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
