Amazon Tree Ring Oxygen and Carbon Isotope Records from Five Sites

Tree ring oxygen (δ18Otr) and carbon (δ13Ctr) isotope data for Macrolobium acaciifolium and Cedrela odorata species. The dataset covers five sites in the Amazon basin across Peru, Colombia, and Bolivia, with sample preparation at the University of Leeds and isotope measurements at the University of Leicester.

Use Cases

• Analyze δ18Otr and δ13Ctr isotope variations across the five Amazon basin sites to study regional climate signals.
• Compare isotope records between Macrolobium acaciifolium and Cedrela odorata species to investigate species-specific physiological responses.
• Reconstruct historical Amazonian hydroclimate by modeling the relationship between δ18Otr data from sites like Pacaya and Maranon with precipitation records.

Strengths

• Includes isotope data from five distinct geographical sites in the Amazon basin.
• Covers two different tree species, Macrolobium acaciifolium and Cedrela odorata.
• Sample preparation and isotope ratio measurements were conducted at specialized university laboratories.

Limitations

• The number of individual tree ring samples (rows) and measured variables (columns) is unknown.
• Data is packaged in a ZIP file without immediate visibility into the internal file structure or format.
• Temporal coverage and the specific years represented by the tree rings are not specified.
