Genomics of Brook trout in Germany
North American brook trout were introduced to Germany in the 19th Century and have since become invasive in many streams. Although important to future management strategy, current population structure remains unknown. By comparing environmental variables for three streams in the state of Baden-Württemberg and SNPs across the genomes of those streams' naturalised brook trout populations, we investigated the genetic distinction between populations and the relationship to mirrors environmental differences.
