title: Repository containing field data, Excel files, and R scripts for the analyses in "Thicket Formation and Light Limitation Drive Patch-Scale Vegetation Transitions in a Semi-Arid Savanna."

description: This repository contains field-collected vegetation and environmental data, Excel spreadsheets, R scripts, and output figures used in the analyses for the manuscript “Thicket Formation and Light Limitation Drive Patch-Scale Vegetation Transitions in a Semi-Arid Savanna.” The dataset includes woody and herbaceous species composition, canopy cover, light transmittance, and leaf area index (LAI) data collected from 51 sites along a woody encroachment gradient at Endwell Farm, Eastern Cape Province, South Africa. Historical aerial imagery from 1949–2021 was used to assess woody cover changes, complemented by cluster analysis, indicator species analysis, and quantile regression. The repository also includes README files describing data structure and instructions for running the R scripts.

Each dataset includes a dedicated README Word document explaining variable definitions and data structure:

Description




Readme_CoverLightTrees.docx
Describes columns and variables in CoverLightTrees.xlsx.


Readme_Env.docx
Describes variables in Env.xlsx.


Readme_indicator_values(all).docx
Explains outputs from the IndVal (Indicator Species) analysis.


Readme_Matrices.docx
Describes structure and variable coding of species abundance matrices (MatrixHerb, MatrixTree, and MatrixTreeHerb).




 

R Scripts (used to generate figures in the manuscript)

Each R file corresponds to a figure or analysis step described in the paper:

Force X – Combined force from the two axes in the x-direction.

Force Y – Combined force from the two axes in the y-direction.

Absolute Position Axis 1 - 4 – Position of each axis (1 to 4), measured from the pre-defined machine setup.

Absolute Displacement X – Combined displacement in the x-direction, calculated using the absolute positions of the relevant axes.

Absolute Displacement Y – Combined displacement in the y-direction, calculated using the absolute positions of the relevant axes.

Force 1 - 4 – Force measured individually on axes 1 to 4.

Relative Position Axis 1 - 4 – Position of each axis (1 to 4), with the starting position at 0 mm.
