Cellulolytic Decomposition in Welsh Upland Rivers Following Leaf Addition

January and March 2013 data from an experiment measuring cellulolytic decomposition in eight Welsh upland rivers. The study, led by Dr Isabelle Durance and Dr Dan Perkins, examined responses to riparian deciduous leaf addition across moorland and conifer forest sites at Llyn Brianne and Plynlimon.

Use Cases

• Analyze cellulolytic decomposition rates before and after deciduous leaf addition to assess ecosystem response.
• Compare decomposition patterns between moorland and exotic conifer land-use types across the eight sampling reaches.
• Examine the relationship between aquatic biodiversity and litter decomposition using cotton strip assay data from the DURESS project.

Strengths

• Experimental design includes control reaches and treatment reaches with leaf addition for direct comparison.
• Data collected from eight distinct sampling reaches across two well-studied upland sites in Wales.
• Research conducted under the NERC-funded DURESS project with documented grant reference NE/J014818/1.

Limitations

• Limited temporal coverage with only two sampling points in early 2013, restricting analysis of seasonal or long-term trends.
• Geographic scope is restricted to eight river reaches in two Welsh upland areas, limiting generalizability.
• Sample size and specific metrics like row count or measured variables are not provided in the input.
