1981-01-01

Indoor and outdoor concentrations of lead and bromine have been measured at a nursery school, using streaker samplers with 2.4 h resolution. The observed variations in concentration were well-correlated with traffic intensity variations. In addition to their closely related time-variation curves, the bromine to lead ratios pointed to the emissions from leaded gasoline-powered vehicles as the main source of these elements both in and outdoors. Time-variation patterns on weekdays and during weekends indicated that the lead and bromine containing particles entered the nursery school mainly by leaking. Only a minor fraction seemed to be brought in and resuspended by the staff and children. The indoor concentrations of the elements studied were about 5 times lower than the outdoor levels thus considerably reducing the indoor exposure. (orig.)

Full Text Available Results are presented of investigations on value orientations of students future nursery-school teachers, as manifested by preferences of certain lifestyles. The aim was to examine if there is stability or change in the desirability of some lifestyles in three generations of students of Higher School for Nursery-School Teacher Training. Examinations were carried out on preferences of the following lifestyles: hedonistic, utilitarian altruistic, aesthetic, orientation to power and social standing, cognitive self-realization and Promethean activism. The obtained results indicate a certain stability in student value profile throughout the study period but also certain changes. In the value profile of future nursery-school teachers self-realization emerges consistently in the examined generations as the most desirable and accepted lifestyle. Then, the tendency to gradually decline was found in aesthetic, utilitarian, cognitive, altruistic Promethean, hedonistic and orientation to power and social standing lifestyles of which the last one consistently occurred in three generations as the least desirable lifestyle. Changes were manifested in the increasing desirability of utilitarian lifestyle from the first to the third generation as well as in gradual decline of desirability degree in self realization and aesthetic lifestyles. Also, the trend of increasing agreement between lifestyle students prefer and their current lifestyle was noticeable.

This study aimed to evaluate the hearing screening of pre-school children at nursery schools in Tyrol, Austria. 47 nursery schools with a total of 2199 enrolled children participated in the study. At the screening, the children were presented a series of tones at frequencies 0.5 kHz (25dB), 1 kHz, 2 kHz, 3 kHz, and 4 kHz (20 dB each) from portable audiometers. The tones were presented over headphones for each ear separately and at irregular intervals. Failure to respond to any of the frequencies was considered failure of the screening. Parents were then advised in written form to have the child examined by an ENT-specialist. 1832 individuals were screened (coverage: 83% of nursery school children; corresponding to at least 63% of all Tyrolean children aged 3 to 5 years). Of these, 390 failed the test (referral rate: 21% of all screened). Examination through an ENT-specialist occurred with 217 children, and this confirmed the positive test in 139 children (hit rate: 64%). In most cases, a temporary conductive hearing loss due to external or middle ear problems (glue ear, tube dysfunction, cerumen, otitis media) was diagnosed. A sensorineural hearing loss was found in 4 children (in 3 of them bilateral). The need for therapy was recognized in 81 children (4% of all screened). Pre-school hearing screening identifies children with ear and hearing problems that need therapeutical intervention. Although the hearing problems are mostly of a temporary nature, some may require monitoring over some period. Also some children with permanent sensorineural hearing loss may be detected through this measure. Hearing screening is an efficient means of assessing ear and hearing problems in pre-school children. However, the follow-up rate needs to be improved for optimizing the efficacy.

Full Text Available Indoor air quality (IAQ in nursery school is believed to be different from elementary school. Moreover, younger children are more vulnerable to air pollution than higher grade children because they spend more time indoors, and their immune systems and bodies are less mature. The purpose of this study was to compare the concentrations of the monoaromatic volatile benzene, toluene, ethylbenzene m,p-xylene and o-xylene (BTEX in urban nursery schools located in Gliwice, Poland. The nursery schools were chosen to include areas with different urbanization and traffic density characteristics in order to gather a more diverse picture of exposure risks in the various regions of the city. BTEX were sampled during winter and spring seasons in older and younger children classrooms. The samples were thermally desorbed (TD and then analyzed with use of gas chromatography (GC. In addition, outdoor measurements were carried out in the playground at each nursery school. BTEX quantification, indoor/outdoor concentration, and correlation coefficients were used to identify pollutant sources. Elevated levels of o-xylene and ethylbenzene were found in all monitored classrooms during the winter season. Outdoor concentrations were lower than indoors for each classroom. Indicators based on health risk assessment for chronic health effects associated with carcinogenic benzene or non-carcinogenic BTEX were proposed to rank sites according to their hazard level.

Nursery schools serve as reservoirs of transmission of infectious diseases, and teachers should be able to implement and monitor hygiene measures to prevent them. The aim of the present study was to assess the compliance of nursery school teachers on promoting preventive interventions and to identify associated factors, during the novel H1N1 influenza pandemic. A secondary objective was to evaluate their knowledge and vaccination status regarding the novel virus. A cross-sectional study was performed, with the use of a predesigned anonymous, questionnaire, and distributed to all public nursery teachers of Athens, Greece. General etiquette practices were highly acceptable to over 92% of teachers. Those with longer teaching experience promoted simple preventive measures, such as hand washing and use of hand sanitizer, more often while older children were more likely to familiarize with them. However, teachers presented inadequate knowledge concerning the novel virus and their vaccination rates with the pandemic vaccine were unacceptably low (1.1%). Our study showed that promotion of simple preventive measures is feasible and may contribute to the prevention of outbreaks in nursery schools, although knowledge gaps and fear concerning the pandemic vaccine highlight communication issues.

To identify the characteristics of health education and promotion interventions in Spanish nursery and primary schools, through the studies published in scientific journals. We performed a review of studies on health education and promotion interventions in Spanish nursery and primary schools, published from 1995 to 2005. The information sources were Medline (through Pubmed), Cinhal, Eric, Sociological Abstracts, Science Citation Index, and Isooc (CSIC). Studies performed in Spanish nursery and primary schools that incorporated health education and promotion interventions were selected. The studies' general features, main subject and aims, methodology, the kind of intervention described, and compliance with the criteria for Healthy Schools were analyzed. Only 26 of the 346 articles identified met the inclusion criteria. Health education programs focussed more on disease prevention than on health promotion and only a few studies were performed in nursery and primary schools. The criteria for health promotion in schools were included in 5 articles (19.2%). The importance of health institutions (n = 7; 26.9%) and universities (n = 8; 30.8%) as promoters of programs was notable. The most frequent subject was smoking (n = 11; 42.3%). Teachers play a lesser role in health promotion in schools than health institutions in the implementation and dissemination of health programs. Research into health promotion in nursery and primary schools is scarce.

Children's exposure to air pollutants is an important public health challenge. Indoor air quality (IAQ) in nursery school is believed to be different from elementary school. Moreover, younger children are more vulnerable to air pollution than higher grade children because they spend more time indoors, and their immune systems and bodies are less mature. The purpose of this study was to evaluate the indoor air quality (IAQ) at naturally ventilated rural nursery schools located in Upper Silesia, Poland. We investigated the concentrations of volatile organic compounds (VOCs), particulate matter (PM), bacterial and fungal bioaerosols, as well as carbon dioxide (CO2) concentrations in younger and older children's classrooms during the winter and spring seasons. The concentration of the investigated pollutants in indoor environments was higher than those in outdoor air. The results indicate the problem of elevated concentrations of PM2.5 and PM10 inside the examined classrooms, as well as that of high levels of CO2 exceeding 1,000 ppm in relation to outdoor air. The characteristics of PM and CO2 levels were significantly different, both in terms of classroom occupation (younger or older children) and of season (winter or spring).

Based on an investigation on organizational well-being in the Municipality of Venice (2009), we examined 110 public nursery school and preschool teachers working in the Venice and Marghera districts. The aim of this study was to develop and implement a procedure for work-related stress assessment and management in Municipality of Venice, in the light of Law 81/2008. Occupational stress and its impact on teachers' well-being and health were assessed by means of self-administered questionnaires and semi-structured interviews. Descriptive analyses were conducted to compare teachers' data with those concerning employees operating in other services in the Venice and Marghera districts. According to the results, while nursery school and preschool teachers work with considerable commitment, vigor, dedication and involvement, problems were observed related to: assignment of administrative tasks without appropriate support from the district offices; difficult access to support services; shortage of temporary teachers and auxiliary personnel and, limited to some facilities, lack of adequate physical space devoted to teaching activities. Such adverse conditions result in an increase in vigilance levels required to ensure children's safety. Personnel also suffer from a lack of career prospects, with scarce opportunities for contact with other facilities in the area and inadequate involvement in the decisional processes at Municipality level. Improving such adverse conditions could solve the current marginalization of public nursery school and preschool teachers and encourage mutual exchange of information, which would in turn favour more appropriate methods of managing each single facility.

2015-07-01

Full Text Available Indoor air quality (IAQ in nursery schools is an emerging public health challenge. Particular attention should be paid to younger children, because they are more vulnerable to air pollution than older children. Among air pollutants, fine particulate matter (PM2.5 is of the greatest interest mainly due to its strong association with acute and chronic effects on children’s health. In this paper, we present concentrations of PM2.5 and the composition of its trace elements at naturally ventilated nursery schools located in the area of Gliwice, Poland. The nursery schools were selected to characterize areas with different degrees of urbanization and traffic densities during the winter and spring seasons. The results indicate there is a problem with elevated concentrations of PM2.5 inside the examined classrooms. The children’s exposure to trace elements was different based on localization and season. PM2.5 concentration and its trace element composition have been studied using correlation coefficients between the different trace elements, the enrichment factor (EF and principal component analysis (PCA. PCA allowed the identification of the three components: anthropogenic and geogenic sources (37.2%, soil dust contaminated by sewage sludge dumping (18.6% and vehicular emissions (19.5%.

In the 241st issue of Echo, the Staff Association shared its concerns about the future of the CERN Nursery school. Indeed, the EVEE ‘Espace de vie Enfantine et École’ has faced significant financial difficulties in the last few years. According to an audit carried out in 2015, overall the management is sound, but the report shows that the potential gains are not sufficient to restore budgetary balance. Naturally, the EVEE is turning to CERN in order for the Organization to increase its commitment to ensure the sustainability of this structure which is crucial for the lives of many CERN families. To this end, a joint working group has been set up by Martin Steinacher, Director for Finance and Human Resources, who has given the mandate (see below) and established the composition of the group. This joint working group being technical in nature, it will also be necessary to hold political discussions between the Staff Association and the Management. An internal working group of t...

2011-10-01

To explore nutrition and food provision in pre-school nurseries in order to develop interventions to promote healthy eating in pre-school settings. Quantitative data were gathered using questionnaires and professional menu analysis. In the community, at pre-school nurseries. All 130 nurseries across Liverpool were a sent questionnaire (38 % response rate); thirty-four menus were returned for analysis (26 % response rate). Only 21 % of respondents stated they had adequate knowledge on nutrition for pre-school children. Sixty-one per cent of cooks reported having received only a 'little' advice on healthy eating and this was often not specific to under-5 s nutrition. Fifty-seven per cent of nurseries did not regularly assess their menus for nutritional quality. The menu analysis revealed that all menus were deficient in energy, carbohydrate, Fe and Zn. Eighty-five per cent of nurseries had Na/salt levels which exceed guidelines. Nurseries require support on healthy eating at policy, knowledge and training levels. This support should address concerns relating to both menu planning and ingredients used in food provision and meet current guidelines on food provision for the under-5 s.

Career choice motivation and value priorities of future nursery and elementary school teachers

Marušić-Jablanović Milica V.

2016-01-01

Full Text Available The paper presents a study that aimed to establish the nature of the link between the value orientation of future nursery and elementary school teachers and the motivation for their career choice. Two instruments were used - the Schwartz Portrait Values Questionnaire (PVQ-21 and the Career Choice Scale. The findings suggest that the motivation for the respondents' career choice and their value orientation are relatively homogeneous, but also that two groups of students can be distinguished according to dominant motivating factors, and that these two groups also differ in their value priorities. Non-parametric correlation showed that each type of motivation reflected different values - in individuals whose dominant motivation was intrinsic, the values of benevolence, self-direction and achievement were more pronounced, while stronger altruistic motivation correlated with more pronounced values of benevolence and universalism. On the other hand, extrinsic motivation correlated with the values of hedonism and power, which the initial theoretical model locates at the opposite end to the values corresponding to altruistic motivation. The research findings are important for understanding the reasons behind nursery and elementary school teachers' career choice and the goals they are guided by in their life and work, and are also important for the career guidance process.

Objectives Detecting outbreaks early and then activating countermeasures based on such information is extremely important for infection control at childcare facilities. The Sumida ward began operating the Nursery School Absenteeism Surveillance System (NSASSy) in August 2013, and has since conducted real-time monitoring at nursery schools. The Public Health Center can detect outbreaks early and support appropriate intervention. This paper describes the experiences of Sumida Public Health Center related to early detection and intervention since the initiation of the system.Methods In this study, we investigated infectious disease outbreaks detected at 62 nursery schools in the Sumida ward, which were equipped with NSASSy from early November 2013 through late March 2015. We classified the information sources of the detected outbreak and responses of the public health center. The sources were (1) direct contact from some nursery schools, (2) messages from public officers with jurisdiction over nursery schools, (3) automatic detection by NSASSy, and (4) manual detection by public health center officers using NSASSy. The responses made by the health center were described and classified into 11 categories including verification of outbreak and advice for caregivers.Results The number of outbreaks detected by the aforementioned four information sources was zero, 25, 15, and 7 events, respectively, during the first 5 months after beginning NSASSy. These numbers became 5, 7, 53, and 25 events, respectively, during the subsequent 12 months. The number of outbreaks detected increased by 47% during the first 5 months, and by 87% in the following 12 months. The responses were primarily confirming the situation and offering advice to caregivers.Conclusion The Sumida Public Health Center ward could achieve early detection with automatic or manual detection of NSASSy. This system recently has become an important detection resource, and has contributed greatly to early

The objective of this study was to determine some common behavioural risk factors for intestinal helminthiasis in nursery and primary school children in Enugu. A cross-sectional survey on 460 children attending nursery and primary schools in Enugu was carried out in 2003 with a view to determine some behavioural risk factors for intestinal helminthiasis. This study was carried out in the research laboratory of the Federal Ministry of Health, National Arbovirus and Vector Research Centre, Enugu. Intestinal helminthiasis was diagnosed using the kato-katz method in analysing fresh stool samples collected from nursery and primary school children in Enugu. These fresh stool samples were collected into appropriately labeled clean containers. Questionnaires were administered by the researchers to obtain data from the children and their parents or guardians as regards some behavioural risk factors for intestinal helminthiasis. The results from this study showed that the prevalence of intestinal helminthiasis was significantly affected by various behavioural risk factors. The rate of helminthic infection varied significantly with hand washing habits after defeacation (chi2 = 75.77; df= 2; p = 0.001) and with different habits of washing fruits before eating (chi2 = 52.79; df=2; p = 0.001) among the pupils. Also, the rate ofhelminthic infection varied significantly with the source of drinking water (chi2 = 55.12; df = 3; p = 0.01), water boiling habits (chi2 = 40.89; df = 2; p = 0.001), use of footwear after school hours (chi2 = 30.72; df = 2; p = 0.001). Sites utilized for defeacation by the pupils (chi2 = 80.25; df=3; p = 0.001) also significantly influenced the rate ofhelminthic infection. Various behavioural factors which significantly affect the rate of helminthic infection abound in children living in Enugu. The government should give attention to the control of these behavioural risk factors. A lot of health education will be needed to curb the poor personal hygienic

2016-01-01

This study examined the influence of neonatal nursery design on interactions between nurses and mothers of infants in the nursery. We used a natural quasi-experimental design, using semi-structured interviews and a structured measure of mothers' and nurses' perceptions of nursing care, to compare mothers (n=26 and n=40) and nurses (n=22 and n=29) in an open-bay (OB) nursery and a single family room (SFR) nursery. Thematic analysis was used to generate key themes from the interviews. Mothers and nurses in both nursery designs talked about Valuing interactions; the importance of interactions between mothers and nurses. Mothers and nurses described SFRs as providing a space, My/their room, which enhanced mothers' sense of control and connection with the infant. SFRs were also associated with Changing the norms of interactions with nurses and other mothers, which created challenges in the desired quantity and quality of interactions for mothers and nurses. Nurses in the SFR nursery also reported Enhanced interactions, including improved confidentiality and personalized communication. Mothers in the OB nursery reported more supportive mothering actions from nurses than mothers in the SFR nursery. Both mothers and nurses in the OB nursery also talked about Our nursery community, which captured the value of having other nurses and mothers in the rooms. Mothers and nurses perceived that the SFR nursery enhanced privacy and maternal closeness for mothers compared to the OB nursery. However, the SFR nursery design presented challenges to some interactions of value to nurses and mothers. Copyright © 2016 Elsevier Inc. All rights reserved.

Although early life education for improved long-term health and the amelioration of socioeconomically generated inequalities in chronic disease is advocated in influential policy statements, the evidence base is very modest. To address this dearth of evidence using data from a representative UK national birth cohort study. The analytical sample comprised men and women in the 1958 birth cohort study with prospectively gathered data on attendance at nursery or primary school before the age of 5 years who had gone on to participate in social survey at 42 years (n=11 374), or a biomedical survey at 44/5 years of age (n=9210), or had data on vital status from 18 to 55 years (n=17 657). Relative to study members who had not attended nursery, in those who had, there was in fact a higher prevalence of smoking and high alcohol intake in middle age. Conversely, nursery attenders had more favourable levels of lung function and systolic blood pressure in middle age. This apparent association between nursery attendance and lower systolic blood pressure was confined to study members from more deprived social backgrounds of origin (P value for interaction 0.030). There was no apparent link between early school attendance and any behavioural or biological risk factor. Neither nursery nor early school attendance was clearly related to mortality risk. We found no clear evidence for an association of either attendance at nursery or primary school before the age of 5 years and health outcomes around four decades later. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available This paper aims at finding out the forms and functions of directive speech acts uttered by Persian-speaking children. The writer’s goal is to discover the distinct strategies applied by speakers of nursery school age children regarding three parameters: the choice of form, the negotiation of communicative goals within conversation, and the protection of face. The data collected for this purpose are based on actual school conversational situations that were audio recorded in four nursery schools during classroom work and playtime activities. Children, who are the subjects of this study, are of both sexes and various social backgrounds. The results revealed that (1 the investigation of children’s directive speech acts confirm the fact that they are aware of social parameters of talk (Andersen- Slosberg,1990; Ervin, Tripp et al., 1990; (2 they use linguistic forms that are different from what is used by adults as politeness marker, such as, polite 2nd plural subject-agreement on the verb, “please” and “thank you” words; (3 They use declaratives with illocutionary force in order to mark distance (Georgalidou, 2001.

During October 2014, enterovirus (EV) RNA was detected in the stools of four children attending the same class in a nursery school, and hospitalized with mild febrile and vomiting disease in Parma, Italy. Upon sequencing, the viruses were characterized as EV71 subgenogroup C2. Phylogenetic analysis of the four EV71 C2 viruses allowed the distinction of a diverging lineage within subgenogroup C2, containing the Italian EV71 C2 strains and viruses detected in France in 2013. The identification of an outbreak of EV71 C2 in Italy extended information on the geographic diffusion and clinical relevance of these viruses in Europe.

2016-07-04

Although noise is one of the leading work-related health risk factors for teachers, many nursery schools lack sufficient noise reduction measures. This intervention study evaluated the noise exposure of nursery school teachers when dropping DUPLO toy bricks into storage cases. Sound analyses of the impact included assessment of the maximum sound pressure level (LAFmax) as well as frequency analyses with 1/3 octave band filter. For the purpose of standardization, a customized gadget was developed. Recordings were performed in 11 cases of different materials and designs to assess the impact on sound level reduction. Thereby, the acoustic effects of three damping materials (foam rubber, carpet, and PU-foam) were investigated. The lowest LAFmax was measured in cases consisting of "metal grid" (90.71 dB) or of a woven willow "basket" (91.61 dB), whereas a case of "aluminium" (103.34 dB) generated the highest impact LAFmax. The frequency analyses determined especially low LAFmax in the frequency bands between 80 and 2500 Hz in cases designs "metal grid" and "basket". The insertion of PU-foam achieved the most significant attenuation of LAFmax (-13.88 dB) and, in the frequency analyses, the best sound damping. The dropping of DUPLO bricks in cases contributes to the high noise level in nursery schools, but measured LAFmax show no evidence for the danger of acute hearing loss. However, continuous exposure may lead to functional impairment of the hair cells and trigger stress reactions. We recommend noise reduction by utilizing cases of woven "basket" with an insert of PU-foam.

[Nursery Teacher's Stress Scale (NTSS): reliability and validity].

Akada, Taro

2010-06-01

This study describes the development and evaluation of the Nursery Teacher's Stress Scale (NTSS), which explores the relation between daily hassles at work and work-related stress. In Analysis 1, 29 items were chosen to construct the NTSS. Six factors were identified: I. Stress relating to child care; II. Stress from human relations at work; III. Stress from staff-parent relations; IV. Stress from lack of time; V. Stress relating to compensation; and VI. Stress from the difference between individual beliefs and school policy. All these factors had high degrees of internal consistency. In Analysis 2, the concurrent validity of the NTSS was examined. The results showed that the NTSS total scores were significantly correlated with the Job Stress Scale-Revised Version (job stressor scale, r = .68), the Pre-school Teacher-efficacy Scale (r = -.21), and the WHO-five Well-Being Index Japanese Version (r = -.40). Work stresses are affected by several daily hassles at work. The NTSS has acceptable reliability and validity, and can be used to improve nursery teacher's mental health.

With 796,500 places available for children in England, pre-school nurseries could serve as an important setting for population-wide dietary intervention. It is critical to understand the determinants of healthy food provision in this setting, which may include access to food stores. This study examined the association between objective, GIS-derived supermarket proximity and fruit and vegetable serving frequency, using data from 623 English nurseries. Overall, 116 (18%) nurseries served fruits and vegetables infrequently (supermarket proximity. In adjusted multivariable regression models, nurseries farthest from their nearest supermarket (Q5, 1.7-19.8km) had 2.38 (95% CI 1.01-5.63) greater odds of infrequent provision. Our results suggest that supermarket access may be important for nurseries in meeting fruit and vegetable provision guidelines. We advance a growing body of international literature, for the first time linking the food practices of institutions to their neighbourhood food retail context. Copyright © 2017 The Authors.

The aim of this study was to characterize the relationship between Indoor Air Quality (IAQ) and ventilation in French classrooms. Various parameters were measured over one school week, including volatile organic compounds, aldehydes, particulate matter (PM2.5 mass concentration and number concentration), carbon dioxide (CO2 ), air temperature, and relative humidity in 51 classrooms at 17 schools. The ventilation was characterized by several indicators, such as the air exchange rate, ventilation rate (VR), and air stuffiness index (ICONE), that are linked to indoor CO2 concentration. The influences of the season (heating or non-heating), type of school (nursery or elementary), and ventilation on the IAQ were studied. Based on the minimum value of 4.2 l/s per person required by the French legislation for mechanically ventilated classrooms, 91% of the classrooms had insufficient ventilation. The VR was significantly higher in mechanically ventilated classrooms compared with naturally ventilated rooms. The correlations between IAQ and ventilation vary according to the location of the primary source of each pollutant (outdoor vs. indoor), and for an indoor source, whether it is associated with occupant activity or continuous emission. © 2015 John Wiley & Sons A/S.

Full Text Available We present in this paper some of the results of a research which took place in the Principality of Asturias with the purpose of analyzing the gender socialization processes in nursery education, using the points of view narrated by the teachers. Although we will not be providing an exhaustive list of conclusions reached so far, we do put forward one of the aspects which has been developed throughout the research; that is, the comments and opinions of the teachers about the influence that the family and the school have on the process of gender construction. The discourse developed about this field will allow us to elucidate if a system based on opinion and belief that legitimizes the postulates of mixed school and dulls the implementation of coeducation processes still persists.

Full Text Available Inclusive education in Brazil has been widely discussed in all areas of the educational. The inclusion of pupils with special educational needs (SEN in mainstream schools is increasingly frequent, though still many aspects need to be rethought. This work aimed at checking how the subjects with SEN in Early Stimulation age, from zero to three years and 11 months are included into the regular classroom environment, at Nursery Schools, of an average municipality - Vale dos Sinos. This work involved a cross-sectional survey of quantitative and descriptive statistics. The data collection was carried out directly from a structured questionnaire with open and closed questions, directed to all principals of the thirteen Nursery Schools in the referred municipality. From the thirteen schools of the municipality only one did not take part of the research since there was no enrollment of children with special needs there, totalizing 46 children in processes of educational inclusion. From those, twelve children (26.8% were benefited with an Early Stimulation service maintained by the Association of Parents and Friends of Exceptional Children of that referred municipality, Thirty children (65,2% enrolled in school at the initiative of his own family e four children (8% by intervention of the Wakefield council. In this sense, we believe that the professionals of the Early Stimulation have the responsibility of promoting and conveying its importance and, mainly, the benefits of Early Stimulation for the whole development of individuals, as well as its contribution to a process of inclusive education.

Context dimensions of nursery school seen through the eyes of trainee preschool teachers

Directory of Open Access Journals (Sweden)

Lazić Svetlana T.

2017-01-01

Full Text Available By shifting the focus of research from the child to the study of educational practice in the context of a specific setting, time, people and their relationships, significant observations have been made regarding the importance of these dimensions, their possible changes, and their influence on children's development. Young children live in the moment, and the experiences they are exposed to within contextual dimensions affect their understanding and experience of the world, which highlights the need to assess the extent to which the students of the Higher Professional School for the Education of Preschool Teachers in Novi Sad have been sensitized to recognize and assess the importance of each dimension of context. The data were collected in the academic year 2015-16 through systematic observation during students' practical training as part of a course from the elective nursery school module. The students' reports show that they understood the theoretical framework which they referred to in their assessment of contextual dimensions. In the study, particular attention was devoted to students' understanding of their role in the construction, verification and improvement of each dimension. Students do not feel sufficiently prepared for such activities and believe that they need practical experience. Since this is one of the ways in which they acquire practical experience in the course of their undergraduate studies, we recommend that compulsory and elective courses provide students with additional exposure to observations on the importance of space, time and interaction, that students be supported in developing a creative approach and in understanding their personal contribution to the introduction of changes.

Investigate the effect of a theory-based intervention on oral-health knowledge, attitudes and behaviours of early years staff (EYS), parents and nursery children. Qualitative research with staff and parents from eight nurseries through interviews/focus groups. An intervention was developed and piloted using pre-posttest design. Nurseries in deprived communities in Dundee, Scotland. 111 children aged 3-5 years attending nursery, including 79 parents and 8 nursery staff. Staff session targeted outcome expectancies, subjective norms and self-efficacy for tooth-brushing in nursery using information provision, modelling and goal-setting, followed by a three-week intervention. Parent-child dyads received a leaflet with instructions for goal-setting, planning and monitoring home brushing. Tooth-brushing self-monitoring materials (e.g. two-minute timer, diaries) were used and certificates provided in the nursery as rewards. EYS knowledge, attitudes and behaviours were assessed before and after the intervention using self-report questionnaires. Parents completed interviews assessing beliefs about tooth-brushing and their children's tooth-brushing behaviour at baseline and post-intervention follow-up. Significant improvements in staff knowledge, but not attitudes, self-efficacy, or nursery tooth-brushing were reported. Parent-child dyads completing the intervention were not more likely to report their child carried out twice-daily tooth-brushing at home. The intervention did not improve parents' intentions to brush their child's teeth twice a day or beliefs about the ease of twice-daily tooth-brushing. Only past behaviour significantly predicted posttest brushing. Parents who found brushing easier at baseline were more likely to complete the intervention. Recommendations are made regarding implementing psychological theory and methods into oral-health interventions.

Prolonged or unnecessary antibiotic use is associated with adverse outcomes in infants. Antibiotic stewardship programs (ASPs) aim to prevent these adverse outcomes and optimize antibiotic prescribing. However, data evaluating ASP coverage of nurseries are limited. The objectives of this study were to describe the characteristics of nurseries with and without ASP coverage and to determine perceptions of and barriers to nursery ASP coverage. The 2014 American Hospital Association annual survey was used to randomly select a level III neonatal intensive care unit from all 50 states. A level I and level II nursery from the same city as the level III nursery were then randomly selected. Hospital, nursery, and ASP characteristics were collected. Nursery and ASP providers (pharmacists or infectious disease providers) were interviewed using a semistructured template. Transcribed interviews were analyzed for themes. One hundred forty-six centers responded; 104 (71%) provided nursery ASP coverage. In multivariate analysis, level of nursery, university affiliation, and number of full-time equivalent ASP staff were the main predictors of nursery ASP coverage. Several themes were identified from interviews: unwanted coverage, unnecessary coverage, jurisdiction issues, need for communication, and a focus on outcomes. Most providers had a favorable view of nursery ASP coverage. Larger, higher-acuity nurseries in university-affiliated hospitals are more likely to have ASP coverage. Low ASP staffing and a perceived lack of importance were frequently cited as barriers to nursery coverage. Most nursery ASP coverage is viewed favorably by providers, but nursery providers regard it as less important than ASP providers. © The Author 2016.

The goal of this study was to determine the epidemiology of injuries associated with nursery products among young children treated in US emergency departments. Data from the National Electronic Injury Surveillance System were retrospectively analyzed for patients aged nursery product from 1991 through 2011. An estimated 1 391 844 (95% confidence interval, 1 169 489-1 614 199) nursery product-related injuries among children aged Nursery product-related injuries were most commonly associated with baby carriers (19.5%), cribs/mattresses (18.6%), strollers/carriages (16.5%), or baby walkers/jumpers/exercisers (16.2%). The most common mechanism of injury was a self-precipitated fall (80.0%), and the most frequently injured body region was the head or neck (47.1%). Although successful injury prevention efforts with baby walkers led to a decline in nursery product-related injuries from 1991 to 2003, the number and rate of these injuries have been increasing since 2003. Greater efforts are warranted to prevent injuries associated with other nursery products, especially baby carriers, cribs, and strollers. Prevention of falls and concussions/closed head injuries associated with nursery products also deserves special attention. Copyright © 2017 by the American Academy of Pediatrics.

To analyze 3-year recidivism after release from a prison nursery, a secure unit that allows imprisoned women to care for their infants. Descriptive study of 139 women who co-resided with their infants between 2001 and 2007 in a New York State prison nursery. Administrative criminal justice data were analyzed along with prospective study data on demographic, mental health, and prison nursery policy-related factors. Results reflect a sample of young women of color with histories of clinically significant depressive symptoms and substance dependence, who were convicted of nonviolent crimes and had multiple prior arrests. Three years after release 86.3% remained in the community. Only 4% of women returned to prison for new crimes. Survival modeling indicated that women who had previously violated parole had a significantly shorter mean return to prison time than those who were in the nursery for a new crime. Women released from a prison nursery have a low likelihood of recidivism. Innovative interventions are needed to address incarceration's public health effects. Nurses can partner with criminal justice organizations to develop, implement, and evaluate programs to ensure the health needs of criminal justice involved people and their families are met. © 2013 Wiley Periodicals, Inc.

Administration of prophylactic intravenous immunoglobulins to contacts of infants actively shedding enterovirus during a hospital nursery outbreak may attenuate severity of disease in those contacts and aid in containment of the outbreak. Four cases of neonatal enteroviral disease were treated in our hospital nursery in July and August 2011; 3 were presumed or proven vertical transmission cases and 1 was a presumed horizontal transmission. We aimed to prevent development of severe illness in contacts of affected neonates following a ministry of health advisory during the summer of 2011 warning of increased neonatal enteroviral morbidity and mortality in Israel. Strict infection control measures were implemented, including meticulous decontamination of the nursery environment and administration of intravenous immunoglobulin prophylaxis to contacts. No further horizontal transmission occurred after infection control interventions. Immunoglobulin prophylaxis to control enteroviral infection in the nursery should be considered as an auxiliary infection control intervention during a nursery outbreak.

To determine rates of complications after newborn circumcision by performing a retrospective chart review of patients circumcised at a well-baby nursery, neonatal intensive care units (NICU), and special care nursery (SCN) from 2007 to 2012. A total of 5129 babies (73%) were circumcised at the well-baby nursery and 1909 babies (27%) at the NICU and SCN. Forty-seven patients (0.67%, 95% CI 0.49% to 0.89%) had circumcision-related complications: 5 (0.07%) patients with acute and 42 (0.6%) with late complications. Babies in the NICU/SCN had increased odds of complication (OR 4.00, 95% CI 2.23 to 7.19) compared with those in well-baby nursery. There were increased odds of complications in babies with Caucasian ethnicity (OR 2.60, 95% CI 1.48 to 4.89) compared with African American babies and in babies with private insurance (OR 4.0, 95% CI 2.1 to 7.5) compared with nonprivate insurance. The rates of complications after newborn circumcisions were low. Babies in the NICU/SCN had increased odds of complication. © The Author(s) 2015.

Full Text Available Abstract MAKNA DAN BENTUK DALAM PENERJEMAHAN LAGU-LAGU ANAK Abstract Translating nursery rhymes is not an easy task. The problems of equivalence in meaning and form as well as in the harmony between the translated lyrics and the music are aspects that need to be considered by the translators. By considering nursery rhyme lyric as poetry text, this research analyzes the equivalence of meaning and form in nursery rhymes translation. This research focuses on five nursery rhymes. The meaning analysis was done by conducting particular procedures on translation quality assessment. Meanwhile, the analysis of the form was conducted by comparing the two versions of the nursery rhymes focusing on the sound values. From the equivalence of meaning, the result shows that most nursery rhymes are translated less accurately. On the other hand, the finding of the equivalence in form shows that most of the auditory devices are deleted while most of the rhymes are shifted. This research is expected to give a contribution to song translation activities especially those involving children as the target listeners. Keywords: equivalence, accuracy, sound values, auditory devices, rhymes Abstrak Menerjemahkan lagu anak bukanlah hal yang mudah.

Desert bighorn sheep lambing habitat: Parturition, nursery, and predation sites

Science.gov (United States)

Karsch, Rebekah C.; Cain, James W.; Rominger, Eric M.; Goldstein, Elise J.

2016-01-01

Fitness of female ungulates is determined by neonate survival and lifetime reproductive success. Therefore, adult female ungulates should adopt behaviors and habitat selection patterns that enhance survival of neonates during parturition and lactation. Parturition site location may play an important role in neonatal mortality of desert bighorn sheep (Ovis canadensis mexicana) when lambs are especially vulnerable to predation, but parturition sites are rarely documented for this species. Our objectives were to assess environmental characteristics at desert bighorn parturition, lamb nursery, and predation sites and to assess differences in habitat characteristics between parturition sites and nursery group sites, and predation sites and nursery group sites. We used vaginal implant transmitters (VITs) to identify parturition sites and capture neonates. We then compared elevation, slope, terrain ruggedness, and visibility at parturition, nursery, and lamb predation sites with paired random sites and compared characteristics of parturition sites and lamb predation sites to those of nursery sites. When compared to random sites, odds of a site being a parturition site were highest at intermediate slopes and decreased with increasing female visibility. Odds of a site being a predation site increased with decreasing visibility. When compared to nursery group sites, odds of a site being a parturition site had a quadratic relationship with elevation and slope, with odds being highest at intermediate elevations and intermediate slopes. When we compared predation sites to nursery sites, odds of a site being a predation were highest at low elevation areas with high visibility and high elevation areas with low visibility likely because of differences in hunting strategies of coyote (Canis latrans) and puma (Puma concolor). Parturition sites were lower in elevation and slope than nursery sites. Understanding selection of parturition sites by adult females and how habitat

Effects of marine reserves versus nursery habitat availability on structure of reef fish communities.

Science.gov (United States)

Nagelkerken, Ivan; Grol, Monique G G; Mumby, Peter J

2012-01-01

No-take marine fishery reserves sustain commercial stocks by acting as buffers against overexploitation and enhancing fishery catches in adjacent areas through spillover. Likewise, nursery habitats such as mangroves enhance populations of some species in adjacent habitats. However, there is lack of understanding of the magnitude of stock enhancement and the effects on community structure when both protection from fishing and access to nurseries concurrently act as drivers of fish population dynamics. In this study we test the separate as well as interactive effects of marine reserves and nursery habitat proximity on structure and abundance of coral reef fish communities. Reserves had no effect on fish community composition, while proximity to nursery habitat only had a significant effect on community structure of species that use mangroves or seagrass beds as nurseries. In terms of reef fish biomass, proximity to nursery habitat by far outweighed (biomass 249% higher than that in areas with no nursery access) the effects of protection from fishing in reserves (biomass 21% lower than non-reserve areas) for small nursery fish (≤ 25 cm total length). For large-bodied individuals of nursery species (>25 cm total length), an additive effect was present for these two factors, although fish benefited more from fishing protection (203% higher biomass) than from proximity to nurseries (139% higher). The magnitude of elevated biomass for small fish on coral reefs due to proximity to nurseries was such that nursery habitats seem able to overrule the usually positive effects on fish biomass by reef reserves. As a result, conservation of nursery habitats gains importance and more consideration should be given to the ecological processes that occur along nursery-reef boundaries that connect neighboring ecosystems.

Full Text Available To prevent further range recession, habitat features essential to the life-history requisites of woodland caribou (Rangifer tarandus caribou such as calving and nursery sites need to be protected for the persistence of the species. Woodland caribou may minimize predation risk during calving by either spacing out or spacing away from predators in the forest to calve on islands, wetlands, or shorelines. Our objective was to determine the characteristics of shoreline habitats used as calving and nursery sites by female woodland caribou in northern Ontario. Detailed vegetation and other site characteristics were measured at nursery sites used by cow-calf pairs in Wabakimi and Woodland Caribou Provincial Parks for comparison with shoreline sites that were not used by caribou within each park. Differences in habitat variables selected by female caribou in the two study areas reflect broad ecoregional differences in vegetation and topography. In Wabakimi Provincial Park, understorey tree density and ground detection distance played key roles in distinguishing nursery sites from sites that were not used. In Woodland Caribou Provincial Park, groundcover vegetation and shrub density were important in the selection of nursery sites by female caribou. Generally, female caribou in both parks selected nursery sites with greater slope, lower shrub density but thicker groundcover vegetation, including greater lichen abundance, and higher densities of mature trees than shoreline sites that were not used. The identification of these important features for caribou nursery sites provides a basis for improving their protection in future management policies and legislation.

There have been no reports on the use of "foods allergy disease lifestyle guidance and management forms at day care centers" (life management guidance forms) for understanding details of pupils with food allergies. The contents of lifestyle management guidance forms obtained in Sagamihara city from licensed nurseries were investigated prospectively. We compared and analyzed for the use of life management guidance forms initially in 2013 and in the fiscal year of 2014 in Sagamihara city licensed nurseries. In all, in 2013 and 2014, 9,567 and 10,069 pupils were included in licensed nurseries, and 426 (4.5%) and 447 (4.4%) pupils had food allergies, 61 (0.6%) and 61 (0.6%) had anaphylaxis, respectively.The causative foods in 2013 and 2014, respectively, included unheated hen's egg in 71.6% and 69.6%; heated hen's egg in 54.2% and 54.8%; milk in 23.0% and 23.3%; peanuts in 17.8% and 17.0%; buckwheat in 7.3% and 8.5%; and wheat in 6.3% and 8.3%. There are no significant differences in the distribution of causative foods between 2013 and 2014.Immediate-type food allergy was significantly more frequent in 2014 than in 2013 (73.0% and 78.8%, respectively; p=0.040).

Indoor air pollution mitigation measures are highly important due to the associated health impacts, especially on children, a risk group that spends significant time indoors. Thus, the main goal of the work here reported was the evaluation of mitigation measures implemented in nursery and primary schools to improve air quality. Continuous measurements of CO₂, CO, NO₂, O₃, CH₂O, total volatile organic compounds (VOC), PM₁, PM 2.5 , PM 10 , Total Suspended Particles (TSP) and radon, as well as temperature and relative humidity were performed in two campaigns, before and after the implementation of low-cost mitigation measures. Evaluation of those mitigation measures was performed through the comparison of the concentrations measured in both campaigns. Exceedances to the values set by the national legislation and World Health Organization (WHO) were found for PM 2.5 , PM 10 , CO₂ and CH₂O during both indoor air quality campaigns. Temperature and relative humidity values were also above the ranges recommended by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). In general, pollutant concentrations measured after the implementation of low-cost mitigation measures were significantly lower, mainly for CO₂. However, mitigation measures were not always sufficient to decrease the pollutants' concentrations till values considered safe to protect human health.

Dazeley, Paul; Houston-Price, Carmel

2015-01-01

Activities that engage young children with the sensory properties of foods are popular with nursery schools, despite the lack of evidence for their efficacy in increasing children's consumption of healthy foods. This study provides the first empirical exploration of the effectiveness of a non-taste sensory activity program in a nursery school setting. Ninety-two children aged between 12 and 36 months were allocated either to an intervention group, who took part in looking, listening, feeling and smelling activities with unusual fruits and vegetables every day for 4 weeks, or to a non-intervention control group. In a subsequent mealtime taste test, children touched and tasted more of the vegetables to which they had been familiarized in their playtime activities than of a matched set of non-exposed foods. The results demonstrate that hands-on activities with unfamiliar fruits and vegetables can enhance children's willingness to taste these foods, and confirm the potential for such activities to support healthy eating initiatives.

Since World War II, synthetic fertilizers have been used almost exclusively to grow forest and native plant nursery crops because they are quickly soluble and readily taken up by crops, producing the rapid growth rates that are necessary in nursery culture. In recent years, however, a wide variety of new organic fertilizers have become available. We divided these...

The Scottish Government set out its policy on addressing the poor oral health of Scottish children in 2005. This led to the establishment of Childsmile, a national programme designed to improve the oral health of children in Scotland. One element of the programme promotes daily tooth brushing in all nurseries in Scotland (Childsmile Core). A second targeted component (Childsmile Nursery) offers twice-yearly application of fluoride varnish to children attending nurseries in deprived areas. Studies suggest that fluoride varnish application can reduce caries in both adult and child populations. This trial aims to explore the effectiveness and cost-effectiveness of additional preventive value fluoride varnish application compared to Childsmile Core. The Protecting Teeth@3 Study is an ongoing 2 year parallel group randomised treatment as usual controlled trial. Three-year-old children attending the ante pre-school year are randomised (1:1) to the intervention arm (fluoride varnish & treatment as usual) or the control arm (treatment as usual). Children in the intervention arm will have Duraphat® fluoride varnish painted on the primary tooth surfaces and will continue to receive treatment as usual: the core Childsmile Nursery intervention. Children in the treatment as usual arm will receive the same series of contacts, without the application of varnish and will also continue with the Childsmile Core intervention. Interventions are undertaken by Childsmile trained extended duty dental nurses at six-monthly intervals. Participants receive a baseline dental inspection in nursery and an endpoint inspection in Primary 1 at the age of 5 years old. We will use primary and secondary outcome measures to compare the effectiveness of Duraphat® fluoride varnish plus treatment as usual with treatment as usual only in preventing any further dental decay. We will also undertake a full economic evaluation of the trial. This study is registered at ClinicalTrials.gov. Number: NCT

Nursery plants are important vectors for plant pathogens. Understanding what pathogens occur in nurseries in different production stages can be useful to the development of integrated systems approaches. Four horticultural nurseries in Oregon were sampled every 2 months for 4 years to determine the identity and community structure of Phytophthora spp. associated with different sources and stages in the nursery production cycle. Plants, potting media, used containers, water, greenhouse soil, and container yard substrates were systematically sampled from propagation to the field. From 674 Phytophthora isolates recovered, 28 different species or taxa were identified. The most commonly isolated species from plants were Phytophthora plurivora (33%), P. cinnamomi (26%), P. syringae (19%), and P. citrophthora (11%). From soil and gravel substrates, P. plurivora accounted for 25% of the isolates, with P. taxon Pgchlamydo, P. cryptogea, and P. cinnamomi accounting for 18, 17, and 15%, respectively. Five species (P. plurivora, P. syringae, P. taxon Pgchlamydo, P. gonapodyides, and P. cryptogea) were found in all nurseries. The greatest diversity of taxa occurred in irrigation water reservoirs (20 taxa), with the majority of isolates belonging to internal transcribed spacer clade 6, typically including aquatic opportunists. Nurseries differed in composition of Phytophthora communities across years, seasons, and source within the nursery. These findings suggest likely contamination hazards and target critical control points for management of Phytophthora disease using a systems approach.

Full Text Available Indoor air pollution mitigation measures are highly important due to the associated health impacts, especially on children, a risk group that spends significant time indoors. Thus, the main goal of the work here reported was the evaluation of mitigation measures implemented in nursery and primary schools to improve air quality. Continuous measurements of CO2, CO, NO2, O3, CH2O, total volatile organic compounds (VOC, PM1, PM2.5, PM10, Total Suspended Particles (TSP and radon, as well as temperature and relative humidity were performed in two campaigns, before and after the implementation of low-cost mitigation measures. Evaluation of those mitigation measures was performed through the comparison of the concentrations measured in both campaigns. Exceedances to the values set by the national legislation and World Health Organization (WHO were found for PM2.5, PM10, CO2 and CH2O during both indoor air quality campaigns. Temperature and relative humidity values were also above the ranges recommended by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE. In general, pollutant concentrations measured after the implementation of low-cost mitigation measures were significantly lower, mainly for CO2. However, mitigation measures were not always sufficient to decrease the pollutants’ concentrations till values considered safe to protect human health.

The South African Experience of Conservation and Social Forestry Outreach Nurseries

Science.gov (United States)

Botha, Jenny; Witkowski, Ed T. F.; Cock, Jacklyn

2006-11-01

Outreach nurseries are favored conservation and social forestry tools globally, but, as with many integrated conservation and development programs (ICDPs), they do not always produce anticipated results. A synopsis of the experience of South African practitioners is provided in this study of 65 outreach nurseries. South African outreach nurseries frequently include financial objectives, creating additional challenges in simultaneously attaining conservation and socioeconomic goals. Progress was hindered by biophysical problems (e.g., lack of water, poor soils, etc.) as well as the harsh socioeconomic conditions facing most communities in which nurseries had been established. Attaining financial viability was challenging. Business management skills were often restricted, and few viability studies included adequate market research. Costs to community participants were usually high, and benefits were limited. Conservation objectives were frequently lost in the struggle to attain financial viability. The management of social processes also proved challenging. Although small scale and relatively straightforward compared with many ICDPs, nurseries usually require substantial institutional support, including a range of technical, business, and development services. Project time frames need to be reconsidered, as practitioners estimate that it takes 5-10 years for nurseries to start meeting objectives, and donors and implementing agencies often operate on 2-3-year project cycles. Detailed viability studies are essential, incorporating a social probe and an assessment of potential impacts of projects on community participants. Progress needs to be continuously evaluated to enable institutions and community participants to adapt to changing conditions as well as ensure that the spectrum of objectives are being achieved.

Full Text Available The present study was an attempt to investigate the effect of nursery rhymes on the young language learners listening comprehension ability. To do so, 30 elementary learners were selected as the potential participants of the study. The learners’ perceptions about using nursery rhymes in teaching listening as well as teachers’ perceptions about teaching listening comprehension through nursery rhymes were taken into account. The listening pre- and post-tests and teachers and learners’ interviews were employed for data collection procedures. Quantitative as well as qualitative methodologies were adapted for data analysis. Findings showed that the young learners could improve their listening comprehension ability as a result of using nursery rhymes. Interview data also indicated that the learners’ perceptions about nursery rhymes were found to be positive since the rhymes provided an interesting atmosphere for the learners to improve their listening comprehension while benefiting from peer interaction and teacher’s support in the listening classroom. Teachers’ perceptions were also realistic regarding using nursery rhymes in teaching listening, especially for young learners. As to the implication side, finding can contribute to the positive application of nursery rhymes in paving the way for young learners to improve their listening comprehension ability.

2012-01-01

A survey was conducted to evaluate average levels of indoor radon and gamma doses in all educational buildings (506 schools) located in South-East Italy (the Salento peninsula, province of Lecce). In this paper the final findings relating to measurements performed with SSNTD dosemeters in 438 schools (86% of the sample) are reported. The average annual activity concentration of radon in schools located in the province of Lecce is 209 ± 9 Bq/m 3 . Radon values actually ranged from 21 Bq/m 3 to 1608 Bq/m 3 . About 7% of schools showed radon concentration values above 500 Bq/m 3 , the Italian action level for workplaces. - Highlights: ► The annual radon concentration in schools of the province of Lecce is 209 ± 9 Bq/m 3 . ► Schools radon values (209 ± 9 Bq/m 3 ) are higher than the regional average (52 ± 2 Bq/m 3 ). ► Nursery schools showed higher radon values. ► Nursery schools had the highest percentage of schools (12%) over 500 Bq/m 3 .

Byrne, Mary W.; Goshin, Lorie; Blanchard-Lewis, Barbara

2011-01-01

Prison nurseries prevent maternal separations related to incarceration for the small subset of children whose pregnant mothers are incarcerated in states with such programs. For a cohort of 100 children accepted by corrections into one prison nursery, subsequent separation patterns are analyzed. The largest numbers are caused by corrections’ removal of infants from the nursery and infants reaching a one-year age limit. Criminal recidivism and substance abuse relapse threaten continued mothering during reentry. Focused and coordinated services are needed during prison stay and reentry years to sustain mothering for women and children accepted into prison nursery programs. PMID:22328865

Genotypic Diversity of Phytophthora cinnamomi and P. plurivora in Maryland's Nurseries and Mid-Atlantic Forests.

Beaulieu, Justine; Ford, Blaine; Balci, Yilmaz

2017-06-01

Genetic diversity of two Phytophthora spp.-P. cinnamomi (102 isolates), commonly encountered in Maryland nurseries and forests in the Mid-Atlantic United States, and P. plurivora (186 isolates), a species common in nurseries-was characterized using amplified fragment length polymorphism. Expected heterozygosity and other indices suggested a lower level of diversity among P. cinnamomi than P. plurivora isolates. Hierarchical clustering showed P. cinnamomi isolates separated into four clusters, and two of the largest clusters were closely related, containing 80% of the isolates. In contrast, P. plurivora isolates separated into six clusters, one of which included approximately 40% of the isolates. P. plurivora isolates recovered from the environment (e.g., soil and water) were genotypically more diverse than those found causing lesions. For both species, isolate origin (forest versus nursery or among nurseries) was a significant factor of heterozygosity. Clonal groups existed within P. cinnamomi and P. plurivora and included isolates from both forest and nurseries, suggesting that a pathway from nurseries to forests or vice versa exists.

Noise Exposure of Teachers in Nursery Schools—Evaluation of Measures for Noise Reduction When Dropping DUPLO Toy Bricks into Storage Cases by Sound Analyses

Directory of Open Access Journals (Sweden)

Konstanze Gebauer

2016-07-01

Full Text Available Background: Although noise is one of the leading work-related health risk factors for teachers, many nursery schools lack sufficient noise reduction measures. Methods: This intervention study evaluated the noise exposure of nursery school teachers when dropping DUPLO toy bricks into storage cases. Sound analyses of the impact included assessment of the maximum sound pressure level (LAFmax as well as frequency analyses with 1/3 octave band filter. For the purpose of standardization, a customized gadget was developed. Recordings were performed in 11 cases of different materials and designs to assess the impact on sound level reduction. Thereby, the acoustic effects of three damping materials (foam rubber, carpet, and PU-foam were investigated. Results: The lowest LAFmax was measured in cases consisting of “metal grid” (90.71 dB or of a woven willow “basket” (91.61 dB, whereas a case of “aluminium” (103.34 dB generated the highest impact LAFmax. The frequency analyses determined especially low LAFmax in the frequency bands between 80 and 2500 Hz in cases designs “metal grid” and “basket”. The insertion of PU-foam achieved the most significant attenuation of LAFmax (−13.88 dB and, in the frequency analyses, the best sound damping. Conclusion: The dropping of DUPLO bricks in cases contributes to the high noise level in nursery schools, but measured LAFmax show no evidence for the danger of acute hearing loss. However, continuous exposure may lead to functional impairment of the hair cells and trigger stress reactions. We recommend noise reduction by utilizing cases of woven “basket” with an insert of PU-foam.

2016-02-01

On 30 May 2012, Surrey and Sussex Health Protection Unit was called by five nurseries reporting children and staff with sudden onset vomiting approximately an hour after finishing their lunch that day. Over the following 24 h 50 further nurseries supplied by the same company reported cases of vomiting (182 children, 18 staff affected). Epidemiological investigations were undertaken in order to identify the cause of the outbreak and prevent further cases. Investigations demonstrated a nursery-level attack rate of 55 out of 87 nurseries (63·2%, 95% confidence interval 52·2-73·3). Microbiological tests confirmed the presence of Bacillus cereus in food and environmental samples from the catering company and one nursery. This was considered microbiologically and epidemiologically consistent with toxin from this bacterium causing the outbreak. Laboratory investigations showed that the conditions used by the caterer for soaking of pearl haricot beans (known as navy bean in the USA) used in one of the foods supplied to the nurseries prior to cooking, was likely to have provided sufficient growth and toxin production of B. cereus to cause illness. This large outbreak demonstrates the need for careful temperature control in food preparation.

Carroll, Fran E; Rooshenas, Leila; Owen-Smith, Amanda; Al-Janabi, Hareth; Hollinghurst, Sandra; Hay, Alastair D

2016-06-01

Many families rely on formal day care provision, which can be problematic when children are unwell. Attendance in these circumstances may impact on the transmission of infections in both day care and the wider community. Thirty-one semi-structured interviews were conducted to investigate how parents make decisions about nursery care when children are unwell. Topics for discussion included: illness attitudes, current practice during childhood illness and potential nursery policy changes that could affect decision-making. A combination of illness perceptions and external factors affected decision-making. Parents: (i) considered the severity of respiratory and non-respiratory symptoms differently, and stated that while most other contagious illnesses required nursery exclusion, coughs/colds did not; (ii) said decisions were not solely based on nursery policy, but on practical challenges such as work absences, financial penalties and alternative care availability; (iii) identified modifiable nursery policy factors that could potentially help parents keep unwell children at home, potentially reducing transmission of infectious illness. Decision-making is a complex interaction between the child's illness, personal circumstance and nursery policy. Improving our understanding of the modifiable aspects of nursery policies and the extent to which these factors affect decision-making could inform the design and implementation of interventions to reduce the transmission of infectious illness and the associated burden on NHS services. © The Author 2015.

Full Text Available The article analyzes "nursery English" in its substandard manifestations. It aims at classifying lexical units of the chosen colloquial area. Grouping the words is based on the comparison of neutral patterns and their specific ('nursery' counterparts. The results of the analysis demonstrate the two main tendencies of the language – redundancy and insufficiency – in their diverse expressions on the level of lexis of the researched field. The investigation discloses the basic models of "nursery English" (the English used by children registered in fiction (A. Milne's prose and poetry have been chosen for the analysis. It points out the mechanisms, both, phonetic and morphological, used to create the specific nature of the language of the chosen area. The word reduction and extension is registered in the initial, medium, and final positions. Both linguistic phenomena may be caused by simplifying a complex sound structure, when a child is trying to overcome the difficulty of pronouncing the word; or they may arise in the event of eliminating or adding semantically insignificant word components, or be the consequence of insufficient knowledge of grammar. In most cases, the new formations of nursery English are quite clear to the speakers due to the context or speech situation. Yet, there appear structures which cause misunderstanding. The investigated stylistic area overlaps the specific scope of substandard English used by grown-up speakers; however, certain samples of the first one may be regarded as strictly "nursery". It is not unlikely that the expansion of the researched resource will reveal other transformations. The findings can benefit the studies of English stylistics and English Language System studies.

Goshin, Lorie S.; Byrne, Mary W.; Blanchard-Lewis, Barbara

2015-01-01

This study examined long-term outcomes of children who spent their first one to eighteen months in a US prison nursery. Behavioral development in 47 preschool children who lived in a prison nursery was compared with 64 children from a large national dataset who were separated from their mothers because of incarceration. Separation was associated with significantly worse anxious/depressed scores, even after controlling for risks in the caregiving environment. Findings suggest that prison nursery co-residence with developmental support confers some resilience in children who experience early maternal incarceration. Co-residence programs should be promoted as a best practice for incarcerated childbearing women. PMID:26609188

Residents of the Red River Delta region of northern Vietnam have a long tradition of eating raw fish. Fish-borne zoonotic trematodes (FZTs) are estimated to infect ≈1 million persons in Vietnam. It remains uncertain at what stages in the aquaculture production cycle fish become infected with FZTs. Newly hatched fish (fry) from 8 hatcheries and juveniles from 27 nurseries were therefore examined for FZT infection. No FZTs were found in fry from hatcheries. In nurseries, FZT prevalence in juveniles was 14.1%, 48.6%, and 57.8% after 1 week, 4 weeks, and when overwintered in ponds, respectively. FZT prevalence was higher in grass carp (paquaculture management practices, particularly in nurseries, to minimize the risk of distributing infected juveniles to grow-out ponds and, subsequently, to markets for human consumption.

2010-11-01

One of the present concerns of fish biologists involves defining and identifying nursery habitats in the context of conservation and resource management strategies. Fish nursery studies usually report upon nursery occupation during the latter juvenile stages, despite the fact that recruitment to nurseries can start early in life, during the larval phase. Here we investigated the use of a temperate estuarine nursery area, the Lima estuary (NW Portugal), by initial development stages of flatfish species before and after metamorphosis, integrating the larval and juvenile phases. The Lima estuarine flatfish community comprised twelve taxa, seven of which were present as pelagic larvae, six as juveniles and three as adults. There was a general trend of increasing spring-summer abundance of both larvae and juveniles, followed by a sharp winter decrease, mainly of larval flatfishes. The Lima estuary was used by Solea senegalensis, Platichthys flesus and Solea solea as a nursery area, with direct settlement for the two first species. In contrast, indirect settlement was suggested for S. solea, with metamorphosis occurring outside the estuarine area. Estuarine recruitment of S. senegalensis varied between years, with young larvae occurring in the estuary throughout a prolonged period that lasted 6-9 months, corroborating the protracted spawning season. P. flesus, the second most abundant species, exhibited a typical spring estuarine recruitment, without inter-annual variations. Developed larvae arrived in the estuary during spring, whereas the 0-group juveniles emerged in the following summer period. The present study contributes new insight to our understanding of the economically important S. senegalensis, and highlights the importance of integrating the planktonic larval phase into traditional flatfish nursery studies.

The risk of nosocomial infection due to Staphylococcus aureus in fullterm newborns is higher under hospital conditions where there are overcrowded nurseries and inadequate infection control techniques. We report on an outbreak of skin infection in a Maternity Nursery (May 21, 2000) and the measures undertaken to bring the epidemic under control. These measures included: separating neonates already present in the nursery on August 23, 2000 from ones newly arriving by creating two different cohorts, one of neonates born before this date and one of neonates born later; restricting healthcare workers caring for S. aureus- infected infants from working with non-infected infants; disallowing carrier healthcare workers from caring for patients; introducing contact and droplet precautions (including the routine use of gowns, gloves, and mask); ensuring appropriate disinfection of potential sources of contamination. A representative number of isolates were typed by genomic DNA restriction length polymorphism analysis by means of pulsed-field gel electrophoresis (PFGE). Among the 227 cases of skin lesions, microbiological laboratory analyses confirmed that 175 were staphylococcal infections. The outbreak showed a gradual reduction in magnitude when the overcrowding of the Nursery was reduced by separating the newborns into the two different Nurseries (two cohorts). The genotyping of the strains by PFGE confirmed the nurse-to-newborn transmission of S. aureus. The measures adopted for controlling the S. aureus outbreak can, in retrospect, be assessed to have been very effective.

Radioactive 32P fertilizing experiment in a vegetative tea nursery

International Nuclear Information System (INIS)

Darmawijaya, M.I.

1979-01-01

To support the Indonesian tea replanting programme, Vegetative Propagation (VP) clonal tea plants of a high-yielding and high-quality variety are prepared. For a quick start of growth in the nursery and eventual good crop, the soils filled into polythene sleeves should have optimum conditions for rooting. The VP nursery manuring recommendation in Indonesia is 135 g N+72 g P 2 O 5 +70 g K 2 O per cubic metre of topsoil. Uptake of phosphorus by young VP tea plants in the nursery was studied by using 32 P-labelled superphosphate. A specific activity of 0.3 mCi/g (11 MBq/g) P 2 O 2 was still detectable 12 weeks after treatment of manuring. The laboratory analytical data proved that the P-fertilizer utilization by young VP tea plant was less than 1%. The best time for P-fertilizer application was the time of planting. It seems that the P uptake in the VP tea nursery starts with the early growth of the tea cutting. To increase the efficiency of P manuring in relation to the slower and lesser phosphate adsorption by the young VP tea plants, the best application is effected at 10 cm depth of soil. Mixing P fertilizers with soil also gives higher uptake of fertilizer P. So tea plants can use phosphate efficiently when placed as close to active roots as possible. (author)

Establishing nursery estuary otolith geochemical tags for Sea Bass (Dicentrarchus labrax): Is temporal stability estuary dependent?

Science.gov (United States)

Ryan, Diarmuid; Wögerbauer, Ciara; Roche, William

2016-12-01

The ability to determine connectivity between juveniles in nursery estuaries and adult populations is an important tool for fisheries management. Otoliths of juvenile fish contain geochemical tags, which reflect the variation in estuarine elemental chemistry, and allow discrimination of their natal and/or nursery estuaries. These tags can be used to investigate connectivity patterns between juveniles and adults. However, inter-annual variability of geochemical tags may limit the accuracy of nursery origin determinations. Otolith elemental composition was used to assign a single cohort of 0-group sea bass Dicentrarchus labrax to their nursery estuary thus establishing an initial baseline for stocks in waters around Ireland. Using a standard LDFA model, high classification accuracies to nursery sites (80-88%) were obtained. Temporal stability of otolith geochemical tags was also investigated to assess if annual sampling is required for connectivity studies. Geochemical tag stability was found to be strongly estuary dependent.

Connectivity is a critical property of marine populations, particularly for species with segregated juvenile and adult habitats. Knowledge of this link is fundamental in understanding population structure and dynamics. Young adults of commercially important fish species Solea solea, Solea senegalensis, Platichthys flesus, Diplodus vulgaris and Dicentrarchus labrax were sampled off the Portuguese coast in order to establish preliminary evidence of estuarine nursery origins through otolith elemental fingerprints. Concentrations of Li, Na, Mg, K, Mn, Cu, Zn, Sr, Ba and Pb in the otolith section corresponding to juvenile's nursery life period were determined through laser ablation inductively coupled plasma mass spectrometry. Element: Ca ratios in coastal fish differed significantly amongst collection areas, except for Platichthys flesus, and were compared with the elemental fingerprints previously defined for age 0 juveniles in the main estuarine nurseries of the Portuguese coast. Identification of nursery estuaries was achieved for four of the species. Assigned nursery origins varied amongst species and differences in the spatial scale of fish dispersal were also found. Diplodus vulgaris was not reliably assigned to any of the defined nurseries. Overall, results give evidence of the applicability of estuarine habitat tags in future assessments of estuarine nursery role. Research developments on the links between juvenile and adult habitats should contribute for the integrated management and conservation of nurseries and coastal stocks.

Full Text Available Given that nursery is a peculiar environment, the amount of nutrients removed by nursery trees represents a fundamental acquisition to optimise fertilisation strategies, with economic and environmental implications. In this context, we determined nutrient removal by apple, pear and cherry nursery trees at the end of the nursery growing cycle. We randomly removed 5 leafless apple (Golden Delicious/EMLA M9; density of 30,000 trees ha–1, pear (Santa Maria/Adams; density of 30,000 trees ha–1 and cherry (AlexTM/Gisela 6®; density of 40,000 trees ha–1 trees from a commercial nursery. Trees were divided into roots (below the root collar, rootstock (above-ground wood between root collar and grafting point and variety (1-year-old wood above the grafting point. For each organ we determined biomass, macro- (N, P, K, Ca, Mg, S, and micro- (Fe, Mn, Zn, Cu, and B nutrient concentration. Pear trees were the most developed (650 g (dw tree–1, equal to 1.75 and 2.78 folds than apple and cherry trees, respectively whereas, independently of the species, variety mostly contributed (>50% to the total tree biomass, followed by roots and then above-ground rootstock. However, the dry biomass and nutrient amount measured in rootstocks (including roots represent the cumulative amount of 2 and 3 seasons, for Gisela® 6 (tissue culture and pome fruit species (generated by mound layering, respectively.

Mangroves and seagrass beds have long been perceived as important nurseries for many fish species. While there is growing evidence from the Western Atlantic that mangrove habitats are intricately connected to coral reefs through ontogenetic fish migrations, there is an ongoing debate of the value of these coastal ecosystems in the Indo-Pacific. The present study used natural tags, viz. otolith stable carbon and oxygen isotopes, to investigate for the first time the degree to which multiple tropical juvenile habitats subsidize coral reef fish populations in the Indo Pacific (Tanzania). Otoliths of three reef fish species (Lethrinus harak, L. lentjan and Lutjanus fulviflamma) were collected in mangrove, seagrass and coral reef habitats and analyzed for stable isotope ratios in the juvenile and adult otolith zones. δ(13)C signatures were significantly depleted in the juvenile compared to the adult zones, indicative of different habitat use through ontogeny. Maximum likelihood analysis identified that 82% of adult reef L. harak had resided in either mangrove (29%) or seagrass (53%) or reef (18%) habitats as juveniles. Of adult L. fulviflamma caught from offshore reefs, 99% had passed through mangroves habitats as juveniles. In contrast, L. lentjan adults originated predominantly from coral reefs (65-72%) as opposed to inshore vegetated habitats (28-35%). This study presents conclusive evidence for a nursery role of Indo-Pacific mangrove habitats for reef fish populations. It shows that intertidal habitats that are only temporarily available can form an important juvenile habitat for some species, and that reef fish populations are often replenished by multiple coastal habitats. Maintaining connectivity between inshore vegetated habitats and coral reefs, and conserving habitat mosaics rather than single nursery habitats, is a major priority for the sustainability of various Indo Pacific fish populations.

Full Text Available Documenting how socio-ecosystem conservation knowledge and practice arise and are modified are issues of ethnobiological interest. In the Barranca de Metztitlán Biosphere Reserve (RBBM, plant nurseries, some of which were created as Environmental Management Units (UMAs, have been established to grow and conserve cacti. This paper describes these nurseries, their role in cactus conservation, and the benefits and limitations for the people managing them. The nurseries have helped decrease illegal traffic in cacti and have enabled ex situ conservation of 22 cacti species. Cactus management has changed from extraction to cultivation, as a result of the knowledge and actions of multiple actors. The main limitation is marketing, a recurring problem for non-timber forest products (NTFP. Greater coordination among stakeholders is recommended, such as involvement by non-governmental organizations to improve their probability of success, as well as learning from the experience of other cactus UMAs. Improving the market for cacti is an issue that needs an immediate solution; otherwise conservation efforts could relapse.

Paudel, Krishna P.; Pandit, Mahesh; Hinson, Roger

2016-02-01

We examine irrigation water sources and irrigation methods used by U.S. nursery plant producers using nested multinomial fractional regression models. We use data collected from the National Nursery Survey (2009) to identify effects of different firm and sales characteristics on the fraction of water sources and irrigation methods used. We find that regions, sales of plants types, farm income, and farm age have significant roles in what water source is used. Given the fraction of alternative water sources used, results indicated that use of computer, annual sales, region, and the number of IPM practices adopted play an important role in the choice of irrigation method. Based on the findings from this study, government can provide subsidies to nursery producers in water deficit regions to adopt drip irrigation method or use recycled water or combination of both. Additionally, encouraging farmers to adopt IPM may enhance the use of drip irrigation and recycled water in nursery plant production.

Almost an iceberg 'nursery,' icebergs continue to break away from the Ross Ice Shelf in Antarctica. This image from the MODerate-resolution Imaging Spectroradiometer (MODIS) aboard the Terra spacecraft, shows the level of activity along the shelf near Ross Island on September 21, 2000. The B-15 fragments are remnants of the huge iceberg (nearly 4,250 sqare miles) which broke away from the Antarctic shelf in late March 2000. Slightly visible is the line where iceberg B-20 broke away from the shelf in the last week of September. Cracks in the Antarctic ice shelf are closely observed by satellite and are of interest to scientists studying the potential effects of global warming. This true-color image was produced using MODIS bands 1, 3, and 4. Image by Brian Montgomery, NASA GSFC; data courtesy MODIS Science Team

Defining fish nursery habitats: an application of otolith elemental fingerprinting in Tampa Bay, Florida

Ley, Janet A.; McIvor, Carole C.; Peebles, Ernst B; Rolls, Holly; Cooper, Suzanne T.

2009-01-01

Fishing in Tampa Bay enhances the quality of life of the area's residents and visitors. However, people's desire to settle along the Bay's shorelines and tributaries has been detrimental to the very habitat believed to be crucial to prime target fishery species. Common snook (Centropomus undecimalis) and red drum (Sciaenops ocellatus) are part of the suite of estuarine fishes that 1) are economically or ecologically prominent, and 2) have complex life cycles involving movement between open coastal waters and estuarine nursery habitats, including nursery habitats that are located within upstream, low-salinity portions of the Bay?s tidal tributaries. We are using an emerging microchemical technique -- elemental fingerprinting of fish otoliths -- to determine the degree to which specific estuarine locations contribute to adult fished populations in Tampa Bay. In ongoing monitoring surveys, over 1,000 young-of-the-year common snook and red drum have already been collected from selected Tampa Bay tributaries. Using laser ablation-inductively coupled plasma - mass spectrometry (LA-ICP-MS), we are currently processing a subsample of these archived otoliths to identify location-specific fingerprints based on elemental microchemistry. We will then analyze older fish from the local fishery in order to match them to their probable nursery areas, as defined by young-of-the-year otoliths. We expect to find that some particularly favorable nursery locations contribute disproportionately to the fished population. In contrast, other nursery areas may be degraded, or act as 'sinks', thereby decreasing their contribution to the fish population. Habitat managers can direct strategic efforts to protect any nursery locations that are found to be of prime importance in contributing to adult stocks.

Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these concerns, a total of 115 isolates of three Pythium species (P. irregulare, P. sylvaticum, and P. ultimum) were examined at three forest nurseries using simple sequence repeat (SSR) and amplified fragment length polymorphism (AFLP) markers. Analyses revealed distinct patterns of intraspecific variation for the three species. P. sylvaticum exhibited the most diversity, followed by P. irregulare, while substantial clonality was found in P. ultimum. For both P. irregulare and P. sylvaticum, but not P. ultimum, there was evidence for significant variation among nurseries. However, all three species also exhibited at least two distinct lineages not associated with the nursery of origin. Finally, evidence was found that certain lineages and clonal genotypes, including fungicide-resistant isolates, are shared among nurseries, indicating that pathogen movement has occurred.

The rising number of children in daycare nurseries increases opportunities for the transmission of infectious diseases. Pathogens may be transmitted directly from child to child via sneezing, coughing and touching, or indirectly via the environment. Toys are among the fomites with the highest pathogen load, but their role in disease transmission is unknown. To determine if washing and disinfection of toys can reduce sickness absence and microbial pathogen load in the nursery environment. Twelve nurseries (caring for 587 children) were randomized to intervention and control groups. The intervention consisted of washing and disinfection of toys and linen every two weeks for three months by a commercial cleaning company. The extent and causes of sickness absence among the children were recorded in both groups before and after introduction of the intervention. Ten sampling points in each nursery were examined for bacteria and respiratory viruses. The presence of respiratory virus DNA/RNA was widespread, but very few pathogenic bacteria were found in the environment. The intervention reduced the presence of adenovirus [odds ratio (OR) 2.4, 95% confidence interval (CI) 1.1-5.0], rhinovirus (OR 5.3, 95% CI 2.3-12.4) and respiratory syncytial virus (OR 4.1, 95% CI 1.5-11.2) compared with the control group, but the intervention had no effect on sickness absence or disease patterns in the nurseries. Although cleaning and disinfection of toys every two weeks can decrease the microbial load in nurseries, it does not appear to reduce sickness absence among nursery children.

Coastal nursery habitats are essential for the renewal of adult fish populations. We quantified the availability of a coastal nursery habitat (shallow heterogeneous rocky bottoms) and the spatial variability of its juvenile fish populations along 250km of the Catalan coastline (France and Spain). Nurseries were present in 27% of the coastline, but only 2% of them benefited from strict protection status. For nine taxa characteristic of this habitat, total juvenile densities varied significantly between nursery sites along the coastline, with the highest densities being found on the northern sites. Recruitment level (i.e. a proxy of nursery value) was not explained by protection level, but it was moderately and positively correlated with an anthropization index. Patterns of spatial variations were taxa-specific. Exceptional observations of four juveniles of the protected grouper Epinephelus marginatus were recorded. Our data on habitat availability and recruitment levels provides important informations which help to focus MPA management efforts. Copyright © 2017 Elsevier Ltd. All rights reserved.

Coastal ecosystems provide numerous important ecological services, including maintenance of biodiversity and nursery grounds for many fish species of ecological and economic importance. However, human population growth has led to increased pollution, ocean warming, hypoxia, and habitat alteration that threaten ecosystem services. In this study, we used long-term datasets of fish abundance, water quality, and climatic factors to assess the threat of hypoxia and the regulating effects of climate on fish diversity and nursery conditions in Elkhorn Slough, a highly eutrophic estuary in central California (United States), which also serves as a biodiversity hot spot and critical nursery grounds for offshore fisheries in a broader region. We found that hypoxic conditions had strong negative effects on extent of suitable fish habitat, fish species richness, and abundance of the two most common flatfish species, English sole (Parophrys vetulus) and speckled sanddab (Citharichthys stigmaeus). The estuary serves as an important nursery ground for English sole, making this species vulnerable to anthropogenic threats. We determined that estuarine hypoxia was associated with significant declines in English sole nursery habitat, with cascading effects on recruitment to the offshore adult population and fishery, indicating that human land use activities can indirectly affect offshore fisheries. Estuarine hypoxic conditions varied spatially and temporally and were alleviated by strengthening of El Niño conditions through indirect pathways, a consistent result in most estuaries across the northeast Pacific. These results demonstrate that changes to coastal land use and climate can fundamentally alter the diversity and functioning of coastal nurseries and their adjacent ocean ecosystems. PMID:26056293

Ancient nursery area for the extinct giant shark megalodon from the Miocene of Panama.

Directory of Open Access Journals (Sweden)

Catalina Pimiento

Full Text Available BACKGROUND: As we know from modern species, nursery areas are essential shark habitats for vulnerable young. Nurseries are typically highly productive, shallow-water habitats that are characterized by the presence of juveniles and neonates. It has been suggested that in these areas, sharks can find ample food resources and protection from predators. Based on the fossil record, we know that the extinct Carcharocles megalodon was the biggest shark that ever lived. Previous proposed paleo-nursery areas for this species were based on the anecdotal presence of juvenile fossil teeth accompanied by fossil marine mammals. We now present the first definitive evidence of ancient nurseries for C. megalodon from the late Miocene of Panama, about 10 million years ago. METHODOLOGY/PRINCIPAL FINDINGS: We collected and measured fossil shark teeth of C. megalodon, within the highly productive, shallow marine Gatun Formation from the Miocene of Panama. Surprisingly, and in contrast to other fossil accumulations, the majority of the teeth from Gatun are very small. Here we compare the tooth sizes from the Gatun with specimens from different, but analogous localities. In addition we calculate the total length of the individuals found in Gatun. These comparisons and estimates suggest that the small size of Gatun's C. megalodon is neither related to a small population of this species nor the tooth position within the jaw. Thus, the individuals from Gatun were mostly juveniles and neonates, with estimated body lengths between 2 and 10.5 meters. CONCLUSIONS/SIGNIFICANCE: We propose that the Miocene Gatun Formation represents the first documented paleo-nursery area for C. megalodon from the Neotropics, and one of the few recorded in the fossil record for an extinct selachian. We therefore show that sharks have used nursery areas at least for 10 millions of years as an adaptive strategy during their life histories.

2009-05-01

Full Text Available Previous surveys conducted in commercial nurseries found that different wood fungi, namely Cylindrocarpon spp., Botryosphaeriaceae, Phomopsis viticola and Phaeomoniella chlamydospora infect grapevine cuttings. Two field trials were carried out to evaluate the effectiveness of cyprodinil + fludioxonil, pyraclostrobin + metiram, fludioxonil and cyprodinil to prevent or reduce natural infections caused by such fungi. Rootstock and scion cuttings were soaked in fungicidal suspensions for 50 min prior to grafting. After callusing, the grafted cuttings were planted in two commercial field nurseries with and without a previous history of grapevine cultivation. After nine months in the nursery, the plants were uprooted and analysed for the incidence and severity of the wood fungi. Plants uprooted from the field without a previous history of grapevine cultivation were generally less strongly infected by wood fungi. Under this condition, only the mixture cyprodinil + fludioxonil simultaneously reduced the incidence of Cylindrocarpon and Botryosphaeriaceae fungi, as well as the severity of Cylindrocarpon infections. Treatments did not produce significant differences in the incidence and severity of P. viticola, and Pa. chlamydospora. For plants grown in the field with a grapevine history, all fungicides except cyprodinil significantly reduced the incidence and severity of Cylindrocarpon fungi. Also, the incidence and severity of Botryosphaeriaceae pathogens were significantly decreased both by cyprodinil + fludioxonil and by cyprodinil. No significant differences were noticed for P. viticola incidence and severity, and Pa. chlamydospora was not detected again. These results suggest that the practice of soaking grapevine cuttings in selected fungicides prior to grafting significantly reduces Cylindrocarpon spp. and Botryosphaeriaceae infections, thus improving the quality of planting material.

2016-10-01

Full Text Available Background Mixture models (MM can be used to describe mixed stocks considering three sets of parameters: the total number of contributing sources, their chemical baseline signatures and their mixing proportions. When all nursery sources have been previously identified and sampled for juvenile fish to produce baseline nursery-signatures, mixing proportions are the only unknown set of parameters to be estimated from the mixed-stock data. Otherwise, the number of sources, as well as some/all nursery-signatures may need to be also estimated from the mixed-stock data. Our goal was to assess bias and uncertainty in these MM parameters when estimated using unconditional maximum likelihood approaches (ML-MM, under several incomplete sampling and nursery-signature separation scenarios. Methods We used a comprehensive dataset containing otolith elemental signatures of 301 juvenile Sparus aurata, sampled in three contrasting years (2008, 2010, 2011, from four distinct nursery habitats. (Mediterranean lagoons Artificial nursery-source and mixed-stock datasets were produced considering: five different sampling scenarios where 0–4 lagoons were excluded from the nursery-source dataset and six nursery-signature separation scenarios that simulated data separated 0.5, 1.5, 2.5, 3.5, 4.5 and 5.5 standard deviations among nursery-signature centroids. Bias (BI and uncertainty (SE were computed to assess reliability for each of the three sets of MM parameters. Results Both bias and uncertainty in mixing proportion estimates were low (BI ≤ 0.14, SE ≤ 0.06 when all nursery-sources were sampled but exhibited large variability among cohorts and increased with the number of non-sampled sources up to BI = 0.24 and SE = 0.11. Bias and variability in baseline signature estimates also increased with the number of non-sampled sources, but tended to be less biased, and more uncertain than mixing proportion ones, across all sampling scenarios (BI < 0.13, SE < 0

This paper deals with the experimental investigation and analysis of the energy and environmental performance of a green roof system installed in a nursery school building in Athens. The investigation was implemented in two phases. During the first phase, an experimental investigation of the green roof system efficiency was presented and analysed, while in the second one the energy savings was examined through a mathematical approach by calculating both the cooling and heating load for the summer and winter period for the whole building as well as for its top floor. The energy performance evaluation showed a significant reduction of the building's cooling load during summer. This reduction varied for the whole building in the range of 6-49% and for its last floor in the range of 12-87%. Moreover, the influence of the green roof system in the building's heating load was found insignificant, and this can be regarded a great advantage of the system as any interference in the building shell for the reduction of cooling load leads usually to the increase of its heating load.

Menkis, Audrius; Vasaitis, Rimvydas

2011-01-01

The aims of this study were to investigate patterns of ectomycorrhizal (ECM) colonisation and community structure on nursery grown seedlings of Pinus sylvestris, spatial distribution of ECMs in the nursery plot and genetic diversity of commonly isolated ECM basidiomycete Hebeloma cavipes. One hundred seedlings were sampled in 225 m(2) area using a systematic grid design. For each seedling, 20 individual root tips were randomly collected, morphotyped, and surface sterilised for fungal isolation in pure culture. Results showed that ECM community was comprised of nine distinct morphotypes among which Thelephora terrestris (39.7%), Hebeloma sp. (17.8%) and Suillus luteus (6.1%) were the most abundant. Spatial distribution of ECMs in the nursery plot was determined by their relative abundance: even in common ECMs and random in rare ones. Fungal isolation yielded 606 pure cultures, representing 71 distinct taxa. The most commonly isolated fungi were the ascomycetes Neonectria macrodidyma (20.3%), Phialocephala fortinii (13.5%), Neonectria radicicola (6.3%) and the ECM basidiomycete H. cavipes (4.5%). Intraspecific genetic diversity within 27 H. cavipes isolates was studied using two methods: restriction digestion of the amplified intergenic spacer of nuclear ribosomal DNA and genealogical concordance of five genetic markers. Five and eight genotypes were revealed by each respective method, but both of those were largely consistent, in particular, in determining the largest genotype (A) composed of 18 isolates. Mapping positions for each H. cavipes isolate and genotype in the field showed that isolates of the A genotype covered a large part of the nursery plot. This suggests that H. cavipes is largely disseminated by vegetative means of local genotypes and that nursery cultivation practices are likely to contribute to the dissemination of this species in the forest nursery soils.

Full Text Available The work summarizes the results of the research carried out by the team of forest nurseries at Sustainable Forest Management Group in Pinar del Río University Forest Research Centre in the last 25 years. The characteristics of seedlings quality are presented, the best growing media, the water management to harden the forest species under the ecological conditions of more and more lingering periods of drought. The studied forest species were: Talipariti elatum (Sw. Fryxell, Pinus tropicalis Morelet , Swietenia mahagon(L.Jacq. Swietenia macrophylla King, Caesalpinia violacea (Mill. Stand, Genipa americana L, Gerascanthus gerascanthoides (Kunth Borhidi y Cedrela odorata L. y Eucalyptus grandis Hill ex Maiden. The main results can be summarized in the following way: the size of the containers oscillates between 90 and 300 cubic centimeters; the growing media combines organic and composted components fundamentally of Pinus caribaea and Eucalyptus ssp bark., with proportions that they vary according to the species and the disposability of these components in the nurseries where the plants take place; for the water management hardening procedures were used by watering in last month of the cultivation. In general the economic analyses demonstrated the decrease of the production costs for seedlings with the employment of this novel technology, the same as their advantages on the traditional technology of seedlings production in polybags: humanization of manpower work in forest nursery, reduction of costs production, improvement of produced seedling quality and productivity increase of their workers.

Placoderm Assemblage from the Tetrapod-Bearing Locality of Strud (Belgium, Upper Famennian) Provides Evidence for a Fish Nursery

Science.gov (United States)

Clément, Gaël; Daeschler, Edward B.; Dupret, Vincent

2016-01-01

The placoderm fauna of the upper Famennian tetrapod-bearing locality of Strud, Belgium, includes the antiarch Grossilepis rikiki, the arthrodire groenlandaspidid Turrisaspis strudensis and the phyllolepidid Phyllolepis undulata. Based on morphological and morphometric evidence, the placoderm specimens from Strud are predominantly recognised as immature specimens and this locality as representing a placoderm nursery. The Strud depositional environment corresponds to a channel in an alluvial plain, and the presence of a nursery in such environment could have provided nutrients and protection to the placoderm offspring. This represents one of the earliest pieces of evidence for this sort of habitat partitioning in vertebrate history, with adults living more distantly from the nursery and using the nursery only to spawn or give live birth.

The "Jackson Nursery", existing from February 1937 until March 1938, was directed by Anna Freud and financed by Edith Jackson and Dorothy Burlingham. It took care of infants from the poorest strata of Vienna and also gave material support to their families. On the other hand, it was a training institution for psychoanalysts, offering the opportunity of observing children during their first two years, e. g. their feeding habits and social sense. In addition, the Jackson Nursery was a place for research where psychoanalytic theories of infantile development were checked against the findings of direct observation. The work started here was then continued by A. Freud and D. Burlingham on a larger scale in their War Nurseries.--This paper examines the many-sided activities in the nursery mainly on the basis of unpu blished archival documents.

Brassinosteroid is identified as an important hormone. However, information about brassinosteroid has not been fully elucidated, and few studies concerned its role in apple. The aim of this work was to study the role of brassinosteroid for apple tree growth. In our study, the effect of brassinosteroid on apple nursery tree was analyzed. The biomass, cell size and xylem content of apple nursery tree were obviously evaluated by brassinosteroid treatment; mineral elements contents, photosynthesis indexes, carbohydrate level and hormone contents were significantly high in brassinosteroid treated trees. To explore the molecular mechanisms of these phenotypic differences, iTRAQ-based quantitative proteomics were used to identify the expression profiles of proteins in apple nursery tree shoot tips in response to brassinosteroid at a key period (14days after brassinosteroid treatment). A total of 175 differentially expressed proteins were identified. They were mainly involved in chlorophyII biosynthesis, photosynthesis, carbohydrate metabolism, glycolysis, citric acid cycle, respiratory action, hormone signal, cell growth and ligin metabolism. The findings in this study indicate that brassinosteroid mediating apple nursery tree growth may be mainly through energy metabolism. Important biological processes identified here can be useful theoretical basis and provide new insights into the molecular mechanisms of brassinosteroid. Brassinosteroid is very important for plant growth and development. However, the molecular mechanism of brassinosteroid mediating growth process is not perfectly clear in plant, especially in apple nursery tree. We used a combination of physiological and bioinformatics analysis to investigate the effects of brassinosteroid on apple nursery tree growth and development. The data reported here demonstrated that brassinosteroid regulates apple nursery tree growth mainly through energy metabolism. Therefore it can provide a theoretical basis from energy

Based on the fossil record, we know that the extinct Carcharocles megalodon was the biggest shark that ever lived. Previous proposed paleo-nurser...

An empirical test of the 'shark nursery area concept' in Texas bays using a long-term fisheries-independent data set

Science.gov (United States)

Froeschke, John T.; Stunz, Gregory W.; Sterba-Boatwright, Blair; Wildhaber, Mark L.

2010-01-01

Using a long-term fisheries-independent data set, we tested the 'shark nursery area concept' proposed by Heupel et al. (2007) with the suggested working assumptions that a shark nursery habitat would: (1) have an abundance of immature sharks greater than the mean abundance across all habitats where they occur; (2) be used by sharks repeatedly through time (years); and (3) see immature sharks remaining within the habitat for extended periods of time. We tested this concept using young-of-the-year (age 0) and juvenile (age 1+ yr) bull sharks Carcharhinus leucas from gill-net surveys conducted in Texas bays from 1976 to 2006 to estimate the potential nursery function of 9 coastal bays. Of the 9 bay systems considered as potential nursery habitat, only Matagorda Bay satisfied all 3 criteria for young-of-the-year bull sharks. Both Matagorda and San Antonio Bays met the criteria for juvenile bull sharks. Through these analyses we examined the utility of this approach for characterizing nursery areas and we also describe some practical considerations, such as the influence of the temporal or spatial scales considered when applying the nursery role concept to shark populations.

Full Text Available African and Afro-brazilian literature are rising in national educational practice mainly after the publication of the Laws 10.639/03 and 11.645/08 turning mandatory the teaching of African, Afro-arazilian and indigenous history and culture, offering the opportunity to treat racial ethnic relationships in basic education. The article aims to present a reflection based on the results of a weekly pedagogical practice, approaching the education of the racial ethnic relationships through African and Afro-brazilian infantile literature in a classroom of "maternal I" (2 and 3 year old children of a nursery school. Based on a qualitative approach, this research used the method of participant research with the elaboration of a research report. The observation registers in the report allowed us to confirm the resistence to treat racial questions in scholar space. It was also possible to verify that African and Afro-brazilian literatures are substitutes for some literatures that affirm and fortify the myth of racial democracy and are, therefore, obstacles for the laws 10.639/03 and 11.645/08 in schools of basic education.

2012-12-01

This project aimed to improve hand hygiene practice during diaper changing among nurses working in the nursery. This project was conducted in one of the nurseries in a 935-bed acute care hospital with a sample of 15 nurses. A pre- and post-intervention audit was conducted utilising the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice module. A revised written workflow, which specified the occasions and process for hand hygiene during diaper changing, was introduced. Modifications to the baby bassinets and nursery were made after barriers to good hand hygiene were identified. The project was carried out over 4 months, from March to June 2011. The post-intervention audit results show an improvement in performing hand washing after changing diapers (20%) and performing the correct steps of hand rubbing (25%). However, the compliance rates decreased for the other criteria that measured whether hand rubbing or hand washing was performed prior to contacting the infant and after wrapping the infant, and whether hand washing was performed correctly. The improvement in compliance with hand washing--the main focus of the new workflow--after changing diapers was especially significant. The results indicated that having a workflow on the occasions and process for hand hygiene during diaper changing was useful in standardising practice. Pre- and post-implementation audits were effective methods for evaluating the effect of translating evidence into practice. However, this project had limited success in improving compliance with hand hygiene. This suggested that more effort is needed to reinforce the importance of hand hygiene and compliance to the proposed workflow. In addition, this project showed that for change to take place successfully, environmental modifications, increased awareness and adequate communication to every staff member are essential. © 2012 The Authors.

Brunelli, Rebecca L; Blake, Jennifer; Willits, Neil; Rommeck, Ina; McCowan, Brenda

2014-01-01

Nursery-reared infants have several behavioral and physiologic differences from their mother-reared counterparts. We investigated whether a response-contingent surrogate mitigated some of those differences by decreasing fearfulness and partner-clinging and increasing environmental exploration in nursery-reared infants continuously paired with a peer. Six nursery-reared infant rhesus macaques (in pairs) were given a mechanical responsive surrogate (RS), and 6 (in pairs) were given an identical but nonresponsive surrogate (NRS). The 2 treatment groups were compared and then combined into a single group of all 12 of surrogate-exposed animals (CS) that was compared with a nonsurrogate control group (NS) of 10 nursery-reared infants. Results showed significant differences between CS and NS infants but no significant differences between the RS and NRS infants. As compared with NS infants, CS infants showed less partner-clinging, less affiliation directed toward only partner, and more foraging and tactile–oral exploration of the environment. These advantageous effects support additional research to develop improved surrogate and the implementation of surrogate programs for nursery-reared infants. PMID:25255068

Atlantic Cod (Gadus morhua benefits from the availability of seagrass (Zostera marina nursery habitat

Directory of Open Access Journals (Sweden)

Richard J. Lilley

2014-12-01

Full Text Available The Atlantic cod (Gadus morhua is a species of significant economic and historic importance but infamous for its decline. Apart from overfishing, the causes of this decline and its subsequent lack of recovery remain largely unresolved. Indeed, the degree to which specific habitats are important for this species remains unquantified at the scale of North Atlantic. Here, the literature on the role of eelgrass meadows (Zostera marina as valuable nursery habitat for the Atlantic cod is reviewed and synthesized. Evidence is presented on relative densities of Atlantic cod in shallow water environments and in eelgrass meadows in comparison to alternative habitats. In addition, evidence pertaining to the ’viability gains’ attributed to the use of eelgrass meadows as nursery habitat (growth and survival by juvenile Atlantic cod is analyzed. Although juvenile Atlantic cod use of Z. marina is found to be facultative, when possible, available literatures indicates that they may select Z. marina as a nursery habitat where they are found in high density (average of at least 246 ha−1. From their use of Z. marina habitat the juvenile Atlantic cod receives viability benefits from it, improving their chances of reaching maturation. This paper provides strong evidence that eelgrass meadows are of significant importance to contributing to Atlantic cod stocks.

Full Text Available Background Abnormalities of external genitalia in male children nurseries and inguinal hernia are the most common congenital disorders in children. We aimed to determine prevalence rate of inguinal hernia and other genital among children nurseries, in Shahrood-Iran. Materials and Methods In this descriptive cross-sectional study, we examined 920 children nurseries boys. Physical examination of children was performed in presence of a parent in a warm room in supine and upright position with and without Valsalva maneuver. A written consent was obtained from parents before examination. Past medical history and history of surgery on inguinal and genital area was taken. Examination was performed 2 interns who were trained about genital system examination.   Results A total of 920 children nurseries boys aged 3 to 6 years were examined which were detected in 88 children and prevalence rate of these abnormalities were 9.6%. The prevalence of abnormalities in the children under study were as follows: Inguinal hernia (5.1%, cryptorchidism (2.1%, Hydrocele (1.5%, hypospadias (0.4%, Varicocele (0.1%, micropenis (0.4%. Conclusion Regarding to relatively high prevalence rate of these abnormalities and low level of people knowledge, seem screening systems for diagnosis and appropriate treatment of these abnormalities to be necessary.

Sousa, Nadine R; Franco, Albina R; Oliveira, Rui S; Castro, Paula M L

2012-03-01

Addition of fertilisers is a common practice in nursery production of conifer seedlings. The aim of this study was to evaluate whether ectomycorrhizal (ECM) fungi can be an alternative to the use of chemical fertilisers in the nursery production of Pinus pinaster. A greenhouse nursery experiment was conducted by inoculating seedlings obtained from seeds of P. pinaster plus trees with a range of compatible ECM fungi: (1) Thelephora terrestris, (2) Rhizopogon vulgaris, (3) a mixture of Pisolithus tinctorius and Scleroderma citrinum, and (4) a mixture of Suillus bovinus, Laccaria laccata and Lactarius deterrimus, using forest soil as substrate. Plant development was assessed at two levels of N-P-K fertiliser (0 or 600 mg/seedling). Inoculation with a mixture of mycelium from S. bovinus, L. laccata and L. deterrimus and with a mixture of spores of P. tinctorius and S. citrinum improved plant growth and nutrition, without the need of fertiliser. Results indicate that selected ECM fungi can be a beneficial biotechnological tool in nursery production of P. pinaster. Copyright © 2010 Elsevier Ltd. All rights reserved.

Morphological and photosynthetic adaptations of Tabebuia aurea seedlings in the nursery

Full Text Available Tabebuia aurea (Benth. & Hook. f. ex S. Moore (Bignoniaceae is a boreal species common in Brazil. It is used for ornamental parks and along sidewalks. Its timber is also used for furniture. The objective of this study was to evaluate the effect of nursery shading on the growth and photosynthesis of T. aurea and their photosynthetic adaptation after being transferred to direct sunlight. The T. aurea seedlings were grown under 0, 50, 70 or 95% shade. The photosynthetic active radiation and leaf gas exchange were measured over two distinct periods: 51 (young seedlings and 70 days after having been sown under each shade treatment. Immediately after the measurements were taken, the seedlings were transferred into full sunlight and the measurements were repeated two times after 15 min and 3 days under ambient sunlight. T. aurea seedlings showed satisfactory growth up to 50% shade in the nursery, which could be verified both by growth measurement and by total biomass accumulation. Shading greater than 70% reduced the number of leaves, the leaf area and the stem diameter in relation to plants exposed to full sunlight. The results suggest that T. aurea seedlings should be grown under full sunlight or under shading up to 50% to maximize their growth in the nursery and to minimize stress when transferring the seedlings to their final planting sites.

Compost and vermicompost as nursery pot components: effects on tomato plant growth and morphology

Energy Technology Data Exchange (ETDEWEB)

2009-07-01

Abstract Post transplant success after nursery stage is strongly influenced by plant morphology. Cultural practices strongly shape plant morphology, and substrate choice is one of the most determining factors. Peat is the most often used amendment in commercial potting substrates, involving the exploitation of non-renewable resources and the degradation of highly valuable peatland ecosystems and therefore alternative substrates are required. Here the feasibility of replacing peat by compost or vermicompost for the production of tomato plants in nurseries was investigated through the study of the effect of increasing proportions of these substrates (0%, 10%, 20%, 50%, 75% and 100%) in target plant growth and morphological features, indicators of adequate post-transplant growth and yield. Compost and vermicompost showed to be adequate substrates for tomato plant growth. Total replacement of peat by vermicompost was possible while doses of compost higher than 50% caused plant mortality. Low doses of compost (10 and 20%) and high doses of vermicompost produced significant increases in aerial and root biomass of the tomato plants. In addition these treatments improved significantly plant morphology (higher number of leaves and leaf area, and increased root volume and branching). The use of compost and vermicompost constitute an attractive alternative to the use of peat in plant nurseries due to the environmental benefits involved but also due to the observed improvement in plant quality.

Synthesis of ectomycorrhizae on northern red oak seedlings in a Michigan nursery

Energy Technology Data Exchange (ETDEWEB)

Dixon, R.K.; Johnson, P.S.

1993-01-01

Vegetative inoculum of the ectomycorrhizal fungus Suillus luteus was thoroughly mixed into fumigated nursery soil, and northern red oak seedlings of four families were evaluated one and two years after sowing for ectomycorrhizal development, growth, and nutrition. At the end of year one, treated seedlings were successfully inoculated with S. luteus, but the percentage varied significantly with family. Suillus luteus persisted on lateral roots two years following sowing. Two of four seedling families inoculated with S. luteus were significantly larger in size than control plants. These results suggest that the fungal symbiont S. luteus can be successfully introduced into nurseries and that early ectomycorrhizal development improves the growth of northern red oak seedlings.

The relative contribution of diurnal and nocturnal pollinators to plant female fitness in a specialized nursery pollination system.

Scopece, Giovanni; Campese, Lucia; Duffy, Karl J; Cozzolino, Salvatore

2018-02-01

Plants involved in specialized pollinator interactions, such as nursery pollination, may experience trade-offs in their female fitness, as the larvae of their pollinators may also consume seeds produced by the flowers they pollinate. These interactions could potentially shift between mutualism and parasitism, depending on the presence and abundance of both the nursery pollinator and of other pollinators. We investigated the fitness trade-off in a Mediterranean plant ( Silene latifolia ), which has a specialist nocturnal nursery pollinator moth ( Hadena bicruris ) and is also visited by several diurnal pollinators. We estimated the pollination rates and fecundity of S. latifolia in both natural and experimental populations in the Mediterranean. We estimated natural pollination rates in different flowering times and with presence/absence of the H. bicruis moth. Then by exposing plants to each pollinator group either during the day or at night, we quantified the contribution of other diurnal pollinators and the specialized nocturnal nursery pollinator to plant female fitness. We found no difference in plant fruit set mediated by diurnal versus nocturnal pollinators, indicating that non-specialist pollinators contribute to plant female fitness. However, in both natural and experimental populations, H. bicruris was the most efficient pollinator in terms of seeds produced per fruit. These results suggest that the female fitness costs generated by nursery pollination can be overcome through higher fertilization rates relative to predation rates, even in the presence of co-pollinators. Quantifying such interactions is important for our understanding of the selective pressures that promote highly specialized mutualisms, such as nursery pollination, in the Mediterranean region, a centre of diversification of the carnation family.

Carbon isotopes in otolith amino acids identify residency of juvenile snapper (Family: Lutjanidae) in coastal nurseries

McMahon, Kelton; Berumen, Michael L.; Mateo, Ivan; Elsdon, Travis S.; Thorrold, Simon R.

2011-01-01

This study explored the potential for otolith geochemistry in snapper (Family: Lutjanidae) to identify residency in juvenile nursery habitats with distinctive carbon isotope values. Conventional bulk otolith and muscle stable isotope analyses (SIA) and essential amino acid (AA) SIA were conducted on snapper collected from seagrass beds, mangroves, and coral reefs in the Red Sea, Caribbean Sea, and Pacific coast of Panama. While bulk stable isotope values in otoliths showed regional differences, they failed to distinguish nursery residence on local scales. Essential AA δ13C values in otoliths, on the other hand, varied as a function of habitat type and provided a better tracer of residence in different juvenile nursery habitats than conventional bulk otolith SIA alone. A strong linear relationship was found between paired otolith and muscle essential AA δ13C values regardless of species, geographic region, or habitat type, indicating that otolith AAs recorded the same dietary information as muscle AAs. Juvenile snapper in the Red Sea sheltered in mangroves but fed in seagrass beds, while snapper from the Caribbean Sea and Pacific coast of Panama showed greater reliance on mangrove-derived carbon. Furthermore, compound-specific SIA revealed that microbially recycled detrital carbon, not water-column-based new phytoplankton carbon, was the primary carbon source supporting snapper production on coastal reefs of the Red Sea. This study presented robust tracers of juvenile nursery residence that will be crucial for reconstructing ontogenetic migration patterns of fishes among coastal wetlands and coral reefs. This information is key to determining the importance of nursery habitats to coral reef fish populations and will provide valuable scientific support for the design of networked marine-protected areas. © 2011 Springer-Verlag.

2015-01-01

Nursing staff are an important source of support for parents of a hospitalized preterm infant. This study aimed to describe parents' and nurses' perceptions of communicating with each other in the context of the special care nursery. A qualitative descriptive design was employed. Thirty two parents with a newborn admitted to one of two special care nurseries in Queensland, Australia participated, and 12 nurses participated in semi-structured interviews. Thematic analysis was used to analyze the interviews. Nurses and parents focused on similar topics, but their perceptions differed. Provision of information and enabling parenting were central to effective communication, supported by an appropriate interpersonal style by nurses. Parents described difficulties accessing or engaging nurses. Managing enforcement of policies was a specific area of difficulty for both parents and nurses. The findings indicated a tension between providing family-centered care that is individualized and based on family needs and roles, and adhering to systemic nursery policies.

Recruitment and connectivity influence the role of seagrass as a penaeid nursery habitat in a wave dominated estuary.

Science.gov (United States)

Taylor, Matthew D; Fry, Brian; Becker, Alistair; Moltschaniwskyj, Natalie

2017-04-15

Estuaries provide a diverse mosaic of habitats which support both juveniles and adults of exploited species. In particular, estuaries play an important role in the early life history of many penaeid prawn species. This study used a combination of stable isotope ecology and quantitative sampling to examine recruitment and the nursery function of seagrass habitats for Eastern King Prawn (Penaeus [Melicertus] plebejus), and the processes that contributed to this nursery role. Stable isotopes were used to assign prawns joining the adult stock to putative nursery habitat areas within the estuary. Emigrating prawns originated from only 11 of the 20 sites surveyed. Of these, 8 sites were designated as Effective Juvenile Habitat (EJH), and 5 sites designated as Nursery Habitat (NH). The contribution of individuals from different nursery areas to the adult stock was related to both the abundance of prawns within an area and the distance to the mouth of the estuary, and with the exception of 1 site all EJH and NH were located in the northern section of the estuary. Quantitative sampling in this area indicated that prawns were present at an average density of 165±11 per 100m 2 , and density formed non-linear relationships with the distance to the mouth of the estuary, seagrass cover and temperature. Prawn size also formed non-linear relationships with prawn density and seagrass cover. Spatial patterns in abundance were consistent with wind-driven recruitment patterns, which in turn affected the nursery role of particular areas within the system. These findings have implications for targeted fishery restoration efforts for both Eastern King Prawn and other ocean spawned species in wave dominated estuaries where circulation is primarily wind-driven.

Hulvey, Jon; Gobena, Daniel; Finley, Ledare; Lamour, Kurt

2010-01-01

In 2008 statewide surveys of symptomatic foliage of nursery plants from Tennessee resulted in isolation of 43 isolates of Phytophthora spp. This sample set includes four described species (P. citrophthora, P. citricola, P. nicotianae, P. syringae), and a provisional species of Phytophthora ('P. hydropathica'). At the same time a stream-baiting survey was initiated to recover Phytophthora from eight watersheds in eastern Tennessee, some of which are near plant nurseries. Baiting was accomplished by submerging healthy Rhododendron leaves approximately 1 wk and isolation onto selective media. Six baiting periods were completed, and in total 98 Phytophthora isolates and 45 isolates of Pythium spp. were recovered. Three described species (P. citrophthora, P. citricola and P. irrigata) and the provisional species 'P. hydropathica' were obtained as well as three undescribed Phytophthora taxa and Pythium litorale. Isolates from both surveys were identified to species with morphology and the internal transcribed spacer (ITS) sequence. Isolates from species co-occurring in streams and nurseries (P. citricola, P. citrophthora and 'P. hydropathica') were characterized further with amplified fragment length polymorphism (AFLP) analyses and mefenoxam tolerance assays. Isolates representing a putative clonal genotype of P. citricola were obtained from both environmental and nursery sample sets.

Forest regeneration is a cyclic operation. Seeds are collected from mature trees and planted in nurseries so that the resulting seedlings can be outplanted to the forest after the mature trees are harvested. Similarly, the process of deciding upon, and growing, the best seedlings for that site should be a cyclic process between foresters and nursery managers. The ideal...

Fusarium commune can cause damping-off and root rot of conifer seedlings in forest nurseries, and this pathogen has been previously reported from Oregon, Idaho, and Washington, USA. We collected Fusarium isolates from additional nurseries in the midwestern and western USA to more fully determine occurrence of this pathogen. We used DNA sequences of the mitochondrial...

Do nursery habitats provide shelter from flow for juvenile fish?

Directory of Open Access Journals (Sweden)

Darren M Parsons

Full Text Available Juvenile fish nurseries are an essential life stage requirement for the maintenance of many fish populations. With many inshore habitats globally in decline, optimising habitat management by increasing our understanding of the relationship between juvenile fish and nursery habitats may be a prudent approach. Previous research on post-settlement snapper (Chrysophrys auratus has suggested that structure may provide a water flow refuge, allowing snapper to access high water flow sites that will also have a high flux of their pelagic prey. We investigated this hypothesis by describing how Artificial Seagrass Units (ASUs modified water flow while also using a multi-camera set up to quantify snapper position in relation to this water flow environment. Horizontal water flow was reduced on the down-current side of ASUs, but only at the height of the seagrass canopy. While the highest abundance of snapper did occur down-current of the ASUs, many snapper also occupied other locations or were too high in the water column to receive any refuge from water flow. The proportion of snapper within the water column was potentially driven by strategy to access zooplankton prey, being higher on the up-current side of ASUs and on flood tides. It is possible that post-settlement snapper alternate position to provide opportunities for both feeding and flow refuging. An alternative explanation relates to an observed interaction between post-settlement snapper and a predator, which demonstrated that snapper can utilise habitat structure when threatened. The nature of this relationship, and its overall importance in determining the value of nursery habitats to post-settlement snapper remains an elusive next step.

Vergara, Lizandra Garcia Lupi; Ribet, Lucie Elisa

2012-01-01

A study in the educators' work station at baby nursery of NDI/UFSC, located in Florianópolis, was conducted using the Work Ergonomic Analysis methodological tool. The demand considered was the educators' physical exhaustion caused by the weight carried when taking care of the babies, the postures assumed during the labor activity and the spatial arrangement of the baby nursery. Thinking ergonomically, the spatial arrangement is directly associated to three factors: the formal aspect of the environment, the esthetic aspect including colors and finish quality and the ease of understanding involved in the baby nursery labor. By the ergonomic adequacy it is possible to assert that if were established better conditions of posture and comfort for the educators, as well as satisfactory technical and operational information to carry out the activities, greater safety and welfare would be provided to the babies, the main focus of the work.

Branco, P.T.B.S.; Alvim-Ferraz, M.C.M.; Martins, F.G.; Sousa, S.I.V.

2015-01-01

Indoor air quality (IAQ) in nurseries is an emerging case-study. Thus, this study, as the Part I of the larger study “Children's exposure to indoor air in urban nurseries”, aimed to: i) evaluate nurseries’ indoor concentrations of carbon dioxide (CO 2 ), a global IAQ indicator, in class and lunch rooms; ii) assess indoor comfort parameters–temperature (T) and relative humidity (RH); and iii) analyse them according to guidelines and references for IAQ, comfort and children's health. Indoor continuous measurements were performed. Non-compliances with guidelines were found in comfort parameters, which could cause discomfort situations and also microbial proliferation. Exceedances in CO 2 concentrations were also found and they were caused by poor ventilation and high classroom occupation. More efficient ventilation and control of comfort parameters, as well as to reduce occupation by reviewing Portuguese legislation on that matter, would certainly improve IAQ and comfort in nurseries and consequently safeguard children's health. - Highlights: • High occupation and poor ventilation were main determinants of IAQ in nurseries. • T and RH indoor values found in nurseries are likely to cause thermal discomfort. • Building characteristics and an inadequate ventilation determined T and RH values. • High CO 2 concentrations found could indicate accumulation of other air pollutants

This study collected data from 467 nursery teachers and it aimed to investigate the association between mental health and emotional dissonance and job burnout of the day care nursery teachers. Measurement tool was developed, most of the questions having 5-point scale. The data were analyzed structural equation model with the statistical package IBM SPSS 23 and AMOS 21 with 5% percent of significance level. Main results are as follows. First, it was found that emotional dissonance of nursery teachers working in day care centers showed significant effect on the mental health such factors as job-stress (relationships with children and parents and work overload). Second, emotional dissonance were found to have a significant effect on job burnout, too. Third, job burnout had a significant effect on the mental health, job stress and psychological wellbeing. Fourth, job burnout was found to mediate partially on mental health and emotional dissonance. These findings suggest the importance of mental health promotion programs for child care teachers working in the day care centers.

The school canteen plays today an essential role in child nutrition and for consolidating appropriate eating habits. In Spain, the guidelines for school meals have been established by the NAOS strategy and the Perseus program, and are especially aimed at school children of 6-10 years. However, there is a lack of information on menus offered in pre-school education centres, which take in children of pre-school age. The aim of this study was to evaluate the composition and the food supplied in pre-schools of the province of Granada. A study was conducted on the menus offered in public pre-schools in Granada, with a population of 420 children aged 2-6 years old. A total of 20 menus were analysed, and details were collected including direct information on the ingredients used, the proportion of these in each dish, and the form of preparation. The daily intake of energy and nutrients, as well as the frequency of weekly supply of the different food groups were studied. The average energy content of the menus was 512.5kcal, distributed into protein (17.3%), carbohydrates (48.8%), and lipids (33.9%). A suitable supply of fibre (7.8g/day) was observed, but content of calcium and zinc did not reach recommended levels. The supply of vegetables was adequate, with a daily presence of salad, as well as vegetables, meat, fish and fruit. Menus evaluated represent an adequate content of energy, and proper supply of the different groups of foods, especially vegetables, fruits and salads. A great effort is observed in the centres to adapt meals to nutritional recommendations. Copyright © 2015 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

Perceptions of nursery staff and parent views of healthy eating promotion in preschool settings: an exploratory qualitative study.

2016-08-19

In the UK just over a fifth of all children start school overweight or obese and overweight 2-5 year olds are at least 4 times more likely to become overweight adults. This can lead to serious future health problems. The WHO have recently highlighted the preschool years as a critical time for obesity prevention, and have recommended preschools as an ideal setting for intervention. However, existing evidence suggests that the preschool environment, including the knowledge, beliefs and practices of preschool staff and parents of young children attending nurseries can be a barrier to the successful implementation of healthy eating interventions in this setting. This study examined the perceptions of preschool centre staff and parents' of preschool children of healthy eating promotion within preschool settings. The participants were preschool staff working in private and local authority preschool centres in the North East of England, and parents of preschool children aged 3-4 years. Preschool staff participated in semi-structured interviews (n = 16 female, 1 male). Parents completed a mapping activity interview (n = 14 mothers, 1 father). Thematic analysis was applied to interpret the findings. Complex communication issues surrounding preschool centre dietary 'rules' were apparent. The staff were keen to promote healthy eating to families and felt that parents needed 'education' and 'help'. The staff emphasised that school policies prohibited providing children with sugary or fatty snacks such as crisps, cakes, sweets and 'fizzy' drinks, however, some preschool centres appeared to have difficulty enforcing such guidelines. Parents were open to the idea of healthy eating promotion in preschool settings but were wary of being 'told what to do' and being thought of as 'bad parents'. There is a need to further explore nursery staff members' personal perceptions of health and how food policies which promote healthier food in preschool settings can be embedded and

Novel flow-through bioremediation system for removing nitrate from nursery discharge water.

Chris Wilson, P; Albano, Joseph P

2013-11-30

Nitrate losses in surface runoff water from nursery production areas can be significant. This study evaluated the potential use of microbial-based (denitrification), flow-through bioreactors for their nitrate-remediation ability. Duplicate bioreactor systems were constructed at a local foliage plant nursery. Each bioreactor system consisted of four 242 L tanks with connections alternating between bottom and top. Each tank was filled with approximately 113 L of Kaldness media to provide surface area for attachment of native microflora. Molasses was supplied as a carbon source for denitrification and water flow rates through the systems ranged from 5 to 18 L min(-1) during tests. Automatic water samplers were used to collect composite samples every 15 min from both the inflow and the exit flow water. Results indicate consistent removal of 80-100% of the nitrate flowing into the systems. Accumulation of ammoniacal and nitrite nitrogen did not occur, indicating that the nitrate-nitrogen was removed from the water, and not simply transformed into another water-soluble species. Occasions where removal rates were less than 80% were usually traced to faulty delivery of the carbon source. Results indicate that modular microbial-based bioremediation systems may be a useful tool for helping water managers meet stringent nitrogen water quality regulations, especially at nurseries with limited space for expansion of water retention facilities.

In this collection of papers, psychoanalytic principles come to life in a variety of settings: in a therapeutic nursery, in two schools serving children with special needs, in mainstream schools, and in a psychiatric practice. From dyadic work with a two-year-old's tantrums, to play therapy using deep-sea symbolism with a five-year-old; from the interchange with parents and school administrators in a middle school regarding "sexting, " to the in-depth assessment of children upon entry to a special school, these papers illustrate enriching exchanges between psychoanalysts, educators, children, and their communities.

2018-05-01

The use of enhanced technologies of temperature control can improve the thermal conditions in environments of livestock facilities. The objective of this study was to evaluate the spatial distribution of the thermal environment variables in a pig nursery with a heating system with two temperature control technologies based on the geostatistical analysis. The following systems were evaluated: overhead electrical resistance with Proportional, Integral, and Derivative (PID) controller and overhead electrical resistance with a thermostat. We evaluated the climatic variables: dry bulb temperature (Tbs), air relative humidity (RH), temperature and humidity index (THI), and enthalpy in the winter, at 7:00, 12:00, and 18:00 h. The spatial distribution of these variables was mapped by kriging. The results showed that the resistance heating system with PID controllers improved the thermal comfort conditions in the pig nursery in the coldest hours, maintaining the spatial distribution of the air temperature more homogeneous in the pen. During the hottest weather, neither system provided comfort.

Byrne, M W; Goshin, L S; Joestl, S S

2010-07-01

Within a larger intervention study, attachment was assessed with the Strange Situation Procedure for 30 infants who co-resided with their mothers in a prison nursery. Sixty percent of infants were classified secure, 75% who co-resided a year or more and 43% who co-resided less than a year, all within the range of normative community samples. The year-long co-residing group had significantly more secure and fewer disorganized infants than predicted by their mothers' attachment status, measured by the Adult Attachment Interview, and a significantly greater proportion of secure infants than meta-analyzed community samples of mothers with low income, depression, or drug/alcohol abuse. Using intergenerational data collected with rigorous methods, this study provides the first evidence that mothers in a prison nursery setting can raise infants who are securely attached to them at rates comparable to healthy community children, even when the mother's own internal attachment representation has been categorized as insecure.

2016-09-01

Chemical control is the method most used for management of Diaphorina citri, the vector of the phloem-limited bacteria associated with citrus huanglongbing (HLB) disease. The objectives of this study were to determine the influence of soil-drench applications of neonicotinoids (thiamethoxam and imidacloprid) on the probing behaviour of D. citri on citrus nursery trees, using the electrical penetration graph (EPG) technique, and to measure the D. citri settling behaviour after probing on citrus nursery trees that had received these neonicotinoid treatments. The drench applications of neonicotinoids on citrus nursery trees disrupt D. citri probing, mainly for EPG variables related to phloem sap ingestion, with a significant reduction (≈90%) in the duration of this activity compared with untreated plants in all assessment periods (15, 35 and 90 days after application). Moreover, both insecticides have a repellent effect on D. citri, resulting in significant dispersal of psyllids from treated plants. This study clearly demonstrates the interference of soil-applied neonicotinoids on the feeding and settling behaviour of D. citri on citrus nursery trees, mainly during the phloem ingestion phase. These findings reinforce the recommendation of drench application of neonicotinoids before planting nursery trees as a useful strategy for HLB management. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Using a spatially structured life cycle model to assess the influence of multiple stressors on an exploited coastal-nursery-dependent population

Science.gov (United States)

Archambault, B.; Rivot, E.; Savina, M.; Le Pape, O.

2018-02-01

Exploited coastal-nursery-dependent fish species are subject to various stressors occurring at specific stages of the life cycle: climate-driven variability in hydrography determines the success of the first eggs/larvae stages; coastal nursery habitat suitability controls juvenile growth and survival; and fisheries target mostly adults. A life cycle approach was used to quantify the relative influence of these stressors on the Eastern English Channel (EEC) population of the common sole (Solea solea), a coastal-nursery-dependent flatfish population which sustains important fisheries. The common sole has a complex life cycle: after eggs hatch, larvae spend several weeks drifting in open water. Survivors go on to metamorphose into benthic fish. Juveniles spend the first two years of their life in coastal and estuarine nurseries. Close to maturation, they migrate to deeper areas, where different subpopulations supplied by different nurseries reproduce and are exploited by fisheries. A spatially structured age-and stage-based hierarchical Bayesian model integrating various aspects of ecological knowledge, data sources and expert knowledge was built to quantitatively describe this complex life cycle. The model included the low connectivity among three subpopulations in the EEC, the influence of hydrographic variability, the availability of suitable juvenile habitat and fisheries. Scenarios were designed to quantify the effects of interacting stressors on population renewal. Results emphasized the importance of coastal nursery habitat availability and quality for the population renewal. Realistic restoration scenarios of the highly degraded Seine estuary produced a two-third increase in catch potential for the adjacent subpopulation. Fisheries, however, remained the main source of population depletion. Setting fishing mortality to the maximum sustainable yield led to substantial increases in biomass (+100%) and catch (+33%) at the EEC scale. The approach also showed how

Habitat quality of a subarctic nursery ground for 0-group plaice ( Pleuronectes platessa L.)

Freitas, Vânia; Campos, Joana; Skreslet, Stig; van der Veer, Henk W.

2010-07-01

Habitat quality of a subarctic nursery ground in northern Norway for 0-group plaice Pleuronectes platessa was investigated by following settlement, mortality and growth during 2005 and 2006. Newly settled individuals were first observed in the end of May to early June and settlement lasted until mid-July. Densities peaked in early July and were comparable to those reported in temperate nursery grounds. Mortality estimates after settlement differed between 0.062 d -1 in 2005 and 0.025 d -1 in 2006. Potential predators appeared to be rather similar as those reported in other areas: the brown shrimp Crangoncrangon, the shore crab Carcinus maenas and demersal fish species (gadoids). Population mean growth indicated linear growth until August leveling-off afterwards. 0-group plaice reached a lower mean size (5-6 cm) at the end of the growing season than in temperate areas probably due to later settlement timing in combination with lower summer-autumn water temperatures. The comparison of observed growth rates with predictions of maximum growth models indicated a similar pattern as observed in temperate nursery grounds: Growth appeared to be maximal except for the period after summer. Whether or not this was related to changes in food quality throughout the season, to interspecies competition or to emigration remains to be elucidated.

This study evaluated the expression of nonnutritive sucking habits and the presence of malocclusion in children using day nurseries' facilities. The 195 children (7-40 months) attending 18 public day nurseries were evaluated clinically in Ponta Grossa, Brazil. Statistical package software was used for descriptive, univariate, bivariate, and multiple logistic regressions of the data about the socioeconomic condition, educational family status, malocclusions, and prevalence of nonnutritive sucking habits among the children. The pacifier users had a statistically significant, explanatory association with open bite [odds ratio (OR) = 10.97; 95% confidence interval (CI): 4.95, 24.31; p < 0.0001]. The children older than 25 months had more open bite than younger children (OR = 6.07; 95% CI: 2.81, 13.11; p < 0.0001). Of the children examined, 35.4% had an anterior open bite, 0.51% had posterior cross-bite, and 1.03% showed finger-sucking habits. A high frequency of pacifier-sucking habits was found (52%), with a significant association between this habit and anterior open bite (p < 0.0001, OR = 7.49; 95% CI: 3.71, 15.15). The 126 children without open bite (36.5%) were pacifier users. There was suggestive, though nonsignificant, evidence of a difference in pacifier use by gender (males, 34%; females, 46%; p = 0.07). The 69 children with open bite (81.16%) were pacifier users and (18.84%) nonusers. The boys showed a slightly greater association with open bite (OR = 21.33; 95% CI: 6.12, 74.40; p < 0.0001) than girls (OR = 5.03; 95% CI: 1.26, 20.00; p = 0.02) in the age group of 25 to 40 months; however, it was not observed in younger children. Pacifier use is a predictor for open bite in children from the lower socioeconomic classes using day nurseries' facilities. The parents, guardians, and caregivers working in public day nurseries should be advised to monitor nonnutritive sucking habits in order to avoid or minimize the occurrence of malocclusion. It demonstrates that

2000-07-01

The nursery function of various biotopes for coral reef fishes was investigated on Bonaire, Netherlands Antilles. Length and abundance of 16 commercially important reef fish species were determined by means of visual censuses during the day in six different biotopes: mangrove prop-roots ( Rhizophora mangle) and seagrass beds ( Thalassia testudinum) in Lac Bay, and four depth zones on the coral reef (0 to 3 m, 3 to 5 m, 10 to 15 m and 15 to 20 m). The mangroves, seagrass beds and shallow coral reef (0 to 3 m) appeared to be the main nursery biotopes for the juveniles of the selected species. Mutual comparison between biotopes showed that the seagrass beds were the most important nursery biotope for juvenile Haemulon flavolineatum, H. sciurus, Ocyurus chrysurus, Acanthurus chirurgus and Sparisoma viride, the mangroves for juvenile Lutjanus apodus, L. griseus, Sphyraena barracuda and Chaetodon capistratus, and the shallow coral reef for juvenile H. chrysargyreum, L. mahogoni , A. bahianus and Abudefduf saxatilis. Juvenile Acanthurus coeruleus utilized all six biotopes, while juvenile H. carbonarium and Anisotremus surinamensis were not observed in any of the six biotopes. Although fishes showed a clear preference for a specific nursery biotope, most fish species utilized multiple nursery biotopes simultaneously. The almost complete absence of juveniles on the deeper reef zones indicates the high dependence of juveniles on the shallow water biotopes as a nursery. For most fish species an (partial) ontogenetic shift was observed at a particular life stage from their (shallow) nursery biotopes to the (deeper) coral reef. Cluster analyses showed that closely related species within the families Haemulidae, Lutjanidae and Acanthuridae, and the different size classes within species in most cases had a spatial separation in biotope utilization.

Colangelo, D J; Brand, M H

2001-01-01

Container production of nursery crops is intensive and a potential source of nitrogen release to the environment. This study was conducted to determine if trickle irrigation could be used by container nursery producers as an alternative to standard overhead irrigation to reduce nitrogen release into the environment. The effect of overhead irrigation and trickle irrigation on leachate nitrate N concentration, flow-weighted nitrate N concentration, leachate volume, and plant growth was investigated using containerized rhododendron (Rhododendron catawbiense Michx. 'Album') supplied with a controlled-release fertilizer and grown outdoors on top of soil-monolith lysimeters. Leachate was collected over two growing seasons and overwinter periods, and natural precipitation was allowed as a component of the system. Precipitation accounted for 69% of the water entering the overhead-irrigated system and 80% of the water entering the trickle-irrigated system. Leachate from fertilized plants exceeded the USEPA limit of 10 mg L(-1) at several times and reached a maximum of 26 mg L(-1) with trickle irrigation. Average annual loss of nitrate N in leachate for fertilized treatments was 51.8 and 60.5 kg ha(-1) for the overhead and trickle treatments, respectively. Average annual flow-weighted concentration of nitrate N in leachate of fertilized plants was 7.2 mg L(-1) for overhead irrigation and 12.7 mg L(-1) for trickle irrigation. Trickle irrigation did not reduce the amount of nitrate N leached from nursery containers when compared with overhead irrigation because precipitation nullified the potential benefits of reduced leaching fractions and irrigation inputs provided under trickle irrigation.

Full Text Available European beech (Fagus sylvatica L. is, along with its significance as a forest species, renowned as an ornamental species, due to its numerous cultivars. Ornamental beech cultivars are planted in various green spaces, but a small number of such trees have ascertained in Serbia. For the time being, production of beech cultivars is represented in a very small number of nurseries, with a negligible share of those seedlings in their total assortment. The aim of this research is to study the attitudes of ornamental trees and shrubs producers towards the nursery production of ornamental beech cultivars, and possibilities of its improvements in Serbia. “Door to door” survey and in-depth interviews were used as research techniques. Surveys with the representatives of 65 nurseries in Serbia (in the selected statistical region Šumadija and Western Serbia were conducted in the first stage of data collection. In the second stage of data collection were interviewed the representatives of the 10 nurseries who, during the survey, pointed out that they produce ornamental beech cultivars. Nurserymen’s attitudes suggest that there is a possibility to improve the production of ornamental beech cultivars in Serbia, with the appropriate support measures and increased interest of customers on the market, i.e. with the provision of subsidies for the production of seedlings and greater use of cultivars by utility companies in the cities of Serbia.

The life history strategies of sharks often include the use of protected nursery areas by young-of-the-year and juveniles. Nursery areas can be primary (i.e., grounds where the sharks are born and spend the very first part of their lives) or secondary (i.e., grounds inhabited by slightly older but not yet mature individuals). Criteria utilized to recognize these strategic habitats include: high concentration of young sharks, high food availability, and low predation risk. Since the fossil record of sharks consists mainly of isolated teeth, identification of paleonurseries involves a series of problems due to difficult application of actualistic criteria. A rich shark tooth-bearing level (ST-low1) has recently been discovered in the upper Miocene deposits of the Pisco Formation exposed at Cerro Colorado (southern coast of Peru). Most of the teeth collected from this level belong to the extant copper shark Carcharhinus brachyurus. These teeth are small and compatible with those of extant juveniles. This observation, coupled with other paleoenvironmental considerations, indicates that the ST-low1 horizon could have represented a nursery ground for juvenile individuals of C. brachyurus. The absence of very small-sized teeth (i.e., referable to young-of-the-year) suggests a secondary nursery ground inhabited by immature copper sharks. Observations on the tooth size of other Lamniformes, Carcharhiniformes, and Myliobatiformes occurring along with C. brachyurus point to a significantly juvenile structure of this elasmobranch assemblage, thus supporting the hypothesis of a communal use of the Cerro Colorado paleonursery.

Destruction and pollution of coral reefs threaten these marine biodiversity hot stops which shelter more than two thirds of sea snake species. Notably, in many coral reef ecosystems of the Western Pacific Ocean, large populations of sea kraits (amphibious sea snakes) have drastically declined during the past three decades. Protecting remaining healthy populations is thus essential. In New Caledonia, coral reefs shelter numerous sea krait colonies spread throughout an immense lagoon (24,000 km2). Sea kraits feed on coral fish but lay their eggs on land. However, ecological information on reproduction and juveniles is extremely fragmentary, precluding protection of key habitats for reproduction. Our 10 years mark recapture study on Yellow sea kraits (L. saintgironsi >8,700 individuals marked) revealed that most neonates aggregate in highly localized coastal sites, where they feed and grow during several months before dispersal. Hundreds of females emigrate seasonally from remote populations (>50 km away) to lay their eggs in these coastal nurseries, and then return home. Protecting these nurseries is a priority to maintain recruitment rate, and to retain sea krait populations in the future. PMID:24670985

2016-01-01

Full Text Available The protection of the habitats used by juvenile sharks is a management strategy that has recently caught the attention of fishery biologists. In the present study, we evaluated the population of the lemon shark (Negaprion brevirostris from Los Roques Archipelago in order to identify the nursery area, describe the size composition, and examine the variation in nocturnal activity of the juvenile individuals. The data analysed came from three different sources: commercial shark fishery, tag-recapture sampling, and visual records. A total of 375 lemon sharks with total lengths between 55 and 281 cm were recorded during the study period. Overall data showed that the area occupied by juvenile lemon sharks was clearly partitioned into primary and secondary nurseries. Additionally, nighttime activity seemed to change according to the size of sharks in the primary nursery, suggesting a reduction of time activity overlapping among juveniles of distinct size/age. Results suggest that the strategy of utilization of the primary nurseries by the lemon shark may lead to important ecological benefits by reducing the competition, predation and natural mortality.

Indoor air quality (IAQ) in nurseries is an emerging case-study. Thus, this study, as the Part I of the larger study “Children's exposure to indoor air in urban nurseries”, aimed to: i) evaluate nurseries’ indoor concentrations of carbon dioxide (CO{sub 2}), a global IAQ indicator, in class and lunch rooms; ii) assess indoor comfort parameters–temperature (T) and relative humidity (RH); and iii) analyse them according to guidelines and references for IAQ, comfort and children's health. Indoor continuous measurements were performed. Non-compliances with guidelines were found in comfort parameters, which could cause discomfort situations and also microbial proliferation. Exceedances in CO{sub 2} concentrations were also found and they were caused by poor ventilation and high classroom occupation. More efficient ventilation and control of comfort parameters, as well as to reduce occupation by reviewing Portuguese legislation on that matter, would certainly improve IAQ and comfort in nurseries and consequently safeguard children's health. - Highlights: • High occupation and poor ventilation were main determinants of IAQ in nurseries. • T and RH indoor values found in nurseries are likely to cause thermal discomfort. • Building characteristics and an inadequate ventilation determined T and RH values. • High CO{sub 2} concentrations found could indicate accumulation of other air pollutants.

Samant, S. A.; Beighley, R. E.

2007-12-01

In agriculture, improper, excessive or poorly timed irrigation and fertilizer applications can result in increased pollutants in runoff and degraded water quality. Specifically, the cultivation of salt sensitive plants and nurseries require significant irrigation and fertilizer that leads to high nutrient leaching. In southern California, a large producer of Avocados and nursery plant, waterways are often subjected to elevated nutrient concentrations, which stress the aquatic ecosystem. In this research, the specific objectives are to determine optimal irrigation and fertilizer application rates for minimizing nutrient and sediment export from avocado groves and nurseries. Altered irrigation and fertilizer application experiments will be implemented and monitored at the San Diego State University's Santa Margarita Ecological Reserve, which contains a 12 ha avocado grove and newly constructed 0.4 ha nursery. The study will last for twelve months, with runoff from natural rainfall or irrigation sampled and analyzed for nutrient concentrations on a monthly basis. The growth rate, leaf nutrient content and plant yield will also be monitored monthly. The nursery site is divided into eight plots (13.5-m x 13.5-m), with each plot containing 1200 plants consisting of four commonly used landscaping varieties in southern California. The avocado grove of the Hass variety is divided into four 1-ha plots. The experimental plots represent combinations of irrigation and fertilization practices with different methods and rates. In all cases, irrigation is fully automated based on soil moisture. To assess the effectiveness of the altered irrigation and fertilizer strategies, runoff water quality and plant yield will be compared to controlled treatments. This research is intended to provide a better understanding of how irrigation and fertilizer management can be used for the long-term reduction of nutrients in the Santa Margarita Watershed, which in turn will lead to improved

Full Text Available Knowledge of genetic and adaptive traits of reproductive materials used in the nursery system of wild cherry, could be an useful instrument to improve ecological and economic sustainability of plantation ecosystems. This work reports results from a research which the objectives were: 1 to study the genetic variation of a Prunus avium L. Population, used for seed harvesting, through its multi-locus genotypes detected by starch gel electrophoresis; 2 to analyze the level of genetic variation within and among different steps in a commercial nursery system (basic population and sub-populations, seedlings aged S1T1 and S1T2, plantation. Results showed low genetic variation levels of the basic population, similar to a reference system of other 12 wild cherry Italian populations and to other French and Caucasian materials. The genetic distances among Monte Baldo and some closer Lombardy provenances (Area Garda, Bosco Fontana, Valtellina were smaller than the Venice Region populations (Monti Lessini and Asiago. Number of alleles and percentage of polymorphic loci within the complex of Monte Baldo provenance and multiplication materials were similar, whilst a variable value of Fis was noted. Indeed, along with the nursery system until the plantation, heterozygosis initially (S1T1 increased, then decreased proceeding to the plantation. This fluctuation of FIS values could be determined by seed lots characterized initially by higher levels of variation, due to self-incompatibility. In the following steps, a possible selection pressure can affect randomly the genotypic structure of wild cherry by increasing the homozygosity. There is not among population a well defined geographic characterization, as suggested by genetic distances, therefore homogeneous seed harvest could be established an area larger than geographic and administrative borders. On this way we could have reproductive material with a wide genetic base and environmental adaptability. To

The influence of a water deficit treatment and mycorrhizal inoculation with Pisolithus tinctorius (Pers.) Coker and Couch on the water relations, gas exchange, and plant growth in Arbutus unedo L. plants was studied in order to evaluate the hardening process during the nursery period. The ability to withstand the adverse conditions after transplantation was also studied. Mycorrhizal and non-mycorrhizal seedlings of A. unedo were pot-grown for 4 months in a greenhouse (nursery period), during which time two irrigation treatments, well watered (100% water holding capacity, leaching 20% of the applied water) and deficit irrigation (50% of the well watered), were applied. Subsequently, the plants were transplanted to the field and well irrigated (transplanting period), after which and until the end of the experiment they received no water (establishment period). At the end of the nursery period, both water deficit and mycorrhizae were seen to have altered the plant morphology. Mycorrhizal plants had lower leaf area and improved leaf color parameters, while the water deficit increased root dry weight and the root/shoot ratio. Mycorrhizal plants had higher leaf water potential values than non-inoculated plants. Mycorrhizae increased stomatal conductance and photosynthesis values, especially in stressed plants. Drought led to an osmotic adjustment and a decrease in the leaf water potential values at turgor loss point in the mycorrhizal plants. Cell wall rigidity, measured as increased bulk modulus of elasticity, was decreased by the mycorrhizae effect. After transplanting, no differences were found in the water relations or gas exchange values between treatments. During the establishment period, the plants that had been exposed to both drought and mycorrhizae showed a better water status (higher leaf water and turgor potential values) and higher gas exchange values. In conclusion, water deficit and mycorrhizal inoculation of A. unedo plants in nursery produced changes in

Plant propagation is critical to augment the resource and has been the main concern for farmers and planters through history. India has evolved the science of Vṛkṣāyurveda to address the above issue. An effort is made here to review Vṛkṣāyurveda literature related to nursery techniques. Different libraries were visited and relevant review material obtained by hand search and from databases. Interaction with Sanskrit scholars and eminent scientists working in the field of Vṛkṣāyurveda, as well as the efforts of the authors of this paper, helped in the selection of pertinent literature. In the absence of original texts, authentic translations of the publications were referred. A conscious decision was made to limit the search to the fields of seed storage, pretreatment and nutrition of seedlings. To have a comparative account recent trends and literature on nursery technology were also examined. This was supplemented by interviews with traditional organic farmers. Our survey revealed that the time period of the literature pertaining to Vṛkṣāyurveda ranges from BCE 1200 to the present times. The subject has evolved from morphological descriptions and uses of plants, in texts such as Ṛgveda and Atharvaveda, to treatises dedicated solely to the art of growing plants like Kṛṣi-Parāśara and Vṛkṣāyurveda. It is also evident that there were important periods when more works appeared across subjects such as water divining, soil types, seed collection and storage, propagation, germination and sprouting, watering regimen, pest, and disease control. The review revealed that valuable information pertaining to nursery techniques is available in Vṛkṣāyurveda, which can be used in the development of nursery protocol. This will not only help in effective organic nursery management, but also ensure the health and livelihood security of the communities involved and effective waste management.

Perceptions of nursery staff and parent views of healthy eating promotion in preschool settings: an exploratory qualitative study

2016-08-01

Full Text Available Abstract Background In the UK just over a fifth of all children start school overweight or obese and overweight 2–5 year olds are at least 4 times more likely to become overweight adults. This can lead to serious future health problems. The WHO have recently highlighted the preschool years as a critical time for obesity prevention, and have recommended preschools as an ideal setting for intervention. However, existing evidence suggests that the preschool environment, including the knowledge, beliefs and practices of preschool staff and parents of young children attending nurseries can be a barrier to the successful implementation of healthy eating interventions in this setting. Methods This study examined the perceptions of preschool centre staff and parents’ of preschool children of healthy eating promotion within preschool settings. The participants were preschool staff working in private and local authority preschool centres in the North East of England, and parents of preschool children aged 3–4 years. Preschool staff participated in semi-structured interviews (n = 16 female, 1 male. Parents completed a mapping activity interview (n = 14 mothers, 1 father. Thematic analysis was applied to interpret the findings. Results Complex communication issues surrounding preschool centre dietary ‘rules’ were apparent. The staff were keen to promote healthy eating to families and felt that parents needed ‘education’ and ‘help’. The staff emphasised that school policies prohibited providing children with sugary or fatty snacks such as crisps, cakes, sweets and ‘fizzy’ drinks, however, some preschool centres appeared to have difficulty enforcing such guidelines. Parents were open to the idea of healthy eating promotion in preschool settings but were wary of being ‘told what to do’ and being thought of as ‘bad parents’. Conclusions There is a need to further explore nursery staff members’ personal perceptions of

The bays and estuaries of the southeast United States coast generally are thought to serve as nursery areas for various species of coastal sharks, where juvenile sharks find abundant food and are less exposed to predation by larger sharks. Because these areas typically support substantial commercial and recreational fisheries, fishing mortality of sharks in the nurseries particularly by bycatch, may be significant. This two-year project assessed the relative importance of two estuaries of the...

Baboons (Papio hamadryas anubis) of a conventional breeding colony were nursery-reared to create a specific pathogen-free (SPF) baboon-breeding program. Because the founding generations were nursery-reared until 2 years of age, it was suspected that the SPF baboons would exhibit increased reproductive challenges as adults. Mothering behavior was of interest, because SPF females were not exposed to parental role models during the nursery-rearing process. We compared reproductive data from the SPF baboon breeding program during its first 10 years with data from age-matched baboons during the same period from an established, genetically-similar conventional breeding colony. We also evaluated records documenting mother-infant behaviors within the SPF colony. The average age of menarche in SPF females was 3.3 years. The overall live birth rate of both SPF and conventional females was approximately 90%, with no difference in pregnancy outcome between the two colonies. The average age at first conception for SPF females was earlier (4.2 years) than that of the conventional females (4.7 years). In both colonies, primiparous females were more likely to abort than multiparous females. Similarly, primiparous females were more likely to lose their infants to death or human intervention. A mothering score system was developed in the SPF colony to facilitate intervention of poor mother-infant relationships. Records revealed 70% of SPF mothers were able to raise one or more of their infants successfully to at least 180 days of age, which did not differ from conventional mothers. SPF females returned to post-partum amenorrhea 27 days sooner on average than the conventional females, independent of dam age. The nursery-rearing process used for recruitment into the SPF colony therefore did not have an adverse effect on reproduction or rearing offspring. © 2013 Wiley Periodicals, Inc.

The role of the neonatal nurse practitioner in the community hospital level I nursery.

Hatch, Julie

2012-01-01

Neonatal nurse practitioners (NNPs) have played a significant role in providing medical coverage to many of the country's Level III neonatal intensive care units (NICUs). Extensive education and experience are required for a nurse practitioner (NP) to become competent in caring for these critically ill newborns. The NNP can take this competence and experience and expand her role out into the community Level I nurseries. Clinical care of the infants and close communication with parents, pediatricians, and the area tertiary center provide a community service with the goal of keeping parents and babies together in the community hospital without compromising the health of the baby. The NNP service, with 24-hour nursery and delivery coverage, supports an ongoing obstetric service to the community hospital. The NNP's experience enables her to provide a neonatal service that encompasses a multitude of advanced practice nursing roles.

Full Text Available In present life conditions, especially in urban environment, children have very poor conditions for physical activities, or for movement in general. According to the new researches, working conditions and quality of work in nurseries and schools, especially if they are related to physical exercises, have certain influences on overall development of pre-school and school children. Childhood is ideal time for correction of numerous postural disturbances and deformities, whether they are congenital or acquired by injury, wrong body posture, or by poor nutrition. Playing is a power fultool for directing correct development of children, so very of ten it has to be adapted to age, capabilities, interests and needs of children.

2010-01-01

Mosaic, or patchy, stunting of bareroot conifer seedlings is thought to be caused by deficiencies of mycorrhizal fungi following fumigation, resulting in reduced nutrient uptake, particularly phosphorus. Mosaic stunting of jack pine (Pinus banksiana) seedlings was observed in 2005 at the USDA Forest Service JW Toumey Nursery in Watersmeet, MI. We initiated a study to...

The seascape of demersal fish nursery areas in the North Mediterranean Sea, a first step towards the implementation of spatial planning for trawl fisheries.

Full Text Available The identification of nursery grounds and other essential fish habitats of exploited stocks is a key requirement for the development of spatial conservation planning aimed at reducing the adverse impact of fishing on the exploited populations and ecosystems. The reduction in juvenile mortality is particularly relevant in the Mediterranean and is considered as one of the main prerequisites for the future sustainability of trawl fisheries. The distribution of nursery areas of 11 important commercial species of demersal fish and shellfish was analysed in the European Union Mediterranean waters using time series of bottom trawl survey data with the aim of identifying the most persistent recruitment areas. A high interspecific spatial overlap between nursery areas was mainly found along the shelf break of many different sectors of the Northern Mediterranean indicating a high potential for the implementation of conservation measures. Overlap of the nursery grounds with existing spatial fisheries management measures and trawl fisheries restricted areas was also investigated. Spatial analyses revealed considerable variation depending on species and associated habitat/depth preferences with increased protection seen in coastal nurseries and minimal protection seen for deeper nurseries (e.g. Parapenaeus longirostris 6%. This is partly attributed to existing environmental policy instruments (e.g. Habitats Directive and Mediterranean Regulation EC 1967/2006 aiming at minimising impacts on coastal priority habitats such as seagrass, coralligenous and maerl beds. The new knowledge on the distribution and persistence of demersal nurseries provided in this study can support the application of spatial conservation measures, such as the designation of no-take Marine Protected Areas in EU Mediterranean waters and their inclusion in a conservation network.

Khalifian, S; Golden, W C; Cohen, B A

2017-06-01

Skin provides several important homeostatic functions to the developing neonate. However, no consensus guidelines exist in the United States for skin care in the healthy term newborn. We performed a study of skin and umbilical cord care (including bathing practices, vernix removal and antiseptic cord application) in newborn nurseries and mother-baby units throughout the state of Maryland to determine practices in a variety of clinical settings and assess if uniformity in skin care exists. These data were then assessed in the context of a review of the current literature. We received responses from over 90% of nurseries across the state. In our cohort, practices varied widely between institutions and specific populations, and often were not evidence-based or were contrary to best practices discussed in the scientific literature. The frequent departures from evidence that occur regarding the aforementioned practices are likely due to a lack of consensus on these issues as well as limited data on such practices, further highlighting the need for data-driven guidelines on newborn skin care.

Species richness and abundance of epibenthic fishes were quantified with daytime beam trawl tows in shallow water habitats during April-November 2000 of three mid-coast Maine estuaries: Casco Bay, Muscongus Bay and the Weskeag River. Five shallow (Gasterosteus aculeatus, Apeltes quadracus, Pungitius pungitius, Myoxocephalus aenaeus, and Cylcopterus lumpus. The fish community of mid-coast estuaries was dominated by young-of-the-year (YOY) and juvenile fishes and all of the habitat types function as nursery areas. Twelve species (38%) of commercial and recreational importance were collected in the three estuaries, but the percentage was higher in Casco Bay (44%) and the Weskeag River (46%). These species included Anguilla rostrata, Clupea harengus, Gadus morhua, Microgadus tomcod, Pollachius virens, Urophycis chuss, Urophycis regia, Urophycis tenuis, Osmerus mordax, Macrozoarces americanus, Tautogolabrus adspersus, and Pleuronectes americanus. Four species, G. morhua, M. tomcod, P. virens, and U. tenuis were more common in spring than summer or autumn. P. americanus was most abundant in summer followed by spring and autumn. This study documents the importance of shallow estuarine areas in Maine as nurseries for these species.

Stenstroem, Elna [Swedish Univ. of Agricultural Sciences, Uppsala (Sweden). Dept. of Forest Mycology and Pathology; Arvidsson, Bernt [Svenska Skogsplantor AB, Joenkoeping (Sweden)

2001-07-01

During the 1990s, there were serious outbreaks of the pathogen Lophodermium seditiosum on pine seedlings in Swedish forest nurseries, even though the seedlings had been treated with the fungicide propiconazole. The present experiment was carried out to evaluate two other fungicides, fluazinam and azoxystrobin, as possible alternatives to propiconazole. In the tests, which were all carried out in the same forest nursery, seedlings were treated with either propiconazole, fluazinam. or azoxystrobin, and the proportion of needles with ascocarps of L. seditiosum and the number of ascocarps per needle were recorded over the following 2 yrs. Seedlings treated with azoxystrobin already appeared healthier than control seedlings in September of the first year, and by November all azoxystrobin-treated seedlings had fewer ascocarps per needle compared with control seedlings. In autumn of the second year, there were no ascocarps on seedlings treated with fluazinam or azoxystrobin, whereas seedlings treated with propiconazole had similar numbers of ascocarps to non-treated control seedlings.

The incubator environment is essential for optimal physiological functioning and development of the premature infant but the infant is ultimately required to make a successful transfer from incubator to open cot in order to be discharged from hospital. Criteria for transfer lack a systematic approach because no clear, specific guideline predominates in clinical practice. Practice variation exists between continents, regions and nurseries in the same countries, but there is no recent review of current practices utilised for transferring premature infants from incubators to open cots. To document current practice for transferring premature infants to open cots in neonatal nurseries. A descriptive, cross-sectional survey. Twenty-two neonatal intensive care units and fifty-six high dependency special care baby units located in public hospitals in Australia and New Zealand. A sample of 78 key clinical nursing leaders (nurse unit managers, clinical nurse consultants or clinical nurse specialists) within neonatal nurseries identified through email or telephone contact. Data were collected using a web-based survey on practice, decision-making and strategies utilised for transferring premature infants from incubators to open cots. Descriptive statistics (frequencies and crosstabs) were used to analyse data. Comparisons between groups were tested for statistical significance using Chi-squared or Fisher's exact test. Significant practice variation between countries was found for only one variable, nursing infants clothed (p=0.011). Processes and practices undertaken similarly in both countries include use of incubator air control mode, current weight criterion, thermal challenging, single-walled incubators and heated mattress systems. Practice variation was significant between neonatal intensive care units and special care baby units for weight range (p=0.005), evidence-based practice (p=0.004), historical nursery practice (p=0.029) and incubator air control mode (p=0

Hinrichsen, H.-H.; von Dewitz, B.; Lehmann, A.; Bergström, U.; Hüssy, K.

2017-06-01

In this study the drift of eastern Baltic cod larvae and juveniles spawned within the historical eastern Baltic cod spawning grounds was investigated by detailed drift model simulations for the years 1971-2010, to examine the spatio-temporal dynamics of environmental suitability in the nursery areas of juvenile cod settlement. The results of the long-term model scenario runs, where juvenile cod were treated as simulated passively drifting particles, enabled us to find strong indications for long-term variations of settlement and potentially the reproduction success of the historically important eastern Baltic cod nursery grounds. Only low proportions of juveniles hatched in the Arkona Basin and in the Gotland Basin were able to settle in their respective spawning ground. Ocean currents were either unfavorable for the juveniles to reach suitable habitats or transported the juveniles to nursery grounds of neighboring subdivisions. Juveniles which hatched in the Bornholm Basin were most widely dispersed and showed the highest settlement probability, while the second highest settlement probability and horizontal dispersal was observed for juveniles originating from the Gdansk Deep. In a long-term perspective, wind-driven transport of larvae/juveniles positively affected the settlement success predominately in the Bornholm Basin and in the Bay of Gdansk. The Bornholm Basin has the potential to contribute on average 54% and the Bay of Gdansk 11% to the production of juveniles in the Baltic Sea. Furthermore, transport of juveniles surviving to the age of settlement with origin in the Bornholm Basin contributed on average 13 and 11% to the total settlement in the Arkona Basin and in the Gdansk Deep, respectively. The time-series of the simulated occupied juvenile cod habitat in the Bornholm Basin and in the Gdansk Deep showed a similar declining trend as the Fulton's K condition factor of demersal 1-group cod, which may confirm the importance of oxygen-dependent habitat

Persistence and co-occurrence of demersal nurseries in the Strait of Sicily (central Mediterranean): Implications for fishery management

Science.gov (United States)

Garofalo, G.; Fortibuoni, T.; Gristina, M.; Sinopoli, M.; Fiorentino, F.

2011-08-01

This study investigated the nurseries of seven commercially important demersal species of the northern sector of the Strait of Sicily (central Mediterranean): red mullet, European hake, horned octopus, deep-water rose shrimp, greater forkbeard, Norway lobster and giant red shrimp. An eleven-year series of data collected through experimental trawling in the Strait of Sicily during spring and autumn was analyzed. The spatio-temporal persistence of the high-density aggregations (hot spots) of juvenile individuals in their first year of life was investigated to identify habitats that serve as nurseries. The density of recruits within the persistent nurseries was used as a proxy of the unit area contribution of individuals which recruit to the adult population. The spatial distribution patterns of the recruits of most the species were well defined and very stable in the long term. Persistent and potentially highly productive nurseries of European hake, deep-water rose shrimp and greater forkbeard were identified off the southern coast of Sicily. Persistent areas of recruits concentration were also observed for the other species investigated, but their specific potential contribution of individuals to the adult population was not substantial compared to adjacent grounds. The close or overlapped localization of sites which regularly host vulnerable life stages of different exploited species, revealed an area of great ecological significance which probably plays a major role in the dynamics of the fishery resources in the Strait of Sicily. Appropriate spatial protection measures of this area, including marine protected area designation, could complement conventional management approach for ensuring the long-term sustainability of these fisheries and stocks conservation.

Immigration and early life stages recruitment of the European flounder (Platichthys flesus) to an estuarine nursery: The influence of environmental factors

Science.gov (United States)

Amorim, Eva; Ramos, Sandra; Elliott, Michael; Bordalo, Adriano A.

2016-01-01

Connectivity between coastal spawning grounds and estuarine nurseries is a critical step in the life cycle of many fish species. Larval immigration and transport-associated physical-biological processes are determinants of recruitment success to nursery areas. The recruitment of the European flounder, Platichthys flesus, to estuarine nurseries located at the southern edge of the species distribution range, has been usually investigated during its juvenile stages, while estuarine recruitment during the earlier planktonic life stage remains largely unstudied. The present study investigated the patterns of flounder larval recruitment and the influence of environmental factors on the immigration of the early life stages to the Lima estuary (NW Portugal), integrating data on fish larvae and post-settlement individuals (< 50 mm length), collected over 7 years. Late-stage larvae arrived at the estuary between February and July and peak abundances were observed in April. Post-settlement individuals (< 50 mm) occurred later between April and October, whereas newly-settled ones (< 20 mm) were found only in May and June. Variables associated with the spawning, survival and growth of larvae in the ocean (sea surface temperature, chlorophyll a and inland hydrological variables) were the major drivers of flounder occurrence in the estuarine nursery. Although the adjacent coastal area is characterized by a current system with strong seasonality and mesoscale variability, we did not identify any influence of variables related with physical processes (currents and upwelling) on the occurrence of early life stages in the estuary. A wider knowledge on the influence of the coastal circulation variability and its associated effects upon ocean-estuarine connectivity is required to improve our understanding of the population dynamics of marine spawning fish that use estuarine nurseries.

Impact of ectohumus application in birch and pine nurseries on the presence of soil mites (Acari, Oribatida in particular

2016-03-01

Full Text Available Intensively used forest nurseries are characterised by degradation processes that lead to a drop in the quality of seedlings. The main reason of this problem is a decrease in biological soil diversity. Therefore, an attempt of nursery soil enrichment by introducing ectohumus – as compost and fresh litter – from the pine forest was carried out. The research was carried out in 2009–2011 in the Bielawy forest nursery near the city of Toruń, Poland. The objective of the study was to determine the impact of organic fertilisation (compost made up of forest humus and mulching using fresh ectohumus on the density and community composition of Acari mites and on species composition of oribatid mites (Oribatida in the nurseries of silver birch and Scots pine. Mites, especially oribatid mites, were treated as bioindicators of soil biological activity. Research has shown that mulching using fresh ectohumus caused a multiple increase in the density of mites, especially in saprophagous mites Oribatida. Oribatid mites were clearly more numerous in birch cultivation than in that of pine. Overall, 27 species of oribatid mites were found. Mulching resulted in a significant growth in species diversity in both cultivations. The most numerous oribatid mite in the area under the study was Oribatula tibialis. This species was present in all plots and showed clear preference for birch cultivation. Tectocepheus velatus and Oppiella nova, common and known to be present in a variety of environments, were slightly less numerous.

Full Text Available Many games have been preserved as a custom, particularly among children, much after the young used to play them. In most of the cases, traditional games represent imitation of the adults’ society. Those games are numerous, with an easy start and ending, so the children use them in any possible situation. The implementation of these games and some traditional toys in the nurseries and primary schools in Novi Pazar, has proved our assumptions that teachers has given them positive marks, and even more important is that children are eager to use them and show some interests for their existence. A school can apply various sources within educational process and other out school activities.

Relevance of Vṛkṣāyurveda and other traditional methods for organic production of nursery seedlings of useful plants

Directory of Open Access Journals (Sweden)

Geetha Suresh

2013-01-01

Full Text Available Plant propagation is critical to augment the resource and has been the main concern for farmers and planters through history. India has evolved the science of Vṛkṣāyurveda to address the above issue. An effort is made here to review Vṛkṣāyurveda literature related to nursery techniques. Different libraries were visited and relevant review material obtained by hand search and from databases. Interaction with Sanskrit scholars and eminent scientists working in the field of Vṛkṣāyurveda, as well as the efforts of the authors of this paper, helped in the selection of pertinent literature. In the absence of original texts, authentic translations of the publications were referred. A conscious decision was made to limit the search to the fields of seed storage, pretreatment and nutrition of seedlings. To have a comparative account recent trends and literature on nursery technology were also examined. This was supplemented by interviews with traditional organic farmers. Our survey revealed that the time period of the literature pertaining to Vṛkṣāyurveda ranges from BCE 1200 to the present times. The subject has evolved from morphological descriptions and uses of plants, in texts such as R.gveda and Atharvaveda, to treatises dedicated solely to the art of growing plants like Kṛṣi-Parāśara and Vṛkṣāyurveda. It is also evident that there were important periods when more works appeared across subjects such as water divining, soil types, seed collection and storage, propagation, germination and sprouting, watering regimen, pest, and disease control. The review revealed that valuable information pertaining to nursery techniques is available in Vṛkṣāyurveda, which can be used in the development of nursery protocol. This will not only help in effective organic nursery management, but also ensure the health and livelihood security of the communities involved and effective waste management.

2017-09-01

Full Text Available The aim of the study was to assess the effects of organic fertilization on selected chemical properties of the soil and the activity of dehydrogenase and β-glucosidase in the soil of forest nursery. The main goal was to evaluate the role of organic fertilizers in carbon storage in the forest nursery soil. Sample plots were located in northern Poland in the Polanów Forest District on a forest nursery. Soil samples were collected from horizon 0–20 cm for laboratory analyzes. In soil samples pH, soil texture, and organic carbon, nitrogen, base cation contents, dehydrogenase activity and β-glucosidase activity were determined. The obtained results were used to evaluate the carbon storage. The results confirm the beneficial effect of the applied organic fertilizer on chemical properties of the soils under study and their biological activity. The applied organic fertilizers had an impact on increased accumulation of soil organic matter. In the soils investigated, there was an increase in the activity of such enzymes as dehydrogenases and β-glucosidase.

Meningococcal infection is fatal in 10% of cases, and age-specific attack rates are highest in infancy. A nursery outbreak was declared just before a bank holiday weekend in August 2010, when two children attending the same nursery were confirmed to have meningococcal infection. Although such outbreaks are rare, they generate considerable public alarm and are challenging to manage and control. This report describes the investigation and public health response to the outbreak. Both cases had relatively mild disease and were confirmed as having serogroup B infection. Chemoprophylaxis and advice were given to most of the 146 children and 30 staff at the nursery. Within 28 hours of declaring the outbreak, over 95% of parents received information, advice and prescriptions for their children. GPs were also given information and the after-hours service provided continuity over the weekend. No further cases were identified and the outbreak was closed four weeks after being declared. Considerable logistical challenges were involved in providing timely advice and chemoprophylaxis to the entire nursery and staff one day before a bank holiday weekend. The speed of the public health response and implementation of preventive measures was crucial in providing assurance to parents and staff, and reducing their anxiety. The decision to provide on-site prescribing at the nursery (coupled with information sessions and individual counselling) proved to be a key implementation-success factor. Effective coordination and management by the outbreak control team was able to rapidly provide leadership, delegate tasks, identify gaps, allocate resources and ensure a proactive media response. A number of useful lessons were learnt and recommendations were made for future local practice.

Full Text Available The knowledge of the growth in tree nursery of perennial plant species is important in order to develop good agronomical practices for the selection of the plants that will be taken to the fields. This information is required for the hybrids OxG of oil palms under the conditions of the palm growing Colombian region. In two soils with different moisture retention and air space, the growth and development in nursery of hybrid oil palms OxG F1 (Elaeis oleifera x Elaeis guineensis and Tenera DxP (Elaeis guineensis x Elaeis guineensis were evaluated. Plants of OxG material were larger and accumulated more biomass in most of its constituent bodies in comparison with plants of DxP material. Likewise, both plants were quite different in the order of preference distribution and accumulation of assimilated species at the petiole basis, stem and petiole. In comparison with DxP, the OxG material showed the differential characteristic to allocate more of their assimilated species growth the plant root system. Moreover, it was determined that OxG plants exhibit better growth and development compared with DxP plants in nursery stage with high moisture retention and low aeration soils. Additionally, we identified and selected three morphological features with discriminatory authority to differentiate the growth behavior of the two types of oil palms regarding the soil used in the nursery: section area of the petiole (PxS, rachis length (RL and leaf emission (LE.

A study was made in diets offered to a group of pre-school children, whose mean age was 67 months and remained the whole day in three day care centers from Juiz de Fora, M.G., Brazil. For sampling, the duplicate portion technique was used, and the diets were collected and analyzed separately each day in the 3 nurseries. Instrumental neutron activation analysis was applied to the determination of 16 elements. The daily dietary intake values were compared to the RDA (children 4-6 years old). Based on this reference, Ca, Fe, Se and Zn were found to be deficient, Mg and Mn were comparable to the RDA and the Cl and Na concentrations were higher compared to their RDA. For the other elements measured, there are no RDA's for children. (author)

Use of the heat dissipation method for sap flow measurement in citrus nursery trees1

Full Text Available Sap flow could be used as physiological parameter to assist irrigation of screen house citrus nursery trees by continuous water consumption estimation. Herein we report a first set of results indicating the potential use of the heat dissipation method for sap flow measurement in containerized citrus nursery trees. 'Valencia' sweet orange [Citrus sinensis (L. Osbeck] budded on 'Rangpur' lime (Citrus limonia Osbeck was evaluated for 30 days during summer. Heat dissipation probes and thermocouple sensors were constructed with low-cost and easily available materials in order to improve accessibility of the method. Sap flow showed high correlation to air temperature inside the screen house. However, errors due to natural thermal gradient and plant tissue injuries affected measurement precision. Transpiration estimated by sap flow measurement was four times higher than gravimetric measurement. Improved micro-probes, adequate method calibration, and non-toxic insulating materials should be further investigated.

Full Text Available In the circumstances of only a limited number of pesticides being approved for use in forest nurseries, it is necessary to also examine the efficacy of new products available on the European market that stimulate growth and improve resilience and vitality among seedlings and saplings, with a view to the application of these products forming part of an integrated programme of plant protection. This paper describes trials of the three commercially available fertilizer products Actifos, Zielony Busz and Effective Microorganisms (EM, as carried out in seven Polish nurseries in an attempt to promote the growth of shoots and root systems of seedlings and saplings. In 64% of cases of it being used, Actifos was shown to stimulate growth significantly beyond control levels in the shoots of oak, beech, pine, spruce and alder saplings as well as the roots of young alders and oaks.

Environmental impact of passive house nursery

Energy Technology Data Exchange (ETDEWEB)

Vares, S., Email: sirje.vares@vtt.fi

2012-06-15

It is often believed that reduction in energy use automatically leads to the total reduction of the carbon footprint and other emissions. To achieve better energy efficiency more raw materials may be needed not only for insulation and better windows but also for heating systems like ground source heat and solar panels. The use of advanced building systems increase the use of electricity and in winter where electricity production is already inadequate the additional stand-by power plants must be taken in use. These are not as effective as CHP plants for heat production. Moreover also the passive house structures can be produced in dozens ways and from many different materials which all have different service life, different need for maintenance and also different effect on the overall carbon footprint. Finally as the nursery is the overall concept, besides the building structures outdoor playgrounds and specific operations requiring day care trips, personnel commuting and waste treatment must be taken into account.

ABSTRACT This study describes the results of a randomized clinical trial investigating the effect of oxytetracycline treatment dose and mode of administration on the selection of antibiotic-resistant coliform bacteria in fecal samples from nursery pigs. Nursery pigs (pigs of 4 to 7 weeks of age) in five pig herds were treated with oxytetracycline for Lawsonia intracellularis-induced diarrhea. Each group was randomly allocated to one of five treatment groups: oral flock treatment with a (i) high (20 mg/kg of body weight), (ii) medium (10 mg/kg), or (iii) low (5 mg/kg) dose, (iv) oral pen-wise (small-group) treatment (10 mg/kg), and (v) individual intramuscular injection treatment (10 mg/kg). All groups were treated once a day for 5 days. In all groups, treatment caused a rise in the numbers and proportions of tetracycline-resistant coliform bacteria right after treatment, followed by a significant drop by the time that the pigs left the nursery unit. The counts and proportions of tetracycline-resistant coliforms did not vary significantly between treatment groups, except immediately after treatment, when the highest treatment dose resulted in the highest number of resistant coliforms. A control group treated with tiamulin did not show significant changes in the numbers or proportions of tetracycline-resistant coliforms. Selection for tetracycline-resistant coliforms was significantly correlated to selection for ampicillin- and sulfonamide-resistant strains but not to selection for cefotaxime-resistant strains. In conclusion, the difference in the dose of oxytetracycline and the way in which the drug was applied did not cause significantly different levels of selection of tetracycline-resistant coliform bacteria under the conditions tested. IMPORTANCE Antimicrobial resistance is a global threat to human health. Treatment of livestock with antimicrobials has a direct impact on this problem, and there is a need to improve the ways that we use antimicrobials in

“Little Cogs of the Huge State Machine”. Formation and Development of Nursery Care System in 1920-1930s (on the Materials of the Republic of Germans in the Volga Region

Directory of Open Access Journals (Sweden)

Lyudmila A. Falaleeva

2017-06-01

Full Text Available The article is devoted to insufficiently studied aspects of the history of the Volga Germans. On the basis of the documents kept in the State Historical Archives of the Volga Germans, the author reveals the peculiarities of formation and development of the nursery care system in the USSR of Volga Germans in 1920-1930s. In the article measures on preparing medical and pedagogical staff are reviewed. It was concluded that the establishment of nurseries led not only to improvement of children’s health, but also released labour force of peasant women for the national economy. The author found that the first information about the opening of nurseries in the German autonomy is related to 1921 – from that moment an active process of formation of the Soviet system of nursery facilities in the region had begun. Due to large-scale famine of the early 1920s, existence of nurseries was under threat, despite the active government policy on this issue. Only in 1925 the matter of protection of motherhood and childhood stabilized, and with active support of female population of Volga Germans started to rapidly gain the momentum. In the mid-1930s more than 5 000 children in ASSR NP became pupils of nurseries. All the year round a woman was able to break free from the hassle of taking care of children and the young generation from the first years of life was brought up under state control. The operation of nurseries caused both a need and an interest among German women, in contrast to many other social projects of the Soviet power against women. The author concludes that the mass distribution of nurseries in the territory of ASSR NP and their introduction into the social environment, allows considering them as significant administrative practices aimed at the destruction of traditional ways of life of women, effective even in the national autonomy.

Spawning and nursery habitats of neotropical fish species in the tributaries of a regulated river

This chapter provides information on ontogenetic patterns of neotropical fish species distribution in tributaries (Verde, Pardo, Anhanduí, and Aguapeí rivers) of the Porto Primavera Reservoir, in the heavily dammed Paraná River, Brazil, identifying key spawning and nursery habitats. Samplings were conducted monthly in the main channel of rivers and in marginal lagoons from October through March during three consecutive spawning seasons in 2007-2010. Most species spawn in December especially in Verde River. Main river channels are spawning habitats and marginal lagoons are nursery areas for most fish, mainly for migratory species. The tributaries have high diversity of larvae species: a total of 56 taxa representing 21 families, dominated by Characidae. Sedentary species without parental care are more abundant (45.7%), and many long-distance migratory fish species are present (17.4%). Migrators included Prochilodus lineatus, Rhaphiodon vulpinus, Hemisorubim platyrhynchos, Pimelodus maculatus, Pseudoplatystoma corruscans, Sorubim lima, two threatened migratory species: Salminus brasiliensis and Zungaro jahu, and one endangered migratory species: Brycon orbignyanus. Most of these migratory species are vital to commercial and recreational fishing, and their stocks have decreased drastically in the last decades, attributed to habitat alteration, especially impoundments. The fish ladder at Porto Primavera Dam appears to be playing an important role in re-establishing longitudinal connectivity among critical habitats, allowing ascent to migratory fish species, and thus access to upstream reaches and tributaries. Establishment of Permanent Conservation Units in tributaries can help preserve habitats identified as essential spawning and nursery areas, and can be key to the maintenance and conservation of the fish species in the Paraná River basin.

High temperatures result in smaller nurseries which lower reproduction of pollinators and parasites in a brood site pollination mutualism.

In a nursery pollination mutualism, we asked whether environmental factors affected reproduction of mutualistic pollinators, non-mutualistic parasites and seed production via seasonal changes in plant traits such as inflorescence size and within-tree reproductive phenology. We examined seasonal variation in reproduction in Ficus racemosa community members that utilise enclosed inflorescences called syconia as nurseries. Temperature, relative humidity and rainfall defined four seasons: winter; hot days, cold nights; summer and wet seasons. Syconium volumes were highest in winter and lowest in summer, and affected syconium contents positively across all seasons. Greater transpiration from the nurseries was possibly responsible for smaller syconia in summer. The 3-5°C increase in mean temperatures between the cooler seasons and summer reduced fig wasp reproduction and increased seed production nearly two-fold. Yet, seed and pollinator progeny production were never negatively related in any season confirming the mutualistic fig-pollinator association across seasons. Non-pollinator parasites affected seed production negatively in some seasons, but had a surprisingly positive relationship with pollinators in most seasons. While within-tree reproductive phenology did not vary across seasons, its effect on syconium inhabitants varied with season. In all seasons, within-tree reproductive asynchrony affected parasite reproduction negatively, whereas it had a positive effect on pollinator reproduction in winter and a negative effect in summer. Seasonally variable syconium volumes probably caused the differential effect of within-tree reproductive phenology on pollinator reproduction. Within-tree reproductive asynchrony itself was positively affected by intra-tree variation in syconium contents and volume, creating a unique feedback loop which varied across seasons. Therefore, nursery size affected fig wasp reproduction, seed production and within-tree reproductive phenology

Relationship Between Dietary Sugar Intake and Dental Caries Among Japanese Preschool Children with Relatively Low Sugar Intake (Japan Nursery School SHOKUIKU Study): A Nationwide Cross-Sectional Study.

Science.gov (United States)

Saido, Miyuki; Asakura, Keiko; Masayasu, Shizuko; Sasaki, Satoshi

2016-03-01

The WHO has recently proposed to halve the recommendation for free sugar intake from 10 to 5 % of energy intake to reduce the incidence of diseases such as obesity and dental caries. The Japanese population is suitable to confirm the appropriateness of this proposal, because dietary sugar intake in Japan is exceptionally low among developed countries. We sought to establish a method to estimate dietary sugar intake in Japan and to examine the relationship between sugar and the number of dental caries using data obtained from the Japan Nursery School SHOKUIKU study. Dietary intake during the preceding month and the number of caries was examined in children aged 5-6 years using a brief-type self-administered diet history questionnaire for Japanese preschool children completed by their guardians and another questionnaire on lifestyle. Multivariate Poisson regression models were used for the analysis. When subjects were ranked into quintiles by the proportion of energy from free sugar, those in higher quintiles had more caries than those in the lowest quintile. On close analysis, the number of caries among children with a relatively small proportion of energy intake from free sugar (3.18-3.77 %) was not significantly different from that in the lowest group (0.95-3.17 %). The recent proposition of WHO might be valid, because the adverse effect of relatively small proportion (approximately less than 5 %) of energy intake from free sugar on caries was not detected among the subjects in this study. However, more study will be necessary to reach a conclusion.

Fish utilisation of wetland nurseries with complex hydrological connectivity.

Directory of Open Access Journals (Sweden)

Ben Davis

Full Text Available The physical and faunal characteristics of coastal wetlands are driven by dynamics of hydrological connectivity to adjacent habitats. Wetlands on estuary floodplains are particularly dynamic, driven by a complex interplay of tidal marine connections and seasonal freshwater flooding, often with unknown consequences for fish using these habitats. To understand the patterns and subsequent processes driving fish assemblage structure in such wetlands, we examined the nature and diversity of temporal utilisation patterns at a species or genus level over three annual cycles in a tropical Australian estuarine wetland system. Four general patterns of utilisation were apparent based on CPUE and size-structure dynamics: (i classic nursery utlisation (use by recently settled recruits for their first year (ii interrupted peristence (iii delayed recruitment (iv facultative wetland residence. Despite the small self-recruiting 'facultative wetland resident' group, wetland occupancy seems largely driven by connectivity to the subtidal estuary channel. Variable connection regimes (i.e. frequency and timing of connections within and between different wetland units (e.g. individual pools, lagoons, swamps will therefore interact with the diversity of species recruitment schedules to generate variable wetland assemblages in time and space. In addition, the assemblage structure is heavily modified by freshwater flow, through simultaneously curtailing persistence of the 'interrupted persistence' group, establishing connectivity for freshwater spawned members of both the 'facultative wetland resident' and 'delayed recruitment group', and apparently mediating use of intermediate nursery habitats for marine-spawned members of the 'delayed recruitment' group. The diversity of utilisation pattern and the complexity of associated drivers means assemblage compositions, and therefore ecosystem functioning, is likely to vary among years depending on variations in hydrological

While practitioners are increasingly asked to be mindful of the evidence base of intervention programmes, evidence from rigorous trials for the effectiveness of interventions that promote oral language abilities in the early years is sparse. To evaluate the effectiveness of a language intervention programme for children identified as having poor oral language skills in preschool classes. A randomized controlled trial was carried out in 13 UK nursery schools. In each nursery, eight children (N = 104, mean age = 3 years 11 months) with the poorest performance on standardized language measures were selected to take part. All but one child were randomly allocated to either an intervention (N = 52) or a waiting control group (N = 51). The intervention group received a 15-week oral language programme in addition to their standard nursery curriculum. The programme was delivered by trained teaching assistants and aimed to foster vocabulary knowledge, narrative and listening skills. Initial results revealed significant differences between the intervention and control group on measures of taught vocabulary. No group differences were found on any standardized language measure; however, there were gains of moderate effect size in listening comprehension. The study suggests that an intervention, of moderate duration and intensity, for small groups of preschool children successfully builds vocabulary knowledge, but does not generalize to non-taught areas of language. The findings strike a note of caution about implementing language interventions of moderate duration in preschool settings. The findings also highlight the importance of including a control group in intervention studies. © 2016 Royal College of Speech and Language Therapists.

Reforestation is needed globally to help restore degraded sites, combat desertification, protect watersheds, and provide forest products. This involves planting forest tree seedlings grown in local nurseries, but technologies to produce quality seedlings are lacking in developing countries. Modern nursery containers used to propagate seedlings have internal-surface barriers (ribs or ridges) or side-slits to prevent root spiraling. These are cost prohibitive or unavailable in developing countries and so polybags (plastic bags) are more commonly used, despite their tendency to produce seedlings with deformed root systems that have less potential to establish on field sites. Discarded plastic bottles, which are readily available worldwide, may be a feasible alternative for seedling propagation. We conducted two experiments to assess the potential of repurposed plastic beverage bottles to grow quality trees: 1) Container Comparison–to evaluate Arizona walnut (Juglans major [Toor.] Heller) and Afghan pine (Pinus eldarica Medw.) seedling root and shoot development in two plastic bottle types compared to modern nursery containers and polybags, and 2) Bottle Modification–to examine the effects of root spiraling prevention techniques (side-slits, internal-ridges, and control) and container opacity (green, black, and clear) on Afghan pine seedling morphological attributes. Nursery growth and first-year seedling field performance were evaluated for both experiments. In experiment one, seedlings of both species had fewer spiraled roots in bottle containers compared to polybags. Arizona walnut had more fibrous root systems in polybags, while Afghan pine root system fibrosity was greatest in bottle containers. First-year field performance of both species was not affected by container type. In experiment two, less spiraled roots occurred in containers with air-slits and interior-ridges compared to the control. The effects of container opacity on seedling morphology were

Full Text Available This research had as objective to verify the influence in growth, nutrition and dry matter partition in oil palm seedling by type and dosages of slow release fertilizers (SRF and percentage of tray occupation by plastic containers during pre-nursery. The experiment consisted of 16 treatments, in factorial scheme: two types of SRF (Osmocote® e Basacote mini, two dosages (0 and 3 kg/m3 and four schemes for the container distribution used to attain 100%, 66%, 50% and 25% of tray occupation. An additional treatment composed of 15 x 15 cm plastic bags filled with soil was added. Pre-germinated seeds of oil palm were put in plastic containers of 120 cm3 containing substratum and in plastic bags containing soil. After three months, the seedlings were transplanted to 40 x 40 cm plastic bags containing soil. At this time, height, diameter, dry matter and concentration of N, P, K, Ca and Mg were evaluated. After 10 months, seedlings were evaluated for height and diameter and after 16 months, seedlings had the height, diameter and dry matter weight evaluated. Addition of SRF was fundamental for seedlings development. Different percentages of tray occupation by containers during pre-nursery did not influence height and diameter of oil palm seedlings at 10 and 16 months old. The evaluation after 10 months showed that plants fertilized with Osmocote® were higher than those fertilized with Basacote mini. The evaluations after 16 months showed that plants fertilized during the pre-nursery had higher height, diameter and leaflets, leaf, aboveground and total dry matter than plants not fertilized.

High temperatures result in smaller nurseries which lower reproduction of pollinators and parasites in a brood site pollination mutualism.

Directory of Open Access Journals (Sweden)

Anusha Krishnan

Full Text Available In a nursery pollination mutualism, we asked whether environmental factors affected reproduction of mutualistic pollinators, non-mutualistic parasites and seed production via seasonal changes in plant traits such as inflorescence size and within-tree reproductive phenology. We examined seasonal variation in reproduction in Ficus racemosa community members that utilise enclosed inflorescences called syconia as nurseries. Temperature, relative humidity and rainfall defined four seasons: winter; hot days, cold nights; summer and wet seasons. Syconium volumes were highest in winter and lowest in summer, and affected syconium contents positively across all seasons. Greater transpiration from the nurseries was possibly responsible for smaller syconia in summer. The 3-5°C increase in mean temperatures between the cooler seasons and summer reduced fig wasp reproduction and increased seed production nearly two-fold. Yet, seed and pollinator progeny production were never negatively related in any season confirming the mutualistic fig-pollinator association across seasons. Non-pollinator parasites affected seed production negatively in some seasons, but had a surprisingly positive relationship with pollinators in most seasons. While within-tree reproductive phenology did not vary across seasons, its effect on syconium inhabitants varied with season. In all seasons, within-tree reproductive asynchrony affected parasite reproduction negatively, whereas it had a positive effect on pollinator reproduction in winter and a negative effect in summer. Seasonally variable syconium volumes probably caused the differential effect of within-tree reproductive phenology on pollinator reproduction. Within-tree reproductive asynchrony itself was positively affected by intra-tree variation in syconium contents and volume, creating a unique feedback loop which varied across seasons. Therefore, nursery size affected fig wasp reproduction, seed production and within

Nursery inoculation with the arbuscular mycorrhizal fungus Glomus viscosum and its effect on the growth and physiology of hybrid artichoke seedlings

Directory of Open Access Journals (Sweden)

Angela Campanelli

2011-09-01

Full Text Available Most nurseries operating in Italy adopt high technologies and produce transplants that well suit and satisfy the grower’s need to produce high value crops. Mycorrhizas are discussed as a tool for improving and developing plant production in the nursery. Much research has been carried out on mycorrhizal symbiosis and we now know more about the symbiontic relationship between fungi and host plants. Plants receive numerous benefits from this symbiosis which are more macroscopic the earlier in the ontogenetic cycle this symbiosis is established. Therefore, it appears that the most effective period in which the inoculum should be made corresponds to the in-nursery growing stage. The earlier the plant is inoculated, the more evident the effect will be. In this study, several aspects related to the physiological foundations of arbuscular mycorrhiza in artichoke plants are presented. The main goal was to study the effects of mycorrhiza on the growth and physiological parameters of three hybrids of artichokes growing in the nursery. The experimental 3¥2 design included two treatments (with or without arbuscular mycorrhizal fungi and three hybrids of artichokes marketed by Nunhems (Opal F1, Madrigal F1, Concerto F1. Mycorrhizal plants have greater shoot length, leaf area, shoot and root fresh and dry mass, and root density. This also corresponded with increased photosynthetic rates and stomatal conductance of mycorrhizal plants. Mycorrhizal colonization improves relative water content and increases proline concentration in vegetal tissue. Inoculation produced the most beneficial effect on hybrid Madrigal F1 and on hybrid Opal F1; the best mycorrhizal affinity was enhanced when compared to hybrid Concerto F1. The results showed that mycorrhizal symbiosis stimulated the growth of inoculated seedlings providing a qualitatively good propagation material.

The relationship between habitat complexity and nursery provision for an estuarine-dependent fish species in a permanently open South African Estuary

Leslie, Timothy; James, Nicola C.; Potts, Warren M.; Rajkaran, Anusha

2017-11-01

Estuarine-dependent marine fish species rely on shallow, sheltered and food rich habitats for protection from predators, growth and ultimately recruitment to adult populations. Hence, habitats within estuaries function as critical nursery areas for an abundance of fish species. However, these habitats vary in the degree of nursery function they provide and few studies have quantitatively assessed the relative nursery value of different habitat types within estuaries, particularly in the context of habitat complexity. This study aimed to assess the nursery value of the dominant vegetated habitats, namely the submergent Zostera capensis (Setch.) (seagrass) beds and emergent Spartina maritima (Curtis) Fernald (salt marsh) beds in the Bushmans Estuary, South Africa. Biomass and stem density were sampled seasonally in order to gain insight into the vegetation dynamics of seagrass and salt marsh beds. Aerial cover, canopy height and underwater camera imagery were used to develop multiple complexity indices for prioritizing habitat complexity. The relatively consistent results of the dimensionless indices (interstitial space indices and fractal geometry) suggest that Z. capensis exhibits an overall greater degree of complexity than S. maritima, and hence it can be expected that fish abundance is likely to be higher in Z. capensis beds than in S. maritima habitats. Underwater video cameras were deployed in seagrass, salt marsh and sand flat habitats to assess the relative abundance and behaviour of the estuarine-dependent sparid Rhabosargus holubi (Steindachner 1881) in different habitats. The relative abundance of R. holubi was significantly higher in Z. capensis seagrass than S. maritima salt marsh and sand flats, whilst the behaviour of R. holubi indicated a high degree of habitat use in structured habitats (both Z. capensis and S. martima) and a low degree of habitat use in unstructured sand flat habitats.

2010-08-01

Full Text Available Jacaranda puberula, known as caroba, is a species that presents potential use for the recovery of degraded areas, since it possesses fast growth and adapts well to sandy and loamy soils. It presents great aggressiveness in secondary forests and it can be used as urban tree because it produces beautiful lilac flowers. With the intention of obtaining information about potential species for use in recovery of riparian forest, were tested in the nursery of the city hall of the municipal district of Colombo, the development of seedlings of Jacaranda puberula submitted at 30, 50 and 70% of shading. There were used 40 seedlings by treatment and there were evaluated the following parameters: height (60, 90 and 120 days and diameter (90 and 120 days of all seedlings, leaf area and root and shoot dry weight of 6 seedlings per treatment. The largest averages of the analyzed variables were obtained for the 30% shading, except for root dry weight.  The seedlings exposed to full sun presented high mortality rate and was not compared to the others. The smallest averages of the analyzed variables, except for height, were observed for the shading of 70%, indicating that this treatment is not advisable for the production of seedlings of this species in nursery. The best condition for planting the seedlings appears to be in open areas with shading of 30 to 50%, since its natural occurrence is not at full exposure.

1987-01-01

A study was performed to determine whether the use of Kevlar cassettes in the neonatal intensive care nursery would reduce radiation exposure to patients. The radiation dose to the neonates was measured by using thermoluminescent dosimeters. In addition, the attenuation of the Kevlar cassettes and the sensitivity of the film-screen combination were compared with the previously used system. The greatest radiation reduction using a mobile X-ray unit was 27%; based on sensitivity measurements, the theoretical reduction averaged 38%. The reduction in radiation exposure resulted from reduced attenuation by the Kevlar cassette

Throat Colonization of Neonatal Nursery Staff by Ureaplasma urealyticum: an Infection Control or Occupational Health Consideration?

Full Text Available Very low birth weight infants often have protracted respiratory tract colonization with Ureaplasma urealyticum. To determine whether prolonged contact with very low birth weight infants resulted in higher rates of upper respiratory tract colonization with this organism for caregivers, throat swabs for U urealyticum culture were obtained from medical, nursing and other support staff working in the neonatal intensive care and level II nurseries at the Health Sciences Centre and the St Boniface Hospital in Winnipeg, Manitoba. Throat colonization by U urealyticum was demonstrated in 7.3% (95% ci 0 to 15.6% of 41 nurses working in the intensive care nurseries but in none of the 48 nurses working in other locations or the 66 other individuals tested (P=0.02. However, throat colonization was not significantly higher among the neonatal intensive care nurses than among the women delivering at one of the study institutions. Close contact with very low birth weight infants appears to constitute a minimal risk for increased throat colonization with U urealyticum among hospital staff members.

Full Text Available Quality and healthy fish seed is the prerequisite for sustainable aquaculture. A major challenge to the expansion of aquaculture production is the outbreak of diseases. Disease induced mortality is a serious issue for the fish seed industry. The immature immune system in fish makes the early developmental stages more susceptible to infectious diseases. Common fish diseases in hatcheries and in early rearing systems are caused by protozoan, ciliates, myxosporodians, worms, opportunistic bacteria and fungi. Production of healthy fish seed and survivality depends on the proper health management, maintenance of good water quality, proper nutrition and application of biosecurity measures. The paper highlighted the different types of diseases, causative agents and their prevention and control measures in fish hatcheries and nurseries. [Fundam Appl Agric 2017; 2(3.000: 311-316

2017-12-15

Endophytic and rhizosphere actinobacteria isolated from the root system of 1-year-old grafted Vitis vinifera plants were evaluated for their activities against fungi that cause grapevine trunk diseases. A total of 58 endophytic and 94 rhizosphere isolates were tested. Based on an in vitro bioassay, 15.5% of the endophytic isolates and 30.8% of the rhizosphere isolates exhibited antifungal activity against the fungal pathogen Diplodia seriata , whereas 13.8% of the endophytic isolates and 16.0% of the rhizosphere isolates showed antifungal activity against Dactylonectria macrodidyma (formerly Ilyonectria macrodidyma ). The strains which showed the greatest in vitro efficacy against both pathogens were further analyzed for their ability to inhibit the growth of Phaeomoniella chlamydospora and Phaeoacremonium minimum (formerly Phaeoacremonium aleophilum ). Based on their antifungal activity, three rhizosphere isolates and three endophytic isolates were applied on grafts in an open-root field nursery in a 3-year trial. The field trial led to the identification of one endophytic strain, Streptomyces sp. VV/E1, and two rhizosphere isolates, Streptomyces sp. VV/R1 and Streptomyces sp. VV/R4, which significantly reduced the infection rates produced by the fungal pathogens Dactylonectria sp., Ilyonectria sp., P. chlamydospora , and P. minimum , all of which cause young grapevine decline. The VV/R1 and VV/R4 isolates also significantly reduced the mortality level of grafted plants in the nursery. This study shows that certain actinobacteria could represent a promising new tool for controlling fungal trunk pathogens that infect grapevine plants through the root system in nurseries. IMPORTANCE Grapevine trunk diseases are a major threat to the wine and grape industry worldwide. They cause a significant reduction in yields as well as in grape quality, and they can even cause plant death. Trunk diseases are caused by fungal pathogens that enter through pruning wounds and/or the

Acquiring seabed, landform or other topographic data in the field of marine ecology has a pivotal role in defining and mapping key marine habitats. However, accessibility for this kind of data with a high level of detail for very shallow and inaccessible marine habitats has been often challenging, time consuming. Spatial and temporal coverage often has to be compromised to make more cost effective the monitoring routine. Nowadays, emerging technologies, can overcome many of these constraints. Here we describe a recent development in remote sensing based on a small unmanned drone (UAVs) that produce very fine scale maps of fish nursery areas. This technology is simple to use, inexpensive, and timely in producing aerial photographs of marine areas. Both technical details regarding aerial photos acquisition (drone and camera settings) and post processing workflow (3D model generation with Structure From Motion algorithm and photo-stitching) are given. Finally by applying modern algorithm of semi-automatic image analysis and classification (Maximum Likelihood, ECHO and Object-based Image Analysis) we compared the results of three thematic maps of nursery area for juvenile sparid fishes, highlighting the potential of this method in mapping and monitoring coastal marine habitats.

Full Text Available The paper discusses the concept, definition and classification of nursery rhymes, and how they are processed. Rhymes are 'short children's songs that serve to counting children at play, which at the same time can be very suitable for developing a sense of rhythm' (Pedagogical Lexicon, 1996, pp. 56. There are several types of nursery rhymes and their classification according to different criteria. They can be classified according to form and content, as well as whether their authors are children or adults. The criterion of understanding classifies them into rhymes rational sense, irrational - meaningless, and rhymes with a partial sense (see examples of rhymes at Milenkovic & Dragojevic, 2009. According to an embodiment - the musical component rhymes are classified in the speaking which develops a sense of rhythm and sung, whose melodic movement of the highest in the fourth volume.

Full Text Available Indicators of growth and condition were used to compare the habitat quality of nurseries of juvenile sole (Solea solea L. in the Bay of Biscay, based on one survey in 2000. The four biological indicators are poorly correlated with each other, suggesting that no single measure may give an adequate description of fish health and of its habitat’s quality. Growth indicators showed significant differences between northern and southern areas. Juveniles from the two southernmost nurseries, the Gironde estuary and the Pertuis Antioche, displayed significant lower otolith increment widths and mean sizes. These differences were inversely related to water temperature and unrelated to genetic or age differences, and are unlikely to be due to limiting trophic conditions in the nurseries. Hence, they may be considered in terms of differences in habitat quality and potential anthropogenic impacts. Condition indices do not show this north-south pattern but highlight low condition values in the Pertuis Antioche. Short-term and fluctuating biochemical indicators such as RNA/DNA ratios appeared to be unreliable over a long-term study, while morphometric indices seemed to be relevant, complementary indicators as they integrate the whole juvenile life-history of sole in the nurseries. The growth and condition indices of juveniles in September 2000 from nursery grounds exposed to the Erika oil spill in December 1999 were relatively high. These results lead us to suggest that there was no obvious impact of this event on the health of juvenile sole and on the quality of the exposed nursery grounds a few months after the event.

We conducted an independent evaluation of the "Teens and Toddlers" intervention. Our randomized trial examined effects on self-reported last sex without contraception, >1 episode of sex without contraception in previous 3 months, expectation of teenage parenthood and youth development score, plus secondary outcomes among 449 at-risk girls age 13/14 in England. The intervention involves 18-20 weekly sessions in pre-school nurseries. Response rates were 95% post-intervention and 91% one year later. At follow-up two, there was no evidence of intervention benefits for primary outcomes and a positive impact for our secondary outcome, low self-esteem. At follow-up one, there was no evidence of benefits for our primary outcomes but evidence of benefits for our secondary outcomes: low self-esteem; low sexual health knowledge; and difficulty discussing the contraceptive pill. The intervention should be refined, with a clearer logic model and more emphasis on sex education, and re-evaluated. Copyright © 2013 The Foundation for Professionals in Services for Adolescents.

Pinus tree plays a pivotal role in commercial revenue generation, domestic lives of rural communities and sustaining of climate of Azad Kashmir. Pinus grows in forest as wild species but due to harsh environmental parameters it is also cultivated in nurseries for propagation and plantation. In this research, injurious impacts of mycofloral diversity on seed germination of Pinus roxburghii Sarg. in nature (forest) and nurseries were explored from different localities of Azad Kashmir, Pakistan. In the analysis two protocols viz., blotter method (BM) and agar plate method (APM) were employed and 11 fungal species of nine genera were isolated. APM was found better (66a ± +-0.32) than BM (60a ± 0.09). The prevalence of different isolated taxa was as: Aspergillus niger (42.75%), Aspergillus flavus (24.0%), Botrytis sp (14.25%), Botryosphaeria sp. (17.75%), Cladosporium cladosporioides (32.75%), Drechslera sp. (5.75%), Fusarium sp. (47.50%), Penecillium sp. (7.25%), Rhizopus stolonifer (11.50%), Rhizopus oryzae (13.0%) and Mucor sp.(7.0%). Pathogenicity analysis depicted that Fusarium was the most harmful (15.75e ± 0.54), followed by Aspergillus flavus (20.50d ± 0.32), Aspergillus niger (25.75c ± 0.42) and Rhizopus sp. (35.75b ± 0.12). Different pathogenicity results of analyzed fungal species were found in different areas and it was highest in Muzaffarabad (52.0%), Kotli (45.6%), Samahni (42.4 %) and least in Bhimber (36.0 %). Radical length (mm) of Pinus roxburghii was severely affected by Aspergillus flavus (46.6a ± 0.44) in Muzaffarabad, Rhizopus sp. (44.1a ± 0.72) in Samahni, Fusarium sp.( 42.5a ± 0.28) in Kotali, Aspergillus niger (37.8a ± 0.44) in Samahni, respectively. The tested species showed that plumule length (mm) of samples was most retarded in Muzaffarbad (37.98%) and least affected in Mirpur (24.58%). The results depict that fungi do cause damage to seed germination and growth of seedlings in nature and nurseries and these findings will be useful

Full Text Available Oil palm (Elaeis guineensis Jacq is one of Indonesia's mainstay plantation commodities and plays an important role for the national economy. Oil palm and plantations managed by state-owned enterprises, this is due to the increasing demand for palm oil in the industrial market. With the continuous development of oil palm plantations so that the provision of seeds should be considered because the success of planting in the field and the production of production is highly dependent on the quality of the seeds of oil palm plants used. Efforts that can be done to accelerate the growth of seeds Main Nursery is to provide NPK fertilizer and growth regulatory substances (ZPT Hantu that can help the absorption of nutrients and accelerate the growth of vegetative plants. The aim of this research is to get the interaction of ZPT Hantu concentration and NPK fertilizer dosage which give the best influence to the growth of oil palm seed (Elaeis guineensis Jacq in Main-nursery. The experiment was conducted experimentally with factorial Randomized Design (RAL, consisting of 2 factors ie H factor is ZPT Hantu and N factor is NPK fertilizer (16:16:16 which each consist of 3 levels. Thus obtained 9 treatment combinations with 3 replications. The observed data were analyzed by Duncan's multipoint test and Duncan's multiplexed test of 5%. Test of ZPT Hantu and NPK fertilizer significantly affect the growth of oil palm seedlings in Main Nursery that is on the parameters of seed height, stem diameter, leaf number and leaf area, whereas the combination of both only on bar diameter parameters that gives a real effect, with best treatment is combination giving ZPT Hantu 2 cc / l water and NPK 20 grams / plant.

Full Text Available Airports consume significant amounts of water which can be compared to the volume consumed by mid-size cities, thus practices aimed at reducing water consumption are important and necessar y. The objective of this study was to assess the reuse potential of sewage effluent produced at a mid-size international airport for nursery irri gation. The sewage treatment system consisted of a facultative pond followed by a constructed wetland, which were monitored during one hydrological year a nd the parameters COD, pH, solids, nitrogen, phosphorus and Escherichia coli we re analyzed. Removal efficiencies of 85% and 91% were achieved for C OD and solids, respectively. Removal efficiencies for ammonia nitrogen a nd total phosphorus were 77% and 59%, respectively. In terms of E. coli concen tration, the treated effluent met the recommendations by the World Health Organization for reuse in irrigation with the advantage of providing high levels of residual nutrient. The ornamental species Impatiens walleriana was irrigated with treated sewage effluent and plant growth characteristics were evalua ted. The experiment showed that reuse can enhance plant growth without signi ficantly affecting leaf tissue and soil characteristics. This study highlighted th e importance of simple technologies for sewage treatment especially in count ries which still do not present great investment in sanitation and proved that effluent reuse for landscape irrigation can provide great savings of water and financial resources for airport environments.

Adults' perceptions of children with disruptive behaviour disorders (DBDs), which usually interfere with socialization and referral of children to mental health services, might differ according to the child's sex. Given the importance of (a) the interactions between these children and their educators, and (b) early identification and referral, the impact of the child's sex on adults' perceptions is an important factor to consider. To examine the role of gender-related expectations in the identification and referral of childhood DBDs by trainee nursery teachers. One hundred and fifty-eight female trainee nursery teachers (mean age = 20 years) at the Department of Early Childhood Education in Athens. Trainee nursery teachers' perceptions of male and female children with DBDs were explored using a Greek version of the Parental Account of the Causes of Childhood Problems Questionnaire. Eighty-one participants answered questions about a set of disruptive behaviours ascribed to a boy and 77 about the same behaviour ascribed to a girl. DBDs ascribed to girls were considered to be no more severe or of greater concern than those ascribed to boys. Judgements of severity were related to concern in the same way for boys and girls. However, DBDs were regarded as less typical for girls than boys. The child's sex affected trainee teachers' judgements of typicality, but not severity, of children's behaviour problems. The implications of this finding for socialization practices and referral attitudes are discussed.

Conversion to aquaculture affects the provision of important ecosystem services provided by mangrove ecosystems, and this effect depends strongly on the location of the conversion. We introduce in a bio-economic mathematical programming model relevant spatial elements that affect the provision of the nursery habitat service of mangroves: (1) direct or indirect connection of mangroves to watercourses; (2) the spatial allocation of aquaculture ponds; and (3) the presence of non-linear relations between mangrove extent and juvenile recruitment to wild shrimp populations. By tracing out the production possibilities frontier of wild and cultivated shrimp, the model assesses the role of spatial information in the trade-off between aquaculture and the nursery habitat function using spatial elements relevant to our model of a mangrove area in Ca Mau Province, Viet Nam. Results show that where mangrove forests have to coexist with shrimp aquaculture ponds, the inclusion of specific spatial information on ecosystem functions in considerations of land allocation can achieve aquaculture benefits while largely preserving the economic benefits generated by the nursery habitat function. However, if spatial criteria are ignored, ill-advised land allocation decisions can easily lead to a collapse of the mangrove's nursery function. Copyright © 2014 Elsevier Ltd. All rights reserved.

This work was conducted at a private nursery in Kafr El-Sheikh governorate to investigate the bioconversion of rice straw into a soil-like substrate (SLS) by Phanerochaete chrysosporium and Trichoderma hazianum and the possibility of using rice straw compost in ornamental nurseries as a partial or total replacement of coconut peat (CP) and vermiculite (V) in the growing medium. The results showed that rice straw could be treated better by aerobic fermentation. The authors used five mixtures as follows: (1) Control (CP+V at 1:1 v/v), (2) SLS (100%), (3) SLS+CP (1:1 v/v), (4) SLS+V (1:1 v/v), and (5) SLS+CP+V (1:1:1 v/v/v). Data were recorded as seedling height, no. of leaves, shoot fresh and dry weights, root length and root fresh and dry weights in order to assess the quality of both transplants of Althea rosea (hollyhock) and Calendula officinalis (scotch marigold). Hollyhock seedlings grown in medium containing a mixture of SLS+CP+V displayed quality traits similar to those recorded from the control treatment, while scotch marigold seedlings in the same medium followed the control medium in quality.

Fluconazole is a triazole antifungal agent that is widely used in the nursery. It is available in both intravenous and oral formulation, and is active against most of the fungal pathogens that require treatment when retrieved from culture samples in neonatal intensive care units. Although clinical use has been wide for over 15 years, there have been small safety and efficacy studies completed in young infants. Randomised clinical trials assessing effectiveness of this agent in prevention of systemic fungal infections in neonates have been published in the last decade, and one large additional randomised study has been recently completed. Nevertheless, a certain degree of uncertainty still exists regarding the kinetics and appropriate dosing of this agent in premature and term infants, as well as regarding safety. Areas of poignant debate include the feasibility of loading dose strategies, appropriate dosages in the early days of life in the different subgroups of preterm infants, and long-term safety of fluconazole administered in prophylaxis during the first weeks of life in extremely premature infants. This paper reviews the most recent evidence on fluconazole and its role in the NICU settings. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Oral language skills are a critical foundation for literacy and more generally for educational success. The current study shows that oral language skills can be improved by providing suitable additional help to children with language difficulties in the early stages of formal education. We conducted a randomized controlled trial with 394 children in England, comparing a 30-week oral language intervention programme starting in nursery (N = 132) with a 20-week version of the same programme starting in Reception (N = 133). The intervention groups were compared to an untreated waiting control group (N = 129). The programmes were delivered by trained teaching assistants (TAs) working in the children's schools/nurseries. All testers were blind to group allocation. Both the 20- and 30-week programmes produced improvements on primary outcome measures of oral language skill compared to the untreated control group. Effect sizes were small to moderate (20-week programme: d = .21; 30-week programme: d = .30) immediately following the intervention and were maintained at follow-up 6 months later. The difference in improvement between the 20-week and 30-week programmes was not statistically significant. Neither programme produced statistically significant improvements in children's early word reading or reading comprehension skills (secondary outcome measures). This study provides further evidence that oral language interventions can be delivered successfully by trained TAs to children with oral language difficulties in nursery and Reception classes. The methods evaluated have potentially important policy implications for early education. © 2017 Association for Child and Adolescent Mental Health.

Highlights: ► Cupressus Blue Ice was tolerant to 100 mg kg −1 Cd exposure. ► Cd was mainly stabilized in epidermis other than cortex plus stele of root. ► Negligible Cd in transplanted roots was released into bulk soil. ► Usefulness and limitations of the new approach were evaluated. - Abstract: Disposal of heavy metal contaminated biomass after phytoremediation is still unfeasible. This paper presents a viable phyto-extraction approach in which metals in contaminated soils are stabilized by nursery stocks before transplantation for greening. In this respect, two pot-experiments are reported comparing seven nursery stocks species exposed to different Cd levels. The first experiment revealed that Cd was mainly stabilized in the roots of all species studied. Greater amounts of Cd were accumulated in the epidermis than cortex plus stele. Cupressus Blue Ice showed greatest tolerance to the 100 and 200 mg kg −1 Cd stresses. The second experiment additionally evaluated the possible risk of Cd release after transplanting the Cd treated plants into uncontaminated soil. After 120 days of transplantation, the relatively trace amounts of Cd in the roots of Euonymus japonicus, Pittosporum tobira and C. Blue Ice had either been partially transferred into the shoots or released into the soil. The highest Cd concentration increase in bulk soil (0.428 mg kg −1 ), however, was much lower than the environmental quality standard for soils of China (1 mg kg −1 ). The potential effectiveness of this technique in the use of Cd-contaminated soil and further investigation needed in the field trials were also evaluated.

A notification from a laboratory concerning the detection of Campylobacter jejuni in a 6-year-old boy initiated the investigation carried out by the health authorities from Stendal district, in order to explain the morbidity rate caused by the germ. The day after the boy's pediatrician informed about a visit to a farm, which was confirmed by the head of the nursery. She told the health authorities about the consumption of raw milk during their visit at the farm.The following days more children fell sick. Within 10 days the total number of diseased children was 21. The health authorities asked for stool samples of the diseased children, nursery nurses and the head of the farm since raw milk presents a potential cause of infection. The health authorities together with the Saxony-Anhalt State Office for Consumer Protection conducted a retrospective cohort study. The aim was to explain the association between the exposure from raw milk consumption and the occurrence of the disease from C. jejuni. Based on a questionnaire data about the food and milk intake at the nursery and at home and about the trip to the farm were collected. 91% of the children's cohort and 86% of the adults' cohort were captured.The exposed group at risk showed a higher risk of falling ill than the group, which was not exposed. The risk factor raw milk explained the difference. Furthermore, the analysis of milk samples taken by the district veterinary office from 2 cows and from the farm's tank was able to detect the germs. The correlation of the illness, the consumption of raw milk, the detection of C. jejuni in the samples taken from the children and the samples taken from the cows was evident. Based on the case the health authorities recommended that heads of nurseries as well as heads of dairy farming in the district of Stendal needed to be advised on raw milk. Nurseries are still allowed to take trips to farms. However, raw animal derivates including milk must not be consumed. © Georg Thieme

The sentinel tree nursery as an early warning system for pathway risk assessment: Fungal pathogens associated with Chinese woody plants commonly shipped to Europe.

Directory of Open Access Journals (Sweden)

Anna Maria Vettraino

Full Text Available Introduction of and invasion by alien plant pathogens represents the main cause of emerging infectious diseases affecting domesticated and wild plant species worldwide. The trade in living plants is the most common pathway of introduction. Many of the alien tree pathogens recently introduced into Europe were not previously included on any quarantine lists. To help determine the potential risk of pest introduction through trading of ornamental plants, a sentinel nursery was established in Beijing, China in 2008. The sentinel nursery planting included four of the most common ornamental woody species shipped to Europe including Ilex cornuta var. fortunae, Zelkova schneideriana, Fraxinus chinensis and Buxus microphylla. Symptoms developing on these species within the sentinel nursery were detected in 2013 and consisted of necrotic spots on leaves, canker and stem necrosis, shoot blight and shoot necrosis. Fungi associated with the trees and their symptoms included Alternaria alternata detected from all hosts; Diaporthe liquidambaris and Diaporthe capsici from bark and leaf necrosis of Zelkova schneideriana; Botryosphaeria dothidea and Nothophoma quercina from stem cankers on Fraxinus chinensis and leaf necrosis on Ilex cornuta; and Pseudonectria foliicola from leaf necrosis on Buxus microphylla. Next generation sequencing analysis from asymptomatic tissues detected eighteen OTU's at species level among which some taxa had not been previously recorded in Europe. These results clearly demonstrate that looking at trees of internationally traded species in the region of origin can reveal the presence of potentially harmful organisms of major forestry, landscape or crop trees. Results of this study also provide an indication as to how some disease agents can be introduced using pathways other than the co-generic hosts. Hence, sentinel nurseries represent one potential mechanism to address the current lack of knowledge about pests in the countries from

2017-03-01

Marine habitat function has been typically investigated in terms of biogeochemical regulation but rarely in terms of population renewal, which is mainly controlled by recruitment dynamics. The recruitment phase is crucial for organisms with a bentho-pelagic life cycle, such as bivalves, and it regulates the population renewal success. This study provides new insight on the role of temperate benthic habitats on bivalve recruitment, as a function of nursery areas. Six dominant benthic habitats of the Chausey archipelago (Normandy, France) were studied. In each habitat, bivalve recruit assemblages were described at the end of two reproductive seasons. Furthermore, Ostrea edulis juveniles were immerged on each habitat during two months to compare growth performances and feeding status, estimated by fatty acid composition. Recruit assemblages differ from each habitat according to sediment grain-size composition and bathymetrical levels. Subtidal habitats, and especially Crepidula fornicata banks and Glycymeris glycymeris coarse sands, supported the highest species abundance and richness of recruits. All O. edulis juveniles fed on the same trophic resources but digestive glands of juveniles from C. fornicata banks were more concentrated in total fatty acids than those from subtidal G. glycymeris coarse sands and maerl banks. Our results depict the key role of subtidal and structured habitats, composed of ecosystem engineers, in enhancing bivalve recruitment and extending the bivalve population renewal. This study suggests that the crucial role of these habitats as bivalve nurseries must be integrated in management perspectives. 2-column fitting image. 1-column fitting image.

The present experiment evaluated the standard and progressive rootstocks for the pear trees in combination with the Asian varieties of P. pyrifolia Nakai. a P. ussuriensis Maxim. in comparison with the control variety ‘Conference’ P. communis L. The evaluation was focused on such properties as affinity, growth of the tree propagated by budding, thickness of the root crown at the rootstock and the root suckering. Their interactions were tested statistically. The highest values of affinity within the nursery were achieved with the following rootstocks: ‘BET’ (96.6%, ‘FOX 11’ (95.5 %, and ‘MA’ (94.4 %. ‘Hosui’ was identified as the variety with the greatest growing capacity, with an average gain of 1238.2 mm. The most supported variety growth was exhibited by the ‘FOX 11’ rootstock, with an average gain of the trees propagated by budding of 1388.8 mm. The growth intensity itself was demonstrated most in the thickness of the root crown of the ‘BET’ (P. betulifolia rootstock, namely 15.8 mm. The rootstock that exhibited the strongest root suckering was also ‘BET’ with 6.2 suckers per rootstock. The identified differences between the varieties and rootstocks were confirmed as statistically significant or even highly statistically significant.

Full Text Available Abstract: British children enter school younger than their European counterparts. Research suggests that this disadvantages boys who may be unready for formal literacy instruction.This longitudinal study explores the effect of age of entry to school on boys’ reading development, focussing on attitudes and beliefs. Data from 60 summer-born boys, divided into two cohorts, was collected on three occasions: before entry to Year One, end of Year One and end of Year Two. Comparisons were drawn between 31 boys with part-time nursery education before Year One, and 29 with full-time Reception class experience. This paper presents data collected at Time One. Employing both quantitative and qualitative methodologies the study explores how beliefs about and attitudes towards reading emerge in the context of these contrasting early years settings. Implications of the findings are considered in the context of policies and trends in age of entry to school.

Ectomycorrhizal fungi (ECMF) play an important role in forest ecosystems, often mitigating stress factors and increasing seedling performance. The aim of this study was to investigate the effects of a nursery inoculation on Pinus pinaster growth and on the fungal communities established when reforesting burned areas. Inoculated P. pinaster saplings showed 1.5-fold higher stem height than the non-inoculated controls after a 5 year growth period, suggesting that fungal inoculation could potentiate tree growth in the field. Ordination analysis revealed the presence of different ECMF communities on both plots. Among the nursery-inoculated fungi, Laccaria sp., Rhizopogon sp., Suillus bovinus and Pisolithus sp. were detected on inoculated Pinus saplings on both sampling periods, indicating that they persisted after field establishment. Other fungi were also detected in the inoculated plants. Phialocephala sp. was found on the first assessment, while Terfezia sp. was detected on both sampling periods. Laccaria sp. and Rhizopogon sp. were identified in the control saplings, belonging however to different species than those found in the inoculated plot. Inocybe sp., Thelephora sp. and Paxillus involutus were present on both sampling periods in the non-inoculated plots. The results suggest that ECMF inoculation at nursery stage can benefit plant growth after transplantation to a post-fire site and that the inoculated fungi can persist in the field. This approach has great potential as a biotechnological tool to aid in the reforestation of burned areas.

Temperate estuaries are nursery areas for economically important fisheries resources. The common jellyfish Aurelia aurita is a resident species in many of these areas, where it can reach high abundances. This work aimed to determine the potential for predation of A. aurita on zooplanktonic organisms and early life stages of fishes, measuring feeding rates at concentrations that mimic those occurring for zooplankton, fish eggs and larvae in an estuarine nursery area. A set of experiments was aimed at determining the feeding selectivity of jellyfish when offered a mixture of fish eggs and larvae and wild plankton. Clearance rates varied markedly with prey availability and concentrations. When given mixtures of different prey types, jellyfish preferentially elected some taxa (copepods and fish eggs). Data obtained in the laboratory experiments were used to infer the potential impact of jellyfish predation upon zooplankton and ichthyoplankton in the Guadiana estuary (Southern Iberia). Repeated sampling of zooplankton, fish eggs and medusae was undertaken during the summer season of 2011. Abundance determinations were combined with experimentally estimated clearance rates of individual medusa to infer the potential jellyfish-induced mortality on prey in the area. In June and early August jellyfish-induced mortality rates were very high, and half-life times (t1/2) were consequently short for the zooplankton and ichthyoplankton. Although the potentially overestimation of our feeding rates typical of confined laboratory experiments, the results show high ingestion and clearance rates at high temperatures, typical from summer condition, and results also suggest that either by predation on early life stages of fish, or by competition for food resources, jellyfish may have a significant impact on estuarine communities and its nursery function.

The chemical composition of fish otoliths reflects that of the water masses that they inhabit. Otolith elemental compositions can, therefore, be used as natural tags to discriminate among habitats. However, for retrospective habitat identification to be valid and reliable for any adult, irrespective of its age, significant differences in environmental conditions, and therefore otolith signatures, must be temporally stable within each habitat, otherwise connectivity studies have to be carried out by matching year-classes to the corresponding annual fingerprints. This study investigated how various different combinations of chemical elements in otoliths could distinguish, over three separate years, between four coastal lagoon habitats used annually as nurseries by gilthead sea bream (Sparus aurata L.) in the Gulf of Lions (NW Mediterranean). A series of nine elements were measured in otoliths of 301 S. aurata juveniles collected in the four lagoons in 2008, 2010 and 2011. Percentages of correct re-assignment of juveniles to their lagoon of origin were calculated with the Random Forest classification method, considering every possible combination of elements. This revealed both spatial and temporal variations in accuracy of habitat identification, with correct re-assignment to each lagoon ranging from 44 to 99% depending on the year and the lagoon. There were also annual differences in the combination of elements that provided the best discrimination among the lagoons. Despite this, when the data from the three years were pooled, a combination of eight elements (B, Ba, Cu, Li, Mg, Rb, Sr and Y) provided greater than 70% correct re-assignment to each single lagoon, with a multi-annual global accuracy of 79%. When considering the years separately, discrimination accuracy with these elemental fingerprints was above 90% for 2008 and 2010. It decreased to 61% in 2011, when unusually heavy rainfall occurred, which presumably reduced chemical differences among several of the

I am 40 years old but my average age is 4. Who am I? The answer is the CERN nursery school, located near Gate A on the Meyrin site. This year's traditional end-of-year party on 24 June was a lot more lively than usual. To mark the school's fortieth birthday in style, the teachers dressed up in pretty, floating costumes, a clown on stilts was in attendance, to the delight of a fascinated crowd of children, and balloons were released into the sky. Dozens of balloons were released into the sky to mark the CERN nursery school's 40th Anniversary.Standing on stilts and performing a juggling act, the clown was the highlight of the evening. In 1965, when it was created on the initiative of a group of parents, the nursery school consisted of a single class that was open in the mornings only and was held in a room located outside the CERN site. The Staff Association took up the reins right from the start and is still running the school today. The school went from strength to strength. "Even at the beginning, there was...

Full Text Available Ethephon alone and in a mixture with inorganic defoliants was used to defoliate apple nursery trees of three cultivars: Yellow Transparent, McIntosh and Jonathan. The mixture of ethephon with copper sulphate or magnesium chlorate defoliated the trees better than ethophon or inorganic defoliants used seperately in twice as high concentrations as in a mixture. The tress defoliated with the mixtures of defoliants suffered less from frost injury than those treated with only the inorganic defoliants.

Full Text Available This project assessed the significance of Pigeon Creek, San Salvador, Bahamas as a nursery habitat for coral reef fishes. Pigeon Creek’s perimeter is lined with mangrove and limestone bedrock. The bottom is sand or seagrass and ranges in depth from exposed at low tide to a 3-m deep, tide-scoured channel. In June 2006 and January 2007, fish were counted and their maturity was recorded while sampling 112 of 309 possible 50-m transects along the perimeter of the Pigeon Creek. Excluding silversides (Atherinidae, 52% of fish counted, six families each comprised >1% of the total abundance (Scaridae/parrotfishes, 35.3%; Lutjanidae/snappers, 23.9%; Haemulidae/grunts, 21.0%; Gerreidae/mojarras, 8.5%; Pomacentridae/damselfishes, 6.1%; Labridae/wrasses, 2.4%. There were few differences in effort-adjusted counts among habitats (mangrove, bedrock, mixed, sections (north, middle, southwest and seasons (summer 2006 and winter 2007. Red Mangrove (Rhizophora mangle, covering 68% of the perimeter was where 62% of the fish were counted. Snappers, grunts and parrotfishes are important food fishes and significant families in terms of reef ecology around San Salvador. Mangrove was the most important habitat for snappers and grunts; bedrock was most important for parrotfishes. The southwest section was important for snappers, grunts and parrotfishes, the north section for grunts and parrotfishes, and the middle section for snappers. Among the non-silverside fish counted, 91.2% were juveniles. These results suggest that Pigeon Creek is an important nursery for the coral reefs surrounding San Salvador and should be protected from potential disturbances.

This pilot study provides the first empirical test of the concept of "Angels in the Nursery" by examining whether childhood memories of benevolent caregiving experiences protect against heightened levels of psychopathology in high-risk mothers. The study hypothesized that (a) elaborated childhood memories of feeling loved by a caregiver ("angel memories") would moderate adulthood posttraumatic stress disorder (PTSD) symptoms in mothers with childhood maltreatment histories, and (b) spontaneous traumatic intrusions ("ghost memories") would mediate childhood maltreatment and adulthood PTSD symptoms. Participants were 54 mothers (M = 32.79 years, SD = 8.91; 59.2% African American, 13.0% Caucasian, 5.6% Latina, 22.2% biracial/multiracial) who completed standardized assessments of childhood maltreatment and adulthood PTSD symptoms, and a novel instrument, the Angels in the Nursery Interview ("Angels Interview," Van Horn, Lieberman, & Harris, 2008). Results showed that angel memories significantly moderated childhood maltreatment and adulthood PTSD symptoms, consistent with a protective effect. Higher levels of ghost memories during the Angels Interview were significantly associated with more extensive childhood maltreatment, but did not mediate maltreatment and PTSD symptoms. Findings indicate that the Angels Interview can identify pathogenic intrusions rooted in childhood maltreatment and protective factors to promote maternal mental health and buffer the intergenerational transmission of trauma. © 2017 Michigan Association for Infant Mental Health.

Coastal ecosystems, which provide numerous essential ecological functions for fish, are threatened by the proliferation of green macroalgae that significantly modify habitat conditions in intertidal areas. Understanding the influence of green tides on the nursery function of these ecosystems is essential to determine their potential effects on fish recruitment success. In this study, the influence of green tides on juvenile fish was examined in an intertidal sandy beach area, the Bay of Saint-Brieuc (Northwestern France), during two annual cycles of green tides with varying levels of intensity. The responses of three nursery-dependent fish species, the pelagic Sprattus sprattus (L.), the demersal Dicentrarchus labrax (L.) and the benthic Pleuronectes platessa L., were analysed to determine the effects of green tides according to species-specific habitat niche and behaviour. The responses to this perturbation were investigated based on habitat selection and a comparison of individual performance between a control and an impacted site. Several indices on different integrative scales were examined to evaluate these responses (antioxidant defence capacity, muscle total lipid, morphometric condition and growth). Based on these analyses, green tides affect juvenile fish differently according to macroalgal density and species-specific tolerance, which is linked to their capacity to move and to their distribution in the water column. A decreasing gradient of sensitivity was observed from benthic to demersal and pelagic fish species. At low densities of green macroalgae, the three species stayed at the impacted site and the growth of plaice was reduced. At medium macroalgal densities, plaice disappeared from the impacted site and the growth of sea bass and the muscle total lipid content of sprat were reduced. Finally, when high macroalgal densities were reached, none of the studied species were captured at the impacted site. Hence, sites affected by green tides are less

Full Text Available Juvenile rig (Mustelus lenticulatus were internally tagged with acoustic transmitters and tracked with acoustic receivers deployed throughout two arms of Porirua Harbour, a small (7 km(2 estuary in New Zealand. Ten rig were tracked for up to four months during summer-autumn to determine their spatial and temporal use of the habitat. The overall goal was to estimate the size of Marine Protected Areas required to protect rig nursery areas from direct human impacts. Rig showed clear site preferences, but those preferences varied among rig and over time. They spent most of their time in large basins and on shallow sand and mud flats around the margins, and avoided deep channels. Habitat range increased during autumn for many of the rig. Only one shark spent time in both harbour arms, indicating that there was little movement between the two. Rig home ranges were 2-7 km(2, suggesting that an effective MPA would need to cover the entire Porirua Harbour. They moved to outer harbour sites following some high river flow rates, and most left the harbour permanently during or soon after a river spike, suggesting that they were avoiding low salinity water. Rig showed strong diel movements during summer, although the diel pattern weakened in autumn. Persistent use of the same day and night sites indicates that diel movements are directed rather than random. Further research is required to determine the sizes of rig home ranges in larger harbours where nursery habitat is more extensive. Marine Protected Areas do not control land-based impacts such as accelerated sedimentation and heavy metal pollution, so integration of marine and terrestrial management tools across a range of government agencies is essential to fully protect nursery areas.

Settling characteristics of nursery pig manure and nutrient estimation by the hydrometer method.

Science.gov (United States)

Zhu, Jun; Ndegwa, Pius M; Zhang, Zhijian

2003-05-01

The hydrometer method to measure manure specific gravity and subsequently relate it to manure nutrient contents was examined in this study. It was found that this method might be improved in estimation accuracy if only manure from a single growth stage of pigs was used (e.g., nursery pig manure used here). The total solids (TS) content of the test manure was well correlated with the total nitrogen (TN) and total phosphorus (TP) concentrations in the manure, with highly significant correlation coefficients of 0.9944 and 0.9873, respectively. Also observed were good linear correlations between the TN and TP contents and the manure specific gravity (correlation coefficients: 0.9836 and 0.9843, respectively). These correlations were much better than those reported by past researchers, in which lumped data for pigs at different growing stages were used. It may therefore be inferred that developing different linear equations for pigs at different ages should improve the accuracy in manure nutrient estimation using a hydrometer. Also, the error of using the hydrometer method to estimate manure TN and TP was found to increase, from +/- 10% to +/- 50%, with the decrease in TN (from 700 ppm to 100 ppm) and TP (from 130 ppm to 30 ppm) concentrations in the manure. The estimation errors for TN and TP may be larger than 50% if the total solids content is below 0.5%. In addition, the rapid settling of solids has long been considered characteristic of swine manure; however, in this study, the solids settling property appeared to be quite poor for nursery pig manure in that no conspicuous settling occurred after the manure was left statically for 5 hours. This information has not been reported elsewhere in the literature and may need further research to verify.

Tetrastigma rafflesiae (Miq.) Planch is one of the sole host species of parasitic plants in the family Rafflesiaceae. A study was conducted in order to propagate this species using vegetative propagation. This propagation technique was done using stem cuttings and was conducted in the nursery at the National University of Malaysia (UKM). The propagation medium were made using four types of soil nursery mixtures of topsoil, organic matter and sand (7:3:1, 3:2:1, 2:1:1 and 1:1:1), mixture of topsoil, organic matter, sand and three different hormones treatments (0:0:IAA, 0:0:IBA and 0:0:NAA) and without any hormone treatment in basic soil (1:0:0, 0:1:0 and 0:0:1) was treated as a control. Approximately, stem cutting was used in 15 cm length. The base of each cutting was treated with root powdered hormones before being planted in soil. After 180 days of planting, the high number of leaf quantity (>12 leaves) was produced from stem cutting planted in 3:2:1 soil mixtures and the same results was obtained from stem cutting more than 15 cm to 18.78 cm in length, significantly. Soil mixture with 7:3:1 has significantly increased the leaf chlorophyll contents (10.22 nm) and also increased in leaf area index (16.375 cm²). Treatment hormones do not have any significant result in this study. The study has showed that T. rafflesiae can be propagated using cuttings as alternative source of planting materials for conservation purposes.

Asymmetrical nature of the Trollius-Chiastocheta interaction: insights into the evolution of nursery pollination systems.

The mutualistic versus antagonistic nature of an interaction is defined by costs and benefits of each partner, which may vary depending on the environment. Contrasting with this dynamic view, several pollination interactions are considered as strictly obligate and mutualistic. Here, we focus on the interaction between Trollius europaeus and Chiastocheta flies, considered as a specialized and obligate nursery pollination system - the flies are thought to be exclusive pollinators of the plant and their larvae develop only in T. europaeus fruits. In this system, features such as the globelike flower shape are claimed to have evolved in a coevolutionary context. We examine the specificity of this pollination system and measure traits related to offspring fitness in isolated T. europaeus populations, in some of which Chiastocheta flies have gone extinct. We hypothesize that if this interaction is specific and obligate, the plant should experience dramatic drop in its relative fitness in the absence of Chiastocheta. Contrasting with this hypothesis, T. europaeus populations without flies demonstrate a similar relative fitness to those with the flies present, contradicting the putative obligatory nature of this pollination system. It also agrees with our observation that many other insects also visit and carry pollen among T. europaeus flowers. We propose that the interaction could have evolved through maximization of by-product benefits of the Chiastocheta visits, through the male flower function, and selection on floral traits by the most effective pollinator. We argue this mechanism is also central in the evolution of other nursery pollination systems.

Ichthyoplankton in a southern african surf zone: Nursery area for the postlarvae of estuarine associated fish species?

Whitfield, A. K.

1989-12-01

The surf zone ichthyoplankton of Swartvlei Bay was studied between February 1986 and June 1987, with particular emphasis on its potential role as a nursery area for estuarine associated marine fish species. Larvae and/or postlarvae of 16 families were identified from the surf zone, with the Gobiidae, Soleidae, Sparidae and Mugilidae comprising 85·7% of all teleosts sampled. The postlarvae of several taxa (including the six most common species), which utilize the Swartvlei estuary as a juvenile nursery area, were abundant in the surf zone. Conversely, species which are common in nearshore marine waters as juveniles and adults, but seldom enter estuaries, totalled less than 8% of the surf zone ichthyoplankton assemblage. Larval and postlarval densities peaked during summer when water temperatures exceeded 19°C and the estuary mouth was open. Concentrations of ichthyoplankton were highest at those sampling stations closest to the estuary mouth during the summer period. Diel changes in total catches revealed no significant difference between day and night densities; but of the four major taxa, the Mugilidae and Sparidae tended to be more abundant during the day, the Gobiidae at night and the Soleidae showed no distinct pattern. Results from a 24 h sampling session indicated that tidal phase may also be important in governing ichthyoplankton abundance in the surf zone.

Full Text Available Abstract. The study was carried out in the period 2010 – 2012 in a nursery field established on the territory of the Fruit-Growing Institute, Plovdiv. The effect of the combined soil-applied herbicide metolachlor + oxyfluorfen (Metofen and the contact soil herbicide with foliar activity flumioxazine (Pledge 50 WP on the vegetative habits of 'Nonpareil' almond cultivar grafted on almond seedling rootstock was evaluated. In the period 15-25 March, before beginning of vegetation, soil herbicides were applied in the row strip in the second-year nursery field. The following variants were included in the study: 1. Control (untreated, handweeded; 2. Metofen – 120 ml/da; 3. Metofen – 240 ml/da; 4. Pledge 50 WP – 8.0 g/da; 5. Pledge 50 WP – 20.0 g/da. The effect of the herbicides on weed infestation and on the vegetative habits of the cultivar/rootstock combination 'Nonpareil'/almond seedling rootstock was followed up. The results showed that the herbicides applied at the tested rates had a good control on weed infestation and the herbicide activity continued for 3.5-4 months. That makes it possible to eliminate the competitive impact of weeds on the development of the grafted trees for 4-5 months after beginning of vegetation. Visual symptoms of phytotoxicity (chlorosis or necrosis in the leaves and shoots or an obvious suppression of the development of the grafted trees in the treated variants were not established. A depressing effect on growth of the grafted trees was reported after treatment with Metofen. The contact herbicide with soil and foliar activity Pledge 50 WP – 8.0 g/da can be applied for weed control in a second-year nursery field of almond trees grafted on bitter almond seedling rootstock.

The study objectives were to determine nursery phase feeder space allowance effects on pig performance when double stocked and, second, to determine feeder space allowance and dried distillers grains with solubles (DDGS) inclusion level effects on pig performance and nutrient digestibility during the growing-finishing phase. This study was performed on the same group of pigs within a commercial wean-finish system. For the nursery phase, a completely randomized design was used to compare 3 feeder space allowance treatments (2.1, 2.5, and 2.9 cm/pig). A total of 3,720 pigs were randomly allotted to same-sex pens (10 feeders/treatment) housing 62 pigs/pen. Thirty 7-hole, double-sided feeders were utilized in the study. Differing linear feeder space treatments were established by blocking off sections for the nursery and grow-finish portions of this experiment. All pigs were provided equal floor space (0.26 m2/pig). In the grow-finish phase, a total of 1,860 pigs (n = 60 pens) were utilized in a 2 × 3 factorial design with 3 feeder space allowances (4.1, 4.9, or 5.7 cm/pig) and 2 dietary DDGS treatments (30% [D30] or 60% [D60]). Fecal and diet samples were collected and analyzed to estimate apparent total tract digestibility percentage (ATTD %). In the nursery portion of the trial, there was no feeder space treatment effect on ADG, ADFI, or feed efficiency (P > 0.10) from weaning to d 56 postweaning or during any weigh period. In the grow-finish portion of the trial, feeder space allowance and DDGS inclusion level did not affect ADG, ADFI, or feed efficiency (P > 0.05) from d 57 postweaning to market. Pigs fed the D30 diet had greater HCW, percent yield, and loin depth than those on the D60 diet (P feeder space allowance did not impact pig performance during the nursery or grow-finish production phases. Inclusion of DDGS at higher levels will decrease ADFI but not ADG or efficiency when isocaloric diets are fed. The inclusion level of DDGS does impact HCW and percent

Diet control is one of the important factors in the prevention of dental caries because food functions as substratum for fermentation and, consequently, for the formation of the organic acids that demineralize the tooth surface. This study aims to descriptively assess school diet and the associated caries-preventive methods applied to children in all municipal nursery schools of a Brazilian city (Aragatuba/SP). For this, a questionnaire with open and closed questions was used. The results showed that all schools serve school meal, which is composed mainly of sugar, carbohydrates, and proteins. The students enjoy the meal very much because for most of them, the meal served at school is the only source of food. It was observed that 90% of the schools offer other kinds of food besides the main school meal. The snacks served such as cakes, white hominy, and milk fudge are composed of sweet and highly cariogenic foods. It was also verified that in 13.30% of the schools, the daily supervised dental hygiene, an important procedure that should not be neglected, is not carried out. This procedure introduces the children to healthy habits that are added to those acquired in the family environment. It was concluded that the school diet is potentially cariogenic and, in association with the lack of daily dental hygiene, this potential may become even higher.

Full Text Available In May and October 2010–2012, mycological studies were conducted on 10 cultivars of rhododendron bushes growing in containers in the nursery of ornamental plants. Out of 3000 specimens of infested leaf fragments, 2566 fungal colonies belonging to 41 species were isolated. The following species colonizing the leaves and causing their necrosis were extracted in the largest number of colonies: Alternaria alternata, Aspergillus niger, Epicoccum nigrum, Humicola grisea, Pestalotiopsis sydowiana, Phoma pomorum, Sordaria fimicola, Trichoderma koningii, Trichoderma polysporum, Truncatella truncata, Umbelopsis isabellina and others. The research showed that the micromycetes colonies colonizing and damaging rhododendron leaves varied in species composition and number of colonies in different years and at different times. The study determined which rhododendron cultivars were characterized by good health and which had the greatest susceptibility to infection by micromycetes.

To measure how much very low birth-weight infants are exposed to chest X-rays during nursery, skin doses were calculated using phantoms under the same condition as that used in chest X-rays. Skin doses obtained were multiplied by the number of X-rays performed in 86 very low birth-weight infants (mean birth weight+-SD, 1163.0+-232.8 g; mean gestational age+-SD, 29.3+-3.0 week). Exposure doses per film ranged from 4.9 to 14.4 mR, with a mean dose of 6.1+-2.0 mR. Exposure doses per neonate ranged from 6.3 to 794.3 mR, with a mean dose of 170.4+-151.5 mR. The number of films per neonate ranged from one to 107, with a mean of 28.0+-24.9. Eighty-seven percent of X-rays were performed when the body weight was 1,500 g or less. Fourteen patients received 300 mR or more that may be the potential dose of radiation effects. (Namekawa, K)

Staghorn coral, Acropora cervicornis, is a threatened species and the primary focus of western Atlantic reef restoration efforts to date. We compared linear extension, calcification rate, and skeletal density of nursery-raised A. cervicornis branches reared for 6 months either on blocks attached to substratum or hanging from PVC trees in the water column. We demonstrate that branches grown on the substratum had significantly higher skeletal density, measured using computerized tomography, and lower linear extension rates compared to water-column fragments. Calcification rates determined with buoyant weighing were not statistically different between the two grow-out methods, but did vary among coral genotypes. Whereas skeletal density and extension rates were plastic traits that depended on grow-out method, calcification rate was conserved. Our results show that the two rearing methods generate the same amount of calcium carbonate skeleton but produce colonies with different skeletal characteristics and suggest that there is genetically based variability in coral calcification performance.

Nursery of Giants

Hidden behind a shroud of dust in the constellation Cygnus is a stellar nursery called DR21, which is giving birth to some of the most massive stars in our galaxy. Visible light images reveal no trace of this interstellar cauldron because of heavy dust obscuration. In fact, visible light is attenuated in DR21 by a factor of more than 10,000,000,000,000,000,000,000,000,000,000,000,000,000 (ten thousand trillion heptillion). New images from NASA's Spitzer Space Telescope allow us to peek behind the cosmic veil and pinpoint one of the most massive natal stars yet seen in our Milky Way galaxy. The never-before-seen star is 100,000 times as bright as the Sun. Also revealed for the first time is a powerful outflow of hot gas emanating from this star and bursting through a giant molecular cloud. This image is a large-scale mosaic assembled from individual photographs obtained with the InfraRed Array Camera (IRAC) aboard Spitzer. The image covers an area about two times that of a full moon. The mosaic is a composite of images obtained at mid-infrared wavelengths of 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8 microns (red). The brightest infrared cloud near the top center corresponds to DR21, which presumably contains a cluster of newly forming stars at a distance of 10,000 light-years. Protruding out from DR21 toward the bottom left of the image is a gaseous outflow (green), containing both carbon monoxide and molecular hydrogen. Data from the Spitzer spectrograph, which breaks light into its constituent individual wavelengths, indicate the presence of hot steam formed as the outflow heats the surrounding molecular gas. Outflows are physical signatures of processes that create supersonic beams, or jets, of gas. They are usually accompanied by discs of material around the new star, which likely contain the materials from which future planetary systems are formed. Additional newborn stars, depicted in green, can be seen surrounding the DR21 region

Casuarina equisetifolia Forst. is a tree crop that provides fuel wood, land reclamation, dune stabilization, and scaffolding for construction, shelter belts, and pulp and paper production. C. equisetifolia fixes atmospheric nitrogen through a symbiotic relationship with Frankia, a soil bacterium of the actinobacteria group. The roots of C. equisetifolia produce root nodules where the bacteria fix atmospheric nitrogen, which is an essential nutrient for all plant metabolic activities. However, rooted stem cuttings of elite clones of C. equisetifolia by vegetative propagation is being planted by the farmers of Pondicherry as costeffective method. As the vegetative propagation method uses inert material (vermiculite) for rooting there is no chance for Frankia association. Therefore after planting of these stocks the farmers are applying 150 kg of di-ammonium phosphate (DAP)/acre/year. To overcome this fertilizer usage, the Frankia-inoculated rooted stem cuttings were propagated under nursery conditions and transplanted in the nutrient-deficient soils of Karaikal, Pondicherry (India), in this study. Under nursery experiments the growth and biomass of C. equisetifolia rooted stem cuttings inoculated with Frankia showed 3 times higher growth and biomass than uninoculated control. These stocks were transplanted and monitored for their growth and survival for 1 year in the nutrient-deficient farm land. The results showed that the rooted stem cuttings of C. equisetifolia significantly improved growth in height (8.8 m), stem girth (9.6 cm) and tissue nitrogen content (3.3 mg g-1) than uninoculated controls. The soil nutrient status was also improved due to inoculation of Frankia.

Full Text Available Education in Brazil have expanded the debate concerning the quality offered, as well as being a constitutional guarantee, there are the State's efforts in the allocation of financial resources annually. In the case of Basic Education was created in 2007 the Direct Money in School Program (DMSP that the Union transfers financial assistance to state and local public schools, and encourage widespread participation in resource management. Thus, the study’s objective was to investigate how civil society involved in the management of public resources of TSA, in a descriptive research with a quantitative and qualitative approach. The data collection was a documentary research: 29 accounts rendered digitized Direct Money in School Program (DMSP from schools and day care centers located in the municipality of Rio de Janeiro for the year 2012. Consolidating research, we sought to understand the perception of the Director of School / Day Care and President of the Community Council-School on the subject employing a questionnaire. In addition to the Audit Services scanned the TSA was checked for evidence of compliance with the principle of accountability and encouraging the social control in the electronic media. The results show the need to improve the participation of civil society, given that this study found that schools/nurseries do not provide the program information on official websites, minimizing transparency, and there is the existence of oversight failures in the assessment of benefits accounts and composition of the Councils.

This study has developed a learning kit for the prevention of domestic burns in childhood. The main objective was to trial an educational package for children (nursery and primary classes), for the prevention of burns, to be implemented through education in schools. The educational kit comprises posters, information leaflets, comic books, and pre and post education evaluation materials for school children, parents and teachers. Recipients of the preliminary study were the students of nine schools in the eight Italian cities where Burn Centers are located. In order to reach the target groups of children, it was necessary to identify the most effective communication strategy to convey the burn prevention message. For nursery school children, it was not possible to use tools with written texts alone, as they were not yet literate. Moreover, even for older children, it was necessary to find an attractive tool to catch their attention and interest, promoting the understanding and memorization of lessons learned. The most suitable means was found to be comic strips, allowing the messages to be conveyed through images as well as words. A total of 370 children (195 from nurseries and 175 from primary schools) participated in the trial of the educational kit. Overall, for every environment represented in the evaluation table, the ability to recognize the dangers among both the pre-school and primary school children increased significantly after the training activity. In conclusion, the educational kit has been positively assessed.
