“…Devido a esta heterogeneidade de hábitats e nichos, há uma variedade de métodos de captura para esses animais, entre os quais se destacam armadilhas tipo covo e pitfall, peneiras, puçás, redes, coleta manual e choque elétrico (ABELE & BLUM, 1977;FIEVET et al, 1996;CREWE et al, 2001;GARCIA et al, 2003;JOHNSON, 2003;ROCHA & BUENO, 2004;MOSSOLIN et al, 2006).…”

ABSTRACT. Differences between two methods used for sampling decapod crustaceans in a stream at Juréia-Itatins Ecological Station, state of São Paulo, Brazil. Sampling collections were taken quarterly from Fall 2000 to Summer 2001 at Juréia-Itatins Ecological Station using two different sampling methods (hand sieve and traps). Comparing both sampling methods one can verify differences in faunal composition, richness, degree of dominance, evenness and size and number of individuals. Moreover, the sex ratio of Macrobrachium acanthurus (Wiegmann, 1836) may differ according to the sampling method. Decapod crustaceans are known to inhabit a great variety of habitats and niches, therefore to obtain an effective qualitative and/or quantitative sampling, in which the majority of decapod species are collected, the use of more than one sampling method is recommended.KEYWORDS. Decapoda, Palaemonidae, Atyidae, Grapsidae, ecology. RESUMO. Durante os anos 2000 e 2001 foram realizadas coletas sazonais de crustáceos decápodes em dois pontos de um rio na EstaçãoEcológica Juréia-Itatins, utilizando-se duas metodologias distintas (peneira e armadilha). Comparando-se ambos os métodos de coleta, foram constatadas diferenças quanto à composição e riqueza da carcinofauna capturada, grau de dominância e equitatividade, bem como tamanho e número de indivíduos coletados. Além disso, as razões sexuais de Macrobrachium acanthurus (Wiegmann, 1836) podem diferir dependendo do método de coleta utilizado. Devido à grande variedade de hábitats e hábitos dos crustáceos, pode-se inferir que, para um levantamento qualitativo e/ou quantitativo eficaz e apurado da comunidade de crustáceos decápodes dulcícolas de um determinado rio, é recomendado o uso de mais de um método de coleta.

“…Following a revision of the western-Atlantic species within this complex, the distribution of the sensu stricto form is presently understood to extend only from southern Florida to Venezuela (Anker, 2012). Some of the previous records of this shrimp in Brazil have been assigned to A. angulosus (Coelho and Ramos, 1972;Christoffersen, 1998;Coelho et al, 2006, in part) and A. carlae (Holthuis, 1956;Mossolin et al, 2006;Pavanelli et al, 2008) (see Anker, 2012). The material reported by Almeida et al (2006Almeida et al ( , 2007aAlmeida et al ( , 2012) from the coast of Bahia was re-examined by us and corresponds to A. carlae and A. angulosus.…”

Time calibrated phylogenies are typically reconstructed with fossil information but for soft‐bodied marine invertebrates that lack hard parts, a fossil record is lacking. In these cases, biogeographic calibrations or the rates of divergence for related taxa are often used. Although nudibranch phylogenies have advanced with the input of molecular data, no study has derived a divergence rate for this diverse group of invertebrates. Here, we use an updated closure date for the Isthmus of Panama (2.8 Ma) to derive the first divergence rates for chromodorid nudibranchs using multigene data from a geminate pair with broad phylogeographic sampling. Examining the species Chromolaichma sedna (Marcus & Marcus, 1967), we uncover deep divergences among eastern Pacific and western Atlantic clades and we erect a new species designation for the latter (Chromolaichma hemera sp. nov.). Next, we discover extensive phylogeographic structure within C. hemera sp. nov. sensu lato, thereby refuting the hypothesis of a recent introduction. Lastly, we derive divergence rates for mitochondrial and nuclear loci that exceed known rates for other gastropods and we highlight significant rate heterogeneity both among markers and taxa. Together, these findings improve understanding of nudibranch systematics and provide rates useful to apply to divergence scenarios in this diverse group.
