Loss of lemurs might endanger many of Madagascar's largest tree species

Widespread logging and hunting have endangered virtually all of Madagascar's 100-plus species of iconic lemurs, and a new study by Rice University ecologists illustrates how saving the animals may also be key to saving the island's largest trees.

"Forest loss is a huge problem in Madagascar right now, but our study suggests that just saving the...

Giant panda population research shows new challenges

Conservationists often work to save species without having long-term population data. That can present major challenges for the science of saving species, as this kind of information is critical for making informed conservation policy and management decisions. In a recently published study in the journal Conservation Letters, a team of scientists reports results of a...

Ancient Moroccan dental remains elucidate history of long-lost African fauna

The most well known is Arsinoitherium, an animal that looked much like a rhinoceros but was in fact more closely related to elephants, sea cows, and hyraxes. Now, researchers reporting...

The evolution of testes

The loss of anatomical features is a frequent evolutionary event. For example, humans and other great apes have lost their tail and whales have lost their legs. The most convincing evidence comes from the presence of vestiges in fossils. Unfortunately, the fossil record preserves predominantly vestiges of hard structures such as bones or teeth. Consequently,...
