Congratulations to Dr Chima Nwaogu for his award of a British Ecological Society “Ecologists in Africa” grant to start his new programme of research in Zambia entitled “Why do Afrotropical birds breed when they do?“, based at the FitzPatrick Institute of Ornithology at the University of Cape Town. Thank you to the BES for this wonderful support!
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.
Our paper “Pigment concentrations only partially predict avian eggshell colour mimicry in a polymorphic host–brood parasite system” has been published in the journal Biology Letters.
Mairenn Attwood’s paper ‘How do parasites and predators choose their victim? A trade-off between quality and vulnerability across antagonistic interactions’ is out now in the journal Biological Reviews.
Our paper “How animals discriminate between stimulus magnitudes: a meta-analysis” has been published in the journal Behavioral Ecology.
