a: P < 0.05, b: P < 0.01, c: P < 0.001. The relationship of fungal abundance and richness to parameters derived from direct climate measurements (calculated from the relative humidity and temperature of the habitat), annual climate records from nearby weather stations, and site-specific factors. Values are coefficients of determination (r2) with the sign of the slope in parentheses. Direct weather parameters were analyzed using records for the growing season, March to October, 1999. | ||
