Neighbors affect vocal behavior of tropical wrens: a multispeaker density-manipulation experiment [0.03%]
邻域个体影响热带园丁鸟的鸣唱行为——一项多发声源密度操控实验研究

For territorial animals, the behavior of conspecific neighbors sets the social context of communication. Despite numerous investigations of vocalizations related to territory defense and mate attraction, the effect of neighbor density on an...
A test of the mechanistic process behind the convergent agonistic character displacement hypothesis [0.03%]
检验趋同攻击特征位移假说背后的机制过程的实验研究

In this era of rapid global change, understanding the mechanisms that enable or prevent species from co-occurring has assumed new urgency. The convergent agonistic character displacement (CACD) hypothesis posits that signal similarity enabl...
Limited evidence of biased offspring sex allocation in a cavity-nesting conspecific brood parasite [0.03%]
关于一种巢寄生鸟类子代性别比偏移的有限证据
Caitlin P Wells,Bruce E Lyon,Caroline M Thow et al.
Caitlin P Wells et al.
Sex allocation theory predicts that mothers should bias investment in offspring toward the sex that yields higher fitness returns; one such bias may be a skewed offspring sex ratio. Sex allocation is well-studied in birds with cooperative b...
Background selection for camouflage shifts in accordance with color change in an intertidal prawn [0.03%]
潮间带虾的伪装背景选择会随着其颜色变化而改变

To maximize camouflage across visually heterogeneous habitats, animals have evolved a variety of strategies, including polyphenism, color change, and behavioral background matching. Despite the expected importance of behavioral processes fo...
No geographical differences in male mate choice in a widespread fish, Limia perugiae [0.03%]
丽鱼科鱼类Limia perugiae 广布种中雄性配偶选择无地理差异

Chance Powell
Behavior, like most other traits, can have a spatial component, and variability of behavior at the population level is predicted. In this article, we explore male mate choice at this level. Male mate choice, while maybe not as common as fem...
Lunar synchrony, geography, and individual clocks shape autumn migration timing in an avian migrant [0.03%]
月相、地理和生物钟共同塑造一只候鸟的秋季迁徙时间
Alicia M Korpach,Christina M Davy,Alex M Mills et al.
Alicia M Korpach et al.
Timing programs in animal migrants have been selected to synchronize movements that coincide with predictable resources on the breeding and nonbreeding grounds. Migrants face potential temporal conflicts if their migration schedules benefit...
Relationship between dominance hierarchy steepness and rank-relatedness of benefits in primates [0.03%]
优势等级陡峭度与灵长类动物地位效益的相关性关系
Pengzhen Huang,Malgorzata E Arlet,Krishna N Balasubramaniam et al.
Pengzhen Huang et al.
In animal social groups, the extent to which individuals consistently win agonistic interactions and their ability to monopolize resources represent 2 core aspects of their competitive regime. However, whether these two aspects are closely ...
The scent of offspring: chemical profiles of larvae change during development and affect parental behavior in a burying beetle [0.03%]
后代的气味：金针虫幼体的化学特征在发育过程中发生变化并影响其亲代行为
Jacqueline Sahm,Beatrice Brobeil,Eric Grubmüller et al.
Jacqueline Sahm et al.
Chemical cues and signals, especially in insects, play a pivotal role in mediating interactions between individuals. Past studies have largely focused on adult semiochemicals and have neglected those of juvenile stages. Especially in the co...
Highly defended nudibranchs "escape" to visually distinct background habitats [0.03%]
高度防御性的海牛蝓会前往视觉上区别明显的栖息地以"逃生"
Cedric P van den Berg,Matteo Santon,John A Endler et al.
Cedric P van den Berg et al.
The "escape and radiate" hypothesis predicts that once species have evolved aposematism, defended species can utilize more visually diverse visual backgrounds as they "escape" the need to be well camouflaged. This enables species to explore...
Influence of visual information on sniffing behavior in a routinely trichromatic primate [0.03%]
视觉信息对一种常态三色视觉的灵长类动物嗅探行为的影响
Brigitte M Weiß,Anja Widdig
Brigitte M Weiß
Most catarrhine primates are considered to be strongly visually oriented, obtaining information about conspecifics and their environment from a diversity of visual cues. Other sensory modalities may provide information that is redundant and...
