Going with the flow? Diversification of gastropods reflects drainage evolution in Africa

open access: yesJournal of Biogeography, Volume 48, Issue 7, Page 1579-1593, July 2021., 2021
Abstract Aim The roles of geodynamics, climatic variability and landscape evolution in shaping aquatic biodiversity patterns on the African continent remain poorly understood. We studied the geographical origin and phylogenetic relationships of an Afrotropical freshwater snail genus to examine the role of drainage evolution on diversification and range
