Individual behavior varies for many reasons, but how early in life are such differences apparent, and are they under selection? We investigated variation in early-life behavior in a wild eastern gray kangaroo (Macropus giganteus) population...
Lack of intergenerational reproductive conflict, rather than lack of inclusive fitness benefits, explains absence of post-reproductive lifespan in long-finned pilot whales [0.03%]
缺乏代际生殖冲突而非缺乏包容性适应度利益解释了长吻飞旋 dolphins缺乏生殖后寿命的现象

Life-history theory suggests that individuals should reproduce until death, yet females of a small number of mammals live for a significant period after ceasing reproduction, a phenomenon known as post-reproductive lifespan. It is thought t...
Food supply and provisioning behavior of parents: Are small hoopoe nestlings condemned to die? [0.03%]
食物供给与亲鸟的觅食行为：小小的戴胜雏鸟注定要死亡吗？

Parents might use signals of need or of quality to decide food provisioning among their offspring, while the use of one or another signal might depend on food availability. Begging success of nestlings of different quality (i.e., body size)...

Parasite-induced modification of host behavior increasing transmission to a next host is a common phenomenon. However, field-based studies are rare, and the role of environmental factors in eliciting host behavioral modification is often no...

In many social species, both the acquisition of dominance and the duration that individuals maintain their status are important determinants of breeding tenure and lifetime reproductive success. However, few studies have yet examined the ex...
Condition dependence of (un)predictability in escape behavior of a grasshopper species [0.03%]

(Un)predictability has only recently been recognized as an important dimension of animal behavior. Currently, we neither know if (un)predictability encompasses one or multiple traits nor how (un)predictability is dependent on individual con...

Iridescence is a taxonomically widespread form of structural coloration that produces often intense hues that change with the angle of viewing. Its role as a signal has been investigated in multiple species, but recently, and counter-intuit...

Quantifying fitness is important to understand adaptive evolution. Reproductive values are useful for making fitness comparisons involving different categories of individuals, like males and females. By definition, the reproductive value of...
To eat, or not to eat: a phantom decoy affects information-gathering behavior by a free-ranging mammalian herbivore [0.03%]
吃还是不吃：感觉中的幻影对自由活动的草食性哺乳动物获取信息的行为有影响

When foraging, making appropriate food choices is crucial to an animal's fitness. Classic foraging ecology theories assume animals choose food of greatest benefit based on their absolute value across multiple dimensions. Consequently, poore...
Dazzled by shine: gloss as an antipredator strategy in fast moving prey [0.03%]
闪耀背后的玄机——会发光的猎物如何迷惑天敌

Patricia Henríquez-Piskulich et al.
Previous studies on stationary prey have found mixed results for the role of a glossy appearance in predator avoidance-some have found that glossiness can act as warning coloration or improve camouflage, whereas others detected no survival ...
