religious Attributions on religiosity. One hundred fifty–five people participated in the research, 81 members of the Catholic Charismatic Renewal and 74 members of the Neocatechumenal Way. We applied the Religious Comfort and Strain Scale by Yali, Exline, Wood, and Worthington, the Emotions toward God Scale by Huber and the Religious Attributions Scale by Exline, Park, Smyth and Carey. The results suggest that members of the Neocatechumenal Way do not differ from the Catholic Charismatic Renewal’s members in Religious Comfort and Positive Emotions toward God. However, the members of the Neocatechumenal Way scored higher in Religious Strain. A moderating effect of the religious movement on the relation between Fear of God and religiosity was observed.

    Maternal antenatal mood is associated with negative infant temperament. This link has not been substantiated in Asian populations. We evaluated the association between antenatal maternal mood and infant temperament among Asian mother-infant pairs. Antenatal maternal depression and anxiety were assessed using the Edinburgh Postnatal Depression Scale (J. Cox, J. Holden, & R. Sagovsky, 1987) and the State-Trait Anxiety Inventory (C. Spielberger, R. Gorsuch, R. Lushene, P. Vagg, & G. Jacobs, 1983), respectively, at 26 weeks of pregnancy and 3 months' postnatally. Infant temperament was evaluated with the Early Infant Temperament Questionnaire (B. Medoff-Cooper, W.B. Carey, & S.C. McDevitt, 1993) at 3 months. Factor analysis was performed to extract culturally relevant categories of temperamental traits. Linear regression was performed to examine the influences of antenatal maternal mood on the factor-model-derived infant temperament. Of the 609 mothers, 11% met risk criteria for depression, 17% for state-anxiety, and 19% for trait-anxiety during pregnancy. Factor analysis yielded three infant temperament factors: Emotionality and Attentional Regulation, Sensory Reactivity, and Regularity and Motor Expression, Cronbach's αs = 0.613, 0.712, and 0.752, respectively. Maternal antenatal state-anxiety, p emotionality and poor attentional regulation, especially among Chinese, whereas depression was not, p = .090.

    Hurricane Sandy in late October 2012 drove before it a storm surge that rose to 4.28 meters above mean lower low water at The Battery in lower Manhattan, and flooded the Hugh L. Carey automobile tunnel between Brooklyn and The Battery. This study examines the surge event in New York Harbor using the Weather Research and Forecasting (WRF) atmospheric model and the Coupled-Ocean-Atmosphere-Wave- Sediment Transport/Regional Ocean Modeling System (COAWST/ROMS). We present a new technique using directional analysis to calculate and display maps of a coastline's potential for storm surge; these maps are constructed from wind fields blowing from eight fixed compass directions. This analysis approximates the surge observed during Hurricane Sandy. The directional analysis is then applied to surge events at Charleston, South Carolina, New Orleans, Louisiana, and Tacloban City, the Philippines. Emergency managers could use these directional maps to prepare their cities for an approaching storm, on planning horizons from days to years.

    Full Text Available Omphalocele can be associated with single gene disorders, neural tube defects, diaphragmatic defects, fetal valproate syndrome, and syndromes of unknown etiology. This article provides a comprehensive review of omphalocele-related disorders: otopalatodigital syndrome type II; Melnick–Needles syndrome; Rieger syndrome; neural tube defects; Meckel syndrome; Shprintzen–Goldberg omphalocele syndrome; lethal omphalocele-cleft palate syndrome; cerebro-costo-mandibular syndrome; fetal valproate syndrome; Marshall–Smith syndrome; fibrochondrogenesis; hydrolethalus syndrome; Fryns syndrome; omphalocele, diaphragmatic defects, radial anomalies and various internal malformations; diaphragmatic defects, limb deficiencies and ossification defects of skull; Donnai–Barrow syndrome; CHARGE syndrome; Goltz syndrome; Carpenter syndrome; Toriello–Carey syndrome; familial omphalocele; Cornelia de Lange syndrome; C syndrome; Elejalde syndrome; Malpuech syndrome; cervical ribs, Sprengel anomaly, anal atresia and urethral obstruction; hydrocephalus with associated malformations; Kennerknecht syndrome; lymphedema, atrial septal defect and facial changes; and craniosynostosis- mental retardation syndrome of Lin and Gettig. Perinatal identification of omphalocele should alert one to the possibility of omphalocele-related disorders and familial inheritance and prompt a thorough genetic counseling for these disorders.

  17. Violent Adolescent Planet Caught Infrared Handed

    The prevailing view of planet formation depicts accumulation of progressively larger objects, culminating in accretionary impacts between Moon- to Mars-sized protoplanets. Cosmochemists have found evidence in chondritic meteorites for such violent events, and the Moon is thought to have involved a huge impact between a Mars-sized object and the still-growing proto-Earth. Now we may have evidence for a large impact during planet formation around another star. Carey Lisse (Applied Physics Lab of the Johns Hopkins University, Baltimore) and colleagues from the Space Telescope Science Institute (Baltimore), the University of Cambridge (UK), the Open University (Milton Keyes, UK), the University of Georgia (Athens, GA), Jet Propulsion Lab (Pasadena, CA), and the University of Rochester (New York) analyzed infrared spectra obtained by the Spitzer Space Telescope. They found a prominent peak in the spectrum at 9.3 micrometers, and two smaller ones at slightly lower and higher wavelengths. These peaks are consistent with the presence of SiO gas, a product expected to be produced by a highly energetic impact. The spectral measurements also allowed Lisse and his colleagues to estimate the size of the dust and they found that there is an abundance of micrometer-sized dust grains. This argues for a fresh source of fine material during the past 0.1 million years. That source may have been an impact between two protoplanets surrounding this young star.

    PurposeTo describe our experience with a large cohort (411 patients from 288 families) of various forms of skeletal dysplasia who were molecularly characterized.MethodsDetailed phenotyping and next-generation sequencing (panel and exome).ResultsOur analysis revealed 224 pathogenic/likely pathogenic variants (54 (24%) of which are novel) in 123 genes with established or tentative links to skeletal dysplasia. In addition, we propose 5 genes as candidate disease genes with suggestive biological links (WNT3A, SUCO, RIN1, DIP2C, and PAN2). Phenotypically, we note that our cohort spans 36 established phenotypic categories by the International Skeletal Dysplasia Nosology, as well as 18 novel skeletal dysplasia phenotypes that could not be classified under these categories, e.g., the novel C3orf17-related skeletal dysplasia. We also describe novel phenotypic aspects of well-known disease genes, e.g., PGAP3-related Toriello-Carey syndrome-like phenotype. We note a strong founder effect for many genes in our cohort, which allowed us to calculate a minimum disease burden for the autosomal recessive forms of skeletal dysplasia in our population (7.16E-04), which is much higher than the global average.ConclusionBy expanding the phenotypic, allelic, and locus heterogeneity of skeletal dysplasia in humans, we hope our study will improve the diagnostic rate of patients with these conditions.GENETICS in MEDICINE advance online publication, 5 April 2018; doi:10.1038/gim.2018.50.

    Carey and Friel suggest that we turn to knowledge developed in the field of public administration, especially new public governance, to better understand the process of implementing health in all policies (HiAP). In this commentary, I claim that theories from the policy studies bring a broader view of the policy process, complementary to that of new public governance. Drawing on the policy studies, I argue that time and ideas matter to HiAP implementation, alongside with interests and institutions. Implementing HiAP is a complex process considering that it requires the involvement and coordination of several policy sectors, each with their own interests, institutions and ideas about the policy. Understanding who are the actors involved from the various policy sectors concerned, what context they evolve in, but also how they own and frame the policy problem (ideas), and how this has changed over time, is crucial for those involved in HiAP implementation so that they can relate to and work together with actors from other policy sectors. © 2016 by Kerman University of Medical Sciences.

    Full Text Available While self-regulation has long been recognized as an important characteristic of an individual, instruments assessing the general aptitude of self-regulation remain limited especially in Asian countries. This study re-validated Carey et al.'s (2004 Short Self-Regulation Questionnaire based on a national sample of Taiwanese college students (N = 1,988. Item analysis, exploratory factor analysis, and confirmatory factor analysis (CFA yielded 22 items in five internally consistent factors. Descriptive findings showed that, a lack of proactiveness and volitional control, and a decrease of self-regulation throughout the college span appeared to be an overarching problem among Taiwanese college students. Furthermore, male students achieved lower self-regulation scores than female ones, and students in Services and STEM-related majors are in the need of self-regulation enhancement. Due to the generic measurement of individual's self-regulation traits, the Taiwanese Short Self-regulation Questionnaire (TSSRQ can be flexibly applied to various contexts and used to deal with different issues beyond learning such as college students' Internet or smartphone addiction. Through this study, we hope the validated TSSRQ can promote studies on self-regulation and associated antecedents and outcomes, in turn leveraging college students' life adjustment and well-being.

    Full Text Available Great Expectations is probably the most adapted and rewritten work of the Dickensian literary production. Since the author’s adaptation for his public readings, it was clear that the narration was not focused on the love story between Pip and Estella, but on the relationship between the orphan and the convict, his second father. In the last decades numerous transpositions have confirmed that Magwitch, despite his diegetic marginality, is the classic’s most magnetic character: The Boy and the Convict by Aylott (1909, Great Expectations: The Untold Story by Burstall (1987, Magwitch by Noonan (1982, Jack Maggs by Carey (1997, the recent spin-off by Supple, Magwitch (2012, and a self-published trilogy by Lester (2010-2011 feature Magwitch as a main character, to redeem him and to give him a better destiny than Dickens did. After an overview of the reasons for his reception, and a section on the transposing strategies used by rewritings and adaptations, this paper aims at showing the new attention to the theme of fatherhood or parenthood to which this character is strictly related. In particular, keeping in mind Sadrin’s analysis of Great Expectations in terms of the “family romance”, these works shed light on the metaphorical and metonymical meaning of Magwitch’s relationship with Britain and Australia.

    Full Text Available This research is based on the dryness of spiritual values in cosmography learning in college. This is because of the cosmographic material currently available contains only the cognitive domain. This condition makes cosmographic learning in college unable to make students as a person who glorifies God and pious in accordance with the mandate of Law Number 12 the year 2012. The research and development procedure is done by modifying the Dick and Carey model which is done through 7 stages. The results showed that the acceptance of teaching materials products reached 80, 42%. An important finding of this research is the integration of Quranic verses into teaching material can add the belief of the respondent to God Almighty for the creation of the universe. This makes the student become a person who glorifies God. Although spiritual intelligence is difficult to measure with various instruments,  at least the opinions of most respondents, it can be used as a benchmark that learning Al Quran-based cosmography can increase students' confidence in God Almighty.

    Citrate is an important stabilizing, reducing, and complexing reagent in the wet chemical synthesis of nanoparticles of silver and other metals, however, the exact nature of adsorbates, and its mechanism of action are still uncertain. Here, we applied X-ray photoelectron spectroscopy, soft X-ray absorption near-edge spectroscopy, and other techniques in order to determine the surface composition and to specify the citrate-related species at Ag nanoparticles immobilized from the dense hydrosol prepared using room-temperature reduction of aqueous Ag+ ions with ferrous ions and citrate as stabilizer (Carey Lea method). It was found that, contrary to the common view, the species adsorbed on the Ag nanoparticles are, in large part, products of citrate decomposition comprising an alcohol group and one or two carboxylate bound to the surface Ag, and minor unbound carboxylate group; these may also be mixtures of citrate with lower molecular weight anions. No ketone groups were specified, and very minor surface Ag(I) and Fe (mainly, ferric oxyhydroxides) species were detected. Moreover, the adsorbates were different at AgNPs having various size and shape. The relation between the capping and the particle growth, colloidal stability of the high-concentration sol and properties of AgNPs is briefly considered.

    Shelter dogs are typically cared for by staff and volunteers. At the Boston location of the Massachusetts Society for the Prevention of Cruelty to Animals, prior to 2009, any member of the public who was older than 16 years of age and attended 1 orientation could walk dogs available for adoption. There was no systematic method of training volunteers or staff to walk unruly, strong, or fearful dogs, nor was there any organized system of enrichment in the form of in-kennel or out-of-kennel training for the population of 20 to 40 dogs in the shelter. Using the Dick and Carey ( 1996 ) model of instructional design, a curriculum called "Safewalk" was devised and implemented. Safewalk created a hierarchical training system for volunteers. After training was implemented, outcomes and lengths of stay were then compared for dogs for the 3 years before and 4 years after Safewalk. Changes in adoption rates for pit bull-type dogs and non-pit bulls were significantly improved, and length of stay for non-pit bulls was significantly decreased. Other components of shelter life for dogs and people were also improved.

    Diplachne P. Beauv. comprises two species with C 4 (NAD-ME) photosynthesis. Diplachne fusca has a nearly pantropical-pantemperate distribution with four subspecies: D. fusca subsp. fusca is Paleotropical with native distributions in Africa, southern Asia and Australia; the widespread Australian endemic D. f. subsp. muelleri; and D. f. subsp. fascicularis and D. f. subsp. uninervia occurring in the New World. Diplachne gigantea is known from a few widely scattered, older collections in east-central and southern Africa, and although Data Deficient clearly is of conservation concern. A discussion of previous taxonomic treatments is provided, including molecular data supporting Diplachne in its newer, restricted sense. Many populations of Diplachne fusca are highly tolerant of saline substrates and most prefer seasonally moist to saturated soils, often in disturbed areas. Some populations of Diplachne fusca in southern Asia combine nitrogen-fixation, high salinity tolerance and palatibilty to livestock, which should be pursued with further research for purposes of soil reclamation. Diplachne fusca subsp. uninervia is the most invasive of the subspecies and is becoming weedy in some non-native areas, including in the Old World. This monograph provides detailed descriptions of all taxa, a key to the species and subspecies, geographic distributions and information on the anatomy of leaves, stems, lemmatal micromorphology and discussions of the chromosome numbers. Lectotypes are designated for: Atropis carinata Grisb.; Diplachne acuminata Nash; Diplachne capensis (Nees) Nees var. concinna Nees; Diplachne capensis (Nees) Nees var. obscura Nees, Diplachne capensis (Nees) Nees var. prolifera subvar. minor Nees, Diplachne halei Nash, Diplachne maritima E.P.

    Full Text Available A total of 301 adult hispine beetles of the genera Cephaloleia and Chelobasis were found in rolled leaves of plants of 17 species of Zingiberales (families Costaceae, Heliconiaceae, Maranthaceae, Musaceae, and Zingiberaceae during a field study at La Gamba, Golfito region, Costa Rica. Of these beetles, Cephaloleia belti was recorded from 12 potential host plant species, C. distincta from 7, C. dilaticollis from 5, C., Chelobasis bicolor, C. championi, and C. histrionica from 3, Chelobasis perplexa and C. instabilis from 2, whereas C. trivittata from only one. Of the plant species, Heliconia latispatha had 7 beetle species in its leaf rolls, Calathea lutea had 5, H. imbricata and H. rostrata had 4, H. stricta and Musa paradisiaca had 3, H. wagneriana had 2, while on H. vaginalis, H. danielsiana, H. densiflora, H. longiflora, Calathea crotalifera, C. platystachya, Goeppertia lasiophylla, Alpinia purpurata, Costus pulverulentus and Costus barbatus, H. densiflora, H. vaginalis, and H. danielsana only hispines of one species were found.Cephaloleia belti occurred together with beetles of six other hispine species, whereas Cephaloleia trivittata never shared a leaf roll with another hispine species. The remaining beetle species aggregated with one to four other hispines. Adults of C. belti and C. championi were frequently seen, occasionally also with C. dilaticollis, C. histrionica, and Chelobasis perplexa, to co-occur with the carabid Calophaena ligata in the same leaf roll without any sign of interspecific aggression.A comparison of host choices and the phylogeny of the hispines and of their host plants revealed no signs that beetles used species level phylogenetic relationships within the Zingiberales to food plants. Obviously, within this plant order, rolled-leaf hispines choose their plant hosts in a nearly opportunistic manner. Seemingly, they use differences among plants at higher taxonomic levels but within the Zingiberales, the availability of

    In corals a catalase-lipoxygenase fusion protein transforms arachidonic acid to the allene oxide 8R,9-epoxy-5,9,11,14-eicosatetraenoic acid from which arise cyclopentenones such as the prostanoid-related clavulones. Recently we cloned two catalase-lipoxygenase fusion protein genes (a and b) from the coral Capnella imbricata, form a being an allene oxide synthase and form b giving uncharacterized polar products (Lõhelaid, H., Teder, T., Tõldsepp, K., Ekins, M., and Samel, N. (2014) PloS ONE 9, e89215). Here, using HPLC-UV, LC-MS, and NMR methods, we identify a novel activity of fusion protein b, establishing its role in cleaving the lipoxygenase product 8R-hydroperoxy-eicosatetraenoic acid into the short-chain aldehydes (5Z)-8-oxo-octenoic acid and (3Z,6Z)-dodecadienal; these primary products readily isomerize in an aqueous medium to the corresponding 6E- and 2E,6Z derivatives. This type of enzymatic cleavage, splitting the carbon chain within the conjugated diene of the hydroperoxide substrate, is known only in plant cytochrome P450 hydroperoxide lyases. In mechanistic studies using 18O-labeled substrate and incubations in H218O, we established synthesis of the C8-oxo acid and C12 aldehyde with the retention of the hydroperoxy oxygens, consistent with synthesis of a short-lived hemiacetal intermediate that breaks down spontaneously into the two aldehydes. Taken together with our initial studies indicating differing gene regulation of the allene oxide synthase and the newly identified catalase-related hydroperoxide lyase and given the role of aldehydes in plant defense, this work uncovers a potential pathway in coral stress signaling and a novel enzymatic activity in the animal kingdom.

    Full Text Available The article covers some information on anthropogenic influence upon natural ecosystems that is considered to be one of the strongest factors for reducing biodiversity of Georgian flora. With this purpose, some species of fam. Iridaceae that need to be protected under in situ conditions are being studied. The paper focuses on the fam. Iridaceae. This family is particularly interesting as it unites a considerable number of valuable, beautifully flowering plants with ornamental leaves, representing different biomorphs. Particularly rare and endangered species are: Iris iberica, I. Grossheimii, I. Lycotis, I. Camillae, I. Elegantissima, etc. We have carried out complex studies of bio-ecological peculiarities of bulbous geophytes and ephemeroids of genus Iridodictyum winogradowii, Ir. Reticulatum, Siphonastilis lasica and Iuno caucasica. There has been studied rhythm of growth and development of vital cycle of monocarpic shootings and ways of their propagation in the sub arid zone of East Georgia. There should be mentioned that they have perfectly adapted to the conditions. Such rare species of rootstock plants like Iris iberica, I. Carthalinical. Aphylla, I. graminea, I. imbricata, I. timofejewii, I. prilipkoana, I. musulmanica, Siphonastilis lazica and others even give abundant self-seedlings that undoubtedly makes it possible to protect them from being finally extinct. All the investigated plants can be recommended for using in landscape architecture under the conditions of East Georgia that will contribute to conservation of the valuable genofond of relict and endemic plants of Georgian flora. The work deals with the results of in situ conservation of some of rare and endemic species of fam. Iridaceae from Iridaceae Juss family. According to IUCN categories, the studied taxaare discussed as the endangered species in nature.

  1. Oroclines - a century of discourse about curved mountain belts (Petrus Peregrinus Medal Lecture)

    Science.gov (United States)

    Van der Voo, Rob

    2014-05-01

    Exactly a century ago, in early 2014, a discussion appeared in the Journal of Geology by William H. Hobbs entitled "Mechanics of formation of arcuate mountains". In it, he notes how the concept of nappes "has now overcome all opposition in Switzerland" and, presumably in other countries just as much. With horizontal transport so central to the nappe concept, this must have paved the way for the idea that emplacement of trust sheets may have involved rotations. Where such rotations form a coherent regional pattern, a curved mountain belt may be the result. While the paper by Hobbs does not mention the word orocline, and while the dynamics of the situation is not yet illuminated, one must give credit to him for his foresights. The term "orocline" was introduced by S. Warren Carey of Tasmania in 1955, as part of a kinematic analysis of rhomb- and triangle-shaped basins and curved mountain belts. When the displacements involved in the analysis are undone, as he did, for instance, in the western Mediterranean, a grand scheme of simple convergent and divergent patterns emerges. Noteworthy is, of course, the fact that this mobilistic analysis preceded plate tectonics by more than a decade. From Carey (although not exactly in his words) we have inherited the definition of orocline, as "a thrust belt or orogen that is curved in map-view due to it having been bent or buckled about a vertical axis of rotation". Because oroclinal bending involves rotations, the declinations of paleomagnetic studies can be utilized to support and quantify them, and early efforts were already made in the 1960's and early 1970's to do so (e.g., Krs in the Carpathians; Ries & Shackleton in Cantabria; Roy, Opdyke & Irving in the Central Appalachians; Packer & Stone in Alaska). Curved mountain belts everywhere were subsequently investigated, and typically shown by paleomagnetists to be of the oroclinal variety. Few curved belts turned out to be curved from the start. Because these studies were

    Students are typically introduced to the relative motions of plates and its effects either through text-based descriptions, paper models, or both. However, though students may learn to repeat the description of the effects, many students still do not show a deeper understanding of the process, as shown by examinations of students before and after an introductory geology course (DeLaughter et al, 1998). This is because students are rarely affected by the information on a visceral level; because their preconceptions are never challenged, they never internalize the information as part of their model of how the world works. However, when concepts such as plate motions and their effects are presented to students as part of a tangible, physical experiment, the ideas can have a much greater impact (Carey et al, 1989). The students use the new information to build more complete mental models while learning that such models can and must change in response to new information (Herbert, 2003). When such experiments are performed in a geology class, they afford the students a direct and visceral experience that may enhance the learning process. In this exercise for middle school students, the effects of relative plate motions on overlying sediments are modeled through a simple and inexpensive set of experiments using sand and newspaper. These experiments provide qualitatively the same results as those performed by geologists researching various aspects of faulting and folding (e.g., Horsfield, 1977, Domingez et al., 2000). A secondary benefit of these experiments is that when the students do not pull the papers perfectly the combination of effects can mimic real terrains (e.g., transpressional) very closely. This intrusion of methodological errors can also lead to a lively discussion of how science is done and what the results of an experiment imply, thereby providing a pedagogical benefit as well. Thus students can be shown the effects of relative plate motions in a direct and

  5. The Nebular Hypothesis - A False Paradigm Misleading Scientists

    Myers, L. S.

    2005-05-01

    Science has reached a turning point in history after being misled for 250 years by Immanuel Kant's nebular hypothesis, the most fundamental assumption in science. The nebular hypothesis assumes all nine planets were created 4.5 billion years ago (Ga) as molten bodies that cooled with the same size and chemical composition they have today. Reevaluation of the nebular hypothesis proves it has been wrong since its inception. The proof has lain in plain sight for centuries-coal beds that could not have existed at the assumed time of creation because they formed on Earth's surface after creation of the planet when forests and swamps were exposed to solar energy. The coal beds were subsequently buried under overburden accreted in later millennia, steadily increasing Earth's mass and diameter. The coal beds and layers of overburden are proof Earth was not created 4.5 Ga but is growing and expanding by accretion of extraterrestrial mass and core expansion-a process termed "Accreation" (creation by accretion). Each process accelerates over time, but internal expansion exceeds the rate of external accretion. Because the nebular hypothesis is erroneous researchers assumed Earth's diameter never changes, and, faced with the possibility the Earth might be expanding after the Atlantic basin was discovered to be widening, this assumption led to the unworkable concept of subduction to maintain a constant diameter Earth. Subduction will prove to be one of the greatest errors in the history of science. Nullification of the nebular hypothesis also nullifies subduction and rejuvenates Carey's earth expansion theory. Accreation provides Carey's missing energy source and mechanism of expansion. Expansion is proved by morphologic evidence today's continents were once a single planetary landmass on a smaller Earth when today's oceans, covering 70% of the planet, did not exist 200-250 Ma. Despite hundreds of tons of meteorites and dust known to accrete daily, its cumulative effect has been

    Full Text Available Students enter the library science graduate program with a wide range of information and technology skills. Today’s graduate courses require students to be able to build web-based pathfinders, use social media, and search databases. This article examines the design and development of an introductory course for incoming library science graduate students that personalizes instruction and ensures that each student is ready for the rigors of graduate school. Taken during the first semester of the program, this introductory course teaches information and technology skills and concepts that are core to library science. The author explores the process of creating a computer-based course that addresses the diverse needs of this student population. Using a systematic approach to instructional design and development, the author outlines the steps in designing, developing, implementing, and evaluating an online, self-paced graduate course. Based on the Dick and Carey model, the process included identifying the instructional goals, conducting an instructional analysis, analyzing learners and contexts, writing performance objectives, developing assessment instruments, developing instructional strategies, developing and selecting instructional materials, designing and conducting formative evaluation of instruction, revising instruction, and designing and conducting summative evaluation. This process produced effective, efficient, and appealing instructional materials.

  8. On World Religion Adherence Distribution Evolution

    Science.gov (United States)

    Ausloos, Marcel; Petroni, Filippo

    Religious adherence can be considered as a degree of freedom, in a statistical physics sense, for a human agent belonging to a population. The distribution, performance and life time of religions can thus be studied having in mind heterogeneous interacting agent modeling. We present a comprehensive analysis of 58 so-called religions (to be better defined in the main text) as measured through their number of adherents evolutions, between 1900 and 2000, - data taken from the World Christian Trends (Barrett and Johnson, "World Christian Trends AD 30 - AD 2200: Interpreting the Annual Christian Megacensus", William Carey Library, 2001): 40 are considered to be "presently growing" cases, including 11 turn overs in the twentieth century; 18 are "presently decaying", among which 12 are found to have had a recent maximum, in the nineteenth or the twentieth century. The Avrami-Kolmogorov differential equation which usually describes solid state transformations, like crystal growth, is used in each case in order to obtain the preferential attachment parameter introduced previously (Europhys Lett 77:38002, 2007). It is not often found close to unity, though often corresponding to a smooth evolution. However large values suggest the occurrence of extreme cases which we conjecture are controlled by so-called external fields. A few cases indicate the likeliness of a detachment process. We discuss a few growing and decaying religions, and illustrate various fits. Some cases seem to indicate the lack of reliability of the data, but others some marked departure from Avrami law. Whence the Avrami evolution equation might be surely improved, in particular, and somewhat obviously, for the decaying religion cases. We point out two major difficulties in such an analysis: (1) the "precise" original time of apparition of a religion, (2) the time at which there is a maximum number of adherents, both information being necessary for integrating reliably any evolution equation.

  9. Magmatic storage conditions, decompression rate, and incipient caldera collapse of the 1902 eruption of Santa Maria Volcano, Guatemala

    Phase equilibria experiments and analysis of natural pumice and phenocryst compositions indicate the 1902 Santa Maria dacite was stored at ~ 140-170 MPa and 840-850 °C prior to eruption. H2O-saturated, cold-seal experiments conducted in vessels with an intrinsic log fO2 of NNO + 1 ± 0.5 show that the natural phase assemblage (melt + plagioclase + amphibole + orthopyroxene + Fe-Ti oxides + apatite) is stable from approximately 115-140 MPa at temperatures below ~ 825 °C, to ~ 840-860 °C at 150 MPa, to > 850 and Ridolfi et al., 2010) applied to experimental samples suggest two populations of amphiboles, phenocrysts grown during the experiments and inherited xenocrysts, but the pressure-temperature conditions returned by the geothermobarometer are routinely > 50 MPa and > 50 °C greater than experimental run conditions; precise estimates of magmatic conditions based solely upon amphibole composition are likely inaccurate. The experimental results and analysis of natural crystals suggest that although the natural amphiboles likely record a broad range of magmatic conditions, only the lower bounds of that range reflect pre-eruptive storage conditions. Comparison of Santa Maria microlite abundances with decompression experiments examining other silicic systems from the literature suggests that the 1902 dacite decompressed at the rate of ~ 0.005 to 0.01 MPa/s during the eruption. Applying the decompression rate with the previously described eruption rate of approximately 2-3 × 108 kg/s (Williams and Self, 1983; Carey and Sparks, 1986) to the conduit model CONFLOW reveals that the eruption conduit was dike-like with an along-strike length > 1 km. Despite depositing ~ 20 km3 of dacite tephra (equivalent to ~ 8.5 km3 magma), the 1902 eruption did not form an obvious caldera. This work suggests that collapse of the dike-like conduit terminated the eruption, preventing full caldera collapse.

  10. Petrofabric changes in heated and irradiated salt from Project Salt Vault, Lyons, Kansas

    International Nuclear Information System (INIS)

    Holdoway, K.A.

    1972-01-01

    Rock salt was heated and irradiated in situ by implanted radioactive wastes during the Project Salt Vault experiment which was carried out at Lyons, Kansas, in the abandoned Carey Salt mine between 1965 and 1967. It was found that irradiation results in coloration of the salt, producing colors ranging from blue-black nearest the radiation source, to pale blue and purple farther from the source. Bleached areas are common in the radiation-colored salt, many representing trails produced by the migration of fluid inclusions towards the heat source. These visible trails are thought to have formed during the cooling down of the salt after the removal of the heaters and radiation sources. The distribution of primary structures in the salt suggests that little migration, if any, occurred during the course of the experiment. It is proposed that radiolysis of the brine within the inclusions may have led to the production of gases which impeded or prevented migration. Evidence of strain was observed in slip planes at 4 in. (10 cm) and between 5.5 and 10 in. (13.5 to 25.4 cm) from the array hole. Deformed bleached areas in the salt between the areas were slip planes are developed suggest that slight plastic deformation or flow may have occurred at 6 in. (15 cm) from the array hole. Differential thermal analysis shows that the maximum amount of stored energy also occurs at 6 in. (15 cm) from the array hole. This region may therefore represent the zone where the combined effect of stress and radiation was greatest

    Groundwater suitability for water supply and agriculture in an island coastal area may easily be influenced by seawater intrusion. The aim of this study was to investigate seawater intrusion to the suitability of the groundwater for water supply and oil palm cultivation on Carey Island in Malaysia. This is the first study that used integrated method of geo-electrical resistivity and hydrogeochemical methods to investigate seawater intrusion to the suitability of groundwater for water supply and oil palm cultivation at two different surface elevation and land cover. The relationship between earth resistivity, total dissolved solids and earth conductivity was derived with water type classifications and crop suitability classification according to salinity, used to identify water types and also oil palm tolerance to salinity. Results from the contour resistivity and conductivity maps showed that the area facing severe coastal erosion (east area) exhibited unsuitable groundwater condition for water supply and oil palm at the unconfined aquifer thickness of 7.8 m and 14.1 m, respectively. Comparing to the area that are still intact with mangrove (west area), at the same depth, groundwater condition exhibits suitable usage for both socioeconomic activities. Different characteristics of surface elevation and land cover are paramount factors influencing saltwater distribution at the west and east area. By the end of the twenty-first century there will no longer be suitable water for supply and oil palm plantation based on the local sea-level rise prediction and Ghyben–Herzberg assumption (sharp interface), focusing on the severe erosion area of the study site.

Results: Around 34 patients with inflammatory arthritis were switched from reference product to biosimilar infliximab in 2014: 50% female, mean age 55 years (standard deviation=12.9, mean disease duration 14.79 years (9.7, median duration on infliximab 57 months, and two-thirds on oral disease-modifying antirheumatic drugs. There was no difference in efficacy or safety in the first 6 months of therapy. By the end of 2015, the mean follow-up on biosimilar infliximab was 15.8 (standard deviation=6.3 months. Our results showed no significant difference in Health Assessment Questionnaire score, patient global assessment of disease activity, number of disease flares, or the medication dose between the originator and the biosimilar infliximab. However, reported pain and C-reactive protein values were significantly higher during the longer follow-up period (p=0.043, 0.001 respectively. There was no significant difference in the number of adverse events or infusion reactions during follow-up periods. Only five (14.7% patients discontinued the biosimilar infliximab. Conclusion: Our patients experienced similar efficacy and safety for managing their arthritis with the biosimilar infliximab as the reference product infliximab, but at a much lower cost.

    Full Text Available Background: Extraction in orthodontics are carried out in the cases where there is space deficiency to align the teeth. The elective extraction of first or second premolars has been discussed in the literature for more than 50 years. In the 1940s and 1950s Nance, Dewel and Carey reviewed this as a useful option, and in the 1970s Logan and other leading orthodontists favoured the extraction as choice. It is not always the elective extraction of premolar is a smooth drive for the surgeon as well as to patient. Sometimes the elective extraction of premolar result in complications, which might be due to both anatomical and surgical factors. Methodology: The study sample consisted of 100 patients referred for one or more orthodontic extractions to the department of oral and maxillofacial surgery were included in this retrospective study at the vivekanandha dental college for women tiruchengode between November 2014 and May 2016. All referrals were from the department of orthodontics. A survey was carried out to record the intraoperative risks and correlated with its morbidity as when occured. All intraoperative morbities were managed appropriately as required. Result and Conclusion: Between November 2014 and May 2016, 100 patients had one or more premolar teeth removed by the oral surgeons. The sample size was 100 patients who had a total of 334 premolars removed. The sample's mean age was 11.4+\\- 8.4 years, and 57.0% were male. The average number of teeth extracted per patient was 2.34 +\\- 1.46, and 73.8% had complete root development. More than 93.4% of subjects had normal root and bone morphology, whereas 35.65% had variations in root forms and bone texture. The intra-operative and post operative complication rates were 7.4% and 1.9%, respectively. Complications were generally minor (91.9% and were managed nonoperatively on an outpatient basis. There were no case of oral antral communication.

  16. The geocentric particulate distribution: Cometary, asteroidal, or space debris?

    Definition of the Low Earth Orbit (LEO) particulate environment has been refined considerably with the analysis of data from NASA's Long Duration Exposure Facility (LDEF). Measurements of the impact rates from particulates ranging from sub-micron to millimetres in dimension and, especially, information on their directionality has permitted new scrunity of the sources of the particulates. Modelling of the dynamics of both bound (Earth orbital) and unbound (hyperbolic interplanetary) particulates intercepting LDEF's faces leads to the conclusion that the source is dominantly interplanetary for particle dimensions of greater than some 5 microns diameter; however the anisotropy below this dimension demands lower velocities and is compatible with an orbital component. Characteristics of the LDEF interplanetary component are compatible with familiar meteoroid sources and deep space measurements. Understanding of the orbital component which exceeds the interplanetary flux by a factor of 4 is less clear; although the very small particulates in orbit have been associated with space debris (Lawrance and Brownlee, 1986) this data conflicts with other measurements (McDonnell, Carey and Dixon, 1984) at the same epoch. By analysis of trajectories approaching the Earth and its atmosphere, we have shown that a significant contribution could be captured by aerocapture, i.e., atmospheric drag, from either asteroidal or cometary sources; such enhancement is unlikely however to provide the temporal and spatial fluctuations observed by the LDEF Interplanetary Dust Experiment (Mullholland et al. 1992). A further new mechanism is also examined, that of aerofragmentation capture, where an atmospheric grazing trajectory, which would not normally lead to capture, leads to fragmentation by thermal or mechanical shock; the microparticulates thus created can be injected in large numbers, but only into short-lifetime orbits. The concentration in one particular orbit plane, could explain the

    In contrast to the considerable volume of international research on infant attachment development, significantly less research has been conducted in China. The present study was designed to identify the patterns of mother-infant attachment in Shanghai and to explore the influence factors. The subjects included 160 healthy infant-mother dyads. Infant attachment and temperament were assessed with the Strange Situation Procedure and Carey's temperament questionnaire, respectively; the mother's personality, maternal sensitivity and marital satisfaction were assessed with Eysenck's personality questionnaire, Maternal Behavior Q-sort Manual Version 3.1 and Olson's marital questionnaire, respectively. A self-formulated questionnaire of family environment factors was completed by the infant's mother. Of the 160 infants, 68.2% were rated as securely attached (B) and 31.8% as insecurely attached. Of those infants rated as insecurely attached, 7.5% were characterized as avoidant (A), 21.8% as resistant (C) and 2.5% as disorganized (D). Maternal sensitivity and marital satisfaction as well as the approachability dimension of infant temperament, were significantly different between securely attached infants and insecurely attached infants. From a temperament perspective, resistant infants showed higher-level intensity of reaction than avoidant infants. Moreover, multiple caregivers in the family and infant's sleeping with other caregivers at night were more likely to be associated with insecure mother-infant attachment. There exist certain cultural characteristics in mother-infant attachment patterns in Shanghai. The influence factors are related with the high involvement of non-mother caregivers as well as maternal sensitivity, marital satisfaction and infant's temperament characteristics.

However the influence of dietary supplemented n-3-LC-PUFAs on inflammation-related cell death and proliferation after middle cerebral artery occlusion (MCAo-induced stroke is unknown. We have previously demonstrated that anxiety-like and hyperactive locomotor behaviors are reduced in n-3-LC-PUFA-fed MCAo animals. Thus in the present study, male hooded Wistar rats were exposed to MCAo or sham surgeries and examined behaviorally 6 weeks later, prior to euthanasia and examination of lesion size, cell death and proliferation in the dentate gyrus, cornu ammonis region of the hippocampus of the ipsilesional hemispheres, and the thalamus of the ipsilesional and contralesional hemispheres. Markers of cell genesis and cell degeneration in the hippocampus or thalamus of the ipsilesional hemisphere did not differ between surgery and diet groups 6 weeks post MCAo. Dietary supplementation with n-3-LC-PUFA decreased cell degeneration and increased cell proliferation in the thalamic region of the contralesional hemisphere. MCAo–associated cell degeneration in the hippocampus and thalamus positively correlated with anxiety-like and hyperactive locomotor behaviors previously reported in these animals. These results suggest that anti-inflammatory n-3-LC-PUFA supplementation appears to have cellular protective effects after MCAo in the rat, which may affect behavioral outcomes.

    As the US oceanographic research fleet shrinks, reducing seagoing opportunities for scientists and students, remote participation in cruises via telepresence will become increasingly vital. The Nautilus Exploration Program is improving the experience of shoreside participants through the development of new tools and methodologies for connecting them to expeditions in real time increasing accessibility to oceanographic cruises. The Scientist Ashore Program is a network of scientists around the world who participate in Exploration Vessel Nautilus expeditions from their own labs or homes. We have developed a suite of collaboration tools to allow scientists to view video and data in real time, as well as to communicate with ship-based and other shore-based participants to enable remote participation in cruises. Post-cruise, scientists and students may access digital data and biological and geological samples from our partner shore-based repositories: the University of Rhode Island Inner Space Center, Harvard Museum of Comparative Zoology, and URI Marine Geological Samples Lab. We present examples of successful shore-based participation by scientists and students in Nautilus expeditions. In 2013, Drs. Cheadle and John stood watch 24/7 with ten undergraduate and graduate students at the University of Wyoming, recording geologic features and samples, during a cruise to the Cayman Rise. The Straits of Florida & Great Bahama Bank cruise was co-led by Dr. Eberli at the University of Miami in 2014, greatly complementing existing data. That same year, the ISC hosted four early career scientists and their twelve undergraduate students who led dives from shore in collaboration with Dr. Carey, Lead Scientist at sea on the Kick'em Jenny Volcano & the Barbados Mud Volcanoes cruise. In 2015, 12 Scientists Ashore worked in collaboration with the ship-based team on the exploration of Galapagos National Park, and more than 20 are working with OET on post-cruise data & sample analysis.

    Aims: We designed this study to get insight into the disorder of lipid metabolism during cholesterol gallstone formation and evaluate the effect of ursodeoxycholic acid on the improvement of bile lithogenicity and on expression of lipid related genes. Methods: Rabbit cholesterol gallstone models were induced by high cholesterol diet. Bile, blood and liver tissues were obtained from rabbits after 0, 1, 2, 3, 4 and 5 weeks. Bile and blood lipids were measured enzymatically. 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR), cytochrome P450, family 7, subfamily A, polypeptide 1 (CYP7A1) and sterol carrier protein 2 (SCP2) mRNA expressions were detected by using quantitative real-time RT-PCR. Cholesterol saturation index (CSI) was calculated by using Carey table to represent the bile lithogenicity. Results: Rates of gallstone formation of the 4 and 5 week treatment groups were 100 %, but that of the ursodeoxycholic acid treatment group was only 33.3 %. Expression of HMGCR and SCP2 mRNA in the 4 week group was upregulated and that of CYP7A1 mRNA decreased as compared with the 0 week group. Ursodeoxycholic acid could significantly extend nucleation time of bile and lower CSI. Ursodeoxycholic acid could reduce the expression of SCP2, but couldn't influence expression of HMGCR and CYP7A1. Conclusions: Abnormal expression of HMGCR, CYP7A1 and SCP2 might lead to high lithogenicity of bile. Ursodeoxycholic acid could improve bile lipids and lower bile lithogenicity, thereby reducing the incidence of gallstones. So it might be a good preventive drug for cholesterol gallstones.

  4. What makes a movement a gesture?

    Theories of how adults interpret the actions of others have focused on the goals and intentions of actors engaged in object-directed actions. Recent research has challenged this assumption, and shown that movements are often interpreted as being for their own sake (Schachner & Carey, 2013). Here we postulate a third interpretation of movement-movement that represents action, but does not literally act on objects in the world. These movements are gestures. In this paper, we describe a framework for predicting when movements are likely to be seen as representations. In Study 1, adults described one of three scenes: (1) an actor moving objects, (2) an actor moving her hands in the presence of objects (but not touching them) or (3) an actor moving her hands in the absence of objects. Participants systematically described the movements as depicting an object-directed action when the actor moved objects, and favored describing the movements as depicting movement for its own sake when the actor produced the same movements in the absence of objects. However, participants favored describing the movements as representations when the actor produced the movements near, but not on, the objects. Study 2 explored two additional features-the form of an actor's hands and the presence of speech-like sounds-to test the effect of context on observers' classification of movement as representational. When movements are seen as representations, they have the power to influence communication, learning, and cognition in ways that movement for its own sake does not. By incorporating representational gesture into our framework for movement analysis, we take an important step towards developing a more cohesive understanding of action-interpretation.

    The decisional balance worksheet (DBW), an open-ended measure of motivation to change, may be used to record the perceived advantages and disadvantages of substance use as well as alternative behaviors. Recent findings have indicated that the open-ended DBW can be quantified to validly reflect college students' level of motivation to reduce their drinking (Collins, Carey, & Otto, 2009). The goal of the current study was to enhance our understanding of college students' perceived advantages and disadvantages of drinking by qualitatively examining the content of their decisional balance. Participants were undergraduate college students at a 4-year university (N = 760) who participated in a randomized controlled trial of online brief motivational interventions. Using the DBW, participants recorded the advantages and disadvantages of their current drinking. Conventional content analysis methods were used to extract common themes. Social, enjoyment, and psychological reasons were the most commonly mentioned advantages of drinking, whereas physical side effects, expense and interference with goals were the most commonly mentioned disadvantages of drinking. These findings show that college students primarily use alcohol for enjoyment, particularly in social situations, as well as for coping with stress and social anxiety. On the other hand, many college students report having physical side effects from drinking as well as other kinds of concerns (e.g., expense, calories). Findings suggest that using the open-ended DBW may result in a more client-centered and accurate representation of what college students perceive as advantages and disadvantages to drinking than established, Likert-scale measures of decisional balance.

  6. Struggles with learning about scientific models in a middle school science classroom

    Loper, Suzanna Jane

    Two important goals in science education are teaching students about the nature of science and teaching students to do scientific inquiry. Learning about scientific models is central to both of these endeavors, but studies have shown that students have very flawed and limited understandings of the nature and purposes of scientific models (Carey & Smith, 1993; Grosslight, Unger, & Jay, 1991; Lederman, 1992). In this dissertation I investigate the processes of teaching and learning about scientific models in an 8th grade classroom in an urban middle school. In order to do so, I examine recordings of student and teacher talk about models across a period of two months in which students completed two independent inquiry projects, using the Inquiry Island software and curriculum (Eslinger, 2004; Shimoda, White, & Frederiksen, 2002; White, Shimoda, & Frederiksen, 2000). My analysis draws on video records of small-group work and whole-class interactions, as well as on students' written work. I find that in this classroom, students struggled to understand the nature and purpose of scientific models. I analyze episodes in the classroom talk in which models appeared to be a source of trouble or confusion, and describe the ways in which the teacher attempted to respond to these troubles. I find that in many cases students appeared to be able to produce scientific models of the proper form, yet still struggled with displaying an understanding of what a model was, or of the functions of models in scientific research. I propose directions for further research and curriculum development in order to build on these findings. In particular, I argue, we need to design ways to help students engage in scientific modeling as a social and communicative practice, and to find ways to build from their everyday reasoning and argumentation practices. My research also reinforces the importance of looking at classroom talk, not just pre- and post-assessments, in order to understand teaching and

    The framework for teaching and learning in the 21st century was prepared with 4Cs criteria. Learning providing opportunity for the development of students' optimal creative skills is by implementing collaborative learning. Learners are challenged to be able to compete, work independently to bring either individual or group excellence and master the learning material. Virtual laboratory is used for the media of Instrumental Analytical Chemistry (Vis, UV-Vis-AAS etc) lectures through simulations computer application and used as a substitution for the laboratory if the equipment and instruments are not available. This research aims to design and develop collaborative-creative learning model using virtual laboratory media for Instrumental Analytical Chemistry lectures, to know the effectiveness of this design model adapting the Dick & Carey's model and Hannafin & Peck's model. The development steps of this model are: needs analyze, design collaborative-creative learning, virtual laboratory media using macromedia flash, formative evaluation and test of learning model effectiveness. While, the development stages of collaborative-creative learning model are: apperception, exploration, collaboration, creation, evaluation, feedback. Development of collaborative-creative learning model using virtual laboratory media can be used to improve the quality learning in the classroom, overcome the limitation of lab instruments for the real instrumental analysis. Formative test results show that the Collaborative-Creative Learning Model developed meets the requirements. The effectiveness test of students' pretest and posttest proves significant at 95% confidence level, t-test higher than t-table. It can be concluded that this learning model is effective to use for Instrumental Analytical Chemistry lectures.

    Marijuana motives are a proximal variable to marijuana use. This research aimed to adapt and validate the short form of the Marijuana Motives Measure (MMM; Simons, Correia, Carey, y Borsari, 1998), the MMM SF, in Spanish.  The sample comprised 232 participants (mean age = 25.11 (7.58), 50.43% males) who had tried marijuana at least once in their lifetime. Item and Rasch analyses were performed to choose the final pool of 15 items. Confirmatory Factor Analysis (CFA) showed an adequate 5-factor structure (S-BX2(80) = 121.30, p = .002; NNFI = .944; CFI = .958; IFI = .959; MFI = .915; RMSEA = .047(0.029, 0.063); AIC = -38.70), and the multi-group CFA between males and females showed acceptable fit indices (S-BX2(160) = 230.01, p = .000; NNFI = .900; CFI = .924; IFI = .927; MFI = .860; RMSEA = .062(.043, .078); AIC = -89.99). The questionnaire indicated metric (S-BX2diff (15) = 13.61, p = .556)), scalar (S-BX2diff (15) = 23.15, p = .081)) and error measurement invariance (S-BX2diff (15) = 8.65, p = .895)) between gender groups. The internal consistencies and ordinal omega of the scales were between .79 and .90. In the regression analysis, enhancement, coping and low conformity motives predicted frequency and quantity of marijuana smoked. The best predictor of frequency and quantity consumed during the heaviest smoking period was enhancement, while coping and, to a lesser extent, low conformity, were the only predictors of cannabis-related problems when marijuana frequency and quantity were controlled for.  The MMM SF shows adequate psychometric properties and is a suitable instrument to assess marijuana motives, especially during time-limited sessions.

  9. GEODYNAMIC WAVES AND GRAVITY

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available  Gravity phenomena related to the Earth movements in the Solar System and through the Galaxy are reviewed. Such movements are manifested by geological processes on the Earth and correlate with geophysical fields of the Earth. It is concluded that geodynamic processes and the gravity phenomena (including those of cosmic nature are related.  The state of the geomedium composed of blocks is determined by stresses with force moment and by slow rotational waves that are considered as a new type of movements [Vikulin, 2008, 2010]. It is shown that the geomedium has typical rheid properties [Carey, 1954], specifically an ability to flow while being in the solid state [Leonov, 2008]. Within the framework of the rotational model with a symmetric stress tensor, which is developed by the authors [Vikulin, Ivanchin, 1998; Vikulin et al., 2012a, 2013], such movement of the geomedium may explain the energy-saturated state of the geomedium and a possibility of its movements in the form of vortex geological structures [Lee, 1928]. The article discusses the gravity wave detection method based on the concept of interactions between gravity waves and crustal blocks [Braginsky et al., 1985]. It is concluded that gravity waves can be recorded by the proposed technique that detects slow rotational waves. It is shown that geo-gravitational movements can be described by both the concept of potential with account of gravitational energy of bodies [Kondratyev, 2003] and the nonlinear physical acoustics [Gurbatov et al., 2008]. Based on the combined description of geophysical and gravitational wave movements, the authors suggest a hypothesis about the nature of spin, i.e. own moment as a demonstration of the space-time ‘vortex’ properties.

    The chytrid fungus Batrachochytrium dendrobatidis is a known pathogen of anuran amphibians, and has been correlated with amphibian die-offs worldwide (Daszak et. al. 1999. Emerging Infectious Diseases 5:735-748). In Colorado, B. dendrobatidis has infected Boreal toads (Bufo boreas) (Muths et. al., in review) and has been identified on museum specimens of northern leopard frogs (Rana pipiens) (Carey et. al. 1999. Develop. Comp. Immunol. 23:459-472). We report the first verified case of chytrid fungus in chorus frogs (Pseudacris triseriata) and wood frogs (Rana sylvatica) in the United States. We collected seven P. triseriata, and two adult and two juvenile R. sylvatica in the Kawuneeche Valley in Rocky Mountain National Park (RMNP) during June 2001. These animals were submitted to the National Wildlife Health Center (NWHC) as part of an amphibian health evaluation in RMNP. Chorus frogs were shipped in one container. Wood frog adults and juveniles were shipped in two separate containers. Histological examinations of all chorus frogs and 3 of 4 wood frogs were positive for chytrid fungus infection. The fourth (adult) wood frog was too decomposed for meaningful histology. Histological findings consisted of multifocally mild to diffusely severe infections of the epidermis of the ventrum and hindlimb digital skin. Chytrid thalli were confined to the thickened epidermis (hyperkeratosis), were spherical to oval, and occasional thalli contained characteristic discharge pores or zoospores (Green and Kagarise Sherman 1999. J. Herpetol 35:92-103; Fellers et al. 2001. Copeia 2001:945-953). We cannot confirm that all specimens carried the fungus at collection, because infection may have spread from one individual to all other individuals in each container during transport. Further sampling of amphibians in Kawuneeche Valley is warranted to determine the rate of infection and mortality in these populations.

There is also increasing evidence that male partner involvement positively impacts non-HIV related outcomes, such as skilled attendance at delivery, exclusive breastfeeding, uptake of effective contraceptives, and infant immunizations. Despite these associations, male partner involvement remains low, especially when offered in the standard antenatal clinic setting. In this review we explore strategies for improving rates of antenatal male partner HIV testing and argue that the role of male partners in PMTCT must evolve from one of support for HIV-infected pregnant and breastfeeding women to one of comprehensive engagement in prevention of primary HIV acquisition, avoidance of unintended pregnancies, and improved HIV-related care and treatment for the HIV-infected and uninfected women, their partners, and children. Involving men in all components of PMTCT has potential to contribute substantially to achieving virtual elimination of mother-to-child HIV transmission; promoting partner-friendly programs and policies, as well as pursuing research into numerous gaps in knowledge identified in this review, will help drive this process.

    The HDV ribozyme self-cleaves by a chemical mechanism involving general acid-base catalysis to generate a 2′,3′-cyclic phosphate and a 5′-hydroxyl termini. Biochemical studies from several laboratories have implicated C75 as the general acid and hydrated magnesium as the general base. We have previously shown that C75 has a pKa shifted > 2 pH units toward neutrality [Gong, B., Chen, J. H., Chase, E., Chadalavada, D. M., Yajima, R., Golden, B. L., Bevilacqua, P. C., and Carey, P. R. (2007) J. Am. Chem. Soc. 129, 13335–13342.], while in crystal structures, it is well-positioned for proton transfer. However no crystallographic evidence for a hydrated magnesium poised to serve as a general base in the reaction has been observed in high-resolution crystal structures of various reaction states and mutants. Herein, we use solution kinetic experiments and parallel Raman crystallographic studies to examine the effects of pH on rate and Mg2+-binding properties of wild-type and 7-deazaguanosine mutants of the HDV ribozyme. These data suggest that a previously-unobserved hydrated magnesium ion interacts with the N7 of the cleavage site G•U wobble base pair. Integrating this metal ion binding site with the available crystal structures provides a new three-dimensional model for the active site of the ribozyme that accommodates all available biochemical data and appears competent for catalysis. The position of this metal is consistent with a role of a magnesium-bound hydroxide as a general base as dictated by biochemical data. PMID:19178151

    The value of clients' reports of their experiences in therapy is widely recognized, yet quantitative methodology has rarely been used to measure clients' self-reported perceptions of what is helpful over a single session. A video-rating method using was developed to gather data at brief intervals using process measures of client perceived experience and standardized measures of working alliance (Session Rating Scale; SRS). Data were collected over the course of a single video-recorded session of cognitive therapy (Method of Levels Therapy; Carey, 2006; Mansell et al., 2012). We examined the acceptability and feasibility of the methodology and tested the concurrent validity of the measure by utilizing theory-led constructs. Eighteen therapy sessions were video-recorded and clients each rated a 20-minute session of therapy at two-minute intervals using repeated measures. A multi-level analysis was used to test for correlations between perceived levels of helpfulness and client process variables. The design proved to be feasible. Concurrent validity was borne out through high correlations between constructs. A multi-level regression examined the independent contributions of client process variables to client perceived helpfulness. Client perceived control (b = 0.39, 95% CI .05 to 0.73), the ability to talk freely (b = 0.30, SE = 0.11, 95% CI .09 to 0.51) and therapist approach (b = 0.31, SE = 0.14, 95% CI .04 to 0.57) predicted client-rated helpfulness. We identify a feasible and acceptable method for studying continuous measures of helpfulness and their psychological correlates during a single therapy session.

    A successful radioprotector is the one, which essentially renders protection from the multi-organ dis-function syndrome (MODS) caused by the total body exposure to ionizing radiation. Our rationale is that and instead of a single molecule, a group of molecules/compounds working synergistically can combat the MODS more effectively. Plant extracts offer natural combinations of a plethora of compounds, which act through different mechanisms and are, therefore, the ideal choice. Plants of Himalayan regions have survived under extreme climatic conditions through millions of years and are expected to harbor a battery of anti-stress adaptive molecules offering survival benefits. Our group is actively engaged in developing composite herbal radioprotective preparations from Himalayan Plants. This group is working to develop radiation countermeasures by tapping the essential complex phytochemicals from the plants inhabiting extreme climatic zones of Himalayas. In our laboratory, systematic studies were undertaken to investigate some of these plants located at high altitude regions of Himalayas viz. Hippophae rhamnoides, Rhodiola imbricata and Podophylium hexandruin. The most effective preparation from each of these plants individually, could provide more than 80% survival benefit to the irradiated (10 Gy) mice population against zero per cent survival in non-drug treated irradiated (10 Gy) mice population. It was observed that whole extracts of plant provided much better protection than the partial extracts/fractions. It was also observed that some of the partial extracts/fractions although, provided much higher survival benefits, yet were found to be unsuitable for drug development due to much higher mutagenic and/or recombinogenic effects in comparison to the whole extracts, One of the preparations from leaves of Hippophae rhamnoides (drug) showed more than 90% survival benefits in the irradiated mice population. Only one time intra-peritoneal administration of the drug

    Full Text Available We estimated the nutritive value, vitamin content, amino acid composition, fatty acid content, and mineral profile of a phytococktail comprising sea buckthorn (Hippophae rhamnoides, apricot (Prunus armeniaca, and roseroot (Rhodiola imbricata from trans-Himalaya. The free vitamin forms in the phytococktail were determined by rapid resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS. Vitamin E and B-complex vitamins were detected as the principle vitamins. Reversed-phase high performance liquid chromatography (RP-HPLC with pre-column derivatization was used for identification and quantification of amino acids. Eight essential and eleven non-essential amino acids were quantified, and the content ranged between 76.33 and 9485.67 µg/g. Among the essential amino acids, L-methionine, L-phenylalanine, L-lysine, L-leucine, and L-histidine were found to be the dominant contributors. We also quantified the fatty acids in the phytococktail by using gas chromatography coupled with a flame ionization detector (GC-FID with fatty acid methyl esters (FAMEs derivatization. The analysis revealed the presence of 4 major fatty acids contributing to the total lipid content. Palmitic acid was found to be the rich source of saturated fatty acid (SFA and constituted ∼31% of the total lipid content. Among the unsaturated fatty acids (UFAs, palmitoleic acid (43.47%, oleic acid (20.89%, and linoleic acid (4.31% were prominent. The mineral profiling was carried out by inductively coupled plasma optical emission spectrometer (ICP-OES, and it was found to contain a number of important dietary mineral elements. The harsh climatic conditions, difficult terrain, and logistic constraints at high altitude regions of Indian trans-Himalayan cold desert lead to the scarcity of fresh fruits and vegetables. Therefore, the source of multiple vitamins, essential amino acids, fatty acids, and dietary minerals from the phytococktail would provide great health benefit

    Full Text Available Phytoplankton drives primary productivity in marine pelagic systems. This is also true for the oligotrophic waters in coral reefs, where natural and anthropogenic sources of nutrients can alter pelagic trophic webs. In this study, microphytoplankton assemblages were characterized for the first time in relation to expected coral spawning dates in the Caribbean. A hierarchical experimental design was used to examine these assemblages in Los Roques archipelago, Venezuela, at various temporal and spatial scales for spawning events in both 2007 and 2008. At four reefs, superficial water samples were taken daily for 9 days after the full moon of August, including days before, during and after the expected days of coral spawning. Microphytoplankton assemblages comprised 100 microalgae taxa at up to 50 cells per mL (mean ± 8 SD and showed temporal and spatial variations related to the coral spawning only in 2007. However, chlorophyll a concentrations increased during and after the spawning events in both years, and this was better matched with analyses of higher taxonomical groups (diatoms, cyanophytes and dinoflagellates, that also varied in relation to spawning times in 2007 and 2008, but asynchronously among reefs. Heterotrophic and mixotrophic dinoflagellates increased in abundance, correlating with a decrease of the diatom Cerataulina pelagica and an increase of the diatom Rhizosolenia imbricata. These variations occurred during and after the coral spawning event for some reefs in 2007. For the first time, a fresh-water cyanobacteria species of Anabaena was ephemerally found (only 3 days in the archipelago, at reefs closest to human settlements. Variability among reefs in relation to spawning times indicated that reef-specific processes such as water residence time, re-mineralization rates, and benthic-pelagic coupling can be relevant to the observed patterns. These results suggest an important role of microheterotrophic grazers in re

    Market is the main place for transactions of medicinal plants and traditional ingredients by local community in the Karo regency, North Sumatra, Indonesia. This is the first study to document the local knowledge of traders on and the diversity of the medicinal plants. The investigation was carried out in the Kabanjahe traditional market, in the Karo regency. The research goal was to reveal the local knowledge, diversity and utilization of medicinal plants, which have been traded in the Kabanjahe traditional market, as a basis for conservation efforts. The study was conducted through ethnobotanical approach using market surveys. All traders of medicinal plants were surveyed applying in-depth interviews and participative observations. Data were analyzed qualitatively using descriptive statistics. The diversity of medicinal plants was expressed in term of the Shannon-Wiener diversity index (H'), whereas the similarity among traders was indicated by Jaccard index (Ji). Traders of medicinal plants stored the simplicia of medicinal plants in chest of drawers, plastic baskets, plastic bags, and in the air by suspending them from the the stall ceilings. We recorded 344 species, 217 genera and 90 families of medicinal plants. Those that were sold mostly belong to Zingeberaceae (20 species), Poaceae (19 species), and Asclepiadaceae (17 species), and the species received high consumers demand, mostly belong to Zingiberaceae, Rutaceae, and Asclepidiaceae. Asclepidiaceae was used to treat diseases like cancer and heart problems. The Shannon-Wiener diversity index of medicinal plants at the Kabanjahe traditional market was high (H'= 5.637). The high Jaccard similarity index (Ji>0.56) suggested that the traders were trading similar species of medicinal plants. Kabanjahe traditional market is the center for the sale of of medicinal plants as traditional ingredients. Several species are well known for their pharmacological properties but others, [such as: Dischidia imbricata (Blume

    Among the many factors that potentially influence the rate at which nitrogen (N) becomes available to plants in terrestrial ecosystems are the identity and diversity of species composition, frequency of disturbance or stand turnover, and time. Replicated suites of investigator-designed communities afforded an opportunity to examine the effects of those factors on net N mineralization over a 12-year period. The communities consisted of large-stature perennial plants, comprising three tree species (Hyeronima alchorneoides, Cedrela odorata, and Cordia alliodora), a palm (Euterpe oleracea), and a large, perennial herb (Heliconia imbricata). Trees were grown in monoculture and in combination with the other two life-forms; tree monocultures were subjected to rotations of one or four years, or like the three-life-form systems, left uncut. The work was conducted on fertile soil in the humid lowlands of Costa Rica, a site with few abiotic constraints to plant growth. Rates of net N mineralization and nitrification were high, typically in the range of 0.2-0.8 microg x g(1) x d(-1), with net nitrification slightly higher than net mineralization, indicating preferential uptake of ammonium (NH4+) by plants and microbes. Net rates of N mineralization were about 30% lower in stands of one of the three tree species, Hyeronima, than in stands of the other two. Contrary to expectations, short-rotation management (one or four years) resulted in higher net rates of N mineralization than in uncut stands, whether the latter were composed of a single tree species or a combination of life-forms. Neither additional species richness nor replenishment of leached N augmented mineralization rates. The net rate at which N was supplied tended to be lowest in stands where demand for N was highest. Careful choice of species, coupled with low frequency of disturbance, can lead to maintenance of N within biomass and steady rates of within-system circulation, whereas pulses, whether caused by cutting

    Full Text Available We examined soil water use patterns of four model plant associations established in the North Caribbean lowlands of Costa Rica by comparing the stable hydrogen isotope composition, δD, in xylem sap and in soil water at different depths, under rainy and dry conditions. Four 5-year-old model plant associations composed of 2 tree species (Hyeronima alchorneoides and Cedrela odorata having different architecture and phenology were studied. Average tree height was 8.9 and 7.6 m, respectively. Each tree species was grown in monoculture and in polyculture with 2 perennial monocotyledons (Euterpe oleracea and Heliconia imbricata. Maximum rooting depth at the time of δD determination was ~ 2 m for almost all species. Most roots of all species were concentrated in the upper soil layers. Stomatal conductance to water vapor (gS was higher in the deciduous C. odorata than in the evergreen H. alchorneoides; within each species, gS did not differ when the trees were grown in mono or in polyculture. During the rainy season, gradients in soil water δD were not observed. Average rainy season xylem sap δD did not differ among members of the plant combinations tested (-30 ‰, and was more similar to δD values of shallow soil water. Under dry conditions, volumetric soil water content declined from 50 to ~ 35%, and modest gradients in soil water δD were observed. xylem sap δD obtained during dry conditions was significantly lower than rainy season values. xylem sap δD of plants growing in the four associations varied between -9 and -22‰, indicating that shallow water was predominantly absorbed during the dry period too. Differences in xylem sap δD of trees and monocots were also detected, but no significant patterns emerged. The results suggest that: a the plant associations examined extracted water predominantly from shallow soil layers (Examinamos los patrones de uso de agua del suelo de cuatro asociaciones vegetales establecidas en el Caribe norte de

    It is a long history the tale of the recognized asymmetries of the Earth. In 1600 William Gilbert (1544-1603) published De Magnete in which the North and South geomagnetic pole are described. In 1620 Francis Bacon (1561-1628) in the XXVIIth aphorism of the Novum Organum (second part) describes the southern tips of the continents, and many other asymmetries were later described. In 1975 Samuel Warren Carey (1911-2002) stated: Neither north and south, nor east and west are tectonically equivalent. A non exhaustive list of asymmetries of the Earth is: The magnetic polarity; The land-hemisphere and the water-hemisphere; Southern tips of the continents; Larger extension of expanding mid-oceanic ridges on the southern hemisphere; South-eastward trend of younger ages in the long Pacific seafloor volcanic chains; A larger width of the seafloor isochrones bands on the Nazca region; A pear-shaped Earth; etc. It is a few decades that the different slopes of the Wadati-Benioff zones oriented towards the east and west has been enclosed in the list. Under the Americas they have angles of about 30 degrees, while under the Pacific east coasts (Asia, Japan) the angles are steeper (Luyendyk, 1970; Isacks & Barazangi, 1977; and many others). The cause of this difference has been identified in the tidal drag that would cause a global shift of the lithosphere towards west - the so called westward drift (Bostrom, 1971; Stevenson & Turner, 1977; among others). This solution has been many times criticized on the basis of the irrelevance of the tidal forces with respect to viscous friction (Jordan, 1974; Ranalli, 2000; Caputo & Caputo, 2012). Moreover, a simplistic evaluation of the regime of the convective motion in the mantle and of the order of magnitude of the involved forces (viscous, buoyancy, inertial) hastily judges as negligible the role of the Coriolis effect in producing the observed slope differences of the Wadati-Benioff regions. Instead, it is possible to show that changing

    My name is Siobhan McDonald. I am a visual artist living and working in Dublin. My studio is based in The School of Science at University College Dublin where I was Artist in Residence 2013-2015. A fascination with time and the changeable nature of landmass has led to ongoing conversations with scientists and research institutions across the interweaving disciplines of botany, biology and geology. I am developing a body of work following a recent research trip to the North Pole where I studied the disappearing landscape of the Arctic. Prompted by my experience of the Arctic shelf receding, this new work addresses issues of the instability of the earth's materiality. The work is grounded in an investigation of material processes, exploring the dynamic forces that transform matter and energy. This project combines art and science in a fascinating exploration of one of the Earth's last relatively untouched wilderness areas - the High Arctic to bring audiences on journeys to both real and artistically re-imagined Arctic spaces. CRYSTALLINE'S pivotal process is collaboration: with The European Space Agency; curator Helen Carey; palaeontologist Prof. Jenny McElwain, UCD; and with composer Irene Buckley. CRYSTALLINE explores our desire to make corporeal contact with geological phenomena in Polar Regions. From January 2016, in my collaboration with Jenny McElwain, I will focus on the study of plants and atmospheres from the Arctic regions as far back as 400 million years ago, to explore the essential 'nature' that, invisible to the eye, acts as imaginary portholes into other times. This work will be informed by my arctic tracings of sounds and images recorded in the glaciers of this disappearing frozen landscape. In doing so, the urgencies around the tipping of natural balances in this fragile region will be revealed. The final work will emerge from my forthcoming residency at the ESA in spring 2016. Here I will conduct a series of workshops in ESA Madrid to work with

    Full Text Available Nowadays, the availability of national food cannot accommodate all the food needs of nation’s people, especially in each region. This current issue is caused by the absence of an effective arrangement, the absence of synchronization among state institutions, especially among the agricultural, trade and housing agencies, and the presence of an extreme climate change currently. In addition, the issues of the regeneration of farmers that have not shown any continuity that had been cut off among the younger generations led to the changes in the pattern of community life in the region. Therefore, based on the aforesaid issues, this paper aims at finding out on how the strategy and policy of food development in the local food availability in the midst of climate change today can be overcome by changing the mindset of consumptive to productive young generation through agricultural education, utilization of empty land which is available for planting food crops, empowerment of farmer groups, socialization of the local food potentials in East Nusa Tenggara. As a result, the food security can be realized and the region cannot be dependent its food needs on the other regions. Therefore, the writer attempts to formulate the strategy of food security developments from education aspects through the Dick & Carey development strategy. Food is an important and strategic commodity for the region because food is the basic human need that must be provided collectively by the government and society as mandated by the Acts No. 7 of 1996 on food. With respect to the Acts No. 7 of 1996 on food, it is stated that the Government organizes the regulation, guidance, control and supervision of the community, and organizes the process of production and supply, trade, distribution and in the same time, the Government also serves as a consumer that is entitled to adequate food, in terms of quantity and quality, safety, nutrition, variety, equity, and affordability by all

    The purpose of this research is to develop a cooperative learning model based on local wisdom (PKBKL) of Bali (Tri Pramana’s concept), for physical education, sport, and health learning in VII grade of Junior High School in Singaraja-Buleleng Bali. This research is the development research of the development design chosen refers to the development proposed by Dick and Carey. The development of model and learning devices was conducted through four stages, namely: (1) identification and needs analysis stage (2) the development of design and draft of PKBKL and RPP models, (3) testing stage (expert review, try out, and implementation). Small group try out was conducted on VII-3 grade of Undiksha Laboratory Junior High School in the academic year 2013/2014, large group try out was conducted on VIIb of Santo Paulus Junior High School Singaraja in the academic year 2014/2015, and the implementation of the model was conducted on three (3) schools namely SMPN 2 Singaraja, SMPN 3 Singaraja, and Undiksha laboratory Junior High School in the academic year 2014/2015. Data were collected using documentation, testing, non-testing, questionnaire, and observation. The data were analyzed descriptively. The findings of this research indicate that: (1) PKBKL model has met the criteria of the operation of a learning model namely: syntax, social system, principles of reaction, support system, as well as instructional and nurturing effects, (2) PKBKL model is a valid, practical, and effective model, (3) the practicality of the learning devices (RPP), is at the high category. Based on the research results, there are two things recommended: (1) in order that learning stages (syntax) of PKBKL model can be performed well, then teachers need to have an understanding of the cooperative learning model of Student Team Achievement Division (STAD) type and the concepts of scientifically approach well, (2) PKBKL model can be performed well on physical education, sport and health learning, if the

  7. Teaching science for conceptual change: Toward a proposed taxonomy of diagnostic teaching strategies to gauge students' personal science conceptions

    Shope, Richard Edwin, III

    Science instruction aims to ensure that students properly construct scientific knowledge so that each individual may play a role as a science literate citizen or as part of the science workforce (National Research Council, 1996, 2000). Students enter the classroom with a wide range of personal conceptions regarding science phenomena, often at variance with prevailing scientific views (Duschl, Hamilton, & Grandy, 1992; Hewson, 1992). The extensive misconceptions research literature emphasizes the importance of diagnosing students' initial understandings in order to gauge the accuracy and depth of what each student knows prior to instruction and then to use that information to adapt the teaching to address student needs. (Ausubel, 1968; Carey, 2000; Driver et al., 1985; Karplus & Thier, 1967; Mintzes, Wandersee, & Novak, 1998; Osborne & Freyberg, 1985; Project 2061, 1993; Strike & Posner, 1982, 1992; Vygotsky, 1934/1987). To gain such insight, teachers diagnose not only the content of the students' personal conceptions but also the thinking processes that produced them (Strike and Posner, 1992). Indeed, when teachers design opportunities for students to express their understanding, there is strong evidence that such diagnostic assessment also enhances science teaching and learning (Black & William, 1998). The functional knowledge of effective science teaching practice resides in the professional practitioners at the front lines---the science teachers in the classroom. Nevertheless, how teachers actually engage in the practice of diagnosis is not well documented. To help fill this gap, the researcher conducted a study of 16 sixth grade science classrooms in four Los Angeles area middle schools. Diagnostic teaching strategies were observed in action and then followed up by interviews with each teacher. Results showed that teachers use strategies that vary by the complexity of active student involvement, including pretests, strategic questions, interactive discussion

    approaches (direct vs. inverse evaluation, capillary vs. flow weighted pore radius). We will show the influence of the distinct evaluation procedures on the resulting effective macroporosity, as well as on the relationships between macropore radius and hydraulic conductivity (Moret and Arrúe, 2007) and pore fraction respectively (Carey et al., 2007). The infiltration measurements used in this study were obtained in a long-term tillage trial located in the semi-arid region of Eastern Austria. Measurements were taken five times over the vegetation period, starting immediately after tillage until harvest of the winter wheat crop. Three tillage systems were evaluated, being conventional tillage with plough, minimum tillage with chisel and no-tillage. Additional to infiltration measurements, also soil water content was monitored continuously by a capacitance probe in all three replicates of each tillage treatment in 10, 20 and 40 cm soil depth. Water content time series are used to derive flow velocity in the wet range by cross-correlation analysis (Wu et al., 1997). This effective parameter of water transmission will then be compared to the flow behaviour expected from the characterization of soil macroporosity. We will show that mainly in no-tillage systems large macropores contribute essentially to flow and therefore the decision on pore measure and evaluation procedure to be used leads to substantial differences. For a detailed comparison of tillage effects on soil hydraulic properties it is therefore essential to analyse the contribution of different tension infiltrometry based evaluation methods to explain effective water transmission through the complex porous network of the soil.

    Full Text Available Zoantharians are a group of cnidarians that are often found in association with marine invertebrates, including corals, in shallow and deep-sea environments. However, little is known about deep-sea zoantharian taxonomy, specificity and nature of their associations with their coral hosts. In this study, analyses of molecular data (mtDNA COI, 16S, and 12S rDNA coupled with ecological and morphological characteristics were used to examine zoantharian specimens associated with cold-water corals (CWC at depths between 110 and 800 m from seamounts and island slopes in the Azores region. The zoantharians examined were found living in association with stylasterids, antipatharians and octocorals. From the collected specimens, four new species were identified: (1 Epizoanthus martinsae sp. n. associated with the antipatharian Leiopathes sp.; (2 Parazoanthus aliceae sp. n. associated with the stylasterid Errina dabneyi (Pourtalès, 1871; (3 Zibrowius alberti sp. n. associated with octocorals of the family Primnoidae [Paracalyptrophora josephinae (Lindström, 1877] and the family Plexauridae (Dentomuricea aff. meteor Grasshoff, 1977; (4 Hurlizoanthus hirondelleae sp. n. associated with the primnoid octocoral Candidella imbricata (Johnson, 1862. In addition, based on newly collected material, morphological and molecular data and phylogenic reconstruction, the zoantharian Isozoanthus primnoidus Carreiro-Silva, Braga-Henriques, Sampaio, de Matos, Porteiro & Ocaña, 2011, associated with the primnoid octocoral Callogorgia verticillata (Pallas, 1766, was reclassified as Zibrowius primnoidus comb. nov. The zoantharians, Z. primnoidus comb. nov., Z. alberti sp. n., and H. hirondelleae sp. n. associated with octocorals showed evidence of a parasitic relationship, where the zoantharian progressively eliminates gorgonian tissue and uses the gorgonian axis for structure and support, and coral sclerites for protection. In contrast, the zoantharian P. aliceae sp. n

  14. Cornea procurement, preservation and transplantation

    Our experience on this subject is 40 years and we have seen the developments everywhere during this total period. Cornea procurement has been an unsurmountable problem in a large number of countries, mostly due to social and cultural reasons. The requirements for a simple eye bank to manage the supply for a local hospital are minimal. What is the most important is the donor base. In Sri Lanka nurtured in the traditions of Theravada Buddhism the donor base was easy to prepare. We had no difficulties with Christians and Hindus. For Muslims there are Fatwas in favour of donating eyes. But we always found them to be a reluctant group. But in predominantly Muslim countries, it is imperative that social workers should take up this issue, so those thousands may be helped. In all areas where attempts are made to procure comeas, it is important to have a day-and-night service available at short notice to collect any eyes offered. A trained technician with sterilised instruments to obtain eyes and blood sample must be available at a convenient location preferably in a large hospital. Even in places where the supply is infrequent, it is essential to have the readily-sterilised instruments to proceed to a donor site at short notice. To get eyes, general publicity in mass media alone is not sufficient. Such publicity makes people aware of the need for donor eyes and where a technician/doctor is available. What is more important is to canvass personally after a person has died For this purpose trained social workers may be employed, or the technician can do the motivation, as we do in Sri Lanka. Once eyes are removed, it is essential to pay careful attention to the appearance of the cadaver. It should not (and need not) cause any deformity as such event has a profound negative effect on the campaign. Many different preservation methods have been used over the years. Mc Carey-Kaufmann (MK) medium has been the standard for many years, and gives a life span of 4-5 days. The formula

Expansion is shown by the Asian and Australian trenches, from Kamchatka to the Marianas, and from Samoa to the tip of Macquarie Ridge south of New Zealand, that are mirror images of the western coasts of North and South America. This is clear evidence neither the Atlantic nor the Pacific Ocean existed 250 Ma when Earth was much smaller. In just 250 Ma external accretion and internal core expansion increased Earth's diameter from 7640 km to 12,735 km and increased total surface area to 361,060,000 sq. km, the area occupied by today's oceans-oceans that did not exist 250 Ma when Earth was slightly larger than Mars is today \\(6787 km\\). The fallacy of the nebular hypothesis did not become apparent until after Oliver and Isacks introduced the concept of subduction in 1967. Subduction was based on the false assumption that Earth's diameter is constant and unchanging, and spawned the theory of Plate Tectonics that "revolutionized" geophysics in a short period of time-a "revolution" destined for failure. Evidence is presented showing all solar bodies originate as comets \\(fragments of supernovae explosions\\) captured by the Sun that become meteoroids or asteroids by external accretion of meteorites and dust from over 370 known meteor streams.\\(Terentjeva, 1964\\) Accreation replaces the nebular hypothesis and rejuvenates Carey's Earth Expansion theory that, unfortunately, was pushed aside by plate tectonics because it lacked a plausible mechanism. However, expansion carries an ultimate threat to Mankind's tenure on Earth and exploration of Mars as the future home of Mankind takes on added significance.

This relative proximity has prevented star trackers and cameras on other X-ray astronomy satellites from locking onto guide stars and pointing steadily in the direction of Venus to perform such an observation. Venus was observed on Jan. 10, 2001, with the Advanced CCD Imaging Spectrometer (ACIS) detector plus the Low Energy Transmission Grating and on Jan. 13, 2001, with the ACIS alone. Other members of the team were Vadim Burwitz and Jakob Engelhauser, Max Planck Institute; Carey Lisse, University of Maryland, College Park; and Scott Wolk, Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass. These results were presented at this week's "New Visions of X-ray universe in the XMM-Newton and Chandra Era" symposium in Noordwijk, Netherlands. The Low Energy Transmission Grating was built by the Space Research Organization of the Netherlands and the Max Planck Institute, and the ACIS instrument was developed for NASA by The Pennsylvania State University, University Park, and the Massachusetts Institute of Technology (MIT), Cambridge.

Antes del drenaje de los humedales costeros para propósitos agrícolas, pantanos de agua dulce como los de la Laguna Cartagena, Laguna Guánica y Ciénaga El Anegado proveían hábitat a más de 1 00 especies de aves residentes y migratorias . Los humedales de las tierras altas del área central son el último refugio de la cotorra puertorriqueña, una especie en peligro de extinción. Aún los humedales del área metropolitana de San Juan (Laguna La Torrecilla, Torrecilla Baja, Laguna de Piñones hasta Punta Vacía Talega) proveen un hábitat excelente para la vida silvestre, mantienen criaderos de peces de alto valor económico y proveen recreación y oportunidades educativas a la población urbana.Treintiocho especies de vertebrados, moluscos y crustáceos, y 46 especies de aves, algunos raros o en peligro de extinción como la mariquita, el alcatraz, el pato dominicano, el pato silbón y la paloma cabeciblanca han sido observados en el área . También las playas asociadas con estos humedales urbanos proveen sitios de anidaje para las tortugas carey de concha y tinglar, ambas en peligro de extinción (Del Llano y otros, 1986).

  19. ‘I can touch him now’: Harry Potter as a Gothic Narrative of Trauma and Homoerotic Sexual Abuse

    Directory of Open Access Journals (Sweden)

    Full Text Available In this article I argue that the Harry Potter novels constitute a Gothic narrative about homoerotic child abuse. The various confrontations between Harry and the Dark Lord are interpreted as representing the unavoidable encounter with what Ruth Bienstock Anolik has defined as ‘the sexual Other’ infiltrating the Self in Gothic texts. Specifically, I examine the re-enactment of trauma in the narrative as a typical trope of the Gothic. Harry’s progressive acquisition of knowledge on his adversary is therefore interpreted as a metaphor for the gradual re-assertion of repressed traumatic memories on consciousness.Keywords: Harry Potter, trauma, repression, Gothic, abuseThe critical readings on J. K. Rowling’s Harry Potter novels hitherto published have mainly focused on the commercially-successful and worldwide consumerist phenomenon of the series and have specifically considered it as belonging to the literary genre of children literature (Carey 159; Rangwala 140; Nafici 209; Nikolajeva 240. We could, however, also inscribe the series into the Gothic genre. This is due to the use of many figures (such as the monster, locations (such as the castle, and tropes (such as the depiction of the story’s villain as a sexual threat or the theme of the return of the past that are typical of the Gothic genre. The novels begin with the murders of Lily and James Potter and the attempt on the life of Harry (Hook 91 and are then permeated by the “themes of evil, darkness, destruction and murder” (Patrick and Patrick 221. As some critics have noted, there are “numerous and horrendous instances of violence” (Taub and Servaty-Seib 22 throughout the series and death is one of the dominant themes of the narrative, which “moves from wonder, innocence, and comedy to fear, experience, and tragedy” (Behr 263. Secondly, many of the scenes of the seven novels are set in environments which are typically Gothic, as the following examples illustrate: the

    To measure retinol binding protein 4 (RBP4) levels in serum and bile and to analyze their relationship with insulin resistance, dyslipidemia or cholesterol saturation index (CSI).
 A total of 60 patients with gallstone were divided into a diabetes group (n=30) and a control group (n=30). The concentrations of RBP4 in serum and bile were detected by enzyme-linked immunosorbent assay (ELISA). Enzyme colorimetric method was used to measure the concentration of biliary cholesterol, bile acid and phospholipid. Biliary CSI was calculated by Carey table. Partial correlation and multiple linear regression analysis were used to evaluate the correlation between the RBP4 levels in serum or bile and the above indexes.
 The RBP4 concentrations in serum and bile in the diabetes group were significantly elevated compared with those in the control group (both Ptriglyceride (TG), serum high-density lipoprotein (HDL), bile TBA, bile total cholesterol (TC) , bile phospholipids and bile CSI between the 2 groups (all P>0.05); but the serum TC, low density lipoprotein (LDL), fasting blood glucose (FBG), fasting insulin (FINS), and homeostasis model assessment for insulin resistance (HOMA-IR) in the diabetes group were significantly increased compared to those in the control group (all Pindex (BMI), waist circumference (WC), FINS, FBG, TC, LDL and HOMA-IR (r=0.283, 0.405, 0.685, 0.667, 0.553, 0.424 and 0.735, respectively), and the serum RBP4 was also positively correlated with the WC, FINS, FBG, TC, LDL and HOMA-IR (r=0.317, 0.734, 0.609, 0.528, 0.386 and 0.751, respectively). Stepwise multivariate linear regression analysis suggested that the HOMA-IR, BMI and WC were independently correlated with the level of bile RBP4 (multiple regression equation: Ybile RBP4=2.372XHOMA-IR+0.420XBMI+0.178XWC-26.813), and the serum RBP4 level was correlated with the HOMA-IR and WC independently (multiple regression equation: Yserum RBP4=2.832XHOMA-IR +0.235XWC-20.128).

    Full Text Available Introduction: Canola (Brassica napus L. is one of the prominent oil seed plants in Iran. This plant has good agricultural and food nourishment properties, such as resistant to drought, cold and salinity stresses and low level of cholesterol. Cabbage waxy aphid Brevicorynebrassicae (L. is the most important and cosmopolitan pest of cruciferous crops. This aphid is reduced 9 to 77% grain yields and up to 11% oil content. Developing environmental-friendly methods, such as deploying insect-resistant varieties to pest control was advised by scientists. Resistant varieties decrease production costs and can be integrated with other pest control policies in IPM programs. In a greenhouse experiment plants of cabbage, cauliflower wassusceptible host plant and broccoli, turnip, rapeseed, showed resistance to cabbage aphid. With the aim of identifying the existence of resistance resources, a laboratory study was conducted to evaluate the effects of seven canola genotypes on biological parameters of cabbage aphid. Detected resistant variety could be used as a resistance source. Material and Methods: In order to resistancy evaluation of canola, genotypes contain “RGS”,“Hyola-308”,“Hyola-401” and “Sarigol” to cabbage aphid, two experiments was conducted under field and greenhouse conditions in Kahriz region of West Azerbaijan province in 2010.In this study infestation index and tolerance in Field conditions and antibiosis study in greenhouse conditions was evaluated.To study antibiosis, genotypes were planted in pots with 10 replications based on completely random design and cabbage aphid population intrinsic rate of increase (rm was calculated. As followed: (Lotka 1924: 1= other population parameters computed by Carey (1993 method.

    by confirming the degradation of cement (carbonation) along the casing-cement interface. The ultrasonic image maps also clearly identify the control lines and monitoring technology attached to the outside of the of the long-string casing on each well studied. The control lines appear as microdebonded or fluid filled vertical features implying that they could act as leakage pathways. The sidewall core through the control line at 10380 ft confirms that CO2 is migrating along the control line with heavily carbonated cement at the control line interface. LA-ICP-MS and XRD on formation interface of the sidewall cores collected in both wells indicates that CO2 is also moving of the cement-formation interface. LA-ICP-MS and XRD indicate that the amount carbonation in the center of the cores was less than the carbonation at the interfaces. Indicating that CO2 is reaching the center of the cores by diffusing in from the interfaces and not migrating up from the reservoir though the porous matrix of the cement. This agrees with Duguid et al. [5] and Carey et al. [1] who have found that the interfaces in the well are more conductive than the porous network of the cement. Both the materials used to construct the well and the decision to attach monitoring technology to the outside of the well may have contributed to the migration of CO2 along the interfaces. Careful consideration should be given to material selection to ensure that it does not degrade when in contact with the fluids in the reservoir and overlying strata. The addition of the control line on the outside of the casing complicated the cement placement and likely caused no cement to bond to the casing adjacent to the control line leading out of the reservoir. Further study of other wells with external lines should be conducted to see of the results of the construction of CFU31-F2 and -F3 is normal or an exception.

    previous work with poorer resolution indicated no polarization. Most importantly they recognized that the implied radial field "suggests that the magnetic field has been carried out with the expansion of the supernova envelope, and...[they] observe[d] polarized radiation associated with a component which has been stretched out in the radial direction during the expansion of the shell." This landmark paper led the way for later polarimetric studies of both galactic and extragalactic radio sources. Observations two decades later with the VLA (the world's most powerful, synthesis radio telescope with a quarter million pixels to each one of Connie's), substantiated most or all of his early conclusions, and was a tribute to his pioneering effort. The NRL group was later involved in discoveries about the variability of interstellar water and SiO masers, the structure of molecular clouds and star forming regions, the development of techniques for precision time transfer, remote sensing of the ocean and atmosphere, and much else, but in the aforementioned radio astronomy work, Connie Mayer had no peer. A colleague remarked, "Connie was among the last of the scientist-engineers who built their own equipment, performed their own experiments, and also interpreted the results into paradigm shifting science." Connie was a rare and noble example of natural modesty, becoming uncomfortable if anyone praised him. After his death, his wife found many awards that he had received but never framed nor told her about. He joked that he did not want a formal funeral "with a lot of people getting up and mouthing off about me." He received full military honor services at Arlington National Cemetery, but was cremated as per his wishes. He is survived by Carey Whitehead Mayer, his wife of fifty-six years, and their daughter, Carolyn Elizabeth Mayer. Their son, John, died in 1978.

    ; Marcot, 2003). For example, by puncturing bark and fragmenting sapwood, woodpeckers create sites favorable for wood-decaying organisms (Farris et al., 2004), which in turn create habitat for other species and facilitate nutrient cycling. Small mammals that use down wood for cover function in the dispersal of plant seeds and fungal spores (Carey et al., 1999). Resident cavitynesting birds may regulate insect populations by preying on overwintering arthropods (Jackson, 1979; Kroll and Fleet, 1979). These examples illustrate how dead wood not only directly provides habitat for a large number of wildlife species, but also forms the foundation of functional webs that critically influence forest ecosystems (Marcot, 2002; Marcot, 2003). The important and far-reaching implications of management of decaying wood highlight the need for conservation of dead-wood resources in managed forests. Consideration of the key ecological functions of species associated with dead wood can help guide management of dead wood in a framework consistent with the paradigm of ecosystem management (Marcot and Vander Heyden, 2001; Marcot, 2002.) As more information is revealed about the ecological and habitat values of decaying wood, concern has increased over a reduction in the current amounts of dead wood relative to historic levels (Ohmann and Waddell, 2002). Past management practices have tended to severely reduce amounts of dead wood throughout all stages of forest development (Hansen et al., 1991). The large amounts of legacy wood that characterize young post-disturbance forests are not realized in managed stands, because most of the wood volume is removed at harvest for economic and safety reasons. Mid-rotation thinning is used to “salvage” some mortality that might otherwise occur due to suppression, so fewer snags are recruited in mid-seral stages. Harvest rotations of 80 years or less truncate tree size in managed stands, and thus limit the production of large-diameter wood. As a
