Another yellow fever case noted in Rio de Janeiro state

Most of the monkeys that have perished from yellow fever are brown howlers. This creates an interesting opportunity for the critically endangered muriqui monkeys, according to a UW-Madison news release. Muriquis are less susceptible to yellow fever. Researchers are studying if their population will thrive in the absence of howlers.”No one really knows the consequences for the other primates or the forest when nearly the entire population of an abundant species dies from disease in just a few months,” says Karen Strier, PhD, professor of anthropology.
