Australian rodent named the 1st mammal to go extinct due to human-caused climate change
An Australian rodent found only on a tiny island on the Great Barrier Reef has been declared extinct. Scientists say it's the first mammal known to be wiped out by human-caused climate change.
The Bramble Cay melomys, which looked like a small brown rat, lived on Bramble Cay, a hump of coral just 340 metres long and 150 metres wide that juts out three metres or less above the water between Queensland in Australia and Papua New Guinea.
But a thorough survey using small animal traps, camera traps and daytime searches from August and September 2014 failed to turn up any of the animals, says a new report written by Ian Gynther from Queensland's Department of Environment of Heritage Protection and Natalie Waller and Luke Leung at the University of Queensland and released today.
The report said the "key factor" responsible for killing off the animals was flooding of their island on multiple occasions during the last decade, "causing dramatic habitat loss" and possibly killing some individuals directly.
"Available information about sea-level rise and the increased frequency and intensity of weather events producing extreme high water levels and damaging storm surges in the Torres Strait region over this period point to human-induced climate change being the root cause of the loss of the Bramble Cay melomys," the researchers added. "Significantly, this probably represents the first recorded mammalian extinction due to anthropogenic climate change."
