Giving credence to the saying, "While the cat's away, the mice will play," a new study indicates that pumas and medium-sized carnivores lie low when they sense the presence of humans, which frees up the landscape for rodents to forage more brazenly.
Young Australian eastern blue-tongue lizards (Tiliqua scincoides) are every bit as clever as adults, researchers have found.
Researchers from the National Museums of Kenya, University of Arkansas, University of Missouri and Duke University have announced the discovery of a tiny monkey that lived in Kenya 4.2 million years ago.
Many dinosaur species are known from scant remains, with some estimates suggesting 75% are known from five or fewer individuals. Auroraceratops rugosus was typical in this regard when it was named in 2005 based upon a single skull from the Gobi Desert in northwestern China. But that is no longer the case.
A new study led by Mitch Irwin and Karen Samonds of Northern Illinois University finds that degraded rainforest habitats are having an unhealthy impact on at least one species of Madagascar's treasured lemurs, the most endangered mammal group in the world.
Rising temperatures could mean no male loggerhead turtles hatch at a key breeding ground by the end of this century, new research suggests.
Scientists have known insects experience something like a pain since 2003, but new research published today from Associate Professor Greg Neely and colleagues at the University of Sydney proves for the first time that insects also experience chronic pain that lasts long after an initial injury has healed.
The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program.
A University of Otago-led study is heralding advances in our understanding of one of the most startling transformations in the natural world - the complete reversal of sex that occurs in about 500 species of fish.
Physically bound to a specific location, plants have to devise special ways to secure their supply of vital nutrients. Most plants have developed a root system for the nutrients they need in order to survive out of the soil. But what if nutrient-poor soils fail to provide the necessities of life? Carnivorous plants such as the Venus flytrap have found a way out of this dilemma.
With little cases of ethanol to preserve tissue samples for total genomic DNA analysis, a trio covered much ground in the mountains of Japan and Korea to elucidate the evolution of the scorpionfly. The rugged scientists set out to use molecular phylogenetic analysis to show that the "alpine" type of scorpionfly and "general" type must be different species. After all, the alpine type exhibit shorter wings than the general type, and alpine type females also have very dark and distinct markings on their wings.
Spotted owl populations are in decline all along the West Coast, and as climate change increases the risk of large and destructive wildfires in the region, these iconic animals face the real threat of losing even more of their forest habitat.
The last, large, isolated, healthy chlamydia-free population of koalas in Australia may have been identified on Kangaroo Island, said Morris Animal Foundation-funded researchers at the University of Adelaide.
When Jeff Weakley tweezed open a blister-like bulge on his foot, he was not expecting to find a piece of a tooth from a shark that bit him while he was surfing off Flagler Beach in 1994.
Brazil's leatherback turtles are making a "gentle recovery" after 30 years of conservation efforts, new research shows. Scientists studied nesting sites in the state of Espírito Santo in eastern Brazil - the only place in the south-west Atlantic where leatherbacks regularly nest.
