This dataset consists out of four files, with data for bats, mice, moths and birds included in the paper indicated above. Data on bats (Spoelstra_2015_philtrans_BatsPerNightPerTRfile.txt): rank = observation level random effect (unique per record) night = night number, starting from the first of june 2013 site = site number, see table 'transects.csv' transect = transect number, see table 'transects.csv' treatment = light treatment, either dark, white, green or red passes = number of 5 second files with a pass of a pipistrellus species buzzes = number of buzzes per night Data on wood mice (2012-2015_SpeciesPerNightPerTransect.csv): recID = observation level random effect (unique per record) site = site number, see table 'transects.csv' transect = transect number, see table 'transects.csv' treatment = light treatment, either dark, white, green or red date = date nightnr = night number after 1/1/2012 year = year juliandate = juliandate species = species daytime = number of the species photographed in daytime nighttime = number of the species photographed in nighttime cam1 = camera at middel light post in the forest cam2 = camera at last light post in the forest cam3 = horizontal camera at middle light post in the forest totalOFFtile = total individuals photographed not on the tile totalONtile = total individuals photographed on the tile total = total individuals Data on birds (Spoelstra_2015_philtrans_Sovon_DiffTransYear_2012_2014.txt): Year = year Trans = transect number, see table 'transects.csv' Species = species number, refer to SOVON for NL or Latin name Number = number of individuals changed from Year to Year + 1 Site = site number, see table 'transects.csv' Tr = light treatment, either dark, white, green or red Data on moths (Spoelstra_2015_philtrans_MothSpecPerTransFile_2012_2013.txt): spectranscode = combination of species code and transect speciescode = code for moth species; see NL species list family = moth family order = moth order transect = transect number, see table 'transects.csv' Site = site number, see table 'transects.csv' nr.2012 = number of individuals caught in 2012 nr.2013 = number of individuals caught in 2013 catchnights.2012 = number of nights trapped in 2012 catchnights.2013 = number of nights trapped in 2013 absdiffyears = difference in individuals between 2013 and 2012 reldiffyears = relative differentce (corrected for trapping nights) ratioyears = ratio in numbers between 2013 and 2012 treatment = ight treatment, either dark, white, green or red Data on transects (transects.csv - link between site, transect, treatment): col1 = transect number col2 = site number col3 = NL name of site col4 = treatment col5 = data lights on for the first time
