Linefish resources annual report for the year 2000. Part 2: species profile

This work refers to the same biological aspects of Chrysoblephus puniceus (marreco), Polysteganus coeruleopunctatus (cachucho) and Cheimerus nufar (robalo). It shows the progress in the biological study of the three species, pointing out at the same time the few discrepancies, which still need to be resolved.

Changes in body composition and fatty acid profile during embryogenesis of quillback rockfish (Sebastes maliger)

We investigated developmental changes in the body compositions and fatty acid (FA) profiles of embryos and preparturition larvae of the quillback rockfish (Sebastes maliger). Comparisons of proximate composition data from early-stage embryos with data from hatched preparturition larvae taken from wild-caught gravid females indicated that embryos gain over one-third their weight in moisture while consuming 20% of their dry tissue mass for energy as they develop into larvae. Lipid contributed 60% of the energy consumed and was depleted more rapidly than protein, indicating a protein-sparing effect. Oil globule volume was strongly correlated with lipid levels, affirming its utility as an indicator of energetic status. FA profiles of early embryos differed significantly from those of hatched larvae. Differences in the relative abundances of FAs between early embryos and hatched larvae indicated different FA depletion rates during embryonic development. We conclude that some metabolically important FAs may prove useful in assessing the condition of embryos and preparturition larvae, particularly 20:4n-6, which cannot be synthesized by many marine fish and which is conserved during embryogenesis. Variability in body composition and energy use among rockfish species should be considered when interpreting any measures of condition.

The ecology of Atlantic white cedar wetlands: a community profile

This monograph on the ecology of Atlantic white cedar wetlands is one of a series of U.S. Fish and Wildlife Service profiles of important freshwater wetland ecosystems of the United States. The purpose of the profile is to describe the extent, components, functioning, history, and treatment of these wetlands. It is intended to provide a useful reference to relevant scientific information and a synthesis of the available literature. The world range of Atlantic white cedar (Chamaecyparis thyoides) is limited to a ribbon of freshwater wetlands within 200 km of the Atlantic and Gulf coasts of the United States, extending from mid-Maine to mid-Florida and Mississippi. Often in inaccessible sites and difficult to traverse, cedar wetlands contain distinctive suites of plant species. Highly valued as commercial timber since the early days of European colonization of the continent, the cedar and its habitat are rapidly disappearing. This profile describes the Atlantic white cedar and the bogs and swamps it dominates or codominates throughout its range, discussing interrelationships with other habitats, putative origins and migration patterns, substrate biogeochemistry, associated plant and animal species (with attention to those that are rare, endangered, or threatened regionally or nationally), and impacts of both natural and anthropogenic disturbance. Research needs for each area are outlined. Chapters are devoted to the practices and problems of harvest and management, and to an examination of a large preserve recently acquired by the USFWS, the Alligator River National Wildlife Refuge in North Carolina.

FishBase species profile: Clarias gariepinus (Burchell, 1822) North African catfish

In this issue NAGA introduces a new page on profiles of fish species. This page will be a permanent feature of the NAGA and will be based on information derived from FishBase (http://www.fishbase.org), the world’s premier information system on fishes and a global public good. FishBase is being developed by the WorldFish Center and an International Consortium. The first species selected is the North African catfish Clarias gariepinus, one of the most important freshwater fish species in Africa. It has been chosen in honor of Prof Dr Guy Teugels of the Musée Royal de l’Afrique Centrale (MRAC) of Tervuren, Belgium, who recently passed away and who spent many years investigating this species.

"Heroes" and "Villains" of World History across Cultures

Emergent properties of global political culture were examined using data from the World History Survey (WHS) involving 6,902 university students in 37 countries evaluating 40 figures from world history. Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.

A Demographic Profile of Participants in Two Gulf of Mexico Inshore Shrimp Fisheries and Their Response to the Texas Closure

A social study of the shrimp fisheries of Galveston Bay, Tex., and Calcasieu Lake, La., was made during the summer of 1987 to examine the impacts of the seasonal closure of the Federal waters off Texas and to understand the infrastructure and demographic processes of these two diverse fisheries. Survey instruments were administered to 159 shrimp boat captains: 89 from Galveston Bay and 70 from Calcasieu Lake. Shrimp-house owners were interviewed in each region as well. The results suggest that the inshore fisheries (i.e., shrimpers and shrimp houses) are distinct from the offshore fisheries. The infrastructure of the two inshore fisheries examined differ in that the market distribution of shrimp from Galveston Bay was more diffuse than from Calcasieu Lake. Much more of the shrimp harvested from Galveston Bay was channelled into the surrounding community than from Calcasieu Lake. The distribution of age,years as a commercial fisherman, and family involvement in fishing suggest that participation in Calcasieu Lake's and Galveston Bay's inshore fisheries have expanded concurrent with declining economies. While overall the Texas closure had little impact on either of the inshore fisheries, the Galveston Bay shrimpers experienced more of a direct impact on their livelihood than Calcasieu Lake shrimpers.

A tutela extrapatrimonial do nascituro no ordenamento jurídico brasileiro

Propõe-se estudo teórico com o objetivo de examinar a extensão e os limites da proteção jurídica concedida aos nascituros no ordenamento jurídico brasileiro. Há décadas a doutrina nacional se debruça acerca da exegese mais adequada do art. 4 do Código Civil de 1916, que, atualmente, corresponde ao art. 2 do Código Civil, com pequenas modificações textuais, mas sem alterar substancialmente o dispositivo. O Código Civil aparentemente optou pela atribuição da personalidade civil somente após o nascimento com vida, assegurando, contudo, os direitos do nascituro desde a concepção. O próprio Código Civil prevê expressamente direitos ao nascituro, como o direito a se beneficiar de doação e herança, o direito ao reconhecimento de paternidade e o direito à curatela. Nas últimas décadas outras leis infraconstitucionais reforçaram a proteção do nascituro, para resguardar direitos próprios do nascituro, entre eles o direito à assistência pré-natal, o direito à saúde e à integridade física e o direito aos alimentos. Não obstante, é costumeira a consciência de que o reconhecimento desses direitos pressupõe a concessão da personalidade civil desde a concepção, visto que a titularidade deles dependeria do gozo pleno da personalidade. Embora, pelo perfil do interesse, não haja óbice ao reconhecimento de situações patrimoniais, existenciais e dúplices, que podem ser titularizadas pelo nascituro, a preocupação do legislador nacional sempre se centrou nos aspectos patrimoniais. Diante da existência de situações jurídicas subjetivas merecedoras de proteção por parte do ordenamento jurídico titularizáveis pelos nascituros, pretende-se identificar e revelar os direitos extrapatrimoniais do ente por nascer como merecedores de tutela no direito brasileiro. Mediante pesquisa bibliográfica, observada a metodologia do direito civil constitucional, serão examinados os conceitos de nascituro, bem como as teorias existentes sobre os direitos que lhe são assegurados, com vista à possibilidade de proteção de seus direitos existenciais
