DOI: 10.1007/s10816-021-09514-w
Abstract: Using stable isotope mixing models (SIMMs) to quantify past diets is becoming increasingly common in archaeology. This study highlights important field-specific difficulties encountered by archaeologists in reconstructing palaeodiets using SIMMs. Focusing on the data acquisition… read more here.

DOI: 10.1016/j.jconhyd.2020.103658
Abstract: The rising food production to meet the growing human population has led to increased anthropogenic inputs of nutrients such as NO3- in groundwater and aquatic environments. Nitrate concentrations, hydrochemistry, and isotope data (δ18O-H2O, δ2H-H2O, 15N-NO3,… read more here.

DOI: 10.1371/journal.pone.0209411
Abstract: An extensive ecological literature applies stable isotope mixing models to derive quantitative dietary reconstructions from isotope ratios of consumer tissues. While this approach works well for some organisms, it is challenging for consumers with complex,… read more here.

DOI: 10.1371/journal.pone.0257818
Abstract: Stable isotope mixing models (SIMMs) provide a powerful methodology for quantifying relative contributions of several sources to a mixture. They are widely used in the fields of ecology, geology, and archaeology. Although SIMMs have been… read more here.

DOI: 10.1371/journal.pone.0277204
Abstract: Bayesian stable isotope mixing models are widely used in geochemical and ecological studies for partitioning sources that contribute to various mixtures. However, none of the existing tools allows accounting for the influence of processes other… read more here.
