1. Life History Parameters of Genypterus brasiliensis (Teleostei: Ophidiidae), an Endemic Fisheries Resource of the Southwestern Atlantic
Abstract: Genypterus brasiliensis, a demersal fish of large size (1.3 m of total length), occurs in the southwest Atlantic (23 to 38oS) and well appreciated due to the quality of its flesh. It was analyzed through longline and trawl fisheries, and the average length and weight of 724 specimens were significantly different between them, with the biggest and h

2. External morphology, postcranial and appendicular osteology of three southwestern Atlantic flatfishes ( Paralichthys , Paralichthyidae), and comparisons with other congeneric species
ABSTRACT Comparisons of the external morphology and analysis of osteological features of the postcranial and appendicular skeletons of three southwestern Atlantic flatfish species of the genus Paralichthys (P. isosceles, P. orbignyanus and P. patagonicus) were carried out. Bones are described, and detailed morphological, morphometric and meristic characteris

3. The reproductive biology of Pinguipes brasilianus Cuvier, 1829 (Osteichthyes: Pinguipedidae) in temperate rocky reefs of Argentina
ABSTRACT Pinguipes brasilianus is a conspicuous and abundant rocky-reef fish inhabiting the Northern Patagonian gulfs of Argentina, Southwest Atlantic. This study describes its reproductive biology in this region. We made macroscopic and histological descriptions of the testis and ovary development, analyzed the evolution of the gonadosomatic index (GSI) in

4. The first occurrence of the Order Mormonilloida (Copepoda) in the Tropical Southwest Atlantic Ocean
Esta nota é o primeiro registro da ocorrência de Mormonilla phasma(Copepoda) no Sudoeste do Oceano Atlântico Tropical. Indivíduos fêmeas foram encontrados em águas superficiais na quebra da plataforma do estado do Rio Grande do Norte (Nordeste do Brasil) e entre 60 e 100 m de profundidade, na camada epipelágica ao largo do Arquipélago de São Pedro e

5. Reproductive biology of Cetengraulis edentulus (Cuvier, 1829), the major fishery resource in Guanabara Bay, Brazil
Cetengraulis edentulus is a broadely distributed engraulid in Southwest Atlantic, currently accounting for the main fish species commercially exploited at Guanabara Bay, Brazil. This study aimed to extend the knowledge on reproduction of C. edentulus at Guanabara Bay and to test whether some descriptors of reproductive activity, especially the gonadosomatic

6. Horizontal and vertical distribution of mesozooplankton species richness and composition down to 2,300 m in the southwest Atlantic Ocean
We describe the species richness, distribution and composition of mesozooplankton over the continental shelf and slope, and in the water masses in the Campos Basin, southwest Atlantic Ocean. We analyzed the mesozooplankton from two oceanographic cruises (rainy and dry seasons, 2009) with samples taken in five different water masses from the surface to 2,300

7. Projeções futuras do oceano Atlântico Sudoeste em dois cenários de aquecimento global / Future projections of the Southwest Atlantic in two global warming scenarios
O Atlântico Sudoeste comporta uma das regiões oceânicas mais energéticas do planeta: a Confluência Brasil-Malvinas (CBM). Essa região encerra o giro subtropical do Atlântico Sul e possui fundamental importância para a dinâmica desse oceano bem como para o clima regional. Através de saídas de modelos numéricos acoplados do 4°?elatório do IPCC, d

8. Rotas migratórias, áreas de uso intenso e padrões de mergulho de tartarugas-de couro (Dermochelys coriacea) no Atlântico Sul Ocidental / Migratory routes, high use areas and dive patterns of leatherback turtles (Dermochelys coriacea) in the Southwest Atlantic
As tartarugas marinhas são espécies ameaçadas, altamente migratórias que apresentam um ciclo de vida longo e uma ampla distribuição geográfica. Assim, melhorar a nossa compreensão sobre a ecologia espacial das tartarugas marinhas é essencial para a elucidação de aspectos da sua história de vida e para o desenvolvimento de medidas eficazes de cons

9. Distribution and reproductive biology of the Electric ray Discopyge tschudii Heckel, 1846 in San Matías Gulf, Northern Patagonia, Argentina
The Electric ray Discopyge tschudii is distributed in the Southwest Atlantic from southern Brazil to southern Argentina and in the Southeast Pacific from Peru to southern Chile. The main threat to this species is fishing. Discopyge tschudii is noncommercial and individuals caught are discarded on board. The present study analyzes the distribution and the mor

10. Bat flies on phyllostomid hosts in the Cerrado region: component community, prevalence and intensity of parasitism
Streblidae flies are specialised parasites of bat hosts, mainly phyllostomids. There is a high richness of streblids in the savannah-like Cerrado region; however, there is little quantitative data available in parasitological indices. Here, we describe the component community, prevalence and intensity of a streblid infestation on a phyllostomid bat assemblag

O conhecimento das preferências ecológicas de espécies de foraminíferos planctônicos tem sido muito utilizada em investigações paleoceanográficas obtendo bons resultados. O presente estudo realizou inferências sobre as condições oceanográficas das águas superficiais da porção sudoeste do Atlântico Sul nos últimos 450.000 anos através da var

12. Occurrence and distribution of larval lanternfish (Myctophidae) from the southwest Atlantic Ocean
This study analyzes the occurrence and distribution of lanternfish (Myctophidae) larvae along the Brazilian coast (12-22ºS) between 200 m and the surface. Three cruises were conducted during the spring/1998, winter/1999 and autumn/2000. A total of 3,394 lanternfish larvae were identified representing 27 species and Lepidophanes guentheri (Goode & Bean, 1896
