Composición Y Estructura Del Ensamblaje De Crustáceos Brachyura De La Plataforma Continental De La Guajira Colombiana Y Su Relación Con La Profundidad Y Las Características Del Sedimento

Abstract: Brachyura crustaceans composition and structure assemblage along be continental shelf of La Guajira and its variation according to depth gradient and sediment characteristics were determined. 44 bottom drag samples were taken at 10 and 50 m depth using a semi globe demersal net, during March and April 2005. 83 species belonging to 21 families were identified; the most important families due to their abundance of specimens and amount of species were Goneplacidae, Portunidae, and Mithracidae; and dominant specie… Show more

“…Further, the dominance of a few species also affects community structure. These findings are in line with data reported by Gómez-Lemos et al (2010), who showed that depth was one of the main factors that affected the composition of the assemblage.…”

“…Even though knowledge regarding the composition of the brachyuran crab assemblages in the area is available, understanding its interaction with shrimp fishing in the central-southern portion of Veracruz is scarce since most previous studies have been inventories and taxonomic studies (Gómez-Lemos et al 2010). The fishing activity involves removing species due to shrimp trawling and the low selectivity of fishing nets.…”

“…R values between 0.75 and 1 indicate that ordinations are completely different, and values between 0 and 0.25 indicate that there is minimal difference [54]. This is a robust test for comparing and validating the affinity between ecological compositional arrangements [55,56].…”

“…La mayoría de las especies se encontraron dentro del rango de distribución batimétrica reportado previamente por otros autores en el mundo (FELDER et al, 2009;HOLTHUIS, 1991;KING, 1984;KOMAI y KOMATSU, 2009;PEQUEGNAT & PEQUEGNAT, 1970;PÉREZ-FARFANTE & BULLIS 1973;WILLIAMS, 1984;POUPIN, 1994;RATHBUN, 1937) y para Colombia (CAMPOS et al, 2005;GÓMEZ-LEMOS et al, 2010;PARAMO et al, 2017), con excepción de P. politus que solo se había registrado hasta los 330 m (FELDER et al, 2009) y en el presente estudio se capturó por encima de los 400 m (Figura 2). La amplia distribución de profundidad de algunos crustáceos decápodos se debe a que mantienen un alto metabolismo a través de su comportamiento nectobentónico (COMPANY & SARDÀ, 1998) y son capaces de movilizarse a áreas de alimentación más favorables.…”
