Appendix C. Nitrogen and phosphorus dynamics after 42 days of litter exposure in a stream.

Table C1. Leaf litter nitrogen and phosphorus nutrient dynamics (mean ± SD) after 42 days of exposure in coarse-mesh bags. Values are the quotient between nutrient concentration at days 42 and zero (after leaching) and represent positive (> 1) or negative (< 1) dynamics of nutrients. Values for mixtures refer to pooled data across all mixed litter-bags for the respective species.
