摘要溪红点鲑具有高度的生活史变异、显著的遗传变异和精细的种群结构。在许多情况下，相邻的种群可能彼此高度分化，其程度与其他类群的物种水平差异相当。虽然遗传样本已经收集了数百个群体和数万人，很少有人知道是否在中性标记的分化反映溪鳟鱼种群之间的表型差异。我们比较了四个地理位置接近的地点（均在24公里内）的种群之间的形态分化和中性分子标记，以研究遗传多样性如何与形态协变。我们发现显着差异和/或流内的所有三个形态轴检查，并确定了许多个人的源流形态（52.3%的分类效率）的基础上。虽然分子和morp...
AbstractBrook Trout Salvelinus fontinalis exhibit exceptional levels of life history variation, remarkable genetic variability, and fine-scale population structure. In many cases, neighboring populations may be highly differentiated from one another to an extent that is comparable with species-level distinctions in other taxa. Although genetic samples have been collected from hundreds of populations and tens of thousands of individuals, little is known about whether differentiation at neutral markers reflects phenotypic differences among Brook Trout populations. We compared differentiation in morphology and neutral molecular markers among populations from four geographically proximate locations (all within 24 km) to examine how genetic diversity covaries with morphology. We found significant differences among and/or within streams for all three morphological axes examined and identified the source stream of many individuals based on morphology (52.3% classification efficiency). Although molecular and morp...
