Reading up on the Daphnia that live in my tiny pond. "Neck-teeth"

#daphnia

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.

Researchers reveal how genetically identical #WaterFleas develop into different sexes https://phys.org/news/2024-05-reveal-genetically-identical-fleas-sexes.html paper: https://www.nature.com/articles/s41598-024-59774-1

"#Daphnia are tiny #crustaceans, or water fleas, that are extremely adaptable to their environment. This is due to their remarkable phenotypic plasticity, i.e., their ability to change their form or behavior despite their genetic makeup remaining unchanged. Even male and female Daphnia are genetically identical."

Trying something new this year, and simulating expected results for a Daphnia experiment this summer.

Working through (1) expected daily passage of #Daphnia into each stage in a life table and (2) predicted growth rates.

I am tired of being caught in unplanned late nights when Daphnia births are booming - ha I at least want to know in advance when to cancel dinner, with what probability!

(shown here, expectations for time from hatching to generation F3 for D. pulex and D. magna)

Experimenting with Tetrapak printing Daphnia, weird little planktonic crustaceans a few millimetres in length known as water fleas.

This one is Daphnia longispina, a Eurasian fresh water flea found in bodies of water of various sizes, as small as rock pools up to large lakes. They mainly eat algae.

Tetrapak printing is something you can do with Tetrapak containers - in this case an empty box of juice!

Decades-old crustaceans coaxed from lake mud give up genetic secrets revealing #evolution in action
Human actions are changing the environment at an unprecedented rate. Plant and animal populations must try to keep up with these human-accelerated changes, often by trying to rapidly evolve tolerance to changing conditions. researchers demonstrated rapid evolution in action by sequencing the #genomes of a population of #Daphnia pulicaria,

The Linkage-Disequilibrium and Recombinational Landscape in Daphnia pulex https://buff.ly/3tJzD5C #science #evolution #biology #daphnia #recombination

We (PhD of Sarah Rousseaux, supervised by Steven Declerck and Luc de Meester) had great data measuring population variation in #Daphnia life history traits, and also surveys of the same life history traits from numerous other Cladocerans in the region.

I would like to share more widely our paper from late 2021, we measured (1) how much #Daphnia local evolution contributes to community trait structure and (2) what drives ⬆️⬇️ values of this contribution in a natural metacommunity
