Population viability analysis (PVA) is a method used by conservation scientists for a range of purposes — including advancing conservation theory, planning, policy and management. PVAs are particularly important for assessing the risks of population extinction and for comparing alternative management options to protect species. The fact that so many PVAs are already available, for hundreds of species, offers an exciting opportunity for learning and especially for moving from...

April Flowers for redOrbit.com - Your Universe Online A new study led by researchers at the University of Adelaide concludes that humans alone may have been responsible for the extinction of Australia's iconic native predator, the Tasmanian Tiger (thylacine). The study, published in a recent issue of the Journal of Animal Ecology, used a new population modeling approach to contradict the widespread belief that disease must have been a factor in the thylacine's extinction. The Tasmanian...

Last year, the World Conservation Union reported an unprecedented decline in biodiversity, with nearly 16,000 species facing extinction. The biggest threat to most species is loss of habitat. And as habitat loss and degradation proceed nearly unabated, the need to accurately predict the population dynamics and extinction risk of potentially endangered species has never been greater. In a new study, John Drake tests models traditionally used to estimate the likelihood of extinction and shows...
