本文对目前用于估计小型哺乳动物活动范围大小的主要方法进行了比较。该地区各部分的使用强度在生物学上是显著的，以及绝对的大小。常用的估计家庭活动范围的方法包括一个假设，即动物很少超出被困的区域。提出了一种计算“活动中心”位置的方法。被捕获的概率似乎随着离活动中心距离的增加而降低。陷阱显示的活动范围通常在最初的几次捕获中增长最快，之后相对较小。这被解释为动物达到了其活动范围的绝对极限，但也可能是诱捕机制的结果。真实射程与陷阱显示射程之间的关系有待进一步研究。分析。
A comparison is made between the principal methods now used for estimating size of home range from live-trapping "records of small mammals. The intensity of use of various portions of the area is biologically significant, as well as absolute size. The commonly-used methods for estimating size of home range involve an assumption that animals seldom range beyond the areas where trapped. A method is suggested for computing the location of a "center of activity." The probability of capture seems to decrease with increased distance from the center of activity. The trap-revealed home range usually increases most rapidly with the first few captures, and relatively little thereafter. This has been explained as an animal reaching the absolute limits of its home range, but it may be a result of the mechanics of trapping. The relationship between true home range and trap-revealed home range requires exptl. analysis.
