Thompson, D. J. and Willms, W. D. 2014. Effects of long-term protection from grazing on phenotypic expression in geographically separated mountain rough fescue populations. Can. J. Plant Sci. 94: 33–39. Whether or not long-term grazing or protection from grazing alters the genetic makeup of grass populations has been debated. Mountain rough fescue [(Festuca campestris (Rydb.)], which is highly sensitive to summer grazing, and becomes dominant in plant communities with long-term protection, was chosen to address this question. Plants from three geographic sites (Stavely in AB, Milroy in the Kootenay trench, BC and Goose Lake on the BC interior plateau) with divergent grazing histories were vegetatively propagated from tillers. Daughter plants were planted into two field nurseries (at Kamloops, BC, and Stavely, AB) and morphological measurements were taken in two field seasons post-establishment. Plants from all three populations were taller, flowered earlier, and were more productive at the Kamloops nursery site. Of the three geographic sources, plants from the Goose Lake site were most distinct with narrower leaves, later flowering, and greater yield. Plants with a long history of grazing had slightly shorter fertile tillers and leaves than plants with a history of long-term protection.

Rough Fescue

Mountain rough fescue (Festuca campestris Rydb.) is a tufted native grass in southern Alberta and British Columbia, Canada, and has attracted interest for use in reclamation. However, its seed is often available from only a few localized sources and may not be adapted for areas removed from the collection site. We conducted a study to determine the genetic variability among rough fescue populations to assess its potential adaptation. Thirty plants were collected from each of six populations and analyzed using Random Amplified Polymorphic DNA (RAPD). One population (Kamloops, BC) was separated by several mountain ranges from the five easterly Alberta populations.The Kamloops population was also separated from the Alberta populations by genetic distance in two clusters. Of the total genetic variation present in the data, 21% was found among populations while the remaining (79%) was found within populations. Nei’s genetic distances among populations were related to their geographical distances. Genetic differences among populations appeared to be caused primarily by differences in gene frequencies rather than rare genes. Also, genetic diversity appeared to increase from west to east suggesting that the more easterly populations had greater adaptation potential. We speculate that the more easterly populations are less likely to share genes since the prevailing winds are from the west. Germplasm from the more easterly populations may be used with suitable precautions within Alberta and possibly around Kamloops.

Rate and percentage of emergence of 19 native and cultivated herbaceous species were studied at the following soil temperature: 6°, 13°, 18°, and 24 °C. The soil temperatures were held uniformly constant, and emergence data at the end of 5 weeks from four replications in time were obtained. The rate of emergence of all species was greater at 18 °C. than at 6 °C., and of all but five species was greater at 24 °C. than at 18 °C.The percentage of emergence of barley, bromegrass, crested wheatgrass, mustard, oats, peas, spring wheat, and wild oats was not significantly affected by soil temperature. Beans, corn, sugar beets, and sunflowers showed significantly lower emergence percentages at 6 °C. than at the three higher soil temperatures. Alfalfa, creeping red fescue, winter wheat, orchardgrass, rough fescue, sweet clover, and flax emerged best at moderate soil temperatures.

A biosequence of soil profiles, ranging from Black through various stages of Dark Gray to Eluviated Dark Gray Chernozems and a Degraded Brown Wooded soil, is found under a sequence of vegetation ranging from rough fescue prairie (Festuca scabrella association) to encroaching poplar (Populus spp.) and fir trees (Pseudotsuga taxifolia (Poir.) Britt.) in the Porcupine Hills of southwestern Alberta. Samples were gathered to establish the differential physical and chemical changes that have occurred in the soils over an 80-year period.Increased eluviation accompanied a reduction in the percentage of exchangeable calcium but it remained the dominant exchangeable cation in all horizons. Most of the exchange capacity arises from the organic matter. The exchange sites are mainly pH-dependent. The changes in the organic matter, because of the encroachment of trees, are more strikingly evident than are the changes in the mineral matter.Infrared absorption spectra of electrodialyzed humic acids display a conspicuous change in spectral pattern between 2 500 and 1 800 cm−1. There are indications of increased acidity and increased aromaticity in the humic acids of the B horizon as eluviation progresses.
