Quantifying the costs of mating is key for understanding life-history trade-offs. As a reflection of metabolic rate, body temperature is one metric for assaying these costs. However, conventional methods for measuring body temperature are i...
Competitive ability determines coalition participation and partner selection during maturation in wild male chimpanzees (Pan troglodytes schweinfurthii) [0.03%]

Social mammals often live in groups in which a dominance hierarchy is an important determinant of access to mates. In addition to competing individually, males may form coalitions of two or more to attack or intimidate rivals. Coalition for...

We social animals must balance the need to avoid infections with the need to interact with conspecifics. To that end we have evolved, alongside our physiological immune system, a suite of behaviors devised to deal with potentially contagiou...

High road mortality during female-biased larval dispersal in an iconic beetle [0.03%]
在一种标志性甲虫中，在以幼虫偏雌性扩散期间公路死亡率较高

Topi K Lehtonen et al.
Abstract: Animals often disperse from one habitat to another to access mates or suitable breeding sites. The costs and benefits of such movements depend, in part, on the dispersing individuals' phenotypes, including their...
The cost of associating with males for Bornean and Sumatran female orangutans: a hidden form of sexual conflict? [0.03%]
婆罗洲和苏门答腊雌性猩猩与雄性接近的代价——一种隐藏形式的两性冲突吗？
Julia A Kunz,Guilhem J Duvot,Maria A van Noordwijk et al.
Julia A Kunz et al.
Abstract: Sexual coercion, in the form of forced copulations, is relatively frequently observed in orangutans and generally attributed to their semi-solitary lifestyle. High ecological costs of association for females may...

Differences in incubation behaviour and niche separation of two competing flycatcher species [0.03%]
两种竞争性蝇捕食者在孵卵行为和生态位分离上的差异

Abstract: Food availability sets the stage for incubation behaviour of a female bird and thereby indirectly determines the nest temperature, which in turn affects development and metabolism of avian embryos. Changes in de...
Grouped circular data in biology: advice for effectively implementing statistical procedures [0.03%]
生物学中的分组圆形单数据：有效实施统计程序的建议

Abstract: The most common statistical procedure with a sample of circular data is to test the null hypothesis that points are spread uniformly around the circle without a preferred direction. An array of tests for this ha...

Sensitivity to variance, or risk, has been considered elementary to economic decision making, featured prominently in discussions of primate species-typical behaviors and phylogeny, and heralded as a challenge to deterministic foraging theo...
