Data and code from: Phenotypic plasticity masks evolutionary change in grassland plant traits in response to land use abandonment

Traditionally-managed grasslands are among the most biodiverse habitats in Europe, but are threatened by land use abandonment. While the negative impacts of grazing and mowing cessation on species richness are well documented, little is known about potential evolutionary changes within species. Yet, intraspecific functional diversity is critical for successful grassland restoration and ensuring adaptive potential to future climate change. To disentangle the heritable and non-heritable components of population-level response to land use change in semi-natural grasslands, we examined 22 populations of a common grass, Briza media, from grazed sites and sites where grazing was abandoned, with resulting tree and shrub encroachment. We measured a range of traits under field conditions and following clonal propagation under common garden conditions. Field surveys revealed that abandonment resulted in litter accumulation, greater shading by woody and herbaceous vegetation, and lower temperature..., , # Data and code from: Phenotypic plasticity masks evolutionary change in grassland plant traits in response to land use abandonment

## Description of the data and file structure

All data analyses were done in R Studio Version 2023.06.0+421 (2023.06.0+421). Before you start using the script, please run all data files first, because some graphs and tables contain information from several csv files. 

To make all data work, please, run the following packages: library(lme4), library(car), library(performance), library(ggplot2), library(vegan), library(tidyverse), library(marginaleffects), library(ggplot2), ibrary(ggsci), library(patchwork), library(ggpubr), library(hypervolume).

The input files to replicate the statistical analyses are the following:

`Briza_field_2022data_correct.csv`
