(1) Re-submitted the Heare et. al paper entitled, “Evidence of Ostrea lurida Carpenter, 1864 population structure in Puget Sound, WA” to Marine Ecology. After contacting the editor, we were able to get an extension on the resubmission deadline as we missed the original deadline of June 26th.
(2) Played around with Rhonda’s geoduck OA data and summarized the data and results:
Over the course of two weeks, the average sizes (microns) of geoduck larvae were recorded. The larvae were separated into six conicals. Three conicals were at pH 8.2, and three were at pH 7.1.
Figure 1. The larvae exposed to the lower pH (7.1) were smaller on average by about 90 microns at the end of the experiment on 5/28/17. (x-axis: date; y-axis: size in microns; key: conical numbers and the pH treatment value→ chart made by Rhonda – personally am unable to add chart features such as axes labels, title, etc.)
Figure 2. On average across all sampling dates, the geoduck exposed to pH 8.2 were larger by about 25 microns than those exposed to the lower pH (pH 8.2 average lengths – 230, 227, 228 microns; pH 7.1 average lengths – 198, 202, 201 microns).
Figure 3. The total mortality observed in each conical and treatment across all sample days. Total number of larvae sampled per treatment and conical = 350 larvae (50 larvae per day and 7 days of sampling).
Figure 4. Across the entire experiment, 350 larvae were sampled from each conical. To determine percent mortality: total number dead divided by 350 total larvae sampled times 100. pH 7.1 and 8.2 weren’t different for conicals 4,6,7,and 9. But conical 8 (pH 8.2) had more than double the mortality of conical 10 (pH 7.1)
