Population structure, long-term connectivity, and effective size of mutton snapper (Lutjanus analis) in the Caribbean Sea and Florida Keys

Genetic structure and average long-term connectivity and effective size of mutton snapper (Lutjanus analis) sampled from offshore localities in the U.S. Caribbean and the Florida Keys were assessed by using nuclear-encoded microsatellites and a fragment of mitochondrial DNA. No significant differences in allele, genotype (microsatellites), or haplotype (mtDNA) distributions were detected; tests of selective neutrality (mtDNA) were nonsignificant after Bonferroni correction. Heuristic estimates of average long-term rate of migration (proportion of migrant individuals/generation) between geographically adjacent localities varied from 0.0033 to 0.0054, indicating that local subpopulations could respond independently of environmental perturbations. Estimates of average longterm effective population sizes varied from 341 to 1066 and differed significantly among several of the localities. These results indicate that over time larval drift and interregional adult movement may not be sufficient to maintain population sustainability across the region and that there may be different demographic stocks at some of the localities studied. The estimate of long-term effective population size at the locality offshore of St. Croix was below the minimum threshold size considered necessary to maintain the equilibrium between the loss of adaptive genetic variance from genetic drift and its replacement by mutation. Genetic variability in mutton snapper likely is maintained at the intraregional level by aggregate spawning and random mating of local populations. This feature is perhaps ironic in that aggregate spawning also renders mutton snapper especially vulnerable to overexploitation.

Assessment of habitat quality for juvenile California halibut (Paralichthys californicus) in a seasonally arid estuary

We evaluated habitat quality for juvenile California halibut (Paralichthys californicus) in a Pacific Coast estuary lacking in strong salinity gradients by examining density, recent otolith growth rates, and gut fullness levels of wild-caught and caged juveniles for one year. Juveniles <200 mm standard length were caught consistently in the inner, central, and outer sections of the estuary. The density of juveniles was two times higher in the inner estuary during most of the year, consistent with active habitat selection by part of the population. A generalized linear model indicated temperature, sampling time, and the interaction between salinity and temperature were significantly related to density. However, the model explained only 21% of the variance. Gut fullness levels of wild-caught juveniles were highest during the summer, but recent otolith growth rates were not related to temperature. The proportion of individuals feeding successfully indicated that seasonal differences in food availability are more important than spatial variation in prey abundance in driving feeding success. Feeding success of caged fishes was limited, precluding the use of growth rates as indicators of local habitat quality. However, marginal increment widths were reliable indicators of somatic growth at low growth rates over two-week periods. The relatively high growth rates and abundance of small wild-caught juveniles found throughout the estuary indicates that the entire estuary system has the potential for serving as nursery habitat.

Effects of commercial fishing on local abundance of Pacific cod (Gadus macrocephalus) in the Bering Sea

Groundfish fisheries in the southeast Bering Sea in Alaska have been constrained in recent years by management measures to protect the endangered Steller sea lion (Eumetopias jubatus). There is concern that the present commercial harvest may produce a localized depletion of groundfish that would affect the foraging success of Steller sea lions or other predators. A three-year field experiment was conducted to determine whether an intensive trawl fishery in the southeast Bering Sea created a localized depletion in the abundance of Pacific cod (Gadus macrocephalus). This experiment produced strongly negative results; no difference was found in the rate of seasonal change in Pacific cod abundance between stations within a regulatory no-trawl zone and stations in an immediately adjacent trawled area. Corollary studies showed that Pacific cod in the study area were highly mobile and indicated that the geographic scale of Pacific cod movement was larger than the spatial scale used as the basis for current no-trawl zones. The idea of localized depletion is strongly dependent on assumed spatial and temporal scales and contains an implicit assumption that there is a closed local population. The scale of movement of target organisms is critical in determining regional effects of fishery removals.

A judicialização da saúde na perspectiva da gestão local : um estudo da experiência de Saquarema - RJ

A Constituição Federal de 1988 garante o direito à saúde no Brasil a todos os brasileiros. Para assegurar esse direito constitucional foi instituído através das Leis ns 8080/90 e 8142/90, o Sistema Único de Saúde (SUS), organização de direito público que normatiza toda a prestação de assistência à saúde da população. O SUS, constituído a partir de diretrizes filosóficas, garante assistência universal e gratuita em todas as áreas do setor saúde. Incorporado ao SUS através da Política Nacional de Medicamentos e depois pela Política Nacional de Assistência Farmacêutica, o acesso a medicamentos é um setor estratégico da política pública de saúde. A judicialização do acesso à saúde e à assistência farmacêutica, que se converteu em recurso necessário para garantir o direito à saúde no Brasil, é hoje um importante componente da gestão municipal de saúde. Trata-se de um processo que se inicia com a aquisição de medicamentos para tratar o HIV/Aids na década de 1990. Este trabalho realizou uma pesquisa, de caráter exploratório, no município de Saquarema, que permitiu construir uma análise (qualitativa e quantitativa) das ordens judiciais, procedentes da Defensoria Pública da Comarca de Saquarema para aquisição de medicamentos, entre 01/01/2011 e 31/12/2012, totalizando 106 demandas, a partir de prescrições médicas individuais feitas por profissionais do SUS. A pesquisa constatou que a hipossuficiência de recursos e a urgência dos autores das ações são os principais respaldos das decisões judiciais. Ela também observou que a maioria dos requerentes é do gênero feminino, com idade acima de 61 anos, com patologias crônicas e fazendo uso contínuo de medicamentos. Esses medicamentos foram prescritos por quatro profissionais médicos oriundos de quatro especialidades (oftalmologia, cardiologia, endocrinologia e pediatria) e representam 60% das demandas judiciais. A situação de conflito pesquisada mostra que o direito à saúde está sendo exercido através do Poder Judiciário, com uma Defensoria Pública relativamente eficiente, atendendo a uma população com poucos recursos econômicos, que faz uso de medicamentos para tratamento de doenças crônicas e degenerativas. A prescrição médica individual é o documento necessário para requisitar os medicamentos de uso contínuo. A pesquisa, após analisar os principais resultados, aponta algumas alternativas, chamadas de ações defensivas, que as gestões municipais de saúde em Saquarema e outras municipalidades podem adotar.

Population structure and variance effective size of red snapper (Lutjanus campechanus) in the northern Gulf of Mexico*

We assayed allelic variation at 19 nuclear-encoded microsatellites among 1622 Gulf red snapper (Lutjanus campechanus) sampled from the 1995 and 1997 cohorts at each of three offshore localities in the northern Gulf of Mexico (Gulf). Localities represented western, central, and eastern subregions within the northern Gulf. Number of alleles per microsatellite per sample ranged from four to 23, and gene diversity ranged from 0.170 to 0.917. Tests of conformity to Hardy-Weinberg equilibrium expectations and of genotypic equilibrium between pairs of micro-satellites were generally nonsignificant following Bonferroni correction. Significant genic or genotypic heterogeneity (or both) among samples was detected at four microsatellites and over all microsatellites. Levels of divergence among samples were low (FST ≤0.001). Pairwise exact tests revealed that six of seven “significant” comparisons involved temporal rather than spatial heterogeneity. Contemporaneous or variance effective size (NeV) was estimated from the temporal variance in allele frequencies by using a maximum-likelihood method. Estimates of NeV ranged between 1098 and >75,000 and differed significantly among localities; the NeV estimate for the sample from the northcentral Gulf was >60 times as large as the estimates for the other two localities. The differences in variance effective size could ref lect differences in number of individuals successfully reproducing, differences in patterns and intensity of immigration, or both, and are consistent with the hypothesis, supported by life-history data, that different “demographic stocks” of red snapper are found in the northern Gulf. Estimates of NeV for red snapper in the northern Gulf were at least three orders of magnitude lower than current estimates of census size (N). The ratio of effective to census size (Ne/N) is far below that expected in an ideal population and may reflect high variance in individual reproductive success, high temporal and spatial variance in productivity among subregions or a combination of the two.

Collaborative training program in coastal management in the Philippines: a local initiative with a global perspective

A collaborative project in developing a broad-based coastal management training program in the Philippines is being undertaken by a group of government and nongovernment agencies. It addresses the lack of expertise in planning an implementation for coastal management in the country. The process will be documented to serve as a guide in starting and maintaining the process of collaborative training in coastal management in the region. Other training initiatives are outlined including regional and global efforts.

Local solutions to challenges of West Indian Ocean fisheries development

The West Indian Ocean is rich in biodiversity and marine resources. This paper gives an overview of fisheries development and resource management in the region. There are many shared issues that must be addressed within countries and at the regional level. These are illustrated by examples from three countries. In Mozambique the issues of lack of information about artisanal fisheries, excessive harvesting of juveniles and conflicts between artisanal and commercial sectors are highlighted. Elements in addressing this include targeted research and decision-making support tools. The challenges faced in Somalia stem primarily from the political instability that contributed to an absence of sound fisheries policy. An example of a highly participatory process to develop the policy provides a model for other countries. In Tanzania, the issue of dynamite fishing was addressed by local communities initiating a program to promote wise use of the resources. There is a clear opportunity for better collaboration and greater integration of fisheries research and management on a regional basis. There is also much to be learnt by the sharing of experiences between countries. This has been initiated by some recently launched regional cooperation projects, but there are still many challenges facing this region.

Poder local, cidadania e participação popular no município de Maricá: uma análise crítica das regras do jogo

O tema que nos propomos a estudar é o Poder local, cidadania e participação popular no município de Maricá. A delimitação espaço temporal de nosso projeto situa-se na cidade de Maricá, localizada na Sub-região dos Lagos, no Estado do Rio de Janeiro, a partir do ano de 2009, tendo como pano de fundo as especificidades da formação social brasileira e as determinações estruturais resultantes da mundialização do capital. É importante ressaltar que o termo participação popular pertinente a este estudo refere-se à criação ou ampliação de canais institucionais para intervenção da população no controle social ou na construção do debate orçamentário nas cidades, que exigem estratégias políticas que são absolutamente fundamentais para a construção de uma nova sociedade pautada em princípios radicalmente democráticos.As contradições e as possibilidades da luta pelo direito à cidade, frente à ampliação mercantilização do espaço e a tradição clientelista na cidade de Maricá, foram os desafios que procuraremos responder nesta tese. Para tal, elencamos as seguintes hipóteses: 1) a disputa de projetos societários, a partir da luta de classes, pode ser identificada nas cidades através das propostas antagônicas de cidade-mercadoria e do direito à cidade, contradições estas que se reproduzem inclusive em governos municipais comprometidos com a ampliação dos canais de participação popular; 2) a gestão participativa municipal pode tanto contribuir para a subjetivação das classes subalternas no sentido das mesmas intervirem e até modificarem a esfera pública, quanto se tornar um espaço instrumental ao clientelismo e/ou associativismo local; 3) para evitar tal distorção é importante que agentes contestatórios da sociedade civil retomem o tensionamento de canais institucionais de participação popular nas cidades, enquanto estratégia de ampliação da esfera pública, visto que tais espaços têm sido ocupados por agentes muito mais colaborativos que conflituosos, despolitizando possibilidades, tais como: o orçamento participativo, audiências públicas e os Conselhos Municipais; 4) as cidades do CONLESTE, em especial o município de Maricá, tornaram-se foco do interesse da burguesia nacional e internacional, após as discussões em torno do COMPERJ e do Pré-sal, dificultando e/ou inviabilizado um direcionamento autônomo do poder local em torno das propostas engendradas pela participação popular na cidade, contexto que torna o urgente o tensionamento visando à possibilidade de garantia da função social da cidade, conforme preconiza a Carta Mundial de Direito à Cidade, em especial frente à especulação imobiliária.
