Professor Nicki Mitchell is one of Australia’s leading experts on how threatened wildlife can survive a rapidly changing climate. A zoologist and ecophysiologist, Nicki is a Professor in UWA’s School of Biological Sciences, Deputy Director of the UWA Oceans Institute and Lead Councillor of the Biodiversity Council.
For eight years, she served on Australia’s Commonwealth Threatened Species Scientific Committee, helping assess which species, ecological communities and threatening processes required recognition under national environmental law. Her pioneering research into assisted colonisation has attracted international attention, including coverage in Nature and The New York Times. She also leads a project believed to be the first in the world to trial moving a threatened vertebrate into new habitat specifically because of climate change.
In Episode 50 of Paramount Importance, Kurt Krispyn sits down with Nicki to explore a remarkable career spanning some of the world’s most unusual and vulnerable animals.
The conversation begins with the tuatara, New Zealand’s extraordinary reptile that can live for more than a century and represents the sole surviving lineage of an ancient group that once lived alongside the dinosaurs. Nicki explains how warmer nests produce males, why females in one isolated population reproduce only around once every nine years, and how climate change could push the population into an extinction vortex.
They explore how species are classified as threatened, what legal protection actually means and why many declining animals remain unlisted simply because scientists do not have enough data.
The conversation then turns to one of conservation’s most difficult questions. How far should humans intervene to prevent extinction? From cooling nests and incubating reptile eggs to moving entire populations towards safer climates, Nicki explains the science, risks and ethics of assisted colonisation. This includes her groundbreaking work trialling new habitats for the Critically Endangered Western Swamp Turtle.
Nicki also shares the remarkable beginning of her scientific career, researching a newly discovered Tasmanian moss frog whose enormous eggs develop inside moss for up to 14 months.
From tuatara and sea turtles to frogs, threatened species policy and world first conservation trials, this episode explores what saving wildlife may require when protecting its existing habitat is no longer enough.
