利用 25 只个体（13 只雌性；12 只雄性）的无线电跟踪位置和 9 个习惯个体的视觉观察，研究了喀拉哈里南部蜜獾的空间组织和运动模式。成年雄性蜜獾的活动范围（541 +/- 93 km(2)）明显大于成年雌性蜜獾的活动范围（126 +/- 13 km(2)）。雌性的活动范围大小是根据体重预测的五倍。雌性的广泛活动范围可能是由于半干旱的喀拉哈里沙漠猎物供应相对较低以及幼崽依赖时间较长（12-16个月）的结果。雌性的平均活动范围重叠程度适中（13%），并且活动范围中心有规律地分布，雌性似乎没有积极保卫领地，也没有观察到雌性之间的直接互动。气味标记似乎可以调节时空分离，而雌性则表现出松散的领地间距模式。相比之下。雄性不支持典型的鼬科动物的性内领地模式，而是包含多达 13 只雌性的重叠的活动范围。雄性和雌性在活动期间的移动速度（3.8 +/- 0.3 km/h vs 2.7 +/- 0.2 km/h）、直线运动（6.2 +/- 0.5 km vs 2.4 +/- 0.2 km）和实际移动距离（13.8 +/- 0.9 km vs 7.7 +/- 0.7 km）存在显着差异，但其活动范围百分比没有差异单日遍历次数（3%）。年轻雄性的活动范围往往比成年雄性小（1-45公里），并且与成年雄性相比，其间距模式更类似于成年雌性。与其他独居鼬科动物一样，其空间组织表明一夫多妻或混杂的交配系统。
Radio-tracking locations of 25 individuals (13 females; 12 males) and visual observations of nine habituated individuals were used to investigate the spatial organization and movement patterns of the honey badger Mellivora capensis in the southern Kalahari. The home ranges of adult male honey badgers (541 +/- 93 km(2)) were significantly, larger than the home ranges of adult females (126 +/- 13 km(2)). Female home-range size was five times larger than predicted from body mass. The extensive home ranges of females were likely to he a function of relatively low prey availability in the semi-arid Kalahari and the long period of cub dependence (12-16 months). mean home-range overlap in females was moderate (13%) and home-range centres were regularly spaced, females did not appear to actively defend a territory and no direct interactions between females were observed. Scent marking appears to mediate spatio-temporal separation and females show a loosely territorial spacing pattern. In contrast. males did not support the typical mustelid pattern of intra-sexual territoriality but instead encompassed the overlapping home ranges of up to 13 females. Males and females differed significantly in their rate of travel (3.8 +/- 0.3 km/h vs 2.7 +/- 0.2 km/h), straight line (6.2 +/- 0.5 km vs 2.4 +/- 0.2 km) and actual distance (13.8 +/- 0.9 km vs 7.7 +/- 0.7 km) moved during an active period but do not differ in the percentage of their home-range area traversed in a single day (3%). Young males tended to have smaller home ranges (1 45 km) than adult males and Showed a spacing pattern more similar to adult females than adult males. In common with other solitary mustelids, the spatial organization suggests a polygynous or promiscuous mating system.
