Energetic and oxidative costs of microfilarial infection: evidence for fitness trade‐offs in male village weavers of the Amurum Forest Reserve

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
Microfilariae contribute to a higher energetic demand that could lead to oxidative damage and reduce hosts' fitness. Yet reports about the energy status and oxidative stress‐defense mechanisms of infected wild birds are rarely documented. We investigated the relationship between microfilariae and the energy status and oxidative damage‐defense ...

Diet and Foraging in the Waibira Chimpanzee Community, Budongo Central Forest Reserve, Uganda

open access: yesAmerican Journal of Primatology, Volume 87, Issue 12, December 2025.
ABSTRACT Foraging is a fundamental aspect of the behavioural ecology of any species. Chimpanzees (Pan troglodytes) are generalist omnivores that inhabit a continuous range of forest environments. Accordingly, substantial differences in feeding ecology exist across chimpanzee sub‐species and populations.

Mechanism of endocarp-imposed constraints of germination of Lannea microcarpa seeds [PDF]

open access: yes, 2008
Lannea microcarpa, a multipurpose tree species from the dry African savanna, sheds seeds that often display inhibition of germination. The underlying mechanism was investigated using seeds processed from fully matured fruits collected from natural stands

Evaluating the determinants of deforestation and approaches to reforestation by cocoa farmers in Côte d'Ivoire

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1674-1683, November 2025.
Cocoa‐driven deforestation threatens tropical forests, particularly in Côte d'Ivoire, the world's largest cocoa producer. This study examines the motivations behind cocoa cultivation in classified forests, the selection of retained tree species on farms, and the economic drivers of wooded lands conservation among farmers.
