High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods

Journal of Fish Biology, Volume 109, Issue 2, Page 1034-1045, August 2026.
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...
