Barré et al_PV2023

The repository contains the R script used for analyses and the three associated .csv data files:

# R script: analyses_PV_trajecto.R 

# Dataset containing site and pair identifiers: Data_env_PV.csv 

# Dataset containing the landscape features of pairs sampled for testing the standardization of the sampling design: Data_env_PV2.csv 

Definition of columns:
- dist_Eau_c -> distance to water bodies in meters for control sites
- dist_Eau_t -> distance to water bodies in meters for treatment sites
- dist_lisiere_c -> distance to woody edges in meters for control sites
- dist_lisiere_t -> distance to woody edges in meters for treatment sites
- foret_1000_c -> forest proportion in a 1000 meters radius around control sites
- foret_1000_t -> forest proportion in a 1000 meters radius around treatment sites

# Dataset containing 3D bat positions and feeding behaviour metrics: dataFinal_buzz2.csv

- dist_extrem -> distance in meters between the first and the last positions of the trajectory
- sum_dist -> sum of all inter-position distances of the trajctory
- angle_mort ->    blind angle at control sites (oui = yes, i.e. positions that should be removed from the analyses at control sites, see the main text for more details)
