Coate, Ho & Schaack examine the patterns of spontaneous mutations in regions of low and high transcription in two species of Daphnia, finding that mutations are more frequently observed in regions of high transcription in both species.

This looks like an interesting new paper: https://doi.org/10.1002/ece3.72624

It suggests that #daphnia in urban lakes have evolved in response to #LightPollution.

It would be great to see if this effect can be replicated in Europe and North America, and tested along a gradient.

I found a temporary little LED light to use for my daphnia tank, and now that I can see them again, holy COW they are prolific little crustaceans. What started with a small sample is already a large cloud of little white pinpricks darting through the water. I can see why breeding them as live food for fish is popular — this will be both cheaper and much healthier overall for the fish in my aquarium.

Since I have sand in the tank (as I eventually plan on having a few fancy shrimp and snails in there as janitorial staff), chlorella algae grows extensively on the bottom; so rather than keeping the tank lit 24/7 as many daphnia breeders do, I’ll be doing a normal day/night cycle so they settle down and eat the algae towards the bottom at night.

I actually got some good(-ish) aquarium pics tonight!
