2015 | Jessica Lynch Alfaro, et.al – Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin and rapid pan-Amazonian diversification of a lowland primate

ISG faculty, Dr. Jessica Lynch Alfaro, Dr. Michael E. Alfaro, et al, have published a paper titled “Biogeography of squirrel monkeys (genus Saimiri): South-central Amazon origin and rapid pan-Amazonian diversification of a lowland primate” in Molecular Phylogenetics and Evolution. Abstract: The squirrel monkey, Saimiri, is a pan-Amazonian Pleistocene radiation. We use statistical phylogeographic methods to create a mitochondrial DNA-based timetree for 118…

Endangered Monkeys in the Amazon Are More Diverse Than Previously Thought, UCLA Study Finds

Research by UCLA life scientists and 50 colleagues sheds new light on the biological differences among more than 150 species of monkeys in South America, many of which are endangered. Their findings could be particularly important in shaping efforts to conserve the biodiversity of primates in South America. The scientists have resolved a dispute over whether a small population of…

Mapping Human Disease: ‘Not All Pathogens Are Everywhere’

Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur. The findings show that the world can be separated into seven regions for vectored human diseases – diseases that are spread by pests, like mosquito-borne malaria – and five regions for non-vectored diseases,…

Why Do Chimps Kill Each Other?

War—what is it good for? “Absolutely nothing” according to the refrain of a 1970 hit song. Many humans would agree with this sentiment. But a major new study of warfare in chimpanzees finds that lethal aggression can be evolutionarily beneficial in that species, rewarding the winners with food, mates, and the opportunity to pass along their genes. The findings run…
