1. Distribution, diversity, and habitat partitioning of Scolecitrichidae species (Copepoda: Calanoida) down to 1,200 m in the Southwestern Atlantic Ocean
In this study, we analyzed the main distributional features of Scolecitrichidae species in the Southwestern Atlantic Ocean (northern region of Rio de Janeiro State) and determined and described their habitat partitioning, based on a night series of stratified samplings down to a depth of 1,200 m. A total of 18 species from seven genera were identified and gr

2. Distribuição e abundância de larvas de Phosichtyidae e condições oceanográficas na região entre o cabo de São Tomé (RJ) e a ilha de São Sebastião (SP) / Distribution and abundance of larval Phosichthyidae and oceanographic conditions in the region between São Tomé cape (RJ) and São Sebastião island (SP)
A distribuição horizontal e vertical das larvas de peixes mesopelágicos de Phosichthyidae foi descrita a partir de dados amostrados desde a superfície até 200 m de profundidade, e em 5 estratos na coluna de água. As coletas foram realizadas no verão e inverno de 2002, em radiais perpendiculares à costa Sudeste do Brasil, entre o cabo de São Tomé (R

3. Population structure, growth and reproduction of Maurolicus stehmanni Parin &Kobyliansky, 1993 (Teleostei: Sternoptychidae) in south-eastern and south Brazilian economic exclusive zone. / Estrutura da população, crescimento e reprodução de Maurolicus stehmanni Parin &Kobylianski, 1993 (Teleostei: Sternoptychidae) na zona econômica e exclusiva do sul e sudeste do Brasil.
Maurolicus é um gênero representado por peixes mesopelágicos, com elevada biomassa na Zona Econômica Exclusiva sudeste sul brasileira. O material deste estudo provém de arrastos com rede de meia água efetuados com o N/Oc. Atlântico Sul, entre as isóbatas de 100 e 1500 m e entre as latitudes 22° e 35° S, realizados no inverno de 1996; outono de 1997

4. CO Dehydrogenase Genes Found in Metagenomic Fosmid Clones from the Deep Mediterranean Sea▿ †
The use of carbon monoxide (CO) as a biological energy source is widespread in microbes. In recent years, the role of CO oxidation in superficial ocean waters has been shown to be an important energy supplement for heterotrophs (carboxydovores). The key enzyme CO dehydrogenase was found in both isolates and metagenomes from the ocean's photic zone, where CO

5. Prevalence of the Chloroflexi-Related SAR202 Bacterioplankton Cluster throughout the Mesopelagic Zone and Deep Ocean†
Since their initial discovery in samples from the north Atlantic Ocean, 16S rRNA genes related to the environmental gene clone cluster known as SAR202 have been recovered from pelagic freshwater, marine sediment, soil, and deep subsurface terrestrial environments. Together, these clones form a major, monophyletic subgroup of the phylum Chloroflexi. While mem

6. Measurement of Microbial Activity and Growth in the Ocean by Rates of Stable Ribonucleic Acid Synthesis
A relatively simple and extremely sensitive technique for measuring rates of stable ribonucleic acid (RNA) synthesis was devised and applied to bacterial cultures and seawater samples. The procedure is based upon the uptake and incorporation of exogenous radiolabeled adenine into cellular RNA. To calculate absolute rates of synthesis, measurements of the spe
