The home range of the desert scorpion Paruroctonus mesaensis is analyzed using techniques of Ford & Krumme (1979). Possible factors influencing home range geomtry of P. mesaensis include prey distribution, prey abundance and renewal, energy requirements, risk of predation and body size. There are differences in home range size among the three year classes with the youngest year class maintaining a significantly smaller home range. Home ranges of each year class are approximately circular indicating that these scorpions are remarkably symmetric in the directional use of space around their burrow. The majority of surface activity occurs within 1.0 m from the burrow for all ages. These patterns along with equal probabilities of prey capture at all distances from the burrow suggest that scorpions do not deplete prey within their home ranges.
利用福特和克鲁姆（1979年）的技术分析了沙漠蝎子梅萨平尾蝎的活动范围。影响梅萨平尾蝎活动范围几何形状的可能因素包括猎物分布、猎物丰度和更新情况、能量需求、被捕食风险和体型。三个年龄组的活动范围大小存在差异，最年幼的年龄组活动范围明显更小。每个年龄组的活动范围大致呈圆形，这表明这些蝎子在洞穴周围空间的定向利用上非常对称。所有年龄段的蝎子大部分地表活动都发生在距洞穴1.0米范围内。这些模式以及在距洞穴所有距离处捕获猎物的概率相等表明，蝎子不会在其活动范围内耗尽猎物。
