Predictive accuracy of population viability analysis in conservation biology
Article Abstract:
Population viability analysis (PVA) can be seen as a valid and sufficiently accurate method for categorizing and managing endangered species. This research involved undertaking a retrospective test of PVA based on 21 long-term ecological studies. It was found that, given adequate data, PVA predictions are very accurate. These predictions should be valuable in the conservation contexts in which they are applied at present. There is convincing justification for the use of PVA for categorizing the vulnerability of endangered animal species and assessing options for their recovery.

Inbreeding leads to extinction
Article Abstract:
A new study provides clear evidence that inbreeding and loss of genetic diversity in the Glanville fritillary butterfly, Melitae cinxia, contribute to the extinction of wild populations. The topic has been much debated but this is the first hard evidence that inbreeding leads to extinction. It is clear that genetic factors must be taken into account when planning recovery strategies for endangered species.

Catastrophic extinctions follow deforestation in Singapore
Article Abstract:
A report on local extinctions among a wide range of terrestrial and freshwater taxa from Singapore (540 square kilometer) in relation to habitat loss exceeding 95 percent over 183 years is presented. The substantial rates of documented and inferred extinctions were found in greatest proportion of extinct taxa (34-87 percent) in butterflies, fish, birds and mammals.
