TABLE 2. Percentage contribution of bioclimatic indicators to the potential area of earthworm species. Climatic layers: 1—altitude above the sea level; 2—isothermality (average annual temperature / average daily temperature range for each month) * 100; 3—standard deviation of temperatures; 4—annual amplitude temperature (maximum temperature of the warmest month - minimum temperature of the coldest month of the year); 5—average temperature in the wettest quarter; 6—average temperature in the driest quarter; 7—amount of precipitation per year; 8—amount of precipitation in the driest month.
