Climate change threatens Marine Protected Areas

New research from the University of North Carolina at Chapel Hill and collaborators found that most marine life in Marine Protected Areas will not be able to tolerate warming ocean temperatures caused by greenhouse gas emissions. Marine Protected Areas have been established as a haven to protect threatened marine life, like polar bears, penguins and...

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...
