Earth Warming Shifts Ecosystems “With climate change, some species are winners, some are losers,” explains Walter Andriuzzi, the lead author of a two-decade-long study led by Colorado State University. The study has found that starting 2001, when a strange warm weather event occurred in the McMurdo Dry Valleys, the most common species in this desert […]

Drones aren’t just for the government. Research by the University of Exeter shows there are environmental applications for drones too. Now, with ‘point and shoot’ basic cameras, drones can improve understanding of dryland ecosystems at a reduced cost. The drylands are a critical provider of food, water, and biofuel with […]
