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

Journal of Fish Biology, EarlyView.
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 ...

Genetic Structure and Conservation Strategies for the Endangered Catfish Steindachneridion melanodermatum (Siluriformes, Pimelodidae) in the Iguaçu River, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 6, June 2026.
ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu
