Abstract The paper presents data on a new locality of Oenothera villosa in north-eastern Poland. The species was discovered in the western part of Suwałki in 2013. Two individuals of this rare alien species were found growing in the former sand and gravel pit, where the town dwellers occasionally dump the garden waste. Distribution map of O. villosa in Poland, based on the ATPOL cartogram method, is provided.

Abstract The effects of 5 s–24 h exposure to CuO nanosuspension (nCuO) and CuSO4 on mortality of Nitellopsis obtusa cells within 48 days were investigated. Based on LED50 kinetics, a toxicological endpoint of lethal exposure duration that induces 50% cell mortality, it was shown that mortality response of 10-min treated cells (by 3.2 and 24–79.9 mg Cu/l, respectively CuSO4 and nCuO) did not differ after 12th day rewash in control medium. Larger amount of total Cu (in mg/g cell DM) was measured in charophyte cells exposed to nCuO (79.9 mg Cu/l) than to ionic Cu (3.2 mg Cu/l). The lower nCuO-induced mortality than that of Cu2+ during earlier rewash period could be related to the sorption of nanoparticles on the cell wall, which was confirmed by scanning electron microscope images and energy dispersive X-ray spectrum data. Effect threshold, the shortest exposure duration that induces cell mortality significantly different from the control during a post-exposure period, comprised 30 s in 24 mg Cu/l of nCuO, however, it could not be identified and was less than 5 s in 79.9 mg Cu/l of nCuO.

Abstract Erigeron annuus (L.) Pers. (Asteraceae) is native species to eastern North America, but has been introduced to Europe and many other temperate regions of the world. In order to assess the impact of spreading history and settlement time on the genetic diversity of invasive populations of E. annuus, individual plants were sampled from 16 populations located in Switzerland, Poland, Lithuania and Latvia along the south-northern expansion direction of this species in Europe. One population was collected in native range (New Brunswick, Canada). The analysis of ISSR polymorphism in 253 plants revealed 161 polymorphic bands. The highest genotype variation and genetic diversity parameters were revealed in the populations from Switzerland and Poland, the least – in Latvian populations. All 37 plants from Latvia were clones of the same genotype. The comparison of genetic diversity parameters of populations from different countries showed the decrease of genetic diversity on the south-north direction.

Abstract Desmid algae from three families, 17 genera were registered in the investigated habitats of the Aukštumala Telmological Reserve. A total of 56 desmid algae taxa (50 species and six varieties) were recorded. Species of the Desmidiaceae family dominated. They comprised 73% of all desmid species found. Mesotaniaceae and Closteriaceae comprised 16% and 11%, respectively. The highest diversity was discovered in the samples collected on the margins of the pools (45 species) and in the wet hollows with Sphagnum cover (35 species). Most species were found in the samples collected in August (36 species) or in March and June (25 and 28 species, respectively). The seasonal and spatial distribution of desmid algae species was observed.

Abstract The current study summarised the diversity of cyanobacteria found in various habitats of the second largest raised bog of Lithuania. A total of 56 cyanobacteria species that comprise 19% of all phycoflora diversity in Kamanos raised bog were recorded. Species from the Chroococcales (32 species) order and the Chroococcus (7), Aphanothece (7) genera were the most numerous. Twenty one cyanobacteria species were found in Lithuania for the first time. Most of species recorded in Kamanos raised bog were cosmopolite or distributed in temperate zone. One third of the species were characteristic particularly of the peat bogs. Thirty nine species of cyanobacteria were specific to the particular water body and occurred only in 1–3 of the studied localities. Only five species, i.e. Chroococcus turgidus, Aphanocapsa grevillei, Aphanothece elabens, Cyanosarcina sp. and Hapalosiphon sp. were common. Peculiarities of the habitat were the most important drivers determining species richness and composition of cyanobacteria in a particular locality.

Abstract Woody plant species in recent decades have increasingly often been recorded escaped from cultivation and naturalized. In 2013, a new alien woody species Amorpha fruticosa L. (Fabaceae) was first found in Lithuania. In several Central European countries, A. fruticosa is recognized as invasive species that pose serious threat to natural habitats and ecosystems. To date, A. fruticosa has been registered in three localities in Lithuania: two populations in Ukmergė district and one population in Prienai district. Considering the present state of revealed A. fruticosa populations, it is concluded that this species in Lithuania is already naturalized and potentially invasive. Estimated total area occupied by A. fruticosa in three known localities is about 0.2 ha. In certain areas this species can become abundant and invade significant areas of meadow, forest-edge and other open habitats. Therefore, its immediate control and subsequent eradication can reduce risk of future invasion. Cultivation of A. fruticosa should be forbidden outside the ornamental plantations.

Abstract Two North American goldenrods, Solidago canadensis and S. gigantea, are listed among invasive species posing the greatest threat to species and ecosystems in Europe. Distribution of non-native goldenrods in Lithuania was studied during field trips conducted in 2012–2015 with additional usage of herbarium data. To date, S. canadensis occurs frequently, especially in the eastern part of the country, being the most abundant in Vilnius city, Tauragė district, Vilnius district and Pagėgiai municipalities. S. gigantea occurs frequently in the southern part of the country with the highest abundance in Kazlų Rūda municipality. A total area invaded by S. canadensis amounts to 1702 ha, and by S. gigantea – 411.5 ha. Both species occur mostly in abandoned fields and on roadsides, in communities of ruderal plants of the class Artemisietea vulgaris. The current distribution of S. canadensis and S. gigantea in Lithuania and their competitive potential suggest that these two species are likely to become more common and abundant in the future.

Abstract Drosera intermedia Hayne is one of four species of the genus Drosera in Lithuania. It has the status of an endangered species, however, relatively little is known about its abundance, population size and habitat preference. Seven localities of the species have been indicated in Lithuania till now. Evidence of herbaria is known from four localities. Revision of herbarium specimens revealed the fact that only one sample consisting of six plants was proved to be Drosera intermedia. It was collected in Kamanos raised bog. Distribution of D. intermedia based on recent findings includes two localities in the northern and the eastern parts of Lithuania. Detailed investigations of D. intermedia habitat preference and population size were pursued in the Kamanos State Strict Nature Reserve (Akmenė distr.) in 2013–2014 in five sample plots situated in the Rhynchosporion albae W.Koch 1926 community. The highest density of D. intermedia plants was recorded on bare peat in the mosaic microhabitats of Rhynchospora alba (L.) Vahl and Sphagnum spp. Microhabitats with Sphagnum cuspidatum Ehrh. ex Hoffm. were more favourable than that of Sphagnum magellanicum. There were counted 376 (2013) and 322 (2014) individuals in three sample plots. Next year, 83 plants were appended in two additional plots. Vegetative individuals were more abundant in less favourable areas, while up to 30% of the flowering plants were registered in the depressions of bare peat and Rhynchospora alba mosaic.
