New records of portunid crabs (Decapoda: Brachyura: Portunidae) from Sergipe, NE Brazil

Abstract

Four portunid crabs species, including an exotic one, are recorded for the first time from the state of Sergipe, NE Brazil. Although common along the Brazilian coast, the new records of the crabs Callinectes bocourti A. Milne-Edwards, 1879, C. exasperatus (Gerstaecker, 1856), C. marginatus (A. Milne-Edwards, 1861) and Charybdis hellerii (A. Milne-Edwards, 1867) (Decapoda, Brachyura, Portunidae) reflect the poor knowledge about crustacean fauna in the state of Sergipe, and reinforce the need for systematic surveys to better understand the local biodiversity.

Composition of the biofouling community associated with oyster culture in an Amazon estuary, Pará State, North Brazil

“…Globally, bivalve aquaculture is affected by biofouling via settlement on the shell surface of cultivated target species and/or on the culture systems, which can be submersed (e.g., long line) or fixed in intertidal zones (e.g., tables with pillows, lanterns and bags) (Fitridge et al 2012, Sievers et al 2013, 2014Lacoste & Gaertner-Mazouni 2015, Chagas 2016.…”

“…In the laboratory, the biofouling community underwent an initial screening process, whereby organisms were separated into broad taxonomic groups, and preserved in 70% ethanol for further quantitative analysis and taxonomic identification under a stereomicroscope. Each organism was identified to the lower possible resolution using a variety of available sources, such as: crustaceans (Coelho & Ramos-Porto 1992, Poore 2004, Bezerra & Júnior 2006, Valencia & Campo 2007, Almeida et al 2013, Soledade & Almeida 2013, Rosa 2014, molluscs (bivalves and gastropods) (Rios 1994, Leme 1995, Abbott & Dance 2000, Leal 2002aDenadai et al 2006, Matthews-Cascon & Lotufo 2006, Barroso et al 2013, Amaral & Simone 2014, cnidaria (Dias et al 2007) and polychaetes (Amaral & Nonato 1981, Uebelacker & Johnson 1984, Amaral & Nonato 1996, Santos & Lana 2001, Saiki 2010, Amaral et al 2013.…”

New records of decapod crustaceans from the coast of Sergipe state, Brazil

“…This research, which aimed to evaluate the decapod fauna of the state recorded about 40 species and was subsequently expanded by Coelho et al (2004), which added 11 new species. More recently, other eight species were recorded in this region by the studies of Hirose (2012), Rosa and Almeida (2012), Rosa (2013Rosa ( , 2014 and Sousa et al (2014). In this study, we expanded the knowledge of this fauna in the state of Sergipe with the recording of seven additional decapod species.…”

“…Decapod crustaceans represent one of the most important groups of the megafauna in the consolidated and unconsolidated sublittoral, mostly comprising members of the infraorders Caridea, Brachyura and Anomura (Martin and Davis 2001;De Grave et al 2009). The distribution of decapod crustaceans along the Brazilian coast is constantly changing, not only with an increasing number of species that inhabit these waters via the introduction of exotic species (Tavares and Amouroux 2003;Tavares and Mendonça 2004;Almeida et al 2012b), or description of new species (Brandão et al 2012;Almeida et al 2013Almeida et al , 2014, but also by the expansion of the distribution limits of these organisms (Martinelli and Isaac 2001;Targino et al 2001;Cobo et al 2002;Alves et al 2006;Camargo et al 2010;Hirose 2012;Rosa and Almeida 2012;Rosa 2013Rosa , 2014Sousa et al 2014;Barros-Alves et al in press). However, studies that aim to describe the diversity of the decapod crustaceans in some states in the north and northeast of Brazil are still scarce.…”

A tribute to Michael Türkay (3 April 1948 - 9 September 2015): contributions and legacy of a lifelong study on New World decapods, and personal impressions

“…They hypothesized that the most probable origin for the specimens found in Colombia was the Israeli coast, and postulated that the success of the introduction could only be assessed in the future. This publication was eventually followed by a steady stream of papers recording this species from Florida (USA) to Santa Catarina (southern Brazil) (Lemaitre, 1995;Mantelatto and Dias, 1999;Tavares, 2011;Bentes et al, 2013;Rosa, 2014; see…”
