Elevated atmospheric CO2 alters the multi-element stoichiometry of pollen-bearing oak flowers, with possible negative effects on bees - raw data

Dataset for the article titled “Elevated atmospheric CO2 alters the multi-element stoichiometry of pollen-bearing oak flowers, with possible negative effects on bees”. Dataset contains elemental concentration data for 12 elements (C, N, P, S, K, Na, Ca, Mg, Cu, Zn, Fe, and Mn) measured in pollen-bearing flowers of pedunculate oak (Quercus robur). Samples were collected from both ambient CO2 (aCO2) and elevated CO2 (eCO2) treatments at the Birmingham Institute of Forest Research (BIFoR) Free Air Carbon Enrichment (FACE) facility. The measurements were performed at Jagiellonian University.
