Defining environmental and physiological requirements to guide conservation actions for range-restricted frog species in a drying climate

In the current global biodiversity extinction crisis, amphibians are one of the most threatened groups of animals. For many
amphibian species, the reason for their decline is unclear, as is how they will be impacted by climate change. This thesis
focuses on threatened terrestrial-breeding frogs (Geocrinia alba and Geocrinia vitellina) that occur in forest drainages in
southwest Western Australia, a region that is becoming drier and warmer. This thesis determines that drying conditions were a
principal driver of recent G. alba declines, that both frog species have specialised habitat and physiological requirements, and
that climate change is an immediate threat.
