摘要

在原猿灵长类动物中,尿液标记一直被忽视。圈养研究表明,马达加斯加原猴狐猴用尿液以及专门的沉积物来标记气味。L. catta尿标是一种多模态信号,与简单的排尿有不同的设计特征,包括尾巴的结构:在标记时尾巴向上举起(UT-up),在排尿时尾巴向下(UT-down)。我们探讨了UT-up在雌优势油菜中的经济性和功能。我们收集了在Berenty(马达加斯加南部)的一个群体在非交配期240小时的观察结果。我们收集了行为回合/环境(标记,旅行,喂食,休息和打架)并记录了191次ut -up和79次ut -down。通过全球定位系统,我们确定了i)群体外个体和ii)群体成员经常光顾的地方的位置,在这种情况下,还记录了行为背景和在每个地方花费的时间。我们发现L. catta UT-up并不是圈养的产物。此外,非交配期的UT-up还具有领土防御的作用,在羊草社会中主要由雌性完成。女性仰卧起坐被调查的最多,女性仰卧起坐被调查的更多。最后,信号的使用是节省的,因为尿液被放置在竞争对手发现概率更高的地方和时间。在群外个体最常光顾的地方和有群外竞争者在场的情况下(非随机地形和时间)进行ut -up。总之,我们认为UT-up是一种经济信号,主要具有地域功能。

Multimodal signaling in wild Lemur catta: economic design and territorial function of urine marking.

Urine marking has been neglected in prosimian primates. Captive studies showed that the Malagasy prosimian Lemur catta scent marks with urine, as well as via specialized depositions. L. catta urine mark, a multimodal signal, differs from simple urination in terms of different design features, including tail configuration: the tail is held up during marking (UT-up) and down during urination (UT-down). We explore economy and function of UT-up in the female dominant L. catta. We collected 240 h of observations on one group at Berenty (south Madagascar) during the nonmating period via all occurrences sampling. We gathered behavioral bouts/contexts (marking, traveling, feeding, resting, and fights) and recorded 191 UT-ups and 79 UT-downs. Via Global Positioning System we established the location of the places frequented i) by extragroup individuals and ii) by group members, in this case recording also behavioral context and time spent in each place. We found that L. catta UT-up is not an artifact of captivity. Moreover, UT-up in the nonmating period plays a role in territorial defense, which is mostly performed by females in L. catta society. Female UT-ups were the most investigated and UT-ups were performed/investigated more by females. Finally, signal use is parsimonious, in that urine is economically placed where and when detection probability by competitors is higher. UT-ups were performed in places most frequented by extragroup individuals and in presence of extragroup competitors (nonrandom topography and timing). In conclusion, we suggest that UT-up is an economical signal with a primarily territorial function.

期刊介绍: The American Journal of Physical Anthropology (AJPA) is the official journal of the American Association of Physical Anthropologists. The Journal is published monthly in three quarterly volumes. In addition, two supplements appear on an annual basis, the Yearbook of Physical Anthropology, which publishes major review articles, and the Annual Meeting Issue, containing the Scientific Program of the Annual Meeting of the American Association of Physical Anthropologists and abstracts of posters and podium presentations. The Yearbook of Physical Anthropology has its own editor, appointed by the Association, and is handled independently of the AJPA. As measured by impact factor, the AJPA is among the top journals listed in the anthropology category by the Social Science Citation Index. The reputation of the AJPA as the leading publication in physical anthropology is built on its century-long record of publishing high quality scientific articles in a wide range of topics.
