Title | Encounter_ClassificationEM |
---|---|

Downloaded | 12 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 | 17 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). |

Downloaded | 11 times |

Description | Data used to asses habitat selection function of lions (RSF). Column headings: Id = id of lion, DateTime = local date and time of the GPS fixes of lions, Year = year, isNight = binary variable indicating if GPS fixes occurred at nighttime (1) or daytime (0), DistWater = distance to artificial waterhole in km, Case = binary response with 1 for GPS fixes and 0 for random locations, Grassland = binary variable with 1 if location occurred 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). |

Title | SSF_DelayedFlight_Immediately |

Downloaded | 12 times |

Description | Data used to asses the step selection function (SSF) of zebras using the delayed-flight tactic immediately after an encounter with lions (question 4). Column headings: id = id of zebra, FakeTime = 2-case, case = binary variable with 1 for an observed step and 0 for a random step, strata = id of the stratum where an observed step is paired with 10 random steps, TacticCont = categorical variable indicating if the step occurred after an encounter ("Tactic") or during the proactive phase ("Control"), Grassland = binary variable with 1 if the step ended in grassland and 0 if not, Bushland-1 = binary variable, Bushland-2 = binary variable, Bushland-3 = binary variable, Woodland = binary variable, Spline1-4 = spline variable for step length in m, StepLength = length of the step in m. |
