Covariation of trophic and habitat-related traits in chondrostoms (Cyprinidae) : implications for repeated and diversifying evolutionary processes [Journal of Zoology]

par Frédéric Magné - publié le , mis à jour le

The tenet that ecological adaptation can lead to recurrent ecomorphological trends resulting from repetitive processes has long been a primary topic of investigation in evolutionary ecology. To explore this aspect further, this study provides an analysis of the morphological diversity in chondrostoms (Cyprinidae). This freshwater fish group shows a tendency towards bottom-feeding specialization, which has led to evolutionary innovations in body and mouth shape traits, which are currently used for the classification of genera. Body, lower lip (LL) and corner ray shape were analysed for nine species in total...
