How Australia got the hump with one million feral camels

A new study by a University of Exeter researcher has shed light on how an estimated one million-strong population of wild camels thriving in Australia’s remote outback have become reviled as pests and culled on a large scale.

Sarah Crowley, of the Environment and Sustainability Institute at the University of Exeter’s Penryn Campus, explored the history of the camel in Australia, from their historic role helping to create the country’s infrastructure through to their current status as unwelcome “invader.”

The deserts of the Australian outback are a notoriously inhospitable environment where few species can survive. But the dromedary camel (Camelus dromedarius) prospers where others perish, eating 80% of native plant species and obtaining much of their water through ingesting this vegetation. (more…)

Satellite tracking identifies Atlantic Ocean risk zones for leatherback turtles

The last large populations of the leatherback turtle are at risk because their migratory routes in the Atlantic Ocean clash with the locations of industrial fisheries, a new study shows.

Researchers used data from satellite transmitters attached to the turtles to track their movements across the Atlantic Ocean. These movements were then overlapped with information on high pressure fishing areas to identify where the turtles are most susceptible to becoming entangled and where they may drown. (more…)
