“…Moreover, the Vistula lagoon offer favorable conditions for the intense development of non-indigenous or alien species like D. mongolianum, D. orghidani, and A. americanus. However, we did not find Eurytemora carolleeae which recently spread in Europe and Poland [43], and Cercopagis pengoi which were known from the Vistula Lagoon [54,71]. Nevertheless, brackish waters are hospitable transitional areas for non-native fauna that may subsequently spread into adjacent freshwater and marine systems [72].…”

“…Temperature and salinity also seem to favor the development of this species, because its optimal temperature range is 5-10 • C and salinities 3-8 PSU [50,51]. We did not find non-native invader Eurytemora carolleeae, which were found in estuaries of the Baltic Sea [52,53] and has recently penetrated the Oder River system in Poland [43].…”

“…The dominant species Eurytemora affinis is widespread in coastal and estuarine waters in the northern hemisphere [43], as well as in the Baltic Sea [44], including the Vistula Lagoon [22]. It often dominates crustacean zooplankton in both freshwater and coastal estuaries [45,46].…”

Shallow brackish water habitats are characterized by highly unstable environmental conditions, which result in low species diversity. We performed our research in the Vistula Lagoon in three seasons in the years 2019–2021. This lagoon is characterized by extremely variable environmental conditions, and our research covered the period of hydro-technical works before opening the canal through the Vistula Spit, which could be an additional stress factor. The aim of our study was to present the particularities of zooplankton communities (Rotifera; Crustacea) in the shallow coastal ecosystem. Our results pointed out very low diversity of zooplankton which could be caused by multi-stress conditions related to increased turbidity and low salinity. Nevertheless, under these conditions, some species achieved an advantage and strongly dominated the zooplankton communities. Domination of Eurytemora affinis in the Vistula Lagoon as well as in other brackish habitats is a well-known phenomenon. Moreover, the Vistula Lagoon offered favorable conditions for the intense development of non-indigenous, or alien, species like Diaphanosoma mongolianum, D. orghidani, and Acanthocyclops americanus. Therefore, brackish waters seem to be favorable transitional areas for non-native fauna that may subsequently spread into adjacent freshwater and marine systems.

“…The presence of the invasive E. carolleeae species in European waters has only been reported in specific locations, namely the Gulf of Finland, the Gulf of Riga, Amsterdam channels , the Oder River (Sługocki et al, 2021), Kiel Bight, Mecklenburg Bight, the Arkona Sea, the Bornholm Sea, the Eastern Gotland Sea (Wasmund et al, 2013) and perhaps in British waters (Gurney, 1931) (Fig. 6, Fig.…”

Abstract. The dispersal of aquatic organisms has especially increased since the 19th century, mainly due to the introduction of metal ships with ballast compartments or with birds. Along with easily visible aquatic organisms, there are invasions of less noticeable aquatic organisms, like copepods, which can mainly be recognized by experts. A special group is made up of cryptic species for which morphological identification is inaccessible or very difficult. This review is devoted to the identification, description and analysis of the dispersal routes of three copepod cryptic species complexes into waterbodies. Using molecular-genetic methods, Eurytemora carolleeae introduction were revealed in 2007. After describing this invader as a new species, its distribution was also studied using morphology. The invasions of Acanthocyclops americanus and Eurytemora caspica were mainly studied using morphological methods since the species have already been described; however, molecular-genetic methods were also used to confirm their distinctions from local forms. The real distribution of the former cosmopolitan species Eucyclops serrulatus was studied using a multidisciplinary approach that combined molecular-genetic, cross-hybridization and morphological methods. Judging by the distribution of local E. serrulatus sensu stricto populations in coastal waterbodies of most continents, this species can apparently serve as a good marker of the species dispersal processes with ships. The three possible scenarios resulting from cryptic species introductions and their interaction with local fauna were competitive displacement (A. americanus), competitive coexistence (E. carrolleeae) and independent development without competition (E. serrulatus). The role of cryptic species invasion in aquatic biodiversity modification is discussed.

Background: Copepods are among the most abundant organisms on the planet and play critical functions in aquatic ecosystems. Among copepods, populations of the Eurytemora affinis species complex are numerically dominant in many coastal habitats and serve as the food source for major fisheries. Intriguingly, certain populations possess the unusual capacity to invade novel salinities on rapid time scales. Despite their ecological importance, high-quality genomic resources have been absent for calanoid copepods, limiting our ability to comprehensively dissect the genomic mechanisms underlying this highly invasive and adaptive capacity. Results: Here, we present the first chromosome-level genome of a calanoid copepod, from the Atlantic clade (Eurytemora carolleeae) of the E. affinis species complex. This genome was assembled using high-coverage PacBio and Hi-C sequences of an inbred line, generated through 30 generations of full-sib mating. This genome consisting of 529.3 Mb (contig N50 = 4.2 Mb, scaffold N50 = 140.6 Mb) was anchored onto four chromosomes. Genome annotation predicted 20,262 protein-coding genes, of which ion transporter gene families were substantially expanded based on comparative analyses of 12 additional arthropod genomes. Also, we found genome-wide signatures of historical gene body methylation of the ion transporter genes and significant clustering of these genes on each chromosome. Conclusions: This genome represents one of the most contiguous copepod genomes to date and among the highest quality of marine invertebrate genomes. As such, this genome provides an invaluable resource that could help yield fundamental insights into the ability of this copepod to adapt to rapid environmental transitions.
