Temporal patterns fits of epigeous sporocarps total annual biomass (kg ha−1) in P. sylvestris forest stands along an elevational gradient within a Mediterranean region (Catalonia): (A) total biomass, (B) square-root of saprotrophic biomass. Each point represent a sample plot. Continuous blue lines indicate significant temporal decreases or increases in richness (P < 0.05; GAMMs). Grey envelops are 95% confidence intervals.
