Dispersal and emerging ecological impacts of Ponto-Caspian species in the Laurentian Great Lakes.
Impacts of these benthic invaders vary with site: in some shallow areas, habitat changes and the Dreissena → round goby → piscivore food chain have improved conditions for certain native game fishes and waterfowl; in offshore waters, DreissENA is competing for settling algae with the native amphipod Diporeia spp.
The Baltic—a sea of invaders 1
Further study is warranted to quantify large-scale ecosystem changes in the Baltic associated with establishment and population growth of nonindigenous species and to prevent futureInvasive species have resulted in major changes in nearshore ecosystems, especially in coastal lagoons and inlets.
A Census of Marine Biodiversity Knowledge, Resources, and Future Challenges
A global review of gaps in marine biodiversity knowledge and resources is overdue because society and many scientists believe the authors have discovered most species, or that doing so is out of fashion except when new technologies are employed.
Trophic status of the south-eastern Baltic Sea: A comparison of coastal and open areas
Primary production, nutrient concentrations, phytoplankton biomass (incl. chlorophyll a) and water transparency (Secchi depth), are important indicators of eutrophication. Earlier basin-wide primary
Highlights of zooplankton dynamics in Estonian waters (Baltic Sea)
Cercopagis pengoi, a newcomer from the Ponto-Caspian region, has occupied an important niche in the pelagic food web in shallower areas of the Gulf of Riga and supports a significant component in the diet of planktivorous fish species during summer.
International arrivals: widespread bioinvasions in European Seas
A country-based approach was applied to assess patterns of NIS richness in ES, and the principal introduction routes and vectors, the most widespread NIS and their spatial and temporal spread patterns were identified.
Status of Biodiversity in the Baltic Sea
Although in comparison with fully marine areas the Baltic Sea supports fewer species, several facets of the system's diversity remain underexplored to this day, such as micro-organisms, foraminiferans, meiobenthos and parasites, and climate change and its interactions with multiple anthropogenic forcings are likely to have major impacts on the Baltic biodiversity.
Population dynamics and ecological impact of the non-indigenous Cercopagis pengoi in the Gulf of Riga (Baltic Sea)
It is pointed out that the invasion of Cercopagis has caused changes in zooplankton dynamics and dietary overlap with fish larvae and planktivorous fish may occur in the Gulf of Riga.
