Supplemental Information

Figure 2: Animal survival, Figure 3: Condition Index over time, Figure 4: pathogen gene copy numbers

Figure 2. Percent survival of experimental red and white abalone held in ambient water (13.6 °C) or at elevated temperature (18.5°C) with and without Candidatus Xenohaliotis californiensis (Ca. Xc) exposure for 343 d; N = 64 for each group at day 0. Each curve represents one of the six treatment groups, with variables: Ca. Xc exposure, seawater temperature, and species. We observe a significant difference between survival curves of red and white abalone held under elevated seawater temperature and Ca. Xc exposure conditions.

Figure 3. Longitudinal plot of mean (+/- standard error) values in condition index (calculated by total abalone weight divided by shell length cubed) over time of experimental groups. Error bars represent standard error of the mean.

Figure 4. Log transformed qPCR-derived Candidatus Xenohaliotis californiensis gene copy numbers from PE tissue at days 161 and 343.
