River barriers have long played a central role in diversification models of tropical regions, including the exceptionally biodiverse island Madagascar. Although their role is best understood by integrating additional factors such as elevation and the ecological niche of a species, empirical studies integrating these variables remain rare. We used restriction site‐associated DNA sequencing to assess the combined effect of river...

Wildfires significantly threaten biodiversity, especially in tropical regions like Madagascar, where unique ecosystems face ongoing habitat loss and degradation. This study investigated the effects of forest fires on lemur encounter rates, species richness, and their ability to recolonize burnt areas in Ankarafantsika National Park (ANP), the largest protected dry deciduous forest in northwestern Madagascar. ANP hosts eight le...
