Abstract The diversification of human induced disturbances upon natural ecosystems has contributed to wildlife habitat fragmentation which has been a serious threat to the survival of natural populations. Possible factors contributing to this decline include changes in food, loss of genetic variation, cover availability, evolution of predation, microclimatic effect, and lack of recolonization following extinctions. Habitat loss and fragmentation are processes that separate small populations,

Have you ever wondered what it would feel like to help out wild animals? This was exactly what I thought when I was a little kid.
