Article
Full-text available
Knowledge of the feeding ecology of fishes is fundamental for understanding the processes that function at the individual, population, and community levels and for the conservation of their populations and habitats. Spirlins are widely distributed and often abundant in fast-flowing waters throughout Europe. However, data on their diets are insuffic...
Article
Full-text available
A significant increase in the human population on marine coast and steady growth of maritime water transport causes the construction of port infrastructure and the creation of new lands, which affects the ecosystems of coastal waters. Despite the widespread occurrence of such large-scale engineering projects in coastal areas, their impact on variou...

Full-text available
Teleconnection patterns can be an important tool for investigating the impact of climate change on biological communities. The aim of the study was, using 2003–2020 data on chlorophyll a concentrations (CHL) and plankton primary production (PP) in midsummer, to determine which of the teleconnection patterns have most pronounced effects on phytoplan...
Article

The paucity of data on non-indigenous marine species is a particular challenge for understanding the ecology of invasions and prioritising conservation and research efforts in marine ecosystems. Marenzelleria spp. are amongst the most successful non-native benthic species in the Baltic Sea during recent decades. We used stable isotope analysis (SIA...

Fish inhabiting coastal zone are important link between lower and higher trophic levels in its ecosystems. The aim of this study was to provide more information on the composition of coastal fish and the diet of dominant species in the Neva Estuary, one of the largest estuary of the Baltic Sea. The study showed a diverse coastal fish fauna associat...
Article
Full-text available
Changes in phytoplankton communities due to anthropogenic nutrient load and climate change often lead to eutrophication and harmful algal blooms that can effect biogeochemical cycling. However, little is known about the specific responses of various species to environmental variables. 17-year long data of the midsummer phytoplankton biomass in the...
Article
Full-text available
Biological invasions are a global trend due to globalization of the world. An important goal of invasion biology is to identify environmental characteristics that may make a region receptive to invasions. We tested the hypothesis that environmental variables have stronger effect on the biomass of the alien Cercopagis pengoi in the Neva Estuary than...
Article
Full-text available
Knowledge of carbon and nitrogen isotopic ratios in organic matter and their changes is important when studying nutrient cycles in aquatic ecosystems. Relationships between δ 13 C and δ 15 N values of suspended particulate organic matter (POM), water temperature, salinity, pH, redox potential, chlorophyll a concentration, primary production, and bi...
Article
Full-text available
The article is devoted to the scientific heritage of the outstanding Russian hydrobiologist A.F. Alimov. Showing a deep scientific interest not only in the problems of aquatic ecology, but also in zoology, he laid the foundations of the functional ecology of animals as a common area of interest for ecology and zoology. Further, his views were succe...
Article
Full-text available
Estuaries provide valuable ecosystem services but are threatened by eutrophication caused by increasing nutrient concentrations and climatic factors. We tested the hypothesis that cool and rainy weather in midsummer has a stronger stimulatory effect on indicators of eutrophication in the Neva Estuary than warm weather. The analysis showed that the...
Article
Full-text available
The development of principles and methods for restoring ecological systems that have undergone intense anthropogenic impacts is one of the most important tasks of modern ecology. This work is devoted to studying the regularities of the influence of organic pollution on the structure and functional characteristics of zoobenthic communities and the d...
Article
Full-text available
We investigated the magnitude and intensity of phosphorus turnover and energy flows in the plankton and zoobenthos communities of a shallow, highly eutrophied reservoir. Due to a high degree of reservoir eutrophication, the energy flow through zooplankton significantly exceeded energy flow through zooben-thos. The role of biota in the phosphorus tu...
Article
Organic pollution is a serious environmental problem for the coastal zones of seas. The study tested the hypothesis that allochthonous organic carbon derived from St. Petersburg wastewaters is a significant basal resource of carbon for the benthic food webs. We analyzed stable isotope composition of carbon and nitrogen in suspended organic matter i...
Article
Full-text available
Dinoflagellates account for most of the harmful phytoplankton species but relatively little is known about the specific responses of different species to environmental variables. 21 dinoflagellate species were recorded in the plankton of the Neva Estuary since the mid-19th century. 14-year long data of midsummer dinoflagellate biomass was statistic...
Article
Full-text available
The dynamics of food chains upon changes in water salinity has been analyzed using the example of six poly-and hyperhaline lakes in the Crimea. The results show that ecosystems of saline lakes are sensitive to the impact of external factors. Changes in weather conditions often lead to fluctuations of water salinity, which may cause a changeover in...

188 taxa of benthic animals were recorded in the Neva estuary in 1994-2015. At present, zoobenthic communities in the estuary are dominated by eurybiont indicator species inhabiting “polluted” and “dirty” waters. We used integrated index IP' specially devised for water-bodies and rivers of the north-western Russia to assess the water quality and a...

Coastal shallow waters of the eastern Gulf of Finland keep being the important spawning and nursery area for many species of food and noncommercial fish. On the other hand, coastal fish community is closely related to shallow water biotopes, which are very vulnerable to different threats. In this study based on two years of observations, we report...

Article
Analysis of the isotopic composition of tissues of representatives of zoobenthos and organic matter of seston have shown that the major part of carbon participating in the biological turnover in the ecosystem of the upper part of the Neva estuary is of terrestrial origin. Obviously, it is discharged from the lake drainage area to the Lake Ladoga–Ne...

Neva Estuary is located in the eastern part of the Gulf of Finland. The western boundary of this estuary is not clearly defined geographically, due to the lack of a comprehensive definition of an estuary in general (Elliott and McLusky 2002). In the past, several attempts at subdividing Neva Estuary have been undertaken by researchers. One of the m...

It is hypothesized that the alien amphipods Gmelinoides fasciatus and Pontogammarus robustoides, which have recently invaded the eastern Gulf of Finland, are able to control macroalgae biomass. In order to test this, studies were conducted on the seasonal dynamics of amphipod populations and filamentous algae, Cladophora glomerata, in the Neva Estu...

The zebra mussel Dreissena polymorpha, a ponto-caspian byssate bivalve, forms permanent dense populations along the shoreline in the northern part of the inner Neva Estuary. Its total biomass along a 17 km transect reached 4980 tons (mean 1060 g m(-2)) in 2000 and 6510 tons (mean 1385 g m(-2)) in 2001. Being persistent and abundant, the zebra musse...

Long-term hydrobiological research has shown that the functioning of the ecosystem of the Neva Estuary, one of the largest Baltic estuaries, has changed greatly since the beginning of the 20th century. Ineffective local water management in St. Petersburg during thelast twenty years has stimulated the development of a natural "biological plug" in th...
