2013 data measures algal production in eight Welsh upland rivers across moorland and conifer forest sites. The experiment compares four reaches with deciduous leaf addition against four control reaches, with samples collected before and after addition. Dr Isabelle Durance organized the surveys under the NERC-funded DURESS project.
Use Cases
- Analyze algal production response to deciduous leaf addition across eight sampling reaches.
- Compare algal biofilm metrics between moorland and exotic conifer land-use sites at Llyn Brianne and Plynlimon.
- Examine changes in aquatic biodiversity and organic matter stocks before (January) and after (March) leaf addition.
Strengths
- Data from eight distinct sampling reaches across two major Welsh upland sites.
- Experimental design includes four treatment and four control reaches for direct comparison.
- Temporal coverage includes measurements before and after the experimental leaf addition in 2013.
Limitations
- Sample size is limited to eight river reaches, restricting statistical power for broad generalization.
- Data is from a single year (2013), limiting analysis of inter-annual or long-term trends.
