None of the accidental movements are plotted in Figure 3. Factors Influencing Distribution The distribution of C. v. viridis in Canada corresponds very closely to the dry steppe climatic zone (Figure 2) and it may be that climate is the dominant limiting factor. But I believe that, at least locally, there are other important controls. In my opinion, the bedrock and surficial geology has always exerted con- siderable influence on the di

Groups varied in size from one to 137 plants and, typically, were composed of both clones and separate individu- als. More detailed information on distribution is recorded in Keddy (1979.

Moore (1966) concluded that the relative abundance of Mesoplodon bidens strandings on the European side of the Atlantic, in a gross way, was related to the greater abundance of animals living in that vicinity compared to the Western Atlantic. Saemundsson (1939) suggested the species has an open sea distribution with occasional visits to coastal waters.
