A new study published in Australian Mammalogy has challenged long-held assumptions about the gliding ability of the greater glider, a marsupial native to Australia. The research, conducted by conservation biologists at the Australian National University, used infrared binoculars, lasers, and tape measures to track 41 'flights' in New South Wales forests.
The study found that the average distance travelled by greater gliders is just 19 metres, far shorter than the 100 metres previously suggested. The longest recorded flight was less than 50 metres. Despite this, the researchers note that witnessing a greater glider in action can still be breathtaking.
Dr Ana Gracanin, the lead author of the study, explained that the term 'greater' refers to the animal's large body size rather than its gliding distance. She noted that the gliders use a membrane stretching from their elbows to their ankles to stay aloft, allowing them to cover short distances with impressive agility.
The study's findings have significant implications for conservation efforts, particularly in light of the species' reliance on tree cover to travel and forage. Gaps created by logging or infrastructure development could stymie the movement of greater gliders, making conservation efforts more challenging.
