1. Setogenesis and characterization of the new moult substages in the freshwater shrimp Palaemon argentinus (Nobili, 1901) (Caridea: Palaemonidae)
Abstract The moult cycle of crustaceans is continuous and during different stages of this cycle, physiological, biochemical and morphological changes occur. Therefore, understanding the different stages of the moult cycle in the target species becomes critical for a wide range of biological studies. Here we describe the natural cycle changes in the freshwate

2. Influence of environmental variables on seasonal abundance and relative growth of Macrobrachium amazonicum (Crustacea: Decapoda: Caridea): variations of a continental population
RESUMO O objetivo do presente estudo foi avaliar a influência de fatores abióticos (condutividade, oxigênio dissolvido, pH, precipitação e temperatura da água) na abundância de Macrobrachium amazonicum (Heller, 1862), bem como comparar o crescimento relativo entre as categorias demográficas ao longo das estações do ano, em uma lagoa marginal locali

3. Richness and large-scale distribution of marine benthic caridean shrimps (Decapoda: Caridea) from the Eastern Tropical Pacific
Abstract Based on an updated checklist of the benthic caridean shrimp fauna of the Eastern Tropical Pacific (ETP), we analyzed their large-scale species richness distribution patterns using a grid approximation. Caridean fauna is composed of 183 species belonging to 67 genera and 18 families. Alpheidae, Palaemonidae and Thoridae contributed largely to specie

4. The influence of environmental variables in the reproductive performance of Macrobrachium amazonicum (Heller, 1862) (Caridea: Palaemonidae) females in a continental population
ABSTRACT Macrobrachium amazonicum is a commercially important freshwater prawn with a high degree of reproductive plasticity. The species is classified into two groups: coastal populations, with larger individuals exhibiting high fecundity and needing brackish water for larval development; and continental populations, with smaller specimens exhibiting low fe

5. Spatio-temporal variation of planktonic decapods along the leeward coast of the Fernando de Noronha archipelago, Brazil
Resumo Ambientes insulares tropicais são considerados verdadeiros hostspots devido a sua alta diversidade, endemismo e importância ecológica. Contudo, ainda são poucos os trabalhos que abordam a composição e ecologia de decápodes planctônicos nesses ambientes. Para determinar a composição, abundância e distribuição espaço-temporal dos decápode

6. Designation of a new genus Michaelimenes (Decapoda: Caridea: Palaemonidae), with new host record and range extension of its type species, M. perlucidus (Bruce, 1969)
Abstract A new palaemonid shrimp genus, Michaelimenes n. gen., is established for three Indo-West Pacific species, Periclimenes latipollex Kemp, 1922, Periclimenes perlucidus Bruce, 1969 (type species) and Periclimenes platydactylus Li, 2008. The present new genus can be immediately distinguished from other related genera by the combination of the second per

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. Reproductive strategy of the shrimp Nematopalaemon schmitti (Decapoda, Caridea, Palaemonoidea) on the southeastern coast of Brazil
Abstract The goal of this study was to evaluate the reproductive investment (RI) and the fecundity of the shrimp Nematopalaemon schmitti (Holthuis, 1950), caught by trawling in the southeastern Brazilian coast in 2008, 2009 and 2011. The carapace length (CL) of ovigerous females was measured and the development stage of their ovaries and embryos were analyze

9. New primers for amplification of cytochrome c oxidase subunit I barcode region designed for species of Decapoda (Crustacea)
Abstract We designed 14 new primers for amplification of the COI barcode region of decapod crustacean species. We tested, with high level of success, the generation of ~ 640 ± 49 base-pair sequences in selected groups of decapods (hermit crabs, squat lobsters, marine and freshwater crabs and shrimps), encompassing representatives of 27 genera of 15 families

10. Growth and reproductive biology of the amphidromous shrimp Palaemon pandaliformis (Decapoda: Caridea) in a Neotropical river from northeastern Brazil
ABSTRACT Population biology, growth and reproductive aspects of the amphidromous shrimp Palaemon pandaliformis (Stimpson, 1871) were investigated in a Neotropical river of northeastern Brazil. The specimens were collected every month from September 2009 to August 2010. Total and monthly sex ratios deviated in favour of males. Von Bertalanffy growth parameter

12. Snapping shrimps of the genus Alpheus (Caridea: Alpheidae) from Brazil: range extensions and filling distribution gaps
ABSTRACTThe objective of this study is to report new occurrences of five species of snapping shrimps of the genus AlpheusFabricius, 1798 in Brazil and, thus, contribute to the knowledge of their zoogeography. The southern limit of distribution of A. formosus Gibbes, 1850 and A. peasei (Armstrong, 1940) is extended from Paraná to Santa Catarina and from Bahi
