Microbial and animal processing of detritus in a woodland stream

The detritus standing crop, microbial respiration, and macroinvertebrate biomass were examined in monthly samples from the riffle sections of a first-order woodland stream. Total detritus was remarkably constant; the average (with 95% CL) ash-free dry mass standing crop was 426.4 + 85.9 g/m^2 over t...

Description
Summary:The detritus standing crop, microbial respiration, and macroinvertebrate biomass were examined in monthly samples from the riffle sections of a first-order woodland stream. Total detritus was remarkably constant; the average (with 95% CL) ash-free dry mass standing crop was 426.4 + 85.9 g/m^2 over the 14 mo of the study. Throughout the year benthic detritus was dominated by fine particulate detritus (
