Fisheries researchers at Tennessee Tech University in Cookeville, Tenn., found one piece of a scientific puzzle that just may help save the endangered pallid sturgeon from extinction.
Two compounds emitted by mosquito predators that make the mosquitoes less inclined to lay eggs in pools of water may provide new environmentally friendly tactics for repelling and controlling disease-carrying insects.
In a pioneering use of computed tomography (CT) scans, scientists at Woods Hole Oceanographic Institution (WHOI) have discovered that carbon dioxide (CO2)-induced global warming is in the process of killing off a major coral species in the Red Sea.
A Cornell Lab of Ornithology team working in the Gulf has documented what may be the worst oil spill devastation of a major bird colony in the Gulf so far, on Louisiana's Raccoon Island.
In a report just published in Ecology Letters, wildlife ecologists from Michigan Technological University identify a link between malnutrition early in a moose's life and development of osteoarthritis as the animal ages.
As oil washes ashore along the Gulf Coast, the Cornell Lab of Ornithology is asking birders to keep an eye on nesting birds – not just near water, but hundreds of miles inland.
Iowa State University researcher Diane Debinski has been studying the meadows in the Greater Yellowstone Ecosystem of the Rocky Mountains since 1992 and she believes changing climate could affect the diversity of plants and animals in the region.
Scientific evidence presented indicates top-down regulation by predators operates in most ecosystems.
Deer populations are declining in the southeastern United States, and coyotes may be contributing to this decline. Although cause-and-effect studies have not been conducted, the expansion of the coyote’s range and its increasing numbers have coincided with the decline in deer. Wildlife management policies, such as limiting hunting of deer or manipulating habitat to ensure greater fawn survival, may therefore need to be adjusted.
Female zebra finches make one-note, low-pitch calls. Males sing over a wide range of frequencies. University of Utah scientists discovered how: The males’ stronger vocal muscles, not the pressure of air flowing through their lungs, lets them vary their pitch.
Inspired by the ease with which gecko lizards can move on almost any surface, researchers at Northeastern University, the Korea Institute of Science and Technology and Seoul National University hope to reproduce properties found in the gecko’s footpad for applications ranging from adhesives to robotic movement and navigation.
The aroma of rotting flesh may not permeate Western Illinois University's Botany Greenhouse today. But, hopefully, it will either Tuesday or Wednesday of this week. WIU's second Titan Arum (known as Titan #3) -- a plant that is also known as the "Corpse Flower," due to its pungent smell once it blooms -- has begun the blooming process, and Greenhouse Manager/Gardner II Jeff Hillyer was hoping that Titan #3 would bloom this afternoon (Monday). But based on his experience with WIU's Titan #1 (which bloomed in May), he is confident it will bloom sometime this week.
A wildlife ecotoxicology reference book co-edited by Texas Tech researchers is projected to become a national and international bestseller, according to the book’s publishers.
A new study in PNAS is believed to be the first to show experimentally that competition could be a factor in regulating ecological communities regardless of the intensity or frequency of disturbance.
People who fish for a living pursue top profits, not necessarily top predators, according to the first-ever analysis of worldwide catch and economic data for the past 55 years. This differs from the observation raised 10 years ago that humans were “fishing down” the food web.
Burn, grow, graze, and repeat. This is a formula that integrates fire and grazing strategies to restore grass to rangelands in the southern plains of the United States. Throughout the world, woody plants are showing an increased presence in grasslands and savannas, reducing the amount of grasses to sustain livestock and altering wildlife habitat and biodiversity. In the U.S. Great Plains, honey mesquite has encroached upon native grasslands to impact cattle grazing strategies and necessitate development of plant control efforts.
The nations of East and Central Africa have developed a 10-year action plan to save the eastern chimpanzee from hunting, habitat loss, disease, and other threats, according to an announcement made today by the Wildlife Conservation Society (WCS) and the International Union for Conservation of Nature (IUCN).
Canines trained in Auburn University's EcoDog program can help locate endangered species by identifying their specific excrement, or scat.
Jaguars versus cattle is an age-old conflict for people living on the Brazilian plains. South America’s Pantanal region is important to the continued survival of jaguars, but it also has been home to cattle ranching for more than 200 years. New insights into this conflict are offered through a study using global positioning system (GPS) technology to track the predatory patterns of these jaguars, recording what animals they kill and how often.
Insects may have tiny brains the size of a pinhead, but the latest research from the University of Adelaide shows just how clever they really are.
