Surviving in the Amazon Arc of Deforestation: Richness and Defaunation of Mammals in Priority‐Protected Areas of the Brazilian Midwest

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
We found rich and compositionally different assemblages of medium and large‐sized mammals in protected areas on the southern edge of Amazon. However, both have high rates of mammal defaunation. We argue that anthropogenic threats in the Amazon Arc of Deforestation are eroding large ungulate populations, especially peccaries.

Successful recovery of native plants post‐invasive removal in forest understories is driven by native community features

open access: yesEcological Applications, Volume 35, Issue 2, March 2025.
Abstract Temperate forest understories hold the majority of the plant diversity present in these ecosystems and play an essential role in the recruitment and establishment of native trees. However, the long‐term persistence of diverse and functional forest understories is threatened by the impacts of invasive plants.

Seasonal acclimation of photosynthetic thermal tolerances in six woody tropical species along a thermal gradient

open access: yesFunctional Ecology, Volume 38, Issue 11, Page 2493-2505, November 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Extreme heat events are becoming increasingly common, and the short‐term acclimation of photosynthesis will have a large impact on plant performance. Trees in lowland tropical forests, which are hypothesized to have limited abilities to tolerate rising temperatures, may

Cattle and nurse trees shape subtropical forest–grassland ecotones

open access: yesJournal 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 ...
