This tube rack contains our fist pellet diet vs. algae diet experiment and our 30 ppt vs 60 ppt rearing experiment. Each experiment has 20 isofemale lines (1 isofemale line per tube).
We started a new diet experiment with the same food options (algae and pellet diets), but with a new set of copepods. Each petri dish holds one isofemale copepod line.
Big 10-ft waves hit our main tide pool, bringing lower salinity water and a new environment to our copepods.
Continuing to engineer our own tank, we're making progress in many areas, specifically hypoxic water to test heat ramps in.
We're investigating the effects of diet on the copepods' pigment in their body and egg mass color by raising 10 copepods on an algae diet, and 10 copepods on an algae pellet diet that can be bought from the store. On the left, the algae-fed copepod displays a brighter orange color, compared to the right image of a pellet-fed, green bodied copepod.
Brian is working on programming a tank for our copepods - learning code and applying it to calculate various water quality measurements like pH, oxygen levels, etc.
Using individuals from our main tide pool, we're testing their thermal tolerance in a PCR machine (pictured to the right). On the left, two individuals still alive after a heat ramp a few days ago.
Tigriopus will live in a small tide pools within the intertidal shore - pictured on the right is our main tide pool from which we take samples and measurements. On the left is the beautiful view we get every time we go out :)
