Última Hermaphroditism of bivalves Anadara tuberculosa and Anadara similis Sowerby 1883 (Arcidae) in Colombian Pacific mangroves Boletín de Investigaciones Lucero Rincon,Carlos H.; Cantera Kintz,Jaime R.; Gil-Agudelo,Diego L.. ABSTRACT The hermaphrodite condition of the cockles Anadara tuberculosa and Anadara similis, gonochoric species living in mangroves of the Pacific coast of Colombia, are described in this paper. The gonads of 290 individuals of A. tuberculosa and 336 individuals of A. similis collected in five localities of the Colombian Pacific coast were analyzed using histological methods. Our results exposed that 3.1 % of A. tuberculosa and 3.0 % of A. similis analyzed showed signs of both ovules and spermatozoids, as well as simultaneous sexual maturation. Based on this frequency of occurrence of hermaphrodite individuals and the fact that hermaphrodite organisms were present in most of the sampling sites, we conclude that hermaphroditism is a normal rather than...

ABSTRACT The Cortez rainbow wrasse, Thalassoma lucasanum, is an abundant reef fish of the Eastern Tropical Pacific (ETP). Unlike other species of the genus Thalassoma that are recognized as cleaners, in T. lucasanum this behavior is rare, since it feeds mainly on invertebrates through foraging. However, information on the trophic ecology of this species is limited, especially in the ETP. In this study, we characterize the feeding habits of T. lucasanum in Gorgona Island (ETP) from analyzing its gut contents and calculating its trophic niche. Mollusks were the main food resource of T. lucasanum, being this the most important and frequent prey item found in 100 % of the stomachs analyzed (n = 5). In terms of biomass, crustaceans had the greatest contribution... Tipo: Info:eu-repo/semantics/article Palavras-chave: Coral reef fish; Stomach content; Trophic interactions; Colombian Pacific..
