Universal framework for assessing the environmental impact of marine non-indigenous species in different situations of data availability
Current methods for assessing the environmental impacts of marine non-indigenous species (NIS) are limited by insufficient data, an over-reliance on expert judgement and too coarse a spatial resolution, which ...

Species-specific responses of macrophyte production to the increasing CO2 environment with potential ecosystem implications involved in the Baltic Sea
Macrophytes vary in their ability to utilize carbon in the form of HCO3− and/or CO2 for photosynthesis. Some functional groups that solely use CO2 for photosynthesis could receive competitive advantages from the ...

Ocean acidification may threaten a unique seaweed community and associated industry in the Baltic Sea
Wild harvest of seaweed supports small-scale, high-value industries in a number of regions in the world. Information is lacking on how increasing carbon dioxide (CO2) concentrations in seawater could impact seawe...

Open AccessPredicting lake dissolved organic carbon at a global scale
The pool of dissolved organic carbon (DOC), is one of the main regulators of the ecology and biogeochemistry of inland water ecosystems, and an important loss term in the carbon budgets of land ecosystems. We ...

Open AccessIntegrating experimental and distribution data to predict future species patterns
Predictive species distribution models are mostly based on statistical dependence between environmental and distributional data and therefore may fail to account for physiological limits and biological interac...

Ecological niche differentiation between native and non-native shrimps in the northern Baltic Sea
Invasions of non-native species are modifying global biodiversity but the ecological mechanisms underlying invasion processes are still not well understood. A degree of niche separation of non-native and sympa...

Seasonal variability in the structure and functional diversity of psammic rotifer communities: role of environmental parameters
Data on the variability in structure and functioning of interstitial rotifer assemblages are rare; however, this knowledge is essential for understanding their role in the interstitial food web. In the present...

Open AccessImpacts of changing climate on the non-indigenous invertebrates in the northern Baltic Sea by end of the twenty-first century
Biological invasions coupled with climate change drive changes in marine biodiversity. Warming climate and changes in hydrology may either enable or hinder the spread of non-indigenous species (NIS) and little...

A successful non-native predator, round goby, in the Baltic Sea: generalist feeding strategy, diverse diet and high prey consumption
The round goby Neogobius melanostomus has successfully invaded much of the Baltic Sea. However, very little is known about the feeding habits of the species in this newly invaded environment. Our laboratory exper...

Ecosystem impacts of the widespread non-indigenous species in the Baltic Sea: literature survey evidences major limitations in knowledge
Invasion of non-indigenous species (NIS) is acknowledged as one of the most important external drivers affecting structure and functions of marine ecosystems globally. This paper offers literature-based analys...

Testing effects of shore height level, sediment characteristics and vegetation cover on the seasonality of zoopsammon communities in the two boreal lakes differing in their trophic state
As compared to macroscopic invertebrates zoopsammon communities, i.e. fauna inhabiting interstitial spaces between sand grains are largely understudied and the factors affecting their spatiotemporal variabilit...

Open AccessHow strong is the effect of invasive ecosystem engineers on the distribution patterns of local species, the local and regional biodiversity and ecosystem functions?
One of the most influential forms of biological invasions is that of invasive ecosystem engineers, species that affect other biota via alterations to the abiotic environment. Such species can have wide-reachin...

Open AccessThe effects of exotic seaweeds on native benthic assemblages: variability between trophic levels and influence of background environmental and biological conditions
Biological invasions are among the most severe threats to marine biodiversity. The impacts of introduced seaweeds on native macroalgal assemblages have been thoroughly reviewed. In contrast, no attempt has bee...

Open AccessWhat are the effects of macroalgal blooms on the structure and functioning of marine ecosystems? A systematic review protocol
Anthropogenic activities are believed to have caused an increase in the magnitude, frequency, and extent of macroalgal blooms in marine and estuarine environments. These blooms may contribute to declines in se...

Open AccessSeasonal variability in the grazing potential of the invasive amphipod Gammarus tigrinus and the native amphipod Gammarus salinus (Amphipoda: Crustacea) in the northern Baltic Sea
Mesograzers are known to reduce the biomass of their host plant and modify the structure of the whole macrophyte community in many ecosystems. Thus, the introduction of an efficient mesograzer may destabilize ...
