Crustáceos decápodos estuarinos de Ilhéus, Bahia, Brasil

Abstract

The carcinofauna from marine and coastal environments from the southeast and southern Bahia, Brazil, is so far poorly known. The objective of this study was to survey decapod crustaceans occurring along the estuarine environments of Ilhéus, located on the southeast coast of Bahia (14 o 47'55"S, 39 o 02'01"W). Samplings were carried out from February 2001 to February 2005, covering supratidal, intertidal and subtidal habitats. Voucher specimens were fixed in ethanol 70% and deposited in the collection of Crustacea of the Universidade Estadual de Santa Cruz, Ilhéus (MZUESC). We report a total of 51 species, belonging to 14 families. The most representative family concerning the number of species was Ocypodidae, represented in our samples by 8 species. Geographic range known for the species Alpheus heterochaelis (Caridea: Alpheidae), Merguia rhizophorae (Caridea: Hippolytidae) and Sesarma curacaoense (Brachyura: Sesarmidae) was enlarged. The IndoPacific portunid crab Charybdis hellerii was recorded for the Cachoeira river estuary. The results indicate a high species richness of decapod crustaceans in the estuarine environments of Ilhéus.

Snapping shrimps of the genus Alpheus Fabricius, 1798 from Brazil (Caridea: Alpheidae): updated checklist and key for identification

“…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. However, most records of A. armillatus in Brazil lack morphological accounts or information about color (e.g., Gomes Corrêa, 1972;Fausto Filho, 1978Sampaio and Fausto Filho, 1984;Coelho et al, 1986;Austregésilo-Filho and RamosPorto, 1995;Young and Serejo, 2005), preventing the determination of the material's identity.…”

“…We listed in previous records only material examined by Christoffersen (1984) and by us (reported by Almeida et al, 2006Almeida et al, , 2012, and the references from Brazil based on these reports (Christoffersen, 1998;Barros and Pimentel, 2001;. All other records (e.g., Kingsley, 1878b; Moreira, 1901;Luederwaldt, 1929;Oliveira, 1940;Coelho, 1964Coelho, , 1966aCoelho, , 1966bCoelho et al, 1970Coelho et al, , 1986Coelho and Ramos, 1972;Gomes Corrêa, 1972;Ramos-Porto et al, 1978;Abreu, 1980;Ramos-Porto, 1980a, 1995;Fausto Filho, 1980;RamosPorto, 1980;Coelho and Coelho-Santos, 1990;Sousa et al, 2000;Bosa and Masunari, 2002;Ferreira and Sankarankutty, 2002;Young and Serejo, 2005;Mortari and Negreiros-Fransozo, 2007;Souza et al, 2011) must be treated with much caution because they potentially include misidentified material.…”

New taxonomic and distributional information on hermit crabs (Crustacea: Anomura: Paguroidea) from the Gulf of Mexico, Caribbean Sea, and Atlantic coast of South America

“…Various faunistic inventories have included summaries of western Atlantic paguroids, often adding new species from the Gulf of Mexico (Felder 1973;Hernández Aguilera et al 1996;Raz-Guzmán et al 1986Felder et al 2009), east and west coasts of Florida (Abele 1986;Strasser & Price 1999), Bermuda (Chace et al 1986), Cuba (Gómez Hernández & Pérez 1984;Gómez Hernández & Martínez-Iglesias 1986;Hernández-Ávila et al 2007), Caribbean coast of Colombia (Sánchez & Campos 1978;Campos et al 2005;Martínez Campos et al 2012) and Venezuela (Rodríguez 1980), Suriname (Holthuis 1959), Brazil (Forest & de Saint Laurent 1968;Fausto-Filho 1970aCoelho & Ramos 1973;Coelho & Santos 1980;Coelho & Ramos-Porto 1986;Hebling & Rieger 1986;Coelho-Santos & Coelho 1995;Calado 1996;Rieger 1997Rieger , 1998Rieger , 1999Melo 1999;Almeida et al 2006Almeida et al , 2010Coelho et al 2007;Nucci & Melo 2011), Uruguay (Barattini & Ureta 1960;de Zolesi & Philippi 1995), and Argentina (Scelzo & Boschi 1973). A good number of studies have also been published in the last 65 years exclusively describing or providing updated taxonomic and distributional data for one or more new or previously poorly known species from the western Atlantic (Forest 1954(Forest , 1964…”

Distribuição geográfica potencial de espécies americanas do caranguejo "violinista" (Uca spp.) (Crustacea, Decapoda) com base em modelagem de nicho ecológico

“…Especificamente, objetivou-se gerar mapas de distribuição potencial dessas espécies e indicar regiões de amostragem com base nos mapas gerados. (CRANE, 1975;BRANCO, 1991;IRIBARNE & MARTINEZ, 1999;ROBALDO & MONSERRAT, 1999;ARMENDÁRIZI & CÉSAR, 2002;THURMAN, 2003;CÉSAR et al, 2005;MASUNARI et al, 2005;ALMEIDA et al, 2006;BEZERRA et al, 2006;MASUNARI, 2006). Este trabalho representa a compilação mais completa de informações desse grupo.…”
