Abstract:Variations in energetic density (E D ) and the relative condition factor (K n ) of juveniles of Prochilodus lineatus were investigated to identify whether these two variables respond similarly to environmental factors. We hypothesized that fluviometric levels in different sub-basins of the Upper Paraná River floodplain positively influence the E D and K n of juvenile fish. Temporally, the values of E D and K n were linked more directly to the dynamics of the flood pulses on the plain. Spatially, the lowest val… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
