An ample buffet of freshwater food, brought on by climate change, is altering the life history of one of the world's most important salmon species.
The fear of invasive 'killer shrimps' can intimidate native organisms to such a degree that they are incapable of performing their vital role in river systems, a new study suggests.
New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds - changing how we look at dinosaurs, birds, and pterosaurs, the flying reptiles.
New Guinea is one of the only places in the world where frogs are safe from the species-destroying chytrid fungus. An international team of scientists has published a new paper that shows how to keep it that way, but they need help to carry out their plan.
The bigger the brain in relation to body size, the more intelligent a living organism is. This means that mammalian species with large brains are smarter than small-brained mammals. However, developing a large brain comes at a price: An infant expends around two-thirds of its energy alone on supplying nourishment to its brain.
The use of satellite telemetry in conservation is entering a "golden age," and is now being used to track the movements of individual animals at unprecedented scales.
Rickettsia bacteria cause a number of human and animal infections, including Rocky Mountain spotted fever. Now, researchers reporting in PLOS Neglected Tropical Diseases have for the first time surveyed the prevalence of Rickettsia antibodies and Rickettsia-carrying ticks in wild boars, hunting dogs and hunters in Brazil.
How did some marine fish manage to make their way from the salty sea to the newly available freshwater niches after the last ice age and eventually differentiate from their marine brethren?
EAST BOOTHBAY, Maine - New research connects recent changes in the movement of North Atlantic right whales to decreased food availability and rising temperatures in Gulf of Maine's deep waters. Right whales have been showing up in unexpected places in recent years, putting the endangered species at increased risk.
Elephant poaching rates in Africa have started to decline after reaching a peak in 2011, an international team of scientists has concluded.
An international team of scientists identified the snake and its range, which includes Turkey, Azerbaijan, Armenia, Georgia, Iraq, Iran, and Russia including a small region extending into the corner of Europe.
Scientists from the University of Bonn and the Sirindhorn Museum in Thailand have identified two new dinosaur species. They analyzed fossil finds that were already discovered 30 years ago in Thailand. Both species are distant relatives of T. rex, but with a somewhat more primitive structure. They were efficient predators. The results have now been published in the journal Acta Palaeontologica Polonica.
Wood-living beetles that use oak trees are a species-rich and threatened animal group in modern forestry and agriculture in southern Sweden. New research from the University of Gothenburg shows that management with conservation thinning can be an effective way to promote these beetles in the long term.
AMHERST, Mass. - Wildlife ecologists at the University of Massachusetts Amherst who are studying different conservation practices in the forests of Costa Rica recently made a startling discovery on a wildlife camera trap - wild bush dogs documented farther north than ever before and at the highest elevation.
Scientists from the University of Bristol and the Natural History Museum in London have reconstructed the evolutionary history of the chelicerates, the mega-diverse group of 110,000 arthropods that includes spiders, scorpions, mites and ticks.
