Аннотация: The change in reproductive mode from parthenogenesis to gametogenesis in Cladocera is controlled by multiple environmental cues. Maternal effects are involved in the control of reproductive switching. In this study, we estimated the readiness of Moina macrocopa females to change reproduction mode under the effect of conspecific chemicals on maternal and offspring generations. The results demonstrated that information about the chemical environment was not transmitted between generations (none of the females produced diapausing eggs in the control medium irrespective of their mothers' environment). Differences in maternal energetic investments were not significant, hence the maternal environment did not affect the fecundity. However, tested animals adapted to the effect of the diapause inducing factor. When offspring of mothers cultured in crowded water were also cultured in crowded water (the constant effect of conspecific chemicals), they switched less readily to gametogenesis than offsprings of mothers cultured in fresh medium.

Аннотация: The volatility and thermal stability of chemicals that are contained in the metabolic products of Moina macrocopa females that stimulate the production of diapausing eggs in these females have been studied in experiments with separately cultivated individuals. It has been shown that the gametogenesis-stimulating chemicals in this species are nonvolatile compounds: the effect of the medium that contains the metabolic products of the organism was not decreased after many hours of blowing with argon. Prolonged heating up to 80 degrees C also did not deactivate the ability of these products to change the reproductive mode. The effect of the medium that contains these products decreased after boiling, but if the possibilities of their oxidation or binding with salts of metals were excluded, they retained the ability to change the reproductive mode of the animals even after boiling.

Примечания : Cited References:17. - The work was performed in part as Federal Tasks to the Department of Animal Ecology of the Institute of Biology of Komi Science Centre of the Ural Branch of the Russian Academy of Sciences (AAAA-A17-117112850235-2) (to EF and OK), to the Institute of Biophysics of the Federal Research Center "Krasnoyarsk Science Center" of the Siberian Branch of the Russian Academy of Sciences (project No. 51.1.1) and the Siberian Federal University (project No. FSRZ-2020-0006) (to OD). The paleolimnological part of this work was supported by grant from Russian Science Foundation (project 20-17-00135). L. Frolova and G. Nigamatzyanova were supported by the subsidy allocated to Kazan Federal University for the state assignment #671-2020-0049 in the sphere of scientific activities and by the Russian Foundation for Basic Research (grant 18-05-00406). The work was partly financially supported by the Russian Foundation for Basic Research (RFBR) grant: 20-04-00145_a (to EF). Monitoring investigations in the Lena River Delta were conducted under the framework of Russian-German, "Lena" expeditions (Alfred Wegener Institute, Potsdam, Germany) with logistic and technical support of Scientific Research Station "Samoylov Island" (the Trofimuk Institute of Petroleum-Gas, Geology and Geophysics SB RAS, Novosibirsk) (to EA).

Аннотация: We present the presence/absence species list (Table 1) of rotifer, cladoceran, and copepod (Calanoida, Harpacticoida, and Cyclopoida) fauna from seven Arctic regions of Russia (the Kola Peninsula, the Pechora River Delta, the Bolshezemelskaya tundra, the Polar Ural, the Putorana Plateau, the Lena River Delta, and the Indigirka River Basin) based on our own and literature data. Our own records were obtained by analyzing samples of zooplankton, meiobenthos, and two cores of bottom sediments (from the Kola Peninsula and the Bolshezemelskaya tundra lakes) that we collected once in July or August in 1992, 1995-2017. To supplement the list, we used relevant literature with periods of research from the 1960s to the 2010s. The list is almost identical to "Dataset 2: Zooplankton and Meiofauna across Arctic Regions of Russia", which was analyzed but not published in [1]. The detailed analysis of this list revealed the specific composition of the aquatic fauna associated with the climatic and geographical factors [1]. The data provide information on the current state of biodiversity and species richness in Arctic fresh waters and can serve as the basis for monitoring these environments and predicting how they are likely to change in the future.
