Dynamic biogeography and conservation of endangered species

Article Abstract:

Most species persist in the periphery of their historical geographical ranges, according to an investigation of range contraction in 245 species from a wide range of taxonomic groups and geographical regions. It seems that range contraction is highly influenced by anthropogenic extinction forces which make historical density patterns irrelevant. Areas along the range periphery and on remote islands and mountain ranges frequently provide very useful opportunities for protecting endangered species.

Range collapse, re-introductions, and biogeographic guidelines for conservation

Article Abstract:

Recommendations based on an investigation of range collapse in endangered mammals are still sustained, despite disagreement from C.M. Wolf and colleagues. Wolf et al. failed to define 'core' and 'periphery,' thus making the geographic guidelines they propose for translocations difficult to evaluate. The previous study of range collapse identified a tendency for endangered mammals to persist on the periphery rather than in the core of their historic range.

Low-coverage vaccination strategies for the conservation of endangered species

Article Abstract:

The effectiveness of vaccination strategy to conserve populations of Ethiopian wolves (Canis simensis) threatened by outbreaks of rabies, a fatal viral disease of mammals is reviewed. The study results show that vaccination used to enhance metapopulation persistence through elimination of the largest outbreaks of disease requires lower coverage than the conventional objective of reducing the reproduction number of an infectious agent to less than one.
