“…For both PGM-1 and PEP-2, the sites West of the Cascade mountains showed variation, while those East did not show the variation. His results are consistent with earlier results of Baccus et al (1983) for Montana. His study, which focused on C. e. scotticus and North American comparisons, covered a limited region including northern subspecies, C. e. roosevelti and the most western C. e. nelsoni.…”

The distinctiveness of each extant North American subspecies of C. elaphus (Linnaeus, 1758) was tested using craniometric data. To provide a context for interpretation of these data, the distinctiveness of North American C. elaphus from Eurasian C. elaphus was reassessed from existing data and conclusions tested. Morphometric variations in size, shape, and sexual dimorphism of adult crania were analyzed using combined male-female and independent male and female principal component analyses. North American subspecies do not represent natural biogeographic variation as earlier presumed. Posterior classification error was highest for subspecies, but was lowest for a set of 6 Operational Taxonomic Units that recognized C. elaphus-Olympic, C. elaphus-northern California and Oregon, C. elaphus-eastern Washington, C. elaphus-Rocky mountain and Cascade mountain, C. elaphus-Saskatchewan and Manitoba, and C. elaphus-centralCalifornia. Males and females differed in their sizes, shapes and affinities to other populations. Intracontinental differences in the kind and amount of sexual dimorphism reinforced the importance of measuring and contrasting male and female features in phylogeographic analyses. Use of existing nomenclature as a blind guide for comparative systematics and ecology and for conservation undermines the quality of research and conservation for C. elaphus in North America. Previous arguments for a single-species circumglobal cline do not take into account sexual dimorphism, behavior and reproduction. Major intercontinental differences do exist between clinal extremes in behavior, in cranial size and sexual dimorphism in addition to semilethal Fi hybridization. All suggest C. elaphus and North American Cervus are different species. Whether the transition is smooth, whether stepped transitions occur, and whether "canadensis" correctly represents the species' distribution need verification.

“…Genetic divergence between Scottish and American (C e canadensis Erxleben, 1777) red deer was examined by Dratch and Gyllensten (1985). Values of polymorphism and average heterozygosity estimated in all these studies are within the range generally observed in mammals (Baccus et al, 1983;Nevo et al, 1984). Population genetic studies in European red deer have also been carried out in Germany and Hungary in demes of the local form C e hippelaphus Erxleben, 1777 (Bergmann, 1976;Kleymann, 1976;Albert, 1984;Bergmann and Moser, 1985;Herzog, 1986;Kabai, 1987;Herzog, 1988a,b (Wagenknecht, 1986).…”

“…Fallow deer is not an arctic, a specialist or an endemic species, although its natural range has been dramatically restricted following the climatic changes during the last Pleistocene glaciation. It is a medium body size species and low genetic variability is not expected from this point of view, although the body size hypothesis (Selander and Kaufman, 1973) is not fully supported from data on Cervidae (Baccus et a!., 1983) and on mammals in general (Wooten and Smith, 1985).…”

Tissue and blood samples from 180 fallow deer (Dama dama L.) belonging to an Italian free-ranging population were studied for biochemical variability by means of cellulose acetate and polyacrylamide gel electrophoresis. The 51 putative genetic loci successfully resolved showed a very low level of variability (P = 0020, H = 0.006) in accordance with previously reported data on British and West German populations. That low biochemical polymorphism in European fallow deer populations is discussed taking into account the effects of natural bottlenecks and of domestication.
