Regional genetic structuring and evolutionary history of the impala Aepyceros melampus

Article Abstract:

Samples of 162 impala antelope (Aepyceros melampus) from throughout its distribution range in sub-Saharan Africa were surveyed using eight polymorphic microsatellite loci. It is suggested that the presence of such previously unknown regional structuring within the subspecies reflects a pattern of colonization from a formerly large panmictic population in southern Africa toward east Africa.

Biogeographic evidence for selection on mitochondrial DNA in North Pacific Walleye Pollock Theragra chalcogramma

Article Abstract:

Mitochondrial DNA variability among populations of Walleye Pollock, Theragra chalcogramma that extend around the rim of the North Pacific from the Sea of Japan to Puget Sound, Washington is discussed. It was seen that haplotype diversity varied from 0.70 in Puget Sound to 0.95 in the southeastern Bering Sea and was correlated with distance from Puget Sound.

Analysis of the complete human mtDNA genome: methodology and inferences for human evolution

Article Abstract:

A suitable methodology for determining the complete human mitochondrial sequence and the global mtDNA diversity in humans is described. The implications of the results with respect to the different hypotheses for the evolution of modern humans are discussed.
