No evidence for innate differences in tadpole behavior between natural, urbanized, and invasive populations [0.03%]
自然种群、城市种群和入侵种群蛙蝌蚪行为的先天差异并无实证支持

Max Mühlenhaupt et al.
Abstract: Animals are increasingly challenged to respond to novel or rapidly changing habitats due to urbanization and/or displacement outside their native range by humans. Behavioral differences, such as increased boldne...
Evolution of Boldness and Exploratory Behavior in Giant Mice from Gough Island [0.03%]

Island populations are hallmarks of extreme phenotypic evolution. Radical changes in resource availability and predation risk accompanying island colonization drive changes in behavior, which Darwin likened to tameness in domesticated anima...
How territoriality reduces disease transmission among social insect colonies [0.03%]
领地性如何减少社会性昆虫群落间的疾病传播

Natalie Lemanski et al.
Abstract: Social behavior can have a major impact on the dynamics of infectious disease outbreaks. For animals that live in dense social groups, such as the eusocial insects, pathogens pose an especially large risk becaus...
Group size and modularity interact to shape the spread of infection and information through animal societies [0.03%]
群体大小和模块化相互作用以塑造感染和信息通过动物社会传播的方式

Social interactions between animals can provide many benefits, including the ability to gain useful environmental information through social learning. However, these social contacts can also facilitate the transmission of infectious disease...
Brighter is better: bill fluorescence increases social attraction in a colonial seabird and reveals a potential link with foraging [0.03%]
更强的荧光效果更好：殖民海鸟的求偶行为中鸟喙荧光效果增强社会吸引力并可能与觅食存在某种联系

Crested auklets (Aethia cristatella) are colonial seabirds with brilliant orange bills during the breeding season. We characterized the bill pigment with spectroscopy methods (resonance Raman, fluorescence, absorbance). We excluded caroteno...
Dissecting the two mechanisms of scramble competition among the Virunga mountain gorillas [0.03%]
解析维龙加山地大猩猩之间两种混乱竞争机制
Andrew M Robbins,Cyril C Grueter,Didier Abavandimwe et al.
Andrew M Robbins et al.
Abstract: Two mechanisms have been proposed to explain why scramble competition can increase the travel requirements of individuals within larger groups. Firstly, individuals in larger groups may be more likely to encount...
The development and maintenance of sex differences in dietary breadth and complexity in Bornean orangutans [0.03%]
婆罗洲猩猩饮食范围和复杂性的性别差异的发展和维持
Caroline Schuppli,S Suci Utami Atmoko,Erin R Vogel et al.
Caroline Schuppli et al.
Abstract: Orangutans show a pronounced sexual dimorphism, with flanged males (i.e., males with fully grown secondary sexual characteristics) reaching twice the size of adult females. Furthermore, adult orangutans show sex...
Egg covering in cavity nesting birds may prevent nest usurpation by other species [0.03%]
腔巢鸟类的蛋覆盖行为可以防止其他物种侵占鸟巢
Tore Slagsvold,Karen L Wiebe
Tore Slagsvold
Abstract: Some birds cover their eggs with nest material when they leave to forage. It has been suggested that such egg-covering aids thermoregulation or prevents predation but here we present a new hypothesis, that secon...
A resource-poor developmental diet reduces adult aggression in male Drosophila melanogaster [0.03%]
资源匮乏的发育饮食降低雄性黑腹果蝇成虫的攻击性

Aggressive behaviours occur throughout the animal kingdom and agonistic contests often govern access to resources. Nutrition experienced during development has the potential to influence aggressive behaviours in adults through effects on gr...

Parasites and their social hosts form many different relationships. But what kind of selection regimes are important? A look at the parameters that determine fitness of the two parties suggests that social hosts differ from solitary ones pr...
