Data for: Wetland productivity determines trade-off between biodiversity and greenhouse gas production

The data consists of wetland nutrient, chlorophyll-a, methane and nitrous oxide concentrations, as well as emergence data of chironomid midges, and water temperatures. The data collection took place in 2021 in May, June, July, August and October, with simultaneous collection of chironomid emergence and water chemistry. We also calculated stoichiometric nitrogen (N) to phosphorus (P) ratios (N:P), as well as methane and nitrous oxide fluxes. The sampled chironomids were identified to genus level for all sampled months, apart from October, from which Shannon-Wiener taxonomic diversity was calculated. Additionally, genera were categorized into feeding groups based on literature and morphology from which functional feeding group Shannon-Wiener functional diversity was calculated. Â本数据集涵盖湿地养分、叶绿素a（chlorophyll-a）、甲烷（methane）与一氧化二氮（nitrous oxide）浓度数据，以及摇蚊（chironomid midges）羽化观测数据与水温数据。数据采集工作于2021年5月、6月、7月、8月及10月开展，采集期间同步获取了摇蚊羽化与水化学相关数据。本研究同时计算了氮（N）磷（P）化学计量比（N:P），以及甲烷与一氧化二氮的排放通量。除10月外，其余所有采样月份的摇蚊样本均被鉴定至属级水平；针对10月的采样样本，研究人员计算了香农-维纳分类多样性指数。此外，基于现有文献与形态学特征，研究团队将摇蚊属级类群划分为不同功能摄食类群，并据此计算了功能摄食类群的香农-维纳功能多样性指数。
