Nutritional dynamics in fungus-growing termites: integration of biological nitrogen fixation and microbial amino acids

This dataset compiles δ¹³C and δ¹⁵N values of individual amino acids from a range of basal essential amino acid (EAA) sources in terrestrial ecosystems, including plants, fungi, and bacteria. It includes data generated in the current study (Vesala et al. 2025) alongside data collated from nine earlier published studies (Besser et al., 2022; Larsen et al., 2009, 2012, 2013, 2016; Manlick et al., 2023; Pollierer et al., 2019, 2020; Scott et al., 2006). Full references and web links to the original data are given in the data file. The dataset was created to enable comprehensive linear discriminant analysis (LDA) of δ¹³C-EAA profiles across diverse basal resources.
