Spatial and ontogenetic variation in growth of nursery-bound juvenile lemon sharks, Negaprion brevirostris: a comparison of two age-assigning techniques

We compared growth rates of the lemon shark, Negaprion brevirostris, from Bimini, Bahamas and the Marquesas Keys (MK), Florida using data obtained in a multi-year annual census. We marked new neonate and juvenile sharks with unique electronic identity tags in Bimini and in the MK we tagged neonate and juvenile sharks. Sharks were tagged with tiny, subcutaneous transponders, a type of tagging thought to cause little, if any disruption to normal growth patterns when compared to conventional external tagging. Within the first 2 years of this project, no age data were recorded for sharks caught for the first time in Bimini. Therefore, we applied and tested two methods of age analysis: ( 1) a modified 'minimum convex polygon' method and ( 2) a new age-assigning method, the 'cut-off technique'. The cut-off technique proved to be the more suitable one, enabling us to identify the age of 134 of the 642 previously unknown aged sharks. This maximised the usable growth data included in our analysis. Annual absolute growth rates of juvenile, nursery-bound lemon sharks were almost constant for the two Bimini nurseries and can be best described by a simple linear model ( growth data was only available for age-0 sharks in the MK). Annual absolute growth for age-0 sharks was much greater in the MK than in either the North Sound (NS) and Shark Land (SL) at Bimini. Growth of SL sharks was significantly faster during the first 2 years of life than of the sharks in the NS population. However, in MK, only growth in the first year was considered to be reliably estimated due to low recapture rates. Analyses indicated no significant differences in growth rates between males and females for any area.

Isolation of polymorphic tetranucleotide microsatellite markers for the ornate nursery frog Cophixalus ornatus

We have isolated 18 polymorphic microsatellite loci for Cophixalus ornatus from genomic libraries enriched for (AAAG)(n), (AACC)(n) and (AAGG)(n) repetitive elements. The number of alleles ranges from five to 22 per locus with the observed heterozygosity ranging from 0.10 to 0.92. These markers will be useful for the analysis of population structure in C. ornatus and testing alternative models of speciation.

Wage matters & globalization: South Florida's low-wage immigrant plant nursery workers and business protectionism in the age of neoliberalism

Ornamental plant production in the State of Florida is an anomaly with respect to current theories of globalization and particularly their explanation of the employment of low-wage, immigrant labor. Those theories dictate that unskilled jobs that do not need to be performed within highly developed countries are outsourced to where labor is cheaper and more flexible. However, the State of Florida remains an important site of ornamental plant production in the US amidst a global economic environment of outsourcing and transnational corporate expansion. This dissertation relies on 50 semi-structured interviews with insiders of the Florida plant nursery industry, focus groups, and participant observation to explain how US trade, labor, and migration policy-making at local levels are not removed from larger global processes taking place in the world since the 1970s. In Florida, elite market players of the plant nursery industry have been able to resist global trends in free trade, operating instead in a protected market. They have done this by appealing to scientific justifications and through arbitrary implementations of neoliberal ideology that keeps small and middle range business alive, while maintaining a seemingly endless supply of marginalized and exploited low-wage, immigrant workers.^

A nursery for seamen: life histories from the St. John's Royal Naval Hospital Cemetery, Newfoundland

A cemetery associated with the St. John’s Royal Naval Hospital, NL (~1725-1825) was partially excavated in 1979, uncovering the skeletal remains of at least 21 individuals. Isotopic analyses (δ¹³Cvpdb, δ¹⁵Nair, δ¹⁸Ovpdb, and ⁸⁷Sr/⁸⁶Sr) were used to examine the diet and geographic origins of these individuals and compare them with recent results from other British Naval cemeteries. Their origins according to enamel carbonates and ⁸⁷Sr/⁸⁶Sr are mainly consistent with the British Isles and the bone collagen values were largely consistent with naval rations. There was some variability in δ¹⁵Nair and δ¹³Cvpdb values, suggesting different social classes and the consumption of C₄ foods associated with North America. While this study has highlighted deficiencies in the ability of isotopic analyses to define the variability within naval rations, it is the first to examine origins of early modern naval sailors isotopically, as well as the experiences of these sailors within the context of Newfoundland.

Hide, survive and hitch a ride, the dispersal of Antarctic krill into the nursery habitats

Antarctic krill (Euphausia superba), a key species of Southern Ocean food webs plays a central role in ecosystem processes, community dynamics of apex predators and as a commercial fishery target. A decline in krill abundance during the late 20th century in the SW Atlantic sector has been linked to a concomitant decrease in sea ice, based on the hypothesis that sea ice acts as a feeding ground for overwintering larvae. However, evidence supporting this hypothesis has been scarce due to logistical challenges of collecting data in austral winter. Here we report on a winter study that involved diver observations of larval krill in their under-ice environment, ship-based studies of krill, sea ice physical characteristics, and biophysical model analyses of krill-ocean-ice interactions. We present evidence that complex under-ice topography is vital for larval krill in terms of dispersal and advection into high productive nursery habitats, rather than the provision by the ice environment of food. Further, ongoing changes in sea ice will lead to increases in sea-ice regimes favourable for overwintering larval krill but shifting southwards. This will result in ice-free conditions in the SW Atlantic, which will be conducive for enhancing food supplies due to sufficient light and iron availability, thus enhancing larvae development and growth. However, the associated impact on dispersal and advection may lead to a net shift in krill from the SW Atlantic to regions further east by the eastward flowing ACC and the northern branch of the Weddell Gyre, with profound consequences for the Southern Ocean pelagic ecosystem.

Effect of diatom supplementation during the nursery rearing of Litopenaeus vannamei (Boone, 1931) in a heterotrophic culture system

Bio-floc shrimp culture systems have been investigated in an attempt to optimize water use and prevent the discharge of effluent into the environment. The importance of microalgae in maintaining water quality and nutrition of the shrimp is well known in conventional systems; however, its maintenance amid bio-flocs and its role in the shrimp performance in this system are still poorly understood. The aim of this study was to evaluate the contribution of diatoms in the performance of Litopenaeus vannamei reared during the nursery phase in intensive system with minimal water exchange. Shrimp (0.31 ± 0.10 g) were reared among diatoms, bio-flocs and the combination of the two forming the mixture medium. The survival of shrimp was high in all treatments (90–97%). However, the shrimp reared among diatoms showed higher weight gain (P\0.05) and feed conversion ratio significantly more efficient, reaching a value of 0.47. The results indicate the importance of diatoms in bio-floc culture systems and points out to future research in an attempt to maintain a constant presence of these microalgae in culture medium without requiring successive inoculations.

Proposal for linking the school library of the School Education Unit Four Queens in the nursery of J. Francisco Public Library Orlich Tibás Canton, Heredia, Costa Rica

Since classical antiquity, the public library has been the institution that helps people to know their history and face the changes that society increasingly demands. Similarly, school libraries are piloting the learning of children; in them, manage to have their first contact with books, his first great travel stories with dinosaurs, robots, fiction, among others through the stories, legends and knowledge games. School libraries contribute to strengthening reading habits from the earliest years of life.In conducting the research, developed an assessment of the current situation of the two libraries under study, based on the following variables: services, human resources, budget, infrastructure, children's collection, furniture, electronic equipment and audiovisual, recreational interests, needs of information, socio-cultural characteristics and availability. This was achieved through the collection of information externada by children of preschool and junior, mothers or guardians and teachers of the Education Unit of Four Queens and in charge of the School Library Education Unit Four Queens (BEUPCR) and J. Francisco Public Library Orlich (BPFJO).According to the diagnosis and analysis of information, it is shown that the aspects related to personnel, electronic equipment and resources are limited, in addition, there were deficiencies in infrastructure BEUPCR.
