Fossils of a giant new species from the long-extinct group of sea creatures called trilobites have been found on Kangaroo Island, South Australia.
Giant petrels will be "temporary" winners from the effects of climate change in the Antarctic region - but males and females will benefit in very different ways, a new study shows.
When a male or female white-browed sparrow-weaver begins its song, its partner joins in at a certain time. They duet with each other by singing in turn and precisely in tune. A team led by researchers from the Max Planck Institute for Ornithology in Seewiesen used mobile transmitters to simultaneously record neural and acoustic signals from pairs of birds singing duets in their natural habitat.
New research published in the Journal of Natural History indicates that zebras' stripes are used to control body temperature after all - and reveals for the first time a new mechanism for how this may be achieved.
When it comes to making friends, it appears dolphins are just like us and form close friendships with other dolphins that have a common interest. The findings, published in the Proceedings of the Royal Society B by an international team of researchers from the Universities of Bristol, Zurich and Western Australia, provides further insight into the social habits of these remarkable animals.
Smalleye stingrays are the largest marine stingrays on record, reaching disc widths of up to 222 cm, and yet almost nothing is known about them. Scientists from the Marine Megafauna Foundation have for the first time used photo IDs to study this elusive animal in southern Mozambique, one of the only locations where it is regularly seen in the wild. Their findings are published today in the journal PeerJ.
The cooling of the Southern Ocean surrounding Antarctica, which began approximately 35 million years ago and gave rise to its present icy state, has for decades been considered a classic example of climate change triggering rapid adaptation.
The prime predators of the Baltic Sea at the top of the food web are losing weight, according to a new study that links the deteriorating health of gray seals and cod with changes in bottom-living crustaceans, isopods, and amphipods.
The winter ice on the surface of Antarctica's Weddell Sea occasionally forms an enormous hole. A hole that appeared in 2016 and 2017 drew intense curiosity from scientists and reporters. Though even bigger gaps had formed decades before, this was the first time oceanographers had a chance to truly monitor the unexpected gap in Antarctic winter sea ice.
Commercial fishers are acutely aware of the potential for marine litter to cause lasting damage to their catches and the wider industry, a new study suggests.
Two children's milk teeth buried deep in a remote archaeological site in northeastern Siberia have revealed a previously unknown group of people lived there during the last Ice Age.
Just about everybody loves peanut butter. We put it on sandwiches and in candy, we use it to trick our dogs into taking their heartworm pills, and, when we have to, we bait mouse traps with it. But, as scientists learned when trapping rodents in the mountains of the Philippines, peanut butter isn't for everyone. A highly distinctive (weird-looking) group of rodents sometimes called "tweezer-beaked hopping rats" don't care for peanut butter, but love earthworms. Armed with this knowledge (and worms), the scientists discovered two new species of the tweezer-beaked hopping rats. The discovery was announced in the Journal of Mammalogy.
The mineralocorticoid receptor (MR) regulates water and sodium transport throughout cells and tissues, which is critical for controlling blood pressure and so, not surprisingly, the MR is common to all vertebrate animals. Aldosterone, which is a physiological steroid for land vertebrate MRs, evolved in lungfish (forerunners of land vertebrates), suggesting that the evolution of aldosterone was important in the conquest of land by preventing dehydration in animals living out of water.
We've learned bees can understand zero and do basic math, and now a new study shows their tiny insect brains may be capable of connecting symbols to numbers.
Just like humans leave DNA in the places we inhabit, water-dwelling animals leave DNA behind in the water column. In a paper published June 3 in the journal Current Biology, scientists report that sponges, which can filter 10,000 liters of water daily, catch DNA in their tissues as they filter-feed. This proof-of-concept study identified fish, seal, and penguin DNA in sponges from the Antarctic and Mediterranean, demonstrating that sponges can be used to monitor biodiversity.
