Using GPS to remotely observe wildlife behavior
Mammals, Technology-GIS GPS plays an important role in wildlife conservation by enabling managers to track the movements of animals. But sometimes wildlife biologists want to know more than just where an animal is located at any given time - sometimes they also want to know what an animal is actually doing...
Popular herbicide can be a secret killer of fish
Fish, Freshwater The chemical glyphosate has emerged as the most widely used herbicide in the world. As a new study suggests, the popular herbicide may have unexpected negative impacts on fish by making them more vulnerable to disease...
Can biomanipulation of the sea rescue a collapsed fishery?
Fish, Marine, Restoration The cod stock in the Baltic Sea collapsed in the 1990s because of overfishing and climate change, and this once-valuable fishery has not yet recovered. Could intensified harvesting of sprat—a small fish that eats cod eggs and competes with young cod for planktonic food—be the solution to restore cod, as some people suggest?
Study finds post-restoration wetland succession highly variable
Restoration, Wetland A new study from researchers at the University of Illinois has looked at wetland restoration projects across the state and found that successional trends vary substantially from one site to another. The study findings have implications for the Clean Water Act and its ability to meet its mandate of enforcing no net-loss of wetland area or function in the United States...
When wildlife avoids perfectly good habitat: the perceptual trap
Birds What should we do when perfectly good habitat exists but certain species of wildlife decide to avoid it anyway? Researchers from the University of Oklahoma grapple with this potential mismatch between wildlife perception and habitat quality - a phenomenon they call the "Perceptual Trap."
