Modos de pensar e de fazer: o cuidado de enfermagem à pessoa com HIV/Aids representado pela equipe de enfermagem

Este estudo propõe uma reflexão acerca do cuidado de enfermagem e suas práticas voltadas à pessoa com HIV/Aids desenvolvido por profissionais da equipe de enfermagem. O objetivo geral foi analisar as representações sociais e as práticas de cuidado de enfermagem a pessoa com HIV/Aids para a equipe de enfermagem que atua no Programa de DST/Aids no Município do Rio de Janeiro. Trata-se de uma pesquisa qualitativa, fundamentada na Teoria das Representações Sociais. Quanto à metodologia este estudo foi desenvolvido com 16 unidades de saúde inseridas no Programa Nacional de DST-Aids do Ministério da Saúde, que prestam assistência a pessoas que vivem com HIV/Aids em nível ambulatorial. Participaram desse estudo 37 profissionais, sendo 20 enfermeiros e 17 técnicos e auxiliares de enfermagem. Os dados foram coletados através de entrevista semiestruturada, tendo sido analisadas através da utilização do software ALCESTE 4.10; e questionário de identificação sócio-profissional, cuja análise de dados foi realizada com estatística descritiva. A partir da análise ALCESTE foram definidas 7 classes, divididas em dois blocos temáticos, sendo o primeiro denominado O HIV/Aids e seus impactos sociais através do olhar da equipe de enfermagem. Este bloco abarcou 3 classes, sendo elas: Preconceito e vulnerabilidade no cotidiano do cuidado de enfermagem de pessoas atingidas pelo HIV/Aids (classe1); As relações familiares e o envolvimento com o HIV/Aids (classe 4) e Memórias sócio profissionais sobre o HIV/Aids (classe 7). O segundo bloco temático denomina-se O HIV/Aids e as práticas de cuidado, e abarca 4 classes da análise, denominadas: A complexidade do atendimento ambulatorial da pessoa com HIV/Aids (classe 2); As práticas de cuidado da equipe de enfermagem e da equipe multiprofissional (classe 3); A educação em saúde como prática do cuidado de enfermagem (classe 5) e Medidas de proteção e biossegurança dos profissionais de enfermagem (classe 6). No primeiro bloco observa-se as representações da doença, os estigmas enfrentados pela pessoa com HIV/Aids, as relações com familiares e profissionais de saúde e as memórias da equipe de enfermagem com relação a doença. Observa-se que mesmo após ter havido mudanças no perfil da doença, as marcas do passado ainda se fazem presentes no cotidiano desses sujeitos, o que se reflete no cuidado de enfermagem, nas relações familiares e na vida em sociedade. O segundo bloco descreve as práticas institucionais e profissionais de cuidado à pessoa com HIV/Aids, observando-se o destaque da autoproteção no cuidado de enfermagem aos sujeitos com HIV/Aids. Também são destacados elementos como o cuidado do outro, tais como o vínculo, a postura acolhedora, o apoio psicológico e o relacionamento interpessoal, que são modalidades reconhecidas como participantes das práticas de cuidado, assim como a educação em saúde. Conclui-se que os diversos conteúdos que compõem as representações sociais e as práticas de cuidado de enfermagem a pessoa com HIV/Aids se apresentam sentimentos, práticas, atitudes, memórias, conceitos e imagens atuais e antigas, com a presença do cuidado instrumental, mas também do cuidado relacional.

A representação social do ser homem para homens heterossexuais e a vulnerabilidade para o HIV/AIDS

Introdução: A Política Nacional de Atenção Integral à Saúde do Homem surge para compreender a singularidade masculina nos seus diversos contextos socioculturais. A política trás, como um dos objetivos, promover, na população masculina, conjuntamente com o Programa Nacional de DST/AIDS, a prevenção e o controle das doenças sexualmente transmissíveis e da infecção pelo HIV. A pesquisa em tela tem por objetivo: Identificar a representação social do ser homem para homens que se referem como heterossexuais; Descrever as práticas sociais e culturais que podem levar o homem a se expor ao HIV; e Analisar a representação social do ser homem e sua relação com a vulnerabilidade para a infecção pelo HIV. Metodologia: Trata-se de uma pesquisa qualitativa, pautada na Teoria das Representações Sociais, realizada no CTA em São Gonçalo, Rio de Janeiro, com a participação de 08 sujeitos, com os quais foram desenvolvidas entrevistas semiestruturadas. Os dados foram analisados através da análise de conteúdo. Resultado: Da análise dos dados surgiram quatro categorias, quais sejam, a representação social do ser homem: imagens, comportamentos e compromissos; O homem ideal e o romantizado: caráter, sucesso, herói e imagem; o homem real: individualismo, apego às máquinas, o jeitinho masculino e a vida sexual; e o universo reificado da aids e a construção do preconceito. A ideia do homem ideal aparece para os sujeitos como aquele que pratica o que é politicamente correto e que, por sua vez, segue as normas da sociedade vigente. Para eles a masculinidade tem como desdobramento a virilidade e o homem é, por natureza, considerado como ser insaciável sexualmente. Os entrevistados apontaram para uma dimensão avaliativa do homem real, como um sujeito individualista e com práticas hedonistas e com uma prática sexual desenfreada. Contudo, a proteção pela infecção ao HIV é representada através da fidelidade conjugal, onde o comportamento sexual considerado adequado serve como imunização contra a infecção. Os sujeitos apresentaram o homem ideal como um ser romantizado, rompendo com o estereótipo que se tem do homem na sociedade, como sujeito duro, infiel e dominador. A partir do estudo constatou-se que os entrevistados possuem uma visão reificada sobre a doença e representam a aids como a doença do outro. Conclusão/Contribuições para enfermagem: A compreensão do homem na atualidade pode nos trazer novas discussões no que diz respeito à construção social do mesmo, assim como suas implicações diante das vulnerabilidades existentes para a infecção pelo HIV/AIDS, a fim de desconstruir mitos e tabus que permeiam a questão cultural do que é ser masculino, para assim, entender esse sujeito no âmbito dos serviços de saúde e trabalhar práticas sociais e sexuais masculinas saudáveis.

Metas de socialização e práticas educativas de mães de crianças com câncer: um estudo comparativo com mães de crianças sem diagnóstico de doença

Sistemas parentais são construídos através das interações no cotidiano dos pais com seus filhos e com base nos padrões culturais vigentes, dentro de um perfil socioeconômico e da história de vida dos indivíduos. Importantes componentes dos sistemas parentais são as metas de socialização e as práticas educativas. As metas de socialização se referem a como os pais desejam que seus filhos sejam no futuro, àquilo que eles esperam que sua criação ajude a promover em seus filhos. Já as práticas educativas são as práticas de comunicar à criança a forma correta com que se espera que ela se comporte. A revisão bibliográfica evidencia que as metas de socialização e práticas educativas são afetadas pelo ambiente cultural dos cuidadores e por variáveis socioeconômicas, mas não há estudos a respeito de possíveis impactos causados por situações de vida particularmente difíceis. A presente dissertação se propôs a examinar as metas de socialização e práticas educativas de mães cujos filhos estão em tratamento oncológico, contrastando-as com as de mães de crianças saudáveis. Nesse sentido, o objetivo estabelecido foi o de investigar se havia particularidades nas metas de socialização e formas de cuidado de mães com filhos que tenham câncer devido à situação específica vivida de um tratamento oncológico. Hipotetizou-se que a vivência da experiência do câncer e a inserção em uma instituição de tratamento, no caso, o Instituto Nacional do Câncer (INCA), teriam impacto no sistema de cuidados e metas parentais. Participaram deste estudo 20 mães de crianças de três a cinco anos que estavam em tratamento oncológico no INCA e 20 mães de crianças na mesma faixa etária sem problemas de saúde diagnosticados. Todas assinaram o Termo de Consentimento Livre e Esclarecido. Foram aplicados os formulários "Dados de identificação" e "Dados sociodemográficos", e o Questionário de Metas de Socialização. Foi também realizada com as mães uma entrevista semiestruturada, com questões abertas que buscaram investigar práticas educativas. A análise de dados contemplou uma parte de análises quantitativas em que os dados foram tratados descritivamente (médias, percentuais etc.) e empregados testes não-paramétricos para comparação entre os grupos de mães. Análises qualitativas, voltadas para as respostas ao questionário de metas de socialização e à entrevista sobre práticas de cuidado educativas foram realizadas através do método de análise de conteúdo temático-categorial. Encontrou-se que as metas de socialização das mães de crianças em tratamento oncológico apresentaram diferenças em relação às das mães de crianças sem diagnóstico de doença, refletindo uma tendência mais individualista. Também foram encontradas diferenças entre os dois grupos nas ações para atingir as metas, sendo visto um uso menor da estratégia educar e orientar por parte do grupo das mães de crianças em tratamento no INCA, refletindo uma tendência mais pragmática. Quanto às práticas educativas não foram encontradas diferenças significativas entre os dois grupos. Espera-se que esse estudo traga contribuições para a formulação de programas de intervenção, para pais e cuidadores, através da melhor compreensão das metas e práticas maternas utilizadas nesta situação particular e de grande dificuldade para as crianças e suas famílias

Our living oceans: report on the status of U.S. living marine resources, 6th edition

The National Marine Fisheries Service (NMFS) is dedicated to the stewardship of living marine resources (LMR’s). This is accomplished through science-based conservation and management, and the promotion of healthy ecosystems. As a steward, NMFS has an obligation to conserve, protect, and manage these resources in a way that ensures their continuation as functioning components of healthy marine ecosystems, affords economic opportunities, and enhances the quality of life for the American public. In addition to its responsibilities within the U.S. Exclusive Economic Zone (EEZ), NMFS plays a supportive and advisory role in the management of LMR’s in the coastal areas under state jurisdiction and provides scientific and policy leadership in the international arena. NMFS also implements international measures for the conservation and management of LMR’s, as appropriate.NMFS receives its stewardship responsibilities under a number of Federal laws. These include the Nation’s primary fisheries law, the Magnuson Fishery Conservation and Management Act. This law was first passed in 1976, later reauthorized as the Magnuson-Stevens Fishery Conservation and Management Act in 1996, and reauthorized again on 12 January 2007 as the Magnuson-Stevens Fishery Conservation and Management Reauthorization Act (MSRA). The MSRA mandates strong action to conserve and manage fishery resources and requires NMFS to end overfishing by 2010 in all U.S. commercial and recreational fisheries, rebuild all overfished stocks, and conserve essential fish habitat.

Marine Fisheries Stock Assessment Improvement Plan: report of the National Marine Fisheries Service National Task Force for Improving Fish Stock Assessments

This report argues for greatly increased resources in terms of data collection facilities and staff to collect, process, and analyze the data, and to communicate the results, in order for NMFS to fulfill its mandate to conserve and manage marine resources. In fact, the authors of this report had great difficulty defining the "ideal" situation to which fisheries stock assessments and management should aspire. One of the primary objectives of fisheries management is to develop sustainable harvest policies that minimize the risks of overfishing both target species and associated species. This can be achieved in a wide spectrum of ways, ranging between the following two extremes. The first is to implement only simple management measures with correspondingly simple assessment demands, which will usually mean setting fishing mortality targets at relatively low levels in order to reduce the risk of unknowingly overfishing or driving ecosystems towards undesirable system states. The second is to expand existing data collection and analysis programs to provide an adequate knowledge base that can support higher fishing mortality targets while still ensuring low risk to target and associated species and ecosystems. However, defining "adequate" is difficult, especially when scientists have not even identified all marine species, and information on catches, abundances, and life histories of many target species, and most associated species, is sparse. Increasing calls from the public, stakeholders, and the scientific community to implement ecosystem-based stock assessment and management make it even more difficult to define "adequate," especially when "ecosystem-based management" is itself not well-defined. In attempting to describe the data collection and assessment needs for the latter, the authors took a pragmatic approach, rather than trying to estimate the resources required to develop a knowledge base about the fine-scale detailed distributions, abundances, and associations of all marine species. Thus, the specified resource requirements will not meet the expectations of some stakeholders. In addition, the Stock Assessment Improvement Plan is designed to be complementary to other related plans, and therefore does not duplicate the resource requirements detailed in those plans, except as otherwise noted.

A pilot survey of deepwater coral/sponge assemblages and their susceptibility to fishing/harvest impacts at the Olympic Coast National Marine Sanctuary (OCNMS). Cruise report for NOAA Ship McARTHUR II Cruise AR-04-04: Leg 2 (June 1-12, 2004)

The offshore shelf and canyon habitats of the OCNMS are areas of high primary productivity and biodiversity that support extensive groundfish fisheries. Recent acoustic surveys conducted in these waters have indicated the presence of hard-bottom substrates believed to harbor unique deep-sea coral and sponge assemblages. Such fauna are often associated with shallow tropical waters, however an increasing number of studies around the world have recorded them in deeper, cold-water habitats in both northern and southern latitudes. These habitats are of tremendous value as sites of recruitment for commercially important fishes. Yet, ironically, studies have shown how the gear used in offshore demersal fishing, as well as other commercial operations on the seafloor, can cause severe physical disturbances to resident benthic fauna. Due to their exposed structure, slow growth and recruitment rates, and long life spans, deep-sea corals and sponges may be especially vulnerable to such disturbances, requiring very long periods to recover. Potential effects of fishing and other commercial operations in such critical habitats, and the need to define appropriate strategies for the protection of these resources, have been identified as a high-priority management issue for the sanctuary.

A biogeographic assessment of the Channel Islands National Marine Sanctuary: a review of boundary expansion concepts for NOAA’s National Marine Sanctuary Program

The priority management goal of the National Marine Sanctuaries Program (NMSP) is to protect marine ecosystems and biodiversity. This goal requires an understanding of broad-scale ecological relationships and linkages between marine resources and physical oceanography to support an ecosystem management approach. The Channel Islands National Marine Sanctuary (CINMS) is currently reviewing its management plan and investigating boundary expansion. A management plan study area (henceforth, Study Area) was described that extends from the current boundary north to the mainland, and extends north to Point Sal and south to Point Dume. Six additional boundary concepts were developed that vary in area and include the majority of the Study Area. The NMSP and CINMS partnered with NOAA’s National Centers for Coastal Ocean Science Biogeography Team to conduct a biogeographic assessment to characterize marine resources and oceanographic patterns within and adjacent to the sanctuary. This assessment includes a suite of quantitative spatial and statistical analyses that characterize biological and oceanographic patterns in the marine region from Point Sal to the U.S.-Mexico border. These data were analyzed using an index which evaluates an ecological “cost-benefit” within the proposed boundary concepts and the Study Area. The sanctuary resides in a dynamic setting where two oceanographic regimes meet. Cold northern waters mix with warm southern waters around the Channel Islands creating an area of transition that strongly influences the regions oceanography. In turn, these processes drive the biological distributions within the region. This assessment analyzes bathymetry, benthic substrate, bathymetric life-zones, sea surface temperature, primary production, currents, submerged aquatic vegetation, and kelp in the context of broad-scale patterns and relative to the proposed boundary concepts and the Study Area. Boundary cost-benefit results for these parameters were variable due to their dynamic nature; however, when analyzed in composite the Study Area and Boundary Concept 2 were considered the most favorable. Biological data were collected from numerous resource agencies and university scientists for this assessment. Fish and invertebrate trawl data were used to characterize community structure. Habitat suitability models were developed for 15 species of macroinvertebrates and 11 species of fish that have significant ecological, commercial, or recreational importance in the region and general patterns of ichthyoplankton distribution are described. Six surveys of ship and plane at-sea surveys were used to model marine bird diversity from Point Arena to the U.S.-Mexico border. Additional surveys were utilized to estimate density and colony counts for nine bird species. Critical habitat for western snowy plover and the location of California least tern breeding pairs were also analyzed. At-sea surveys were also used to describe the distribution of 14 species of cetaceans and five species of pinnipeds. Boundary concept cost-benefit indices revealed that Boundary Concept 2 and the Study Area were most favorable for the majority of the species-specific analyses. Boundary Concept 3 was most favorable for bird diversity across the region. Inadequate spatial resolution for fish and invertebrate community data and incompatible sampling effort information for bird and mammal data precluded boundary cost-benefit analysis.

Watershed restoration: a guide for citizen involvement in California.

There is nothing mysterious about how coastal rivers, their estuaries, and their relationship with the sea all work to satisfy many of our greatest needs, including drinkable water, fish and shellfish, and soils essential for sustaining the production of food and fiber. Nor are the methods that have proved successful in the protection and restoration of watershed health difficult to understand. It is difficult, however, to imagine how we are to survive without healthy watersheds. Each watershed along California’s coast shows signs of increasing abuse from road construction and maintenance, livestock grazing, residential development, timber harvesting, and a dozen other human activities. In some cases whole streams have simply been wiped away. This document has been created to guide and support every person in the community, from homemaker to elected official, who wants her or his watershed to provide clean water, harvestable fish resources and other proof that life in the watershed cannot only be maintained but also enjoyed. It is based on years of experience with watershed protection and restoration in California. If citizen involvement is to be effective, it must draw not only on scientific knowledge but also on an understanding of how to translate individual views into commitments and capable group action. This guide briefly reviews the condition of California’s coastal watersheds, identifies the kinds of concerns that have led citizens to successful watershed protection efforts, explains why citizen, in addition to government, effort is essential for watershed protection and restoration to succeed, and puts in the reader’s hands both the technical and organizational “tools of the trade” in the hope that those who use this guide will be encouraged to join in efforts to make their watershed serve this and future generations better.

Benthic habitats of Buck Island Reef National Monument

NOAA’s Center for Coastal Monitoring and Assessment’s Biogeography Branch has mapped and characterized large portions of the coral reef ecosystems inside the U.S. coastal and territorial waters, including the U.S. Caribbean. The complementary protocols used in these efforts have enabled scientists and managers to quantitatively compare different marine ecosystems in tropical U.S. waters. The Biogeography Branch used these same general protocols to generate three seamless habitat maps of the Bank/Shelf (i.e., from 0 ≤50 meters) and the Bank/Shelf Escarpment (i.e., from 50 ≤1,000 meters and from 1,000 ≤ 1,830 meters) inside Buck Island Reef National Monument (BIRNM). While this mapping effort marks the fourth time that the shallow-water habitats of BIRNM have been mapped, it is the first time habitats deeper than 30 meters (m) have been characterized. Consequently, this habitat map provides information on the distribution of mesophotic and deep-water coral reef ecosystems and serves as a spatial baseline for monitoring change in the Monument. A benthic habitat map was developed for approximately 74.3 square kilometers or 98% of the BIRNM using a combination of semi-automated and manual classification methods. The remaining 2% was not mapped due to lack of imagery in the western part of the Monument at depths ranging from 1,000 to 1,400 meters. Habitats were interpreted from orthophotographs, LiDAR (Light Detection and Ranging) imagery and four different types of MBES (Multibeam Echosounder) imagery. Three minimum mapping units (MMUs) (100, 1,000 and 5,000 square meters) were used because of the wide range of depths present in the Monument. The majority of the area that was characterized was deeper than 30 m on the Bank/Shelf Escarpment. This escarpment area was dominated by uncolonized sand which transitioned to mud as depth increased. Bedrock was exposed in some areas of the escarpment, where steep slopes prevented sediment deposition. Mesophotic corals were seen in the underwater video, but were too sparsely distributed to be reliably mapped from the source imagery. Habitats on the Bank/Shelf were much more variable than those seen on the Bank/Shelf Escarpment. The majority of this shelf area was comprised of coral reef and hardbottom habitat dominated by various forms of turf, fleshy, coralline or filamentous algae. Even though algae was the dominant biological cover type, nearly a quarter (24.3%) of the Monument’s Bank/Shelf benthos hosted a cover of 10%-<50% live coral. In total, 198 unique combinations of habitat classes describing the geography, geology and biology of the sea-floor were identified from the three types of imagery listed above. No thematic accuracy assessment was conducted for areas deeper than about 50 meters, most of which was located in the Bank/Shelf Escarpment. The thematic accuracy of classes in waters shallower than approximately 50 meters ranged from 81.4% to 94.4%. These thematic accuracies are similar to those reported for other NOAA benthic habitat mapping efforts in St. John (>80%), the Main Eight Hawaiian Islands (>84.0%) and the Republic of Palau (>80.0%). These digital maps products can be used with confidence by scientists and resource managers for a multitude of different applications, including structuring monitoring programs, supporting management decisions, and establishing and managing marine conservation areas. The final deliverables for this project, including the benthic habitat maps, source imagery and in situ field data, are available to the public on a NOAA Biogeography Branch website (http://ccma.nos.noaa.gov/ecosystems/coralreef/stcroix.aspx) and through an interactive, web-based map application (http://ccma.nos.noaa.gov/explorer/biomapper/biomapper.html?id=BUIS). This report documents the process and methods used to create the shallow to deep-water benthic habitat maps for BIRNM. Chapter 1 provides a short introduction to BIRNM, including its history, marine life and ongoing research activities. Chapter 2 describes the benthic habitat classification scheme used to partition the different habitats into ecologically relevant groups. Chapter 3 explains the steps required to create a benthic habitat map using a combination of semi-automated and visual classification techniques. Chapter 4 details the steps used in the accuracy assessment and reports on the thematic accuracy of the final shallow-water map. Chapter 5 summarizes the type and abundance of each habitat class found inside BIRNM, how these habitats compare to past habitat maps and outlines how these new habitat maps may be used to inform future management activities.

Support for integrated ecosystem assessments of NOAA’s National Estuarine Research Reserve System (NERRS): assessment of ecological condition and stressor impacts in subtidal waters of the Sapelo Island National Estuarine Research Reserve

A study was conducted in June 2009 to assess the current status of ecological condition and potential human-health risks throughout subtidal estuarine waters of the Sapelo Island National Estuarine Research Reserve (SINERR) along the coast of Georgia. Samples were collected for multiple indicators of ecosystem condition, including water quality (dissolved oxygen, salinity, temperature, pH, nutrients and chlorophyll, suspended solids, fecal coliform bacteria and coliphages), sediment quality (granulometry, organic matter content, chemical contaminant concentrations), biological condition (diversity and abundance of benthic fauna, fish tissue contaminant levels and pathologies), and human dimensions (fish-tissue contaminant levels relative to human-health consumption limits, various aesthetic properties). Use of a probabilistic sampling design facilitated the calculation of statistics to estimate the spatial extent of the Reserve classified according to various categories (i.e., Good, Fair, Poor) of ecological condition relative to established thresholds of these indicators, where available. Overall, the majority of subtidal habitat in the SINERR appeared to be healthy, with over half (56.7 %) of the Reserve area having water quality, sediment quality, and benthic biological condition indicators rated in the healthy to intermediate range of corresponding guideline thresholds. None of the stations sampled had one or more indicators in all three categories rated as poor/degraded. While these results are encouraging, it should be noted that one or more indicators were rated as poor/degraded in at least one of the three categories over 40% of the Reserve study area, represented by 12 of the 30 stations sampled. Although measures of fish tissue chemical contamination were not included in any of the above estimates, a number of trace metals, pesticides, polybrominated diphenyl ethers (PBDEs), and polychlorinated biphenyls (PCBs) were found at low yet detectable levels in some fish at stations where fish were caught. Levels of mercury and total PCBs in some fish specimens fell within EPA guideline values considered safe, given a consumption rate of no more than four fish meals per month. Moreover, PCB congener profiles in sediments and fish in the SINERR exhibit a relative abundance of higher-chlorinated homologs which are uniquely characteristic of Aroclor 1268. It has been well-documented that sediments and fish in the creeks and marshes near the LCP Chemicals Superfund site, near Brunswick, Georgia, also display this congener pattern associated with Aroclor 1268, a highly chlorinated mixture of PCBs used extensively at a chlor-alkali plant that was in operation at the LCP site from 1955-1994. This report provides results suggesting that the protected habitats lying within the boundaries of the SINERR may be experiencing the effects of a legacy of chemical contamination at a site over 40km away. These effects, as well as other potential stressors associated with increased development of nearby coastal areas, underscore the importance of establishing baseline ecological conditions that can be used to track potential changes in the future and to guide management and stewardship of the otherwise relatively unspoiled ecosystems of the SINERR.

Report of 2009 Bottlenose Dolphin (Tursiops truncatus) Life History Workshop: expanding network capabilities

The Virginia Aquarium & Marine Science Center Foundation’s Stranding Response Program (VAQS) was awarded a grant in 2008 to conduct life history analysis on over 10 years of Tursiops truncatus teeth and gonad samples from stranded animals in Virginia. A major part of this collaborative grant included a workshop involving life historians from Hubbs-Sea World Research Institute (HSWRI), NOS, Texas A & M University (TAMU), and University of North Carolina Wilmington (UNCW). The workshop was held at the NOAA Center for Coastal Environmental Health & Biomolecular Research in Charleston, SC on 7-9 July 2009. The workshop convened to 1) address current practices among the groups conducting life history analysis, 2) decide on protocols to follow for the collaborative Prescott grant between VAQS and HSWRI, 3) demonstrate tissue preparation techniques and discuss shortcuts and pitfalls, 4) demonstrate data collection from prepared testes, ovaries, and teeth, and 5) discuss data analysis and prepare an outline and timeline for a future manuscript. The workshop concluded with discussions concerning the current collaborative Tursiops Life History Prescott grant award and the beginnings of a collaborative Prescott proposal with members of the Alliance of Marine Mammal Parks and Aquariums to further clarify reproductive analyses. This technical memorandum serves as a record of this workshop.

National Centers for Coastal Ocean Science (NCCOS) research highlights in the Chesapeake Bay

The Chesapeake Bay is the largest estuary in the United States. It is a unique and valuable national treasure because of its ecological, recreational, economic and cultural benefits. The problems facing the Bay are well known and extensively documented, and are largely related to human uses of the watershed and resources within the Bay. Over the past several decades as the origins of the Chesapeake’s problems became clear, citizens groups and Federal, State, and local governments have entered into agreements and worked together to restore the Bay’s productivity and ecological health. In May 2010, President Barack Obama signed Executive Order number 13508 that tasked a team of Federal agencies to develop a way forward in the protection and restoration of the Chesapeake watershed. Success of both State and Federal efforts will depend on having relevant, sound information regarding the ecology and function of the system as the basis of management and decision making. In response to the executive order, the National Oceanic and Atmospheric Administration’s National Centers for Coastal Ocean Science (NCCOS) has compiled an overview of its research in Chesapeake Bay watershed. NCCOS has a long history of Chesapeake Bay research, investigating the causes and consequences of changes throughout the watershed’s ecosystems. This document presents a cross section of research results that have advanced the understanding of the structure and function of the Chesapeake and enabled the accurate and timely prediction of events with the potential to impact both human communities and ecosystems. There are three main focus areas: changes in land use patterns in the watershed and the related impacts on contaminant and pathogen distribution and concentrations; nutrient inputs and algal bloom events; and habitat use and life history patterns of species in the watershed. Land use changes in the Chesapeake Bay watershed have dramatically changed how the system functions. A comparison of several subsystems within the Bay drainages has shown that water quality is directly related to land use and how the land use affects ecosystem health of the rivers and streams that enter the Chesapeake Bay. Across the Chesapeake as a whole, the rivers that drain developed areas, such as the Potomac and James rivers, tend to have much more highly contaminated sediments than does the mainstem of the Bay itself. In addition to what might be considered traditional contaminants, such as hydrocarbons, new contaminants are appearing in measurable amounts. At fourteen sites studied in the Bay, thirteen different pharmaceuticals were detected. The impact of pharmaceuticals on organisms and the people who eat them is still unknown. The effects of water borne infections on people and marine life are known, however, and the exposure to certain bacteria is a significant health risk. A model is now available that predicts the likelihood of occurrence of a strain of bacteria known as Vibrio vulnificus throughout Bay waters.

Growth, mortality, and hatchdate distributions of larval and juvenile spotted seatrout (Cynoscion nebulosus) in Florida Bay, Everglades National Park

Life history aspects of larval and, mainly, juvenile spotted seatrout (Cynoscion nebulosus) were studied in Florida Bay, Everglades National Park, Florida. Collections were made in 1994−97, although the majority of juveniles were collected in 1995. The main objective was to obtain life history data to eventually develop a spatially explicit model and provide baseline data to understand how Everglades restoration plans (i.e. increased freshwater flows) could influence spotted seatrout vital rates. Growth of larvae and juveniles (<80 mm SL) was best described by the equation loge standard length = –1.31 + 1.2162 (loge age). Growth in length of juveniles (12–80 mm SL) was best described by the equation standard length = –7.50 + 0.8417 (age). Growth in wet weight of juveniles (15–69 mm SL) was best described by the equation loge wet-weight = –4.44 + 0.0748 (age). There were no significant differences in juvenile growth in length of spotted seatrout in 1995 between three geographical subdivisions of Florida Bay: central, western, and waters adjacent to the Gulf of Mexico. We found a significant difference in wet-weight for one of six cohorts categorized by month of hatchdate in 1995, and a significant difference in length for another cohort. Juveniles (i.e. survivors) used to calculate weekly hatchdate distributions during 1995 had estimated spawning times that were cyclical and protracted, and there was no correlation between spawning and moon phase. Temperature influenced otolith increment widths during certain growth periods in 1995. There was no evidence of a relationship between otolith growth rate and temperature for the first 21 increments. For increments 22–60, otolith growth rates decreased with increasing age and the extent of the decrease depended strongly in a quadratic fashion on the temperature to which the fish was exposed. For temperatures at the lower and higher range, increment growth rates were highest. We suggest that this quadratic relationship might be influenced by an environmental factor other than temperature. There was insufficient information to obtain reliable inferences on the relationship of increment growth rate to salinity.

Larval abundance, distribution, and spawning habits of spotted seatrout (Cynoscion nebulosus) in Florida Bay, Everglades National Park, Florida

The spotted seatrout (Cynoscion nebulosus) is one of the most sought after recreational fish in Florida Bay, and it spends its entire life history within the bay (Rutherford et al.,1989b). The biology of adult spotted seatrout in Florida Bay is well known (Rutherford et al., 1982, 1989b) as is the distribution and abundance of juveniles within the bay. The habitats and diets of juveniles are well documented (Hettler, 1989; Chester and Thayer, 1990; Thayer et al., 1999; Florida Department of Environmental Protection1). Nevertheless, the spatial and temporal spawning habits of spotted seatrout and the distribution of larvae have only been partially described (Powell et al., 1989; Rutherford et al., 1989a).
