Calluna vulgaris root length and fungal colonisation data from the Climoor long-term climate change experiment in Clocaenog forest, UK (2015)

This dataset contains root length, biomass and fungal colonisation data for Calluna vulgaris from control, drought and warming treated soils from the long term climate change experiment in Clocaenog forest. Soil samples were collected from the climate change experiment in Northeast Wales during April 2015. Roots were separated from the soil, their length and biomass measured and then analysed using microscopy for Ericoid mycorrhizae (ErM) and dark septate endophyte (DSE) colonisation of Calluna vulgaris. The experimental field site consists of three untreated control plots, three plots where the plant canopy air is artificially warmed during night time hours and three plots where rainfall is excluded from the plots at least during the plants growing season (March to September). The Climoor field experiment intends to answer questions regarding the effects of warming and drought on ecosystem processes and has been running since 1999. The root length and fungal colonisation data aims to understand how changes in soil hydrological and chemical properties have influenced Calluna vulgaris rooting behaviour and interactions with the soil microbiome. This work was supported by the Natural Environment Research Council award number NE/R016429/1 as part of the UK-SCAPE programme delivering National Capability.

本数据集收录了从Clocaenog森林长期气候变化实验中获取的绒藜（Calluna vulgaris）的根长、生物量和真菌定殖数据，数据来源包括对照组、干旱处理组和升温处理组的土壤。土壤样本采集于2015年4月的东北威尔士气候变化实验。将植物根系从土壤中分离出来，测量其长度和生物量，并利用显微镜分析绒藜的根际菌根（Ericoid mycorrhizae，简称ErM）和暗隔内菌（Dark septate endophyte，简称DSE）的定殖情况。实验场地包括三个未处理的对照组、三个夜间人工增温的植物冠层处理组和三个在植物生长季节（3月至9月）至少排除降雨的处理组。Climoor野外实验旨在探讨升温与干旱对生态系统过程的影响，该实验自1999年开始运行。根长和真菌定殖数据旨在理解土壤水文和化学性质的变化如何影响绒藜的根系行为及其与土壤微生物组的相互作用。本研究得到自然环境研究委员会（Natural Environment Research Council）资助，项目编号为NE/R016429/1，属于英国-SCAPE计划，旨在提供国家能力。
