Title Encounter_ClassificationEM
Downloaded 9 times
Description Data used to classify the immediate spatial responses of zebras after an encounter with lions between stay and flight. Column headings: Id = id of zebras, DateTime = local date and time of the GPS fixes of zebras, DistToLion = distance between zebra and lion at the time of the encounter in m, NetDisplacement = net displacement of zebra two hours after the encounter with lion in m.

Title Encounter_RSF
Downloaded 15 times
Description Data used to determine the habitat features of encounter areas and the habitat determinants of immediate response choice (stay or flight). Column headings: Id = id of zebra, DateTime = local date and time of the GPS fixes of zebras, Encounter = dependent categorical variable indicating if an encounter occurred ("Yes") or not ("No") at a given time, Encounter2 = dependent categorical variable (question 2) indicating if zebras stay ("Stay") or flee ("Flight") after encountering lions, DistWater = distance to artificial waterholes in km, Grassland = binary variable with 1 if zebra was in grassland and 0 if not, Bushland-1 = binary variable, Bushland-2 = binary variable, Bushland-3 = binary variable, Woodland = binary variable, Wooded Bushland = binary variable (reference category).
