Present and future taxonomic selectivity in bird and mammal extinctions

Article Abstract:

Researchers in this study compared the distribution of bird and mammal species extinctions over the course of history across genera and families and investigated whether they occurred at random with respect to taxonomy. They found the distribution of extinctions and threat classification were mostly selective across genera and families. In addition, extinctions were clustered in taxa containing few species. Species in smaller genera had the higher probability of extinction.

Taxonomic stability and avian extinctions

Article Abstract:

The case of the endemic kite of the Cape Verde Islands, an archipelago 500 km west of Senegal, is discussed to illustrate a situation in which systematics is perceived as a threat to conservation and has become a serious threat to the preservation of species. The study shows that there is a real danger that administrators and conservationists will reject modern taxonomic revisions solely because the relevant taxonomic changes are viewed as impractical.

Translocation causes extinction of a local population of the freshwater shrimp Paratya australiensis

Article Abstract:

The effects of translocation on resident populations of freshwater shrimp are investigated. Results reveal that after 7 years, the resident population at one site becomes extinct due to mating preferences of both resident and translocated females for translocated males and crosses between resident females and translocated males being less viable as shown by allozymes and mitochondrial genes analysis.
