Volatile fatty acid and aldehyde abundances evolve with behavior and habitat temperature in Sceloporus lizards [0.03%]
行为和栖息地温度影响鬣蜥中挥发性脂肪酸和甲醛的含量变化

Animal signals evolve by striking a balance between the need to convey information through particular habitats and the limitations of what types of signals can most easily be produced and perceived. Here, we present new results from field m...
Out in the open: behavior's effect on predation risk and thermoregulation by aposematic caterpillars [0.03%]
在外公开：行为对显眼蝶蛾幼虫的捕食风险和体温调节的影响

Warning coloration should be under strong stabilizing selection but often displays considerable intraspecific variation. Opposing selection on color by predators and temperature is one potential explanation for this seeming paradox. Despite...
Phenotypic flexibility in background-mediated color change in sticklebacks [0.03%]

Phenotypic flexibility may incur a selective advantage in changing and heterogeneous environments, and is increasingly recognized as an integral aspect of organismal adaptation. Despite the widespread occurrence and potential importance of ...

In many mammals, breeding females are intolerant of each other and seldom associate closely but, in some, they aggregate in groups that vary in size, stability, and kinship structure. Aggregation frequently increases competition for food, a...
Extraterritorial forays by great tits are associated with dawn song in unexpected ways [0.03%]

Conspicuous male signals often play an important role in both attracting mates and deterring rivals. In territorial species with extrapair mating, female and male forays to other territories may be an important component underlying female c...
Defense against predators incurs high reproductive costs for the aposematic moth Arctia plantaginis [0.03%]
具有警戒色的植物花蛾（Arctia plantaginis）防御捕食者的策略会产生高昂的繁殖代价

To understand how variation in warning displays evolves and is maintained, we need to understand not only how perceivers of these traits select color and toxicity but also the sources of the genetic and phenotypic variation exposed to selec...
Risk exposure trade-offs in the ontogeny of sexual segregation in Antarctic fur seal pups [0.03%]
南极毛皮海豹幼仔性二态分离的风险暴露权衡机制研究

Sexual segregation has important ecological implications, but its initial development in early life stages is poorly understood. We investigated the roles of size dimorphism, social behavior, and predation risk on the ontogeny of sexual seg...
Physical and social cues shape nest-site preference and prey capture behavior in social spiders [0.03%]
物理和社会暗示塑造了社巢选择和捕食行为

Animals often face conflicting demands when making movement decisions. To examine the decision process of social animals, we evaluated nest-site preferences of the social spider Stegodyphus dumicola. Colonies engage in collective web buildi...
Genetic monogamy despite frequent extrapair copulations in "strictly monogamous" wild jackdaws [0.03%]
严格的单配制凤头鹦鹉鵙中频繁的婚外交配并未改变其基因层面仍然单配的事实

"Monogamy" refers to different components of pair exclusiveness: the social pair, sexual partners, and the genetic outcome of sexual encounters. Avian monogamy is usually defined socially or genetically, whereas quantifications of sexual be...

In response to anthropogenic noise, vertebrates express modified acoustic communication signals either through individual plasticity or local population adaptation. In contrast, how insects respond to this stressor is poorly studied. Field ...
