AbstractThe list of invasive alien species of European Union concern currently includes 23 plant species. The aim of this study was to assess the potential and importance of introduction pathways for invasive alien plant species in Lithuania, to estimate probability of their establishment and further spread in the country. Analysis of all available information revealed that three species (Asclepias syriaca,Heracleum sosnowskyiandImpatiens glandulifera) currently occur in Lithuania and the latter two are widespread invasive species in the country. The remaining 20 plant species have not been registered in the wild in Lithuania so far. Four of these,Gunnera tinctoria,Lysichiton americanus,Myriophyllum aquaticumandPennisetum setaceum, are occasionally cultivated in gardens or other outdoor areas, and six species, e.g.Cabomba caroliniana,Eichhornia crassipes, Lagarosiphon major, are cultivated in aquaria or other indoor spaces. Naturalization of seven species is unlikely in the country, whereas naturalization of 13 species (Lysichiton americanus,Myriophyllum aquaticum,Pennisetum setaceum, etc.) is plausible. Five of the analysed and still not recorded species are recognized as potentially invasive in Lithuania; the invasion of five species is plausible and that of 10 species is unlikely. The most important pathway of introduction of the analysed species is ornamental gardening. Three species that have not been recorded in Lithuania, but occur in the neighbouring regions of Europe (Elodea nuttallii,Heracleum mantegazzianum,Heracleum persicum) can enter the country by natural means. Importance of permanent studies and surveys on alien plants aiming to ensure early detection and eradication of invasive species is discussed.

Heracleum sosnowskyi Manden, a transformer specie, is in the list of species with status I. It actively intrudes natural communities, changes the face of ecosystems. It is an edifier and dominant. It forms thickets over a large area. Displaces germination of other species. Impatiens glandulifera Royle has status II. This is an adventive specie. It is actively spreading and naturalizing in natural and semi-natural habitats. It has been established that the introduction of these species into the territory of the region and their dispersal over its territory proceeds from the south to the northwest and northeast.

Biological invasions are renowned for their negative ecological and economic implications, however from studying invasions invaluable insights can be gained in the fields of ecology and evolution- potentially contributing towards conservation plans to deal, not only with biological invasion, but with other concerning issues, such as climate change. Impatiens glandulifera, or Himalayan balsam, is widely considered to be a highly problematic invasive, having spread across more than thirty countries during the past century. This paper will examine the findings which have arose from studying I. glandulifera and its impacts on the invaded ecosystem.

Gravel Bars

Abstract Gravel bars are the initial habitats, inseparably connected to the mountain streams. On the one hand, they are an unstable substrate, influenced by the overflows and high waters; however, they are also exposed to strong sunlight and heat. This situation determines specific vegetation which, due to dynamic changes in the habitat, has a pioneer character. What is more, gravel bars are areas where many river migratory species and many random species appear. Among them, there are also synanthropic species. In years 2011-2012, floristic and phytosociological studies were conducted in the Silesian Beskids. The goal of these studies was to recognize the vegetation of the gravel bars of the Vistula and the Brennica rivers - from their springs in the Silesian Beskids to the point where the Brennica River flows into the Vistula River in the Silesian Foothills. The studied section of the two rivers is regulated. Particular attention was paid to the synanthropic species that pose a threat to the native flora. In 9 recognized types of plant communities, 293 vascular plant species were recognized. More than 15% of the flora were alien species (45) and 22 of them were considered to be invasive. The most common invasive species that were spotted included: Impatiens glandulifera, Heracleum mantegazzianum and Reynoutria japonica. Plant communities with the biggest number and share of alien species were Plantago major-Barbarea vulgaris community and Phalaridetum arundinaceae.

This study evaluates the eight forest small-scale specially protected areas (nature reserves: Babí lom, Břenčák, Krnovec, Slunná, Sokolí skála, and Nature monuments: Březina, Květnice, Zlobice) of the total area of 382 ha of the region Tišnov. The evaluation used two methodologies and results of were compared. From the outcomes obtained show that almost all the territories are in good (50%) or moderate (37.5%) status and quality of care is good in most cases (75%). The highest degree of care achieves is in a nature reserve Břenčák, which is generally excellent. The lowest recorded level of care, average, is in a natural monument Slunná. The poor condition or unsatisfactory of care were not found. Of the total area of protected areas and their areas of buffer zones is an average 24% affected by negative events. The most common reason for this effect is a landscape managed by intensive agriculture. Among the most invasive species belongs to Impatiens parviflora DC.; Impatiens glandulifera Royle. These are forming a continuous herb stand. In the trees stand is the most occurrences from invasive species Robinia pseudoacacia L. After comparing the summary results of the two methodologies can be concluded that the findings of both evaluate are very similar. The best current state is in natural reserve Břenčák and the worst state is in natural monument Květnice. Methodologies are different from each other. The methods for evaluate of forest small-scale protected areas were tested as suitable. One method, but should be somewhat modified.

The Impact

Nature reserves are often considered to be assemblages of species in natural or semi-natural communities. However, in many parts of the world they also contain exotic species that interact with the native flora and fauna. An International Working Group has been endeavouring to understand the management of invasive species in natural landscapes. Data for four invasive species within the British Isles are analysed. The case studies investigated include Indian balsam ( Impatiens glandulifera ) , rhododendron ( Rhododendron ponticum ), mink ( Mustela vison ) and coypu ( Myocastor coypus ). The rates of spread have been variable, usually increasing after an establishment phase. The discussions concentrate on assessing the impact of invasive species, on deciding whether control measures are feasible and/or desirable, on deciding whether or not nature reserves are less prone to invasion than other habitats, and on assessing wildlife conservation values when invasive species are present.

ABSTRACT Since Aedes albopictus was discovered in 2011 in the San Gabriel Valley it has become widespread despite the “harsh” environmental conditions and intense efforts to control or eliminate it. Species introduced into a new area may survive, thrive, or disappear depending on whether its new environment is suitable. The San Gabriel Valley Mosquito and Vector Control District expended considerable resources from 2011 to 2015 to eradicate this invasive species or, at a minimum, control and manage its spread. Despite the intense effort, the distribution of Ae. albopictus steadily expanded. Over those 5 years this increase shifted from a geometric to exponential pattern. What enabled Ae. albopictus to survive initially, become established, and then expand their distribution when ecological conditions in southern California were considered hostile for this invasive species? This study explores several biological characteristics including skip oviposition, installment egg hatching, and variable larval development that may have helped Ae. albopictus flourish in its new environment.
