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 ...

Tropical forest above‐ground productivity is maintained by nutrients cycled in litter
Journal of Ecology, Volume 112, Issue 4, Page 690-700, April 2024.The maintenance of highly productive lowland tropical forests on infertile soils is often attributed to nutrient cycling via litterfall. Almost 40 years after this theory was first proposed, our large‐scale field experiment demonstrates that tree growth and litter production decline in response to long‐term litter removal, providing the first empirical
