OCTOBER 2012: Dr Jean-Marc Hero and the Frogs of Fraser Island

Fraser's fabulous Wallum Sedge Frog Fraser's fabulous Wallum Sedge Frog

You'll find 18 different species of frog on Fraser Island - including the tree, sedge, rocket and southern frogs. Of special interest are four acid frogs - the Cooloola sedge frog, wallum rocket frog, wallum sedge frog (see main picture) and wallum froglet that have adapted to living in areas which have a low pH and high acidity level, as is found in most lakes and swamps of Fraser Island. 

The Cooloola sedge frog (Litoria cooloolensis) is a small, rare frog only known to occur on Fraser Island and in the Cooloola region in Queensland.  The wallum rocket frog (L.freycineti) is aptly named as it is able to jump distances of more than two metres. The copper-backed broodfrog (Pseudophryne raveni) and the wallum froglet (Crinia tinnule) are harder to find.

Dr Jean-Marc Hero is an ecologist and associate professor at Griffith University on the Gold Coast. His expertise in ecology stems from his extensive experience with amphibians, spanning over twenty years and across several continents.

Join Dr Hero as he unearths a wonderful world all about frogs at Kingfisher Bay Resort over the school holidays.

Topic: Global Amphibian Declines - over the past 30 years frogs have suffered massive declines and extinctions worldwide.  Declines are linked to habitat loss, fungal disease and climate change.

Dr. Hero has conducted fieldwork in Australia, Brazil, Fiji and Nepal. He has been on the forefront of global amphibian declines since they were first detected.  His current  research focuses on detecting the impacts of climate change on Australian frog species - stay tuned for Ranger Nick's frog blog or check out the frog blog archives!
