Dynamic color change in the grouper Variola louti during interspecific interactions and swimming [0.03%]
石斑鱼(Variola louti)在种间相互作用和游泳过程中的动态色彩变化

Sagi Marom et al.
Animals can change their body color for various ecological functions. In fish, rapid dynamic color change is primarily known in contexts of intraspecific communication and camouflage, while examples in interspecific contexts are rare. We st...
Reproduction is driven by seasonal environmental variation in an equatorial mammal, the banded mongoose (Mungos mungo) [0.03%]
季节性环境变化驱动赤道哺乳动物——带纹mongooses(Mungos mungo)的繁殖

Reproduction is an energetically costly activity and so is often timed to occur when conditions are most favorable. However, human-induced changes in long-term, seasonal, and short-term climatic conditions have imposed negative consequences...

Behavioral outcomes, including foraging efficiency and reproductive success, often improve with age and with repeated breeding attempts. Here we examined the role of previous experience on the nest-building behavior of wild blue tits Cyanis...
Territorial-sneaker games with non-uniform interactions and female mate choice [0.03%]
非均匀相互作用下的领地运动、 sneakers行为及雌性配偶选择效应
Thomas N Sherratt,Christopher D Beatty,Ian Dewan et al.
Thomas N Sherratt et al.
Male territorial-sneaker polymorphisms are common in nature. To understand how these polymorphisms evolve, we developed a game theoretical model analogous to the classical Hawk-Dove model, but with two important differences. First, we allow...
Experimental support for partial compensation, not matched, partner response rules in blue tits [0.03%]
实验支持大山雀不匹配的伴侣反应规则的部分补偿理论

Aisha C Bründl et al.
Outcomes of theoretical models on conflict resolution between investing partners in bi-parental care systems typically predict "partial compensation" or "matched" response rules, depending on underlying assumptions. Further, although experi...
No evidence for phenotypic condition-dependent ejaculate allocation in response to sperm competition in a seed beetle [0.03%]
没有证据显示一种种子甲虫会对精子竞争做出适应性特征条件的配子分配反应
Blake W Wyber,Joseph L Tomkins,Leigh W Simmons
Blake W Wyber
Sperm competition is known to favor the evolution of male traits that confer an advantage in gaining fertilizations when females mate multiply. Ejaculate production can be costly and the strategic allocation of sperm in relation to the sper...
Effects of experimental nest treatment with herbs on ectoparasites and body condition of nestlings [0.03%]
药用植物对巢穴处理的实验效果及其对雏鸟体内外寄生虫和体质的影响研究

Nest fumigation behavior involves the incorporation of fresh green plant fragments that contain ectoparasite-repellent volatile compounds into birds' nests. This behavior is relatively rare among bird species, and there is ongoing debate ab...

To avoid potentially noxious prey, predators need to discriminate between palatable and unpalatable prey species. Unpalatable prey often exhibits visual warning signals, which can consist of multiple components, such as color and pattern. A...
A reinvestigation of cognitive styles in sticklebacks: decision success varies with behavioral type [0.03%]
三刺鱼认知风格的再研究：决策成功因行为类型而异
Nick A R Jones,Kirstin Gaffney,Giacomo Gardella et al.
Nick A R Jones et al.
The "cognitive styles" hypothesis suggests that individual differences in behavior are associated with variation in cognitive performance via underlying speed-accuracy trade-offs. While this is supported, in part, by a growing body of evide...
Responses in adult pied flycatcher males depend on playback song similarity to local population [0.03%]
成年黑顶伯劳雄鸟的反应取决于播放歌曲与当地种群的相似性
Mario Gallego-Abenza,Fanny-Linn H Kraft,Lan Ma et al.
Mario Gallego-Abenza et al.
Song divergence driven by social learning has been proposed to be a key factor driving allopatric speciation in oscine birds. Songbirds often respond more to songs deriving from their local population, suggesting the potential for acoustic ...
