High spatial resolution seasonal distributions of faecally-derived waterborne and sediment bacteria in standing waters, Glasgow, UK, 2016-2017

This dataset contains information about water quality based on faecal indicators at 15 lakes in the Greater Glasgow conurbation, Scotland. Lakes were sampled in winter (2016/17) and summer (2017) with faecal indicators being quantified at high spatial resolution (up to 60 points per lake depending on water body size) in sediment and water from each lake. Faecal indicators were quantified based on standard dilution, membrane filtration and incubation for water, and incubation in bacteria-specific broth, followed by plating and incubation for sediment extracts. Contextual information about water quality, water bird densities, and land cover in different buffer sizes is also provided for each lake. The data were collected to investigate how connectivity and stressors interact to determine biodiversity and ecosystem function in freshwaters.

The work was supported by the Natural Environment Research Council grant NE/N006437/1 (Hydroscape: connectivity x stressor interactions in freshwater habitats)

本数据集涵盖苏格兰大格拉斯哥都会区15处湖泊基于粪便指示菌的水质相关数据。研究于2016/2017年冬季与2017年夏季对各湖泊开展采样，针对每处湖泊的水体与沉积物，以高空间分辨率（依水体规模最多可设60个采样点）完成粪便指示菌的定量检测。其中，水体样本的粪便指示菌定量采用标准稀释、膜过滤与培养流程；沉积物提取物则先置于细菌特异性肉汤中培养，再经涂布平板与后续培养步骤完成定量。此外，数据集还提供了各湖泊的水质、水鸟密度及不同缓冲尺度下的土地覆被等关联背景信息。本次数据采集的核心目标为探究连通性与环境压力因子如何相互作用，进而决定淡水生态系统的生物多样性与生态系统功能。本研究由自然环境研究委员会资助，资助编号为NE/N006437/1，项目名称为“Hydroscape：淡水生境的连通性×压力因子相互作用”。
