Many birds and mammals are socially monogamous — males and females pair up, live together, and often raise their young together. However, once methods for genetic paternity testing were introduced, it became clear that a great many socially monogamous animals are sexually unfaithful. In pair-living species, genetic monogamy is rare. In a new study, scientists report that coppery titi monkeys living in the Amazon lowland rainforest appear to be an exception. Researchers from the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen could not find evidence for extra-pair paternity in their study population in Peru.

The slow loris seems adorable. But its puppy-dog eyes and charming face mask belie its wild nature: These primates can be positively pugnacious, defending territories and offspring with venomous — and sometimes fatal — bites.

The world’s most critically endangered primate, the Hainan gibbon, is hanging on by a thread. The last surviving population is restricted to a single patch of forest on Hainan Island, China. So when a landslide created a large gap in the canopy of the gibbons’ forest habitat, scientists took action and built them a bridge. Now, they report the results of this conservation intervention. The findings suggest that ‘bridging the gap’ can be a simple and effective way of giving wildlife a helping hand.

At Mozambique’s Gorongosa National Park, a bold experiment is playing out to rescue a wilderness on the brink — and demonstrate the powerful role that fear plays in healthy ecosystems.

A new film from NOVA and HHMI Tangled Bank Studios documents one of the most ambitious wildlife recovery projects ever: the reintroduction of African wild dogs into Gorongosa. The project could be a victory for conservation but it’s also an opportunity to test a hypothesis about the role of fear in nature.

Why do frogs have the biggest of eyes of any vertebrate in relation to body size? How does eye size relate to a frog's lifestyle? Scientists are starting to uncover the answers.
