Multiple abiotic and biotic drivers of long-term wood decomposition within and among species in semiarid inland dunes: a dual role for stem diameter

This is wood decomposition data conducted in an semiarid inland dune
including mass loss, initial wood traits and k values of combinations
between five diameter classes and four shrub species under
different treatments including UV and litter position. We found
that after 34 months of in situ incubation, the mass loss of buried woody
litters was three times faster than those of suspended and
surface woody litters (53.5 ± 2.7 %, 17.0 ± 1.0 % and 14.4± 1.2
%, respectively). In surface and suspended positions, litter
decomposition rates were almost equally low and most mass loss
was during the first two years, when bark was still attached and UV
radiation had no significant effect on woody litter mass loss.
