In ecosystems around the world, the decline of large predators such as lions, wolves and cougars is changing the face of landscapes from the tropics to the Arctic. An analysis of 31 carnivore species shows how threats such as habitat loss, persecution by humans and reductions in prey combine to create global hotspots of carnivore decline.
The Vapor, built by Pulse Aerospace of Lakewood, Colorado, can fly as high as 15,000 feet and be flown autonomously or under the control of a ground-based pilot. In a trial run near Corvallis, Michael Wing used the unmanned aerial system to study imaging techniques in a search-and-rescue operation.
Kristin Jones’ research aims to discover whether intensive forestry practices, such as herbicide use, interfere with wrens’ habitat.
Lee Buckingam master’s student in the College of Forestry, created a program that simulates greenhouse operations.
About a million years ago in South Africa, a cave dweller used fire on purpose, and some charred bones at the site suggest it may have been for cooking.
“Compare that to getting that heat or fuel from a hydrocarbon, renewable only on a scale of many millennia. Both create jobs and cause environmental effects, and both are heavily subsidized. Where are those jobs most desired, where do environmental effects have the least impact and what subsidies are most reasonable? We can expect more to come on these questions as the research rolls in.”
