Australian flying fox die-offs
In the last two decades tens of thousands of Australian flying foxes have died during extreme heat events. Flying fox die-offs feature arguably among the most dramatic mass mortality events witnessed in nature, but they can be indicators of heat stress in more cryptic fauna where impacts are more difficult to assess. The die-offs are important additional threats to Australian flying-foxes and the ecosystem services they provide, and highlight the complex implications of climate change for behaviour, demography, and species survival.
==Impacts on species==
Two Australian flying fox species have reportedly been affected by extreme heat events: the grey-headed flying fox (''Pteropus poliocephalus'') and the black flying fox (''P. alecto''). Where mixed-species colonies are affected the black flying fox suffers substantially higher mortality than the grey-headed flying fox.〔 However, summer temperatures are more extreme within the range of the grey-headed flying fox than within the range of the black flying-fox, and therefore the actual total number of casualties is much higher among grey-headed flying foxes than black flying foxes.
