Genomic data are ubiquitous across disciplines, from agriculture to biodiversity, ecology, evolution and human health. However, these datasets often contain noise or errors and are missing information that can affect the accuracy and reliability of subsequent computational analyses and conclusions. A key step in genomic data analysis is filtering - removing sequencing bases, reads, genetic variants and/or individuals from a dataset - to improve data quality for downstream analyses.

Climate-induced expansion of invasive hybridization (breeding between invasive and native species) poses a significant threat to the persistence of many native species worldwide. In the northern U.S.

Environmental change is intensifying the biodiversity crisis and threatening species across the tree of life. Conservation genomics can help inform conservation actions and slow biodiversity loss. However, more training, appropriate use of novel genomic methods and communication with managers are needed.

RNA sequencing (RNA-Seq) is popular for measuring gene expression in non-model organisms, including wild populations. While RNA-Seq can detect gene expression variation among wild-caught individuals and yield important insights into biological function, sampling methods can also affect gene expression estimates. We examined the influence of multiple technical variables on estimated gene expression in a non-model fish, the westslope cutthroat trout (Oncorhynchus clarkii lewisi), using two RNA-Seq library types: 3' RNA-Seq (QuantSeq) and whole mRNA-Seq (NEB).

Article Synopsis
  • Understanding how changes in the environment impact genetic variation and population connectivity is crucial for predicting the adaptability of species to future environmental changes.
  • This study examined two stonefly species in rivers in northwest Montana, using genomic analysis to compare their genetic diversity and differentiation across various sites related to environmental conditions.
  • Key findings include that the mainstem river species (S. coloradensis) exhibited greater genetic diversity compared to the tributary species (S. fidelis), and there were indications of hybridization between species, highlighting the importance of studying adaptive variation in interconnected species for addressing environmental vulnerability.
