Postcopulatory sexual selection is associated with sperm aggregate quality in Peromyscus mice [0.03%]
交配后的性选择与白足鼠的精子聚集质量有关

In some species, sperm form coordinated groups that are hypothesized to improve their swimming performance in competitive contexts or to navigate through the viscous fluids of the female reproductive tract. Here we investigate sperm aggrega...
Social environment shapes female settlement decisions in a solitary carnivore [0.03%]
社会环境影响独居食肉动物的雌性定居决定
J E Hansen,A G Hertel,S C Frank et al.
J E Hansen et al.
How and where a female selects an area to settle and breed is of central importance in dispersal and population ecology as it governs range expansion and gene flow. Social structure and organization have been shown to influence settlement d...
An evolutionary model of sensitive periods when the reliability of cues varies across ontogeny [0.03%]
当信号的可靠性在个体发育过程中发生变化时的敏感期进化模型

Sensitive periods are widespread in nature, but their evolution is not well understood. Recent mathematical modeling has illuminated the conditions favoring the evolution of sensitive periods early in ontogeny. However, sensitive periods al...
Context-dependent coloration of prey and predator decision making in contrasting light environments [0.03%]
背景依赖的捕食者和猎物在不同光照环境下的决策作用
Ossi Nokelainen,Francisko de Moraes Rezende,Janne K Valkonen et al.
Ossi Nokelainen et al.
A big question in behavioral ecology is what drives diversity of color signals. One possible explanation is that environmental conditions, such as light environment, may alter visual signaling of prey, which could affect predator decision-m...
Emergence and repeatability of leadership and coordinated motion in fish shoals [0.03%]
鱼群领导力和协调运动的出现与重复性
Dimitra G Georgopoulou,Andrew J King,Rowan M Brown et al.
Dimitra G Georgopoulou et al.
Studies of self-organizing groups like schools of fish or flocks of birds have sought to uncover the behavioral rules individuals use (local-level interactions) to coordinate their motion (global-level patterns). However, empirical studies ...
Zebra finch song is a very short-range signal in the wild: evidence from an integrated approach [0.03%]
整合方法证明环颈斑胸草雀鸣唱在野外是极近程信号
Hugo Loning,Simon C Griffith,Marc Naguib
Hugo Loning
Birdsong is typically seen as a long-range signal functioning in mate attraction and territory defense. Among birds, the zebra finch is the prime model organism in bioacoustics, yet almost exclusively studied in the lab. In the wild, howeve...
Evidence for morph-specific substrate choice in a green-brown polymorphic grasshopper [0.03%]
绿色和棕色形态多态性蚱蜢特异性底物选择的证据
Pauline Heinze,Petra Dieker,Hannah M Rowland et al.
Pauline Heinze et al.
Orthopteran insects are characterized by high variability in body coloration, in particular featuring a widespread green-brown color polymorphism. The mechanisms that contribute to the maintenance of this apparently balanced polymorphism ar...
Carry on caring: infected females maintain their parental care despite high mortality [0.03%]
带病母亲继续照顾后代：高死亡率下仍旧坚持抚养行为
Tom Ratz,Katy M Monteith,Pedro F Vale et al.
Tom Ratz et al.
Parental care is a key component of an organism's reproductive strategy that is thought to trade-off with allocation toward immunity. Yet, it is unclear how caring parents respond to pathogens: do infected parents reduce care as a sickness ...
Social and physical environment independently affect oviposition decisions in Drosophila [0.03%]
果蝇的产卵决定受社会和物理环境的独立影响
Emily R Churchill,Calvin Dytham,Jon R Bridle et al.
Emily R Churchill et al.
In response to environmental stimuli, including variation in the presence of conspecifics, genotypes show highly plastic responses in behavioral and physiological traits influencing reproduction. Although extensively documented in males, su...
The influence of maternal glucocorticoids on offspring phenotype in high- and low-risk environments [0.03%]
高危和低风险环境下的母体糖皮质激素对后代表型的影响
Kirsty J MacLeod,Tracy Langkilde,Cameron P Venable et al.
Kirsty J MacLeod et al.
Elevated maternal glucocorticoid levels during gestation can lead to phenotypic changes in offspring via maternal effects. Although such effects have traditionally been considered maladaptive, maternally derived glucocorticoids may adaptive...
