daphnia

Adding a lot of algae always makes daphnia reproduce a lot and eventually they eat all the algae.

Apparently, they aren't just able to detect impurities by detecting differences in the way the daphnia move, they are capable of detecting individual compounds because they affect the daphnia differently...

This includes everything from walleye, lake trout, and perch all the way down to daphnia and diatoms.

My research focuses on the ecology and evolution of infectious diseases, particularly in lake Daphnia populations.

Scientists have discovered that the animal with the most genes--about 31,000--is the near-microscopic freshwater crustacean Daphnia pulex, or water flea.

After treatment, the water flows through a glass tank with some daphnia in it (water fleas).

Fish also barely eat daphnia so it is hard to control their population with them.

It would be worth looking into species that exploit cryptobiosis, specifically anhydrobiosis (rotifers, tardigrades, daphnia, and C.

I did end up buying daphnia and moina online since they never colonized the ponds naturally.

Also funny because I've gotten into container ponds, medaka (Japanese ricefish), daphnia/moina and other microfauna over the last 2 months.

I’ve also experimented with raising daphnia in a jar with baker’s yeast as their food.

It is also too hard for daphnia to eat grass.

I also had a couple "pond jars" to maintain the daphnia/moina population.

From a project researching the dormant stages of Daphnia to another investigating pure ecological statistics, projects that appear to have limited public appeal have been successful, due to the tremendous outreach campaigns by the scientists behind them." -- Wheat et al.

Highlight was showing Daphnia, which happened to be pregnant at the time and gave birth live in front of a few visitors ("did we just watch the miracle of birth?") Later I learned that rotting fruit and wet moss from the yard is a great source of microbes, and you can leave standing freshwater with some moss in it to get all sorts of rich ecosystems.

We used it to watch daphnia- at some point the daphnia "gave birth" and a mom who was watching said "we just saw the miracle of life!" I built a Galton Board to demonstrate the Central Limit Theorem, I want to re-do it in all-acrylic and aluminum at some point and add an automated mechanism.

Daphnia should poop instead lay eggs all the time, or alternatively the bacteria should be able to decompose eggs.
