Reliability of relative predictions in population viability analysis

Article Abstract:

This article examines the veracity of the population viability analysis to make reliable predictions of the risks of extinction of biological species. Research indicates that the predicted changes in risks of decline within 100 years are more reliable than absolute predictions as shown by analyzing 10 years data. Results show that across 160 samples, the true and predicted risk are 0.59 and 0.89 for 10 and 100 years data, respectively.

A method for setting the size of plant conservation target areas

Article Abstract:

A set of concepts and formulas that can be used in lieu of detailed population viability studies and habitat modeling exercises to determine the protected areas required to provide desirable conservation outcomes for a suite of threatened plant species is outlined. The tools presented in the study provide a fast, transparent and explicit means of assessing the conservation requirements of plants.

The Consistency of Extinction Risk Classification Protocols

Article Abstract:

Three broadly used systematic conservation classification protocols are assessed for accuracy of extinction risk prediction, and causes of discrepancies are identified. Findings emphasize the importance adequate training and the representation of uncertainties in calculations and reports.
