Dr Gabriel Jamie and Dr Joana Meier’s paper on the persistence of polymorphisms across species radiations is on the front cover of the September issue of Trends in Ecology and Evolution. The cover image provides a specific example of the trans-species polymorphisms that the paper explores. Here, a polymorphism in shell chirality that recurs across multiple species of Amphidromus snails . Photos by Menno & Jan Schilthuizen.

Dr Chima Nwaogu visited the Animal Ecology Unit at the Evolutionsbiologisk centrum (EBC) at Uppsala University, Sweden, to present the 2025 Christer Hemborg lecture. He gave a research lecture on why Afrotropical birds breed when they do, based on analyses of breeding records derived from Major John Colebrook-Robjent’s egg collection currently held at the Livingstone Museum. He explored how the effects of pre-rain tree green-up and rainfall onset differentially drive invertebrate and grass seed abundance, influencing multiple seasonal bird breeding patterns throughout the year.
