data_zebra_encounter_risk_Wet

Zebra data used to assess the relative effect of diel migration and change in vegetation cover on decrease in encounter risk with lions during the wet season. id = individual ID ; daytrack = the daytrack ID ; median_distwater_day = the median distance to waterhole (in km) over all GPS locations at day in a given daytrack ; median_distwater_night = the median distance to waterhole (in km) over all GPS locations at night in a given daytrack ; daytime_risk = actual daytime risk (situation 1) ; nighttime_risk_no_adjustment = hypothetical nighttime risk in absence of behavioural adjustments (situation 3) ; nighttime_risk_dm = hypothetical nighttime risk with diel migration only (situation 4) ; nighttime_risk = actual nighttime risk (situation 2) ; DM = diel migration away from waterholes in km本数据集为斑马（Zebra）观测数据，用于评估湿季时段内，昼夜迁移（diel migration）与植被覆盖变化对降低与狮子（lion）遭遇风险的相对影响。 各字段说明如下：id为个体标识号（individual ID）；daytrack为单日追踪标识（daytrack ID）；median_distwater_day为单次单日追踪周期内，所有日间GPS定位点到水坑的中位距离（单位：千米，km）；median_distwater_night为单次单日追踪周期内，所有夜间GPS定位点到水坑的中位距离（单位：千米，km）；daytime_risk为实际日间风险（情景1）；nighttime_risk_no_adjustment为未进行行为调整时的假设夜间风险（情景3）；nighttime_risk_dm为仅通过昼夜迁移实现风险调整的假设夜间风险（情景4）；nighttime_risk为实际夜间风险（情景2）；DM为远离水坑的昼夜迁移距离（单位：千米，km）
