The potential of discriminant analysis for assessing the parameters of an ecological niche is demonstrated by a case study with the pine marten (Martes martes L., 1758) via analysis of the dependence of marten footprint presence on the relief and environmental characteristics represented by remote sensing data, as well as calculation of the probability of(More)
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(More)
The article proposes approaches to the use of multi-spectral remote information in basic research on the spatiotemporal organization of biogeocenotic cover with and without the use of ground field measurements. It is postulated that remote measurements reflect the biophysical condition of biogeocenotic cover defined by the absorption and conversion of solar(More)
A method is proposed for estimating the quality of animal habitats from field counts with positioning routes and tracks by means of GPS, multichannel Landsat data, digital elevation model, and discriminant analysis. The distribution of American and European minks is analyzed to demonstrate the principle of choosing an optimal method for analyzing the(More)
The diversity and structure of the herbaceous layer were monitored on a transect through mixed forests in the Malinskaya Biogeocenotic Station (Moscow oblast, Russia). The data obtained in 1987 and 1997 were compared. The parameters of species rank distribution, number of species, and entropy estimate of specie diversity only slightly changed during that(More)
Observations of the trail activity of martens, mountain hares, and red squirrels in winter along fixed routes in the Central Forest Reserve showed high variability and synchronism in time and space. A polynomial dependence of the trail activity and a correlation in the spatial distribution of the marten, mountain hare, and squirrel were detected. The(More)
