What is the connection between virus prevalence and animal populations?
ch4aika [34]

Rinderpest disease is caused by a virus that affects hoofed animals, including cattle and wildebeest.

The figure shows the number of wildebeest in the Serengeti ecosystem (shaded circles, left y-axis) and the prevalence (i.e., percentage) of individuals infected by rinderpest disease (unshaded squares and triangles, right y-axis) from 1958 to 2003.
