Factors influencing space-use and kill distribution of sympatric lion prides in a semi-arid savanna landscape

In this study, Global Positioning System collar data and logistic regression were used to investigate space-use and kill distribution among three lion prides at Malilangwe Wildlife Reserve, Zimbabwe. The R statistical platform was used to perform logistic regression analysis to determine the effects of the environmental variables on the outcome of each pride's ranging behaviour. Presence/Kill probability (presence or absence) was used as a response variable while distance to water, shrub canopy volume, soil depth and clay content were treated as fixed effects.本研究利用项圈式全球定位系统（Global Positioning System）采集的数据与逻辑回归分析方法，针对津巴布韦马里兰加野生动物保护区内的3个狮群，探究其空间利用模式与捕食分布特征。本研究采用R统计分析平台开展逻辑回归分析，以明确各类环境变量对各狮群活动范围行为的影响效应。本研究以出现/捕食概率（即存在与否）作为响应变量，将距水源距离、灌丛冠层体积、土壤深度与黏粒含量设为固定效应。
