Use of cartographic method in studies of area penetration by mammals
Polska Akademia Nauk. Komitet Ekologiczny
This is a suggestion (to use an isorithm method the applied in cartography for determining the distribution and intensity of area penetration by mammals. Initial data on area penetration have been obtained using the technique of winter tracking. The whole area has been covered with assessment lines. During the assessment the number of tracks crossed by investigator was counted and identified to species. The results were unified by introducing an index of penetration intensity {number of tracks per 1000 m of .the route per 24 hrs). The index value was appointed to the middle of assessment line as the so-called empirical point. Between the points the isorithms were plotted. Thus maps of penetration by each species were obtained, which illustrated the spatial distribution and in tensity of its penetration. These maps can be compared with a topographical base (Fig. 1). Also these maps can be used in studies of habitat selectivity of animals (Fig. 2), seasonal variability of their penetration (Figs. 3, 4) and in analyses of interspecific relationships. The accuracy of estimated penetration discussed and it is indicated that it depends on the length of the assessment lines (Fig. 5) and the frequency of measurements on each line.
