Viability of Seeds Consumed by Fishes in a Lowland Forest in the Brazilian Central Amazon

Abstract: Várzeas are forest areas seasonally flooded by white-water rivers and have a variety of tree species, which bear fruit during the filling or flood and in the beginning of low water periods. During those periods of inundation, fruits and seeds are important resources for different fish species. In this study, the viability of whole seeds removed from the stomach and intestine of fishes was analyzed. Fishes were collected with gillnets installed during 24-hr cycles along the flooded forest, during the filling, f… Show more

“…However, after construction of a hydroelectric dam, the flood pulse is controlled by the closing and opening of the dam's floodgates-driven by the demand for electricity (MME, 2007)which affects, among other properties, riverine connectivity. The lateral connectivity in natural riparian forest, between river channel and floodplain, and the longitudinal connectivity between the river's upstream and downstream systems (Ward, 1989), are important by both ways for the dispersal of seeds by water and fish, contributing to the structure of plant communities and maintaining the diversity and distribution of wetland vegetation along the Amazonian rivers (Gottsberger, 1978;Junk et al, 1989;Weiss, Zuanon & Piedade, 2016).…”

“…El ítem crustáceos estuvo presente en menor proporción (15%) y los insectos fueron los menos representativos (1%) (Figura 1). Reportes en la Amazonía mencionan que la mota consume un bajo número de semillas en relación a las especies de Characiformes (Santos et al, 2006;Weiss et al, 2016). Sin embargo, nuestros resultados muestran que frutos y semillas constituyen una parte importante (37%) de la dieta de la mota en la Amazonía peruana.…”

“…Sin embargo, nuestros resultados muestran que frutos y semillas constituyen una parte importante (37%) de la dieta de la mota en la Amazonía peruana. Al igual que algunas otras especies de bagres, C. macropterus es considerado un dispersor de semillas (Weiss et al, 2016) que contribuye a que estos sean esparcidos a grandes distancias por la capacidad que tienen de realizar largas migraciones (Usma et al, 2013). Desempeñando de esta manera un papel importante en la ecología de los bosques inundados haciendo que nuevas áreas sean colonizadas a lo largo de los diferentes ríos (Weiss et al, 2016).…”
