This study compares transcriptomic responses of non-lethal and lethal tissues in Chinook salmon exposed to different salinity levels, finding greater gene expression differences in lethal tissues and positive correlations across time points.

This study shows that early-life thermal fluctuations in zebrafish increase cellular stress responses and thermotolerance in later stages, but this effect diminishes over time.

The paper uses mucus transcriptional profiling to identify thermal stress in bull trout, finding a 94.1% accurate biomarker panel comparable to other tissues.

The paper develops a multispecies qPCR chip to assess acute thermal stress effects on three Acipenser sturgeon species, finding species- and population-specific mRNA expression changes.

This study examines how high temperature and low dissolved oxygen affect lake trout's thermal tolerance and cellular stress response through transcriptomic analysis of gill, liver, and mucus tissues.

The paper examines how behavioural responses to acute warming in Brook Trout precede shifts in cellular and physiological thermal stress responses, identifying a potential link between behavioural avoidance and transcriptome changes.

This study identifies 18°C as a critical sublethal thermal threshold for juvenile bull trout, beyond which acclimation capacity declines and stress responses increase.

The paper develops multi-species qPCR assays for a STP-Chip to assess salmonid resilience to environmental stressors, finding tissue and genus-specific amplification success across 8 species.

This study examines how rising CO2 and temperature affect lake sturgeon development, finding altered transcriptional patterns and reduced metabolic rates under combined stressors.

This study examines transcriptomic responses of sea lamprey gills to TFM, niclosamide, and their mixture, identifying gene expression changes related to cell cycle, DNA damage, and immune function.

The paper shows that higher temperatures reduce transcriptional plasticity in lake sturgeon populations, with southern populations showing greater plasticity than northern ones.

This study investigates the transcriptomic responses of bluegill to niclosamide and a TFM:niclosamide mixture, identifying detoxification mechanisms and cellular processes involved in tolerance.

The paper examines how gene expression variation and detoxification gene diversity contribute to differential pesticide tolerance between invasive sea lamprey and a native bluegill species.

The paper examines genetic diversity and structure of an invasive fish population in eastern North America, finding low diversity, no population subdivision, and a single introduction origin.

The paper uses RNA sequencing to analyze genetic variation in walleye from Lake Winnipeg, finding low population divergence and latitudinal transcript variation, suggesting a connected metapopulation for conservation management.
