Choosing a mate is one of the most important decisions in an animal's lifetime. Female mate choice is often guided by the presence or intensity of male sexual ornaments, which must be integrated and compared among potential mates. Individua...
Acoustic and visual stimuli combined promote stronger responses to aerial predation in fish [0.03%]
声学和视觉刺激结合促进鱼类对空袭的更强反应

Bird predation poses a strong selection pressure on fish. Since birds must enter the water to catch fish, a combination of visual and mechano-acoustic cues (multimodal) characterize an immediate attack, while single cues (unimodal) may repr...
The effect of social environment on bird song: listener-specific expression of a sexual signal [0.03%]

Animal signals should consistently differ among individuals to convey distinguishable information about the signalers. However, behavioral display signals, such as bird song are also loaded with considerable within-individual variance with ...

Sexual selection is a key component of evolutionary biology. However, from the very formulation of sexual selection by Darwin, the nature and extent of sexual selection have been controversial. Recently, such controversy has led back to the...
Multiple constraints on urban bird communication: both abiotic and biotic noise shape songs in cities [0.03%]
城市鸟类交流受到多种限制：声音和生物噪音都塑造了城市中的鸟鸣叫声

Ambient noise can cause birds to adjust their songs to avoid masking. Most studies investigate responses to a single noise source (e.g., low-frequency traffic noise, or high-frequency insect noise). Here, we investigated the effects of both...
Olfactory cues of large carnivores modify red deer behavior and browsing intensity [0.03%]
大型食肉动物的嗅觉线索改变红鹿的行为和觅食强度

This study examined the effect of perceived predation risk imposed by lynx (Lynx lynx) and wolf (Canis lupus) on red deer (Cervus elaphus) foraging behavior under experimental conditions. We hypothesized that in response to large carnivore ...
Memory extinction and spontaneous recovery shaping parasitoid foraging behavior [0.03%]
记忆消退和自发恢复塑造寄生蜂的觅食行为

Animals can alter their foraging behavior through associative learning, where an encounter with an essential resource (e.g., food or a reproductive opportunity) is associated with nearby environmental cues (e.g., volatiles). This can subseq...
Song type and song type matching are important for joint territorial defense in a duetting songbird [0.03%]
鸣唱类型和鸣唱类型的匹配对于一对杜鸣鸟共同领土防御很重要

Amie Wheeldon et al.
Birds have a diverse acoustic communication system, with species-specific repertoires facilitating more complex behaviors in terms of both within- and between-pair communications. Certain song types are produced for specific functions, such...

Individuals differ in the quantity and quality of their associations with conspecifics. The resulting variation in the positions that individuals occupy within their social environment can affect several aspects of life history, including r...
Social and spatial conflict drive resident aggression toward outsiders in a group-living fish [0.03%]
社会和空间冲突驱动群居鱼对其它鱼类的攻击性行为

Jakob Gübel
Group-living animals often experience within-group competition for resources like shelter and space, as well as for social status. Because of this conflict, residents may aggressively resist joining attempts by new members. Here, we asked w...
