Researchers predict painted turtles face extinction due to global warming
Research finds pirate perch probably use chemical camouflage to fool prey
(Phys.org) —It's a nocturnal aquatic predator that will eat anything that fits in its large mouth. Dark and sleek, it hides beneath the water waiting for prey. A Texas Tech University researcher says the ...
How flower density impacts bee visits
(Phys.org) —Ever wonder how the density of flowers in a patch influences the kinds of insects that visit it? Carla Essenberg, a former graduate student in the Department of Biology at the University of ...
Designer babies may explain insect sociality
(Phys.org)—Being able to choose the sex of their babies may be the key to the complex societies built by ants, bees, and wasps, according to Oxford University scientists.
Insect-eating bat outperforms nectar specialist as pollinator of cactus flowers
(Phys.org)—Of the two bat species known to visit the flowers of the cardon cactus in Baja California, one depends entirely on nectar and is highly specialized to feed from the flowers, which are adapted ...
Rapid changes in climate don't slow some lizards
(Phys.org)—One tropical lizard's tolerance to cold is stiffer than scientists had suspected.
Cutting Bergmann's Rule down to size
(Phys.org)—Matan Shelomi, a doctoral candidate in entomology at the University of California, Davis, is cutting Bergmann's Rule down to size.
Climate change may alter amphibian evolution
Most of the more than 6,000 species of frogs in the world lay their eggs in water. But many tropical frogs lay their eggs out of water. This behavior protects the eggs from aquatic predators, such as fish ...
Animals balance threat of starvation with threat of predators to stay alive
(Phys.org)—In the natural world, searching for food is a high-stakes game in which animals risk starving to death or being killed by a predator. New research from the University of Bristol shows that to ...
Baboon foraging choices depend on their habitat and social status: study
In a study published today in The American Naturalist, a group of scientists led by the Zoological Society of London (ZSL) have used a technique developed to study human consumer choices to investigate what i ...
Why do organisms build tissues they seemingly never use?
(Phys.org) -- Why, after millions of years of evolution, do organisms build structures that seemingly serve no purpose?
Predicting when plants face extinction threat
(Phys.org) -- Drawn to dense stands of wildflowers in search of food, bees and other pollinators carry pollen between plants and provide a vital service for the survival of many plant species.
Hinchinbrook gets its own frog
One species of frog has become three including one unique to Hinchinbrook Island following studies of their genetics and mating calls
For monogamous sparrows, it doesn't pay to stray (but they do it anyway)
It's quite common for a female song sparrow to stray from her breeding partner and mate with the male next door, but a new study shows that sleeping around can be costly.
Huge hamsters and pint-sized porcupines thrive on islands
From miniature elephants to monster mice, and even Hobbit-sized humans, size changes in island animals are well-known to science. Biologists have long believed that large animals evolving on islands tend to get smaller, while ...
