A New Method of Fruit Marking for Studies on Chiropterochory

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
We used edible glitter to mark 15,526 fruits of three chiropterochorous plants at 700, 1000, 2000, and 3200 m from a bat roost in Brazil's caatinga. Glitter from all distances was detected at the roost, allowing the identification of specific feeding areas accessed, providing a new approach for zoochory studies.

Comparative analysis of machine learning algorithms and vegetation indices for mapping Eucalyptus tree woodlots using Sentinel‐2 imagery in the Akaki River catchments

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Eucalyptus trees (ETs) cover approximately 20 million ha globally, with Brazil leading at 5.6 million ha. In Africa, ET plantations span around 1.5 million ha, primarily in South Africa and Ethiopia. In Ethiopia, ET plays a key role in agroforestry, covering 506,000 ha, which represents 90% of all planted trees in the form of woodlots.

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.
