A monkey’s life is full of stress: pressures from a disease and the lack of good food and their effects on abundance

Despite strong links between patterns that individuals deal with others and their success at breeding that ultimately affect the size of animal populations, the particular social and ecological factors that lead to endangerment are not well understood.

Do the costs and benefits of group living in a proportional manner with group size

Identifying the ecological and social factors that underlie vertebrate group size and social organization has been a question that has intrigued biologists for decades. This interest stems from the enormous variability in group size found both within

Archaeological surprise! Lucy has company

One of the most remarkable discoveries in the human fossil record is an Australopithecus afarensis partial skeleton nicknamed Lucy dated to 3.2 million years before present. Discovered in 1974 by Donald Johanson and his colleagues, the skeleton

Which regions of the skull contain the most information about genetic relatedness in monkeys?

The primate fossil record is plagued by issues with assessing phylogeny (genetic relationships among species) due to the fact that fossilized specimens are composed entirely of rock and contain no DNA. Paleontologists studying the primate fossil record

Infections in wild primates

Some of the most common parasitic infections in wildlife are caused by intestinal worms. Unlike bacterial or viral infections, however, worm infections rarely lead to death, and may not even cause overt clinical symptoms. In this research,
