Figure 2. Quantitative detection of LM29173.

(A) Prevalence and average load (log₁₀ transformed copy number mg⁻¹ of tissue ± 1SE) of CRESS-DNA virus genotype LM29173 in amphipods from Great Lakes Michigan, Huron, and Superior. Viral load was significantly greater in Lake Michigan than Lakes Huron (Games–Howell post hoc t = 7.30, p = 3.1 × 10⁻⁹) or Superior (Games–Howell post hoc t = 7.30, p = 3.0 × 10⁻⁹); (B) Load of LM29173 (copy number organism⁻¹) in amphipods selected for transcriptome sequencing. Four samples (two with the highest and two with the lowest viral load) were selected from each of three stations: Lake Michigan 27 (Mi27), Lake Michigan 40 (Mi40), and Lake Superior 066 (Su066). Individual transcriptomes are denoted by sample ID (#71, 72, 75, 77, 121, 128, 139, 130, 358, 359, 361, and 362).
