104 moss species were found in the vicinities of Portovaya Bay of the Gulf of Finland. The annotated list of species includes information on habitats, substrate and sporophyte production for every species. The peculiarities of moss flora are considered. One of the recorded species — Aulacomnium androgynum — is rare and protected in Russia.

Vyborgsky Sanctuary occupies the coastal zone of the Gulf of Finland and Vyborg Bay, the northern part of the Kiperort Peninsula, Lisy Island and about 40 adjacent small islands. The annotated list of 171 moss species and brief analysis of the moss flora are provided. Aulacomnium androgynum (Hedw.) Schwagr. is included in The Red Data Book of Russia (2008), Ulota drummondii (Hook. et Grev.) Brid. is new for the Leningrad Region and 9 species are protected in the Leningrad Region.

This study introduces a prototype model for evaluating measures to abate agricultural nutrients in the Baltic Sea from a Finnish national perspective. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient loads from land and other sources, benefits from nutrient abatement (in the form of recreation and other ecosystem services) and the costs of agricultural abatement activities. The aim of the study is to present the overall structure of the model and to demonstrate its potential using preliminary parameters. The model is made flexible for further improvements in all of its ecological and economic components. The results of a sensitivity analysis suggest that investments in reducing the nutrient load from arable land in Finland would become profitable only if the neighboring countries in the northern Baltic committed themselves to similar reductions. Environmental investments for improving water quality yield the highest returns for the Bothnian Bay and the Gulf of Finland, with smaller returns for the Bothnian Sea. Somewhat surprisingly, in the Bothnian Bay the abatement activities become profitable from the national viewpoint, because the riverine loads from Finland represent a high proportion of the total nutrient loads. In the Gulf of Finland, this proportion is low, but the size of the coastal population benefiting from improved water quality is high.;

Three new morphotypes of chrysophycean stomatocysts with long spines are described following International Statospore Working Group (ISWG) guidelines and illustrated by SEM micrographs. Differences of our new morphotypes from known stomatocysts are discussed. Their biological affinity is currently unknown.

The results of the calculation of the inflow of pollutants into the Gulf of Finland with the outflow from Saint Petersburg watercourses are considered. Data of regular hydrochemical observations by State Unitary Enterprise “Vodokanal of Saint Petersburg” for 2018 were used for the calculation. The contribution of the megalopolis of Saint Petersburg to change of the pollutants inflow is estimated.
