(Eqn. 1)

where M_i and M_f are initial and final wood dry mass; when calculating the period-specific mass loss, M_i is the final wood dry mass of the previous stage and M_f is the final wood dry mass for this period.

The termite contribution decomposition was calculated as effect size (Borensteinet al. 2009) according to Eqn. 2, based on termite access and exclusion treatments described above.
