Logging and slash-and-burn agriculture have dramatically altered Madagascar’s forests, but just how much of the island was forested before people got there remains a matter of debate. An analysis of mouse lemur DNA suggests that humans did not arrive to find Madagascar as tree-covered as frequently assumed.
Researchers from Duke University and UNC-Chapel Hill are testing the ability of drones to detect sharks in coastal waterways. Drones could eventually help alert swimmers to the presence of a shark, as well as track and study sea turtles, seals, and other marine animals.
Humans aren’t alone in their ability to mix perfumes and colognes. Lemurs, too, get more out of their smelly secretions by combining fragrances to create richer, longer-lasting scents, finds a study led by Duke University.
Allowing underwater seismic surveys for oil and gas to be conducted off the U.S. Mid-Atlantic and Southeast coasts could pose a substantial threat to one of the world’s most critically endangered whale species, a group of leading marine scientists say.
Habitat mapping software and satellite imagery can help conservationists predict the movements of endangered species in remote or inaccessible regions and pinpoint areas where conservation efforts should be prioritized, a new Duke University-led case study shows.
