Ecological and functional effects of habitat conversion and seasons on fruit‐feeding butterfly assemblages in tropical dry forests Efeitos ecológicos e funcionais da conversão do habitat e da sazonalidade sobre assembleias de borboletas frugívoras em florestas tropicais secas

open access: yesEcological Entomology, EarlyView.
Land‐use change and seasonality shape the taxonomic, functional and phylogenetic diversity of fruit‐feeding butterflies in tropical dry forests. Pastures reduce phylogenetic diversity and increase wing fluctuating asymmetry, while taxonomic and functional diversity is greater in the wet season than in the dry season.
