This year, two conference schools were held at the Deep Lake Hydrobiological Station (Ruzsky District, Moscow Region), so named because, in addition to lectures by leading experts, they heard reports from all trainees on the topics of their scientific work. Abstracts of these lectures and reports are planned to be published in the RSCI. These schools are organized to improve the skills of hydrobiologists, assist in determining the taxonomic affiliation of their materials and exchange information.
The 5th Conference School on the Systematics and Faunistics of Cladocera (Crustacea: Cladocera), which is the dominant and widespread group of microinvertebrates in continental and marine waters, was held from July 4 to 12, 2022. The school was attended by 7 students (researchers and graduate students) from various scientific and educational institutions of Russia (Astrakhan, Yekaterinburg, Tyumen, Kazan and Moscow). The organizers and teachers were leading experts in the study of cladocerans of the world fauna: corresponding member of RAS A. A. Kotov (IEE RAS), Doctor of Biological Sciences N.M. Korovchinsky (IEE RAS), Doctor of Biological Sciences A.Yu. Sinev (Moscow State University) and Ph.D. O.S. Boikov (IEE RAS).
The second conference school on the biology of freshwater meiobenthos was held from August 29 to September 6, 2022. It was attended by leading experts in the study of this community and its representatives (crustacean groups Cladocera, Ostracoda and Harpacticoida) - E.B. Fefilova (Institute of Biology, Komi Scientific Center RAS), A.N. Neretin (IEE RAS, Moscow) and E.A. Kurashov (Institute of Lake Science RAS, St. Petersburg) and four trainees from Moscow, Astrakhan and Krasnoyarsk.
Lectures were given daily on the morphology, systematics and ecology of the representatives of the studied groups, and practical classes were held to determine them. One day weekly was devoted to excursions to historical sites in the vicinity of Zvenigorod.
