Populations of animals are composed of individuals that differ in ecologically relevant behaviors. Building evidence also suggests that individuals occupy different social niches. Here, in a mark-recapture experiment, we show evidence of an...
Testosterone, signal coloration, and signal color perception in male zebra finch contests [0.03%]
睾酮、信号颜色和斑马 Finch雄性争斗中的信号色彩感知

Many animals use assessment signals to resolve contests over limited resources while minimizing the costs of those contests. The carotenoid-based orange to red bills of male zebra finches (Taeniopygia guttata) are thought to function as ass...
Effects of a COVID-19 lockdown-induced pause and resumption of artificial provisioning on blacktip reef sharks (Carcharhinus melanopterus) and pink whiprays (Pateobatis fai) in French Polynesia (East-Pacific) [0.03%]

The tourism activities linked to artificial provisioning of blacktip reef sharks (Carcharhinus melanopterus) and pink whiprays (Pateobatis fai) on a specific site in French Polynesia were suddenly and completely stopped due to a COVID-19 lo...
Breeder aggression does not predict current or future cooperative group formation in a cooperatively breeding bird [0.03%]
育种攻击性并不能预测合作群的当前或未来形成情况——以一种合作育种鸟类为例

In cooperatively breeding species, subordinates forgo reproduction to assist breeders in raising offspring. When cooperative breeding is facultative, breeders from the same population may differ in whether they are assisted by non-breeding ...
No Correlation Between Three Selected Trade-Offs in Birdsong Performance and Male Quality for a Species With Song Repertoires [0.03%]
鸣鸟类歌声表现的三个特征 trade-off 与雄鸟质量无关

Gonçalo C Cardoso et al.
Demanding performance of vocal signals, such as birdsong, may be evaluated by trade-offs among acoustic traits. If individuals differ in their ability to sustain physiologically demanding singing, then aspects of song performance resulting ...

Crows and other birds in the family Corvidae regularly share information to learn the identity and whereabouts of dangerous predators, but can they use social learning to solve a novel task for a food reward? Here we examined the factors af...

Although the rattling of rattlesnakes (Crotalus and Sistrurus) is widely accepted as being aposematic, the hypothesis that rattling deters approach from the snake's potentially dangerous adversaries has not been well tested. In a controlled...
Behaviour before beauty: signal weighting during mate selection in the butterfly Papilio polytes [0.03%]
行为重于颜值：帕布里奥蝴蝶择偶时的信号权重问题研究
Erica L Westerman,Nicholas Antonson,Sydney Kreutzmann et al.
Erica L Westerman et al.
Mating displays often contain multiple signals. Different combinations of these signals may be equally successful at attracting a mate, as environment and signal combination may influence relative signal weighting by choosy individuals. Thi...

Behavior courses face numerous challenges when moving to an online environment, as has been made necessary by the COVID-19 pandemic. These challenges occur largely because behavior courses, like most organismal biology courses, often stress...
Predator-induced selection on urchin activity level depends on urchin body size [0.03%]
海胆的体型决定了逃避捕食者的能力
Justin Pretorius,James L L Lichtenstein,Erika J Eliason et al.
Justin Pretorius et al.
Temporally consistent individual differences in behavior impact many ecological processes. We simultaneously examined the effects of individual variation in prey activity level, covering behavior, and body size on prey survival with predato...
