Sex-specific immunocompetence: resistance and tolerance can both be futile but not under the same circumstances [0.03%]
性别特异的免疫能力：抵抗力和耐受力在不同情境下都会变得无力

Immunocompetence evolution can involve a "resistance is futile" scenario if parasite encounter rates are so high that high investment in resistance only marginally delays infection. Here, we investigate two understudied aspects of "futility...
What does infrared thermography tell us about the evolutionary potential of heat tolerance in endotherms? [0.03%]

Anthropogenic climate change affects wild animal populations through increasing average temperatures and more frequent extreme climatic events. Endotherms have evolved the capacity to regulate their body temperature but little is still know...
Fine-scale spatial variation in fitness, inbreeding, and inbreeding depression in a wild ungulate [0.03%]
有蹄类动物适应度、近交和近交衰退的精细空间变化

Environmental stress can exacerbate inbreeding depression by amplifying differences between inbred and outbred individuals. In wild populations, where the environment is often unpredictable and stress can be highly detrimental, the interpla...

Organism responses to environmental change require coordinated changes across correlated traits, so-called syndromes. For example, animals differ in their "pace-of-life syndrome" (POLS); suites of correlated life-history, behavioral and phy...
The maintenance of genetic polymorphism underlying sexually antagonistic traits [0.03%]
有利于性竞争特征的基因多态性的保持
Ewan Flintham,Vincent Savolainen,Sarah P Otto et al.
Ewan Flintham et al.
Selection often favors different trait values in males and females, leading to genetic conflicts between the sexes when traits have a shared genetic basis. Such sexual antagonism has been proposed to maintain genetic polymorphism. However, ...
Mammalian retinal specializations for high acuity vision evolve in response to both foraging strategies and morphological constraints [0.03%]
灵长目的高视力视网膜适应性进化受取食方式和形态制约的影响

Vision is a complex sensory system that requires coordination among cellular and morphological traits, and it remains unclear how functional relationships among traits interact with ecological selective pressures to shape the evolution of v...
Heritability and age-dependent changes in genetic variation of telomere length in a wild house sparrow population [0.03%]
家屋 Sparrow 种群中端粒长度的遗传变异的遗传率和年龄依赖性变化
Heung Ying Janet Chik,Aaron Sibma,Maria-Elena Mannarelli et al.
Heung Ying Janet Chik et al.
Telomere length (TL) and/or its rate of change are popular biomarkers of senescence, as telomere dynamics are linked with survival and lifespan. However, the evolutionary potential of telomere dynamics has received mixed support in natural ...
Parallel and convergent evolution in genes underlying seasonal migration [0.03%]
调控迁徙性季节节律的基因中的并行和趋同演化现象

Luz E Zamudio-Beltrán et al.
Seasonal migration has fascinated scientists and natural historians for centuries. While the genetic basis of migration has been widely studied across different taxa, there is little consensus regarding which genomic regions play a role in ...
Co-regulation of cooperative and private traits by PsdR in Pseudomonas aeruginosa [0.03%]
铜绿假单胞菌PsdR对合作性和自私性表型的协同调控

Social interactions profoundly shape the dynamics and functionality of microbial populations. However, mechanisms governing the regulation of cooperative or individual traits have remained elusive. Here, we investigated the regulatory mecha...
Positive correlations in susceptibility to a diverse panel of viruses across Drosophilidae host species [0.03%]
果蝇宿主物种对多种病毒易感性的正相关性

Our ability to predict the emergence of novel viruses relies on there being generalisable patterns in the susceptibilities of hosts to novel infections. Studies investigating variation in susceptibility among host species have consistently ...
