1. Population dynamics of the mud crab Panopeus austrobesus Williams, 1983 (Brachyura: Panopeidae) associated with a mussel farm at the southeastern Brazilian coast
Abstract Mussel farms are one of the most important modalities of aquaculture and constitute almost 80% of the total bivalve production in Brazil, representing about 5% of the national production. Brachyuran crabs are common inhabitants of these environments and represent an important link in coastal marine food chains. The aim of this investigation is to de

2. Occurrence of potentially pathogenic Vibrio in oysters (Crassostrea gigas) and waters from bivalve mollusk cultivations in the South Bay of Santa Catarina
Introduction This research aimed to identify and quantify potentially pathogenic Vibrio from different cultivations of bivalve shellfish in the State of Santa Catarina, Brazil, and water regions in the South Bay, as well as correlate the incidence of these microorganisms with the physicochemical parameters of marine waters. Methods Between October 2008 an

3. Marcadores orgânicos moleculares como ferramentas no monitoramento ambiental: Avaliação da distribuição de Alquilbenzeno Lineares (LABs) em organismos e sedimentos, como indicativo de exposição ao esgoto em áreas costeiras / Organic molecular markers as tools in environmental monitoring: Evaluation of Linear Alkylbenzene (LABs) distribution in organisms and sediments, as indicative of exposure to sewage in coastal areas
The sewage disposal in coastal areas can cause impacts to marine life, altering the balance of the ecosystem and biodiversity and causing serious diseases in humans. In this study, the concentration of a set of molecular markers for the introduction of organic sewage into the marine environment: linear alkylbenzene (LAB), in samples of sediment, oysters (Cra

4. Archaeozoology of marine mollusks from Sambaqui da Tarioba, Rio das Ostras, Rio de Janeiro, Brazil
A reference inventory of prehistoric marine mollusks from the Rio das Ostras region was created based on an excavation carried out at the Sambaqui da Tarioba shellmound. Patterns of richness and biogeography were studied, and the representativeness of bivalve and gastropod diversities found at this archaeological site were inferred. A total of 47 taxa belong

5. Paleontologia da Bacia do Araripe, nordeste do Brasil: histÃrico, evidÃncias marinhas e uma nova espÃcie de BivÃlvio
This study presents the evolution of paleontological knowledge and date evidence to date on marine paleoenvironments in the Araripe Basin, northeastern Brazil. It is also description and analysis of isotopes of C and O of a new species of bivalve mollusk as a contribution on knowledge of mollusk fauna and paleoenvironment of the Santana Formation (Early Cret

6. Analise ultra-estrutural de espermatozoides de especies de bivalves marinhos / Spermatozoan ultrastructural analyses of marine bivalve species
Aplicações de Microscopias Eletrônicas de Transmissão (TEM) e Varredura (SEM) têm contribuído para a sistemática de moluscos bivalves e classificações de táxons mais abrangentes. Em muitos casos, os resultados dessas ferramentas metodológicas têm notavelmente complementado os estudos comparativos da anatomia interna e dos caracteres conquiliológ

7. Avaliação da contaminação de ostras (Crassostrea rhizophorae) por especies de Cryptosporidium e Giardia em um ambiente de estuario do litoral de São Paulo / Evaluation of the contamination of oysters (Crassostrea rhizophorae) by species of Cryptosporidium and Giardia in a estuarine environment from São Paulo coast
Bivalve molluscs are great filter feeders that may accumulate and concentrate substances, particles and even pathogens in their tissues, if the places that they inhabit or are cultivated receive contaminated effluents dispose. These animals, which serve as biological indicators of faecal contamination, may transmit the protozoa accumulated in their tissues,

8. Taxonomy of invertebrate fossils (Oligocene-Miocene) from the King George island (West Antarctica) and paleobiogeography of cenozoic Bivalvia from Antarctica / Taxonomia de invertebrados fósseis (Oligoceno-Mioceno) da ilha Rei George (Antártica ocidental) e paleobiogeografia dos Bivalvia cenozóicos da Antártica
The research presented in this dissertation comprised part of the CNPq - PROANTAR Project 550352/02-3 "Mudanças paleoclimáticas na Antártica durante o Cenozóico: o registro geológico terrestre", which studies Cenozoic deposits from King George Island in order to elucidate the environmental and climatic Cenozoic histories of this Antarctic region.

9. EFEITOS DO PETRÓLEO SOBRE A ASSOCIAÇÃO DE MACROINVERTEBRADOS BENTÔNICOS DE PRAIAS ARENOSAS DO EXTREMO SUL DO BRASIL.
The benthic marine organisms in the sand beach intertidal zone have a great ecological complexity, being a major trophic link among the phytoplankton, organic detritus and the higher trophic levels. Any anthropogenic disturbance that affects these organisms, such as an oil spill can cause changes in all trophic levels of coastal communities. Due to their sed

12. Avaliação de variações bioquímicas em moluscos bivalves em resposta ao estresse ambiental / Evaluation of biochemical variations in bivalve molluscs in response to environmental stress
In this work, some biochemical systems were evaluated in different tissues of bivalve mollusks, in response to different stress, in order to verify the possibility of use of these systems as pollution bioindicators in marine environmental monitoring studies, as well as to verify the influence of environmental variations not related to pollution on these syst
