Social interactions between animals can provide many benefits, including the ability to gain useful environmental information through social learning. However, these social contacts can also facilitate the transmission of infectious disease...
Brighter is better: bill fluorescence increases social attraction in a colonial seabird and reveals a potential link with foraging [0.03%]
更强的荧光效果更好：殖民海鸟的求偶行为中鸟喙荧光效果增强社会吸引力并可能与觅食存在某种联系

Crested auklets (Aethia cristatella) are colonial seabirds with brilliant orange bills during the breeding season. We characterized the bill pigment with spectroscopy methods (resonance Raman, fluorescence, absorbance). We excluded caroteno...
Dissecting the two mechanisms of scramble competition among the Virunga mountain gorillas [0.03%]
解析维龙加山地大猩猩之间两种混乱竞争机制
Andrew M Robbins,Cyril C Grueter,Didier Abavandimwe et al.
Andrew M Robbins et al.
Abstract: Two mechanisms have been proposed to explain why scramble competition can increase the travel requirements of individuals within larger groups. Firstly, individuals in larger groups may be more likely to encount...
The development and maintenance of sex differences in dietary breadth and complexity in Bornean orangutans [0.03%]
婆罗洲猩猩饮食范围和复杂性的性别差异的发展和维持
Caroline Schuppli,S Suci Utami Atmoko,Erin R Vogel et al.
Caroline Schuppli et al.
Abstract: Orangutans show a pronounced sexual dimorphism, with flanged males (i.e., males with fully grown secondary sexual characteristics) reaching twice the size of adult females. Furthermore, adult orangutans show sex...
Egg covering in cavity nesting birds may prevent nest usurpation by other species [0.03%]
腔巢鸟类的蛋覆盖行为可以防止其他物种侵占鸟巢

Abstract: Some birds cover their eggs with nest material when they leave to forage. It has been suggested that such egg-covering aids thermoregulation or prevents predation but here we present a new hypothesis, that secon...
A resource-poor developmental diet reduces adult aggression in male Drosophila melanogaster [0.03%]
资源匮乏的发育饮食降低雄性黑腹果蝇成虫的攻击性

Aggressive behaviours occur throughout the animal kingdom and agonistic contests often govern access to resources. Nutrition experienced during development has the potential to influence aggressive behaviours in adults through effects on gr...

Parasites and their social hosts form many different relationships. But what kind of selection regimes are important? A look at the parameters that determine fitness of the two parties suggests that social hosts differ from solitary ones pr...
Gregariousness is associated with parasite species richness in a community of wild chimpanzees [0.03%]
社群性与野生黑猩猩群体中的寄生虫丰富度相关

Increased risk of pathogen transmission through proximity and contact is a well-documented cost of sociality. Affiliative social contact, however, is an integral part of primate group life and can benefit health. Despite its importance to t...
The role of social structure and dynamics in the maintenance of endemic disease [0.03%]
社会结构和动态在地方病维持中的作用分析

Social interactions are required for the direct transmission of infectious diseases. Consequently, the social network structure of populations plays a key role in shaping infectious disease dynamics. A huge research effort has examined how ...

Abstract: Neophobia (the fearful reaction to novel stimuli or situations) has a crucial effect on individual fitness and can vary within and across species. However, the factors predicting this variation are still unclear...
