In many species, females have evolved behavioral strategies to reduce the risk of infanticide. For instance, polyandry can create paternity confusion that inhibits males from killing offspring they could have sired. Here, the authors propos...

How do territorial neighbors resolve the location of their boundaries? We addressed this question by testing the predictions of 2 nonexclusive game theoretical models for competitive signaling: the sequential assessment game and the territo...

Throughout their recent recovery in several industrialized countries, large carnivores have had to cope with a changed landscape dominated by human infrastructure. Population growth depends on the ability of individuals to adapt to these ch...

Desiccation is a particular risk for small animals in arid environments. In response, many organisms "construct niches," favorable microenvironments where they spend part or all of their life cycle. Some maintain such environments for their...
Wall lizards display conspicuous signals to conspecifics and reduce detection by avian predators [0.03%]
壁虎通过向同类展示醒目的信号并减少被鸟类捕食者发现的几率来吸引注意

Visual signals are often under conflicting selection to be hidden from predators while being conspicuous to mates and rivals. Here, we investigated whether 3 different island populations of Aegean wall lizards (Podarcis erhardii) with varia...
Resource redistribution in polydomous ant nest networks: local or global? [0.03%]
多巢网络蚂蚁窝内的资源再分配：局部的还是全局的？

An important problem facing organisms in a heterogeneous environment is how to redistribute resources to where they are required. This is particularly complex in social insect societies as resources have to be moved both from the environmen...

Premature loss of offspring decreases direct fitness of parents. In gregarious mammals, both ecological and social variables impact offspring survival and may interact with each other in this regard. Although a number of studies have invest...
Foraging for carotenoids: do colorful male hihi target carotenoid-rich foods in the wild? [0.03%]
觅食胡萝卜素吗？野生雄性绯红短尾鸟以富含胡萝卜素的食物为目标吗？

Dietary access to carotenoids is expected to determine the strength of carotenoid-based signal expression and potentially to maintain signal honesty. Species that display carotenoid-based yellow, orange, or red plumage are therefore expecte...
Vocal fundamental and formant frequencies are honest signals of threat potential in peripubertal males [0.03%]
青春期男孩的发声基础频率和共振峰频率是体现威胁程度的诚实信号

Carolyn R Hodges-Simeon et al.
Fundamental and formant frequencies influence perceived pitch and are sexually dimorphic in humans. The information content of these acoustic parameters can illuminate the forces of sexual selection shaping vocal sex differences as well as ...
Variance in male lifetime reproductive success and estimation of the degree of polygyny in a primate [0.03%]

The degree of polygyny is predicted to influence the strength of direct male-male competition, leading to a high variance in male lifetime reproductive success and to reproduction limited to the prime period of adulthood. Here, we explore t...
