Despite Stereotypes, Male Lions Actually Do A Little Work After All
2013-03-18 19:54:47

Lee Rannals for redOrbit.com — Your Universe Online As lazy as they may come off on nature channels, male lions actually are hunters and are quite successful at it, according to a new study published in Animal Behavior. Female lions are known for their hunting ability and have been observed by scientists to rely on cooperative strategies to tackle their prey. However, the latest research shows males are just as equipped to snag dinner. Authors of the paper wrote that male...

Study Finds People, Livestock And Carnivores Share Same Space
2013-03-14 08:40:53

Michigan State University In the southern Rift Valley of Kenya, the Maasai people, their livestock and a range of carnivores, including striped hyenas, spotted hyenas, lions and bat-eared foxes, are coexisting fairly happily according to a team of coupled human and natural systems researchers. “I wouldn´t call the results surprising,” said Meredith Evans Wagner, a visiting scholar from the University of Florida in the Center for Systems Integration and Sustainability...

Bite Size Determines Bite Force
2013-02-13 19:10:19

Brett Smith for redOrbit.com —  Your Universe Online Bite force allows animals to properly ingest food, making jaw mechanics very important -- especially for predators. A new study in the journal Biology Letters from biologists at Brown University has found an animal´s bite force depends upon the size of the thing the animal is eating. “Everybody measures bite force as one value,” said study co-author Nicholas Gidmark, a postdoctoral researcher at Brown....

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,...

Perceived risk of predation increased acceptance of immigrants into group Cichlid fish are more likely to accept immigrants into their group when they are under threat from predators and need reinforcements, new research shows. The researcher suggests that there are parallels between cooperatively breeding fish's and humans' regulation of immigrants. The research was published today, 6 February 2013, in the journal Proceedings of the Royal Society B. The Princess of Lake Tanganyika...

Trichomes Save Insect From Beetle Predation
2013-02-06 13:07:00

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...

Meerkats Climb To Hide From Predators
2013-02-05 18:13:09

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 —...

Grant’s gazelle (Nanger granti) is native to Africa. Its northern range of Tanzania extends south to Ethiopia and the Sudan, and from the coast of Kenya to Lake Victoria. It prefers habitats within shrub lands and grass plains, but can also be found in regions that are more arid. In Swahili, Grant’s gazelle is called Swala Granti. It was placed within the Nanger subgenus of the genus Gazella, before Nanger became a separate genus. Grant’s gazelle holds five recognized subspecies. The...
