Document Summary
Allee effects, demographic & environmental stochasticity, and genetic effects. Biologists hypothesized the availability of nest cavities were limiting. In particular, they hypothesized that clusters of cavities were needed as the woodpecker is a cooperative breeder. Artificially installed cavities proved important in the recovery strategy. Additional efforts included population viability analyses, genetic analyses, field studies, and political efforts. Conservation biology is an integrative discipline that applies the principles of ecology to the protection of biodiversity. Integrative approaches are characteristic of conservation biology the scientific study of phenomena that affect the maintenance, loss, and restoration of biodiversity.

The loss of one species can affect other species. Species introductions are increasing globally, leading to a growing taxonomic homogenization of earth"s biota. Primary threats to biodiversity include habitat loss, invasive species, overexploitation, pollution, disease, and climate change: habitat loss and degradation are by far the most important threats to biodiversity.
