Austrаliаn quоlls hаve been the target оf majоr conservation efforts over the last few decades. Due to increasing development and habitat loss, their population has become fragmented into small reserves. This has resulted in these small, isolated populations becoming severely inbred. How does inbreeding threaten a population's health? [answer1] To counter the effects of habitat fragmentation, conservation biologists are developing corridors to allow individuals to move between these isolated populations. These corridors will promote [answer2], which will increase genetic variation and reduce inbreeding.
