Oak masting remains stable despite climate warming

This repository contains the original seed production and climate datasets used in the study "Oak masting remains stable despite climate warming". The dataset includes long-term records of acorn production collected across forest sites in Poland, together with the associated temperature variables. Data files are provided in their processed form as used for the statistical analyses presented in the manuscript. The accompanying R code used to process the data, reproduce analyses, and generate figures is available in the associated GitHub repository: MastingTrends/tree/main Contents Seed production records for oak populations across Poland.
