Mound architecture and season affect concentrations of CO<sub>2</sub>, CH<sub>4</sub> and N<sub>2</sub>O in nests of African fungus-growing termites
收藏资源简介：
Data includes concentrations (ppm/ppb) of CH<sub>4</sub>, CO<sub>2</sub> and N<sub>2</sub>O measured from a total of 132 samples originating from 30 different termite mounds from Taita-Taveta, Kenya. Gas samples were collected during three different field campaigns in 2019 and 2021. Gas concentrations were measured at the Mazingira Centre for Environmental Research and Education, International Livestock Research Institute (ILRI, Nairobi, Kenya) using an SRI 8610C gas chromatograph (SRI Instruments Europe GmbH, Bad Honnef, Germany) with two HayeSep D packed columns (3 m length, 1/8 in. diameter), one of which was connected to an electron-capture detector (ECD, temperature 350 °C) for N<sub>2</sub>O detection, and the other to a flame-ionization detector (FID, temperature 350 °C) for CO<sub>2</sub> and CH<sub>4</sub> detection.Data is linked to publicationVesala, R., Räsänen, M., Leitner, S., Mulat, D.

本数据集包含共计132份气体样品的检测数据，样品均采自肯尼亚泰塔塔韦塔（Taita-Taveta）地区的30个不同白蚁丘，检测指标为甲烷（CH₄）、二氧化碳（CO₂）及一氧化二氮（N₂O）的浓度，单位为ppm/ppb。气体样品于2019年与2021年开展的三次野外采样作业中采集。气体浓度检测工作于肯尼亚内罗毕国际家畜研究所（International Livestock Research Institute, ILRI）的马齐吉拉环境研究与教育中心完成，使用德国巴德洪讷夫SRI仪器欧洲有限公司（SRI Instruments Europe GmbH）生产的SRI 8610C气相色谱仪进行分析；该色谱配备两根HayeSep D填充柱（柱长3 m，内径1/8 in.），其中一根连接电子捕获检测器（electron-capture detector, ECD，工作温度350 ℃）用于一氧化二氮（N₂O）的检测，另一根连接火焰离子化检测器（flame-ionization detector, FID，工作温度350 ℃）用于二氧化碳（CO₂）与甲烷（CH₄）的检测。本数据集关联已发表论文：Vesala R, Räsänen M, Leitner S, Mulat DG, Mwangala L, Rikkinen J, Arppe L. 2023. 《蚁丘结构与季节对非洲培菌白蚁巢内CO₂、CH₄及N₂O浓度的影响》. 《生态昆虫学（Ecological Entomology）》, doi: 10.1111/een.13267.
