Caloplaca tominii New to North America

Caloplaca tominii Savicz occurs in Southwestern Yukon (Canada, Region of Kluane), beyond its previous known range (Central Asia, southern Norway, Greenland). The species is epigaeous, strongly basiphytic, xero- and heliophytic. It grows in communities belonging to the Toninion coeruleonigricantis. Its occurrence in the Yukon is allowed by a strongly continental local climate in connection with periglacial phenomena

Contributions to quantitative phytogeography of Sicily. III. Correlation between phytogeographical categories, elevation and environment-types

Data source: Centrai Databank of the ltalian flora and vegetation. Database: phanerogamic flora of Sicily; percents of species with similar distribution patterns, subdivided into 49 phytogeographical categories, in 23 elevation intervals of 100m each. Methods: Complete Linkage Clustering with Correlation Coefficient far the classification of categories and of elevation intervals; Concentration Analysis far the ordination. Results: species with similar distribution tend to be most frequent along given sections of the elevation gradient. The degree of correlation between phytogeographical categories and elevation has been quantified
