Cacao grafting increases crop yield without compromising biodiversity

Journal of Applied Ecology, Volume 62, Issue 3, Page 579-592, March 2025.
Grafting is a successful approach for rejuvenating old, unproductive cacao trees, enhancing smallholder income opportunities and thus reducing pressure for new deforestation‐based plantations. Grafting briefly reduced arthropod abundance and diversity, but recovered in a short time.

Rancher viewpoint diversity in human–wildlife coexistence management: The case of jaguar–livestock interaction in the region of Calakmul, Mexico

People and Nature, Volume 7, Issue 1, Page 67-80, January 2025.
Abstract Protected areas in Latin America are typically surrounded by ranching landscapes, where large carnivores such as the jaguar (Panthera onca), co‐habit with ranchers, which potentially causes negative interactions. It is crucial, however, recognize that effective coexistence hinges on developing conservation policies that not only address these ...

Aridity and forest age mediate landscape scale patterns of tropical forest resistance to cyclonic storms

Journal of Ecology, Volume 113, Issue 1, Page 53-67, January 2025.
These findings show that selection towards drought‐tolerant traits across aridity gradients, such as short stature and dense wood, enhances resistance to hurricanes. However, forest age modulated responses to hurricanes, with older forests being less resistant across the islands.

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 ...

Land use history and landscape forest cover determine tropical forest recovery

Journal of Applied Ecology, Volume 61, Issue 10, Page 2365-2381, October 2024.
Both a higher land use intensity and fragmented forest landscape decreases the speed of forest recovery, indicating that human actions and landscape transformation shape the course of succession. Restoration in fragmented forest landscapes through natural regeneration is more suitable in areas with low previous land use intensity, higher forest ...

Rates of tree cover loss in key biodiversity areas on Indigenous Peoples’ lands

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Indigenous Peoples’ lands (IPL) cover at least 38 million km2 (28.1%) of Earth's terrestrial surface. These lands can be important for biodiversity conservation. Around 20.7% of IPL intersect areas protected by government (PAs). Many sites of importance for biodiversity within IPL could make a substantial but hitherto unquantified contribution
