AbstractInvasive plants are non-native, but in most cases naturalised, species that have successfully spread outside of their native range. Aliens invaded all habitats, are competing with native plants, thus, after the direct destruction of habitats, invasions are recognised as the second largest danger for biodiversity. Northern Red Oak is one of the most common invasive tree species dispersed primarily by birds, but new studies have shown that it is also spread continuously in a forest stand. The main aim of our research was to check how strong is the invasion of Northern Red Oak in Silesia Park, where it was introduced together with other alien plant species, and how this invasion interacts with bird diversity. Silesia Park was created 65 years ago on the surface largely ravaged by coal industry. Because many studies indicate birds as vectors of alien plants invasion, we examined the bird fauna in a described area, looking for species that can contribute to spreading oaks. Research showed the diversity of 50 bird species. Surface with a presence of Northern Red Oak was characterised by greater participation of alien plant species than the patch of natural forest, which existed there long before the park creation. The greatest bird diversity was found in the most natural part of Silesia Park, and the lowest in the area of invasion, especially in the case of species classified as “forest birds”. The presence of alien plants increased number of “non-forest” birds, mostly synanthropic species. We also found that Northern Red Oak spreads by spontaneous seed dispersal.

AbstractMany woody plant species that originate from various regions of the world have been introduced in other regions or continents and are used in ornamental gardening, silviculture, erosion control, for fruit sources or other purposes. Woody plants selected for introduction usually originate from regions with similar climate conditions; therefore, after certain time lag they start to spread outside places of cultivation, become naturalized or even invasive. In addition to 77 woody alien plant species reported in Lithuania, ten new species were recorded and analysed in this paper. Information on the native and anthropogenic ranges, first record in Lithuania, size of populations, habitats, reproduction and naturalization of Aralia elata, Berberis thunbergii, Caragana frutex, Celastrus orbiculatus, Cornus alba, Cytisus austriacus, Hydrangea arborescens, Pinus strobus, Rhus typhina and Thuja occidentalis is presented. All these species have been introduced intentionally and are used mainly in ornamental gardening. Three of the reported species, Berberis thunbergii, Hydrangea arborescens and Thuja occidentalis, currently are casual species. Remaining seven species were recognized as naturalized in Lithuania, and five of these, i.e. Aralia elata, Celastrus orbiculatus, Cornus alba, Pinus strobus and Rhus typhina as well as Berberis thunbergii, which currently is treated as a casual, have very high or high probability of getting invasive. Constant survey of potential habitats, detection of new escaped alien plants, particularly of trees and shrubs, is the best way to reveal potentially dangerous species and make timely decisions for their control or eradication, if necessary.

Abstract Background As trade increases, the influx of various alien species and their spread to new regions are prevalent, making them a general problem globally. Anthropogenic activities and climate change have led to alien species becoming distributed beyond their native range. As a result, alien species can be easily found anywhere, with the density of individuals varying across locations. The prevalent distribution of alien species adversely affects invaded ecosystems; thus, strategic management plans must be established to control them effectively. To this end, this study evaluated hotspots and cold-spots in the degree of distribution of invasive alien plant species, and major environmental factors related to hot spots were identified. We analyzed 10,287 distribution points of 126 species of alien plant species collected through a national survey of alien species using the hierarchical model of species communities (HMSC) framework. Results The explanatory and fourfold cross-validation predictive power of the model were 0.91 and 0.75 as area under the curve (AUC) values, respectively. Hotspots of invasive plants were found in the Seoul metropolitan area, Daegu metropolitan city, Chungcheongbuk-do Province, southwest shore, and Jeju Island. Hotspots were generally found where the highest maximum summer temperature, winter precipitation, and road density were observed. In contrast, seasonality in temperature, annual temperature range, precipitation during summer, and distance to rivers and the sea were negatively correlated to hotspots. The model showed that functional traits accounted for 55% of the variance explained by environmental factors. Species with a higher specific leaf area were found where temperature seasonality was low. Taller species were associated with a larger annual temperature range. Heavier seed mass was associated with a maximum summer temperature > 29 °C. Conclusions This study showed that hotspots contained 2.1 times more alien plants on average than cold-spots. Hotspots of invasive plants tended to appear under less stressful climate conditions, such as low fluctuations in temperature and precipitation. In addition, disturbance by anthropogenic factors and water flow positively affected hotspots. These results were consistent with previous reports on the ruderal and competitive strategies of invasive plants, not the stress-tolerant strategy. Our results supported that the functional traits of alien plants are closely related to the ecological strategies of plants by shaping the response of species to various environmental filters. Therefore, to control alien plants effectively, the occurrence of disturbed sites where alien plants can grow in large quantities should be minimized, and the waterfront of rivers must be managed.

Abstract Gudžinskas Z., Petrulaitis L., Arlikevičiūtė L., 2014: Vaccinium macrocarpon - a new alien plant species in Lithuania [Stambiauogė spanguolė (Vaccinium macrocarpon) - nauja svetimžemė rūšis Lietuvoje]. - Bot. Lith., 20(1): 41-45. Extensive colonies of V. macrocarpon Aiton were found in 2013 during the investigations of the flora of Rėkyva wetland complex (Šiauliai district) in a cutover and abandoned Piktmiškis peatbog situated in the environs of Rėkyva village. This species was widely distributed on about 31 ha area and solitary individuals or small patches were recorded in various distance from the dense population in bog woodlands. It is supposed that seeds of this species were dispersed by birds. V. macrocarpon should be treated as a naturalized species in Lithuania. Recommendation to use V. macrocarpon for re-cultivation of cutover peatbogs should be considered with caution in order to avoid its probable invasions in natural, disturbed and degraded bog habitats. Notes on cranberry nomenclature and taxonomy are also provided

Plant invasions pose an unprecedented threat to biodiversity and ecosystems at different spatial scales, especially for a biodiversity-rich developing nation like India. While country-level checklists are considered as the first step for effective management of plant invasions, databases having biological and ecological attributes of these plant species are of paramount importance for facilitating research activities and developing policy interventions concerning alien plant invasion in a country or region. Though checklists with the names and basic details of alien plant species are available for India, a database aggregating attributes relevant to the understanding of the invasion continuum is lacking. We have curated data for 13 variables related to ecology, biogeography, introduction history, socio-economy and environmental niche of 1747 alien vascular plant species from 22 national and global sources to produce the Indian Alien Flora Information (ILORA) version 1.0 database. This paper describes the detailed methodology of curating these data along with the logic behind selecting these variables to be included in the database. The database, first of its kind for the Indian alien flora, will provide easy access to high quality data, offer a ready reference to comprehend the existing scenario of alien plant species in the country and provide opportunities to identify, scrutinize and prioritize the management of these species. The database is dynamic and will be continuously updated with the availability of new data. It has the provision for bidirectional information exchange with the users, which will allow increasing the resolution of the database as well as the expansion of its capacity. All data will be associated with the source information and ILORA will encourage users to refer to the primary sources to give the contributors full credit and acknowledgement. The database is, therefore, envisaged to become a nationwide collaborative platform for a wide spectrum of stakeholders involving the scientific community, citizens, and policymakers. ILORA is freely accessible via an online data repository as well as through a dedicated website (https://ilora2020.wixsite.com/ilora2020).
