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 ...
