Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Ecological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.

Cattle and nurse trees shape subtropical forest–grassland ecotones
Journal of Applied Ecology, Volume 61, Issue 10, Page 2430-2443, October 2024.Tree cover can potentially expand on the subtropical South American grasslands. Reductions in cattle densities and increases in rainfall levels associated with climate change could facilitate forest expansion in this region. Abstract South American subtropical landscapes are dominated by open grasslands and mosaics of forest–grassland formations ...
