It is predicted that climate change will cause species extinctions and distributional shifts in
coming decades, but data to validate these predictions are relatively scarce. Here, we …

Comprehensive assessments of species’ extinction risks have documented the extinction
crisis 1 and underpinned strategies for reducing those risks 2. Global assessments reveal that, …

Protected Areas (PAs) are the cornerstone of biodiversity conservation. Here, we collated
distributional data for >14,000 (~70% of) species of amphibians and reptiles (herpetofauna) to …

In poorly known groups for which data are insufficient to develop biologically plausible
model-based approaches to phylogeographical analyses, a ‘first hypotheses’ protocol is …
