Surveys revealing new species and endemism “hotspots” have just started to uncover true biodiversity levels within the remote tropical savannahs of the Kimberley (Western Australia). Using geckos as a model system I took a comparative phylogeographic approach, integrating advanced next-generation genetics and morphology to assess diversity patterns across ecologically variable taxa. I discovered high levels of cryptic diversity and possible “refugia” where diversity persists through harsh conditions. These findings indicate diversification patterns are shaped by complex interactions of climatic variation, topography, and species’ ecology, allowing inference of biogeographic history and a greater ability to predict impacts of future environmental change.
