Urban Sprawl Threatens Animal Biodiversity
Federal Biologists just released a study linking sprawl and habitat fragmentation to genetic changes in populations of animals. The researchers studied four species – three types of lizards and one bird – in the Santa Monica mountains of California. Results showed the formation of “habitat islands,” which can cause in-breeding and decreased genetic diversity. In turn, the lack of genetic diversity threatens the species ability to adapt to a changing environment. Read more.
