However, analysis of elevational trends by years revealed two significant opposing linear trends for total, mycorrhizal and saprotrophic biomass; a decreasing trend in 2012 (slope total = −2.19 ± 0.95, P = 0.023; slope sapro = −0.89 ± 0.35, P = 0.013) and an increasing trend in 2013 (slope total = 3.48 ± 0.95, P < 0.001; slope sapro = 0.90 ± 0.35, P = 0.011).
