The researchers say the global pattern of harvesting and decline of wild populations of frogs appears to be following the same path set by overexploitation of the seas and subsequent “chain reaction” of fisheries collapses around the world.
The researchers have called for mandatory certification of frog harvests to improve monitoring and help the development of sustainable harvest strategies.
University of Adelaide ecologist Associate Professor Corey Bradshaw says frogs legs are not just a French delicacy.
“Frogs legs are on the menu at school cafeterias in Europe, market stalls and dinner tables across Asia to high end restaurants throughout the world,” says Associate Professor Bradshaw, from the University’s School of Earth and Environmental Sciences and also employed as a Senior Scientist by the South Australian Research and Development Institute (SARDI).
“Amphibians are already the most threatened animal group yet assessed because of disease, habitat loss and climate change - man’s massive appetite for their legs is not helping.”
The annual global trade in frogs for human consumption has increased over the past 20 years with at least 200 million and maybe over 1 billion frogs consumed every year. Only a fraction of the total trade is assessed in world trade figures.
Indonesia is the largest exporter of frogs by far and its domestic market is 2-7 times that.
“The frogs’ legs global market has shifted from seasonal harvest for local consumption to year-round international trade,” says Associate Professor Bradshaw. “But harvesting seems to be following the same pattern for frogs as with marine fisheries - initial local collapses in Europe and North America followed by population declines in India and Bangladesh and now potentially in Indonesia.
“Absence of essential data to monitor and manage the wild harvest is a large concern.”
The study team also includes researchers from the Memorial University of Newfoundland in Canada, the National University of Singapore and Harvard University. A paper about the study is soon to be published online in the journal Conservation Biology.Media contact:

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
