Extent of the degradation of biodegradable plastic strips enclosed in coarse or fine mesh litter-bags and allowed to decompose for 77 days in a stream or in the adjacent riparian zone. R = mean proportion of litter mass remaining relative to initial mass. SE = standard error. Superscript letters depict statistically different groups of samples (see Results).
|Stream − coarse mesh||0.95a||0.01|
|Stream − fine mesh||0.96a||0.00|
|Riparian − coarse mesh||1.02b||0.01|
|Riparian − fine mesh||0.97a||0.01|
