“…The second stage included supervised classification, where the supervised data are environmental variables including a set of multispectral reflectance and coefficients of the digital elevation model. The classification was performed using linear discriminant analysis (LDA) [84]. We used Landsat Level-2 Science Products including surface reflectance bands 1-7 and the spectral indices NDVI, EVI, MSAVI, SAVI, NDMI and NBR [85].…”

East European forests dominated by Norway spruce (Picea abies (L.) H. Karst.) in the broad-leaved–coniferous zone should be considered as secondary communities formed under the influence of centuries-long activities (logging, fires and planting) and extended outside their natural range. The study raises an issue—how stable is the current state of Norway spruce forests in the center of the Russian plain and what is the effect of silviculture on the forest cover of the large urban agglomeration—the Moscow Region? Current study is based on multidisciplinary research and consequently concerns the age dynamics of spruce plantation forests, the species and typological diversity of mature spruce forests and spatial pattern of spruce forests along the south edge of their range. The composition and structure of Norway spruce plantations have been studied for various age classes and compared with mature natural spruce forests and pine plantations on the basis of field data. Remote sensing data and modeling approach were applied to estimate the spatial structure of spruce forests. It is found that mature plantations (over 80 years) become similar to natural forests in terms of structure and composition. The relationship between the distribution of spruce formations and the climatic and geomorphological conditions are confirmed. The proportion of spruce and spruce–aspen/birch communities follows the pattern of zones—the transition from the coniferous and broad-leaved forest zone to the broad-leaved forest zone. Despite the significant anthropogenic impact and the high proportion of plantations in the composition of Norway spruce forests (about 60–80%), their floristic and typological diversities correspond to such properties of zonal broad-leaved–coniferous communities. Over-matured plantations can provide valuable habitats for the re-establishment of native typological diversity. This makes it possible to use silviculture stands as an accelerated alternative to the natural recovery of disturbed habitats.

“…Because of the different expected patterns of the effect of climate and relief on species distribution, the dimensionality is reduced for them separately. The methods for reducing dimension ality or determining the rank parameters in the context of a particular problem are described in several papers (Puzachenko, 2004;Krenke and Puzachenko, 2008). In this case, the most efficient is the principal compo nent method with space dimensionality determined based on the scree test with subsequent rotation of the obtained components (generalized variables).…”

“…The difference between Grinnellian and Hutchinso nian niches reduces to the fact that Hutchinson regarded the niche as an attribute of species rather than something determined by environment, as in the Grinnell model. It is as if the Grinnell model specifies the niche in an a priori manner, while the Hutchinson model implies its association only with individual spe cies (Puzachenko et al, 2010).…”

Quantitative analysis of "point" distribution areas of species is analyzed; this method interpolates species distribution to the whole territory based on its correlations with climatic and landscape variables. It is demonstrated that the application of standard statistical interpolation techniques is inappropriate. The new approach uses the interpolation of the species specific relations with environmental variables determined at individual points to the whole territory. The basic method for solving this problem is factor analysis. This study analyzed methods for quantifying species relations to particular climate and relief variables. Efficiency of this analysis is demonstrated by a case study of three brown frog species: Rana temporaria, R. arvalis, and R. amurensis.

Distribution models have been constructed for 36 species of small mammals from southeastern Transbaikalia. The initial data used for modeling are the distribution of environmental factors (climate data and remote sensing of the earth surface) in the set of localities where each of the species was caught. The spe cies distribution ranges are explainable by the distribution of environmental factors in 30 cases out of 36; 17 of them are explainable by only one or two environmental factors. As for the remaining six cases, it is likely that historical factors and interspecific competition have considerably influenced the current distribution. The modeling results for these six species make it possible to propose hypotheses about the reasons underlying the current distributions, which cannot be proposed without using such a modeling approach.
