TITLE:

Exploring the phylogenetic relatedness among a carnivorous fish assemblage

KEY WORDS:

predator species; niche breadth; phylogenetic signal

SUMMARY:

Species share ecological similarities due to a common evolutionary history recognized by the phylogenetic signal between the trait of interest and the phylogeny. We address this question by examining the shared evolutionary history between fish species, particularly in estuarine and coastal fishes, using their diet composition as a functional trait. We studied the diet and trophic niche breadth of 69 species, including species with a wide range of prey items, with two main groups identified, carnivorous and piscivorous fishes. According to our results, the phylogenetic signal of niche breadth was weak among coastal fishes, while changes in diet and niche width were correlated to seasons, suggesting that environmental filters mainly control the predatory fish community. This work contributes to understanding how phylogenetic relatedness explains differentiation in the trophic dimension of the niche of fish species coexisting in coastal areas.
