Microsatellite analysis of population structure in the endangered Hawaiian monk seal

Article Abstract:

The population structure in the endangered Hawaiian monk seal, which breeds at six places in the Hawaiian Islands, has been subjected to microsatellite analysis to see whether significant genetic differentiation exists among the sites. Only at the microsatellite locus for which the sample size was the largest was the trend to genetic differentiation seen between the two subpopulations at extreme ends of the range significant. Moving seals has had positive demographic effects.

Functional ecosystems and biodiversity buzzwords

Article Abstract:

Accurate models of functional ecosystems can be obtained solely through focusing on nature's relationships between organisms and processes. Many contemporary theories of biodiversity are founded on abiotic factors that are separated from organismal data, producing vague or inaccurate information on species. Inefficient conservation policies are then derived from this flawed data.

Conservation genetics at the species boundary

Article Abstract:

The article makes a case for adapting conservation genetics in the classification and prioritization of populations to account for their phylogenetic relationships and heterozygosity. Data indicate that this character-based approach is superior to diagnostic methods in the implementation of conservation programs.
