“…In both of these sites, the most abundant species was Latreutes fucorum (Fabricius, 1798) (Hippolytidae) (Bauer, 1985a,b;De Grave et al, 2006). In our study, the dominant species include Hippolyte obliquimanus and Latreutes parvulus (Hippolytidae).…”

“…Push net samplings, similar to the one we used, have found richness of 23 species in Puerto Rico (Bauer, 1985a,b) and of 14 species in Honduras (De Grave et al, 2006). In both of these sites, the most abundant species was Latreutes fucorum (Fabricius, 1798) (Hippolytidae) (Bauer, 1985a,b;De Grave et al, 2006).…”

“…In the Caribbean area, the most abundant decapods are usually carideans belonging to the family Hyppolytidae, within the genera Hippolyte, Latreutes, Tozeuma and Thor (Heck, 1979;Lewis, 1984;Bauer, 1985a,b;Holmquist et al, 1989;De Grave et al, 2006;Aguirre-Aguirre et al, 2007). Our results partially agree with these reports: individuals in the genera Latreutes and Hippolyte accounted for 67% of the total individuals for the El Supí locality.…”

ABSTRACT. Thalassia testudinum and Halodule wrigthii are the dominant seagrasses in the Caribbean, being common across shallow shorelines, either as monospecific or as intermixed meadows. Among the macrofauna associated with these beds, crustaceans are considered essential for the whole ecosystem functioning. However, knowledge about the associated community of decapod crustaceans in assemblages of T. testudinum and H. wrigthii is still scarce, particularly outside of protected areas. Here we report eight new decapod species for the Paraguaná Peninsula (Falcón State, Venezuela) Manning & Chace, 1971. These records represent habitat extensions and fill gaps in the geographical distribution of the species along the northern coast of South America. Furthermore, we found that statistical differences in decapod species abundance and composition are likely to be caused by the joint action of coverage and heterogeneity of the beds. Our results indicate that typical Caribbean species were the most influential in the community; nevertheless, the abundance of juvenile Penaeus schmitti Burkenroad, 1936 was notable, since they have rarely been found in these habitats. This finding highlights the role of non-protected areas as nursery habitats for economically important species. Our results show that seagrass meadows in the Paraguaná Peninsula reflect overall good health when compared to other Caribbean zones, representing an important habitat for the maintenance of crustacean populations.KEYWORDS.

Composición y abundancia de crustáceos decápodos en praderas mixtas de hierbas marinas en la península de Paraguaná, Venezuela. Thalassia testudinum y Halodule wrigthii son las hierbas marinas dominantes en el Caribe, siendo comunes en costas someras, tanto en monocultivos como en cultivos mixtos. Entre la macrofauna asociada a estas comunidades, los crustáceos son considerados esenciales para el funcionamiento del ecosistema. Sin embargo, el conocimiento sobre la comunidad de crustáceos decápodos asociada a praderas mixtas de T. testudinum y H. wrigthii es escaso, en particular fuera de zonas protegidas. En este trabajo presentamos ocho nuevas especies de decápodos para la Península de Paraguaná (estado Falcón, Venezuela) asociados a praderas mixtas de hierbas marinas: Achelous tumidulus Stimpson, 1871, Alpheus floridanus Kingsley, 1878, Chorinus heros (Herbst, 1790), Clibanarius antillensis (Stimpson, 1859), Clibanarius sclopetarius (Herbst, 1796), Latreutes parvulus (Stimpson, 1866), Panopeus occidentalis Saussure, 1857, y Processa fimbriata Manning & Chace, 1971. Estos registros representan extensiones de hábitat y completan brechas en la distribución geográfica de las especies a lo largo de la costa septentrional de Sudamérica. Diferencias estadísticas en la abundancia y composición de las especies de decápodos fueron posiblemente causadas por la acción conjunta de cobertura y heterogeneidad de las praderas. Las especies más influyentes e...

“…Caridean shrimps are important faunal components of temperate and tropical seagrass meadow ecosystems (e.g. Kikuchi 1962Kikuchi , 1966Bauer 1985Bauer , 1989Bauer , 2004De Grave et al 2006). Considerable temporal variation in breeding patterns occurs in caridean species.…”

“…Caridean shrimps are often a dominant faunal group in seagrass beds and include carnivorous and herbivorous species (Heck 1977;Saloman 1979;Gore et al 1981;García Raso et al 2006;Unsworth et al 2007). Shrimps are an important link between primary production and higher trophic levels (Kikuchi 1966;De Grave et al 2006;Unsworth et al 2007). Studies using nocturnal sampling have shown that carideans of the family Processidae may be abundant in seagrass meadows (Kikuchi 1962(Kikuchi , 1966Leber 1983;Bauer 1985;De Grave et al 2006).…”

The purpose of the current study was to analyse the reproductive ecology and sexual system in Ambidexter symmetricus (Processidae), a nocturnal seagrass shrimp. This work was conducted in St Joseph Bay, Florida, in May–August 2010 and April–October 2011. The sex ratio in A. symmetricus and the presence of juvenile females supported the hypothesis of a gonochoric sexual system. Breeding in the population occurred seasonally from April until September. Successive spawning of individual females was shown by the presence of late-stage (prespawning) ovaries in females that were brooding late-stage (near hatching) embryos. Female A. symmetricus were generally larger and more abundant than males. Male A. symmetricus with parasites exhibited gigantism. Because of seasonal differences in recruitment and growth, body size varied with time of year, with larger (overwintered) individuals collected in April and May, and smaller more recently recruited individuals more abundant in September and October. The population biology of this species is similar to many other warm-temperate, shallow-water carideans, thus supporting hypotheses about latitudinal variation in breeding and recruitment in marine benthic invertebrates.
