The rapid pace of environmental change has prompted pressing concerns about the persistence of wild populations. For plants, because they move from one place to another only passively between generations, their persistence is especially lik...
Increased adaptive potential in novel environments can be predicted from genetic variance in development time expressed in native environments [0.03%]
在原生环境中表达的发育时间遗传变异可以预测在新环境中的适应潜力提升
Greg M Walter,Keyne Monro,Alastair Wilson et al.
Greg M Walter et al.
While developmental plasticity helps organisms to maintain fitness as environments change, such plasticity has limits. When novel environments exceed these limits and mean fitness declines, the extent of decline is expected to vary among ge...
Developmental speed and chronological time exert opposing effects on the spontaneous mutation rate in Chironomus riparius [0.03%]
发育速度和绝对时间对羽摇蚊自发突变率具有相反的影响
Burak Bulut,Markus Pfenninger
Burak Bulut
The spontaneous mutation rate (μ) is shaped by two distinct forces: the passage of chronological time, inevitably associated with mutation accumulation, and the speed of development, where rapid replication contributes to error rates. Dise...
Pace of life predicts parasite resistance and fecundity tolerance, but not mortality tolerance, among Trinidadian guppies, Poecilia reticulata [0.03%]
生活节奏预测特立尼达小头鳉对抗寄生虫、耐受生育力的能力,但不影响其耐受死亡率的能力
Sadie Evanov,Faith Rovenolt,Natalia Tepox-Vivar et al.
Sadie Evanov et al.
Host defense against parasites can include limiting parasite growth, "resistance," limiting the mortality cost of infection, "mortality tolerance," and limiting the reproductive cost of infection, "fecundity tolerance." Theoretically, these...
Phylograms better fit neutrally evolving traits than chronograms [0.03%]
phylogram比chronogram更适合中性进化的性状
Thibault Latrille,Théo Gaboriau,Nicolas Salamin
Thibault Latrille
At the species level, the evolution of traits is driven by a combination of selective and neutral forces. To disentangle these processes, different scenarios of evolution are modeled and compared. For quantitative traits under selection, th...
Urbanization correlates with genetic and plastic variation of Impatiens capensis flower morphology [0.03%]
城市化与拟齿瓣花形态的遗传和可塑性变异相关性研究
Jérôme Burkiewicz,Julie Carvalho,Sophie Caporgno et al.
Jérôme Burkiewicz et al.
The spectacular diversity of flowers is largely driven by pollinator-mediated selection that favors attractive flowers and effective pollen transfer. Urbanization has the potential to affect floral trait evolution by altering pollinator com...

Sex-chromosome systems are highly variable across animals, but how they transition from one to another is not well understood. Diptera have undergone multiple sex-chromosome turnovers and expansions while maintaining their general chromosom...
Not just mutations: inbreeding depression persists without genetic variation [0.03%]
不只限于突变:没有遗传变异的情况下近交衰退仍将持续存在
Nicolás Bonel,Christoph Grunau,Patrice David
Nicolás Bonel
Inbreeding depression (ID)-the reduction in fitness with increasing parental relatedness-is classically attributed to the expression of recessive deleterious mutations in homozygous individuals. Yet, the assumption that ID can only arise fr...
Longevity is heritable and negatively genetically correlated between the sexes in yellow-bellied marmots [0.03%]
长寿是可以遗传的,并且黄腰鼠兔的雌雄长寿具有负性基因相关性
Michela N Dumas,Bennett Krasnay,Carol-Ann Chabot et al.
Michela N Dumas et al.
Longevity, a major fitness component, is heritable in multiple species, including both captive and wild populations, and often varies widely between the sexes. The sex-specific genetic architecture of longevity, however, has rarely been est...
Origins of violence: evolutionary decoupling between mild and lethal conspecific aggression in primates [0.03%]
论暴力的起源:论灵长类动物中轻微与致死之同类攻击在进化史上的区别发展过程

Bonaventura Majolo
Theories on the evolutionary origins of human aggression have often implicitly assumed that conspecific aggression is a single behavioral trait. However, different types of aggression can be described, based upon their intensity, frequency,...
