A new field study of two rival ant species has shown that ant queens will willingly mate with males from the opposing group in order to quite literally serve as "sperm parasites," stealing potential female births. The result is an unusual bedroom arms race between these ants, where they develop new strategies to use tricked males or to escape a rival queen's lustful clutches.
Tropical coral, the iconic face of coral life everywhere, fuse together with the help of calcareous algae that grow on the crust of the unusual animals' dead branches. However, not every species of coral colonizes in this manner. A new study on cold-water corals has found that even unrelated species can fuse in a unique process that does not require the help of a third party, making for some beautiful combinations of shape and color.
Salamanders throughout Europe are getting sick from a deadly fungal disease, and it threatens to spread to the United States through the pet trade unless international efforts are taken to stop it in its tracks, scientists reported Thursday in the journal Science.
A remarkably rare and threatened North American songbird appears to have found a new home in an unlikely place: the sprawling "biological deserts" of commercial pine farms. Conservationists had been concerned that the Swainson's warbler would ever boast a stable and unthreatened population. Now, with this new discovery, things are looking positive for the first time in decades.
Grizzly bears are making a comeback in Yellowstone National Park, according to a recent assessment of the threatened beasts. And this recovery has a lot to do with the fact that fewer grizzlies are dying in and around the park. Now officials are even considering lifting protections for the hardy animal.
It's very unlikely that you will hear someone say "that guy is so plump! I bet he's a great swimmer." However, according to researchers from the NOAA, that's exactly what we should be saying for sea turtles.
A new frog species was discovered in New York City from a display of odd chorus calls, reports say.
Raorchestes chalazodes, a rare bush frog found in India, has developed the unique strategy of breeding and laying eggs in bamboo despite their extremely narrow openings, new research describes.
She may have perished some 39,000 years ago, but Yuka the baby woolly mammoth is still teaching us about this behemoth species, and our own ancestors, as the subject of a new public display in Moscow.
A band of hungry hogs has gone wild in a Florida county, wreaking havoc on homes and threatening to ruin Halloween for all those trick-or-treaters out and about on Friday.
The giant tortoise is an ancient and iconic species of reptile that specifically characterizes the Galapagos islands. However, thanks to shrinking habitats and the introduction of new species to the islands, the tortoise has remained a threatened species. Now researchers are saying that the species as a whole is finally on its way to a slow-and-steady recovery.
Even as US companies and agencies continue to turn away from the deadly pesticides that left local bee populations despondently low, a natural factor is still making recovery earned. Now researchers behind a new study say that they discovered a nature-made solution to this natural problem.
Looking for a hefty catch the next time you're out fishing? You might want to get to know the fish of your local lake first. It turns out that the personality of a fish has a lot to do with how likely you are to catch it.
Think you've racked up an impressive number of frequent flier miles? Are you the kind of person to travel at a moment's notice? Sorry, but you've got nothing on the banded stilt. A new study has observed how this remarkable desert-dwelling bird will travel well over a thousand miles at the drop of a hat just to chow down on some incredibly unpredictable prey.
In their first few hours of life, sea turtles must battle hungry predators and dangerous waters before reaching the safe haven of ocean currents. While scientists have had just a general idea of how these vulnerable babies navigate the open water, for the first time a team has used special nano-tags to track the sea turtles' swims in more detail.
