Science is meant to be the systematic and objective study of the world but evidence suggests that scientific practices are sometimes falling short of this expectation. In this invited idea, we argue that any failure to conduct research acco...
Who cares? Experimental attention biases provide new insights into a mammalian sexual signal [0.03%]
他关心谁？实验性注意偏向提供了哺乳动物性信号的新见解

The effects of intrasexual and intersexual selection on male trait evolution can be difficult to disentangle, especially based on observational data. Male-male competition can limit an observer's ability to identify the effect of female mat...
Task switching is associated with temporal delays in Temnothorax rugatulus ants [0.03%]
任务切换与rugatulus蚂蚁的时序延迟相关联

The major evolutionary transitions often result in reorganization of biological systems, and a component of such reorganization is that individuals within the system specialize on performing certain tasks, resulting in a division of labor. ...
Evolution of elaborate parental care: phenotypic and genetic correlations between parent and offspring traits [0.03%]
复杂亲代抚育行为的进化：亲代和子代性状的表型和基因相关性

Clare P Andrews
The evolution of elaborate forms of parental care is an important topic in behavioral ecology, yet the factors shaping the evolution of complex suites of parental and offspring traits are poorly understood. Here, we use a multivariate quant...
Exploration is dependent on reproductive state, not social state, in a cooperatively breeding bird [0.03%]
在合作繁殖的鸟类中，探索活动依赖于繁殖状态而非社会地位

Personality is an intriguing phenomenon in populations because it constrains behavioral flexibility. One theory suggests that personality could be generated and maintained if dependent on asset protection. It is predicted that trade-offs wi...
The benefits of being toxic to deter predators depends on prey body size [0.03%]
天敌捕食压力下猎物有毒性的益处取决于猎物的个体大小

Karen E Smith
Many prey have evolved toxins as a defense against predation. Those species that advertise their toxicity to would-be predators with conspicuous warning signals are known as "aposematic." Investment in toxicity by aposematically signaling p...
Adult helpers increase the recruitment of closely related offspring in the cooperatively breeding rifleman [0.03%]

Indirect fitness benefits gained through kin-selected helping are widely invoked to explain the evolution of cooperative breeding behavior in birds. However, the impact of helpers on productivity of helped broods can be difficult to determi...

The influence of coloration on the ecology and evolution of moving animals in groups is poorly understood. Animals in groups benefit from the "confusion effect," where predator attack success is reduced with increasing group size or density...
Sexually selected sentinels? Evidence of a role for intrasexual competition in sentinel behavior [0.03%]
警戒行为的性选择学说——竞争对警戒行为的作用机制的证据

Although the evolutionary mechanisms that favor investment in cooperative behaviors have long been a focus of research, comparatively few studies have considered the role that sexual selection may play. For example, evolutionary explanation...
Not leaving home: grandmothers and male dispersal in a duolocal human society [0.03%]
老不离家：双居人类社会中的祖母与男性迁移现象

Qiao-Qiao He et al.
Models suggest that dispersal patterns will influence age- and sex-dependent helping behavior in social species. Duolocal social systems (where neither sex disperses and mating is outside the group) are predicted to be associated with mothe...
