Forest Guardians: The Role of Dense Forests and Water Networks in Supporting Lowland Tapir (Tapirus terrestris) Populations in the Orinoquia Region of Colombia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Our study reveals that lowland tapir (Tapirus terrestris ) occupancy in Colombia's Orinoquia region is strongly influenced by dense forests and proximity to water bodies, while anthropogenic factors such as pastures and road networks negatively impact their presence.

Migration and forests in the Peruvian Amazon: a review [PDF]

open access: yes, 2019
This paper reviews the literature on the links between migration and forests in the Peruvian Amazon. It highlights not only the complexity of the migrant–forest interface in Peru but also the relative lack of research on these dynamics.

Use of community characteristics to predict hunting and game harvests in western Amazonian forests

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Wild game harvesting in Amazonia provides rural residents with protein and cash income but can threaten wildlife populations and forest ecosystem functions. As yet, the socioeconomic and environmental drivers that shape hunter livelihoods remain poorly understood.

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

open access: yesEcological 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

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 ...

Diversity and dominance in bird assemblages across habitats in the Ñeembucú wetlands complex

open access: yesBiotropica, Volume 56, Issue 5, September 2024.
We analyzed how the composition of neotropical bird assemblages vary among habitats (riparian forests, natural grasslands, savannas, and anthropized sites) in the Ñeembucú Wetlands Complex, the largest wetland system in Paraguay. We found a high bird richness (209 species) that contrasted with a pattern of dominance by a small set of 16 species that ...
