Abstract Due to climate change the pathogenic bacterium Vibrio vulnificus proliferates along brackish coastlines, posing risks public health, tourism, and aquaculture. Here we investigated previously suggested regulation measures reduce prevalence of V. , locally through seagrass regionally reduction eutrophication consequential formation algal blooms. Field samples collected in summer 2021 covered salinity gradients Baltic Sea, one largest areas worldwide. Physico-, biological-...
Abstract Background Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments water. Z. typically found marine systems, but it can also proliferate under brackish conditions. Changes salinity generally have a strong impact on biota, especially at salty divide between 6 9. To better understand of interaction sediment microbiota, we investigated effects meadows across range 6–15 Baltic Sea during summer...
Seasonal variations in seawater temperature require extensive metabolic acclimatization cold-blooded organisms inhabiting the coastal waters of Europe. Given energetic costs acclimatization, differences adaptive capacity to climatic conditions are be expected among distinct populations species that distributed over a wide geographic range. We studied seasonal adjustments two very common bivalve taxa at European scale. To this end we sampled 16 Mytilus spp. and 10 Macoma balthica from 39°...
Abstract Aim Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after initial establishment non‐native remain largely unresolved, especially in marine systems. Ocean currents can be a major driver governing range occupancy, but this has not been accounted for most invasion ecology studies so far. We investigate how well areas interconnected to later occupancy regions test potential role ocean secondary spread dynamics order infer...
In autumn 2006 the first observations of West Atlantic comb jelly Mnemiopsis leidyi in Northern Europe were reported from North Sea, Skagerrak and south-western Baltic Sea. Here we report on further spread this invasive ctenophore towards central Sea up to south eastern Gotland Basin during autumn/winter spring 2007. The abundances generally low (max. 4 ind. m -3 ). While M. was located entire water column Kiel Bight, it found exceptionally below halocline deep stratified basins. Data a...
Background The Vibrio genus comprises several bacterial species present in the Baltic Sea region (BSR), which are known to cause human infections. Aim To provide a comprehensive retrospective analysis of -induced infections BSR from 1994 2021, focusing on ‘big four’ – V. alginolyticus , cholerae non-O1/O139, parahaemolyticus and vulnificus eight European countries (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland Sweden) bordering Sea. Methods Our includes data infections,...
Vibrio vulnificus is a natural inhabitant of coastal brackish waters worldwide and an opportunistic pathogen that can cause severe infections septicemia through seafood consumption or wound exposure. Due to global warming, its abundance increasing at high latitudes. While the species harbors diverse virulence factors, precise disease mechanisms remain unclear. Comparative genomics between clinical environmental isolates help identify key genes, but limited availability genomes from has...
The component community of larval trematodes infecting the mudsnail Hydrobia ventrosa (Montagu) was examined in coastal lagoons southern Baltic Sea among different host subpopulations relation to structure waterfowl community. 10 trematode species observed represent families Notocotylidae (1), Echinostomatidae (1 or 2), Heterophyidae (2), Monorchidae Microphallidae (3 4), Psilostomatidae and Hemiuridae (1). Eight these infect as adults. communities similar between sampling sites. Seven taxa...
Temporal variations in the prevalence of larval trematodes short-lived prosobranch mudsnail Hydrobia ventrosa (Montagu) were investigated relation to host life history and season for 4 successive years temperate windflats southern Baltic Sea. The component community trematode larvae H. comprises at least 10 species; families (and species) represented include Notocotylidae (1), Echinostomatidae (1 or 2), Heterophyidae (2), Monorchidae Microphallidae (3 4), Psilostomatidae Hemiuridae (1)....
Host snail demography and trematode parasitism were followed for one host generation in a shallow brackish lagoon of the western Baltic Sea. In addition, laboratory experiment was simultaneously conducted to quantify effects parasitic infection on fecundity. Hydrobia ventrosa cohort 1996 had maximum life-span up 2 years reproduced between May November their second calendar year 1997. Snails died after reproduction. The first infections appeared 1997 when snails started mature. Total...
This study assessed the genetic relationship between Evadne nordmanni of Baltic Sea and North from sequence variation mitochondrial cytochrome c oxidase subunit I gene (COI) 88 specimens 13 different sites, further published data Atlantic Pacific basins. The COI sequences E. Seas were represented by a coherent cluster 28 haplotypes dominated central haplotype that accounted for over half individuals these seas, all samples except one Arkona Basin (Baltic Sea). Overall, populations appear...
