title: Heterospecific-neighbor-mediated changes in density and size increase prey capture by a carnivorous plant

description: Description

This repository contains the data and R code used for generating the results in the article “Heterospecific-neighbor-mediated changes in density and size increase prey capture by a carnivorous plant” published in Oikos.

 

Repository structure

1.   Folder “01_Data_Raw”

This folder contains the original dataset during the data collection process.

1)    File "Sundew_Data.xlsx": This file contains the raw data on plant densities, sundew traits, prey capture, and insect communities in the habitats with varying neighboring plant densities.

 

2.    Folder “02_R_Code”

This folder contains the R scripts for data analyses and visualization.

1)    File "01_Models_Plant_Density.R": This script analyzes the densities of sundews and neighboring plant flowerheads in the habitats with varying neighboring plant densities.

2)    File "02_Models_Sundew_Traits.R": This script analyzes the sundew traits (rosette diameter and number of leaves) in the habitats with varying neighboring plant densities.

3)    File "03_Models_Prey_Captured.R": This script analyzes the prey capture performance and prey composition of sundews in the habitats with varying neighboring plant densities.

4)    File “04_Models_Insect_Communities.R": This script analyzes the insect abundance and composition in the habitats with varying neighboring plant densities as well as the flowerhead removal plots.

5)    File "05_Figures.R": This script generates the figures in the manuscript.

 

3.    README.md

This markdown file contains the descriptions for the data and R code in this repository.
