Historical and contemporary maternal population structuring in the endangered Hastings River mouse (Pseudomys oralis)
Article Abstract:
Historical and contemporary maternal population structuring has been studied in the Hastings River mouse (Pseudomys oralis) of Australia. The douse is and endangered conilurine rodent and only about 200 specimens have ever been caught. Little is known about the biology of the species. Temperature-gradient gel electrophoresis and DNA sequencing were used to study maternal population structuring and find out whether the pattern of fragmentation is anthropogenic. All sample localities were genetically distinct. One haplotype of 11 found was present in more than one sample locale. Contemporary population structure in the mouse has a historical component. Populations of the mouse are not only currently genetically isolated but have been so for a long time, evolutionarily. Each population should be considered to be demographically independent and managed separately.

Evaluation of the contribution of genetic research to the management of the endangered plant Zieria prostrata
Article Abstract:
The contribution of genetic research to management of the endangered coastal plant Zieria prostrata (Rutaceae) in Australia has been evaluated. A high level of population divergence was found for this plant that is known from four headlands on a 3-km strip of coastline and thought to have occurred 24 km south of the present range. Four management strategies are suggested by the genetic findings. For more effective conservation, the challenge is to identify cases for which genetic studies likely will bring about practical outcomes for conservation managers. Assessing outcomes of previous genetic studies is the best means to that end.

The Global 200: a representation approach to conserving the earth's most biologically valuable ecoregions
Article Abstract:
Strategies to conserve biological diversity should use ecoregional approaches. Research of biodiversity patterns can provide terrestrial boundaries, allowing conservationists to target an area's special needs. Dividing the continents into ecoregions also enables conservationists to assess existing damage and degradation to improve prioritization of environmental policies and programs.
