The evolution of mating systems reflects a balance of the often-conflicting interests of males and females. Polygyny, a mating system in which males have multiple mates, presents a fitness benefit to males, but the consequences for females ...
An immune challenge induces a decline in parental effort and compensation by the mate [0.03%]

Immune defense is fundamental to diminish the negative effects of the attack of infectious agents, yet the activation of the immune system entails costs and may compromise other life-history traits such as reproduction. In reproductive brow...
Urban sensory conditions alter rival interactions and mate choice in urban and forest túngara frogs [0.03%]

Sexual communication often takes place in networks with multiple competing signalers being simultaneously assessed by mate choosers. Altered sensory conditions, such as noise and light pollution, can affect communication by altering signal ...
Clutch attendance and call parameters are linked to mating success in a glassfrog with paternal care [0.03%]
雄性照顾与抱对成功率有关的树蛙科青蛙的附着出席率和呼叫参数之间的关系

Females of some species improve their reproductive success not only by being choosy and selecting males with certain traits, but also by sequentially mating with multiple males within one reproductive season. However, it is relatively unkno...
Social and seasonal variation in dwarf mongoose home-range size, daily movements, and burrow use [0.03%]
社会和季节变化对矮 Mongooses 领域大小、日常迁移及巢穴使用的影响

When making decisions about resource use, social species must integrate not only environmental factors but also the influence of opportunities and costs associated with group living. Bigger groups are expected to move further and to need ac...
Detectability of a poison frog and its Batesian mimic depends on body posture and viewing angle [0.03%]
毒蛙及其贝茨拟态依靠身体姿态和观察角度来被察觉

Aposematic signals warn predators that prey should be avoided due to dangerous secondary defences. However, as warning signals do not always produce avoidance, warning colors may evolve as a trade-off balancing detectability against signal ...
Interaction between anthropogenic stressors affects antipredator defense in an intertidal crustacean [0.03%]
人为胁迫相互作用影响潮间带甲壳动物的御敌行为

The marine environment is increasingly subject to changes driven by anthropogenic stressors which may alter species' key behaviors and impact phenotypic plasticity. Such stressors rarely occur in isolation, yet our understanding of how simu...
Age, sex, and temperature shape off-territory feeder use in black-capped chickadees [0.03%]
黑顶 Chickadee 的年龄、性别和温度决定了它们的领地外觅食行为

Spatial ecology tends to focus on average movement patterns within animal groups; however, recent studies highlight the value of considering movement decisions both within and among individuals. We used a marked population of black-capped c...
Acoustic effects complement visual displays of Great Bowerbird bowers [0.03%]
大bower鸟的巢穴 acoustic效果补充了视觉展示

John A Endler et al.
Sexual selection can result in extreme development of multimodal mate-attracting traits, including complex constructions. Male Great Bowerbirds build bowers for attracting females. Bowers contain a thatched twig tunnel (avenue) opening onto...

Principles of social evolution have long been used retrospectively to interpret social interactions, but have less commonly been applied predictively to inform conservation and animal husbandry strategies. We investigate whether differences...
