Sound changes the way rodents sense touch

Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another. A new...

Contact with monkeys and apes puts populations at risk

Animal diseases that infect humans are a major threat to human health, and diseases often spillover to humans from nonhuman primates. Now, researchers reporting in PLOS Neglected Tropical Diseases have carried out an extensive social sciences evaluation of how populations in Cameroon interact with nonhuman primates, pointing toward behaviors that could put people at risk...

Historical genomes reveal recent changes in genetic health of eastern gorillas

The critically endangered Grauer's gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. The results are now published...

Howler monkey study examines mechanisms of new species formation

A new University of Michigan study of interbreeding between two species of howler monkeys in Mexico is yielding insights into the forces that drive the evolution of new species.

How do new species emerge in nature? One common but overly simplified version of the story goes like this: A population of animals or plants becomes geographically...

Camera trap study reveals the hidden lives of island carnivores

Researchers placed 160 cameras on 19 of the 22 Apostle Islands in northern Wisconsin to see which carnivores were living there. After taking more than 200,000 photos over a period of three years, the team discovered that several mammalian predators are living on various islands in this remote archipelago in Lake Superior.

Reported in the journal...
