TABLE 2.

Decomposition rates of alder leaves at four sites in the Ave River

Site	k (day−1)a	W0 (%)b	r2c	nd
L1	0.022 ± 0.0021a	97.7	0.85	20
L2	0.020 ± 0.0011a	99.0	0.94	24
L6	0.013 ± 0.0018b	87.4	0.70	24
L7	0.042 ± 0.0024c	104.3	0.93	24

^aValues are means ± SEM. Similar letters indicate no significant differences (P ≥ 0.05) between leaf decomposition rates (ANCOVA, Tukey's test).

^bW₀, initial AFDM of leaves.

^cr², coefficient of determination.

^dn, number of samples.
