4. For seven species of woody broad-leaved evergreens we excavated plants in a range of sizes in the understories of three forests in southern Spain (for six of the species n = 20 to 40; for the seventh n = 10). We determined allometries relating variables x and y (i.e. log y = α log x + β) with α calculated as the reduced major axis slope (16). For each allometry different species typically had the same slope with different intercepts; we calculated common slopes. 95% confidence intervals and R 2 values were determined as for least-squares regression (16). SLA scaled with M T α = -0.22 ± 0.024 ( R 2 = 0.66); shoot dry mass scaled with root dry mass α = 1.02 ± 0.078 ( R 2 = 0.83); M S scaled with M R α = 1.10 ± 0.085 ( R 2 = 0.83); M L scaled with M T α = 0.97± 0.052 ( R 2 = 0.92) (17).
