Assessing introgressive hybridization in roan antelope (Hippotragus equinus): Lessons from South Africa.

open access: yesPLoS ONE, 2019
Biological diversity is being lost at unprecedented rates, with genetic admixture and introgression presenting major threats to biodiversity. Our ability to accurately identify introgression is critical to manage species, obtain insights into ...

Interspecific Cohabitation and Associated Zoonotic Risk in the Burrows of Niokolo‐Koba National Park, Senegal

open access: yesEcology and Evolution, Volume 16, Issue 11, November 2026.
Burrows concentrate multiple species in confined spaces, potentially facilitating pathogen transmission. Camera traps at 105 burrow entrances in Niokolo‐Koba National Park documented 32 species generating 172 interspecific cohabitations. Potential zoonotic bacteria (Treponema, Francisella) were detected, and ticks were found in half of sampled burrows,

Reduction of Tree Water Stress by Large Herbivores in an African Savanna

open access: yesEcology Letters, Volume 29, Issue 11, November 2026.
Using a long‐term herbivore exclusion experiment across a rainfall gradient, we found that excluding large mammals increased savanna tree growth but elevated water stress. Tree sensitivity to exclusion varied among species with contrasting water‐use strategies, indicating that physiological responses may drive shifts in tree communities under altered ...

The variability of giraffe skull morphology

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 1068-1086, November 2026.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head
