Evolution of signal structure should be influenced by the social environment in which signals are sent and received. The "social complexity hypothesis" for communicative complexity postulates that individuals living in complex social groups...

Abstract: Understanding variation in reproductive skew between and within cooperatively breeding species is a key aim of social evolution. However, tests of reproductive skew models give equivocal results, potentially bec...
Collective behavior diverges independently of the benthic-limnetic axis in stickleback [0.03%]

Comparing populations across replicate environments or habitat types can help us understand the role of ecology in evolutionary processes. If similar phenotypes are favored in similar environments, parallel evolution may occur. Collective b...
Cofeeding at rich clumped food patches in free-ranging dogs: social tolerance or scramble competition? [0.03%]
在野外生活的狗中，富含食物的区域是否会导致社会容忍或掠夺竞争？

Andreas Berghänel et al.
Abstract: Animals are generally expected to monopolize food patches whenever possible. However, cofeeding within a defendable range occurs in many species, particularly at larger food patches, but the mechanism behind tha...
Socioecological drivers of injuries and aggression in female and male rhesus macaques (Macaca mulatta) [0.03%]

Abstract: Competition over access to resources, such as food and mates, is one of the major costs associated with group living. Two socioecological factors believed to drive the intensity of competition are group size and...

The interconnecting links between individuals in an animal social network are often defined by discrete, directed behaviours, but where these are difficult to observe, a network link (edge) may instead be defined by individuals sharing a sp...
Phenotypic Correlates of Pelvic Spine Coloration in the Threespine Stickleback (Gasterosteus aculeatus): Implications for Function and Evolution [0.03%]

Animal color patches may be static or plastic in expression and concealable or continuously visible, yet the evolution and function of these aspects of coloration have seldom been studied together. We investigated such color pattern element...
Exploring links between personality traits and their social and non-social environments in wild poison frogs [0.03%]

An animal's behavioral phenotype comprises several traits, which are hierarchically structured in functional units. This is manifested in measured behaviors often being correlated, partly reflecting the need of a coordinated functional resp...

Abstract: The role of visual search during bee foraging is relatively understudied compared to the choices made by bees. As bees learn about rewards, we predicted that visual search would be modified to prioritise rewardi...
Wild and captive immature orangutans differ in their non-vocal communication with others, but not with their mothers [0.03%]
野生和圈养的未成熟猩猩在与他人而非与母亲进行非声音交流的方式上有所不同

Abstract: In many group-living species, individuals are required to flexibly modify their communicative behaviour in response to current social challenges. To unravel whether sociality and communication systems co-evolve,...
