Pleistocene Forest Stability Predicts Patterns of Frog Diversity in Central Africa

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Using high‐resolution paleoclimate reconstructions, we quantified habitat stability for Central African rainforests across 257 time slices since the early Pleistocene. Stacked projections of forest‐dependent frog niches identify both a large, continuous refugium and smaller, highly stable forest blocks embedded within today's forest cover.

Detecting and attributing climate change effects on vegetation: Australia as a test case

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 461-485, March 2026.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Microrefugia and species persistence in the Galápagos highlands: A 26,000-year paleoecological perspective.

open access: yesFrontiers in Genetics, 2013
The Galápagos Islands are known to have experienced significant drought during the Quaternary. The loss of mesophytic upland habitats has been suggested to underlie the relatively lower endemism of upland compared with lowland plant assemblages.
