Circadian rhythmicity plays an important role for many aspects of honey bees' lives. However, the question whether it also affects learning and memory remained unanswered. To address this question, we studied the effect of circadian timing ...

Fitting generalised linear models (GLMs) with more than one predictor has become the standard method of analysis in evolutionary and behavioural research. Often, GLMs are used for exploratory data analysis, where one starts with a complex f...

The background noise generated in large social aggregations of calling individuals is a potent source of auditory masking for animals that communicate acoustically. Despite similarities with the so-called "cocktail-party problem" in humans,...

Analyses of the pattern of associations, social interactions, coalitions, and aggression among chacma baboons (Papio hamadryas ursinus) in the Okavango Delta of Botswana over a 16-year period indicate that adult females form close, equitabl...
Nonlinear effects of food aggregation on interference competition in mallards [0.03%]
食物聚合对绿头鸭干扰竞争的非线性效应

Previous studies of interference competition have shown an asymmetric effect on intake rate of foragers on clumped resources, with only subordinate individuals suffering. However, the food distributions in these studies were uniform or high...

MANY ANIMALS USE SIGNALS TO COMMUNICATE THEIR SOCIAL STATUS TO CONSPECIFICS, AND THE SOCIAL CONTROL HYPOTHESIS SUGGESTS THAT SOCIAL INTERACTIONS MAINTAIN THE EVOLUTIONARY STABILITY OF STATUS SIGNALS: low-quality individuals signal at a low ...

Although studies on the evolution and function of female ornaments have become more numerous in the last years, the majority of these studies were carried out in cases where female ornaments were a smaller and duller version of the ornament...

Engagement in extra-pair copulations is an example of the abundant conflicting interests between males and females over reproduction. Potential benefits for females and the risk of cuckoldry for males are expected to have important implicat...

Living in social groups facilitates cross-infection by parasites. However, empirical studies on indirect transmission within wildlife populations are scarce. We investigated whether asynchronous overnight refuge sharing among neighboring sl...
Bill color, not badge size, indicates testosterone-related information in house sparrows [0.03%]
家麻雀的睾丸素信息通过羽毛颜色而非胸脯标志来体现

The honesty of ornamental signals of quality is often argued to be enforced via costs associated with testosterone. It is still poorly understood, however, how seasonal variation of testosterone within individuals is related to the timing a...
