    Opis:
    The world-wide research on ship-aided dispersal of marine organisms and invasions of non-indigenous species focuses primarily on the plankters, which show the greatest potential for invading new areas and establishing viable populations in them, either in the water column (holoplankton) or on the bottom (meroplanktonic larvae of benthic species settling on the sea floor). As meiobenthic animals usually lack a pelagic larval stage in their life cycle, no biological invasion study has, to our knowledge, ever specifically targeted marine transport as a means of meiofaunal dispersal. Here we present a set of data showing that the sediment deposited in a ship’s ballast water tank does support a viable meiobenthic assemblage. We examined 0.015-dm3 aliquots of a 1 dm3 sample from a c. 1.5-cm thick layer of sediment residue in the ballast tank of MS Donnington, brought to the ‘Gryfia’ Repair Shipyard in Szczecin (Poland). The samples were found to contain representatives of calcareous Foraminifera, hydrozoans, nematodes, turbellarians, harpacticoid copepods and their nauplii, and cladocerans, as well as meiobenthic-sized bivalves and gastropods. Nematodes proved to be the most constant and most numerous component of the assemblage. The sediment portions examined revealed the presence of 1–11 individuals representing 11 marine nematode genera. The viability of the meiobenthic assemblage was evidenced by the presence of ovigerous females of both nematodes and harpacticoids. Survival of the meiobenthos in shipborne ballast tank sediment residues may provide at least a partial explanation for the cosmopolitan distribution of meiobenthic taxa and may underlie the successful colonisation of new habitats by invasive meiofaunal species.

    Opis:
    Due to the emergence of new species in ichthyofauna of the Zaporizke reservoir, there was a need to study their biology, ecology and patterns of their distribution. Biological invasions of new species of fish can have diverse effects both within aboriginal populations and within the entire ecosystem. The pumpkinseed Lepomis gibbosus (Linnaeus, 1758) is one of the most common alien species in the Zaporizke reservoir, which has already adapted to the new environment and quickly develops the reservoirs of the region and increases its number. In addition, this species has a wide range of nutrients and can compete for feed resources with other species of fish. The purpose of the work: to study the biological and ecological parameters of the pumpkinseed, the basic laws of its physiology. The paper describes the results of fish morphological studies, estimation of the number and biomass of young fish, determines the morphometric parameters of peripheral blood, determines fertility indexes and features of the course of oogenesis. The paper presents preliminary results of the assessment of the consequences of the invasion of this species in the basin of the Zaporizke Reservoir.

    Opis:
    Riparian zones in two rivers in southern Poland were studied in terms of species composition and soil parameters in patches dominated by three knotweed taxa (Fallopia japonica, F. sachalinensis and the hybrid F. ×bohemica). The main purpose was to detect any differences in species diversity, environmental conditions and in the impact of the three Fallopia spp. on resident species. Fieldwork was conducted in spring and summer in 30 invaded plots (in total 90 subplots). It was demonstrated that vegetation dominated by particular knotweed taxa differed in response to soil pH and ammonium, nitrate, and magnesium content. Fallopia spp. (living plants and necromass) had a stronger negative impact on the cover and species diversity of the resident species in summer in comparison with spring. Vegetation patches differed significantly in species composition in relation to the knotweed taxa present. These differences may be the consequence of the differentiated biotopic requirements of Fallopia taxa and the coexisting plants, or to the different impact of the knotweed taxa on the resident species.

    Opis:
    The fishhook waterflea (Cercopagis pengoi) native to the Ponto-Caspian region, is an excellent example of an invasive species. Within one decade from its first appearance, Cercopagis pengoi has colonized nearly the entire Baltic Sea and most of the Great Lakes of North America. The species spread rapidly owing to its ecological and biological profile. The fishhook waterflea is an euryhaline organism marked by a predominance of parthenogenetic reproduction over sexual reproduction. This taxon quickly colonized inhabited ecosystems to create stable populations. The ecological and economic consequences of the species’ appearance are noticeable, but they have not been fully investigated and require further analysis.
    Wioślarka kaspijska, pochodząca z regionu pontokaspijskiego, jest doskonałym przykładem gatunku inwazyjnego. W ciągu zaledwie dekady, od momentu pojawienia się, skolonizowała prawie cały Bałtyk i większość z Wielkich Jezior Ameryki Północnej. Osiągnęła to dzięki swojej specyfice ekologicznej i biologicznej. Jest to gatunek charakteryzujący się dużą euryhalinowością i dominacją rozmnażania partenogenetycznego nad płciowym. Takson szybko zadomowił się w zasiedlonych ekosystemach i stworzył w nich trwałe populacje. Konsekwencje ekologiczne i ekonomiczne pojawienia się tego gatunku są zauważalne, ale do dziś nie są w pełni poznane i wymagają szerszych analiz.

    Opis:
    The article presents the results of complex laboratory investigations on the biological and biomechanical ways of control of Melanoides tuberculata (Müller 1774) and Tarebia granifera (Lamarck, 1822) molluscs in simulated conditions close to the conditions of the cooling pond of the Zaporizhia Nuclear Power Plant. It was determined that molluscs have naturalized in the Zaporizhia Nuclear Power Plant cooling pond, quickly increased their number and created a threat to hydraulic structures. Taking into account biological features of Thiaridae mollusks and technical and ecological features of Zaporizhia NPP, we carried out a series of experiments using biological control measures (the use of predatory species of hydrobionts) and mechanical means for controlling mollusks. Representatives of different taxons of the Animalia Kingdom were selected as predatory species of hydrobionts, which potentially can consume gastropods: Mollusca, Crustaceans and Fish. It has been found experimentally that the use of marbled crayfish Procambarus virginalis (Lyko, 2017), pumpkinseed Lepomis gibbosus (Linnaeus, 1758) and Botia lohachata Chaudhuri, 1912 has not given positive results in the development of measures to control the number of molluscs. Positive results were obtained in a series of experiments with predatory mollusc assassin snail Clea helena (von dem Busch, 1847), but it was noted that in the presence of more accessible feeds, assassin snail Clea helena (von dem Busch, 1847) consumes smaller quantities of Thiaridae mollusks. The most successful results we obtained in experiments with traps for molluscs. We have developed experimental constructions of traps with lower and upper inlets that act as mollusk accumulator and can be installed in the coastal zone of the reservoir and Zaporizhia NPP cooling system channels for reducing the number of reproductive individuals of Melanoides tuberculata (Müller 1774) and Tarebia granifera (Lamarck, 1822). The most effective were the traps with the lower inlet to which the mollusks could get faster. In order to attract mollusks to traps, we have conducted studies on the use of feed baits for molluscs. Most effectively, molluscs fell into traps that contained lime feed, feedstock sunflower oil and anise oil. The most effective among mollusks was the bait with the addition of anise oil. During the exposure, traps with anise bait traps accumulated 14.1% of molluscs. The conducted researches can serve as the basis for the development of biomelioration measures aimed at reducing the negative impact of accidental introduction of new species of molluscs into technical reservoirs of strategic importance.

    Opis:
    Montia linearis is a vascular plant originating from western North America. The expansion of this species has been observed for several decades. For the first time M. linearis was found in Europe in 1989. Further six populations were documented by 2004 within the continent: three in Poland, two in Denmark and one in Hungary. Apart from discovering a new population of M. linearis, we confirmed two out of the three previously known localities of the species in Poland. All the currently known populations of M. linearis occupied predominantly meadow habitats, especially intensively managed sites. Some individuals were also found in disturbed sites with bare soil. The studied species inhabited soils of various types with broad range of fertility as well as humidity. Montia linearis populations reached densities up to 87 individuals per 0.04 m2. The number of seeds produced by an individual was between 10 and 55 in 90% of the studied specimens, however much more fertile specimens were also observed. As the previously presented hypothesis of M. linearis dispersal with rail transport seemed not to be well supported, the connection between the M. linearis presence and cattle husbandry is considered. It is possible that the species can be transferred with living animals or manure. The species was able to survive for at least 26 years within once inhabited site. Further spread of M. linearis within Europe is highly probable. The aim of the study is to: (i) describe the current state of populations of M. linearis in Poland, (ii) provide information on habitat preferences and biology of the species, (iii) assess the invasiveness potential of M. linearis in Poland.

    Opis:
    Dead individuals of Chinese mussel Sinanodonta woodiana (Lea) were found in 2009 in the complex of fishponds in Spytkowice (S. Poland) in the Vistula River valley. Earlier records of this invasive alien species in Poland come mostly from heated waters. Its occurrence in fishponds indicates that it tolerates also colder waters; many aquatic ecosystems in Poland may be threatened with its invasion. Endangered swan mussel Anodonta cygnea (Linnaues) was found in the same fishponds. The species had not been reported from his area before and it is uncertain whether persistence of its population here is threatened by the invasion of Chinese mussel.

    Opis:
    The paper presents the results of several years investigations (2003-2007) on two invaders: the Himalayans Impatiens glandulifera and Asiatic Reynoutria japonica. The Sudety Mountains and their national parks are under strong pressure of both species, threatening the local vegetation. The four-year investigations have been carried out in field, glasshouse and in laboratory. Invasive species have their peculiar life histories which help them to occupy new areas. Those are above all the specific generative reproduction strategies (Impatiens) or vegetative reproduction strategies (Reynoutria). Both strategies secure the reproductive success and to capture more and more highly situated areas of the mountains. Very significant characteristics connected with the expansion of invaders is the excessively over and above the average production of seeds (Impatiens) and a huge annual increment aboveground biomass (Reynoutria). The investigated invasive species are probably not equipped with influence of allelopatic type as of greater importance is their competitive strength. The invaders can eliminate a part of the early spring flora belonging to the geophyte group and impoverish the regional biological diversity. Both the invasive plants enter also into some moist mountain forest communities.
