Pessimistic and optimistic bias in population viability analysis
Article Abstract:
Population viability analysis (PVA) is widely used for assessing extinction risk and exploring the consequences of potential management strategies. Its use in categorizing species as endangered and developing recovery targets requires that PVA output be quantitatively reliable, hence, it is important to know whether PVA predictions for population persistence are likely to be optimistic or pessimistic.

A framework for evaluating the effects of human factors on wildlife habitat: the case of giant pandas
Article Abstract:
Encouraging young people in the Wolong Nature Reserve in Sichuan Province to leave would have a greater impact on the panda population in the reserve than relocating older people. The number of humans in the reserve has increased since 1975 and the panda habitat has deteriorated.

The Interplay between Climate Variability and Density Dependence in the Population Viability of Chinook Salmon
Article Abstract:
Freshwater recruitment of Chinook salmon juveniles was related to spawner density, and broad-scale climate and ocean conditions were related to salmon third-year ocean survival rates. Data are analyzed and implications for Chinook recovery are discussed.
