Flexible compensation of uniparental care: female poison frogs take over when males disappear [0.03%]
灵活的单亲护理补偿：当雄性消失时，雌性毒蛙会接手

Parental care systems are shaped by costs and benefits to each sex of investing into current versus future progeny. Flexible compensatory parental care is mainly known in biparental species, particularly where parental desertion or reductio...
Rival male chemical cues evoke changes in male pre- and post-copulatory investment in a flour beetle [0.03%]
雄性化学线索诱发储粮甲虫的雌性和雄性交配前和交配后的适应性变异

Males can gather information on the risk and intensity of sperm competition from their social environment. Recent studies have implicated chemosensory cues, for instance cuticular hydrocarbons (CHCs) in insects, as a key source of this info...

Investigating patterns of among and within-individual trait variation in populations is essential to understanding how selection shapes phenotypes. Behavior is often the most flexible aspect of the phenotype, and to understand how it is aff...

Many animals communicate through acoustic signaling, and "acoustic space" may be viewed as a limited resource that organisms compete for. If acoustic signals overlap, the information in them is masked, so there should be selection toward st...

In socially monogamous species, in which both sexes provide essential parental care, males as well as females are expected to be choosy. Whereas hundreds of studies have examined monogamy in biparental birds, only several such studies exist...
A larger brain confers a benefit in a spatial mate search learning task in male guppies [0.03%]
较大的大脑在雄性孔雀鱼空间求偶搜索学习任务中具有优势

Brain size varies dramatically among vertebrates, and selection for increased cognitive abilities is thought to be the key force underlying the evolution of a large brain. Indeed, numerous comparative studies suggest positive relationships ...
Populations, pools, and peccaries: simulating the impact of ecosystem engineers on rainforest frogs [0.03%]
关于生态系统工程师对雨林青蛙影响的模拟：人口、资源和墨西哥白唇猯

"Ecosystem engineering" describes habitat alteration by an organism that affects another organism; such nontrophic interactions between organisms are a current focus in ecological research. Our study quantifies the actual impact an ecosyste...
Cortisol in mother's milk across lactation reflects maternal life history and predicts infant temperament [0.03%]
产后妈妈母乳中的皮质醇水平体现其生活史特征并影响婴儿性格形成
Katie Hinde,Amy L Skibiel,Alison B Foster et al.
Katie Hinde et al.
The maternal environment exerts important influences on offspring mass/growth, metabolism, reproduction, neurobiology, immune function, and behavior among birds, insects, reptiles, fish, and mammals. For mammals, mother's milk is an importa...
Effects of age, size, and mating history on sex role decision of a simultaneous hermaphrodite [0.03%]
年龄、大小和交配史对两性同体动物同时hermaphrodite性别角色决定的影响
Yumi Nakadera,Elferra M Swart,Jeroen P A Maas et al.
Yumi Nakadera et al.
Contrasting with separate-sexed animals, simultaneous hermaphrodites display unique reproductive strategies as they are male and female at the same time. Simultaneous hermaphrodites that copulate unilaterally, for instance, make a decision ...
Biparental incubation-scheduling: no experimental evidence for major energetic constraints [0.03%]
双亲孵卵的换孵调度：没有实验表明主要的能量限制作用
Martin Bulla,Will Cresswell,Anne L Rutten et al.
Martin Bulla et al.
Incubation is energetically demanding, but it is debated whether these demands constrain incubation-scheduling (i.e., the length, constancy, and timing of incubation bouts) in cases where both parents incubate. Using 2 methods, we experimen...
