Same-sized fish stick together, using chemical cues to identify each other Have you ever wondered why, and how, shoals of fish are comprised of fish of the same size? According to new research by Ashley Ward, from the University of Sydney in Australia, and Suzanne Currie, from Mount Allison University in Canada, fish can use a variety of different sensory cues to locate shoal-mates, but they are able to use chemical cues to find other fish of the same size as themselves. Using these cues,...

University of Guam Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator. The pest is called the cycad aulacaspis scale, and its invasion into numerous countries in recent years has caused immeasurable loss of biodiversity. Cycads belong to an ancient lineage of...

Brett Smith for redOrbit.com — Your Universe Online [ Watch the Video: Meerkat Predator-Scanning Behaviour Is Altruistic ] In studying the behaviors of animals, biologists are often looking to see if a species exhibits more individualistic or collectivist tendencies in their typical habits. When foraging for food, meerkats often stand on their hind legs or climb to a perch in an attempt to scan for predators and, upon spotting a threat, the animals let out a series of warning...

Prey Density Is More Important Than Total For Sea Predators
2013-01-04 13:02:20

Brett Smith for redOrbit.com - Your Universe Online As ocean predators comb the waters in search of a food source, they often seek out dense groups of prey to maximize their hunting efforts, according to a new study in the open access journal PLOS ONE. A team of American and Canadian biologists began their study by trying to find out where three different Bering Sea predators — northern fur seals and two different sea birds, black-legged kittiwakes and thick-billed murres —...

Brett Smith for redOrbit.com - Your Universe Online New research from a group of British scientists has provided a more detailed look into the selective diet of wolves living in northwestern Italy. Wolves are an apex predator across Europe and the new insights could translate into more informed conservation strategies for policymakers as well as better protective measures for the region´s livestock industry, which can be affected by wolf predation. According to the...

Light Pollution: How Does It Affect Wildlife Feeding Habits?

April Flowers for redOrbit.com - Your Universe Online Night-time satellite images of Earth show that every continent except Antarctica is ringed in a halo of brightly-lit human development, illustrating the fact that coasts and estuaries are among the most rapidly developing areas on the planet. Coasts are key wildlife sites as well. For example, every year millions of Arctic waterbirds arrive to winter on the UK coastlines. Scientists remain largely in the dark, however, about...

Eocene Bird Was A Giant But Peacuful Herbivore
2012-11-23 14:56:14

Brett Smith for redOrbit.com - Your Universe Online When scientists first discovered fossils of the Eocene bird Diatryma in the mid 19th century, they portrayed the 7-foot avian as a fierce predator, which caught on with science writers and popular culture. However, a recent discovery has suggested that this flightless giant was a gentle herbivore and not a flesh-eating terror as previously suggested. According to a report in the journal Paleontology, a set of 50...
