This dataset is a meta-analysis of primary producer amino acid δ15N data presented in Ramirez et al. (2021). A literature review provided primary producer amino acid isotope data with ecologically relevant information to examine beta variability in trophic position estimates.
This dataset represents information from a meta-analysis of primary producer amino acid δ15N data that were published in Ramirez et al. (2021) [https://doi.org/10.1111/2041-210X.13678].
This meta-analysis fulfills a pressing need to comprehensively evaluate relevant sources of β value variability and its contribution to the uncertainty in trophic position compound specific isotope analysis (TPCSIA). We first synthesized all published primary producer AA δ15N data to investigate ecologically relevant sources of variability (e.g. taxonomy, tissue type, habitat type, mode of photosynthesis). We then reviewed the biogeochemical mechanisms underpinning AA δ15N and β value variability.
