Social structure can have significant effects on selection, affecting both individual fitness traits and population-level processes. As such, research into its dynamics and evolution has spiked in the last decade, where theoretical and comp...
Multilevel Bayesian analysis of monk parakeet contact calls shows dialects between European cities [0.03%]

Geographic differences in vocalizations provide strong evidence for animal culture, with patterns likely arising from generations of social learning and transmission. Most studies on the evolution of avian vocal variation have predominantly...
When parents play favorites: brood demand shapes parental preference for offspring UV color [0.03%]
当父母有所偏爱时：后代群体的需求决定了父母对后代UV颜色的偏好

Parents might initially produce more offspring than they might be able to raise. However, when offspring demand exceeds their parents´ rearing capacity, parents might shift care towards the offspring which yield greater fitness returns to ...

Cognitive flexibility can enhance the ability to adjust to changing environments. Here, we use learning simulations to investigate the possible advantages of flexible learning in volatile (changing) environments. We compare two established ...

Higher male:female operational sex ratio (OSR) is often assumed to lead to stronger sexual selection on males. Yet, this premise has been directly tested by very few studies, with mixed outcomes. We investigated how OSR affects the strength...
Machine learning reveals singing rhythms of male Pacific field crickets are clock controlled [0.03%]
机器学习揭示雄性太平洋郊蟋蟀的鸣唱节奏受生物钟控制

Circadian rhythms are ubiquitous in nature and endogenous circadian clocks drive the daily expression of many fitness-related behaviors. However, little is known about whether such traits are targets of selection imposed by natural enemies....
Peregrine falcons shift mean and variance in provisioning in response to increasing brood demand [0.03%]
游隼根据后代需求的增加相应地调整觅食供给的均值和方差

Rebekah A McKinnon et al.
The hierarchical model of provisioning posits that parents employ a strategic, sequential use of three provisioning tactics as offspring demand increases (e.g., due to increasing brood size and age). Namely, increasing delivery rate (reduci...
Grow up, be persistent, and stay focused: keys for solving foraging problems by free-ranging possums [0.03%]

Individuals within a species often vary in both their problem-solving approach and ability, affecting their capacity to access novel food resources. Testing problem-solving in free-ranging individuals is crucial for understanding the fundam...

Animals that communicate by acoustic signaling share a common acoustic environment. Birds are particularly vocal examples, using a wide repertoire of broadcast signals for mate attraction and territorial defense. However, interference cause...
Sex-specific effects of psychoactive pollution on behavioral individuality and plasticity in fish [0.03%]
psychoactive污染的性别特异性影响对鱼的行为独特性和适应性的影響
