Geographical Distances

Climatic and species–environmental models for seven regions of Quebec boreal and boreal-transition forest were developed using principal components factor analysis. Climatic models based on growth-relevant meteorological parameters indicated that despite large geographical distances, all regions were very similar. The first principal component in the climatic model accounted for 73% of the total variation in the original climatic variables. Two regions were relatively dissimilar, coinciding with differences in predominant air mass during the growth season.Analytical models of tree species and tree species with environmental variables were based on 1668 forest plots. Compositional and environmental models were similar as were major ecological species–environment relationships among the seven regions. Air and moisture drainage related to catena, natural stand disturbances related to specific edaphic parameters, and microclimate related to slope aspect accounted for 29.7%, 21.5%, and 17.4% of the variance on first, second, and third principal components, respectively. Validity of the models and problems for further investigation are discussed.

Recently, we developed a numerical approach for the simulation of detonation waves on fully unstructured grids and applied it to the numerical study of the mechanisms of detonation initiation in multifocusing systems. Current work is devoted to further development of our numerical approach, namely, parallelization of the numerical scheme and introduction of more comprehensive detailed chemical kinetics scheme.

Successional Stages

The secondary birch and aspen forests of middle stages of succession of the central elevated part of the Southern Urals are studied. 4 subassociations, 1 community, and 7 variants in the alliances of Aconito-Piceion and Piceion excelsae are allocated. It is shown that the floristic composition of aspen and birch secondary forests in the age of 60—80 years is almost identical to the natural forests. However, a slight increase the coenotical role of light-requiring species of grasslands and hemiboreal forests in the secondary communities of the class Brachypodio-Betuletea was noticed as well as some reduction of role the shade-tolerant species of nemoral complex and species of boreal forests of the class Vaccinio-Piceetea. Dominant tree layer under the canopy of secondary series is marked by an active growth of natural tree species.
