Insectivorous bats alter their flight and feeding behaviour at ground-mounted solar farms
收藏资源简介：
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:<br> - dist_Eau_c -> distance to water bodies in meters for control sites<br> - dist_Eau_t -> distance to water bodies in meters for treatment sites<br> - dist_lisiere_c -> distance to woody edges in meters for control sites<br> - dist_lisiere_t -> distance to woody edges in meters for treatment sites<br> - foret_1000_c -> forest proportion in a 1000 meters radius around control sites<br> - 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 Definition of columns:<br> - temps (s) -> time elapsed since the beginning of the session in seconds<br> - x (m) -> position of the echolocation call on the X axis in metres relative to microphone 1<br> - -dx (m) -> lower limit of the 76% confidence interval of the X-axis position in metres <br> - +dx (m) -> upper limit of the 76% confidence interval of the X-axis position in metres<br> - y (m) -> position of the echolocation call on the Y axis in metres relative to microphone 1<br> - -dy (m) -> lower limit of the 76% confidence interval of the Y-axis position in metres <br> - +dy (m) -> upper limit of the 76% confidence interval of the Y-axis position in metres<br> - z (m) -> position of the echolocation call on the Z axis in metres relative to microphone 1<br> - -dz (m) -> lower limit of the 76% confidence interval of the Z-axis position in metres<br> - +dz (m) -> upper limit of the 76% confidence interval of the Z-axis position in metres<br> - fsigmax (Hz) -> frequency of the maximum signal energy determined by the microphone array system in Hz<br> - bande (Hz) -> bandwidth of the signal in Hz<br> - duree (s) -> duration of signal in seconds<br> - wav_name -> name of the .wav file containing the signal<br> - Species -> species automatically identified by Tadardia software<br> - Score -> confidence score of the automated species identification<br> - id_site -> site identifier<br> - typeSite -> type of site (C = control; T = treatment)<br> - date -> date<br> - time -> time<br> - IdTraj -> trajectory identifier<br> - Vfinal -> flight speed in meters per second<br> - Species_corrected -> species identity corrected following criteria explained in the manuscript<br> - guild -> guild (MRE = mid range echolocators; LRE = long range echolocators; SRE = short range echolocators; CF = constant frequency)<br> - dist_pos_prec -> distance of the position from the previous one in meters<br> - sinuosity -> sinuosity of the trajectory<br> - dist_extrem -> distance in meters between the first and the last positions of the trajectory<br> - sum_dist -> sum of all inter-position distances of the trajctory<br> - 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)<br> - buzz -> feeding buzz probability of the position<br> - meanBuzz -> mean feeding buzz probability of the trajectory<br>
