Media Release: Megafaunal extinctions driven by too much moisture

Studies of bones from Ice Age megafaunal animals across Eurasia and the Americas have revealed that major increases in environmental moisture occurred just before many species suddenly became extinct around 11-15,000 years ago. The persistent moisture resulting from melting permafrost and glaciers caused widespread glacial-age grasslands to be rapidly replaced by peatlands and bogs, fragmenting […]

Media release: Temporary extinction reprieve for some frogs

Australian scientists have good news for frog conservation ─ there may be longer than expected time to intervene before climate change causes extinction of some species. The scientists used new methods for modelling the threat of climate change on frogs in tropical north-eastern Australia and showed that, at least for some species, there is likely […]

Dingo wrongly blamed for extinctions

Dingoes have been unjustly blamed for the extinctions on the Australian mainland of the Tasmanian tiger (or thylacine) and the Tasmanian devil, a University of Adelaide study has found. In a paper published in the journal Ecology, the researchers say that despite popular belief that the Australian dingo was to blame for the demise of […]

Making national parks truly national.

Environment Insitute member Corey Bradshaw co-authored this piece on The Conversation on June 14, 2013. Australia boasts over 500 national parks covering 28 million hectares of land, or about 3.6% of Australia. You could be forgiven for thinking we’re doing well in the biodiversity-conservation game. But did you know that of those more than 500 […]

Endangered species: could better tracking methods reduce vulnerability or extinction?

Guest blogger botanist Craig Costion has written an article on endangered species on Biodiversity Revolution‘s blog which describes a new approach to developing the International Union for Conservation of Nature’s (IUCN) classification for potentially endangered species for which no demographic information is available. The term ‘endangered species’ refers to species which fall under the IUCN’s […]

New Paper – No need for disease: testing extinction hypotheses for the thylacine using multi-species metamodels

A new paper involving Environment Institute members Thomas Prowse, Corey Bradshaw (also SARDI), Michael Watts and Barry Brook as well as Christopher Johnson (University of Tasmania), Robert Lacy (Chicago Zoological Society) and John Pollak (Cornell University) has recently been published in the Journal of Animal Ecology. The paper titled ‘No need for disease: testing extinction […]

Ancient genes may explain modern threat to Tasmanian devils

Researchers at the University of Sydney and the University of Adelaide have discovered that Tasmanian devils had low immune gene diversity for hundreds, and possibly thousands, of years before the emergence of Devil Facial Tumour Disease. The study, published today in the journal Biology letters, involves Environment Institute member Jeremy Austin from the Australian Centre […]

A new measure for species extinction threat.

A new index has been developed to help conservationists better understand how close species are to extinction. The index, developed by a team of Australian researchers from the University of Adelaide and James Cook University, is called SAFE (Species Ability to Forestall Extinction). The SAFE index builds on previous studies into the minimum population sizes […]
