AllDesertData_resample_adehabitat_output.csv from Animal movement and associated infectious disease risk in a metapopulation

Raw data file showing results after radio-collar data were resampled to 1 location per day for all individuals by removing extraneous locations such that consecutive locations for each animal were between 20 and 28 hours apart. In cases where locations were missing and time lags exceeded 28 hours, we retained the next location to allow for the next daily time step. We calculated daily movement rates from step-lengths (i.e., Euclidean distance between 2 consecutive locations measured in meters) divided by time lags between resampled locations, and multiplied rates by 24 hours to yield meters per day (m/day); time lag values (dt) are reported in seconds, longitudinal displacement (dx), latitudinal displacement (dy), and distance (dist) are reported in meters. Output was generated using adehabitatLT in Program R (Calenge 2019; R Development Core Team 2019).

本原始数据文件呈现了无线电项圈数据经重采样后的分析结果：针对所有研究个体，将定位数据重采样为每日1个定位点，通过剔除冗余定位点，使每只动物的连续定位点之间的时间间隔处于20至28小时之间。当出现定位点缺失且时间滞后超过28小时的情况时，我们保留下一个有效定位点以确保后续每日时间步的连续性。我们通过步长（即两个连续定位点间以米为单位的欧氏距离）除以重采样后定位点间的时间滞后量，计算每日移动速率，并将速率乘以24小时，得到以米每日（m/day）为单位的移动结果；其中时间滞后值（dt）以秒为单位记录，经度位移（dx）、纬度位移（dy）及距离（dist）均以米为单位。本分析结果通过R程序中的adehabitatLT包生成（Calenge 2019；R Development Core Team 2019）。
