Koalas may be more vulnerable to heat than we thought.
Researchers, including Joy Tripovich from the UNSW School of Bees published in Biology Letters, analysed more than 11,800 koala rescue records and found out that the higher the temperature, the greater the odds of admission into care or death.
Temperatures over 30 degrees increased the odds of admission or death up to 3.5 times compared to temperatures of 25 degrees.
Inland north-west populations were identified as the most at risk.
The study also suggests heat stress may worsen disease impacts in koalas, particularly chlamydiosis, while habitat loss reduces access to cooler refuge areas like dense forests and shady trees.
