Home range sizes and proportions of outside-nest fixes of the radio-tracked mole-rats.

The home ranges (HR) are computed as a set of 4-m grid cells (GC) covering all radio-fixes and as the minimum convex polygon (MCP). Numbers in parentheses signify percentages from the whole family's HR. Exclusive HR size is an area of GCs which contain radio fixes of the focal individual only. Numbers in parentheses are the mean values expected under given sample size if no spatial preferences of the animals occur. The values were obtained based on 1000 permutations with coordinate pairs of the outside-nest fixes of all family non-breeders randomly exchanged. The p-values refer to the test of the hypothesis that the size of the exclusive HR is a by-product of the sample size (see Materials and methods for details).1)Including individuals which were not radio-tracked.

本研究中的家域（Home Range，HR）采用两种方式计算：一是覆盖所有无线电定位点的4米网格单元（Grid Cell，GC）集合，二是最小凸多边形（Minimum Convex Polygon，MCP）。括号内的数值代表其占整个家族家域的百分比。专属家域面积指仅包含目标个体无线电定位点的网格单元对应的区域。此处括号内的数值为：当动物无空间偏好时，基于给定样本量所预期得到的平均值。该数值通过1000次置换检验获得：将所有家族非繁殖个体的巢外定位点坐标对进行随机交换。P值用于检验"专属家域面积仅为样本量的副产物"这一假设（详细方法参见材料与方法）。1）包含未被无线电追踪的个体。
