- Abstract
The article discusses a research study about the distribution of mitochondrial variation of the invasive North American beaver, Castor canadensis, across the archipelago of Isla Grade of Tierra del Fuego in Argentina. An Analysis the Molecular Variance (AMOVA) of beavers from three areas of the archipelago suggests the limit to gene glow among the beaver populations due to geographical barriers and large distances. A positive and significant autocorrelation between patterns of genetic affinity over short distances and the greatest haplotype diversity was also found in the subpopulation at the Tierra del Fuego National Park. This correlation is attributed to the control plan used in the park or by natural selection combined with diversity of habitat.
