Dataset for: Pulsed evolution shaped extant angiosperm pollen disparity

This repository contains the primary data and scripts underlying the analyses presented in this study on angiosperm pollen morphological evolution and disparity. The files include the original morphological character matrix, time-calibrated phylogenetic trees, molecular sequence data, distance matrices, and all scripts required to reproduce the main results and figures.

Specifically, Data1_Original_coding_matrix.xlsx provides the genus-level discrete pollen character matrix used for morphospace, disparity, and evolutionary-rate analyses. Data2_MCCtrees.zip contains three time-calibrated angiosperm phylogenies (Triassic, Jurassic, and Cretaceous crown scenarios) in NEXUS format, which were used for disparity-through-time and rate analyses. Data3_Molecular_Dataset.nex includes the molecular alignment used to infer angiosperm phylogenetic relationships. Data4_Configuration file.txt contains the configuration file used for divergence-time estimation with TreePL. Data5_Distance_Matrix.zip provides the MORD morphological distance matrices (α = 0.5) used for ordination, disparity, and convergence analyses. Data6_Scripts.zip includes all R scripts used to perform ordinations (NMDS, PCoA), disparity calculations, bootstrap analyses, rate tests, and figure generation.
