Gene flow as a simple cause for an excess of high-frequency-derived alleles [0.03%]
基因流动作为高频率衍生等位基因过剩的简单原因
Nina Marchi,Laurent Excoffier
Nina Marchi
Most human populations exhibit an excess of high-frequency variants, leading to a U-shaped site-frequency spectrum (uSFS). This pattern has been generally interpreted as a signature of ongoing episodes of positive selection, or as evidence ...
Variable resistance to spinetoram in populations of Thrips palmi across a small area unconnected to genetic similarity [0.03%]
Thrips palmi群体在小区域内对spinetoram的可变抵抗性与遗传相似度无关
Pan Shi,Shao-Kun Guo,Yong-Fu Gao et al.
Pan Shi et al.
The melon thrips, Thrips palmi, is an increasingly important pest of vegetables in northern China. Some populations have developed resistance in the field to the insecticide spinetoram. Understanding the origin and dispersal of insecticide-...

Marine protected areas (MPAs) are increasingly implemented worldwide to maintain and restore depleted populations. However, despite our knowledge on the myriad of positive responses to protection, there are few empirical studies on the abil...
Multi-seasonal modelling of plant-nematode interactions reveals efficient plant resistance deployment strategies [0.03%]
植物-线虫互作的多季建模揭示了高效的植物抗性部署策略

Samuel Nilusmas et al.
Root-knot nematodes, Meloidogyne spp., are soil-borne polyphagous pests with major impact on crop yield worldwide. Resistant crops efficiently control avirulent root-knot nematodes, but favour the emergence of virulent forms. Since virulenc...
Whole-exome sequencing reveals a long-term decline in effective population size of red spruce (Picea rubens) [0.03%]
全外显子测序揭示了数百年来美国红杉（Picea rubens）有效种群数量的下降趋势
Thibaut Capblancq,John R Butnor,Sonia Deyoung et al.
Thibaut Capblancq et al.
Understanding the factors influencing the current distribution of genetic diversity across a species range is one of the main questions of evolutionary biology, especially given the increasing threat to biodiversity posed by climate change....
Deciphering genetic mate choice: Not so simple in group-housed conservation breeding programs [0.03%]
解码遗传择偶：在团体饲养的保护繁殖计划中没那么简单
Katherine A Farquharson,Carolyn J Hogg,Katherine Belov et al.
Katherine A Farquharson et al.
Incorporating mate choice into conservation breeding programs can improve reproduction and the retention of natural behaviors. However, different types of genetic-based mate choice can have varied consequences for genetic diversity manageme...
Estimating the contribution of Greenland Halibut (Reinhardtius hippoglossoides) stocks to nurseries by means of genotyping-by-sequencing: Sex and time matter [0.03%]
通过基因分型测序估算格陵兰比目鱼(Reinhardtius hippoglossoides)种群对育苗的贡献：性别和时间起作用

Emilie Carrier et al.
Identification of stocks and quantification of their relative contribution to recruitment are major objectives toward improving the management and conservation of marine exploited species. Next-generation sequencing allows for thousands of ...
Integrating genetic and nongenetic drivers of somatic evolution during carcinogenesis: The biplane model [0.03%]
在致癌过程中整合体细胞进化遗传和非遗传驱动因素：双翼模型
Robert A Gatenby,Stanislav Avdieiev,Kenneth Y Tsai et al.
Robert A Gatenby et al.
The multistep transition from a normal to a malignant cellular phenotype is often termed "somatic evolution" caused by accumulating random mutations. Here, we propose an alternative model in which the initial genetic state of a cancer cell ...
Poly-aneuploid cancer cells promote evolvability, generating lethal cancer [0.03%]
多不整倍体的癌细胞促进物种演化，产生致命癌症
Kenneth J Pienta,Emma U Hammarlund,Robert Axelrod et al.
Kenneth J Pienta et al.
Cancer cells utilize the forces of natural selection to evolve evolvability allowing a constant supply of heritable variation that permits a cancer species to evolutionary track changing hazards and opportunities. Over time, the dynamic tum...

Lauren M F Merlo et al.
Beneficial mutations that arise in an evolving asexual population may compete or interact in ways that alter the overall rate of adaptation through mechanisms such as clonal or functional interference. The application of multiple selective ...
