Document Summary
How can metapopulation structure a ect species richness overtime. Holes drilled through walls give hedgehogs little pathways from one garden to another. Female with kittens in san gabriel mountains typical home range is around 200 sq miles for adult males and 75 square miles for adult females.

Habitat island: an area habitat surrounded by di erent habitat. Clicker which hypothetical island would you expect to have the greatest number of species.
