Sublethal effects of extreme heat on a critically endangered marsupial

Context Extreme heat events are intensifying under climate change, yet their sublethal effects on threatened mammals remain poorly understood. Aims We investigated behavioural responses of the critically endangered western ringtail possum (Pseudocheirus occidentalis; ngwayir) to extreme heat on the Southern Swan Coastal Plain of Western Australia. Methods Using tri-axial accelerometer collars, we quantified diel activity patterns of 10 ngwayirs across two peppermint (Agonis flexuosa) woodland po
