Full Text Available One of the actual elementary biologic principles of the introduction of queen is that the recipient co­lo­ny has to be queenless. We accidentally found that a queen can be accepted also in queenright co­lo­ny with using of the queen excluder. Therefore, we conducted two experiments with the introduction of queen in queenright colony.Under defined conditions of the experiment and with application of the queen excluder as a separator of queens we successfully introduced queen in the queenright colony. This result is discussed in relation to the general principle that a queen should be introduced only in a queenless colony. It is possible that there are some exceptions advert to the existence of some unknown biologic patterns in the honey bee biology and pheromones.

Enhancing the interfaces among schools, colleges, universities, and industry

Burns, D.

2006-01-01

'Full text:' The 2005 Rae Report on higher education in Ontario recommended that the Provincial government 'reaffirm the mandate of colleges to focus on occupational education and labour market needs, while continuing to allow applied degrees and institutional evolution. Mandate colleges to reach out to the fifty percent of high school students not going on to further studies...' Another recommendation was 'encourage the distinct evolution of each institution (i.e. colleges and universities) and promote differentiation through the tuition framework, accountability arrangements and the design of the Province's funding formula. At the same time, require that colleges and universities recognize each others' related programming to create clear and efficient pathways for students.' Implementing these recommendations requires major changes in the interfaces among schools, colleges, universities and industry, and also in the attitudes of parents, the teaching profession, and employers.

Seeley, Thomas D; Tarpy, David R

2006-01-01

Most species of social insects have singly mated queens, but in some species each queen mates with numerous males to create a colony with a genetically diverse worker force. The adaptive significance of polyandry by social insect queens remains an evolutionary puzzle. Using the honeybee (Apis mellifera), we tested the hypothesis that polyandry improves a colony's resistance to disease. We established colonies headed by queens that had been artificially inseminated by either one or 10 drones. Later, we inoculated these colonies with spores of Paenibacillus larvae, the bacterium that causes a highly virulent disease of honeybee larvae (American foulbrood). We found that, on average, colonies headed by multiple-drone inseminated queens had markedly lower disease intensity and higher colony strength at the end of the summer relative to colonies headed by single-drone inseminated queens. These findings support the hypothesis that polyandry by social insect queens is an adaptation to counter disease within their colonies. PMID:17015336

2018-02-01

Understanding the factors that affect animal dispersal behavior is important from both fundamental and applied perspectives. Dispersal can have clear evolutionary and ecological consequences, but for nonnative insect pests, dispersal capacity can also help to explain invasion success. Vespula germanica is a social wasp that, in the last century, has successfully invaded several regions of the world, showing one of the highest spread rates reported for a nonnative insect. In contrast with nonsocial wasps, in social species, queens are responsible for population redistribution and spread, as workers are sterile. For V. germanica, it has been observed that queen flight is limited to 2 distinct periods: early autumn, when new queens leave the nest to mate and find sheltered places in which to hibernate, and spring when new colonies are founded. Our aim was to study the flight behavior of V. germanica queens by focusing on the different periods in which dispersal occurs, characterizing as well the potential contribution of queen flight (i.e., distance) to the observed geographical spread. Our results suggest that the distances flown by nonoverwintered queens is greater than that flown by overwintered individuals, suggesting that the main queen dispersal events would occur before queens enter hibernation. This could relate to a behavioral trait of the queens to avoid the inbreeding with related drones. Additionally, given the short distances flown and remarkable geographical spread observed, we provide evidence showing that queen dispersal by flight is likely to contribute proportionately less to population spread than human-aided factors. © 2016 Institute of Zoology, Chinese Academy of Sciences.

Changes in the cuticular hydrocarbon profile of the slave-maker ant queen, Polyergus breviceps emery, after killing a Formica host queen (Hymenoptera: Formicidae).

Johnson, C A; Vander Meer, R K; Lavine, B

2001-09-01

Queens of the slave-maker ant, Polyergus breviceps, take over nests of their Formica host species by fatally attacking the resident queen. As workers only begin grooming the P. breviceps queen once she has ceased her attack, we investigated whether a change in parasite queen chemistry may account for the change in worker behavior. Cuticular hydrocarbon profiles of newly mated P. breviceps queens and of queens of their two Formica host species were found to be species-specific. Profiles of newly mated P. breviceps queens that had attacked a Formica queen, however, were virtually identical to the queen profile of the species killed. Mass spectral analysis revealed that the hydrocarbons on the cuticles of newly mated P. breviceps changed from primarily normal alkanes to methyl and di-methyl branched alkanes after attacks. The results suggest that cuticular compounds from the host queen were transferred to the parasite queen during their aggressive interaction.

Queen Quality and the Impact of Honey Bee Diseases on Queen Health: Potential for Interactions between Two Major Threats to Colony Health

Directory of Open Access Journals (Sweden)

Esmaeil Amiri

2017-05-01

Full Text Available Western honey bees, Apis mellifera, live in highly eusocial colonies that are each typically headed by a single queen. The queen is the sole reproductive female in a healthy colony, and because long-term colony survival depends on her ability to produce a large number of offspring, queen health is essential for colony success. Honey bees have recently been experiencing considerable declines in colony health. Among a number of biotic and abiotic factors known to impact colony health, disease and queen failure are repeatedly reported as important factors underlying colony losses. Surprisingly, there are relatively few studies on the relationship and interaction between honey bee diseases and queen quality. It is critical to understand the negative impacts of pests and pathogens on queen health, how queen problems might enable disease, and how both factors influence colony health. Here, we review the current literature on queen reproductive potential and the impacts of honey bee parasites and pathogens on queens. We conclude by highlighting gaps in our knowledge on the combination of disease and queen failure to provide a perspective and prioritize further research to mitigate disease, improve queen quality, and ensure colony health.

College student bereavement, scholarship, and the university: a call for university engagement.

Science.gov (United States)

Balk, D E

2001-01-01

The prevalence of bereavement among traditional-aged college students should impel universities to assist bereaved students on their campuses. Dealing with bereavement can not only challenge a college student's completing the developmental tasks that our society sets for the later adolescent years, but also imperil the student's remaining in school and graduating. It is in the best interests of the university to develop and implement a variety of effective interventions to assist bereaved students. The author argues that universities are communities devoted to scholarly endeavors and should explicitly incorporate the dimension of compassion and caring. An abbreviated case study is used to illustrate the situations in which one grieving student found herself when she returned to school following the death of her father. A call is made for greater university engagement by forming a university-based bereavement center to coordinate and conduct coherent inquiry that fulfills the scholarly functions of discovery, application, and instruction. Four specific actions for a bereavement center are to train nonbereaved students to provide peer support, to provide structured interventions for college students at risk of bereavement complications, to raise consciousness about bereavement on the university campus, and to conduct research into various bereavement populations and bereavement topics.

Chronic Bee Paralysis Virus in Honeybee Queens

2014-01-01

Chronic bee paralysis virus (CBPV) is known as a disease of worker honey bees. To investigate pathogenesis of the CBPV on the queen, the sole reproductive individual in a colony, we conducted experiments regarding the susceptibility of queens to CBPV. Results from susceptibility experiment showed...... a similar disease progress in the queens compared to worker bees after infection. Infected queens exhibit symptoms by Day 6 post infection and virus levels reach 1011 copies per head. In a transmission experiment we showed that social interactions may affect the disease progression. Queens with forced...... contact to symptomatic worker bees acquired an overt infection with up to 1011 virus copies per head in six days. In contrast, queens in contact with symptomatic worker bees, but with a chance to receive food from healthy bees outside the cage appeared healthy. The virus loads did not exceed 107...

Effects of insemination quantity on honey bee queen physiology.

Directory of Open Access Journals (Sweden)

Freddie-Jeanne Richard

2007-10-01

Full Text Available Mating has profound effects on the physiology and behavior of female insects, and in honey bee (Apis mellifera queens, these changes are permanent. Queens mate with multiple males during a brief period in their early adult lives, and shortly thereafter they initiate egg-laying. Furthermore, the pheromone profiles of mated queens differ from those of virgins, and these pheromones regulate many different aspects of worker behavior and colony organization. While it is clear that mating causes dramatic changes in queens, it is unclear if mating number has more subtle effects on queen physiology or queen-worker interactions; indeed, the effect of multiple matings on female insect physiology has not been broadly addressed. Because it is not possible to control the natural mating behavior of queens, we used instrumental insemination and compared queens inseminated with semen from either a single drone (single-drone inseminated, or SDI or 10 drones (multi-drone inseminated, or MDI. We used observation hives to monitor attraction of workers to SDI or MDI queens in colonies, and cage studies to monitor the attraction of workers to virgin, SDI, and MDI queen mandibular gland extracts (the main source of queen pheromone. The chemical profiles of the mandibular glands of virgin, SDI, and MDI queens were characterized using GC-MS. Finally, we measured brain expression levels in SDI and MDI queens of a gene associated with phototaxis in worker honey bees (Amfor. Here, we demonstrate for the first time that insemination quantity significantly affects mandibular gland chemical profiles, queen-worker interactions, and brain gene expression. Further research will be necessary to elucidate the mechanistic bases for these effects: insemination volume, sperm and seminal protein quantity, and genetic diversity of the sperm may all be important factors contributing to this profound change in honey bee queen physiology, queen behavior, and social interactions in the

Stimulating natural supersedure of honeybee queens, Apis mellifera

NARCIS (Netherlands)

Hendriksma, H.P.; Calis, J.N.M.; Boot, W.J.

2004-01-01

When a honeybee queen starts to fail, she is often superseded by a young queen that takes over reproduction inside the colony. Natural supersedure in winter leads to an unfertilised young queen and colony loss. To reduce these losses we tried to stimulate supersedure of queens earlier in the season.

Effects of neonicotinoid imidacloprid exposure on bumble bee (Hymenoptera: Apidae) queen survival and nest initiation.

Science.gov (United States)

Wu-Smart, Judy; Spivak, Marla

2018-02-08

Neonicotinoids are highly toxic to insects and may systemically translocate to nectar and pollen of plants where foraging bees may become exposed. Exposure to neonicotinoids can induce detrimental sublethal effects on individual and colonies of bees and may have long-term impacts, such as impaired foraging, reduced longevity, and reduced brood care or production. Less well-studied are the potential effects on queen bumble bees that may become exposed while foraging in the spring during colony initiation. This study assessed queen survival and nest founding in caged bumble bees [Bombus impatiens (Cresson) (Hymenoptera: Apidae)] after chronic (18-d) dietary exposure of imidacloprid in syrup (1, 5, 10, and 25 ppb) and pollen (0.3, 1.7, 3.3, and 8.3 ppb), paired respectively. Here we show some mortality in queens exposed at all doses even as low as 1 ppb, and, compared with untreated queens, significantly reduced survival of treated queens at the two highest doses. Queens that survived initial imidacloprid exposure commenced nest initiation; however, they exhibited dose-dependent delay in egg-laying and emergence of worker brood. Furthermore, imidacloprid treatment affected other parameters such as nest and queen weight. This study is the first to show direct impacts of imidacloprid at field-relevant levels on individual B. impatiens queen survival and nest founding, indicating that bumble bee queens are particularly sensitive to neonicotinoids when directly exposed. This study also helps focus pesticide risk mitigation efforts and highlights the importance of reducing exposure rates in the early spring when bumble bee queens, and other wild bees are foraging and initiating nests. © The Author(s) 2017.

Colony strength and queen replacement in Melipona marginata (Apidae: Meliponini

Directory of Open Access Journals (Sweden)

A. de M. P. Kleinert

Full Text Available Physogastric queens of Melipona marginata were removed from their colonies in order to verify the acceptance of a new queen by workers. Colony strength was evaluated according to queen oviposition rate and comb diameters. Replacement was observed seven times. Its occurrence and speed related positively to colony strength, independently of queen's age. In weak colonies, queen replacement was observed only once, following colony population increase that occurred after introduction of combs from another colony. Worker oviposition after queen removal was observed three times: in a strong colony with virgin queens and males, and in two of the weak colonies. In the first two or three days of new queen oviposition, during which most of the eggs were eaten by the queen, worker oviposition preceded almost all provisioning and oviposition processes (POPs. After this period, worker oviposition decreased until it reached around 25% of the POPs. Daily oviposition rate of young queens decreased or was even interrupted by hatching of their first brood.

Adopting a blended approach to learning: Experiences from Radiography at Queen Margaret University, Edinburgh

International Nuclear Information System (INIS)

Cockbain, M.M.; Blyth, C.M.; Bovill, C.; Morss, K.

2009-01-01

The perspective of the radiography teaching team at Queen Margaret University (QMU) was that a transmission mode of programme delivery was sub-optimal in helping students to learn and make links between theory and practice. Programme redesign adopted a blended learning approach with both face-to-face and online learning aimed at enhancing the students' control over their own learning. Online tasks within Web Classroom Tools (WebCT) were used as an integral part of careful programme design, which resulted in a programme enabling synthesis of the skills, knowledge and competencies acquired in the academic and clinical environments. With the move towards a more learner-centred, blended educational experience for the students the lecturers' role shifted to that of facilitator with WebCT providing the tutor with a more transparent view of student learning. Lecturers plan learning activities that build upon the skills students have developed through learning in groups, online and in class. The explicit connections that now exist between the academic programme and the opportunities for applying knowledge in practice allow students to engage more deeply in their learning.

Fierro, Macario M; Cruz-López, Leopoldo; Sánchez, Daniel; Villanueva-Gutiérrez, Rogel; Vandame, Remy

2011-11-01

Tetragonisca angustula mating occurs during the virgin queen nuptial flight, usually in the presence of a drone congregation area (DCA). The presence of virgin queen pheromone is considered the trigger for DCA establishment, although this has not been demonstrated experimentally. We established meliponaries, in different habitats, with T. angustula virgin queens during the main drone reproduction period. Eight DCAs were observed in urban areas, and all established outside or near colonies containing at least one virgin queen. The accumulation of drones in the DCAs occurred from 08:00 to 18:00 h and over 3-35 days. The number of drones in DCAs ranged from 60 to 2,000. In field trials, drones were attracted to virgin queens and also, unexpectedly, to physogastric queens. Volatiles collected from both virgin and physogastric queens elicited strong electoantennogram (EAG) responses from drones. Virgin and physogastric queen volatiles were qualitatively similar, but quantitatively different, in chemical composition. The queen's abdomen was the principal source of these compounds. Isopropyl hexanoate (IPH), the most abundant compound in virgin queen volatiles and one of the most abundant in physogastric queen volatiles, was identified as one of the compounds that elicited EAG responses and was demonstrated to attract drones in a field test.

Atoms against the universe

In Woody Allen's masterpiece Annie Hall the main character is worried about the expansion of the universe. Indeed, during a childhood visit to his psychiatrist, his mother admonishes him: ''You're here in Brooklyn! Brooklyn is not expanding!''. But is that really true? Relativists have attacked this naive question many times and have arrived at different answers. New light has now been thrown on the subject by William Bonnor from Queen Mary and Westfield College in London by considering the influence of the expanding universe on the size of the hydrogen atom (Class. Quantum Grav. 1999 16 1313). According to Bonner's calculations we can conclude that the cosmic expansion does not affect human-scale objects like laboratories and our bodies. In this article the authors explain the reasoning behind this research and its thought provoking consequences. (UK)

Aleš Gregorc

2012-01-01

Full Text Available Viral infection could have an impact on the success of queen rearing and a potential effect on reduced queen quality. Newly mated honey bee (Apis mellifera carnica queens were collected from mating nuclei in queen rearing operations in Slovenia. Altogether, 81 queens were sampled from 27 rearing apiaries in 2006 and 72 queens from 24 apiaries in 2008. Queens were analysed for the presence of four viruses: acute bee paralysis virus (ABPV, black queen cell virus (BQCV, sacbrood virus (SBV and deformed wing virus (DWV by using reverse transcription polymerase chain reaction (RT-PCR. In 2006, 12%, 9% and 1% prevalence was found for ABPV, DWV and SBV, respectively; BQCV was not detected. Two years later, DWV, BQCV, SBV and ABPV were detected in 58%, 24%, 11% and 10% bee queens, respectively. In 2006, fourteen out of twenty-seven apaiaries were virus free, whereas in 2008 only three out of twenty-four apiaries were virus free. This is the first evidence of virus infection occurring in newly mated queens from mating nuclei in rearing apiaries. The possible impacts of queen rearing technology and epidemiological influences on virus infection are discussed in this study.

Population and colony structure and morphometrics in the queen dimorphic little black ant, Monomorium sp. AZ-02, with a review of queen phenotypes in the genus Monomorium.

Directory of Open Access Journals (Sweden)

Robert A Johnson

Full Text Available The North American little black ant, Monomorium sp. AZ-02 (subfamily Myrmicinae, displays a dimorphism that consists of alate (winged and ergatoid (wingless queens. Surveys at our field site in southcentral Arizona, USA, demonstrated that only one queen phenotype (alate or ergatoid occurred in each colony during the season in which reproductive sexuals were produced. A morphometric analysis demonstrated that ergatoid queens retained all specialized anatomical features of alate queens (except for wings, and that they were significantly smaller and had a lower mass than alate queens. Using eight morphological characters, a discriminant analysis correctly categorized all queens (40 of 40 of both phenotypes. A molecular phylogeny using 420 base pairs of the mitochondrial gene cytochrome oxidase I demonstrated that alate and ergatoid queens are two alternative phenotypes within the species; both phenotypes were intermixed on our phylogeny, and both phenotypes often displayed the same haplotype. A survey of the genus Monomorium (358 species found that wingless queens (ergatoid queens, brachypterous queens occur in 42 of 137 species (30.6% in which the queen has been described. These wingless queen species are geographically and taxonomically widespread as they occur on several continents and in eight species groups, suggesting that winglessness probably arose independently on many occasions in the genus.

D'Ettorre, Patrizia; Kellner, K.; Delabie, J. H. C.

2005-01-01

In the ant Pachycondyla villosa, new colonies are usually started cooperatively by two or more young queens who establish a dominance order with a division of labour. Co-founding can lead to primary polygyny, where queens stay together after workers have emerged. Here we show that two queens...... these were attacked and sometimes killed in queen associations. The removal of dominant alpha queens from three-queen associations resulted in beta queens obtaining the dominant role and sometimes the destruction of the existing eggs. It appears that two queens suffice for a successful association...

College Student Samples Are Not Always Equivalent: The Magnitude of Personality Differences Across Colleges and Universities.

Science.gov (United States)

Corker, Katherine S; Donnellan, M Brent; Kim, Su Yeong; Schwartz, Seth J; Zamboanga, Byron L

2017-04-01

This research examined the magnitude of personality differences across different colleges and universities to understand (a) how much students at different colleges vary from one another and (b) whether there are site-level variables that can explain observed differences. Nearly 8,600 students at 30 colleges and universities completed a Big Five personality trait measure. Site-level information was obtained from the Integrated Postsecondary Education System database (U.S. Department of Education). Multilevel models revealed that each of the Big Five traits showed significant between-site variability, even after accounting for individual-level demographic differences. Some site-level variables (e.g., enrollment size, requiring letters of recommendation) explained between-site differences in traits, but many tests were not statistically significant. Student samples at different universities differed in terms of average levels of Big Five personality domains. This raises the possibility that personality differences may explain differences in research results obtained when studying students at different colleges and universities. Furthermore, results suggest that research that compares findings for only a few sites (e.g., much cross-cultural research) runs the risk of overgeneralizing differences between specific samples to broader group differences. These results underscore the value of multisite collaborative research efforts to enhance psychological research. © 2015 Wiley Periodicals, Inc.

Co-founding ant queens prevent disease by performing prophylactic undertaking behaviour.

Science.gov (United States)

Pull, Christopher D; Cremer, Sylvia

2017-10-13

Social insects form densely crowded societies in environments with high pathogen loads, but have evolved collective defences that mitigate the impact of disease. However, colony-founding queens lack this protection and suffer high rates of mortality. The impact of pathogens may be exacerbated in species where queens found colonies together, as healthy individuals may contract pathogens from infectious co-founders. Therefore, we tested whether ant queens avoid founding colonies with pathogen-exposed conspecifics and how they might limit disease transmission from infectious individuals. Using Lasius niger queens and a naturally infecting fungal pathogen Metarhizium brunneum, we observed that queens were equally likely to found colonies with another pathogen-exposed or sham-treated queen. However, when one queen died, the surviving individual performed biting, burial and removal of the corpse. These undertaking behaviours were performed prophylactically, i.e. targeted equally towards non-infected and infected corpses, as well as carried out before infected corpses became infectious. Biting and burial reduced the risk of the queens contracting and dying from disease from an infectious corpse of a dead co-foundress. We show that co-founding ant queens express undertaking behaviours that, in mature colonies, are performed exclusively by workers. Such infection avoidance behaviours act before the queens can contract the disease and will therefore improve the overall chance of colony founding success in ant queens.

Immunosuppression in Honeybee Queens by the Neonicotinoids Thiacloprid and Clothianidin.

2017-07-05

Queen health is crucial to colony survival of honeybees, since reproduction and colony growth rely solely on the queen. Queen failure is considered a relevant cause of colony losses, yet few data exist concerning effects of environmental stressors on queens. Here we demonstrate for the first time that exposure to field-realistic concentrations of neonicotinoid pesticides can severely affect the immunocompetence of queens of western honeybees (Apis mellifera L.). In young queens exposed to thiacloprid (200 µg/l or 2000 µg/l) or clothianidin (10 µg/l or 50 µg/l), the total hemocyte number and the proportion of active, differentiated hemocytes was significantly reduced. Moreover, functional aspects of the immune defence namely the wound healing/melanisation response, as well as the antimicrobial activity of the hemolymph were impaired. Our results demonstrate that neonicotinoid insecticides can negatively affect the immunocompetence of queens, possibly leading to an impaired disease resistance capacity.

Intraspecific queen parasitism in a highly eusocial bee

Wenseleers, Tom; Alves, Denise A.; Francoy, Tiago M.; Billen, Johan; Imperatriz-Fonseca, Vera L.

2011-01-01

Insect societies are well-known for their advanced cooperation, but their colonies are also vulnerable to reproductive parasitism. Here, we present a novel example of an intraspecific social parasitism in a highly eusocial bee, the stingless bee Melipona scutellaris. In particular, we provide genetic evidence which shows that, upon loss of the mother queen, many colonies are invaded by unrelated queens that fly in from unrelated hives nearby. The reasons for the occurrence of this surprising form of social parasitism may be linked to the fact that unlike honeybees, Melipona bees produce new queens in great excess of colony needs, and that this exerts much greater selection on queens to seek alternative reproductive options, such as by taking over other nests. Overall, our results are the first to demonstrate that queens in highly eusocial bees can found colonies not only via supersedure or swarming, but also by infiltrating and taking over other unrelated nests.

Virgin queen attraction toward males in honey bees.

Science.gov (United States)

Bastin, Florian; Cholé, Hanna; Lafon, Grégory; Sandoz, Jean-Christophe

2017-07-24

Although the honeybee is a crucial agricultural agent and a prominent scientific model organism, crucial aspects of its reproductive behaviour are still unknown. During the mating season, honeybee males, the drones, gather in congregations 10-40 m above ground. Converging evidence suggests that drones emit a pheromone that can attract other drones, thereby increasing the size of the congregation. Virgin queens join the vicinity of the congregation after it has formed, and mate with as many as 20 males in mid-air. It is still unclear which sensory cues help virgin queens find drone congregations in the first place. Beside visual cues for long-range orientation, queens may use olfactory cues. We thus tested virgin queens' olfactory orientation on a walking simulator in which they have full control over odour stimulation. We show that sexually-mature virgin queens are attracted to the odour bouquet from a group of living drones. They are not attracted to the bouquet from a group of workers. In addition, non-sexually receptive females (workers) of the same age are not attracted to the drone odour bouquet. Interpreted in the context of mating, these results may suggest that virgin queens use volatile olfactory cues from the drones to find the congregations.

Queen pheromones: The chemical crown governing insect social life.

Science.gov (United States)

Holman, Luke

2010-11-01

Group-living species produce signals that alter the behavior and even the physiology of their social partners. Social insects possess especially sophisticated chemical communication systems that govern every aspect of colony life, including the defining feature of eusociality: reproductive division of labor. Current evidence hints at the central importance of queen pheromones, but progress has been hindered by the fact that such pheromones have only been isolated in honeybees. In a pair of papers on the ant Lasius niger, we identified and investigated a queen pheromone regulating worker sterility. The cuticular hydrocarbon 3-methylhentriacontane (3-MeC(31)) is correlated with queen maturity and fecundity and workers are also more likely to execute surplus queens that have low amounts of this chemical. Experiments with synthetic 3-MeC(31) found that it inhibits ovarian development in queenless workers and lowers worker aggression towards objects coated with it. Production of 3-MeC(31) by queens was depressed by an experimental immune challenge, and the same chemical was abundant on queenlaid eggs, suggesting that the workers' responses to the queen are conditional on her health and fecundity. Together with other studies, these results indicate that queen pheromones are honest signals of quality that simultaneously regulate multiple social behaviors.

Queen Size Variation in the Ponerine Ant Ponera coarctata (Hymenoptera: Formicidae

Directory of Open Access Journals (Sweden)

1995-01-01

Full Text Available Queens of Ponera coarctata show a pronounced variation in size as measured by ommatidia number and Weber's alitrunk length. Isometric size variation and the normal distribution of size categories indicate that, despite these differences, only one queen morph exists. Queen size varies less within colonies than between colonies, and thus appears to be colony specific. Ovary length apparently varies with queen size. Similar size variations as in queens also occured in males, but not in workers.

Does the queen win it all? Queen-worker conflict over male production in the bumblebee, Bombus terrestris

Science.gov (United States)

Alaux, Cédric; Savarit, Fabrice; Jaisson, Pierre; Hefetz, Abraham

Social insects provide a useful model for studying the evolutionary balance between cooperation and conflict linked to genetic structure. We investigated the outcome of this conflict in the bumblebee, Bombus terrestris, whose annual colony life cycle is characterized by overt competition over male production. We established artificial colonies composed of a queen and unrelated workers by daily exchange of callow workers between colony pairs of distinct genetic make-up. Using microsatellite analysis, this procedure allowed an exact calculation of the proportion of worker-derived males. The development and social behavior of these artificial colonies were similar to those of normal colonies. Despite a high worker reproduction attempt (63.8% of workers had developed ovaries and 38.4% were egg-layers), we found that on average 95% of the males produced during the competition phase (CPh) were queen-derived. However, in four colonies, queen death resulted in a considerable amount of worker-derived male production. The different putative ultimate causes of this efficient control by the queen are discussed, and we suggest a possible scenario of an evolutionary arms race that may occur between these two female castes.

Full Text Available While observing: non-acceptance, frequent replacements, and reduced performance in honey bee (Apis mellifera ligustica queens, we were induced to analyse a certain number of queens to detect the causes. For this purpose, 99 newly mated queens were bought from 20 Italian queen breeders. In addition, 109 older or at-the-end-of-their-career queens, that showed poor productivity, were collected from honey production hives throughout Italy. All the queens were dissected to check the status of their reproductive system and/or the presence of various anomalies and diseases.

Late-life depression and the death of Queen Victoria.

Science.gov (United States)

Abrams, Robert C

2010-12-01

The objective of this study was to evaluate relationships between the death of Queen Victoria and the depressive episode she experienced during the last year of her life. The last volume of Queen Victoria's personal Journal was reviewed from a geriatrician's perspective, tracing the onset and course of depressive symptoms from entries beginning on 17 August 1900 and ending on 13 January 1901, 9 days before her death. The Queen's own words are supplemented with observations from contemporaneous secondary sources. The antecedents of Queen Victoria's late-life depression, including multiple losses, disabilities, and chronic pain, taken together with the presentation of vegetative, affective, and late cognitive symptoms, suggested the presence of a distinctively geriatric major depressive disorder. The absence of any other medical condition to explain the clinical picture seemed probable but not certain. Although historians and biographers have long been aware of Queen Victoria's final depression, the emphasis has mostly been on her earlier and prolonged mourning for her husband Prince Albert. Re-examined now, the Queen's Journal suggests that a severe late-life depressive episode occurring approximately in her last 5 months contributed meaningfully to her death.

Full Text Available Knowledge Management (KM is a collaborative and integrated approach adopted at various levels to ensure that an organization’s knowledge assets are best utilized to increase organizational performance. While KM has been adopted in a large number of sectors and organizations, colleges and universities, and the higher education sector in general, is yet to take full advantage of the possibilities offered by KM. Also, while past research has sought to highlight the importance of implementing KM in higher education, there is a lack of a single, clear template for KM implementation that universities leaders and administrators can adopt. The contribution of the paper is a practical, actionable, step-by-step plan, as well as a diagrammatic, theoretical framework for initiating KM successfully in colleges and universities.

First demonstration of olfactory learning and long term memory in honey bee queens.

Science.gov (United States)

Gong, Zhiwen; Tan, Ken; Nieh, James C

2018-05-18

As the primary source of colony reproduction, social insect queens play a vital role. However, the cognitive abilities of queens are not well understood, although queen learning and memory are essential in multiple species such as honey bees, in which virgin queens must leave the nest and then successful learn to navigate back over repeated nuptial flights. Honey bee queen learning has never been previously demonstrated. We therefore tested olfactory learning in queens and workers and examined the role of DNA methylation, which plays a key role in long term memory formation. We provide the first evidence that honey bee queens have excellent learning and memory. The proportion of honey bee queens that exhibited learning was 5-fold higher than workers at every tested age and, for memory, 4-fold higher than workers at a very young age. DNA methylation may play a key role in this queen memory because queens exhibiting remote memory had a more consistent elevation in Dnmt3 gene expression as compared to workers. Both castes also showed excellent remote memory (7 day memory), which was reduced by 14-20% by the DNA methylation inhibitor, zebularine. Given that queens live about 10-fold longer than workers, these results suggest that queens can serve as an excellently long-term reservoir of colony memory. © 2018.

Asymmetric dispersal and colonization success of Amazonian plant-ants queens.

Directory of Open Access Journals (Sweden)

Emilio M Bruna

Full Text Available The dispersal ability of queens is central to understanding ant life-history evolution, and plays a fundamental role in ant population and community dynamics, the maintenance of genetic diversity, and the spread of invasive ants. In tropical ecosystems, species from over 40 genera of ants establish colonies in the stems, hollow thorns, or leaf pouches of specialized plants. However, little is known about the relative dispersal ability of queens competing for access to the same host plants.We used empirical data and inverse modeling--a technique developed by plant ecologists to model seed dispersal--to quantify and compare the dispersal kernels of queens from three Amazonian ant species that compete for access to host-plants. We found that the modal colonization distance of queens varied 8-fold, with the generalist ant species (Crematogaster laevis having a greater modal distance than two specialists (Pheidole minutula, Azteca sp. that use the same host-plants. However, our results also suggest that queens of Azteca sp. have maximal distances that are four-sixteen times greater than those of its competitors.We found large differences between ant species in both the modal and maximal distance ant queens disperse to find vacant seedlings used to found new colonies. These differences could result from interspecific differences in queen body size, and hence wing musculature, or because queens differ in their ability to identify potential host plants while in flight. Our results provide support for one of the necessary conditions underlying several of the hypothesized mechanisms promoting coexistence in tropical plant-ants. They also suggest that for some ant species limited dispersal capability could pose a significant barrier to the rescue of populations in isolated forest fragments. Finally, we demonstrate that inverse models parameterized with field data are an excellent means of quantifying the dispersal of ant queens.

Gender-bias primes elicit queen-bee responses among senior policewomen.

Science.gov (United States)

Derks, Belle; Van Laar, Colette; Ellemers, Naomi; de Groot, Kim

2011-10-01

Queen bees are senior women in male-dominated organizations who have achieved success by emphasizing how they differ from other women. Although the behavior of queen bees tends to be seen as contributing to gender disparities in career outcomes, we argue that queen-bee behavior is actually a result of the gender bias and social identity threat that produce gender disparities in career outcomes. In the experiment reported here, we asked separate groups of senior policewomen to recall the presence or absence of gender bias during their careers, and we measured queen-bee responses (i.e., masculine self-descriptions, in-group distancing, and denying of discrimination). Such gender-bias priming increased queen-bee responses among policewomen with low gender identification, but policewomen with high gender identification responded with increased motivation to improve opportunities for other women. These results suggest that gender-biased work environments shape women's behavior by stimulating women with low gender identification to dissociate with other women and to display queen-bee responses as a way to achieve individual mobility.

Cellular energy metabolism maintains young status in old queen honey bees (Apis mellifera).

2018-05-02

Trophocytes and oenocytes of queen honey bees are used in studies of cellular longevity, but their cellular energy metabolism with age is poorly understood. In this study, the molecules involved in cellular energy metabolism were evaluated in the trophocytes and oenocytes of young and old queen bees. The findings indicated that there were no significant differences between young and old queen bees in β-oxidation, glycolysis, and protein synthesis. These results indicate that the cellular energy metabolism of trophocytes and oenocytes in old queen bees is similar to young queen bees and suggests that maintaining cellular energy metabolism in a young status may be associated with the longevity of queen bees. Fat and glycogen accumulation increased with age indicating that old queen bees are older than young queen bees. © 2018 Wiley Periodicals, Inc.

Do sexist organizational cultures create the Queen Bee?

Science.gov (United States)

Derks, Belle; Ellemers, Naomi; van Laar, Colette; de Groot, Kim

2011-09-01

'Queen Bees' are senior women in masculine organizational cultures who have fulfilled their career aspirations by dissociating themselves from their gender while simultaneously contributing to the gender stereotyping of other women. It is often assumed that this phenomenon contributes to gender discrimination in organizations, and is inherent to the personalities of successful career women. We argue for a social identity explanation and examine organizational conditions that foster the Queen Bee phenomenon. Participants were 94 women holding senior positions in diverse companies in The Netherlands who participated in an on-line survey. In line with predictions, indicators of the Queen Bee phenomenon (increased gender stereotyping and masculine self-descriptions) were found mostly among women who indicated they had started their career with low gender identification and who had subsequently experienced a high degree of gender discrimination on their way up. By contrast, the experience of gender discrimination was unrelated to signs of the Queen Bee phenomenon among women who indicated to be highly identified when they started their career. Results are discussed in light of social identity theory, interpreting the Queen Bee phenomenon as an individual mobility response of low gender identified women to the gender discrimination they encounter in their work. ©2010 The British Psychological Society.

Factors influencing survival duration and choice of virgin queens in the stingless bee Melipona quadrifasciata

Science.gov (United States)

Kärcher, Martin H.; Menezes, Cristiano; Alves, Denise A.; Beveridge, Oliver S.; Imperatriz-Fonseca, Vera-Lucia; Ratnieks, Francis L. W.

2013-06-01

In Melipona quadrifasciata, about 10 % of the females develop into queens, almost all of which are killed. Occasionally, a new queen replaces or supersedes the mother queen or heads a new colony. We investigated virgin queen fate in queenright and queenless colonies to determine the effects of queen behaviour, body mass, nestmate or non-nestmate status, queenright or queenless colony status, and, when queenless, the effect of the time a colony had been queenless, on survival duration and acceptance. None of 220 virgin queens observed in four observation hives ever attacked another virgin queen nor did any of 88 virgin queens introduced into queenright colonies ever attack the resident queen. A new queen was only accepted in a queenless colony. Factors increasing survival duration and acceptance of virgin queens were to emerge from its cell at 2 h of queenlessness, to hide, and to avoid fights with workers. In this way, a virgin queen was more likely to be available when a colony chooses a new queen, 24-48 h after resident queen removal. Running, walking or resting, antennating or trophallaxis, played little or no role, as did the factors body mass or nestmate. "Queen choice" took about 2 h during which time other virgin queens were still being killed by workers. During this agitated process, the bees congregated around the new queen. She inflated her abdomen and some of the workers deposited a substance on internal nest surfaces including the glass lid of the observation hive.

How biological systems resolve internal conflicts is a major evolutionary question. Social insect workers cooperate but also pursue individual interests, such as laying male eggs. The rewards of this individual selfishness can be reduced by policing, such as by killing worker-laid eggs. However, selfish individuals may evade policing. What factors prevent individuals from being able to evade policing? In the ant Pachycondyla inversa, workers kill (police) worker-laid eggs. Because the colony keeps eggs in piles and worker-laid and queen-laid eggs are chemically distinct, worker-laid eggs might become more acceptable once placed in the egg pile by odour transfer from touching queen-laid eggs. Here, we show that such “cue scrambling” does not occur. Worker-laid eggs that were sandwiched between three queen-laid eggs for 45 min were not more acceptable in a policing bioassay than control worker-laid eggs. Chemical analyses also showed that the surface hydrocarbon profile of these eggs was unchanged. Policing, therefore, is stable against this potential cheating mechanism probably because queen-laid eggs are made chemically distinct using chemicals, that are not easily transferred by physical contact.

Full Text Available Based on the standard requirements for a university, the Sorsogon State College has to produce graduates who manifest the training experts who will be involved in the professional practice and discovery of new knowledge. CHED Memorandum 46, series 2012 defines quality as the alignment and consistency of the learning environment with the institution’s vision, mission, and goals demonstrated by exceptional learning and service outcomes and the development of a culture of quality. This descriptive method of study utilized documentary analysis, unstructured interview, and focus group discussions (FGD which determined the status of the curricular program offerings of the College and assessed its readiness in terms of faculty complement, physical plant and facilities, and learning resources. SSC offers various curricular programs in its four campuses with their own concentration (Sorsogon City Campus concentration is in education, technology and engineering courses, Bulan campus in Business and IT courses, Magallanes campus in fisheries, and Castilla Campus in agriculture courses. Majority of the faculty members of the College are master’s degree holder with permanent status, few are holder of doctoral degree not enough to comply CHED typology standards. The learning resources of the College are enough to meet the needs of the students. The Sorsogon City Campus has the most density of population having the smallest land area among the four campuses. Other programs in the main campus have insufficient classrooms and some laboratory facilities are shared by the three departments including the graduate school program. In other campuses, their facilities have to be modernized and updated. The proposed strategic plan may be further reviewed and considered in the development plan of the College on becoming a university.

This paper describes design, fabrication and erection of Queen Mall Bridge, which is a new landmark in Minato-Mirai Yokohama. This bridge is two-span continuous cable stayed pedestrian bridge with a roof, and has a length 72.2 m, a width 18 m and a weight about 1,050 t. This bridge connects between the Queen`s Square and the second floor of Pacifico Yokohama. Achieving harmonious impression of the newly designed bridge in this area, glass roof was employed and all-weld method was applied to the in-site jointing of main girders and main tower in addition to the essential structural design. Since all-weld method was applied to the in-site jointing, highly accurate fabrication was considered during the in-site jointing. Due to the heavy traffic of the road below the bridge, the erection time was shortened under the severe erection conditions at night by large block method. Especially, accuracy control was considered for the whole shape management. Pre-assemble of all members was conducted just near the erection site, only 500 m away from the site, to shorten the construction time. 1 ref., 5 figs.

Selection against aerial dispersal in ants: two non-flying queen phenotypes in Pogonomyrmex laticeps.

Directory of Open Access Journals (Sweden)

Christian Peeters

Full Text Available The South American seed-harvester ant Pogonomyrmex laticeps has dimorphic queens: ergatoid (permanently wingless and brachypterous (short, non-functional wings. Surveys in western Argentina indicated that colonies near Chilecito, La Rioja Province, produced only ergatoid queens, while those near Punta Balasto, Catamarca Province (263 km away, produced only brachypterous queens. Brachypterous queens were significantly larger than ergatoid queens for 10 of 11 external characters, but both phenotypes had comparable reproductive potential, i.e., a spermatheca and a similar number of ovarioles. Using normal winged queens of the closely related P. uruguayensis for comparison, we determined that both queen phenotypes in P. laticeps had a full set of dorsal thoracic sclerites, albeit each sclerite was much reduced, whereas workers had a thorax without distinct dorsal sclerites. Sclerites were fused and immobile in ergatoid queens, while they were separable and fully articulated in brachypterous queens. Both phenotypes lacked the big indirect flight muscles, but brachypterous queens retained the tiny direct flight muscles. Overall, this dimorphism across populations indicates that there are alternative solutions to selective pressures against flying queens. We lack field data about colony founding strategy (independent or dependent for either queen phenotype, but colonies at both sites produced numerous gynes, and we infer that all foundresses initiate colonies independently and are obligate foragers.

Unequal subfamily proportions among honey bee queen and worker brood

Science.gov (United States)

Tilley; Oldroyd

1997-12-01

Queens from three colonies of feral honey bees, Apis mellifera were removed and placed in separate nucleus colonies. For each colony, eggs and larvae were taken from the nucleus and placed in the main hive on each of 3-4 consecutive weeks. Workers in the queenless parts selected young larvae to rear as queens. Queen pupae, together with the surrounding worker pupae, were removed from each colony and analysed at two to three microsatellite loci to determine their paternity. In all three colonies, the paternity of larvae chosen by the bees to rear as queens was not a random sample of the paternities in the worker brood, with certain subfamilies being over-represented in queens. These results support an important prediction of kin selection theory: when colonies are queenless, unequal relatedness within colonies could lead to the evolution of reproductive competition, that is some subfamilies achieving greater reproductive success than others. The mechanism by which such dominance is achieved could be through a system of kin recognition and nepotism, but we conclude that genetically based differential attractiveness of larvae for rearing as queens is more likely.Copyright 1997 The Association for the Study of Animal BehaviourCopyright 1997The Association for the Study of Animal Behaviour.

How many gamergates is an ant queen worth?

Science.gov (United States)

Monnin, Thibaud; Peeters, Christian

2008-02-01

Ant reproductives exhibit different morphological adaptations linked to dispersal and fertility. By reviewing the literature on taxa where workers can reproduce sexually (i.e. become gamergates) we show that (1) species with a single gamergate generally have lost the winged queen caste, whereas only half of the species with several gamergates have, and (2) single-gamergate species have smaller colonies than multiple-gamergate species. Comparison with “classical” ants without gamergates, where having one vs having several winged queens are two distinct syndromes, suggests that having one vs having several gamergates are not. Gamergate number does not affect the success of colony fission, but retention of the queen caste permits the option of independent foundation.

The Way to Cultivate Characteristic Talents Majoring in Marketing in Agricultural Universities and Colleges

Institute of Scientific and Technical Information of China (English)

QI Li

2012-01-01

In face of modern enterprises’ picky needs for marketing talents, the majority of graduates majoring in marketing from agricultural universities and colleges are often criticized due to old marketing concept, mediocre expertise, lack of practical ability and lack of communication skills in the process of searching job. It exposes the flaws of agricultural universities and colleges in training objectives of marketing talents, curriculum setting, features, teachers and their quality. The marketing education should serve the marketing practice needs, and the training mode and training way of marketing talents in agricultural universities and colleges need to be urgently reformed and improved. To satisfy the needs of enterprises, it is necessary to establish modern educational thought of marketing and training philosophy of application-based marketing talents; position the majors to highlight the characteristics of agricultural universities and colleges, cultivate all-around, application-based, inter-disciplinary marketing talents and explore new ways to cultivate agricultural marketing talents.

Medeiros, Sheila de Oliveira; Martins, Angelica Nascimento; Dias, Carlos Gabriel Almeida; Tanuri, Amilcar; Brindeiro, Rodrigo de Moraes

2012-05-25

Feline immunodeficiency virus (FIV) is a naturally occurring lentivirus that infects cats. The primary mode of transmission occurs through bite wounds, and other routes are difficult to observe in nature. The purpose of this study was to evaluate FIV transmission from queen to kitten in a colony of naturally infected stray cats. With this aim, a queen was monitored over a period of three years. A blood sample was taken to amplify and sequence gag, pol and env regions of the virus from the queen, two kittens and other cats from the colony. Phylogenetic analysis showed evidence of queen to kitten transmission.

Review of samples of sediment, tailings, and waters adjacent to the Cactus Queen gold mine, Kern County, California

The Cactus Queen Mine is located in the western Mojave Desert in Kern County, California. The Cactus Queen gold-silver (Au-Ag) deposit is similar to other Au-Ag deposits hosted in Miocene volcanic rocks that consist of silicic domes and associated flows, pyroclastic rocks, and subvolcanic intrusions. The volcanic rocks were emplaced onto a basement of Mesozoic silicic intrusive rocks. A part of the Cactus Queen Mine is located on Federal land managed by the U.S. Bureau of Land Management (BLM). Staff from the BLM initially sampled the mine area and documented elevated concentrations of arsenic (As) in tailings and sediment. BLM then requested that the U.S. Geological Survey (USGS), in collaboration with Chapman University, measure and characterize As and other geochemical constituents in sediment, tailings, and waters on the part of the mine on Federal lands. This report is made in response to the request by the BLM, the lead agency mandated to conduct a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - Removal Site Investigation (RSI). The RSI applies to the potential removal of As-contaminated mine waste from the Cactus Queen Mine as a means of reducing As release and exposure to humans and biota. This report summarizes data obtained from field sampling of sediments, mine tailings, and surface waters at the Cactus Queen Mine on January 27, 2008. Our results provide a preliminary assessment of the sources of As and associated chemical constituents that could potentially impact humans and biota.

Gajger, Ivana Tlak; Sakač, Martina; Gregorc, Aleš

2017-09-01

High honey bee losses around the world have been linked in part by the regular use of neonicotinoids in agriculture. In light of the current situation, the aim of this study was to investigate the effects of thiamethoxam on the development of the reproductive system and physiology in the honey bee queen. Two experimental groups of honey bee queen larvae were treated with thiamethoxam during artificial rearing, applied via artificial feed in two cycles. In the first rearing cycle, honey bee larvae received a single treatment dose (4.28 ng thiamethoxam/queen larva on the 4th day after larvae grafting in artificial queen cells), while the second honey bee queen rearing cycle received a double treatment dose (total of 8.56 ng thiamethoxam/queen larva on the 4th and 5th day after larvae grafting in artificial queen cells). After emerging, queens were anesthetized and weighed, and after mating with drones were anesthetized, weighed, and sectioned. Ovary mass and number of stored sperm were determined. Body weight differed between untreated and treated honey bee queens. The results also show a decrease in the number of sperm within honey bee queen spermathecae that received the double thiamethoxam dose.

Full Text Available The three roles of a higher education institution are teaching, research and community service. The objective of the article is to analyse how a university regional college can implement the task of community service via its curriculum development. The theoretical base lies on the positions of internationally recognised scientists of education policy as well as OECD definitions and clarifications that are compared to the cases of the regional colleges (in Narva and Kuressaare of two universities (respectively University of Tartu and Tallinn University of Technology. The set task enables to study as a whole such components as the content and design of curricula, teaching and assessment methods, extracurricular activities, topics and supervision of students’ research works, cooperation with partners. A comprehensive approach is a precondition of a well-functioning curriculum, with community service being the unifying aspect. The results of current study are applicable in case of the analysed curricula and colleges, they partly applicable in case of any other similar curricula and units. Prerequisites of the colleges' network evolvement, holistic impact and compliance with the region-specific needs is a significant topic the additional study of which has already begun.

Chemical Characterization of Young Virgin Queens and Mated Egg-Laying Queens in the Ant Cataglyphis cursor: Random Forest Classification Analysis for Multivariate Datasets.

2018-02-01

Social insects are well known for their extremely rich chemical communication, yet their sex pheromones remain poorly studied. In the thermophilic and thelytokous ant, Cataglyphis cursor, we analyzed the cuticular hydrocarbon profiles and Dufour's gland contents of queens of different age and reproductive status (sexually immature gynes, sexually mature gynes, mated and egg-laying queens) and of workers. Random forest classification analyses showed that the four groups of individuals were well separated for both chemical sources, except mature gynes that clustered with queens for cuticular hydrocarbons and with immature gynes for Dufour's gland secretions. Analyses carried out with two groups of females only allowed identification of candidate chemicals for queen signal and for sexual attractant. In particular, gynes produced more undecane in the Dufour's gland. This chemical is both the sex pheromone and the alarm pheromone of the ant Formica lugubris. It may therefore act as sex pheromone in C. cursor, and/or be involved in the restoration of monogyny that occurs rapidly following colony fission. Indeed, new colonies often start with several gynes and all but one are rapidly culled by workers, and this process likely involves chemical signals between gynes and workers. These findings open novel opportunities for experimental studies of inclusive mate choice and queen choice in C. cursor.

Social regulation of maternal traits in nest-founding bumble bee (Bombus terrestris) queens.

Science.gov (United States)

Woodard, S Hollis; Bloch, Guy; Band, Mark R; Robinson, Gene E

2013-09-15

During the nest-founding phase of the bumble bee colony cycle, queens undergo striking changes in maternal care behavior. Early in the founding phase, prior to the emergence of workers in the nest, queens are reproductive and also provision and feed their offspring. However, later in the founding phase, queens reduce their feeding of larvae and become specialized on reproduction. This transition is synchronized with the emergence of workers in the colony, who assume the task of feeding their siblings. Using a social manipulation experiment with the bumble bee Bombus terrestris, we tested the hypothesis that workers regulate the transition from feeding brood to specialization on reproduction in nest-founding bumble bee queens. Consistent with this hypothesis, we found that early-stage nest-founding queens with workers prematurely added to their nests reduce their brood-feeding behavior and increase egg laying, and likewise, late-stage nest-founding queens increase their brood-feeding behavior and decrease egg-laying when workers are removed from their nests. Further, brood-feeding and egg-laying behaviors were negatively correlated. We used Agilent microarrays designed from B. terrestris brain expressed sequenced tags (ESTs) to explore a second hypothesis, that workers alter brain gene expression in nest-founding queens. We found evidence that brain gene expression in nest-founding queens is altered by the presence of workers, with the effect being much stronger in late-stage founding queens. This study provides new insights into how the transition from feeding brood to specialization on reproduction in queen bumble bees is regulated during the nest initiation phase of the colony cycle.

Gregorc Aleš

2015-12-01

Full Text Available In this three-year-trial study, we examined the quality of mated queens based on morphological and physiology traits. At each location, sister queen bees were reared each year from one Apis mellifera carnica breeder queen. Queens were also reared and mated in different locations. Altogether, we sampled and analysed 324 queens from 27 apiaries in 2006, 288 queens from 24 apiaries in 2008, and 276 queens from 23 apiaries in 2010. Nine queens from each apiary were sampled and dissected for morphological analyses and Nosema ceranae (N. ceranae spores, if present, were quantified. Three queens from each apiary were prepared and tested for four viruses: acute bee paralysis virus (ABPV, black queen cell virus (BQCV, deformed wing virus (DWV, and sacbrood virus (SBV. The highest average queen weight of 209.49 ± 9.82 mg was detected in 2008. The highest average ovary weight of 78.67 ± 11.86 mg was detected in 2010, and the highest number of ovarioles was 161.59 ± 8.70 in 2006. The average number of spermatozoa in queens ranged from 3.30 x 106 in 2006 to 5.23 x 106 in 2010. Nosema ceranae spores were found in queens sampled in 2008 and 2010. Viruses were discovered sporadically during the queen testing periods from 2006 - 2010. This study importantly demonstrates that queens from rearing stations require regular evaluation for morphological and physiological changes as well as for infection from harmful pathogens. These results could also be used in establishing relevant commercial standards for rearing quality queens.

Queen pheromones: The chemical crown governing insect social life

DEFF Research Database (Denmark)

Holman, Luke

2010-01-01

Group-living species produce signals that alter the behavior and even the physiology of their social partners. Social insects possess especially sophisticated chemical communication systems that govern every aspect of colony life, including the defining feature of eusociality: reproductive division...... of labor. Current evidence hints at the central importance of queen pheromones, but progress has been hindered by the fact that such pheromones have only been isolated in honeybees. In a pair of papers on the ant Lasius niger, we identified and investigated a queen pheromone regulating worker sterility...... with other studies, these results indicate that queen pheromones are honest signals of quality that simultaneously regulate multiple social behaviors....

Social context predicts recognition systems in ant queens

DEFF Research Database (Denmark)

Dreier, Stéphanie Agnès Jeanine; d'Ettorre, Patrizia

2009-01-01

Recognition of group-members is a key feature of sociality. Ants use chemical communication to discriminate nestmates from intruders, enhancing kin cooperation and preventing parasitism. The recognition code is embedded in their cuticular chemical profile, which typically varies between colonies....... We predicted that ants might be capable of accurate recognition in unusual situations when few individuals interact repeatedly, as new colonies started by two to three queens. Individual recognition would be favoured by selection when queens establish dominance hierarchies, because repeated fights...... for dominance are costly; but it would not evolve in absence of hierarchies. We previously showed that Pachycondyla co-founding queens, which form dominance hierarchies, have accurate individual recognition based on chemical cues. Here, we used the ant Lasius niger to test the null hypothesis that individual...

Eco-evolutionary Red Queen dynamics regulate biodiversity in a metabolite-driven microbial system.

Science.gov (United States)

Bonachela, Juan A; Wortel, Meike T; Stenseth, Nils Chr

2017-12-15

The Red Queen Hypothesis proposes that perpetual co-evolution among organisms can result from purely biotic drivers. After more than four decades, there is no satisfactory understanding as to which mechanisms trigger Red Queen dynamics or their implications for ecosystem features such as biodiversity. One reason for such a knowledge gap is that typical models are complicated theories where limit cycles represent an idealized Red Queen, and therefore cannot be used to devise experimental setups. Here, we bridge this gap by introducing a simple model for microbial systems able to show Red Queen dynamics. We explore diverse biotic sources that can drive the emergence of the Red Queen and that have the potential to be found in nature or to be replicated in the laboratory. Our model enables an analytical understanding of how Red Queen dynamics emerge in our setup, and the translation of model terms and phenomenology into general underlying mechanisms. We observe, for example, that in our system the Red Queen offers opportunities for the increase of biodiversity by facilitating challenging conditions for intraspecific dominance, whereas stasis tends to homogenize the system. Our results can be used to design and engineer experimental microbial systems showing Red Queen dynamics.

The Red Queen lives: Epistasis between linked resistance loci.

Metzger, César M J A; Luijckx, Pepijn; Bento, Gilberto; Mariadassou, Mahendra; Ebert, Dieter

2016-02-01

A popular theory explaining the maintenance of genetic recombination (sex) is the Red Queen Theory. This theory revolves around the idea that time-lagged negative frequency-dependent selection by parasites favors rare host genotypes generated through recombination. Although the Red Queen has been studied for decades, one of its key assumptions has remained unsupported. The signature host-parasite specificity underlying the Red Queen, where infection depends on a match between host and parasite genotypes, relies on epistasis between linked resistance loci for which no empirical evidence exists. We performed 13 genetic crosses and tested over 7000 Daphnia magna genotypes for resistance to two strains of the bacterial pathogen Pasteuria ramosa. Results reveal the presence of strong epistasis between three closely linked resistance loci. One locus masks the expression of the other two, while these two interact to produce a single resistance phenotype. Changing a single allele on one of these interacting loci can reverse resistance against the tested parasites. Such a genetic mechanism is consistent with host and parasite specificity assumed by the Red Queen Theory. These results thus provide evidence for a fundamental assumption of this theory and provide a genetic basis for understanding the Red Queen dynamics in the Daphnia-Pasteuria system. © 2016 The Author(s).

Mating with stressed males increases the fitness of ant queens.

Directory of Open Access Journals (Sweden)

Alexandra Schrempf

Full Text Available BACKGROUND: According to sexual conflict theory, males can increase their own fitness by transferring substances during copulation that increase the short-term fecundity of their mating partners at the cost of the future life expectancy and re-mating capability of the latter. In contrast, sexual cooperation is expected in social insects. Mating indeed positively affects life span and fecundity of young queens of the male-polymorphic ant Cardiocondyla obscurior, even though males neither provide nuptial gifts nor any other care but leave their mates immediately after copulation and die shortly thereafter. PRINCIPAL FINDINGS: Here, we show that mating with winged disperser males has a significantly stronger impact on life span and reproductive success of young queens of C. obscurior than mating with wingless fighter males. CONCLUSIONS: Winged males are reared mostly under stressful environmental conditions, which force young queens to disperse and found their own societies independently. In contrast, queens that mate with wingless males under favourable conditions usually start reproducing in the safety of the established maternal nest. Our study suggests that males of C. obscurior have evolved mechanisms to posthumously assist young queens during colony founding under adverse ecological conditions.

2012-01-01

This study aimed to examine college student physical activity promotion. A cross-sectional approach to qualitative research was used. Southeastern state university system. Fourteen of 15 (93%) universities recruited were included in this study; 22 university employees participated in a semistructured interview. Nonprobabilistic purposive and snowball sampling strategies were used to recruit individuals who were likely to be engaged in physical activity promotion efforts on their respective campuses. Thematic analyses lead to the identification of emerging themes that were coded and analyzed using NVivo software. Themes informed three main areas: key personnel responsible for promoting physical activity to students, actual physical activity promotion efforts implemented, and factors that influence student physical activity promotion. Results suggest that ecological approaches to promote physical activity on college campuses are underused, the targeting of mediators of physical activity in college students is limited, and values held by university administration influence campus physical activity promotion. Findings support recommendations for future research and practice. Practitioners should attempt to implement social ecological approaches that target scientifically established mediators of physical activity in college students. Replication of this study is needed to compare these findings with other types of universities, and to investigate the relationship between promotion activities (type and exposure) and physical activity behaviors of college students.

Queen honeybees (Apis mellifera) have a much longer lifespan than worker bees. Whether cellular degradation activity is involved in the longevity of queen bees is unknown. In the present study, cellular degradation activity was evaluated in the trophocytes and oenocytes of young and old queen bees. The results indicated that (i) 20S proteasome activity and the size of autophagic vacuoles decreased with aging, and (ii) there were no significant differences between young and old queen bees with regard to 20S proteasome expression or efficiency, polyubiquitin aggregate expression, microtubule-associated protein 1 light chain 3-II (LC3-II) expression, 70 kDa heat shock cognate protein (Hsc70) expression, the density of autophagic vacuoles, p62/SQSTM1 expression, the activity or density of lysosomes, or molecular target of rapamycin expression. These results indicate that cellular degradation activity maintains a youthful status in the trophocytes and oenocytes of queen bees during aging and that cellular degradation activity is involved in maintaining the longevity of queen bees.

Individual Recognition in Ant Queens

Personal relationships are the cornerstone of vertebrate societies, but insect societies are either too large for individual recognition, or their members were assumed to lack the necessary cognitive abilities 1 and 2 . This paradigm has been challenged by the recent discovery that paper wasps...... recognize each other's unique facial color patterns [3] . Individual recognition is advantageous when dominance hierarchies control the partitioning of work and reproduction 2 and 4 . Here, we show that unrelated founding queens of the ant Pachycondyla villosa use chemical cues to recognize each other...... individually. Aggression was significantly lower in pairs of queens that had previously interacted than in pairs with similar social history but no experience with one another. Moreover, subordinates discriminated familiar and unfamiliar dominants in choice experiments in which physical contact, but not odor...

Although two-thirds of graduating high school seniors attend college or university in the U.S., there is a paucity of national or state specific research regarding SRH services available on or near college and university campuses. A review of websites for all colleges and universities in Georgia was conducted to evaluate sexual health services available on campuses and evidence of referral to community providers. Of 96 colleges in Georgia, 44░had campus-located health centers, with only 3 at two-year colleges. Overall SRH service provision was low, with great variation between colleges. Distances between colleges and Title X clinics ranged from 0.33 to 35.45 miles. Many students lack access to campus health centers, and information on college websites regarding SRH service availability and referrals differs dramatically between campuses. In the absence of robust campus-located services, schools should highlight where students can obtain comprehensive SRH care in the community.

Queens and Workers Contribute Differently to Adaptive Evolution in Bumble Bees and Honey Bees.

Eusociality represents a major transition in evolution and is typified by cooperative brood care and reproductive division of labor between generations. In bees, this division of labor allows queens and workers to phenotypically specialize. Worker traits associated with helping are thought to be crucial to the fitness of a eusocial lineage, and recent studies of honey bees (genus Apis) have found that adaptively evolving genes often have worker-biased expression patterns. It is unclear however if worker-biased genes are disproportionately acted on by strong positive selection in all eusocial insects. We undertook a comparative population genomics study of bumble bees (Bombus) and honey bees to quantify natural selection on queen- and worker-biased genes across two levels of social complexity. Despite sharing a common eusocial ancestor, genes, and gene groups with the highest levels of positive selection were often unique within each genus, indicating that life history and the environment, but not sociality per se, drives patterns of adaptive molecular evolution. We uncovered differences in the contribution of queen- and worker-biased genes to adaptive evolution in bumble bees versus honey bees. Unlike honey bees, where worker-biased genes are enriched for signs of adaptive evolution, genes experiencing positive selection in bumble bees were predominately expressed by reproductive foundresses during the initial solitary-founding stage of colonies. Our study suggests that solitary founding is a major selective pressure and that the loss of queen totipotency may cause a change in the architecture of selective pressures upon the social insect genome. © The Author 2017.

Sexual Cooperation: Mating Increases Longevity in Ant Queens

DEFF Research Database (Denmark)

Schrempf, Alexandra; Heinze, Jürgen; Cremer, Sylvia

Divergent reproductive interests of males and females often cause sexual conflict [1] and [2] . Males of many species manipulate females by transferring seminal fluids that boost female short-term fecundity while decreasing their life expectancy and future reproductivity [3] and [4] . The life...... history of ants, however, is expected to reduce sexual conflict; whereas most insect females show repeated phases of mating and reproduction, ant queens mate only during a short period early in life and undergo a lifelong commitment to their mates by storing sperm [5] .

Today, the websites of college and university libraries play an important role in providing the necessary services for clients. These websites not only allow the users to access different collections of library resources, but also provide them with the necessary guidance in order to use the information. The goal of this study is the quality evaluation of the college library websites in Iranian Medical Universities based on the Stover model. This study uses an analytical survey method and is an applied study. The data gathering tool is the standard checklist provided by Stover, which was modified by the researchers for this study. The statistical population is the college library websites of the Iranian Medical Universities (146 websites) and census method was used for investigation. The data gathering method was a direct access to each website and filling of the checklist was based on the researchers' observations. Descriptive and analytical statistics (Analysis of Variance (ANOVA)) were used for data analysis with the help of the SPSS software. The findings showed that in the dimension of the quality of contents, the highest average belonged to type one universities (46.2%) and the lowest average belonged to type three universities (24.8%). In the search and research capabilities, the highest average belonged to type one universities (48.2%) and the lowest average belonged to type three universities. In the dimension of facilities provided for the users, type one universities again had the highest average (37.2%), while type three universities had the lowest average (15%). In general the library websites of type one universities had the highest quality (44.2%), while type three universities had the lowest quality (21.1%). Also the library websites of the College of Rehabilitation and the College of Paramedics, of the Shiraz University of Medical Science, had the highest quality scores. The results showed that there was a meaningful difference between the quality

Long-Lived Termite Queens Exhibit High Cu/Zn-Superoxide Dismutase Activity

Directory of Open Access Journals (Sweden)

Eisuke Tasaki

2018-01-01

Full Text Available In most organisms, superoxide dismutases (SODs are among the most effective antioxidant enzymes that regulate the reactive oxygen species (ROS generated by oxidative energy metabolism. ROS are considered main proximate causes of aging. However, it remains unclear if SOD activities are associated with organismal longevity. The queens of eusocial insects, such as termites, ants, and honeybees, exhibit extraordinary longevity in comparison with the nonreproductive castes, such as workers. Therefore, the queens are promising candidates to study the underlying mechanisms of aging. Here, we found that queens have higher Cu/Zn-SOD activity than nonreproductive individuals of the termite Reticulitermes speratus. We identified three Cu/Zn-SOD sequences and one Mn-SOD sequence by RNA sequencing in R. speratus. Although the queens showed higher Cu/Zn-SOD activity than the nonreproductive individuals, there were no differences in their expression levels of the Cu/Zn-SOD genes RsSOD1 and RsSOD3A. Copper (Cu2+ and Cu+ is an essential cofactor for Cu/Zn-SOD enzyme activity, and the queens had higher concentrations of copper than the workers. These results suggest that the high Cu/Zn-SOD activity of termite queens is related to their high levels of the cofactor rather than gene expression. This study highlights that Cu/Zn-SOD activity contributes to extraordinary longevity in termites.

Full Text Available We evaluated varroa infestation and the performance of Africanized honeybee colonies with queens selected for honey and royal jelly production, and also unselected queens, correlating with climatic variables. In Campo Alegre, Santa Catarina State, Brazil, the experiment I used 10 Langstroth hives and in Mafra, Santa Catarina State, Brazil, the experiment II was performed with 15 Schenk hives. A mapping in areas of sealed and unsealed brood, honey and pollen was carried out on days zero, 45 and 90 days after the introduction of the queen. In the experiment I, there was interaction between the type of queen selection and the evaluation period for areas of sealed brood, honey, and total stored food. The group selected for royal jelly production presented larger sealed brood area and smaller honey area at 90 days. Varroa infestation was lower (p < 0.05 at 90 days. The type of queen selection and the evaluation period influenced the sealed brood area, the total brood and the total area occupied in the colony. The high relative humidity caused greater honey storage for the local group. The different groups of queens presented different behavior according to the environment in which they are settled.

2010-08-01

Thelytokous parthenogenesis in which diploid females are produced from unfertilized eggs, was recently reported for some ant species. Here, we document thelytokous reproduction by queens in the polygynous species Pyramica membranifera. Queens that emerged in the laboratory were kept with or without workers under laboratory conditions. Independent colony founding was successful for a few queens if prey was provided. All artificial colonies, which started with a newly emerged queen and workers produced new workers and some of the colonies also produced female sexuals. Some of the female sexuals shed their wings in the laboratory and started formation of new polygynous colonies. Workers had no ovaries and thus, were obligatorily sterile.

The Effects of Pesticides on Queen Rearing and Virus Titers in Honey Bees (Apis mellifera L.)

Science.gov (United States)

DeGrandi-Hoffman, Gloria; Chen, Yanping; Simonds, Roger

2013-01-01

The effects of sublethal pesticide exposure on queen emergence and virus titers were examined. Queen rearing colonies were fed pollen with chlorpyrifos (CPF) alone (pollen-1) and with CPF and the fungicide Pristine® (pollen-2). Fewer queens emerged when larvae from open foraging (i.e., outside) colonies were reared in colonies fed pollen-1 or 2 compared with when those larvae were reared in outside colonies. Larvae grafted from and reared in colonies fed pollen-2 had lower rates of queen emergence than pollen-1 or outside colonies. Deformed wing virus (DWV) and black queen cell virus were found in nurse bees from colonies fed pollen-1 or 2 and in outside colonies. The viruses also were detected in queen larvae. However, we did not detect virus in emerged queens grafted from and reared in outside colonies. In contrast, DWV was found in all emerged queens grafted from colonies fed pollen-1 or 2 either reared in outside hives or those fed pollen-1 or 2. The results suggest that sublethal exposure of CPF alone but especially when Pristine® is added reduces queen emergence possibly due to compromised immunity in developing queens. PMID:26466796

Dominance and queen succession in captive colonies of the eusocial naked mole-rat, Heterocephalus glaber.

Science.gov (United States)

Clarke, F M; Faulkes, C G

1997-07-22

Naked mole-rat colonies exhibit a high reproductive skew, breeding being typically restricted to one female (the 'queen') and one to three males. Other colony members are reproductively suppressed, although this suppression can be reversed following the removal or death of the queen. We examined dominance and queen succession within captive colonies to investigate the relationship between urinary testosterone and cortisol, dominance rank and reproductive status; and to determine if behavioural and/or physiological parameters can be used as predictors of queen succession. Social structure was characterized by a linear dominance hierarchy before and after queen removal. Prior to queen removal, dominance rank was negatively correlated with body weight and urinary testosterone and cortisol titres in males and females. Queen removal results in social instability and aggression between high ranking individuals. Dominance rank appears to be a good predictor of reproductive status: queens are the highest ranking colony females and are succeeded by the next highest ranking females. The intense dominance-related aggression that accompanies reproductive succession in naked mole-rats provides empirical support for optimal skew theory.

Experiments are reported on learning in virgin Africanized honey bee queens (Apis mellifera L.). Queens restrained in a "Pavlovian harness" received a pairing of hexanal odor with a 1.8-M feeding of sucrose solution. Compared to explicitly unpaired controls, acquisition was rapid in reaching about 90%. Acquisition was also rapid in queens receiving an unconditioned stimulus of "bee candy" or an unconditioned stimulus administered by worker bees. During extinction the conditioned response declines. The steepest decline was observed in queens receiving an unconditioned stimulus of bee candy. These findings extend previous work on learning of Afrianized honey bee workers to a population of queen bees.

Genetic reincarnation of workers as queens in the Eastern honeybee Apis cerana.

Science.gov (United States)

Holmes, M J; Tan, K; Wang, Z; Oldroyd, B P; Beekman, M

2015-01-01

Thelytokous parthenogenesis, or the asexual production of female offspring, is rare in the animal kingdom, but relatively common in social Hymenoptera. However, in honeybees, it is only known to be ubiquitous in one subspecies of Apis mellifera, the Cape honeybee, A. mellifera capensis. Here we report the appearance of queen cells in two colonies of the Eastern honeybee Apis cerana that no longer contained a queen or queen-produced brood to rear queens from. A combination of microsatellite genotyping and the timing of the appearance of these individuals excluded the possibility that they had been laid by the original queen. Based on the genotypes of these individuals, thelytokous production by natal workers is the most parsimonious explanation for their existence. Thus, we present the first example of thelytoky in a honeybee outside A. mellifera. We discuss the evolutionary and ecological consequences of thelytoky in A. cerana, in particular the role thelytoky may play in the recent invasions by populations of this species.

2014-08-01

The Kilimanjaro Christian Medical University (KCMU) College and the Medical Education Partnership Initiative (MEPI) are addressing the crisis in Tanzanian health care manpower by modernizing the college's medical education with new tools and techniques. With a $10 million MEPI grant and the participation of its partner, Duke University, KCMU is harnessing the power of information technology (IT) to upgrade tools for students and faculty. Initiatives in eLearning have included bringing fiber-optic connectivity to the campus, offering campus-wide wireless access, opening student and faculty computer laboratories, and providing computer tablets to all incoming medical students. Beyond IT, the college is also offering wet laboratory instruction for hands-on diagnostic skills, team-based learning, and clinical skills workshops. In addition, modern teaching tools and techniques address the challenges posed by increasing numbers of students. To provide incentives for instructors, a performance-based compensation plan and teaching awards have been established. Also for faculty, IT tools and training have been made available, and a medical education course management system is now being widely employed. Student and faculty responses have been favorable, and the rapid uptake of these interventions by students, faculty, and the college's administration suggests that the KCMU College MEPI approach has addressed unmet needs. This enabling environment has transformed the culture of learning and teaching at KCMU College, where a path to sustainability is now being pursued.

2007-01-01

Universities and colleges serve to be institutions of education excellence; however, problems in the areas of occupational safety may undermine such goals. Occupational safety must be the concern of every employee in the organization, regardless of job position. Safety climate surveys have been suggested as important tools for measuring the effectiveness and improvement direction of safety programs. Thus, this study aims to investigate the influence of organizational and individual factors on safety climate in university and college laboratories. Employees at 100 universities and colleges in Taiwan were mailed a self-administered questionnaire survey; the response rate was 78%. Multivariate analysis of variance revealed that organizational category of ownership, the presence of a safety manager and safety committee, gender, age, title, accident experience, and safety training significantly affected the climate. Among them, accident experience and safety training affected the climate with practical significance. The authors recommend that managers should address important factors affecting safety issues and then create a positive climate by enforcing continuous improvements.

2012-01-01

Objective We sought to describe the 2009–2010 seasonal influenza vaccine coverage of college students. Participants 4090 college students from eight North Carolina universities participated in a confidential, web-based survey in October-November 2009. Methods Associations between self-reported 2009–2010 seasonal influenza vaccination and demographic characteristics, campus activities, parental education, and email usage were assessed by bivariate analyses and by a mixed-effects model adjusting for clustering by university. Results Overall, 20% of students (range 14%–30% by university) reported receiving 2009–2010 seasonal influenza vaccine. Being a freshman, attending a private university, having a college-educated parent, and participating in academic clubs/honor societies predicted receipt of influenza vaccine in the mixed-effects model. Conclusions The self-reported 2009–2010 influenza vaccine coverage was one-quarter of the 2020 Healthy People goal (80%) for healthy persons 18–64 years of age. College campuses have the opportunity to enhance influenza vaccine coverage among its diverse student populations. PMID:23157195

Tolerating an infection: an indirect benefit of co-founding queen associations in the ant Lasius niger

Science.gov (United States)

Pull, Christopher D.; Hughes, William O. H.; Brown, Mark J. F.

2013-12-01

Pathogens exert a strong selection pressure on organisms to evolve effective immune defences. In addition to individual immunity, social organisms can act cooperatively to produce collective defences. In many ant species, queens have the option to found a colony alone or in groups with other, often unrelated, conspecifics. These associations are transient, usually lasting only as long as each queen benefits from the presence of others. In fact, once the first workers emerge, queens fight to the death for dominance. One potential advantage of co-founding may be that queens benefit from collective disease defences, such as mutual grooming, that act against common soil pathogens. We test this hypothesis by exposing single and co-founding queens to a fungal parasite, in order to assess whether queens in co-founding associations have improved survival. Surprisingly, co-foundresses exposed to the entomopathogenic fungus Metarhizium did not engage in cooperative disease defences, and consequently, we find no direct benefit of multiple queens on survival. However, an indirect benefit was observed, with parasite-exposed queens producing more brood when they co-founded, than when they were alone. We suggest this is due to a trade-off between reproduction and immunity. Additionally, we report an extraordinary ability of the queens to tolerate an infection for long periods after parasite exposure. Our study suggests that there are no social immunity benefits for co-founding ant queens, but that in parasite-rich environments, the presence of additional queens may nevertheless improve the chances of colony founding success.

The pipeline of physiology courses in community colleges: to university, medical school, and beyond.

Science.gov (United States)

McFarland, Jenny; Pape-Lindstrom, Pamela

2016-12-01

Community colleges are significant in the landscape of undergraduate STEM (science technology, engineering, and mathematics) education (9), including biology, premedical, and other preprofessional education. Thirty percent of first-year medical school students in 2012 attended a community college. Students attend at different times in high school, their first 2 yr of college, and postbaccalaureate. The community college pathway is particularly important for traditionally underrepresented groups. Premedical students who first attend community college are more likely to practice in underserved communities (2). For many students, community colleges have significant advantages over 4-yr institutions. Pragmatically, they are local, affordable, and flexible, which accommodates students' work and family commitments. Academically, community colleges offer teaching faculty, smaller class sizes, and accessible learning support systems. Community colleges are fertile ground for universities and medical schools to recruit diverse students and support faculty. Community college students and faculty face several challenges (6, 8). There are limited interactions between 2- and 4-yr institutions, and the ease of transfer processes varies. In addition, faculty who study and work to improve the physiology education experience often encounter obstacles. Here, we describe barriers and detail existing resources and opportunities useful in navigating challenges. We invite physiology educators from 2- and 4-yr institutions to engage in sharing resources and facilitating physiology education improvement across institutions. Given the need for STEM majors and health care professionals, 4-yr colleges and universities will continue to benefit from students who take introductory biology, physiology, and anatomy and physiology courses at community colleges.

Depression of brain dopamine and its metabolite after mating in European honeybee (Apis mellifera) queens

Science.gov (United States)

Harano, Ken-Ichi; Sasaki, Ken; Nagao, Takashi

2005-07-01

To explore neuro-endocrinal changes in the brain of European honeybee (Apis mellifera) queens before and after mating, we measured the amount of several biogenic amines, including dopamine and its metabolite in the brain of 6- and 12-day-old virgins and 12-day-old mated queens. Twelve-day-old mated queens showed significantly lower amounts of dopamine and its metabolite (N-acetyldopamine) than both 6- and 12-day-old virgin queens, whereas significant differences in the amounts of these amines were not detected between 6- and 12-day-old virgin queens. These results are explained by down-regulation of both synthesis and secretion of brain dopamine after mating. It is speculated that higher amounts of brain dopamine in virgin queens might be involved in activation of ovarian follicles arrested in previtellogenic stages, as well as regulation of their characteristic behaviors.

2012-01-04

To understand the olfactory mechanism of honeybee antennae in detecting specific volatile compounds in the atmosphere, antennal proteome differences of drone, worker and queen were compared using 2-DE, mass spectrometry and bioinformatics. Therefore, 107 proteins were altered their expressions in the antennae of drone, worker and queen bees. There were 54, 21 and 32 up-regulated proteins in the antennae of drone, worker and queen, respectively. Proteins upregulated in the drone antennae were involved in fatty acid metabolism, antioxidation, carbohydrate metabolism and energy production, protein folding and cytoskeleton. Proteins upregulated in the antennae of worker and queen bees were related to carbohydrate metabolism and energy production while molecular transporters were upregulated in the queen antennae. Our results explain the role played by the antennae of drone is to aid in perceiving the queen sexual pheromones, in the worker antennae to assist for food search and social communication and in the queen antennae to help pheromone communication with the worker and the drone during the mating flight. This first proteomic study significantly extends our understanding of honeybee olfactory activities and the possible mechanisms played by the antennae in response to various environmental, social, biological and biochemical signals.

The last drone’s endophallus (n = 29), if present, was removed from the mated queens for deformed wing virus quantification, leading to the detection of high-level infection in 3 endophalli. After...... oviposition, viral quantification revealed that seven of the 30 queens had high-level deformed wing virus infections, in all tissues, including the semen stored in the spermathecae. Two groups of either unmated queens (n = 8) with induced egg laying, or queens (n = 12) mated in isolation with drones showing...... comparatively low deformed wing virus infections served as control. None of the control queens exhibited high-level viral infections.

Sir James Reid and the Death of Queen Victoria: An Early Model for End-of-Life Care.

Science.gov (United States)

Abrams, Robert C

2015-12-01

An appraisal of the last ten days of Queen Victoria's life, viewed primarily from the perspective of her personal physician, Sir James Reid, is presented. Sir James' clinical encounters with his patient and the Royal Family are examined to reveal his strategic and medical thinking and gauge his level of success in basic palliative aims. It was found that the lack of effective medical interventions, tensions within the Royal Family, the importance of his post to Sir James' professional career, and the political ramifications unavoidably connected with the illness of a head of state, all presented challenges to Reid's efforts to ease the physical and emotional pain of Queen Victoria's dying. Key features of Sir James' approach included reliance on physician-patient and physician-family relationships, emphasis on emotional support for the patient, and the careful selection of interventions for the family. In the first years of the 20th century, an era when the contemporary concepts of palliative care, hospice, and family dynamics did not exist, Sir James' management of the Queen's final illness suggested an early model for end-of-life care. By the end of Queen Victoria's life, Sir James was seen to have preserved his patient's comfort and dignity, at the same time advancing family and societal acceptance of the death of this matriarchal figure. © The Author 2014.

Queen Specific Exocrine Glands in Legionary Ants and Their Possible Function in Sexual Selection.

Science.gov (United States)

Hölldobler, Bert

2016-01-01

The colonies of army ants and some other legionary ant species have single, permanently wingless queens with massive post petioles and large gasters. Such highly modified queens are called dichthadiigynes. This paper presents the unusually rich exocrine gland endowment of dichthadiigynes, which is not found in queens of other ant species. It has been suggested these kinds of glands produce secretions that attract and maintain worker retinues around queens, especially during migration. However, large worker retinues also occur in non-legionary species whose queens do not have such an exuberance of exocrine glands. We argue and present evidence in support of our previously proposed hypothesis that the enormous outfit of exocrine glands found in dichthadiigynes is due to sexual selection mediated by workers as the main selecting agents.

Honey bees consider larval nutritional status rather than genetic relatedness when selecting larvae for emergency queen rearing.

Sagili, Ramesh R; Metz, Bradley N; Lucas, Hannah M; Chakrabarti, Priyadarshini; Breece, Carolyn R

2018-05-16

In honey bees and many other social insects, production of queens is a vital task, as colony fitness is dependent on queens. The factors considered by honey bee workers in selecting larvae to rear new queens during emergency queen rearing are poorly understood. Identifying these parameters is critical, both in an evolutionary and apicultural context. As female caste development in honey bees is dependent on larval diet (i.e. nutrition), we hypothesized that larval nutritional state is meticulously assessed and used by workers in selection of larvae for queen rearing. To test this hypothesis, we conducted a series of experiments manipulating the nutritional status of one day old larvae by depriving them of brood food for a four-hour period, and then allowing workers to choose larvae for rearing queens from nutritionally deprived and non-deprived larvae. We simultaneously investigated the role of genetic relatedness in selection of larvae for queen rearing. In all the experiments, significantly greater numbers of non-deprived larvae than deprived larvae were selected for queen rearing irrespective of genetic relatedness. Our results demonstrate that honey bees perceive the nutritional state of larvae and use that information when selecting larvae for rearing queens in the natural emergency queen replacement process.

Potential increase in mating frequency of queens in feral colonies of Bombus terrestris introduced into Japan

Science.gov (United States)

Inoue, Maki N.; Saito, Fuki; Tsuchida, Koji; Goka, Koichi

2012-10-01

With the exception of several species, bumblebees are monandrous. We examined mating frequency in feral colonies of the introduced bumblebee Bombus terrestris in Japan . Using microsatellite markers, genotyping of sperm DNA stored in the spermatheca of nine queens detected multiple insemination paternities in one queen; the others were singly mated. The average effective paternity frequency estimated from the genotypes of queens and workers was 1.23; that estimated from the workers' genotype alone was 2.12. These values were greater than those of laboratory-reared colonies in the native ranges of B. terrestris. The genotypes of one or two workers did not match those of their queens or showed paternities different from those of their nestmates; this may have arisen from either queen takeover or drifting of workers. These alien workers were responsible for the heterogeneous genotype distribution within each B. terrestris colony, resulting in higher estimates of paternity frequency than of insemination frequency. The high mating frequency of introduced B. terrestris may have occurred by artificial selection through mass breeding for commercialization. Moreover, polyandrous queens may be selectively advantageous, because reproduction by such queens is less likely to be disturbed by interspecific mating than that by monandrous queens.

Effect of cuticular abrasion and recovery on water loss rates in queens of the desert harvester ant Messor pergandei.

Science.gov (United States)

Johnson, Robert A; Kaiser, Alexander; Quinlan, Michael; Sharp, William

2011-10-15

Factors that affect water loss rates (WLRs) are poorly known for organisms in natural habitats. Seed-harvester ant queens provide an ideal system for examining such factors because WLRs for mated queens excavated from their incipient nests are twofold to threefold higher than those of alate queens. Indirect data suggest that this increase results from soil particles abrading the cuticle during nest excavation. This study provides direct support for the cuticle abrasion hypothesis by measuring total mass-specific WLRs, cuticular abrasion, cuticular transpiration, respiratory water loss and metabolic rate for queens of the ant Messor pergandei at three stages: unmated alate queens, newly mated dealate queens (undug foundresses) and mated queens excavated from their incipient nest (dug foundresses); in addition we examined these processes in artificially abraded alate queens. Alate queens had low WLRs and low levels of cuticle abrasion, whereas dug foundresses had high WLRs and high levels of cuticle abrasion. Total WLR and cuticular transpiration were lowest for alate queens, intermediate for undug foundresses and highest for dug foundresses. Respiratory water loss contributed ~10% of the total WLR and was lower for alate queens and undug foundresses than for dug foundresses. Metabolic rate did not vary across stages. Total WLR and cuticular transpiration of artificially abraded alate queens increased, whereas respiratory water loss and metabolic rate were unaffected. Overall, increased cuticular transpiration accounted for essentially all the increased total water loss in undug and dug foundresses and artificially abraded queens. Artificially abraded queens and dug foundresses showed partial recovery after 14 days.

Effect of a fungicide and spray adjuvant on queen-rearing success in honey bees (Hymenoptera: Apidae).

Science.gov (United States)

Johnson, Reed M; Percel, Eric G

2013-10-01

Commercial producers of honey bee queens (Apis mellifera L.) have reported unexplained loss of immature queens during the larval or pupal stage. Many affected queen-rearing operations are situated among the almond orchards of California and report these losses in weeks after almond trees bloom. Almond flowers are a rich foraging resource for bees, but are often treated with fungicides, insecticides, and spray adjuvants during bloom. Anecdotal reports by queen producers associate problems in queen development with application of the fungicide Pristine (boscalid and pyraclostrobin) and spray adjuvants that are tank-mixed with it. To test the effect of these compounds on queen development, a new bioassay was developed in which queens are reared in closed swarm boxes for 4 d, until capping, with nurse bees fed exclusively on artificially contaminated pollen. Pollen was treated with four concentrations of formulated Pristine (0.4, 4, 40, and 400 ppm), a spray adjuvant (Break-Thru, 200 ppm), the combination of Pristine and spray adjuvant (400:200 ppm), the insect growth regulator insecticide diflubenzuron (100 ppm) as a positive control, or water as negative control. Chemical analysis revealed that low concentrations of pyraclostrobin (50 ppb), but no boscalid, were detectable in royal jelly secreted by nurse bees feeding on treated pollen. No significant difference in queen development or survival was observed between any of the experimental treatments and the negative control. Only diflubenzuron, the positive control, caused a substantial reduction in survival of immature queens.

2012-01-01

Full Text Available Behavioral differentiation and ovarian development of unmated gynes, queens, and workers of Ectatomma vizottoi were investigated in laboratory conditions. Forty-one behavioral acts were identified and quantified for workers, 19 for queens and 24 for unmated gynes, for an overall species repertoire of 42 different behavioral acts. Ovipositing reproductive eggs was an exclusive task of the queen, whereas workers showed 15 caste-specific behaviors. The most important (frequent behaviors for the queens were brood care, immobility, and reproduction, and for workers were immobility, grooming/interaction, brood care, and foraging. Unmated gynes (not winged primarily showed immobility, brood care, grooming/interaction, and foraging. Analysis of ovarian development showed that unmated gynes had little-developed ovarioles, in contrast to queens. Queens and unmated gynes showed a clear behavioral differentiation, in which queens played the role of reproducers and unmated gynes performed activities belonging to the worker repertoire. Despite the presence of several breeding queens in the colony, functional monogyny was the rule.

Between 1841 and 1845 John Struthers attended both the University of Edinburgh and some of the various Extra-mural Schools of Medicine associated with Surgeons' Hall. While a medical student he became a Member of the Hunterian Medical Society of Edinburgh and later was elected one of their Annual Presidents. He graduated with the MD Edin and obtained both the LRCS Edin and the FRCS Edin diplomas in 1845. Shortly afterwards he was invited to teach Anatomy in Dr Handyside's Extra-mural School in Edinburgh. The College of Surgeons certified him to teach Anatomy in October 1847. He had two brothers, and all three read Medicine in Edinburgh. His younger brother, Alexander, died of cholera in the Crimea in 1855 while his older brother James, who had been a bachelor all his life, practised as a Consultant Physician in Leith Hospital, Edinburgh, until his death.When associated with Dr Handyside's Extra-mural School in Edinburgh, John taught Anatomy there until he was elected to the Chair of Anatomy in Aberdeen in 1863. Much of his time was spent in Aberdeen teaching Anatomy and in upgrading the administrative facilities there. He resigned from this Chair in 1889 and subsequently was elected President of Leith Hospital from 1891 to 1897. This was in succession to his older brother, James, who had died in 1891. Later, he was elected President of the Royal College of Surgeons of Edinburgh from 1895 to 1897 and acted as its Vice-President from 1897 until his death in 1899. In 1898, Queen Victoria knighted him. His youngest son, John William Struthers, was the only one of his clinically qualified sons to survive him and subsequently was elected President of the Edinburgh College of Surgeons from 1941 to 1943. © The Author(s) 2014.

In insect societies, chemical communication plays an important role in colony reproduction and individual social status. Many studies have indicated that cuticular hydrocarbons (CHCs) are the main chemical compounds encoding reproductive status. However, these studies have largely focused on queenless or monogynous species whose workers are capable of egg laying and have mainly explored the mechanisms underlying queen-worker or worker-worker reproductive conflicts. Less is known about what occurs in highly polygynous ant species with permanently sterile workers. Here, we used the Argentine ant as a model to examine the role of CHCs in communicating reproductive information in such insect societies. The Argentine ant is unicolonial, highly polygynous, and polydomous. We identified several CHCs whose presence and levels were correlated with queen age, reproductive status, and fertility. Our results also provide new insights into queen executions in the Argentine ant, a distinctive feature displayed by this species in its introduced range. Each spring, just before new sexuals appear, workers eliminate up to 90% of the mated queens in their colonies. We discovered that queens that survived execution had different CHC profiles from queens present before and during execution. More specifically, levels of some CHCs were higher in the survivors, suggesting that workers could eliminate queens based on their chemical profiles. In addition, queen CHC profiles differed based on season and species range (native vs. introduced). Overall, the results of this study provide new evidence that CHCs serve as queen signals and do more than just regulate worker reproduction. PMID:29470506

"Courageous, Zealous, Learned, Wise, and Chaste" - Queen Elizabeth I's Biblical Analogies After Her Death

Directory of Open Access Journals (Sweden)

Aidan Norrie

2015-11-01

Full Text Available During her reign, Queen Elizabeth I of England was the subject of various biblical analogies. Much of the current historiography, however, does not continue analysis of these literary devices after the Queen's death in 1603. Primary source documents show that their use did not cease with the Queen's death. These analogies appear to have continued for two primary purposes. Analogies legitimised a questionable event that had occurred during Elizabeth's reign, and portrayed these decisions as an example for the current Protestant monarch to imitate. Also, in the years after the Queen's death, analogies reinforced England's Protestantism (and its divine sanction, and gave the Stuart monarchs an example to emulate in religio-political matters.

Comparing alternative methods for holding virgin honey bee queens for one week in mailing cages before mating.

Full Text Available In beekeeping, queen honey bees are often temporarily kept alive in cages. We determined the survival of newly-emerged virgin honey bee queens every day for seven days in an experiment that simultaneously investigated three factors: queen cage type (wooden three-hole or plastic, attendant workers (present or absent and food type (sugar candy, honey, or both. Ten queens were tested in each of the 12 combinations. Queens were reared using standard beekeeping methods (Doolittle/grafting and emerged from their cells into vials held in an incubator at 34C. All 12 combinations gave high survival (90 or 100% for three days but only one method (wooden cage, with attendants, honey gave 100% survival to day seven. Factors affecting queen survival were analysed. Across all combinations, attendant bees significantly increased survival (18% vs. 53%, p<0.001. In addition, there was an interaction between food type and cage type (p<0.001 with the honey and plastic cage combination giving reduced survival. An additional group of queens was reared and held for seven days using the best method, and then directly introduced using smoke into queenless nucleus colonies that had been dequeened five days previously. Acceptance was high (80%, 8/10 showing that this combination is also suitable for preparing queens for introduction into colonies. Having a simple method for keeping newly-emerged virgin queens alive in cages for one week and acceptable for introduction into queenless colonies will be useful in honey bee breeding. In particular, it facilitates the screening of many queens for genetic or phenotypic characteristics when only a small proportion meets the desired criteria. These can then be introduced into queenless hives for natural mating or insemination, both of which take place when queens are one week old.

Queen influence on workers behavior of the leaf-cutting ant Atta sexdens rubropilosa (Forel, 1908

Directory of Open Access Journals (Sweden)

L. Sousa-Souto

Full Text Available In an ant colony, the queen is the single reproducer and can interact with her workers via pheromones and cuticular compounds. However, in most species queen importance is not restricted to reproduction: in the initial development of the colony, her presence might play a more important role. In this work, we studied the effects of queen absence on workers behavior displayed in the foraging arena. Ant’s mortality and refuse accumulation was also measured daily. The results showed that queen absence did not alter either workers behavior or foraging efficiency. However, we observed increased ant mortality accompanied by a decrease in refuse dumping outside the nest. These results corroborate the hypothesis that environmental factors are more important than intrinsical factors in the allocation of external tasks. Probably, the queen could only influence internal activities of the colony.

A distinct role of the queen in coordinated workload and soil distribution in eusocial naked mole-rats.

Directory of Open Access Journals (Sweden)

Nobuyuki Kutsukake

Full Text Available We investigated how group members achieve collective decision-making, by considering individual intrinsic behavioural rules and behavioural mechanisms for maintaining social integration. Using a simulated burrow environment, we investigated the behavioural rules of coordinated workload for soil distribution in a eusocial mammal, the naked mole-rat (Heterocephalus glaber. We tested two predictions regarding a distinct role of the queen, a socially dominant individual in the caste system: the presence of a queen would increase the workload of other caste individuals, and the cues by a queen would affect the soil distribution. In experiment 1, we placed four individuals of various castes from the same colony into an experimental burrow. Workers exhibited the highest frequency of workload compared to other castes. The presence of a queen activated the workload by other individuals. Individuals showed a consistent workload in a particular direction so as to bias the soil distribution. These results suggest that individuals have a consensus on soil distribution and that the queen plays a distinct role. In experiment 2, we placed the odour of a queen in one of four cells and observed its effect on other individuals' workload and soil distribution. Relative to other cells, individuals frequently dug in the queen cell so the amount of soil in the queen cell decreased. These results suggest that queen odour is an important cue in coordinated workload and soil distribution in this species.

How Complex, Probable, and Predictable is Genetically Driven Red Queen Chaos?

Duarte, Jorge; Rodrigues, Carla; Januário, Cristina; Martins, Nuno; Sardanyés, Josep

2015-12-01

Coevolution between two antagonistic species has been widely studied theoretically for both ecologically- and genetically-driven Red Queen dynamics. A typical outcome of these systems is an oscillatory behavior causing an endless series of one species adaptation and others counter-adaptation. More recently, a mathematical model combining a three-species food chain system with an adaptive dynamics approach revealed genetically driven chaotic Red Queen coevolution. In the present article, we analyze this mathematical model mainly focusing on the impact of species rates of evolution (mutation rates) in the dynamics. Firstly, we analytically proof the boundedness of the trajectories of the chaotic attractor. The complexity of the coupling between the dynamical variables is quantified using observability indices. By using symbolic dynamics theory, we quantify the complexity of genetically driven Red Queen chaos computing the topological entropy of existing one-dimensional iterated maps using Markov partitions. Co-dimensional two bifurcation diagrams are also built from the period ordering of the orbits of the maps. Then, we study the predictability of the Red Queen chaos, found in narrow regions of mutation rates. To extend the previous analyses, we also computed the likeliness of finding chaos in a given region of the parameter space varying other model parameters simultaneously. Such analyses allowed us to compute a mean predictability measure for the system in the explored region of the parameter space. We found that genetically driven Red Queen chaos, although being restricted to small regions of the analyzed parameter space, might be highly unpredictable.

History has well documented the execution of Queen Ketevan of Georgia by the Persian Emperor of modern day Iran. Based on historical records, in 1624 two Augustinian friars unearthed the queen's remains and one of them brought the relic to the St. Augustine convent in Goa, India. We carried out ancient DNA analysis on the human bone remains excavated from the St. Augustine convent by sequencing and genotyping of the mitochondrial DNA. The investigations of the remains revealed a unique mtDNA haplogroup U1b, which is absent in India, but present in Georgia and surrounding regions. Since our genetic analysis corroborates archaeological and literary evidence, it is likely that the excavated bone belongs to Queen Ketevan of Georgia. Copyright © 2013 Elsevier B.V.

Epidemiology of a Daphnia-multiparasite system and its implications for the red queen.

Science.gov (United States)

Auld, Stuart K J R; Hall, Spencer R; Duffy, Meghan A

2012-01-01

The Red Queen hypothesis can explain the maintenance of host and parasite diversity. However, the Red Queen requires genetic specificity for infection risk (i.e., that infection depends on the exact combination of host and parasite genotypes) and strongly virulent effects of infection on host fitness. A European crustacean (Daphnia magna)--bacterium (Pasteuria ramosa) system typifies such specificity and high virulence. We studied the North American host Daphnia dentifera and its natural parasite Pasteuria ramosa, and also found strong genetic specificity for infection success and high virulence. These results suggest that Pasteuria could promote Red Queen dynamics with D. dentifera populations as well. However, the Red Queen might be undermined in this system by selection from a more common yeast parasite (Metschnikowia bicuspidata). Resistance to the yeast did not correlate with resistance to Pasteuria among host genotypes, suggesting that selection by Metschnikowia should proceed relatively independently of selection by Pasteuria.

Estes dados foram obtidos através de pesquisa exploratória com três sujeitos através de entrevistas, sendo o roteiro semidirigido, além de terem sido realizadas visitas em suas moradias e em casas noturnas onde faziam apresentações artísticas. Os entrevistados relataram que a identidade das drags se diferencia de suas identidades pessoais em diversos aspectos. A drag possui características físicas e psicológicas, além de posturas e atitudes, que são próprias da personagem e que a distinguem do sujeito que a compõe. Mas houve relatos com freqüência que existem situações em que personagem e sujeito que a compõe se confundem. Através dos resultados, pode-se identificar como a configuração da identidade está relacionada com a socialização e com as transformações do corpo. Os sujeitos que interpretam as drag queens manifestam esse jogo de identidades, de ambos os gêneros, configurando o que pode se identificar com uma identidade queer.The main objective of this study was to identify the formation process of queer identity of some drag queens in the cities of Balneário Camboriú and Florianópolis, in the state of Santa Catarina, south of Brazil.

Full Text Available Protein content of leaf-cutting ant queens before the nuptial flight and during the post-claustral phase. This study evaluated the crude protein content of queens of Atta sexdens before the nuptial flight and after the claustral phase in laboratory and field colonies. The hypothesis was that protein is used for survival of the queen and for early colony growth during the claustral phase. Additionally, the nest morphology, live biomass and adult population of field colonies were evaluated. Crude protein was determined by digestion of the organic material with sulfuric acid at high temperatures. The mean crude protein content was 123.23 ± 11.20 mg for females before the nuptial flight and 70.44 ± 12.21 mg for laboratory-reared queens after the claustral phase. The post-claustral crude protein content of field-collected queen was 55.90 ± 9.18 mg. With respect to the loss of crude protein as a function of duration of the claustral phase, laboratory-reared queens lost 52.79 mg and field-collected queens lost 67.33 mg compared to females before the nuptial flight. A positive linear correlation was observed between the weight of field-collected queens (256.4 ± 36.3 mg and colony biomass (13.02 ± 9.12 g, but there was no correlation between biomass and nest depth (13.11 ± 3.82 cm. As expected, the present results support the hypothesis that protein is used for survival of the queen and for early colony growth, as demonstrated by the reduction in crude protein content as a function of duration of the claustral phase. To our knowledge, this is the first study to provide data of the dynamics of protein reserves in leaf-cutting ant queens during the claustral phase.

2002-12-01

The NASA/USRA Cooperative University-based Program in Earth System Science Education (ESSE), initiated over a decade ago through NASA support, has led in the creation of a nationwide collaborative effort to bring Earth system science into the undergraduate classroom. Forty-five ESSE institutions now offer over 120 Earth system courses each year, reaching thousands of students annually with interdisciplinary content. Through the course offerings by faculty from different disciplines and the organizational infrastructure of colleges and universities emphasizing cross disciplinary curricula, programs, degrees and departments, the ESSE Program has led in systemic change in the offering of a holistic view of Earth system science in the classroom. Building on this successful experience and collaborative infrastructure within and among colleges, universities and NASA partners, an expanded program called ESSE 21 is being supported by NASA to extend the legacy established during the last decade. Through its expanded focus including partnerships with under represented colleges and universities, the Program seeks to further develop broadly based educational resources, including shared courses, electronic learning materials and degree programs that will extend Earth system science concepts in both undergraduate and graduate classrooms and laboratories. These resources emphasizing fundamentals of Earth system science advance the nation's broader agenda for improving science, technology, engineering and mathematics competency. Overall the thrust within the classrooms of colleges and universities is critical to extending and solidifying courses of study in Earth system and global change science. ESSE 21 solicits proposals from undergraduate institutions to create or adopt undergraduate and graduate level Earth system science content in courses, curricula and degree programs. The goal for all is to effect systemic change through developing Earth system science learning materials

Genomic analysis of post-mating changes in the honey bee queen (Apis mellifera

Richard Freddie-Jeanne

2008-05-01

Full Text Available Abstract Background The molecular mechanisms underlying the post-mating behavioral and physiological transitions undergone by females have not been explored in great detail. Honey bees represent an excellent model system in which to address these questions because they exhibit a range of "mating states," with two extremes (virgins and egg-laying, mated queens that differ dramatically in their behavior, pheromone profiles, and physiology. We used an incompletely-mated mating-state to understand the molecular processes that underlie the transition from a virgin to a mated, egg-laying queen. We used same-aged virgins, queens that mated once but did not initiate egg-laying, and queens that mated once and initiated egg-laying. Results Differences in the behavior and physiology among groups correlated with the underlying variance observed in the top 50 predictive genes in the brains and the ovaries. These changes were correlated with either a behaviorally-associated pattern or a physiologically-associated pattern. Overall, these results suggest that the brains and the ovaries of queens are uncoupled or follow different timescales; the initiation of mating triggers immediate changes in the ovaries, while changes in the brain may require additional stimuli or take a longer time to complete. Comparison of our results to previous studies of post-mating changes in Drosophila melanogaster identified common biological processes affected by mating, including stress response and alternative-splicing pathways. Comparison with microarray data sets related to worker behavior revealed no obvious correlation between genes regulated by mating and genes regulated by behavior/physiology in workers. Conclusion Studying the underlying molecular mechanisms of post-mating changes in honey bee queens will not only give us insight into how molecular mechanisms regulate physiological and behavioral changes, but they may also lead to important insights into the evolution of

Universities Space Research Association and Sinte Gleska University (SGU) have teamed with eight Tribal Colleges and Universities (TCUs) to participate in a NASA Earth Science funded project, TRibal Earth Science and Technology Education (TRESTE) project which focuses on TCU faculty teaching undergraduate Earth science courses to non-science and science students, with particular attention to TCU faculty teaching K-12 pre- and in- service teachers. The eight partner TCUs are: Blackfeet Community College (BCC), Browning, MT, Fond du Lac Tribal and Community College, Cloquet, MN, Fort Berthold Community College, New Town, ND, Little Priest Tribal College, Winnebago, NE, Oglala Lakota College, Pine Ridge, SD, Sitting Bull College, Fort Yates, ND, Turtle Mountain Community College, Belcourt, ND, United Tribes Technical College (UTTC), Bismarck, ND. The goal of this 3-year project is to promote the use of NASA Earth science data and products in the classroom thereby enabling faculty to inspire undergraduate students to careers in Earth system science, the physical sciences, and related fields of science and engineering. To accomplish this goal we are targeting three areas: (1) course content - enhance the utilization of Earth system science and physical science concepts, (2) teaching methodology - develop problem-based learning (PBL) methods, and (3) tools and technology - increase the utilization of GIS and remote sensing in the classroom. We also have enlisted ESRI, NativeView and the USGS as collaborators. To date we have held an introductory "needs" workshop at the USGS EROS Data Center and two annual workshops, one at UTTC and the second at BCC. During these annual workshops we have divided our time among the three areas. We have modeled the workshops using the PBL or Case Study approach by starting with a story or current event. Topics for the annual workshops have been Drought and Forest and Grassland Fires. These topics led us into the solar radiation budget

The Kilimanjaro Christian Medical University (KCMU) College and the Medical Education Partnership Initiative (MEPI) are addressing the crisis in Tanzanian health care manpower by modernizing the college’s medical education with new tools and techniques. With a $10 million MEPI grant and the participation of its partner, Duke University, KCMU is harnessing the power of information technology (IT) to upgrade tools for students and faculty. Initiatives in eLearning have included bringing fiber-optic connectivity to the campus, offering campus-wide wireless access, opening student and faculty computer laboratories, and providing computer tablets to all incoming medical students. Beyond IT, the college is also offering wet laboratory instruction for hands-on diagnostic skills, team-based learning, and clinical skills workshops. In addition, modern teaching tools and techniques address the challenges posed by increasing numbers of students. To provide incentives for instructors, a performance-based compensation plan and teaching awards have been established. Also for faculty, IT tools and training have been made available, and a medical education course management system is now being widely employed. Student and faculty responses have been favorable, and the rapid uptake of these interventions by students, faculty, and the college’s administration suggests that the KCMU College MEPI approach has addressed unmet needs. This enabling environment has transformed the culture of learning and teaching at KCMU College, where a path to sustainability is now being pursued. PMID:25072581

Functional morphology of the postpharyngeal gland of queens and workers of the ant Monomorium pharaonis (L.)

DEFF Research Database (Denmark)

Eelen, Dieter; Børgesen, Lisbeth W.; Billen, Johan

2006-01-01

the PPG morphology varies considerably according to age and mating status. The epithelial thickness increases with age and reaches a maximum at 3 weeks in both virgin and mated queens. A considerable expansion of the lumen diameter occurs in both groups between 4 and 7 days. Virgin queens release...... nurses and foragers. We suggest the PPG serves different purposes in pharaoh's ants: it is likely that the PPG of workers and virgin queens is used to feed larvae. In mated queens the gland probably plays a role in providing the queen with nutritious oils for egg production. The PPG may also function...

Adapting an Evidence-Based HIV Intervention for At-Risk African American College Women at Historically Black Colleges and Universities Who Use Alcohol and Drugs

Directory of Open Access Journals (Sweden)

Full Text Available The convergence of the high prevalence of HIV incidence among African American adolescent and adult women along with substance use and risky sexual behavior among university students necessitates the development of a HIV intervention specifically addressing culture, gender, and college factors for female African American university students. The woman-focused HIV intervention was chosen for adaptation because it has been shown to be efficacious with reducing risk for African American women who use alcohol and drugs, and has been successfully adapted 7 times. The target population was African American college women enrolled at a historically Black university who use alcohol and other drugs, and who engaged in risky sex behaviors. To understand and assess the needs of this population, we conducted four focus groups with African American college women, two in-depth interviews with faculty, and a combination of in-depth interviews and focus groups with student affairs and health staff that were analyzed using content analysis. From this analysis, several themes emerged that were used to adapt the intervention. Emerging themes included challenges related to identity and societal stereotypes, lack of knowledge about sexual health (i.e., negotiating safer sex and the function of female and male anatomies, high incidents of pregnancy, negative consequences related to alcohol and marijuana use, and the need to incorporate testimonies from college students, media enhancements, and role-plays to convey intervention messages. After the preliminary adaptation, 11 college women reviewed the adapted intervention and provided positive feedback. Plans for future research are discussed.

2002-05-01

Full Text Available Total amount of 4.355 records of honeybee colonies production characteristics was estimated on the 251 bee yards in Slovenia from 1993 to 2001. Queens were produced on 29 queen producing yards. The average lsmeans of honey yields increased by 0,41 kg a year. The swarming behaviour and the defensive behaviour of bees increased as well by - 0,091 points, and –0,038 points respectively. According to the last two years records, the honey yields of bee colonies were significantly influenced by the drone gene pool at queen production yards. The swarming behaviour was in contrary more influenced by the queen mothers on queen production yards. The defensive behaviour of bee colonies and the daily varroa mite fall were not significantly influenced by parents.

Red Queen Processes Drive Positive Selection on Major Histocompatibility Complex (MHC Genes.

Directory of Open Access Journals (Sweden)

Maciej Jan Ejsmond

2015-11-01

Full Text Available Major Histocompatibility Complex (MHC genes code for proteins involved in the incitation of the adaptive immune response in vertebrates, which is achieved through binding oligopeptides (antigens of pathogenic origin. Across vertebrate species, substitutions of amino acids at sites responsible for the specificity of antigen binding (ABS are positively selected. This is attributed to pathogen-driven balancing selection, which is also thought to maintain the high polymorphism of MHC genes, and to cause the sharing of allelic lineages between species. However, the nature of this selection remains controversial. We used individual-based computer simulations to investigate the roles of two phenomena capable of maintaining MHC polymorphism: heterozygote advantage and host-pathogen arms race (Red Queen process. Our simulations revealed that levels of MHC polymorphism were high and driven mostly by the Red Queen process at a high pathogen mutation rate, but were low and driven mostly by heterozygote advantage when the pathogen mutation rate was low. We found that novel mutations at ABSs are strongly favored by the Red Queen process, but not by heterozygote advantage, regardless of the pathogen mutation rate. However, while the strong advantage of novel alleles increased the allele turnover rate, under a high pathogen mutation rate, allelic lineages persisted for a comparable length of time under Red Queen and under heterozygote advantage. Thus, when pathogens evolve quickly, the Red Queen is capable of explaining both positive selection and long coalescence times, but the tension between the novel allele advantage and persistence of alleles deserves further investigation.

The origin and evolution of queen and fertility signals in Corbiculate bees.

In social Hymenoptera (ants, bees and wasps), various chemical compounds present on the cuticle have been shown to act as fertility signals. In addition, specific queen-characteristic hydrocarbons have been implicated as sterility-inducing queen signals in ants, wasps and bumblebees. In Corbiculate bees, however, the chemical nature of queen-characteristic and fertility-linked compounds appears to be more diverse than in ants and wasps. Moreover, it remains unknown how queen signals evolved across this group and how they might have been co-opted from fertility signals in solitary ancestors. Here, we perform a phylogenetic analysis of fertility-linked compounds across 16 species of solitary and eusocial bee species, comprising both literature data as well as new primary data from a key solitary outgroup species, the oil-collecting bee Centris analis, and the highly eusocial stingless bee Scaptotrigona depilis. Our results demonstrate the presence of fertility-linked compounds belonging to 12 different chemical classes. In addition, we find that some classes of compounds (linear and branched alkanes, alkenes, esters and fatty acids) were already present as fertility-linked signals in the solitary ancestors of Corbiculate bees, while others appear to be specific to certain species. Overall, our results suggest that queen signals in Corbiculate bees are likely derived from ancestral fertility-linked compounds present in solitary bees that lacked reproductive castes. These original fertility-linked cues or signals could have been produced either as a by-product of ovarian activation or could have served other communicative purposes, such as in mate recognition or the regulation of egg-laying.

Experiential Learning for Native American Students at Tribal Colleges and Universities

Sauve, M. L.; Moore, K.

2003-12-01

In reaffirming its commitment to Indian tribes and Alaska Native entities, the Federal Government issued Executive Order 13270 of July 3, 2002, stating the policy that " this Nation's commitment to education excellence and opportunity must extend as well to the tribal colleges and universities." Further, the Federal Government has called on the private sector to contribute to these colleges' educational and cultural mission. American University, through its American Indian Internship Program, has responded to this call. American University, a private liberal arts institution of higher education in the Nation's capital, has long ago recognized the importance of experiential learning in undergraduate education. For over 50 years, its Washington Semester Program brings students from other universities around the country and the world to American University's campus and to Washington, D.C. for a unique academic experience. The Washington Semester Program combines academic seminars in various fields of concentration with internship work in government agencies, congressional offices, non-profit organizations, foundations and research institutions in the Nation's capital. Students in this Program get to meet the Nation's leaders, experts in the field, and notable newsmakers while incorporating their academic skills and courses in practice at their internship assignments. The American Indian Internship Program (also knows as Washington Internship for Native Students-WINS) is one of the programs in Washington Semester. This program is designed to give American Indian students the chance to study issues of interest to the Native community and to gain valuable work experience through an internship in the Nation's capital. All costs to attend the program are paid by the internship sponsors and American University, including transportation between the students' home and Washington, DC, tuition and program fees for 6 credit hours in the summer and 12 credit hours in fall

Bahreini, Rassol; Currie, Robert W

2015-07-01

The objective of this study was to assess the effects of honey bees (Apis mellifera L.) with different grooming ability and queen pheromone status on mortality rates of Varroa mites (Varroa destructor Anderson and Trueman), mite damage, and mortality rates of honey bees. Twenty-four small queenless colonies containing either stock selected for high rates of mite removal (n = 12) or unselected stock (n = 12) were maintained under constant darkness at 5 °C. Colonies were randomly assigned to be treated with one of three queen pheromone status treatments: (1) caged, mated queen, (2) a synthetic queen mandibular pheromone lure (QMP), or (3) queenless with no queen substitute. The results showed overall mite mortality rate was greater in stock selected for grooming than in unselected stock. There was a short term transitory increase in bee mortality rates in selected stock when compared to unselected stock. The presence of queen pheromone from either caged, mated queens or QMP enhanced mite removal from clusters of bees relative to queenless colonies over short periods of time and increased the variation in mite mortality over time relative to colonies without queen pheromone, but did not affect the proportion of damaged mites. The effects of source of bees on mite damage varied with time but damage to mites was not reliably related to mite mortality. In conclusion, this study showed differential mite removal of different stocks was possible under low temperature. Queen status should be considered when designing experiments using bioassays for grooming response.

Mating with an allopatric male triggers immune response and decreases longevity of ant queens.

Schrempf, A; von Wyschetzki, K; Klein, A; Schrader, L; Oettler, J; Heinze, J

2015-07-01

In species with lifelong pair bonding, the reproductive interests of the mating partners are aligned, and males and females are expected to jointly maximize their reproductive success. Mating increases both longevity and fecundity of female reproductives (queens) of the ant Cardiocondyla obscurior, indicating a tight co-evolution of mating partners. Here, we show that mating with a male from their own population increases lifespan and reproductive success of queens more than mating with a male from a different population, with whom they could not co-evolve. A comparison of transcriptomes revealed an increased expression of genes involved in immunity processes in queens, which mated with males from a different population. Increased immune response might be proximately associated with decreased lifespan. Our study suggests a synergistic co-evolution between the sexes and sheds light on the proximate mechanisms underlying the decreased fitness of allopatrically mated queens. © 2015 John Wiley & Sons Ltd.

The queen conch ( Strombus gigas) is a commercially important marine invertebrate that is widely distributed throughout the western Atlantic, from Bermuda to Brazil. Intense exploitation has resulted in a decrease in population numbers of this species, which is listed as protected from commercial exploitation under IUCN and CITES. Previous studies on population genetics have demonstrated contrasting results in terms of the population structure of S. gigas. This research analyzed the genetic connectivity of the queen conch over a wide area of the Mesoamerican Reef System to determine whether S. gigas presents one panmictic population or a more complex structure. Furthermore, we evaluated the risk of local extinction by establishing the genetic diversity of the studied populations. High resolution was obtained for the five ISSR markers used for a total of 190 individuals, from seven localities along the Mesoamerican Reef. Our results reject the panmictic structure hypothesis for the queen conch in the study area and demonstrate genetic patchiness, indicating general homogeneity among localities that present an isolation-by-distance pattern. However, some genetic temporal variation was confirmed for the Cozumel locality. Furthermore, our results reveal self-recruitment for the Alacranes Reef aggregation and suggest sufficient connectivity with localities on the Caribbean coast to maintain high genetic diversity. With regard to genetic diversity, the results demonstrate that the queen conch is not genetically threatened in the study area. This is probably due to high annual recruitment within Caribbean queen conch aggregations, and suggests that S. gigas is a highly resilient organism. We advocate that the appropriate management of S. gigas (fishing quota and/or closed season) must be followed to attain a rapid recovery of queen conch populations. This study represents a fundamental step in the understanding of the dynamic population structure of S. gigas in the

When invasive ants meet: effects of outbreeding on queen performance in the tramp ant Cardiocondyla itsukii.

Science.gov (United States)

Heinze, Jürgen; Frohschammer, Sabine; Bernadou, Abel

2017-08-18

Most disturbed habitats in the tropics and subtropics harbor numerous species of invasive ants, and occasionally the same species has been introduced repeatedly from multiple geographical sources. We examined how experimental crossbreeding between sexuals from different populations affects the fitness of queens of the tramp ant Cardiocondyla itsukii, which is widely distributed in Asia and the Pacific Islands. Eggs laid by queens that mated with nestmate males had a higher hatching rate than eggs laid by queens mated to males from neighboring (Hawaii × Kauai) or distant introduced populations (Hawaii/Kauai × Okinawa). Furthermore, inbreeding queens had a longer lifespan and produced a less female-biased offspring sex ratio than queens from allopatric mating. This suggests that the genetic divergence between different source populations may already be so large that in case of multiple invasions eventual crossbreeding might negatively affect the fitness of tramp ants. © 2017 Institute of Zoology, Chinese Academy of Sciences.

The Effect of Open Brood and Colony Strength on the Onset of Oviposition by Queen Bees

Directory of Open Access Journals (Sweden)

Gąbka Jakub

2014-06-01

Full Text Available In bee colonies without open brood, e.g., after swarming, there is no need for royal jelly, and nurse bees thus do not produce it. According to many beekeepers, adding combs with open brood restarts the production of royal jelly by nurse bees, and the virgin queens then are better fed and start earlier oviposition. The purpose of this study was to investigate whether the presence of open brood and the strength of the colonies affect the onset of oviposition by queen bees. Open brood in colonies with virgins before and during mating flights did not accelerate the initiation of oviposition by the queens. In addition, no differences were identified in starting oviposition by queens in strong colonies of more than 30,000 worker bees, or in weak colonies with up to 1,000 workers. Overall, the results showed that neither open brood in the nests, nor the strength of the colonies affects the onset of oviposition by queen bees.

With the enrollment of more diverse college learners comes a call to intentionally design instruction that is more inclusive and responsive to multiple learning styles. The notion of Universal Design for Instruction (UDI is examined from its roots in the architectural field to its application as a model for teaching that anticipates diversity including students with disabilities. Principles of UDI are defined, and pedagogical examples are provided. Several implementation projects based on the UDI concept are described as are preliminary results regarding outcomes. Substantive issues are identified that have bearing on the direction this innovative idea will take over the next several years.

The Institute of Epileptology of King's College, University of London.

Science.gov (United States)

Reynolds, E H

1995-01-01

The Institute of Epileptology of King's College, London has arisen from need and from opportunity. The need is due to the relative neglect nationally and internationally of the most common serious brain disorder with important physical, psychological, and social complications. The relative neglect is reflected in services, research, charitable donations, public profile, and stigma and in a serious lack of professional education. The opportunity arose because of the existence in several medical institutions at Denmark Hill, London, of a group of medical and related colleagues with a special interest covering almost every aspect of this multidisciplinary disorder who agreed to combine their expertise in this initiative. The idea was born and developed in 1991-1992 and was supported by all the parent institutions: The Maudsley and King's College Hospitals, St. Piers Lingfield, The Institute of Psychiatry, King's College School of Medicine and Dentistry, and the School of Life, Basic Medical and Health Sciences, all under the umbrella of King's College, University of London. Further stimulus and help came from a group of dedicated supporters in private and public life. There are three strands to this initiative: (a) a charity, The Fund for Epilepsy; (b) the clinical Centre for Epilepsy, which was formally opened at the Maudsley Hospital in July 1994; and (c) the academic Institute of Epileptology for research and teaching, which was launched on November 15, 1994.

Sex allocation in fungus-growing ants: worker or queen control without symbiont-induced female bias

DEFF Research Database (Denmark)

Dijkstra, Michiel B.; Boomsma, Jacobus Jan

2008-01-01

The fungal cultivars of fungus-growing ants are vertically transmitted by queens but not males. Selection would therefore favor cultivars that bias the ants' sex ratio towards gynes, beyond the gyne bias that is optimal for workers and queens. We measured sex allocation in 190 colonies of six...... sympatric fungus-growing ant species. As predicted from relatedness, female bias was greater in four singly mated Sericomyrmex and Trachymyrmex species than in two multiply mated Acromyrmex species. Colonies tended to raise mainly a single sex, which could be partly explained by variation in queen number......, colony fecundity, and fungal garden volume for Acromyrmex and Sericomyrmex, but not for Trachymyrmex. Year of collection, worker number and mating frequency of Acromyrmex queens did not affect the colony sex ratios. We used a novel sensitivity analysis to compare the population sex allocation ratios...

To understand the prevalence and risk factors for suicidal ideation among college students and to provide a scientific basis for promoting psychological health and suicide prevention. 623 college students at Central South University were selected using stratified cluster sampling and administered a suicide ideation questionnaire, a Symptom Check List (SCL-90), an Adolescent Self-Rating Life Events Check List (ASLEC), a Social Support Rating Scale (SSRS) and a questionnaire about background information. Multivariate logistic regression analysis was employed to identify risk factors for suicide ideation. One year prior to our investigation, 14.6% of respondents had suicide ideation, 2.5% had made a specific suicide plan, and 1.8% had made a suicide attempt. The main risk factors for suicide ideation were dissatisfaction with the selected major of study, limited social support, recent negative life events and depressive tendency. The prevalence of suicide ideation among these college students was high. Appropriate measures focusing on the risk factors identified in this study should be urgently developed to prevent suicides in college students.

Modifications in the oviducts of workers and queens of Melipona quadrifasciata anthidioides (Hymenoptera: Apidae) with different ages.

Science.gov (United States)

Serrão, José Eduardo; Naves, Amanda Paula; Zanuncio, José Cola

2011-10-01

The study of morphological features of highly eusocial bees has helped to answer a series of questions concerning their biology. The labor division places the females into two castes, queen with reproductive function and worker with a wide variety of tasks. However, in different species and under different conditions, workers can develop ovaries and lay trophic eggs that are eaten by the queen or used to originate males. In this work, the development of the oviducts was monitored in workers and virgin queens of Melipona quadrifasciata anthidioides specimens of different ages to verify whether there is permanent sterility of these queens and workers due to aging. Lateral and common oviducts of virgin queens aged <7, 10, 15, 20, and 25 days old, physogastric queens, nurse, and forager workers were analyzed for histology and ultrastructure. Although the structural organization of the lateral and common oviducts were very similar, differences in width of the cuticle and the degree of chromatin condensation were observed, indicating differences in the development of this organ of the reproductive system between the castes. It was also demonstrated that electron-lucent vesicles appear to be related to the formation of the cuticle that lines the oviducts. Because no cellular death characteristics were found, it can be inferred that the absence of mating of the queens as old as of 25 days of age does not cause permanent sterility.

Conserved queen pheromones in bumblebees: a reply to Amsalem et al.

Directory of Open Access Journals (Sweden)

Luke Holman

2017-05-01

Full Text Available In a recent study, Amsalem, Orlova & Grozinger (2015 performed experiments with Bombus impatiens bumblebees to test the hypothesis that saturated cuticular hydrocarbons are evolutionarily conserved signals used to regulate reproductive division of labor in many Hymenopteran social insects. They concluded that the cuticular hydrocarbon pentacosane (C25, previously identified as a queen pheromone in a congeneric bumblebee, does not affect worker reproduction in B. impatiens. Here we discuss some shortcomings of Amsalem et al.’s study that make its conclusions unreliable. In particular, several confounding effects may have affected the results of both experimental manipulations in the study. Additionally, the study’s low sample sizes (mean n per treatment = 13.6, range: 4–23 give it low power, not 96–99% power as claimed, such that its conclusions may be false negatives. Inappropriate statistical tests were also used, and our reanalysis found that C25 substantially reduced and delayed worker egg laying in B. impatiens. We review the evidence that cuticular hydrocarbons act as queen pheromones, and offer some recommendations for future queen pheromone experiments.

Minority stress and college persistence attitudes among African American, Asian American, and Latino students: perception of university environment as a mediator.

Science.gov (United States)

Wei, Meifen; Ku, Tsun-Yao; Liao, Kelly Yu-Hsin

2011-04-01

We examined whether perception of university environment mediated the association between minority status stress and college persistence attitudes after controlling for perceived general stress. Participants were 160 Asian American, African American, and Latino students who attended a predominantly White university. Results of a path model analysis showed that university environment was a significant mediator for the association between minority status stress and college persistence attitudes. Additionally, minority status stress was distinct from perceived general stress. Finally, the results from a multiple-group comparison indicated that the magnitude of the mediation effect was invariant across Asian American, African American, and Latino college students, thus supporting the generalizability of the mediation model.

2016-05-01

Full Text Available ABSTRACT: The objective of this research was to evaluate the honey production per hive and the egg laying rates of queens produced in 2007, 2008 and 2010. Thirty colonies initiated with a queen per colony at each climatic season were used during the three years. The years, started on January (summer, April (autumn, July (winter and October (spring and ended 12 months later, at the same periods related to each season of the later years. Honey supply were weighed before and after centrifugation to evaluate the quantity of the stored honey. Colonies with queens introduced during autumn and winter in the three years produced 57.2±6.0kg and 60.7±7.5kg of honey, respectively. In the first year of production activity, after the introduction of queens in the initial colonies, values were significantly higher than those obtained in colonies with queens introduced in the summer (39.3±7.6kg and spring (41.8±3.7kg. Egg laying rates of queens were higher in spring (98.2±3.9% and summer (88.4±7%, indicating greater food flow (flowerings in these seasons compared to the averages in autumn (30.3±8.1% and winter (24.5±7.2%. Produce and introduce queens of Africanized Apis mellifera in colonies initiated during autumn and winter was found to be economically feasible. Honey production of colonies initiated in these periods were higher and they had greater population stability in times of scarcity of flowerings.

2016-01-01

The purpose of this study was to examine the relationship between depressive symptomatology and college outcomes among African American students, as well as to determine whether these relationships were moderated by gender and type of university. Participants included 569 African American first-year students attending two public universities in the Southeast United States: a historically Black college/university (HBCU) and a predominantly White institution (PWI). Using a longitudinal study design, data were collected at three time points. Results indicated that, after adjusting for the effects of the control variables (gender, type of institution, high school GPA, participation in on-campus activities, institutional and goal commitments), depressive symptomatology present in the first semester of college was associated with increased likelihood of dropping out of college before the end of the second year of college. The relationship between these two variables was mediated by first-year cumulative GPA. Results also indicated that the hypothesized relationships did not vary as a function of gender and the university type.

Founding weaver ant queens (Oecophylla longinoda) increase production and nanitic worker size when adopting non-nestmate pupae.

Ouagoussounon, Issa; Offenberg, Joachim; Sinzogan, Antonio; Adandonon, Appolinaire; Kossou, Dansou; Vayssières, Jean-François

2015-01-01

Weaver ants (Oecophylla longinoda Latreille) are used commercially to control pest insects and for protein production. In this respect fast colony growth is desirable for managed colonies. Transplantation of non-nestmate pupae to incipient colonies has been shown to boost colony growth. Our objectives were to find the maximum number of pupae a founding queen can handle, and to measure the associated colony growth. Secondly, we tested if transplantation of pupae led to production of larger nanitic workers (defined as unusually small worker ants produced by founding queens in their first batch of offspring). Forty-five fertilized queens were divided into three treatments: 0 (control), 100 or 300 non-nestmate pupae transplanted to each colony. Pupae transplantation resulted in highly increased growth rates, as pupae were readily adopted by the queens and showed high proportions of surviving (mean = 76%). However, survival was significantly higher when 100 pupae were transplanted compared to transplantation of 300 pupae, indicating that queens were unable to handle 300 pupae adequately and that pupae require some amount of nursing. Nevertheless, within the 60-day experiment the transplantation of 300 pupae increased total colony size more than 10-fold whereas 100 pupae increased the size 5.6 fold, compared to control. This increase was due not only to the individuals added in the form of pupae but also to an increased per capita brood production by the resident queen, triggered by the adopted pupae. The size of hatching pupae produced by the resident queen also increased with the number of pupae transplanted, leading to larger nanitic workers in colonies adopting pupae. In conclusion, pupae transplantation may be used to produce larger colonies with larger worker ants and may thus reduce the time to produce weaver ant colonies for commercial purposes. This in turn may facilitate the implementation of the use of weaver ants.

Male scent-marking pheromone of Bombus ardens ardens (Hymenoptera; Apidae) attracts both conspecific queens and males

Science.gov (United States)

Kubo, Ryohei; Harano, Ken-ichi; Ono, Masato

2017-10-01

To explore the role of the volatiles emitted from male labial gland (LG) of the bumblebee Bombus ardens ardens, we investigated the responses of virgin queens and males to volatiles using a gas chromatography-electroantennographic detector (GC-EAD) system and Y-tube olfactometer. GC-EAD analysis revealed that citronellol, the main compound detected in the male LG, caused clear electrophysiological responses in the antennae of B. a. ardens virgin queens and males although two minor compounds elicited antennal responses when applied in a high concentration. Behavioral tests using a Y-tube olfactometer showed that queens and males were significantly attracted to both LG extracts and citronellol more than to the solvent alone. This is the first study to demonstrate that citronellol as a major compound of male scent-marking pheromone in B. a. ardens functions as a sex attractant for queens. The results also suggest that this compound has another function as a trail marker used by males.

Bernardes, Rodrigo Cupertino; Barbosa, Wagner Faria; Martins, Gustavo Ferreira; Lima, Maria Augusta Pereira

2018-06-01

Large-scale pesticide application poses a major threat to bee biodiversity by causing a decline in bee populations that, in turn, compromises ecosystem maintenance and agricultural productivity. Biopesticides are considered an alternative to synthetic pesticides with a focus on reducing potential detrimental effects to beneficial organisms such as bees. The production of healthy queen stingless bees is essential for the survival and reproduction of hives, although it remains unknown whether biopesticides influence stingless bee reproduction. In the present study, we investigated the effects of the biopesticide azadirachtin on the survival, behavior, morphology, development, and reproduction of queens of the stingless bee Partamona helleri (Friese, 1900). The neonicotinoid imidacloprid was used as a toxic reference standard. Queens were orally exposed in vitro to a contaminated diet (containing azadirachtin and imidacloprid) during development. Azadirachtin resulted in reduced survival, similarly to imidacloprid, altered development time, caused deformations, and reduced the size of the queens' reproductive organs. All of these factors could potentially compromise colony survival. Results from the present study showed azadirachtin posed a toxicological hazard to P. helleri queens. Copyright © 2018 Elsevier Ltd.

Bushby, Philip; Woodruff, Kimberly; Shivley, Jake

2015-01-01

Simple Summary First initiated in 1995 to provide veterinary students with spay/neuter experience, the shelter program at the Mississippi State University College of Veterinary Medicine has grown to be comprehensive in nature incorporating spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Junior veterinary students spend five days in shelters; senior veterinary students spend 2-weeks visiting shelters in mobile veterinary units. The program has three primary components: spay/neuter, shelter medical days and Animals in Focus. Student gain significant hands-on experience and evaluations of the program by students are overwhelmingly positive. Abstract The shelter program at the Mississippi State University College of Veterinary Medicine provides veterinary students with extensive experience in shelter animal care including spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Students spend five days at shelters in the junior year of the curriculum and two weeks working on mobile veterinary units in their senior year. The program helps meet accreditation standards of the American Veterinary Medical Association’s Council on Education that require students to have hands-on experience and is in keeping with recommendations from the North American Veterinary Medical Education Consortium. The program responds, in part, to the challenge from the Pew Study on Future Directions for Veterinary Medicine that argued that veterinary students do not graduate with the level of knowledge and skills that is commensurate with the number of years of professional education.

Intraspecific variation in social organization is common, yet the underlying causes are rarely known. An exception is the fire ant Solenopsis invicta in which the existence of two distinct forms of social colony organization is under the control of the two variants of a pair of social chromosomes, SB and Sb. Colonies containing exclusively SB/SB workers accept only one single queen and she must be SB/SB. By contrast, when colonies contain more than 10% of SB/Sb workers, they accept several queens but only SB/Sb queens. The variants of the social chromosome are associated with several additional important phenotypic differences, including the size, fecundity and dispersal strategies of queens, aggressiveness of workers, and sperm count in males. However, little is known about whether social chromosome variants affect fitness in other life stages. Here, we perform experiments to determine whether differential selection occurs during development and in adult workers. We find evidence that the Sb variant of the social chromosome increases the likelihood of female brood to develop into queens and that adult SB/Sb workers, the workers that cull SB/SB queens, are overrepresented in comparison to SB/SB workers. This demonstrates that supergenes such as the social chromosome can have complex effects on phenotypes at various stages of development. © 2014 John Wiley & Sons Ltd.

Full Text Available The quality of college life means the overall satisfaction of students from the college life as a whole which is affected by different aspects of life based on the theory of generalization. The aim of this study is to evaluate the quality of college life among local and non-local students from non-state universities in Tehran. This study is developmental with respect to the aim and uses survey method for data gathering. The statistical population of the study are undergraduate students and 500 samples are chosen from the universities in the target population randomly and data are gathered using the questionnaire designed by the researcher the validity of the questionnaire has been verified based on the views of 5 experts and using some similar tested questionnaires as a model. The reliability has been estimated using Alpha Cronbach’s index by pre-test of 15 samples about 0.86. To data analyze SPSS software and statistical tests are used. The quality of the college life of students has been evaluated significantly lower than average and the quality of college life of non-local students is significantly higher than the quality of college life of local students. The low quality of college life shows that higher education policies on quality and national resources productivity have had low effectiveness. Dissatisfaction of students, as the key stakeholder of higher education system, from quality of college life could be a starting point to stray away from the higher education missions and philosophies. It is necessary that academic managers and leaders make serious decisions to promote the quality of college life. The higher education without the quality of college life, will be defeating the purpose.

2011-12-01

Full Text Available Three residential colleges located in Kuala Lumpur, Malaysia, were selected for energy performance analysis in regards to its implementation of bioclimatic design strategies. Specifically, passive design strategies on daylighting and natural ventilation were examined. In Malaysia, the residential college or hostel is a multi-residential building providing accommodation to university students. The three residential colleges in this study, namely C1, C2 and C3, were built in different years with different designs and forms, particularly with regards to enclosure and facade design, solar control devices, passive daylight concepts, and natural ventilation strategies. The building designs were carefully studied and an electric consumption analysis was carried out in each residential college. This study revealed that the wide-scale implementation of bioclimatic design strategies in college C2 help reduced the annual energy consumption. The building bioclimatic design features that are accountable to reduce energy consumption are the internal courtyard and balconies on each unit of floor area, as shown in C3.Results from this study highly recommend internal courtyard and balcony building combination for multi residential building design, especially in tropical urban regions.

A queen pheromone induces workers to kill sexual larvae in colonies of the red imported fire ant (Solenopsis invicta)

Science.gov (United States)

Klobuchar, Emily; Deslippe, Richard

2002-05-01

We conducted five bioassays to study how queens control the execution of sexual larvae by workers in colonies of the red imported fire ant, Solenopsis invicta. In each assay, subset colonies were made from many large polygyne colonies, and the 20 sexual larvae they contained were monitored over time. Sexual larvae mostly survived in queenless colonies, but were mostly killed in colonies with a single dealated queen, regardless of whether or not the queen was fertilized. The larvae were also killed when fresh corpses of queens were added to queenless colonies. Whereas acetone extracts of queens did not produce a significant increase in killings, extracts in buffered saline induced workers to execute most sexual larvae, indicating successful extraction of an execution pheromone. We identified the probable storage location of the chemical as the poison sac, and found both fresh (1 day) and old (21 day) extracts of poison sacs to be equally effective in inducing executions. The pheromone is stable at room temperature, perhaps because venom alkaloids also present in the extracts keep the pheromone from degrading. It is apparently either proteinaceous or associated with a proteinaceous molecule, a novel finding, as no queen pheromone of a proteinaceous nature has been previously demonstrated in ants.

Workers make the queens in melipona bees: identification of geraniol as a caste determining compound from labial glands of nurse bees.

Science.gov (United States)

Jarau, Stefan; van Veen, Johan W; Twele, Robert; Reichle, Christian; Gonzales, Eduardo Herrera; Aguilar, Ingrid; Francke, Wittko; Ayasse, Manfred

2010-06-01

Reproductive division of labor in advanced eusocial honey bees and stingless bees is based on the ability of totipotent female larvae to develop into either workers or queens. In nearly all species, caste is determined by larval nutrition. However, the mechanism that triggers queen development in Melipona bees is still unresolved. Several hypotheses have been proposed, ranging from the proximate (a genetic determination of caste development) to the ultimate (a model in which larvae have complete control over their own caste fate). Here, we showed that the addition of geraniol, the main compound in labial gland secretions of nurse workers, to the larval food significantly increases the number of larvae that develop into queens. Interestingly, the proportion of queens in treated brood exactly matched the value (25%) predicted by the two-locus, two-allele model of genetic queen determination, in which only females that are heterozygous at both loci are capable of developing into queens. We conclude that labial gland secretions, added to the food of some cells by nurse bees, trigger queen development, provided that the larvae are genetically predisposed towards this developmental pathway. In Melipona beecheii, geraniol acts as a primer pheromone representing the first caste determination substance identified to date.

Seasonal Dynamics in the Chemistry and Structure of the Fat Bodies of Bumblebee Queens.

Directory of Open Access Journals (Sweden)

Alena Votavová

Full Text Available Insects' fat bodies are responsible for nutrient storage and for a significant part of intermediary metabolism. Thus, it can be expected that the structure and content of the fat body will adaptively change, if an insect is going through different life stages. Bumblebee queens belong to such insects as they dramatically change their physiology several times over their lives in relation to their solitary overwintering, independent colony foundation stage, and during the colony life-cycle ending in the senescent stage. Here, we report on changes in the ultrastructure and lipid composition of the peripheral fat body of Bombus terrestris queens in relation to seasonal changes in the queens' activity. Six life stages are defined and evaluated in particular: pharate, callow, before and after hibernation, egg-laying, and senescence. Transmission electron microscopy revealed that the fat body contained two main cell types-adipocytes and oenocytes. Only adipocytes reveal important changes related to the life phase, and mostly the ration between inclusion and cytoplasm volume varies among particular stages. Both electron microscopy and chemical analyses of lipids highlighted seasonal variability in the quantity of the stored lipids, which peaked prior to hibernation. Triacylglycerols appeared to be the main energy source during hibernation, while the amount of glycogen before and after hibernation remained unchanged. In addition, we observed that the representation of some fatty acids within the triacylglycerols change during the queen's life. Last but not least, we show that fat body cell membranes do not undergo substantial changes concerning phospholipid composition in relation to overwintering. This finding supports the hypothesis that the cold-adaptation strategy of bumblebee queens is more likely to be based on polyol accumulation than on the restructuring of lipid membranes.

Institutional Capacities in E-learning and Problem Based Learning at Universities and University Colleges in Tanzania and Ghana

Ground-water resources of Kings and Queens Counties, Long Island, New York

Science.gov (United States)

Buxton, Herbert T.; Shernoff, Peter K.

1995-01-01

The aquifers beneath Kings and Queens Counties supplied an average of more than 120 Mgal/d (million gallons per day) for industrial and public water supply during 1904-47, but this pumping caused saltwater intrusion and a deterioration of water quality that led to the cessation of pumping for public supply in Kings County in 1947 and in western Queens County in 1974. Since the cessation of pumping in Kings and western Queens Counties, ground-water levels have recovered steadily, and the saltwater has partly dispersed and become diluted. In eastern Queens County, where pumpage for public supply averages 60 Mgal/d, all three major aquifers contain a large cone of depression. The saltwater-freshwater interface in the Jameco-Magothy aquifer already extends inland in southeastern Queens County and is moving toward this cone of depression. The pumping centers' proximity to the north shore also warrants monitoring for saltwater intrusion in the Flushing Bay area. Urbanization and development on western Long Island since before the tum of this century have caused significant changes in the ground-water budget (total inflow and outflow) and patterns of movement. Some of the major causes are: ( 1) intensive pumping for industrial and public supply; (2) paving of large land-surface areas; (3) installation of a vast network of combined (stonn and sanitary) sewers; (4) leakage from a water-supply-line network that carries more than 750 Mgal/d; and (5) burial of stream channels and extensive wetland areas near the shore.Elevated nitrate and chloride concentrations throughout the upper glacial (water-table) aquifer indicate widespread contamination from land surface. Localized contamination in the underlying Jameco-Magothy aquifer is attributed to downward migration in areas of hydraulic connection between aquifers where the Gardiners Clay is absent A channel eroded through the Raritan confining unit provides a pathway for migration of surface contaminants to the Lloyd aquifer

Divergent Streams: Race-Gender Achievement Gaps at Selective Colleges and Universities.

Massey, Douglas S; Probasco, Lierin

2010-03-01

In this paper, we extend previous research on racial performance gaps at 28 selective US colleges and universities by examining differences in grade achievement and graduate rates across race-gender categories. Using data from the National Longitudinal Survey of Freshmen, we show that black males, black females, and Hispanic males attain significantly lower grades than other race-gender groups, and that black males are 35% less likely to graduate on-time than other race-gender groups. Analyses consider an array of personal and institutional indicators of academic performance. Grades and graduation rates are improved by academic preparation (particularly high school GPA), scholarly effort, and, for graduation rates, membership in career-oriented or majority-white campus groups. Grade performance and graduation rates are undermined by a hostile racial climate on campus, family stress, and stereotype threat, all of which disproportionately affect minority students. We conclude with recommendations to college administrators for ways of selecting and supporting minority students to reduce differentials in academic achievement across race-gender groups.

Honey Bee Colonies Headed by Hyperpolyandrous Queens Have Improved Brood Rearing Efficiency and Lower Infestation Rates of Parasitic Varroa Mites.

Directory of Open Access Journals (Sweden)

Keith S Delaplane

Full Text Available A honey bee queen mates on wing with an average of 12 males and stores their sperm to produce progeny of mixed paternity. The degree of a queen's polyandry is positively associated with measures of her colony's fitness, and observed distributions of mating number are evolutionary optima balancing risks of mating flights against benefits to the colony. Effective mating numbers as high as 40 have been documented, begging the question of the upper bounds of this behavior that can be expected to confer colony benefit. In this study we used instrumental insemination to create three classes of queens with exaggerated range of polyandry--15, 30, or 60 drones. Colonies headed by queens inseminated with 30 or 60 drones produced more brood per bee and had a lower proportion of samples positive for Varroa destructor mites than colonies whose queens were inseminated with 15 drones, suggesting benefits of polyandry at rates higher than those normally obtaining in nature. Our results are consistent with two hypotheses that posit conditions that reward such high expressions of polyandry: (1 a queen may mate with many males in order to promote beneficial non-additive genetic interactions among subfamilies, and (2 a queen may mate with many males in order to capture a large number of rare alleles that regulate resistance to pathogens and parasites in a breeding population. Our results are unique for identifying the highest levels of polyandry yet detected that confer colony-level benefit and for showing a benefit of polyandry in particular toward the parasitic mite V. destructor.

Lorant, Vincent; Nicaise, Pablo; Soto, Victoria Eugenia; d'Hoore, William

2013-06-28

One young adult in two has entered university education in Western countries. Many of these young students will be exposed, during this transitional period, to substantial changes in living arrangements, socialisation groups, and social activities. This kind of transition is often associated with risky behaviour such as excessive alcohol consumption. So far, however, there is little evidence about the social determinants of alcohol consumption among college students. We set out to explore how college environmental factors shape college students' drinking behaviour. In May 2010 a web questionnaire was sent to all bachelor and master students registered with an important Belgian university; 7,015 students participated (participation = 39%). The survey looked at drinking behaviour, social involvement, college environmental factors, drinking norms, and positive drinking consequences. On average each student had 1.7 drinks a day and 2.8 episodes of abusive drinking a month. We found that the more a student was exposed to college environmental factors, the greater the risk of heavy, frequent, and abusive drinking. Alcohol consumption increased for students living on campus, living in a dormitory with a higher number of room-mates, and having been in the University for a long spell. Most such environmental factors were explained by social involvement, such as participation to the student folklore, pre-partying, and normative expectations. Educational and college authorities need to acknowledge universities' responsibility in relation to their students' drinking behaviour and to commit themselves to support an environment of responsible drinking.

Queen Christina’s esoteric interests as a background to her Platonic Academies

Directory of Open Access Journals (Sweden)

Susanna Åkerman

2008-01-01

Full Text Available In 1681 the blind quietist, Francois Malaval, stated that Queen Christina of Sweden late in life had ‘given up’ [Hermes] Trismegistos and the Platonists, in favour of the Church fathers. The statement does not explain what role the Church fathers were to play in her last years, but it does show that Christina really had been interested in the rather elitist and esoteric doctrine of Hermetic Platonic Christianity. In this article the author looks at her library to show the depth of this Hermetic involvement. Her interest serves as a background to her life as ex-queen in Italy after her famous abdication from the Swedish throne in 1654, when she was 27 years old.

Unseen disadvantage: how American universities' focus on independence undermines the academic performance of first-generation college students.

Stephens, Nicole M; Fryberg, Stephanie A; Markus, Hazel Rose; Johnson, Camille S; Covarrubias, Rebecca

2012-06-01

American universities increasingly admit first-generation college students whose parents do not have 4-year degrees. Once admitted, these students tend to struggle academically, compared with continuing-generation students--students who have at least 1 parent with a 4-year degree. We propose a cultural mismatch theory that identifies 1 important source of this social class achievement gap. Four studies test the hypothesis that first-generation students underperform because interdependent norms from their mostly working-class backgrounds constitute a mismatch with middle-class independent norms prevalent in universities. First, assessing university cultural norms, surveys of university administrators revealed that American universities focus primarily on norms of independence. Second, identifying the hypothesized cultural mismatch, a longitudinal survey revealed that universities' focus on independence does not match first-generation students' relatively interdependent motives for attending college and that this cultural mismatch is associated with lower grades. Finally, 2 experiments at both private and public universities created a match or mismatch for first-generation students and examined the performance consequences. Together these studies revealed that representing the university culture in terms of independence (i.e., paving one's own paths) rendered academic tasks difficult and, thereby, undermined first-generation students' performance. Conversely, representing the university culture in terms of interdependence (i.e., being part of a community) reduced this sense of difficulty and eliminated the performance gap without adverse consequences for continuing-generation students. These studies address the urgent need to recognize cultural obstacles that contribute to the social class achievement gap and to develop interventions to address them. 2012 APA, all rights reserved

Establishing Good Laboratory Practice at Small Colleges and Universities

2017-05-01

Full Text Available Good Laboratory Practice (GLP and Standard Operating Procedures (SOPs provide guidelines for proper operation of equipment, maintenance and sanitation, reporting structures, and related activities. These practices are routinely employed at large academic and research-based institutions. However, they are often overlooked or omitted at smaller colleges and universities where staff and resources are limited. Incorrect assumptions and presumed responsibilities can lead to safety hazards, damage to equipment, loss of infrastructure, and confusion regarding operations and oversight. This report addresses the development of the “who, what, when, how, and where” policies and SOPs that constitute GLP. Once established and utilized by all departmental members, these structures ensure that academic and research-related activities are conducted safely and efficiently.

Full Text Available Over the past years educational institutions have been investing increasingly substantial amount of money in integrating Information Technology (IT in the course of educational services delivery with the objective of improving operational efficiency and competitive advantage. The important role IT plays in educational institutions is unquestionable. It is regarded as a critical factor of innovation for growth and survival. The evaluation of the impact of this innovation in the educational system drives the researcher to undertake a study on Operational Efficiency of Information Technology and Organizational Performance of State Universities and Colleges (SUCs of Region VI, Philippines. Descriptive method was used utilizing a validated survey questionnaire which also involved the desk and field research conducted by a panel of two field researchers including the researcher himself covering selected SUCs of Region VI. Deans or department heads and faculty of the different colleges or departments, administrative and academic officials constitute the respondents of the study. Stratified proportional random sampling and purposive sampling were used in the study. Results of the study were viewed and analyzed using the Mean and the Pearson r Correlation Coefficient. Findings revealed that the operational efficiency of the SUCs of Region VI is moderately efficient while the majority of colleges/universities are performing moderately efficient. The study also revealed that the organizational performance of SUCs and the majority of colleges/universities are performing very satisfactory. Likewise, the findings also showed a significant relationship between the operational efficiency of information technology and organizational performance of SUCs. However, a significant relationship between operational efficiency and organizational performance of SUCs in instruction does not exist while a significant relationship exists in research, extension and

Ruan, Bin; Mok, Magdalena Mo Ching; Edginton, Christopher R; Chin, Ming Kai

2012-01-01

This article describes the development and validation of the Core Competencies Scale (CCS) using Bok's (2006) competency framework for undergraduate education. The framework included: communication, critical thinking, character development, citizenship, diversity, global understanding, widening of interest, and career and vocational development. The sample comprised 70 college and university students. Results of analysis using Rasch rating scale modelling showed that there was strong empirical evidence on the validity of the measures in contents, structure, interpretation, generalizability, and response options of the CCS scale. The implication of having developed Rasch-based valid and dependable measures in this study for gauging the value added of college and university education to their students is that the feedback generated from CCS will enable evidence-based decision and policy making to be implemented and strategized. Further, program effectiveness can be measured and thus accountability on the achievement of the program objectives.

Honeybee Venom Proteome Profile of Queens and Winter Bees as Determined by a Mass Spectrometric Approach

Science.gov (United States)

Danneels, Ellen L.; Van Vaerenbergh, Matthias; Debyser, Griet; Devreese, Bart; de Graaf, Dirk C.

2015-01-01

Venoms of invertebrates contain an enormous diversity of proteins, peptides, and other classes of substances. Insect venoms are characterized by a large interspecific variation resulting in extended lists of venom compounds. The venom composition of several hymenopterans also shows different intraspecific variation. For instance, venom from different honeybee castes, more specifically queens and workers, shows quantitative and qualitative variation, while the environment, like seasonal changes, also proves to be an important factor. The present study aimed at an in-depth analysis of the intraspecific variation in the honeybee venom proteome. In summer workers, the recent list of venom proteins resulted from merging combinatorial peptide ligand library sample pretreatment and targeted tandem mass spectrometry realized with a Fourier transform ion cyclotron resonance mass spectrometer (FT-ICR MS/MS). Now, the same technique was used to determine the venom proteome of queens and winter bees, enabling us to compare it with that of summer bees. In total, 34 putative venom toxins were found, of which two were never described in honeybee venoms before. Venom from winter workers did not contain toxins that were not present in queens or summer workers, while winter worker venom lacked the allergen Api m 12, also known as vitellogenin. Venom from queen bees, on the other hand, was lacking six of the 34 venom toxins compared to worker bees, while it contained two new venom toxins, in particularly serine proteinase stubble and antithrombin-III. Although people are hardly stung by honeybees during winter or by queen bees, these newly identified toxins should be taken into account in the characterization of a putative allergic response against Apis mellifera stings.

Chemical profiles of two pheromone glands are differentially regulated by distinct mating factors in honey bee queens (Apis mellifera L..

Directory of Open Access Journals (Sweden)

Elina L Niño

Full Text Available Pheromones mediate social interactions among individuals in a wide variety of species, from yeast to mammals. In social insects such as honey bees, pheromone communication systems can be extraordinarily complex and serve to coordinate behaviors among many individuals. One of the primary mediators of social behavior and organization in honey bee colonies is queen pheromone, which is produced by multiple glands. The types and quantities of chemicals produced differ significantly between virgin and mated queens, and recent studies have suggested that, in newly mated queens, insemination volume or quantity can affect pheromone production. Here, we examine the long-term impact of different factors involved during queen insemination on the chemical composition of the mandibular and Dufour's glands, two of the major sources of queen pheromone. Our results demonstrate that carbon dioxide (an anesthetic used in instrumental insemination, physical manipulation of genital tract (presumably mimicking the act of copulation, insemination substance (saline vs. semen, and insemination volume (1 vs. 8 µl all have long-term effects on mandibular gland chemical profiles. In contrast, Dufour's gland chemical profiles were changed only upon insemination and were not influenced by exposure to carbon dioxide, manipulation, insemination substance or volume. These results suggest that the chemical contents of these two glands are regulated by different neuro-physiological mechanisms. Furthermore, workers responded differently to the different mandibular gland extracts in a choice assay. Although these studies must be validated in naturally mated queens of varying mating quality, our results suggest that while the chemical composition of Dufour's gland is associated with mating status, that of the mandibular glands is associated with both mating status and insemination success. Thus, the queen appears to be signaling both status and reproductive quality to the workers

Influence of toxic bait type and starvation on worker and queen mortality in laboratory colonies of Argentine ant (Hymenoptera: Formicidae).

Mathieson, Melissa; Toft, Richard; Lester, Philip J

2012-08-01

The efficacy of toxic baits should be judged by their ability to kill entire ant colonies, including the colony queen or queens. We studied the efficacy of four toxic baits to the Argentine ant, Linepithema humile (Mayr) (Hymenoptera: Formicidae). These baits were Xstinguish that has the toxicant fipronil, Exterm-an-Ant that contains both boric acid and sodium borate, and Advion ant gel and Advion ant bait arena that both have indoxacarb. Experimental nests contained 300 workers and 10 queen ants that were starved for either 24 or 48 h before toxic bait exposure. The efficacy of the toxic baits was strongly influenced by starvation. In no treatment with 24-h starvation did we observe 100% worker death. After 24-h starvation three of the baits did not result in any queen deaths, with only Exterm-an-Ant producing an average of 25% mortality. In contrast, 100% queen and worker mortality was observed in colonies starved for 48 h and given Xstinguish or Exterm-an-Ant. The baits Advion ant gel and Advion ant bait arena were not effective against Argentine ants in these trials, resulting in ants are likely to be starved. Our results suggest queen mortality must be assessed in tests for toxic bait efficacy. Our data indicate that of these four baits, Xstinguish and Exterm-an-Ant are the best options for control of Argentine ants in New Zealand.

Morphometric study of newly emerged unmated queens of honey bee Apis mellifera L. in Ismailia Governorate, Egypt

2013-06-01

Full Text Available Recently, morphometric analysis is being a very good tool for identification of honey bee races and characterization of genetic materials. This fact has motivated the present work to investigate the effects of two grafting methods, three types of artificial queen wax cups and four periods of queen rearing on some morphological characters of newly emerged queens. The developed technique used in the present study depends on the integration between Scanner unit and Photoshop program, called Scan Photo Method (SPM. The measurements of 23 morphological characteristics of reared queens were estimated by using SPM. Results indicated significant differences between periods in the measurements of the studied characteristics on forewing such as cubital index, distance C, distance D, radial field, inner wing length, inner wing width, dumb bell index, distance I, II, III and IV, except cubital A and cubital B. Regarding the effects of cup types and grafting methods, data also revealed significant differences in all measurements of studied characteristics, except tibial length, hind wing length, cubital B, radial field and distance IV. Further works in this area were recommended to find out a relation between some morphometric characters and important of some quantitative characters.

A comparison of honeybee (Apis mellifera) queen, worker and drone larvae by RNA-Seq.

He, Xu-Jiang; Jiang, Wu-Jun; Zhou, Mi; Barron, Andrew B; Zeng, Zhi-Jiang

2017-11-06

Honeybees (Apis mellifera) have haplodiploid sex determination: males develop from unfertilized eggs and females develop from fertilized ones. The differences in larval food also determine the development of females. Here we compared the total somatic gene expression profiles of 2-day and 4-day-old drone, queen and worker larvae by RNA-Seq. The results from a co-expression network analysis on all expressed genes showed that 2-day-old drone and worker larvae were closer in gene expression profiles than 2-day-old queen larvae. This indicated that for young larvae (2-day-old) environmental factors such as larval diet have a greater effect on gene expression profiles than ploidy or sex determination. Drones had the most distinct gene expression profiles at the 4-day larval stage, suggesting that haploidy, or sex dramatically affects the gene expression of honeybee larvae. Drone larvae showed fewer differences in gene expression profiles at the 2-day and 4-day time points than the worker and queen larval comparisons (598 against 1190 and 1181), suggesting a different pattern of gene expression regulation during the larval development of haploid males compared to diploid females. This study indicates that early in development the queen caste has the most distinct gene expression profile, perhaps reflecting the very rapid growth and morphological specialization of this caste compared to workers and drones. Later in development the haploid male drones have the most distinct gene expression profile, perhaps reflecting the influence of ploidy or sex determination on gene expression. © 2017 Institute of Zoology, Chinese Academy of Sciences.

The success of an ant colony depends on the simultaneous presence of reproducing queens and nonreproducing workers in a ratio that will maximize colony growth and reproduction. Despite its presumably crucial role, queen–worker caste ratios (the ratio of adult queens to workers) and the factors...... affecting this variable remain scarcely studied. Maintaining polygynous pharaoh ant (Monomorium pharaonis) colonies in the laboratory has provided us with the opportunity to experimentally manipulate colony size, one of the key factors that can be expected to affect colony level queen–worker caste ratios...... species with budding colonies may adaptively adjust caste ratios to ensure rapid growth....

Morphometric Identification of Queens, Workers and Intermediates in In Vitro Reared Honey Bees (Apis mellifera).

2015-01-01

In vitro rearing is an important and useful tool for honey bee (Apis mellifera L.) studies. However, it often results in intercastes between queens and workers, which are normally are not seen in hive-reared bees, except when larvae older than three days are grafted for queen rearing. Morphological classification (queen versus worker or intercastes) of bees produced by this method can be subjective and generally depends on size differences. Here, we propose an alternative method for caste classification of female honey bees reared in vitro, based on weight at emergence, ovariole number, spermatheca size and size and shape, and features of the head, mandible and basitarsus. Morphological measurements were made with both traditional morphometric and geometric morphometrics techniques. The classifications were performed by principal component analysis, using naturally developed queens and workers as controls. First, the analysis included all the characters. Subsequently, a new analysis was made without the information about ovariole number and spermatheca size. Geometric morphometrics was less dependent on ovariole number and spermatheca information for caste and intercaste identification. This is useful, since acquiring information concerning these reproductive structures requires time-consuming dissection and they are not accessible when abdomens have been removed for molecular assays or in dried specimens. Additionally, geometric morphometrics divided intercastes into more discrete phenotype subsets. We conclude that morphometric geometrics are superior to traditional morphometrics techniques for identification and classification of honey bee castes and intermediates.

DNA extraction from wings as a suitable approach for queen bees genotyping

Directory of Open Access Journals (Sweden)

Elena Facchini

2018-06-01

Full Text Available In livestock, genomics has been used since a decade in combination with phenotypic information for the estimation of breeding values. In honey bees (Apis mellifera, the advantage for including genomics in selective breeding programmes is represented by the possibility to reduce the generation interval and increase the accuracies of estimated breeding values resulting in higher genetic gain (Brascamp et al., 2018. The limit for this application is DNA extraction. Extraction methods for small animals such as insects often rely upon destructive approaches. The challenge is to develop tissue sampling methods that permit the survival of the animal while providing adequate quality DNA for genotyping. Along with previous reports of DNA extraction from several matrices, this study aims to contribute in developing suitable methodologies for genotyping honey bees queens using DNA extracted from wing cuttings (Chaline et al., 2004; Gregory and Rinderer, 2004; Gould et al., 2011. The clipping of the queen wings in beekeeping is a common practice and it ensures the survival and normal activities of the animal (Forster, 1971. A total of 57 queens with known pedigree were enrolled for this study. Wings from each queen were cut and stored at -20°C until processed (Fig. 1. Extractions were carried out using a modified protocol provided by Qiagen (DNeasy® Blood & Tissue. The modification consists in an initial incubation of the samples with proteinase K for 20 minutes, further steps are carried out following the manufacturer’s instructions. To test the suitability of the extracted DNA for genotyping, PCR was performed on Esterase FE4 like gene. Although quantification with NanoDrop™ resulted in <20 ng/μL of DNA in solution, the extracted material was sufficient for PCR amplification of candidate genes for sequencing and genotyping. Our results show that it is possible to extract DNA from wings’ cuttings permitting to implement genomic approaches in honey

Impact of chronic neonicotinoid exposure on honeybee colony performance and queen supersedure.

Full Text Available BACKGROUND: Honeybees provide economically and ecologically vital pollination services to crops and wild plants. During the last decade elevated colony losses have been documented in Europe and North America. Despite growing consensus on the involvement of multiple causal factors, the underlying interactions impacting on honeybee health and colony failure are not fully resolved. Parasites and pathogens are among the main candidates, but sublethal exposure to widespread agricultural pesticides may also affect bees. METHODOLOGY/PRINCIPAL FINDINGS: To investigate effects of sublethal dietary neonicotinoid exposure on honeybee colony performance, a fully crossed experimental design was implemented using 24 colonies, including sister-queens from two different strains, and experimental in-hive pollen feeding with or without environmentally relevant concentrations of thiamethoxam and clothianidin. Honeybee colonies chronically exposed to both neonicotinoids over two brood cycles exhibited decreased performance in the short-term resulting in declining numbers of adult bees (-28% and brood (-13%, as well as a reduction in honey production (-29% and pollen collections (-19%, but colonies recovered in the medium-term and overwintered successfully. However, significantly decelerated growth of neonicotinoid-exposed colonies during the following spring was associated with queen failure, revealing previously undocumented long-term impacts of neonicotinoids: queen supersedure was observed for 60% of the neonicotinoid-exposed colonies within a one year period, but not for control colonies. Linked to this, neonicotinoid exposure was significantly associated with a reduced propensity to swarm during the next spring. Both short-term and long-term effects of neonicotinoids on colony performance were significantly influenced by the honeybees' genetic background. CONCLUSIONS/SIGNIFICANCE: Sublethal neonicotinoid exposure did not provoke increased winter losses. Yet

This article is a transcription of an interview with William N. Schoenfeld made in 1990. William N. Schoenfeld (1915-1996) is one of the outstanding contributors to the initial stages of the experimental analysis of behavior. After graduating from Columbia University, Schoenfeld wrote, in collaboration with Fred S. Keller, what was at that time the most significant book introducing, and updating, the seminal contributions of B. F. Skinner and other behavioral psychologists: Principles of Psychology (1950). Schoenfeld was also instrumental in the design of a psychology course at Columbia University based on the integration of theory and laboratory work, as well as in the foundation of the Journal of the Experimental Analysis of Behavior in 1958. In 1968 Schoenfeld moved to the Queens College of the City University of New York, where he developed a doctoral program based in the research of stimulus schedules (T system), the analysis of conceptual and theoretical problems in operant conditioning, and the study of respondent and operant interactions under pharmacological agents. After his retirement from Queens College, Schoenfeld taught at Bar-Ilan University and the Hebrew University in Israel. The interview forms part of a research project on the experimental analysis of scientific behavior (Ribes, 1994), which also included two other distinguished and original contributors of the experimental analysis of behavior, B. F. Skinner and R. J. Herrnstein.

Fantasy under Duress: Connie Scozzaro’s Contrapposto Action Queen

Directory of Open Access Journals (Sweden)

Edward Luker

2017-01-01

Full Text Available This article explores how Connie Scozzaro’s 'Contrapposto Action Queen (2013' repeatedly takes up two mystifications of femininity from classical mythology, Venus and Lamia, so as to subject them to critique. It takes the images of Venus and Lamia from the writing of two poets, Charles Algernon Swinburne and John Keats. These examples are shown to be epitomes of male poetic fantasy. Within Scozzaro’s collection these fantasies are dissected, undermined, or taken apart through exaggeration, ironization, and the use of tone. The book makes explicit that within patriarchal society, male fantasies are part of a social condition of gendered violence. Contra Brandon Brown’s argument that 'Contrapposto Action Queen' articulates the dialectic of the possible and the actual, this article articulates that for Scozzaro the possible is always conditioned by fantasy. It finishes by looking at Theodor Adorno’s essay ‘Lyric Poetry and Society’. Where Adorno states the lyric subject manifests itself with masculine ‘unrestrained individuation’, this fails to grasp how the lyric poem can utilize strategies of concealment to stress the consequences of the lyric subject’s gendering.

Full Text Available Male circumcision (MC has been shown to reduce the risk of female to male transmission of HIV. The goal of this survey was to explore MC's acceptability and the factors associated with MC among college students in medical universities in western China.A cross-sectional study was carried out in three provinces in western China (Guangxi, Chongqing and Xinjiang to assess the acceptability of MC as well as to discover factors associated with the acceptability among college students in medical universities. A total of 1,790 uncircumcised male students from three medical universities were enrolled in this study. In addition, 150 students who had undergone MC were also enrolled in the survey, and they participated in in-depth interviews.Of all the uncircumcised participants (n = 1,790, 55.2% (n = 988 were willing to accept MC. Among those who accepted MC, 67.3% thought that MC could improve their sexual partners' hygiene, 46.3% believed that HIV and sexually transmitted diseases (STDs could be partially prevented by MC. The multivariable logistic regression indicates that MC's acceptability was associated with three factors: the redundant foreskin (OR = 10.171, 95% CI = 7.629-13.559, knowing the hazard of having a redundant foreskin (OR = 1.597, 95% CI = 1.097-2.323, and enhancing sexual pleasure (OR = 1.628, 95% CI = 1.312-2.021. The in-depth interviews for subjects who had undergone MC showed that the major reason for having MC was the redundant foreskin (87.3%, followed by the benefits and the fewer complications of having MC done. In addition, most of these participants (65.3% said that the MC could enhance sexual satisfaction.MC's acceptance among college students in medical universities is higher than it is among other populations in western China. An implementation of an MC programme among this population is feasible in the future.

Virgin queen attraction toward males in honey bees

Although the honeybee is a crucial agricultural agent and a prominent scientific model organism, crucial aspects of its reproductive behaviour are still unknown. During the mating season, honeybee males, the drones, gather in congregations 10?40?m above ground. Converging evidence suggests that drones emit a pheromone that can attract other drones, thereby increasing the size of the congregation. Virgin queens join the vicinity of the congregation after it has formed, and mate with as many as...

Full Text Available The main aim of present study was to examine the quality of college life (QCL based on the model developed by Sirgy et aI., (20] 0. The research design was correlational and the sample was comprises of 400 students from three universities including Tehran, Allameh and Kurdestan, which the respondents were selected using random sampling method. Quality of college life measurement was included three main subjects about college life as satisfaction with academic aspect, social aspect and facilities and services. In order to analysis the data structural equation modeling (SEM were employed. Findings indicated that the satisfaction with services and facilities has significant effect on satisfaction with academic and social aspects of college life. Moreover findings revealed that satisfaction with quality of college life has significant effect on satisfaction with overall life among students. Results indicated that the satisfaction with academic aspect and facilities and services among Tehran's university students is higher than Kurdestan's university students. Based on present findings the quality of universities may receive more attentions by higher education system especially in low income provinces such as Kurdestan. Lack of facilities resulted in decreasing the quality of academic aspect, social aspect and quality of college life. Low satisfaction with college life is leading to decreasing the overall life satisfaction which resulted in issues such as depression, frustration and anxiety among students.

Effect of Different Substrates on the Acceptance of Grafted Larvae in Commercial Honey Bee (Apis Mellifera Queen Rearing

Directory of Open Access Journals (Sweden)

Contreras-Martinez Celia A.

2017-12-01

Full Text Available The need for the increased production of honey bee (Apis mellifera queens has led beekeepers to use different substrates in artificial queen cups where larvae destined to become queens are deposited (grafting. However, not enough scientific evidence exists that indicates that this practice is useful and what substance offers the best results. This study was conducted to determine with the Doolittle queen rearing method the acceptance rate of larvae deposited on different substrates during grafting and to determine if the sugar content and pH of the substrates used affect the acceptance of larvae in cell builder colonies. The evaluated substrates were coconut water, apple nectar, royal jelly, cola soda and distilled water, plus control (without substrate. Grafted larvae of the six treatments were introduced into cell builder colonies and their acceptance verified after 72 h. Apple nectar provided the highest rate of larvae acceptance with 81.06%, followed by cola soda with 62.93%, coconut water with 60.90%, royal jelly with 57.82% and distilled water with 58.99%. The larvae acceptance rates of all substrates were significantly higher than the control, which had an acceptance rate of 47.04%. No significant relationship was found between the sugar content of the substrates and larvae acceptance. However, although not significant, a high negative correlation was found between the substrate pH and the number of accepted larvae (Rho = - 0.90, p = 0.07. These results suggest that the use of liquid acidic substrates during larvae grafting, in particular apple nectar, may increase the production of honey bee queens.

According to the classic life history theory, selection for longevity depends on age-dependant extrinsic mortality and fecundity. In social insects, the common life history trade-off between fecundity and longevity appears to be reversed, as the most fecund individual, the queen, often exceeds workers in lifespan several fold. But does fecundity directly affect intrinsic mortality also in social insect workers? And what is the effect of task on worker mortality? Here, we studied how social environment and behavioral caste affect intrinsic mortality of ant workers. We compared worker survival between queenless and queenright Temnothorax longispinosus nests and demonstrate that workers survive longer under the queens' absence. Temnothorax ant workers fight over reproduction when the queen is absent and dominant workers lay eggs. Worker fertility might therefore increase lifespan, possibly due to a positive physiological link between fecundity and longevity, or better care for fertile workers. In social insects, division of labor among workers is age-dependant with young workers caring for the brood and old ones going out to forage. We therefore expected nurses to survive longer than foragers, which is what we found. Surprisingly, inactive inside workers showed a lower survival than nurses but comparable to that of foragers. The reduced longevity of inactive workers could be due to them being older than the nurses, or due to a positive effect of activity on lifespan. Overall, our study points to behavioral caste-dependent intrinsic mortality rates and a positive association between fertility and longevity not only in queens but also in ant workers.

To assess preliminary results of the Expanded Syringe Access Demonstration Program (ESAP) in New York City. Temporal trends of pharmacy use among injection drug users (IDUs) in Brooklyn and Queens were analyzed from December 2000 through December 2001. Brooklyn and Queens, New York City. PARTIPANTS: IDUs. Attempts to purchase syringes from pharmacies and success in doing so. Of the 1,072 IDUs interviewed from December 2000 through December 2001, the majority were daily heroin injectors, but there was also substantial speedball and cocaine injection. There was a clear increase over time in both the percentage of subjects who attempted to purchase syringes in pharmacies and in the percentage who successfully purchased syringes. Among IDUs interviewed 4 or more months after ESAP began, large majorities of those who attempted to purchase syringes were successful in doing so. No differences in use of ESAP by IDUs were identified in Brooklyn versus Queens: 27% of IDUs interviewed in Queens reported that they had attempted to purchase syringes in pharmacies versus 28% in Brooklyn. Persons who reported injecting on a daily or more frequent basis were more likely to have attempted pharmacy purchases than persons who reported injecting less frequently, 32% versus 21%. The ESAP program has led to an increase in the use of pharmacies as sources of sterile injection equipment among IDUs in New York City. The extent to which pharmacies become an important source of sterile injection equipment and the effect of legal pharmacy sales on risk behaviors for human immunodeficiency virus (HIV) infection remain to be determined.

Cellulolytic Protist Numbers Rise and Fall Dramatically in Termite Queens and Kings during Colony Foundation

Among the best-known examples of mutualistic symbioses is that between lower termites and the cellulolytic flagellate protists in their hindguts. Although the symbiosis in worker termites has attracted much attention, there have been only a few studies of protists in other castes. We have performed the first examination of protist population dynamics in queens and kings during termite colony foundation. Protist numbers, as well as measurements of hindgut and reproductive tissue sizes, were undertaken at five time points over 400 days in incipient colonies of Reticulitermes speratus, as well as in other castes of mature colonies of this species. We found that protist numbers increased dramatically in both queens and kings during the first 50 days of colony foundation but began to decrease by day 100, eventually disappearing by day 400. Hindgut width followed a pattern similar to that of protist numbers, while ovary and testis widths increased significantly only at day 400. Kings were found to contain higher numbers of protists than queens in incipient colonies, which may be linked to higher levels of nutrient transfer from kings to queens than vice versa, as is known in some other termite species. Protists were found to be abundant in soldiers from mature colonies but absent in neotenics. This probably reflects feeding of soldiers by workers via proctodeal trophallaxis and of reproductives via stomodeal trophallaxis. The results reveal the dynamic nature of protist numbers during colony foundation and highlight the trade-offs that exist between reproduction and parental care during this critical phase of the termite life cycle.

The Red Queen model of recombination hot-spot evolution: a theoretical investigation.

Science.gov (United States)

Latrille, Thibault; Duret, Laurent; Lartillot, Nicolas

2017-12-19

In humans and many other species, recombination events cluster in narrow and short-lived hot spots distributed across the genome, whose location is determined by the Zn-finger protein PRDM9. To explain these fast evolutionary dynamics, an intra-genomic Red Queen model has been proposed, based on the interplay between two antagonistic forces: biased gene conversion, mediated by double-strand breaks, resulting in hot-spot extinction, followed by positive selection favouring new PRDM9 alleles recognizing new sequence motifs. Thus far, however, this Red Queen model has not been formalized as a quantitative population-genetic model, fully accounting for the intricate interplay between biased gene conversion, mutation, selection, demography and genetic diversity at the PRDM9 locus. Here, we explore the population genetics of the Red Queen model of recombination. A Wright-Fisher simulator was implemented, allowing exploration of the behaviour of the model (mean equilibrium recombination rate, diversity at the PRDM9 locus or turnover rate) as a function of the parameters (effective population size, mutation and erosion rates). In a second step, analytical results based on self-consistent mean-field approximations were derived, reproducing the scaling relations observed in the simulations. Empirical fit of the model to current data from the mouse suggests both a high mutation rate at PRDM9 and strong biased gene conversion on its targets.This article is part of the themed issue 'Evolutionary causes and consequences of recombination rate variation in sexual organisms'. © 2017 The Authors.

The Queen's Hospital opened in 1917 to care for soldiers receiving facial injuries in Western Front trenches, usually as a result of a gunshot wound. Some 8000 patients were treated by the medical teams of the UK, the Dominions and the USA. The wartime records were removed by their respective sections in 1921, but Queen Mary's Hospital has recently reacquired those of the New Zealand section, rescued from imminent destruction by Professor A.D. Macalister, late Dean of the Dental School at Dunedin, and kindly donated by him. There are 282 sets of case-notes containing typescript summaries, clinical photographs and radiographs, drawings, 77 watercolor paintings and a life-size wax model of head and upper torso illustrating some of the surgical techniques. The archive is a fine example of medical illustration 75 years ago, and provides invaluable detail on the plastic surgery and dental reconstructive methods that were developed at Sidcup.

Natural Larval Diet Differently Influences the Pattern of Developmental Changes in DNA 5-Methylcytosine Levels in Apis mellifera Queens as Compared with Workers and Drones.

Strachecka, A; Olszewski, K; Bajda, M; Demetraki-Paleolog, J

2015-08-01

The principal mechanism of gene activation/silencing is DNA 5-methylcytosine methylation. This study was aimed at determining global DNA methylation levels in larvae, prepupae, pupae, and 1-day-old adults of Apis mellifera queens, workers and drones. The Imprint Methylated DNA Quantification Kit MDQ1 was used. Percentages of DNA 5-methylcytosine were low and relatively similar in the larvae of all the castes until 4th day of larval development (3-5%). However, they were higher in the drone and worker larvae than in the queen larvae. Generally, the developmental patterns of changes in the DNA methylation levels were different in the queens in comparison with the drones and workers. While methylation increased in the queens, it decreased in the drones and workers. Methylated DNA methylcytosine percentages and weights in the queen prepupae (15%, 9.18 ng) and pupae (21%, 10.74 ng) were, respectively, three and four times higher than in the worker/drone brood of the same age (2.5-4%, 0.03-0.07 ng). Only in the queens, after a substantial increase, did DNA methylation decrease almost twice between the pupal stage and queen emergence (from 21% and 10.74 ng to 12% and 6.78 ng). This finding seems very interesting, particularly for experimental gerontology.

Weaver ants (Oecophylla longinoda Latreille) are used commercially to control pest insects and for protein production. In this respect fast colony growth is desirable for managed colonies. Transplantation of non-nestmate pupae to incipient colonies has been shown to boost colony growth. Our...... of 300 pupae increased total colony size more than 10-fold whereas 100 pupae increased the size 5.6 fold, compared to control. This increase was due not only to the individuals added in the form of pupae but also to an increased per capita brood production by the resident queen, triggered by the adopted...... objectives were to find the maximum number of pupae a founding queen can handle, and to measure the associated colony growth. Secondly, we tested if transplantation of pupae led to production of larger nanitic workers (defined as unusually small worker ants produced by founding queens in their first batch...

Mating frequencies of honey bee queens (Apis mellifera L.) in a population of feral colonies in the Northeastern United States.

Tarpy, David R; Delaney, Deborah A; Seeley, Thomas D

2015-01-01

Across their introduced range in North America, populations of feral honey bee (Apis mellifera L.) colonies have supposedly declined in recent decades as a result of exotic parasites, most notably the ectoparasitic mite Varroa destructor. Nonetheless, recent studies have documented several wild populations of colonies that have persisted. The extreme polyandry of honey bee queens-and the increased intracolony genetic diversity it confers-has been attributed, in part, to improved disease resistance and may be a factor in the survival of these populations of feral colonies. We estimated the mating frequencies of queens in feral colonies in the Arnot Forest in New York State to determine if the level of polyandry of these queens is especially high and so might contribute to their survival success. We genotyped the worker offspring from 10 feral colonies in the Arnot Forest of upstate New York, as well as those from 20 managed colonies closest to this forest. We found no significant differences in mean mating frequency between the feral and managed queens, suggesting that queens in the remote, low-density population of colonies in the Arnot Forest are neither mate-limited nor adapted to mate at an especially high frequency. These findings support the hypothesis that the hyperpolyandry of honey bees has been shaped on an evolutionary timescale rather than on an ecological one.

The extreme polyandry of honey bee queens-and the increased intracolony genetic diversity it confers-has been attributed, in part, to improved disease resistance and may be a factor in the survival of these populations of feral colonies. We estimated the mating frequencies of queens in feral colonies in the Arnot Forest in New York State to determine if the level of polyandry of these queens is especially high and so might contribute to their survival success. We genotyped the worker offspring from 10 feral colonies in the Arnot Forest of upstate New York, as well as those from 20 managed colonies closest to this forest. We found no significant differences in mean mating frequency between the feral and managed queens, suggesting that queens in the remote, low-density population of colonies in the Arnot Forest are neither mate-limited nor adapted to mate at an especially high frequency. These findings support the hypothesis that the hyperpolyandry of honey bees has been shaped on an evolutionary timescale rather than on an ecological one.

Workers and alate queens of Solenopsis geminata share qualitatively similar but quantitatively different venom alkaloid chemistry

Full Text Available Solenopsis geminata group (Hymenoptera: Formicidae encompasses ant species commonly called fire ants because of their painful sting. The many physiological effects of the venom are caused by 2-methyl-6-alkyl and/or alkenylpiperidine alkaloids. The variation in piperidine alkaloid structures has useful taxonomic characters. The most well studied Solenopsis species is S. invicta, which was accidentally imported into the USA in the 1930s from South America. It quickly spread throughout the southern USA and is now a major invasive pest ant in the USA and in other parts of the world. Interestingly, the invasive S. invicta has largely displaced a native USA fire ant, S. geminata, from the southern USA. We explore the possibility that differences in venom chemistry could be correlated with this displacement. The cis and trans alkaloids from body extracts of workers and alate queens of S. geminata were separated by silica gel chromatography, identified, and quantitated by GC-MS analysis. Both workers and alate queens produce primarily cis- and trans-2-methyl-6-n-undecyl-piperidines, as well as other minor alkaloid components. Imported fire ant, S. invicta, alate queens produce the same alkaloids as S. geminata alate queens, but in contrast S. invicta workers produce piperidine alkaloids with longer side chains, which are purported to be physiologically more effective. These results are discussed in relation to the evolutionary progression of fire ant venom alkaloids and displacement of S. geminata by S. invicta in the USA.

Community-based participatory research (CBPR) has great potential to address cancer disparities, particularly in racially and ethnically diverse and underserved neighborhoods. The objective of this study was to conduct a process evaluation of an innovative academic-community partnership, Queens Library HealthLink, which aimed to reduce cancer disparities through neighborhood groups (Cancer Action Councils) that convened in public libraries in Queens, New York. We used a mixed-methods approach to conduct 69 telephone survey interviews and 4 focus groups (15 participants) with Cancer Action Council members. We used 4 performance criteria to inform data collection: action or attention to sustainability, library support for the council, social cohesion and group leadership, and activity level. Focus group transcripts were independently coded and cross-checked for consensus until saturation was achieved. Members reported benefits and barriers to participation. Thirty-three original focus group transcript codes were organized into 8 main themes related to member experiences: 1) library as a needed resource, 2) library as a reputable and nondenominational institution, 3) value of library staff, 4) need for a HealthLink specialist, 5) generation of ideas and coordination of tasks, 6) participation challenges, 7) use of community connections, and 8) collaboration for sustainability. In response to the process evaluation, Cancer Action Council members and HealthLink staff incorporated member suggestions to improve council sustainability. The councils merged to increase intercouncil collaboration, and institutional changes were made in funding to sustain a HealthLink specialist beyond the grant period.

Full Text Available The article analyses the connection between modalities of letter writing and the relation between writer and addressee. We take into consideration the case of Elizabeth I of England, situated in the overall panorama of early modern European historiography. The English Queen was a prolific and skilful letter writer, endowed with an uncommon talent for foreign languages; but she was also, thanks to her role, the willing or unwilling recipient of thousands of epistles. By selecting two different corpora of letters, from and to the Queen, it is possible to explore how personal relations, degree of acquaintance, respective status and purpose of the letter influence the very structure of the genre.
