Data from: Stable isotopes indicate consistent trophic structures but marked spatial variation in isotopic values across contrasting high-altitude Andean salars

<p dir="ltr">This dataset contains the supplementary data tables (Tables S1–S5) associated with the manuscript "Stable isotopes indicate consistent trophic structures but marked spatial variation in isotopic values across contrasting high-altitude Andean salars" by Salazar et al, submitted to Isotopes in Environmental & Health Studies.</p><p dir="ltr">The study used δ¹³C, δ¹⁵N and δ³⁴S values of primary producers, aquatic invertebrates and flamingos (feathers and faeces) from three high-altitude Andean salars in northern Chile (Laguna Puilar, Salar de Tara and Salar de Pujsa) to compare trophic structure and isotopic niche organisation.</p><p dir="ltr">Files included:</p><p dir="ltr">- Table S1: Raw stable isotope dataset (δ¹³C, δ¹⁵N, δ³⁴S) for all sampled taxa and salars.</p><p dir="ltr">- Table S2: Principal Coordinates Analysis (PCoA) scores.</p><p dir="ltr">- Table S3: Analytical standards and QA/QC data for isotope measurements.</p><p dir="ltr">- Table S4: Morphometric and environmental site characteristics of the three salars.</p><p dir="ltr">- Table S5: Pairwise posterior probabilities from the Bayesian hierarchical model of isotopic diversity indices.</p>
