Leopard meals: Females go for diversity

Leopards, top predators of the African savannah, are known to feed on a variety of prey species. These include smaller and medium-sized mammals such as impala, gemsbok, kudus and warthogs but they can also target relatively small "appetizers" such as hares.

It has been largely unknown, however, whether they specialise in certain prey animals and which...

Migratory animals carry more parasites

Every year, billions of animals migrate across the globe, carrying parasites with them and encountering parasites through their travels. Now, a team of researchers at the University of Georgia's Odum School of Ecology discovered that animals known to migrate long distances are infected by a greater number of parasite species than animals that do not...

Researchers find genetic 'dial' can control body size in pigs

Researchers from North Carolina State University have demonstrated a connection between the expression of the HMGA2 gene and body size in pigs. The work further demonstrates the gene's importance in body size regulation across mammalian species, and provides a target for gene modification.

"Essentially, HMGA2 is a gene that controls the total number of cells that...

Alligators on the beach? Killer whales in rivers? Get used to it

Alligators on the beach. Killer whales in rivers. Mountain lions miles from the nearest mountain.

In recent years, sightings of large predators in places where conventional wisdom says they "shouldn't be" have increased, in large part because local populations, once hunted to near-extinction, are rebounding -- thanks to conservation.

Many observers have hypothesized that as these populations...

Could seismology equipment help to protect elephants from poachers?

Using tools developed to monitor earthquakes, an interdisciplinary team of researchers reporting in Current Biology on May 7 have found that it's possible to eavesdrop on elephants by listening in to vibrations through the ground as they move about and vocalize. The findings lend support to theories suggesting that elephants could use ground vibrations for...
