Urocitellus Richardsonii

Ancient DNA was extracted from 12 500 to 10 500 year old ground squirrel bones from Tse’K’wa, an archaeological site in the Peace River region of northeastern British Columbia, Canada. Analysis of mitochondrial DNA from seven individuals demonstrates that all are Urocitellus richardsonii (Richardson’s ground squirrel), a species not found in the region today. Phylogenetic and sequence analyses indicate these individuals share a previously undocumented mitochondrial control region haplotype that is most closely related to haplotypes observed in modern specimens from Saskatchewan and Montana. At the end of the Pleistocene these ground squirrels extended their range north and west into open vegetation communities that developed when ice sheets melted and glacial lakes drained. They were subsequently extirpated from the Peace River region when forests replaced earlier pioneering vegetation communities.

Production Areas

The hard-seed content of alfalfa (Medicago spp.) grown in Canada in relation to genotype and geographic location of production was surveyed for the commercial growing regions in Manitoba, Saskatchewan, Alberta and British Columbia. The average hard-seed content of all pedigreed production over a 5-yr period, ranged from 22 to 37% and that in nonpedigreed production was between 14 and 30%. A database of the five widely grown cultivars revealed that the hard-seed content of alfalfa in the most northerly growing areas in the Peace River region of Alberta and British Columbia ranged from 31 to 51%, while hard seed content of alfalfa produced elsewhere varied from 22 to 38%. There was no apparent effect of latitude on the proportion of hard seeds, while there was a small increase for two of the five cultivars in production areas further west. Of particular interest was the trend in viable seed production. There was consistent evidence suggesting that the proportion of viable seeds decreased in production areas further north, but increased in production areas further west. However, the minimum viability was always in excess of 85%. There was no correlation between hard and viable seed. Key words: Medicago spp., alfalfa, lucerne, hard seeds, viable seeds

Insular Populations

Mass collections of Picea sitchensis, and hybrids, extending from Haines, Alaska, to northern California have been studied with respect to morphology of the ovuliferous cones, twigs, and needles. The Pleistocene history of the species has been reviewed. A north–south gradient occurs in size of cone, length–width ratios of cone scales, sterigma angle, and phyllotaxy. The gradient is probably clinal and appears unaffected by the northerly three-fourths of the species range being in glaciated territory where Pleistocene survival, on nunataks, is suggested by the data. Collections along two sections of the Skeena River in British Columbia are interpreted as hybrid P. sitchensis × P. glauca populations backcrossed with the nearest one of the two parents, i.e., with P. sitchensis near the coast and P. glauca farther inland. Insular populations tend to show less variability in length–width ratios of the ovuliferous scales than do mainland populations.

The Cross

Jackson (Hordeum vulgare L.) is an early-maturing, hulled, six-row feed barley. It was developed at the Northern Agriculture Research Centre, Beaverlodge, Alberta from the cross BT607/Pomo. It is short in height, moderately strong strawed, and adapted to western Alberta and the Peace River region of British Columbia. Key words:Hordeum vulgare, barley, early maturity, cultivar description
