Amazon tree ring isotope records of Macrolobium acaciifolium and Cedrela odorata
The data consist of tree ring oxygen (δ18Otr) and carbon (δ13Ctr) isotope data of Macrolobium acaciifolium and Cedrela odorata from five sites in the Amazon basin, including Pacaya (Peru) and Maranon (Peru), Leticia (Colombia), Manuripi (Bolivia) and Riberalta (Bolivia).
All sample preparation (i.e., cutting ring sections, cellulose extraction, weighing and packing) was done at the University of Leeds, and all isotope ratio measurements were done at Stable Isotope Laboratory at the University of Leicester.

Provenance & quality
All sample preparation (i.e., cutting ring sections, cellulose extraction, weighing and packing) was done at the University of Leeds, and all isotope ratio measurements were done at Stable Isotope Laboratory at the University of Leicester. Cellulose was extracted directly from wood cross-sectional slices following the procedure of Kagawa et al. (2015): cross-sectional slices of 1-4mm thickness and 6-8 cm length were cut from the core samples with a circular diamond saw blade and packed in TEFLON perforated sheets. Cellulose was extracted from the raw wood material following the chemical procedure of Wieloch et al. (2011).
