Vegetation Gradient

The relationships between the distribution of plant communities and environmental factors were studied in an open peatland – forest complex of the hypermaritime north coast of British Columbia. The entire vegetation gradient, from open through forested peatlands to upland forest, was primarily explained by slope and minimum level of groundwater table. Environmental conditions in the upland Tsuga–Rhytidiadelphus forest were considerably different from those of the other communities; differences were small among the Sphagnum open peatland, the Pinus–Sphagnum woodland, the Chamaecyparis–Fauria forest, and the Thuja–Gaultheria forest. Highest level of groundwater table, conductivity minimum, pH, and dissolved oxygen merely helped distinguish the upland Tsuga–Rhytidiadelphus forest from all other communities. The wet Thuja–Gaultheria forest could be more vulnerable than the upland Tsuga–Rhytidiadelphus forest to local hydrological changes caused by harvesting. Consecutive intraannual measurements of environmental variables are important in clarifying the relationships between distribution of plant communities and environmental variables, especially for communities with peat accumulation.

Major Mode

A study of angiosperm reproductive biology was made in four plant communities in southwestern British Columbia. Species of all four communities have staggered, peak flowering times, resulting in phenological spectra. Anemophily is the major mode of pollination in a salt marsh, while entomophily predominates in a subalpine meadow. Two sphagnum bogs have more of a balance between wind and insect pollination. There are corresponding differences in the proportions of showy-flowered species in the communities. It is proposed that interspecific competition has greatly influenced the evolution of both species and community flowering strategies.Biotic seed dispersal prevails in the salt marsh and bogs, while most of the subalpine meadow species are wind-dispersed. Species and community modes of dispersal depend on the nature of the vegetation and the relative availability of dispersal vectors, as well as on diaspore morphology.Although vegetative reproduction and self-compatibility are fairly common, the bulk of the flora and vegetation at all four sites has breeding systems promoting outcrossing. There is little evidence that the physical environments of these communities, all harsh in at least some respects, have selectively favored autogamous or agamospermous species.

Selected alpine plant communities of Lakeview Mountain in Cathedral Provincial Park of southern British Columbia were examined, as well as the corresponding abiotic factors of soils and microclimate. Multivariate analysis of percentage cover data revealed three major community types, dominated by Kobresia myosuroides (Vill.) Fiori, by Carex scirpoidea Michx., or by Carex scirpoidea and Carex capitata L. codominating. Abundant small-scale patterns in the form of significant associations between species were detected in all communities. Possible mechanisms generating these positive and negative associations are discussed and it is suggested that the species themselves, as well as abiotic factors, may be strong determinants of vegetation patterning. Species morphology, especially the root systems, may be the more important feature. The relative competitive abilities of these three major dominants may be a critical factor affecting the distribution of communities at the study site.
