Comparison of functional and structural metrics associated with two types of decaying particulate organic matter in coarse mesh litter bags in stream. k = exponential decay rate.

  Plastic strips Alder leaf litter
k (day−1) 0.0010 0.0278
Leaching (%mass loss after 5 days in stream) 3.2 24
Cumulative respiration until 49 days (mgC) 15.0 127.0
Total abundance of macroinvertebrates 75 128
Shredders (%abundance) 28 (37%) 59 (46%)

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
