The small-scale impact of submerged vegetation (locally enhanced water transparency) on abiotic / biotic parameters was studied in a shallow (< 1 m mean water depth) brackish lagoon at the German Baltic Sea coast. Suspended matter, nutrients, chlorophyll, light, and zooplankton composition and biomass were compared between dense and sparse submerge...
Article
This study assessed the genetic relationship between Evadne nordmanni of the Baltic Sea and the North Sea from sequence variation of the mitochondrial cytochrome c oxidase subunit I gene (COI) of 88 specimens from 13 different sites, and from further published data from the Atlantic and Pacific basins. The COI sequences of E. nordmanni from the Nor...

Aim Invasive species are of increasing global concern. Nevertheless, the mechanisms driving further distribution after the initial establishment of non‐native species remain largely unresolved, especially in marine systems. Ocean currents can be a major driver governing range occupancy, but this has not been accounted for in most invasion ecology s...
Article
This study assessed the impact of secondary hard substrate, as being introduced into marine ecosystems by the establishment of wind farm pillars, on the occurrence and distribution of the moon jelly Aurelia aurita in the southwestern Baltic Sea. A two-year data sampling was conducted with removable settlement plates to assess the distribution and p...

Seasonal variations in seawater temperature require extensive metabolic acclimatization in cold-blooded organisms inhabiting the coastal waters of Europe. Given the energetic costs of acclimatization, differences in adaptive capacity to climatic conditions are to be expected among distinct populations of species that are distributed over a wide geo...
Article
The seasonal variability of the intracellular free amino acid (FAA) concentration was studied in 5 Macoma balthica populations and 7 Mytilus spp. populations along their European distribution. Because of the well known physiological role of FAA as organic osmolytes for salinity induced cell volume regulation in marine osmoconformers, FAA variations...

* Corresponding author Received 24 May 2007; accepted in revised form 4 June 2007 Abstract In autumn 2006 the first observations of the West Atlantic comb jelly Mnemiopsis leidyi in Northern Europe were reported from the North Sea, the Skagerrak and the south-western Baltic Sea. Here we report on the further spread of this invasive ctenophore from...
Article
Patterns of nine intracellular free amino acids (FAA), which are utilized as organic osmolytes for salinity-induced cell volume regulation in marine osmoconformers, were compared in five Macoma balthica populations and seven Mytilus spp. populations along their European distribution. Three types of FAA patterns were classified within both taxa: a n...

Host snail demography and trematode parasitism were followed for one host generation in a shallow brackish lagoon of the western Baltic Sea. In addition, a laboratory experiment was simultaneously conducted to quantify the effects of parasitic infection on host fecundity. Hydrobia ventrosa of the cohort of 1996 had a maximum life-span of up to 2 ye...
Article
The component community of larval trematodes infecting the mudsnail Hydrobia ventrosa (Montagu) was examined in coastal lagoons of the southern Baltic Sea among different host subpopulations in relation to the structure of the waterfowl community. The 10 trematode species observed represent the families Notocotylidae (1), Echinostomatidae (1 or 2),...

... Nevertheless, variation in the gut content of individuals in association with seagrass availability constitutes a genuine change in the broader diets of these detritivores. Greater seagrass extent correlated with longer pre-orbital lengths in southern herring (zooplanktivore); this modification may allow fish to better capture invertebrates associated with seagrass (Meyer et al., 2019;Walters and Bell, 1994). Increased pectoral fin heights may assist with manoeuvrability in complex habitats (i.e. ...
... Prevention of secondary spread refers to stopping or slowing down the spread of invasive species that have become established in an area (Vander Zanden and Olden 2008). It is essential in the regions that can potentially become hubs for the spread of invasive species through anthropogenic or natural movement (Jaspers et al. 2018;Seebens et al. 2016;Vander Zanden and Olden 2008). ...
... Numerous studies of seasonal dynamics of cercarial emergence have shown that it stops during the cold season (e.g., Werding, 1969;Robson, Williams, 1970;Lauckner, 1980;Hughes, Answer, 1982;Lemly, Esch, 1984;Schmidt, Fried, 1997;Field, Irwin, 1999;Marcogliese, 2001;Peterson, 2007;Thieltges, Rick, 2006;Prokofiev, 2006). The composition of the groups of parthenitae in the molluscan host also changes in winter (e.g., Køie, 1975;Machkevsky, 1982;Rusanov, Galaktionov, 1984;Ataev, 1991;Taskinen et al., 1994;Abdul-Salam et al., 1997;Sendersky et al., 2002;Kube et al., 2002;Galaktionov et al., 2006;Korniychuk, 2008;Levakin, 2008;Averbuj, Cremonte, 2010;Fermer et al., 2010;Prinz et al., 2010;Nikolaev, 2012;Ataev, Tokmakova, 2015). If there are only two generations of parthenitae (mother and daughter sporocysts) in the group, the development of embryos in daughter sporocysts is suspended, while mature cercariae, that have not emerged before the drop of temperature, may die and resorb during the winter (our unpublished data). ...
... In laboratory and field experiments, plastic and ceramic settling plates are often densely colonised (Miyake et al., 2002). This preference would be especially important in areas of soft sediment, where polyps would not previously have been able to settle (Janßen et al., 2013). Drifting and floating objects provide possible routes for colonization and invasion of new areas, with plastic flotsam a potential habitat for polyps Miyake et al., 2002). ...
... These attributes make M. leidyi not only a potential competitor with pelagic fish species but also an important food web component, especially in higher saline regions of the Baltic Sea [94]. Due to its non-native origin, this species can be regarded as novel graze in the SW Baltic Sea with high abundances since first sightings in 2006 [14], as reviewed in [43]. ...
... While some mechanisms of CVR are relatively well established, it is unclear, whether unifying mechanisms of salinity tolerance exist in marine invertebrates. Osmolyte pool size, as well as pool composition have been suggested to be key factors in determining species salinity acclimation limits, but have not been formally tested across a broader taxonomic range (Pierce, 1971;Berger et al., 1978;Kube et al., 2006). Podbielski et al. (2016) introduced the concept of critical salinity (S crit ), suggesting that osmoconforming animals exposed to hypoosmotic stress reach a critical point that limits their salinity tolerance capacity. ...
... Most of this literature comes from temperate and subtropical latitudes emphasizing the role of temperature as one of the main environmental forcings driving the infection levels of both larval and adult stages of trematodes (e.g. Chubb, 1979 (and references therein); Hughes & Answer, 1982;Galaktionov, 1992;Kube et al., 2002;Jiménez-Garcia & Vidal-Martínez, 2005;Galaktionov et al., 2006;Fermer et al., 2010). The few extant long-term studies on trematode infections have suggested that the infection-level fluctuation has an association with several factors, such as the life span of the hosts (Fernandez & Esch, 1991a, b;Snyder & Esch, 1993;Loy & Haas, 2001;Klockars et al., 2007;Faltynková et al., 2008), temporal heterogeneity of host abundance (Fernandez & Esch, 1991a, b;Snyder & Esch, 1993;Mouritsen et al., 1997;Granovitch et al., 2000;Levakin et al., 2013), eutrophication (Hofmann et al., 2016), variations in rainfall (Pech et al., 2011;Vidal-Martínez et al., 2014;Namsanor et al., 2015) and water temperature patterns (Vidal-Martínez et al., 2014;Zemmer et al., 2017), as well as the effects of hydrometeorological phenomena such as hurricanes . ...
... It is argued that the first consumer would lower resource density and, consequently, the next consumer will not have enough of that same resource to sustain its population, rendering this a costly strategy (Schoener, 1974b). This argument is not applicable to parasites living inside their host because resources are typically more abundant than a parasite can consume, and temporal segregation has been observed in several trematode species (Sousa, 1993;Sapp and Esch, 1994;Kube et al., 2002). Temporal infection patterns have been also reported in studies of gregarines (Locklin and Vodopich, 2010;Forbes et al., 2012;Bunker et al., 2013) but have not been investigated in a community context. ...
... Third, the major osmolytes glycine in green sea urchins and taurine and blue mussels reached maximum concentrations already at intermediate to high salinity. A similar saturation pattern for taurine concentrations was found in bivalves (Kube et al., 2007). At lower salinities the third pattern can either show a linear decrease as described in the first pattern (e.g. ...
