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.
Researchers at the University of Southampton have forecast a worldwide move towards smaller birds and mammals over the next 100 years.
Research carried out into the impact of changes to chimpanzee habitats found they have adapted to human developments in a number of ways - including learning how to cross roads safely and the best times to visit human habitats - but their survival is still threatened.
The evolutionary use of color for mammal's survival in the wild is evident from, red foxes, to zebras. Today an international team, led by researchers from The University of Manchester, published research revealing the evidence of colorful pigments from ancient mouse remains.
"This is the first time that we can show the impact of the mother's presence on a very important male fitness trait, which is their fertility," says Martin Surbeck, a primatologist at the Max Planck Institute for Evolutionary Anthropology. "We were surprised to see that the mothers have such a strong, direct influence on the number of grandchildren they get."
(Jena, Germany) Natural ecosystems are as vulnerable as they are diverse. Environmental changes such as climate change, pollution or the spread of alien species can easily throw an ecosystem off balance. Researchers are therefore investigating how susceptible ecosystems are to disruption. But in their search for answers, they face the problem that the complex network of relationships includes innumerable interactions, which are virtually impossible to record comprehensively and convert into measurable data.
Researchers reviewed the conservation priorities for the 31 species of tenrec - a poorly understood family of small mammals superficially resembling hedgehogs, found only on the island of Madagascar.
Conservation decisions based on population counts may fail to protect large, slow-breeding animals from irrevocable decline, according to new research coinciding with Endangered Species Day.
Bedbugs - some of the most unwanted human bed-mates - have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as dinosaurs.
Scientists have discovered a DNA mutation linked to breathing problems in popular dog breeds. Breathing difficulties are most often associated with flat-faced breeds, such as French bulldogs and pugs, but scientists have found the mutation is also carried by Norwich terriers, which have proportional noses.
The abundance of bird species living in agricultural environments has decreased both in Finland and elsewhere in Europe. Attempts to rectify the situation have been made with the help of agri-environment-climate subsidies. They are granted to agricultural producers by the EU for implementing measures that are presumed to be beneficial to the environment. There is a range of such subsidies, but their potential effects on biodiversity at national scales have been seldom comprehensively investigated.
Defaunation -- the loss of species or decline of animal populations -- is reaching even the most remote and pristine tropical forests. Within the tropics, only 20% of the remaining area is considered intact, where no logging or deforestation has been detected by remote sensing.
GAINESVILLE, Fla. --- The human environmental footprint is not only deep but old. Ancient traces of this footprint can be found in animal bones, shells, scales and antlers at archaeological sites. Together, these specimens tell the millennia-long story of how humans have hunted, domesticated and transported animals, altered landscapes and responded to environmental changes such as shifting temperatures and sea levels.
Wild pigs invade Canadian provinces--an emerging crisis for agriculture and the environment Wild pigs--a mix of wild boar and domestic swine--are spreading rapidly across Canada, threatening native species such as nesting birds, deer, agricultural crops, and farm livestock, research by the University of Saskatchewan (USask) shows.
