title: Data from: Landscape composition and life-history traits influence bat movement and space use: analysis of 30 years of published telemetry data

description: Aim: Animal movement determines home range patterns, which in
 turn affect individual fitness, population dynamics and ecosystem
 functioning. Using temperate bats, a group of particular conservation
 concern, we investigated how morphological traits, habitat specialization
 and environmental variables affect home range sizes and daily foraging
 movements, using a compilation of 30 years of published bat telemetry
 data. Location: Northern America and Europe. Time period: 1988 – 2016.
 Major taxa studied: Bats. Methods: We compiled data on home range size and
 mean daily distance between roosts and foraging areas at both colony and
 individual levels from 166 studies of 3,129 radiotracked individuals of 49
 bat species. We calculated multi-scale habitat composition and
 configuration in the surrounding landscapes of the 165 studied roosts.
 Using mixed models, we examined the effects of habitat availability and
 spatial arrangement on bat movements, while accounting for body mass,
 aspect ratio, wing loading and habitat specialization. Results: We found a
 significant effect of landscape composition on home range size and mean
 daily distance at both colony and individual levels. On average, home
 ranges were up to 42% smaller in the most habitat-diversified landscapes
 while mean daily distances were up to 30% shorter in the most forested
 landscapes. Bat home range size significantly increased with body mass,
 wing aspect ratio and wing loading, and decreased with habitat
 specialization. Main conclusions: Promoting bat movements through the
 landscape surrounding roosts at large spatial scales is crucial for bat
 conservation. Forest loss and overall landscape homogenization lead
 temperate bats to fly farther to meet their ecological requirements, by
 increasing home range sizes and daily foraging distances. Both processes
 might be more detrimental for smaller, habitat-specialized bats, less able
 to travel increasingly longer distances to meet their diverse needs.
description: Individual data includes the IDs of each individuals
 ('ID'), of each roost ('ID_site'), of each study
 ('ID_study'); the species name; the year of publication
 ('Year_publi') and the year of bat capture
 ('Year_capture'); the country where each study was conducted;
 the sex, age and reproductive status ('Status') of each
 individual; the scaled transmitter weight ('Trams_weight_sc');
 the scaled number of fixes ('n_fixes_sc'); the scaled number of
 nights of survey ('n_nights_sc'); the log-transformed the size
 of home range ('LogMCP'); the log-transformed daily distance
 movement between roost and foraging areas ('LogDist'); the
 scaled Human FootPrint index ('HFP_sc'), the scaled road density
 ('Densroad_sc'), the scaled forest proportion
 ('Forest_sc'), the scaled Shannon diversity index
 ('Divshan_sc') and the scaled number of forest patches
 ('Forest_np_sc'), the five last landscape variables are
 calculated at four different scales: 1: 1km radii; 5: 5km radii; 10: 10km
 radii; 20: 20km radii. The data also includes four life-history traits:
 scaled body mass (g); scaled aspect ratio; scaled wing loading and the
 scaled species specialization index ('SSI_sc').
 Mean data (colony level) includes the same variables (expect the
 sex, age and reproductive status) as for the individual data and the
 scaled number of individuals ('n_ind_sc') used to calculate the
 mean home range size and daily distance movement between the roost and the
 foraging areas.
