With the discovery of a major effect region (GREB1L, ROCK1) for adult migration timing in genomes of both Chinook Salmon and Steelhead, several subsequent studies have investigated the effect size and distribution of early and late migratio...
A genomic region associated with iteroparous spawning phenology is linked with age-at-maturity in female steelhead trout [0.03%]

Age-at-maturity and iteroparity are two life history variations of steelhead trout (Oncorhynchus mykiss) that are believed to increase population resilience and stability. While repeat-spawning individuals are thought to have historically m...
Harnessing the power of regional baselines for broad-scale genetic stock identification: A multistage, integrated, and cost-effective approach [0.03%]

In mixed-stock fishery analyses, genetic stock identification (GSI) estimates the contribution of each population to a mixture and is typically conducted at a regional scale using genetic baselines specific to the stocks expected in that re...

Age at sexual maturity is a key life history trait that can be used to predict population growth rates and develop life history models. In many wild animal species, the age at sexual maturity is not accurately quantified. This results in a ...
The genetic legacy of the first successful reintroduction of a mammal to Britain: Founder events and attempted genetic rescue in Scotland's beaver population [0.03%]
英国首次成功重新引入哺乳动物的遗传遗产：苏格兰海狸种群中的创始事件和尝试性基因救援
Helen R Taylor,Jean-Marc Costanzi,Kara L Dicks et al.

Conservation translocations often inherently involve a risk of genetic diversity loss, and thus loss of adaptive potential, but this risk is rarely quantified or monitored through time. The reintroduction of beavers to Scotland, via the Sco...

Understanding the adaptive potential of populations and species is pivotal for minimizing the loss of biodiversity in this era of rapid climate change. Adaptive potential has been estimated in various ways, including based on levels of stan...
Ecological disturbance reduces genomic diversity across an Alpine whitefish adaptive radiation [0.03%]
生态干扰降低了高山白鱼适应性辐射的基因组多样性

Genomic diversity is associated with the adaptive potential of a population and thereby impacts the extinction risk of a species during environmental change. However, empirical data on genomic diversity of populations before environmental p...
Efficient population representation with more genetic markers increases performance of a steelhead (Oncorhynchus mykiss) genetic stock identification baseline [0.03%]
使用更多遗传标记有效表示种群可以提高虹钢鱼(Oncorhynchus mykiss)遗传库存识别基准的性能

Genetic stock identification (GSI) is an important fisheries management tool to identify the origin of fish harvested in mixed stock fisheries. Periodic updates of genetic baselines can improve performance via the addition of unsampled or u...
Structural genomic variation in the inbred Scandinavian wolf population contributes to the realized genetic load but is positively affected by immigration [0.03%]
瑞典狼种群的结构性基因组变异对其实际遗传负载有贡献，但移民对此有正面影响

Linnéa Smeds
When populations decrease in size and may become isolated, genomic erosion by loss of diversity from genetic drift and accumulation of deleterious mutations is likely an inevitable consequence. In such cases, immigration (genetic rescue) is...
Size-dependence of food intake and mortality interact with temperature and seasonality to drive diversity in fish life histories [0.03%]
食物摄入量和死亡率的体型依赖性通过温度和季节性变化相互作用来推动鱼类生活史多样性
