Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone

Ecology and Evolution, Volume 15, Issue 9, September 2025.
We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

Urban developmental environments alter tadpole phenotypes depending on origin

Journal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.
