The meiofauna consists of a
number of tiny organisms that cannot be seen with the naked eye. Some of these
are A. Rotifers (Rotifera) Luo Y, Segers H, B. Flatworm (Turbellaria) Eduard Solà, C. Tardigrades/ water bears (Tardigrada) Willow Willow Gabriel, Goldstein Lab,
D. Gastrotrich (Gastrotricha) by Giuseppe Vago, E. Roundworm (Nematoda) by Bob Goldstein.
They are small, but there are many
These small organisms consist of rotifers, crustaceans, water fleas, nematodes and all single-celled organisms. They are a group with many species that are often very numerous and play an important role in the food web of the ecosystem in the reservoirs. Because of their size, it has been difficult to identify species and monitor them effectively.
Flexible operation of hydropower plants gives increased profit to the hydropower industry, but flexibility must be weighed against negative effects on the environment. With more knowledge, the industry can adjust its operating patterns, so that flexible operation has a lower environmental footprint. DNA-based identification of species that are difficult to recognize in other ways makes it possible to map and monitor these species as well. This means that we can get a holistic view of the status of an ecosystem, for example a reservoir, or measure total species diversity before and after changes in the operation of a reservoir.
