Mitochondrial phylogeography of moose (Alces alces): late pleistocene divergence and population expansion.

• Kris J. Hundertmark, Gerald F. Shields, Irina G Udina, R. Terry Bowyer, Alexei A Danilkin, Charles C. Schwartz
• Molecular phylogenetics and evolution
• 2002

We examined phylogeographic relationships of moose (Alces alces) worldwide to test the proposed existence of two geographic races and to infer the timing and extent of demographic processes… (More)

Phylogeography of brown bears (Ursus arctos) of Alaska and paraphyly within the Ursidae.

• Sandy L Talbot, Gerald F. Shields
• Molecular phylogenetics and evolution
• 1996

Complete nucleotide sequences of the mitochondrial cytochrome b, tRNA(prolime), and tRNA(threonine) genes were described for 166 brown bears (Ursus arctos) from 10 geographic regions of Alaska to… (More)

Calibration of mitochondrial DNA evolution in geese

• Gerald F. Shields, A. C. Wilson
• Journal of Molecular Evolution
• 1987

Mitochondrial DNA was purified from five American species of geese representing the generaAnser andBranta, which have fossil records. The results of electrophoretic comparisons of about 75 fragments… (More)

Lack of geographic structure in mitochondrial DNA sequences of Bering Sea walleye pollock, Theragra chalcogramma.

• Gerald F. Shields, J R Gust
• Molecular marine biology and biotechnology
• 1995

We compared 511 nucleotides of mitochondrial DNA from 162 walleye pollock from 32 locations in the Bering Sea, the Shelikof Strait, and the Gulf of Alaska to learn about population structuring in… (More)

mtDNA sequences suggest a recent evolutionary divergence for Beringian and northern North American populations.

• Gerald F. Shields, Alexander Schmiechen, +4 authors Ryk H Ward
• American journal of human genetics
• 1993

Conventional descriptions of the pattern and process of human entry into the New World from Asia are incomplete and controversial. In order to gain an evolutionary insight into this process, we have… (More)

Phylogenetics of the Caprinae based on cytochrome b sequence.

• P Colin Groves, Gerald F. Shields
• Molecular phylogenetics and evolution
• 1996

Relationships within the subfamily Caprinae have never been fully resolved. Phylogenies have been proposed based on morphological, behavioral, ecological, and some molecular comparisons. Because of… (More)

A phylogeny of the bears (Ursidae) inferred from complete sequences of three mitochondrial genes.

• Sandy L Talbot, Gerald F. Shields
• Molecular phylogenetics and evolution
• 1996

Complete sequences of DNA are described for the cytochrome b tRNA(Thr) and tRNA(Pro) genes of mitochondria of four extant species of ursids and compared to sequences of four other species of ursids… (More)

Sequence Characterization of a Unique Intergenic Spacer in Gadiformes Mitochondrial DNA

• Ingrid Bakke, Gerald F. Shields, Steinar Daae Johansen
• Marine Biotechnology
• 1999

The nucleotide sequences of intergenic spacers located between the tRNAThr and tRNAPro genes in mitochondrial DNA of cod fishes (order Godiformes) were determined. Spacers from eight species… (More)
