Abstract: Food sharing is relatively widespread across the animal kingdom, but research into the socio-ecological factors affecting this activity has predominantly focused on primates. These studies do suggest though that...
Punish the thief-coevolution of defense and cautiousness stabilizes ownership [0.03%]
惩罚窃贼：防御和谨慎的协同进化稳定了财产所有权
Martin Hinsch,Jan Komdeur
Martin Hinsch
Abstract: Ownership of non-controllable resources usually has to be maintained by costly defense against competitors. Whether defense and thus ownership pays in terms of fitness depends on its effectiveness in preventing ...
Conflict over non-partitioned resources may explain between-species differences in declines: the anthropogenic competition hypothesis [0.03%]
人为竞争假说可以解释物种差异化的下降趋势：非划分资源的竞争作用
Andrew D Higginson
Andrew D Higginson
Abstract: Human alterations of habitats are causing declines in many species worldwide. The extent of declines varies greatly among closely related species, for often unknown reasons that must be understood in order to ma...
Wild chimpanzees' use of single and combined vocal and gestural signals [0.03%]
野生黑猩猩单一声势信号和复合声势信号的使用

Abstract: We describe the individual and combined use of vocalizations and gestures in wild chimpanzees. The rate of gesturing peaked in infancy and, with the exception of the alpha male, decreased again in older age grou...
Adult bacterial exposure increases behavioral variation and drives higher repeatability in field crickets [0.03%]
幼体暴露于细菌中增加了田野蟋蟀的行为多样性并提高了其重复性
Nicholas DiRienzo,Petri T Niemelä,Ann V Hedrick et al.
Nicholas DiRienzo et al.
Among-individual differences in behavior are now a widely studied research-focus within the field of behavioral ecology. Furthermore, elements of an animal's internal state, such as energy or fat reserves, and infection status can have larg...
Sex in murky waters: algal-induced turbidity increases sexual selection in pipefish [0.03%]
鱼藻缠绕：水生植物通过增加雌性竞争来增强鱼类的性选择
Josefin Sundin,Tonje Aronsen,Gunilla Rosenqvist et al.
Josefin Sundin et al.
Abstract: Algal-induced turbidity has been shown to alter several important aspects of reproduction and sexual selection. However, while turbidity has been shown to negatively affect reproduction and sexually selected tra...
Silence is not golden: the hissing calls of tits affect the behaviour of a nest predator [0.03%]
叫声不止黄金尽：䴓科鸟类的嘶嘶声影响着一种巢穴捕食者的行为
Karol Zub,Dorota Czeszczewik,Ireneusz Ruczyński et al.
Karol Zub et al.
Abstract: Nest predation is one of the most important mortality factors of birds. Field observations showed that tits (Paridae) produce hissing calls and, usually, have lower breeding losses than nesting Ficedula flycatch...
Long-term analysis on the variance of extra-group paternities in rhesus macaques [0.03%]
长期分析恒河猴窝外父本变异系数
Angelina V Ruiz-Lambides,Brigitte M Weiß,Lars Kulik et al.
Angelina V Ruiz-Lambides et al.
Abstract: Extra-group paternity (EGP) has been described in various mammalian species; however, little is known about which factors contribute to the variation in EGP, as the majority of studies were restricted in time an...
Predatory interactions between prey affect patch selection by predators [0.03%]
猎物间的捕食相互作用影响捕食者的取食选择
Yasuyuki Choh,Maurice W Sabelis,Arne Janssen
Yasuyuki Choh
Abstract: When predators can use several prey species as food sources, they are known to select prey according to foraging efficiency and food quality. However, interactions between the prey species may also affect prey c...
Evidence against observational spatial memory for cache locations of conspecifics in marsh tits Poecile palustris [0.03%]
缺乏关于绿头鸦观测性空间记忆的证据
A Utku Urhan,Ellen Emilsson,Anders Brodin
A Utku Urhan
Abstract: Many species in the family Paridae, such as marsh tits Poecile palustris, are large-scale scatter hoarders of food that make cryptic caches and disperse these in large year-round territories. The perhaps most we...
