Impacts of river fragmentation on limiting individual dietary specialization of Amazonian predatory fish

Autor: Jamerson Aguiar-Santos, Pieter deHart, Bruce Forsberg, Carlos Freitas

Publikováno v: PeerJ, Vol 10, p e14266 (2022)

Individual dietary specialization is one of the factors that promotes variation in resource use at the individual level. Here we used stable isotope analysis of multiple tissues with different turnover rates to examine the degree of individual specia

SEASONAL AND SPATIAL DYNAMIC OF SMALL SCALE FISHERIES IN CENTRAL AMAZONIA

Autor: Carlos Edwar de Carvalho Freitas, Vinícius Verona Carvalho Gonçalves, Jamerson Aguiar Santos

Publikováno v: Terceira Margem Amazônia. 6:206-223

Amazonia is considered to host some of the more productive freshwater fisheries of the world, and these are of key importance to the local population. Accordingly, fishing activity needs to be studied to evaluate its dynamics, so that long-term susta

Isotopic niche alteration of a predator fish in a dammed Amazonian black water river

Autor: Bruce Forsberg, Carlos Freitas, Pieter DeHart, Jamerson Aguiar-Santos

Publikováno v: Journal of fish biologyREFERENCES. 101(6)

Although many upstream effects of a dam on the trophic ecology of fish have been reported, little is known about their downstream effects on the isotopic niche of Amazonian predator fish. The authors used stable isotope analysis of δ
