Immigration of Acer negundo L., Asteraceae into the floodplain forests of the North-west of the Orenburg region - Abramova  L. M.,  Agishev  V.S.,  Khaziakhmetov  R.M. -Acer negundo L., the invasive wood species of North American origin, is naturalized in the floodplain forests of Orenburg region. Now A. negundo has created an extensive secondary range in the territory of Orenburg region and occupies the space more than 20 thousand hectares. On the right and left sides of the river Tok in Krasnogvardeysky and Grachevsky districts in the northwest of Orenburg region 4 test areas of 20 × 2000 m were laid, 40 test plots of 20 × 50 m were laid inside of each, and 9 wood species were considered; the data of records were recalculated for 1 hectare. In wood communities of the floodplain of the Tok, an absolute dominance of A. negundo which in number exceeds all other inundated tree species (281.13 and 383.25 pieces/hectare) is noted. The share of invasive species in the floodplain forests of this area averages 66.39%. The carried-out accounting of natural renewing of wood vegetation showed the considerable superiority in strength of undergrowth of A. negundo (130833.50 and 178831.50 pieces/hectare). Naturalization of A. negundo in floodplains of Orenburg region influences negatively the body height, development and renewal of local forest-forming species that leads to irreversible consequences of degeneration of the floodplain forests.

Altitudinal distribution of alien plant species on the Western CaucasusAltitudinal distribution of alien plant species on the Western Caucasus- Akatova  T.V.,  Akatov V.V. -Altitudinal distribution of 100 alien plant species in the mountainous part of the Western Caucasus is considered. Of these, 59% are herbaceous plants, 41% are woody; most come from North America and East Asia; 57% are cultivated plants. The maximum number of alien plant species is concentrated in the lower zones of mountains with a more favorable climate, high population density and significant human impact. With an increase in altitude above sea level, their number decreases. This is typical of most mountain systems in the temperate zone. Above 1000 m a. s. l. only 17 alien species are present. These are mainly accidentally introduced annual herbaceous plants, natives of North America. Most of them are widespread in the Western Caucasus, in many regions of Russia and in Europe. Above the timberline in the subalpine belt (2000 m a. s. l.), one species is noted – Matricaria suaveolens. The differences in the altitudinal distribution of alien species on the southern (Black Sea) and northern (Kuban) macro-slopes of the Western Caucasus are shown. It has been suggested that the main way of penetration of alien species in the upper mountain belts of this region is to import diaspora with materials used in the construction and reconstruction of roads, the building of tourist infrastructure and other objects.

Character of occurrence and abundance of common ragweed (Ambrosia artemisiifolia L.) with evaluation of its distribution potential in European Russia - Afonin  A.N.,  Fedorova  Y.A.,  Li  Yu.S. -A field study conducted in the European territory of Russia provided the data on abundance, occurrence of common ragweed (Ambrosia artemisiifolia L.) and, as a result, allowed to assume the possible boundaries of its naturalization. The result was a better understanding of ecological limits of common ragweed distribution in correlation with limiting factors of the environment. In European Russia the accumulated heat during the seed ripening period is the main limiting factor of ragweed’s invasion to the north. The eastern and southeastern boundaries of the common ragweed range in European Russia are limited by insufficient moisture supply. In order to conduct environmental niche modeling of ragweed distribution, considerably accurate ecological maps were used, which were compiled using the data from the MODIS/Terra satellite sensors. As a result, an accurate map of common ragweed distribution for European Russia was produced, showing the possibilities of its naturalization throughout the territory.

The Elodea canadensis Michx. records in Novosibirsk region (Russia)- Kipriyanova  L.M.,  Efremov  A.N.,  Kotovshchikov  A.V., Yanygina  L.V.-Elodea canadensis was found in July 2016 in the Ust-Tarksky district of the Novosibirsk Region, in July 2016 and in July – August 2018 - in three bays of the Novosibirsk Reservoir: Ordynsky, Sharapsky and Karakansky. In the Sharapsky Bay, the elodea formed thickets about 34000 м² in area and of high productivity (with the phytomass range of 417–1352 g/m² of absolutely dry wt.). These records appear to be the first confirmed data for the Novosibirsk Region, since all the previous mentioning are either the result of an erroneous definition, or do not have documentary evidence, or were cited from earlier publications to the later ones. The reasons are discussed for the fact that on the territory of the Novosibirsk Region with a significant area of 177.8 thousand km² Elodea canadensis has just begun its expansion, while in many regions of Siberia it manifests itself as an active invasive species. It was concluded that the leading factors limiting the distribution of Elodea canadensis in Novosibirsk Region include the composition and degree of mineralization of natural waters, as well as high representation of the local species Hydrilla verticillata in the water bodies, which are potentially suitable for the growth of elodea.

Current state and distribution of alien weedy Cardamine occulta Hornem. (Brassicaceae) in European Russia- Leostrin  A.V.,  Mayorov  S.R.-Cardamine occulta Hornem. (Brassicaceae), an East Asian weedy bittercress, have introduced globally in recent years. First record of this neophyte species in European Russia was made in 2003. According to current data C. occulta was found in nine regions: Leningrad Oblast, Moscow Oblast, Saratov Oblast, Vologda Oblast, Yaroslavl Oblast, the Republic of Karelia, the Udmurt Republic, the city of Moscow and the city of Saint Petersburg. All known populations of C. occulta occupied predominantly man-made habitats. Currently, the species is considered to be a casual or naturalized alien plant. Uncontrollable transfer of the weed along with ornamental plants might lead to its successful spread across the European Russia. Distribution history of the species, as well as a potential for further spread in European Russia are briefly discussed. The main diagnostic morphological features are presented in comparison with those for allied C. hirsuta L. and C. flexuosa With.

Impact of the invasive species Cercopagis pengoi (Ostroumov, 1891) on the structural and functional organization of zooplankton in the Vistula lagoon of the Baltic Sea - Naumenko  E.N.,  Telesh  I.V.-The article presents the results of long-term monitoring studies of the abundance dynamics of the invasive species Cercopagis pengoi (Ostroumov, 1891) in the Vistula (Kaliningradskiy) Lagoon of the Baltic Sea and its impact on the structural and functional organization of zooplankton community. The data on the effect of the invader on zooplankton taxonomic structure and productivity were obtained. It was discovered that, on the long run, the general complexity of plankton community increased, while the impact of C. pengoi on zooplankton measured by the Impact-index decreased. At the same time, abundance and production of the dominant species of Rotifera, Cladocera and Copepoda decreased. For the prognostic purposes, the equation was calculated to correlate the predation pressure of C. pengoi on zooplankton community with the average abundance of this invader.

The emerald ash borer focus in Tver city, in the North-western border of the invasive range - Peregudova  E.Y. -The emerald ash borer is a serious pest of ash (Fraxinus spp.) in North America and European Russia. It was introduced to those territories from East Asia in the 1990s. Currently the pest has established in 12 regions of European Russia. The north-western border of its range is in the city of Tver. This poses a potential threat to ash trees of St. Petersburg and Western Europe. In 2016 and 2018 green ash trees were surveyed in several districts of Tver. There are only local foci of emerald ash borer in the city, mass drying of ash trees is not observed. In the same trees Agrilus convexicollis (Coleoptera, Buprestidae) and emerald ash borer parasitoid Spathius polonicus (Hymenoptera: Braconidae) was found. Both species are recorded for Tver Oblast for the first time. Besides, parasitoid Coeloides sp. was found inside the bark beetle galleries.

Palaemon longirostris (Decapoda: Caridea) is an alien species in the Russian sector of the Black Sea - Statkevich  S.V. - In the coastal zone of the Crimea, a new for the Russian sector of the Black Sea species of shrimp Palaemonidae family, Palaemon longirostris H. Milne Edwards, 1837, was found. It was registered in the Sevastopol bay (the city of Sevastopol) in July 2018. 

The find of Heracleum ponticum (Lipsky) Schischk. in the Leningrad Oblast -Tkachenko  K.G.,  Zhiglova  O.V.- In 2018, in the Priozersk district of the Leningrad Oblast, a place of growth of a new species, Heracleum ponticum (Lipsky) Schischk., was discovered for the flora of the region. The H. ponticum does not contain photo-dynamically active furocoumarins, but interspecific hybrids of this species with the Heracleum sosnowskyi Manden. may contain substances in their juice composition that are dangerous for human skin. Approximate growing area of the H. ponticum is almost 0.7 ha.

Materials to the Black List of flora of the Central Caucasus (Within Kabardino-Balkarian Republic): Part two  -Chadaeva  V.A.,  Shhagapsoev  S.H.,  Tsepkova  N.L.,  Shhagapsoeva  K.A. - The Black List of the Kabardino-Balkarian Republic flora is completed. Information about other 47 species with pronounced invasive potential has been added to the information on 22 invasive plant species published previously. The article presents description of naturalization history, distribution, ecological and biological and phytocenotic features of species in the region. The Black List plants are divided into four groups with assignment of invasive status according to the classification recommended for keeping Black books.

New information about the records of the alien rotifer Kellicottia bostoniensis (Rousselet, 1908) (Rotifera: Monogononta: Brachionidae) in the Nizhny Novgorod oblast-Shurganova  G.V.,  Zhikharev  V.S.,  Gavrilko  D.E.,  Zolotareva  T.V.,  Ruchkin  D.S.- As a result of hydrobiological studies in 2017 and 2018, new information was obtained on the distribution of the alien species Kellicottia bostoniensis (Rousselet, 1908), discovered in 5 different-type rivers for the first time. In the rivers Gnilichka, V'yunica, Chernaya and Kerzhenets, and also Cheboksary Reservoir the rotifer was re-registered. Lower reach of the Vetluga River is at the same time the most eastern and northern find of this species in the territory of the Nizhny Novgorod Oblast. The paper has analyzed the finds of K. bostoniensis in the floodplain lakes of the Kerzhenets River, which are new habitats of this species in the Nizhny Novgorod Oblast. It has been found that rotifers are common in water bodies with different depths and different morphometric and physicochemical parameters. For the first time K. bostoniensis is registered in reservoirs of European part of Russia with a water color of more than 1000 degrees (Lake Novaya Staritsa – 1245.0 deg.), as well as in waters with a low content of dissolved oxygen (0.2 mg/l – Lake Novaya Starica)

Alien species of the family of Brassicaceae Burnett in communities of saline ecotopes of the South-East of Europe -Yuritsyna  N.A.,  Vasjukov  V.M.- The article presents the data on introduction of alien species of the family of Brassicaceae Burnett into the plant communities of saline ecotopes of the South-East of Europe – extent of their participation in formation of cenoses, distribution, ecological characteristics of the species habitats. In the pointed ecotopes, only 3 representatives of this family – Descurainia sophia (L.) Webb ex Prantl, Lepidium ruderale L. and Sisymbrium loeselii L. are registered. Descurainia sophia is the speсies which is met most often and widely in such communities, but two others are noted very restrictedly – both quantitatively and geographically.
