摘要:
Rates of leaf litter processing were investigated in four Texas streams during fall-winter. Assuming an exponential decay model, processing coefficients (-k) of some leaf species were among the highest yet reported (e.g.Celtis laevigata= 0.0619). Values for % loss day−1ranged from 0.54–6.00. However, when compensated for the higher water temperatures found in these streams compared to more northern streams, processing rates were equivalent or even slightly lower. It is hypothesized that (on a per degree-day basis) this slower processing rate may result from the depauperate shredder fauna in such Texas streams.
