To maximize their fitness, animals must often discriminate between stimuli differing in magnitude (such as size, intensity, or number). Weber's Law of proportional processing states that stimuli are compared based on the proportional differ...
Not all who wander are lost: prospecting and settlement of male floaters in the spotless starling [0.03%]
寻寻觅觅终有时：小斑尾林鸽独行雄的求偶流浪与定居策略研究
Iraida Redondo,Roger Fusté,Jaime Muriel et al.
Iraida Redondo et al.
Floaters are non-breeding individuals that lack a territory or a breeding site. In many species, they can be seen visiting the territories of conspecifics before obtaining their own breeding site. Prospecting behavior is hypothesized to ben...
Ecological contexts shape sexual selection on male color morphs in wood tiger moths [0.03%]
生态背景影响虎斑天蚕蛾雄性色型的性选择
Eetu Selenius,Chiara De Pasqual,Matleena Hänninen et al.
Eetu Selenius et al.
Color polymorphisms in natural populations often reflect the interplay between various selective pressures, such as natural and sexual selection. In this study, we investigate the dynamics of sexual selection operating on color polymorphism...
Patterns and drivers of female extra-pair mating in wild Kalahari meerkats [0.03%]
喀拉哈里草原裸狐猴雌性的额外配对模式及驱动因素
Annika Herdtle,Chris Duncan,Marta B Manser et al.
Annika Herdtle et al.
In many pair-living vertebrates, females commonly mate outside the pair bond, but when and why they do so is unclear. This behavior may stem from females seeking "good genes" or "compatible genes" from extra-pair mates superior to or less r...
Life expectancy in ants explains variation in helpfulness regardless of phylogenetic relatedness [0.03%]
蚂蚁的预期寿命解释了无论亲缘关系如何蚂蚁乐于助人的变化

Filip Turza et al.
Rescue behavior aims to free a relative from danger. Ants are particularly known for such helpfulness and, perhaps not coincidentally, also show the highest level of social organization in the animal kingdom, i.e. eusociality. However, even...
Silver spoons, reproduction, and growth catch-up in eastern Grey kangaroos [0.03%]
袋鼠的发育补偿机制及繁殖与银勺效应（以东灰大袋鼠为例）

Early growth and environmental conditions can shape life-history trajectories. Long-lived iteroparous species with indeterminate growth face growth-reproduction trade-offs for most of their lives. Poor early conditions can delay primiparity...
Synchronising anti-predator behavior in the red flour beetle Tribolium castaneum [0.03%]
红麦麸皮虫（Tribolium castaneum）的防掠行为的同步化
Kentarou Matsumura

In many animals, a phenomenon is often observed in which behavior depends on population density and many individuals within the group synchronize their state of behavior to some extent, and theoretical studies have suggested that this synch...
Human-induced pheromone pollution leads to changes in alternative mating tactics of moths [0.03%]
人为引起的信息素污染导致飞蛾的替代交配策略发生变化
Shevy Waner Rips,Michal Motro,Uzi Motro et al.
Shevy Waner Rips et al.
Environmental changes driven by anthropogenic activities often disrupt animal communication and mating behavior. Consequently, these changes may force animals to adopt alternative mating tactics and strategies to find a mate. The mating dis...
Social security: individuals in socially reciprocal groups may perceive security from predators [0.03%]
社会安全：在相互关联的社会群体中的个体可能感知到来自捕食者的安全
Conner S Philson,Clara Klassen,Kenta Uchida et al.
Conner S Philson et al.
One of the most explored factors mediating antipredator behavior is group size, which generally predicts individuals in larger social groups allocate less time to antipredator vigilance while foraging. However, group size alone does not cap...
Prey or protection? Access to food alters individual responses to competition in black widow spiders [0.03%]
捕食还是保护？食物的获得改变黑寡妇蜘蛛对竞争的个体反应
Tom Ratz,Pierre-Olivier Montiglio
Tom Ratz
Animals influence the phenotype and reproductive success of their conspecifics through competitive interactions. Such effects of competition can alter the intensity of selection and ultimately change the rate of evolution. However, the magn...
