Chima Nwaogu presents research lecture at Uppsala University, Sweden

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.
