Effects of Genista aetnensis canopy on light regime.
Photosynthetic active radiation (PAR) attenuation along the vertical profile under (IN) and outside (OUT) the canopy of Genista aetnensis individuals at different ontogenetic stage (S1, S2, S3, D) at the Vesuvius Grand Cone. Data refer to mean and s.e.m. of PAR, expressed as percentage of the maximum recorded value (full light, 1171 μmol m2 s-1). See S8 Table for statistical analysis.
