It's complicated: Heterogeneous patterns of genetic structure in five fish species from a fragmented river suggest multiple processes can drive differentiation [0.03%]
错综复杂：来自一个支离破碎河流的五个鱼类物种的遗传结构异质模式表明分化可以由多种过程驱动

Fragmentation of river systems by dams can have substantial genetic impacts on fish populations. However, genetic structure can exist naturally at small scales through processes other than isolation by physical barriers. We sampled individu...
Symmetric response to competition in binary mixtures of cultivars associates with genetic gain in wheat yield [0.03%]
品种对竞争的对称响应与小麦产量遗传增益相关联

The evolution in the definition of crop yield-from the ratio of seed harvested to seed sown to the contemporary measure of mass of seed per unit land area-has favoured less competitive phenotypes. Here we use binary mixtures of cultivars sp...
Overcoming the growth-infectivity trade-off in a bacteriophage slows bacterial resistance evolution [0.03%]
克服细菌噬菌体生长感染权衡以减缓细菌抗性进化

Quan-Guo Zhang
The use of lytic bacteriophages for treating harmful bacteria (phage therapy) is faced with the challenge of bacterial resistance evolution. Phage strains with certain traits, for example, rapid growth and relatively broad infectivity range...
Divergence in heritable life history traits suggests potential for local adaptation and trade-offs associated with a coal ash disposal site [0.03%]

Globally, human activities have resulted in rapid environmental changes that present unique challenges for wildlife. However, investigations of local adaptation in response to simultaneous exposure to multiple anthropogenic selection pressu...
Parasite management in aquaculture exerts selection on salmon louse behaviour [0.03%]
水产养殖中的寄生虫管理对三文鱼鲺的行为产生选择效应

The evolution of pest resistance to management strategies is a major challenge for farmed systems. Mitigating the effects of pest adaptation requires identifying the selective pressures imposed by these strategies. In Atlantic salmon (Salmo...
Response to selection for parasitism of a suboptimal, low-preference host in an aphid parasitoid [0.03%]
寄生低喜好的豆蚜宿主对寄生蜂的自然选择响应

Keith R Hopper et al.
Risks of postintroduction evolution in insects introduced to control invasive pests have been discussed for some time, but little is known about responses to selection or genetic architectures of host adaptation and thus about the likelihoo...
Artificial selection for nonreproductive host killing in a native parasitoid on the invasive pest, Drosophila suzukii [0.03%]
人工选择非繁殖性寄主杀死行为在一个本土 parasitoid 对入侵昆虫 Drosophila suzukii 的作用中的影响

Establishment and spread of invasive species can be facilitated by lack of natural enemies in the invaded area. Host-range evolution of natural enemies augments their ability to reduce the impact of the invader and could enhance their value...
Multiple-batch spawning as a bet-hedging strategy in highly stochastic environments: An exploratory analysis of Atlantic cod [0.03%]
在高度随机环境中作为下注策略的多次批次产卵：对大西洋鳕鱼的探索性分析

Stochastic environments shape life-history traits and can promote selection for risk-spreading strategies, such as bet-hedging. Although the strategy has often been hypothesized to exist for various species, empirical tests providing firm e...
Supporting the adaptive capacity of species through more effective knowledge exchange with conservation practitioners [0.03%]
通过更有效的知识交流增强物种的适应能力以支持保护工作

Carly N Cook et al.
There is an imperative for conservation practitioners to help biodiversity adapt to accelerating environmental change. Evolutionary biologists are well-positioned to inform the development of evidence-based management strategies that suppor...
Planned missing data designs and methods: Options for strengthening inference, increasing research efficiency and improving animal welfare in ecological and evolutionary research [0.03%]
