初步研究表明，最近描述的殖民tuco-tuco（Ctenomys sociabilis）是社会的。作为描述该物种行为生态学特征的努力的一部分，我们研究了自由生活的C。sociabilis位于阿根廷内乌肯省南部。多达五个成年人（一名男性，四名女性）被抓获在一个单一的殖民地（空间上不同的集群洞穴入口）。利用无线电遥测技术监测了来自三个殖民地的八只成虫之间的空间关系。每只动物仅在单个群体中活动。在每个群体内，不同成虫使用的区域广泛重叠（（X）条大于或等于68%），所有动物共用一个巢址。总的来说，这些数据表明，C。sociabilis由一个单一的洞穴系统，可能居住着多个成年人。我们建议对C. sociabilis和其它群体分类群（例如，殖民地非洲鼹鼠; Bathyergidae）将大大提高我们对地下啮齿动物中有利于社会性的因素的理解。
Preliminary studies indicate that the recently described colonial tuco-tuco (Ctenomys sociabilis) is social. As part of efforts to characterize the behavioral ecology of this species, we examined patterns of use of burrows by members of a free-living population of C. sociabilis located in southern Neuquen Province, Argentina. As many as five adults (one male, four females) were captured within a single colony (spatially distinct cluster of burrow entrances). Spatial relationships among eight adults from three colonies were monitored using radiotelemetry. Each animal was active in only a single colony. Within each colony, the areas used by different adults overlapped extensively ((X) over bar greater than or equal to 68%) and all animals shared a single nest site. Collectively, these data indicate that a colony of C. sociabilis consists of a single burrow system that may be inhabited by multiple adults. We suggest that comparative analyses of C. sociabilis and other colonial taxa (e.g., colonial African mole-rats; Bathyergidae) will significantly improve our understanding of the factors favoring sociality among subterranean rodents.
