This suggests that vaccines administered to cattle reduced rinderpest transmission from cattle to wildebeest. Eradication of the virus allowed the wildebeest population to rebound from around 200,000 animals in 1958 to around 1,200,000 in the late 1970s. ... Both are examples of density-dependent population regulation.

What type of factor is rinderpest?

Rinderpest virus (RPV) is a paramyxovirus closely related to the human pathogen Measles virus. It causes severe disease in cattle, buffalo, and some wild animals; although it can infect humans, it does not cause disease.

What factors affect wildebeest population size?

KEY CONCEPTS A. Population sizes are affected by a variety of factors, including disease, resource availability, and human impacts.
