West Coast Green Crab Experiment Part 70
Adding demographic information to respirometry analysis
Just popping in here to say I updated my respirometry analysis to properly account for the impact of various demographic variables! Modifications done in this script.
Notes:
- Statistical output found here
- No demographic variables were significant
- I……forgot to do a multiple test correction when I was originally looking at the impact of experimental variables on oxygen consumption. Turns out when you do the necessary corrections, only temperature is a significant predictor of oxygen consumption! Not day, and not the interaction between temperature and day. This is different than the 2022 experiment where temperature and day were both significant. I think the main difference here is that the 25ºC condition wasn’t eliciting as stressful of a response as the 30ºC condition did. There’s a slight increase in oxygen consumption between days 7 and 14, and a slight difference in variation in consumption at day 14, but other than that things are pretty consistent.
- No impact of genotype variables on oxygen consumption. This makes me sad because you’d think with HIF-1a mutations we’d see something going on! But perhaps there’s more to be studied at the molecular level.
Guess it’s time to open up the new molecular datasets!
Going forward
- Revise respirometry analysis
- Preliminary metabolomics analysis
- Preliminary RNA-Seq analysis
- Examine HOBO data from 2023 experiment
- Demographic data analysis for 2023 paper
- Start methods and results of 2023 paper
