JasmineLee 4 Adelie2 webCEED researchers Dr Justine Shaw and Dr Iadine Chadès are among a team of authors who have just published new research on the effect of climate change on biodiversity in Antarctica.

The paper titled 'Climate change drives expansion of Antarctic ice-free habitat' was released in the journal Nature this week. The research provides a prediction of the expansion of ice-free areas of Antarctica due to climate change, and was led by Justine's PhD student, Jasmine Lee.

The research suggests that Antarctica's ice-free habitat could expand by almost 25%, to a total area of 17,000 km2.

Most of this expansion is likely to occur in the Antarctic Peninsula, a location that scientists expect to experience the greatest degree of climate change by the end of the century.

An increase in ice-free habitat will have many and varied impacts on the local biodiversity - a system that includes Adelie penguins (pictured), many invertebrates, mosses, lichens and microbes. The researchers hypothesize that the effects could lead to the extinction of less-competitive species and the spread of invasive species.
