Benthic organic matter of Welsh upland rivers in response to organic matter addition (2013)

These data are benthic organic matter stocks of coarse and fine particulate organic matter in eight Welsh upland rivers with contrasting land-use, moorland and exotic conifer, in response to riparian deciduous leaf addition. Eight sampling reaches were chosen at two sites, Llyn Brianne (4 reaches) and Plynlimon (4 reaches). The experiment consisted of adding deciduous leaves to half of the reaches whilst the other half were maintained as a control (no addition of deciduous leaves). To characterise the benthic organic matter of the studied streams, a Surber net was used to collect monthly samples during 2013 on January (before deciduous leaf addition) and from February to April (after deciduous leaf addition) in each sampling reach. The main goal of this survey was to examine how aquatic biodiversity and organic matter stocks respond to leaf addition in moorland and conifer forested rivers. Dr Isabelle Durance was responsible of organising the surveys, Marian Pye was in charge of collecting, processing and sorting the samples. The work was carried out under Diversity in Upland Rivers for Ecosystem Service Sustainability (DURESS) project (Grant reference NERC NE/J014818/1). DURESS was a project funded by the Natural Environment Research Council (NERC) Biodiversity and Ecosystem Service Sustainability (BESS) programme.

本研究数据集收录了八条威尔士高原河流中粗粒和细粒有机物质的底栖有机质存量，这些河流在土地利用方面存在差异，包括草地和外来针叶林，并针对河岸落叶树叶片的增加进行了研究。在两个采样地点，布莱恩湖（4个采样段）和普林利蒙（4个采样段），共选取了八个采样段。实验包括将落叶树叶片添加到一半的采样段，而另一半则作为对照组（不添加落叶树叶片）。为表征所研究河流的底栖有机质，采用苏伯网在2013年1月（落叶树叶片添加前）以及从2月到4月（落叶树叶片添加后）每月对每个采样段进行采样。本次调查的主要目标是探讨在草地和针叶林河流中，水生生物多样性和有机质存量如何响应落叶树叶片的增加。伊莎贝尔·达伦博士负责组织调查，玛丽安·派负责采样、处理和分类。该研究在“高原河流生态系统服务可持续性多样性”（DURESS）项目（资助编号NERC NE/J014818/1）下进行。DURESS是由自然环境研究委员会（NERC）的生物多样性和生态系统服务可持续性（BESS）计划资助的项目。关于该数据集的详细信息，请参阅https://doi.org/10.5285/32eaf811-be10-40cb-9794-7c5a1b97a915。
