1. PADRONIZAÇÃO DA QUANTIFICAÇÃO DE GLUTATIONA REDUTASE EM Aegla singularis (ANOMURA, CRUSTACEA) UTILIZANDO PLANEJAMENTO EXPERIMENTAL DCCR
Glutathione Reductase (GR) plays a key role in the maintenance of GSH homeostasis, variations in its activity may indicate damage from environmental contaminants. Experimental planning is a strategy to reduces time and cost in enzymatic assays. In this work, DCCR experimental planning was used to standardize and to validate the measure of GR in Aegla singula

2. On the identity of Porcellana paivacarvalhoi Rodrigues da Costa, 1968 (Crustacea: Anomura: Porcellanidae)
Abstract Porcellana paivacarvalhoi Rodrigues da Costa, 1968, described from southeastern Brazil (São Sebastião, São Paulo), is morphologically similar to the eastern Atlantic P. platycheles (Pennant, 1777), and also to the west African P. africana Chace, 1956. The synonymy between P. paivacarvalhoi and P. platycheles was proposed by previous authors witho

3. 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

4. Intraspecific variation in megalopae of Clibanarius antillensis (Anomura, Diogenidae) among western Atlantic populations
ABSTRACT The objective of this study was to describe the morphology of Clibanarius antillensis Stimpson, 1859 megalopae collected in the vicinity of Isla Sacrificios, Mexico, and compare it to previous descriptions originated from Brazilian and Panamanian specimens raised in laboratory conditions. We found four meristic differences between the Brazilian and

5. Population size of Aegla longirostri Bond-Buckup and Buckup, 1994 (Crustacea, Decapoda, Anomura): comparison of methods with the mark-recapture technique in closed population
Abstract The aim of this study is to estimate the population size of Aegla longirostri Bond-Buckup and Buckup, 1994 in a subtropical low-order stream using the mark-recapture technique. We also tested if the Bayesian model is a promising estimator of population size. Data were collected in two periods, in spring 2010 (seven-day sampling) and in fall 2011(fiv

6. Nova espécie de Temnocephala (Platyhelminthes, Temnocephalida) ectosimbionte sobre espécies vulneráveis de eglídeos (Crustacea, Anomura) da Região Neotropical
Resumo: Uma nova espécie do gênero Temnocephala Blanchard, 1849 da região sul do Brasil foi encontrada sobre duas espécies de crustáceos anomuros, Aegla spinipalma Bond-Buckup & Buckup, 1994 e Aegla grisella Bond-Buckup & Buckup, 1994, a última classificada como uma espécie vulnerável pela Lista de Referência da Fauna Ameaçada de Extinção no Rio

7. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

8. Asynchronous Hatching and Extended Parental Care in Aegla schmitti (Decapoda, Anomura)
ABSTRACT The aim of this study was to describe the behavior of newly-hatched juveniles and maternal care in Aegla schmitti. The experiment was conducted using seven ovigerous females with eggs at different stages of embryonic development and 12 eggs that had been placed in a separate aquarium. We observed asynchronous hatching in all females, with a mean of

9. New records of intersexuality in porcelain crabs (Crustacea: Decapoda: Anomura: Porcellanidae)
Abstract The occurrence of intersex specimens of Lissoporcellana quadrilobata (Miers, 1884), Pisidia bluteli (Risso, 1816) and Pisidia longimana (Risso, 1816) is recorded for the first time and their secondary sexual characters analyzed. Intersex specimens were collected in regions regularly affected by pollution. There is a high possibility that intersexual

11. Shell occupation by the land hermit crab Coenobita violascens (Anomura, Coenobitidae) from Phuket Island, Thailand
Abstract Shell occupation by the land hermit crab Coenobita violascens Heller, 1862 was investigated from January 2011 to March 2012 on Phuket Island in the Andaman Coast of Thailand. The samples of C. violascens were collected monthly using multiple quadrat sampling. Twenty shell species from 11 families were found occupying by C. violascens, which were mai

12. Checklist of fossil decapod crustaceans from tropical America. Part I: Anomura and Brachyura
Abstract Our knowledge of fossil crustaceans from the tropics has increased considerably during recent decades, thanks to novel findings and the re-examination of museum specimens. However, several previous records have been misidentified, numerous museum specimens have never been reported, and many new discoveries are yet to be published. Here, we present a
