Document Summary
Factors that make a preserve more likely to protect biodiversity: o. Bigger is better than smaller- more interior habitat, species area curve, island. Connected- increases gene flow, increased pop size, island biogeography, biogeography (extinction) metapopulations. Buffers- buffer zones are areas around landscape areas, more interior habitat, ecosystem stability, fewer invasive species. Landscape change- more niches, sustainable, anthropogenic biomes, fragmentation disturbance patterns. More national parks in western us rather than east. This is bc when we started thinking about these things the west coast was less populated so more protected. Yosemite on signed bill and another valley into national park. Richard nixon responsible for a lot of environmental acts. Needs of umbrella species reflect needs of environment ex) if protect wolf can protect many other species because needs large habitat and many other species to fee on to exist. Endangered species act o o o o o o. Us was first country to enact legislation to protect endangered species.
