The role of behavior in recent avian extinctions and endangerments

Article Abstract:

Research suggests that several forms of behavior can impact a species' propensity for extinction or endangerment. In studies using recent avian extinctions, researchers found that endangerment or extinction propensity was affected by aggregation, dispersal, habitat selection, maladaptive behavior and interspecific responses. Prediction models should incorporate species behavior to improve their accuracy.

Rapid extinction of mountain sheep populations revisited

Article Abstract:

Population numbers do not create a consistent method for predicting extinction probabilities. In studies on mountain sheep, certain populations that were expected to disappear within 50 years have either maintained themselves or have expanded. This indicates that other factors in addition to numbers influence the ability of a population to survive or become extinct.

Will observation error and biases ruin the use of simple extinction models?

Article Abstract:

Results show that neither moderate levels of random observational errors nor sampling biases influence extinction risk estimates of the time series employed in conservation methods.
