1. A compilation of longevity data in decapod crustaceans
Abstract Longevity information was collected from 219 literature sources for 244 decapod crustaceans, representing 1.7% of species, 4.8% of genera and 30% of families. Reliable methods of age determination (laboratory rearing, mark-recapture method, growth models, lipofuscin method) revealed longevities from 0.1 to 72 years, corresponding to a 700-fold diffe

2. A retrospective analysis of scientific publications on the deep sea from 1987 to 2016
Abstract: The deep sea remains the least known biome. Despite this fact, anthropic activities have affected these regions in various ways. The objective of this study was to outline the scientific production scenario based on deep sea research and to analyze trends present in the literature. For this, the bibliographical resources available from the Web of S

3. Wet Days in the Dry Quarter of the Alcântara Launch Center Region: Observational Features
ABSTRACT: Precipitation events are infrequent in the dry quarter (SON) of the Alcântara Launch Center (Centro de Lançamento de Alcântara, CLA), the main launch site of the Brazilian Space Program. However, their occurrence could be a risk for activities during launch missions. In this work, the observational features of wet days (daily precipitation total

4. Reproductive biology of the Brazilian blind electric ray Benthobatis kreffti (Chondrichthyes: Narcinidae)
RESUMO Este estudo apresenta informações sobre a biologia reprodutiva da raia elétrica cega brasileira Benthobatis kreffti, endêmica do sul e sudeste brasileiros. Os indivíduos foram capturados com arrasto de fundo, em 2003 e 2007, a 492-501 m de profundidade no talude continental do Estado de São Paulo. Um total de 152 fêmeas (115-299 mm) e 144 macho

5. Influencia de la temperatura en ensayos de arrancamiento sobre diferentes sistemas epoxi-acero de uso en conectores de ductos flexibles
ABSTRACT In the offshore oil fields located in deep and ultra-deep waters they are used flexible pipes. In many cases inside these pipes, the hydrocarbons are transported at elevated temperatures. At the ends of the flexible pipes are installed end fittings, these are the connection with sea platforms and different subsea systems. In the assembly of end fitt

6. First report of deep-sea copepod Megacalanus princeps Wolfenden, 1904 (Calanoidea: Megacalanidae) from southwestern Atlantic
Abstract The deep-sea copepod Megacalanus princeps Wolfenden, 1904 was previously recorded from the northern and southeastern Atlantic, Indian and Pacific oceans, but not previously observed from southwestern Atlantic. Here we report its first occurrence in Brazilian waters. The current record increases the knowledge on the species distribution and on the de

7. New records and bathymetric distribution of deep-sea shrimps of the family Glyphocrangonidae (Decapoda: Caridea) from the Potiguar Basin, northeastern Brazil
Abstract The caridean family Glyphocrangonidae Smith, 1884 is monotypic, including only the genus Glyphocrangon A. Milne-Edwards, 1881. The species of this genus are exclusively inhabitants of deep sea. The current contribution aims to enrich the knowledge of Glyphocrangon in the southwestern Atlantic, by reporting its occurrence and bathymetric distribution

8. Draft genome sequence of sulfur-reducing archaeon Thermococcus thioreducens DSM 14981T
Abstract Thermococcus thioreducens DSM 14981T, a sulfur-reducing archaeon, was isolated from the rainbow hydrothermal vent site on the Mid-Atlantic Ridge. Herein, we report the draft genome sequence of T. thioreducens DSM 14981T; we obtained 41 contigs with a genome size of 2,052,483 bp and G + C content of 53.5%. This genome sequence will not only help unde

9. Primitive decapods from the deep sea: first record of blind lobsters (Crustacea: Decapoda: Polychelidae) in northeastern Brazil
ABSTRACT We report herein the occurrence of the infraorder Polychelida in Potiguar Basin, northeastern Brazil. Specimens were collected by the project "Avaliação da Biota Bentônica e Planctônica na porção offshore das Bacias Potiguar e Ceará", developed by the Brazilian Oil Company (PETROBRAS). Three species were recorded for the first time in this re

10. Pressure tolerance of tadpole larvae of the Atlantic ascidian Polyandrocarpa zorritensis: potential for deep-sea invasion
Resumo Dentre as teorias mais aceitas de como surgiu a fauna de oceano profundo está a de que organismos de águas rasas migraram para águas mais profundas e lá especiaram até originarem as comunidades de mar profundo atuais. No entanto, muitos organismos são impedidos de fazer longas migrações verticais por conta do aumento da pressão hidrostática.

11. A new deep-sea species of Barathronus Goode & Bean from Brazil, with notes on Barathronus bicolor Goode & Bean (Ophidiiformes: Aphyonidae)
Uma nova espécie de Barathronus (Ophidiiformes: Aphyonidae) é descrita a partir de um único exemplar macho (101 mm CP) coletado com arrasto de fundo no talude continental do Rio Grande do Norte, nordeste do Brasil, entre 1.964 e 2.045 m de profundidade. A espécie nova é diagnosticada entre as congêneres pela seguinte combinação de caracteres: peritô

12. La pesca comercial y el estudio de la fauna marina en la Argentina, 1890-1930
This paper examines the relationship between the development of commercial maritime fishing and the study of marine fauna in Argentina between the end of the nineteenth century and the first decades of the twentieth century. It analyzes ichthyological research, the commercialization of fresh maritime products and the opportunities that urban markets offered
