Katie Notebook: Results Organized by Population

7/22/17

Now that I officially have all the oysters sampled accounted for, staged, and recorded I split up my results by population as suggested by Laura. I went through and reviewed all my oysters I had previously labeled as HPM or HPF and, based on the literature, (Oates) decided if they were developing hermaphroditic oysters or or actually oysters going towards being male or female (sperm or eggs were degrading). That gave me only three categories to work with and much more visible results. She was right! There do seem to be more differences between populations than between treatments overall. It also seems like overwintering temperature has a bigger impact than OA treatment does, but that is just at first glance. I’m not sure how to pull any significant results from my figures at this point….my statistic skills need some brushing up on.

Check out these results and see if anything should potentially be combined in different ways. The full updated excel document is posted under Histology staging results.

I first made pivot tables to get all the total distributions of sex within each population and treatment:

Then I organized it all in a new spreadsheet so that figures can be easily generated in the future using any combinations of these results:

Then here are some figures I made that show the comparison between overwintering temperature results! Hood Canal oysters show a significant different between the two temperature treatments, South Sound oysters are pretty similar within the population across temperature treatments, and then the Fidalgo Bay oysters are interesting in that they have the exact same results, but there are no females…

I also started play with OA comparison figures. I could do it in two ways: Compare, for example, both the treatments that were overwintered at 10 degrees but had different OA treatments OR I could compare oysters that had the same OA treatment but were overwintered at different temperatures.

For now I am going to work on making a google doc to begin typing up my methods.

Katie’s Notebook: 7/14/17

I finished labeling the oyster tissues for all the other slides/cassettes other than the ones being sampled for RNA that I had already completed. I didn’t go back through and double check all the slides with tissues from the K-treatment oysters because all the oysters in each cassette for the most part are from the same temperature and OA conditions. I did double checked if there were oysters from different treatments on the same slide to make sure to at least differentiate those. All of the labeled cassettes/slides for the the OA treatment are complied here.

I also went back through and had another look at all the slides I originally thought didn’t contain any gonad tissue. I figured as I have looked at hundreds of oysters now I may be able to better find small areas of gonad tissue and I was right! I uploaded and staged all the pictures of the oysters that I preciously had skipped so every oyster Laura used for histology is now documented. I am going to add this new data into my excel document today and start regenerating figures.

Katie’s Notebook: Staging finished! 7/10/17

I finished staging the pictures Grace took of the slides made after overwintering and entered all my data into an excel sheet today! I added all of the sex and maturity data for ever oyster photographed with visible gonad tissue. I then created some pivot tables to get some total distribution information. These are shown in the tables and pie charts in the second picture. Finally I sorted all of the data by sex and maturity stage and totaled how many of each there were in every experimental category. Mostly just played around with different ways to combine the numbers!

Note: Data from the pictures Grace took of the slides from this winter are labeled “post-temp” and data from the pictures I took of the slides from April are labeled as “post-OA”.

Katie’s Notebook: Histology identification and To-Do list

7/7/17
1) Finished staging all of the pictures I took of Laura’s slides and inputed the information into the details section of all of the “low” images on the google drive

2) Identified the tissues on the cassettes that Sam is going to be using based on Laura’s original pictures and her histology key just as I did when I was imaging them. These labeled slides can be lined up with the cassettes to identify which oysters are which!
Histology Slides 1
Histology Slides 2

I took pictures of all the histology slides and cassettes, so I will work on going through and labeling all of Laura’s slides properly to make a usable new key.

3) TO DO LIST FOR THE NEXT WEEK OR SO:
-Stage all of Grace’s post-overwintering histology images and add that information to her google drive.
-Create an excel document with all the oysters from both the post-temperature and post-OA treatments, their, and their maturity stage. This can be used to sort the images and compare treatments/locations.
-Create some example figures for how this information can be sorted in different ways.
-Original cassette orientation/slide matching to create new histology sample key for the post-OA slides.

This To-Do list should allow me to start making observations across treatments!

Katie’s Notebook: Imaging finished!

6/30/17 Finished taking pictures of all of Laura’s OA only slides. I just finished labeling them and they are all uploaded to the google drive. The next step is to figure out how to score them! I’m going to read the papers Grace and Laura have sent me about gonad tissue and rating it today.

Here is a compiled list of all the oysters that I either am not sure whether or not I found gonad tissue (labeled: ?) or oysters that I did not image at all (labeled: no) because I could find nothing that resembled gonad tissue:
HL-10_14: no
HL-6_11: no
HL-6_14: no
NF-6_17: no
HL-6_21: no (only 5 oysters on slide and 6 on key)
NF-10_27: no
SN-6_31: no
NF-6_31: no
K-6_30: no
K-10_35: no
K-10_37: no
K-10_39: no
K-10_44: no
HL-6_13: ?
NF-6_19: ?
NF-6_18: ?
SN-6_18: ?
HL-10_18: ?
SN-10_30: ?
SN-10_27: ?
K-6_17: ?
K-6_18: ?
K-6_20: ?
K-6_24: ?
K-6_29: ?
K-6_40: ?
K-10_22: ?
K-10_27: ?
K-10_28: ?
SN-6_21 ?

Katie’s Notebook: Imaging 6/27

Took pictures of slides 17-21 today. Took a really long time to figure out which oysters were which because 19 was another split slides, and almost all the oysters were rearranged. The ink and Laura’s pictures online continue to be helpful though!

Oly 17 slide: no issues
Oly 18 slide: no issues
Oly 19 slide: Split slide
Oly 20 slide: SN-6_31 and NF-6_31 have no images as I could not find any gonad tissue
Oly 21 slide: no issues

Here is the link to the google drive where I have been uploading all the images!

Katie’s Notebook: Imaging 6/26/17

Took pictures of slides 12-16 today. Ran into a few problems as one of the cassettes (14) isn’t photographed or just wasn’t included in the file I’ve been looking at on Laura’s GitHub. This ALSO happens to be a slide that was split into two slides and contained oysters from two different treatments. So there really is no way to tell which oysters are which on slide 14.

Summary of issues/notes on the slides I worked on today:
Oly 12 slide: There are 6 oyster locations listed on the histology key, but only 5 oysters on the slide/cassette. All the of the supposed 6 oysters were HL-6, so I am not too concerned.
Oly 13 slide: HL-10_18, not sure if I captured gonad tissues
Oly 14 slide: Split slides. 3 smaller oysters on the first slide and two larger oysters on the second. From Laura’s key it looks as if the largest oyster was supposed to be NF-10_26 (third numerically on slide 14), but it was on the second slide. I called the inked oyster and middle oyster on slide one HL-10_20 and HL-10_21, the super large oyster on the second slide NF-10_26, the third oyster on the first slide I called NF-10_25, and the smaller oyster on slide two I called NF-10_27. Unless the original picture can be found though this is just my best guess.
Oly 15 slide: no problems
Oly 16 slide: no problems

I will go back through once I’m done and accumulate a list of the oysters I was unsure about or couldn’t find gonad tissue for. I should be done by the end of this week.

****note: 7/7/17 Found picture of slide 14, fixed image titles on google drive and all tissues have been identified
