Distribution of invasive species of Ambrosia L. genus in the South Urals (Republic of Bashkortostan) - Abramova   L.M. -Data on invasive neophytes of North American origin of Ambrosia L. genus (Ambrosia artemisiifolia L., A. trifida L. and A. psylostachya DC.) progressing in the territory of the Bashkir Republic are presented. These plants are dangerous to ecosystems of the South Urals region. From 3 species of Ambrosia, the greatest number of centers of invasion (more than 60) is noted for A. trifida, number of localities of A. psylostachya are much lesser, A. artemisiifolia has not naturalized in ecosystems of the region and occurs occasionally. Maps of the secondary ranges of invasive species of Ambrosia genus in the territory of Republic of Bashkortostan were made.

Phragmites altissimus (Bеnth.) Nabille (reed very tall) in Ivanovo oblast - Borisova   E.A.,  Shilov   M.P. - Features of Phragmites altissimus distribution in Ivanovo oblast are considered. Vеry tall populations of the reed on the banks of the rivers Uvod, Kineshemka and along the roadsides in the town of Yuzha are described. The range of changeability of the morphological signs and the structural features of Phragmites altissimus shoots are studied. Variability of shoot height and length of inflorescences, to a lesser extent cross the width of the leaf blades, are identified. As a result of measuring the height of young shoots of Phragmites altissimus and Phragmites australis it has been stated, that at the early stages of ontogenesis the invasion species exceed the native ones almost twice as much. Phragmites altissimus in the Ivanovo province has shown a marked tendency to the expansion of populations, and their further distribution. This species passes a complete life cycle successfully, forming inflorescences with the developed garden-stuffs propagating in a vegetative way, and successfully competes with the species of the native.

The invasion of Canadian Goldenrod (Solidago Canadensis L.) into anthropogenic landscapes of Belarus- Gusev   A.P. - The paper considers invasion of Canadian Goldenrod (Solidago canadensis L.) into anthropogenic landscapes of the southeast of Belarus. The maximum occurrence of Solidago canadensis L. is noted for the urbanized landscape. A comparison of repeated geological and botanical surveys at four key sites (2005–2008 and 2015–2016) is made. During this period of time Solidago canadensis L. became a dominant in all those sites and, as a consequence, specific diversity of natural communities decreased.

Asclepias syriaca L. on the territory of the Romensko-Poltavsky geobotanical district (Ukraine)- Dvirna  T.S. - The results of a complex research of potentially invasive species - Asclepias syriaca, on the territory of the Romensko-Poltavsky Geobotanical District are presented. The viability of the seeds of this species and laboratory seed’s germination are studied. In natural conditions its life strategy focuses on vegetative reproduction. A. syriaca forms poor floral biocenoses and grows in communities of the associations Rudbeckio laciniatae-Solidaginetum canadensis Tuxen et Raabe ex Aniol-Kwiatkowska 1974 and Asclepiadetum syriacae Lanikova in Chytry 2009. This species is distributed mainly in biotopes of type I, which are formed as a result of a constant action of anthropogenic factors. According to Invasive Species Assessment Protocol, the level of species invasiveness is high (I-Rank = 95), which indicates the serious threat to native species and natural communities under the influence of the distribution of the A. syriaca.

The first find of Keratella tropica (Apstein, 1907) (Rotifera: Brachionidae) in Western Siberia - Yermolaeva  N.I.,  Kirillov  V.V. -Materials about the first find of a tropical rotifer Keratella tropica (Apstein, 1907) in Western Siberia are presented. Rotifer had been detected in July 2016 in the river Krivoy Uskat (Kemerovo oblast). The Krivoy Uskat is the receiver of career waters from coalmine. The most possible way of the rotifer dispersion is a transfer of meromictic eggs by swimming birds.

Distribution and some biological features of invasive species Harmonia axyridis in the Crimea -Zakharov   I.A.,  Romanov   D.A. - We present data about distribution of an invasive species Asian ladybird Harmonia axyridis in the Crimea, presence in Crimean populations of H. axyridis different morphological types and population ratio of two most numerous species of Coccinellidae – Harmonia axyridis and Adalia bipunctata in connection with their possible competition.

Ways of helminth fauna formation in domestic carnivores in Azerbaijan - Ibragimova   R.Sh. -The specific and characteristic species, intermediate hosts available in a given territory, anthropogenic factors that have an adverse effect and long-lasting preservation of the newly created mixed foci are presented for the first time as composite components that influence the formation of helminth fauna of carnivores. As a result of studies on the territories of Azerbaijan with different biological and ecological features, it was found that helminth fauna of the domestic carnivores is formed by 14 specific helminth species, 24 helminths, characteristic for this area, as well as intermediate hosts of 41 species of helminths and 13 species of helminths of the newly formed mixed foci. Fourteen helminth spesies have epidemiological meaning for man.

The first find of Fistulobalanus kondakovi (Tarasov & Zevina, 1957) (Cirripedia: Thoracica) in Russian waters of the Sea of Japan - Kepel'   A.A. -The barnacles Fistulobalanus kondakovi (Tarasov & Zevina, 1957) was found in the fouling of the floating substrata in the Peter the Great Bay, the Sea of Japan. The possibility of introduction of this species to the Russian waters seems to be unlikely.

Occurrence of Amorpha fruticosa L. in the south of the Russian Far East - Kolyada  N.A.  Kolyada  A.S. -Results of the studies on the occurrence of the North American plant species Amorpha fruticosa L. (Fabaceae Juss.) in the south of the Russian Far East are shown. Today the species is used in landscaping in 26 inhabited localities of Primorye Territory. It is absent in natural phytocoenoses and inhabits anthropogenic landscapes. By the degree of naturalization, the species may be referred to the group of epekophytes. Investigations show potential opportunities for wide spreading by vegetative reproduction. For preventing of its transition to an aggressive agriophytes group the constant control and observation of this potential species are needed.

New data on distribution of two alien species of Helicidae in the European Russia- Mukhanov   A.V.,  Lisitsyn   P.A. -New localities of C. nemoralis in Nizhny Novgorod oblast (the city of Nizhny Novgorod), which are to date easternmost in Europe, and two new localities of A. arbustorum in the city of Dzerzhinsk (Nizhny Novgorod oblast) and the settlement of Borok (Yaroslavl oblast) have been revealed. Morphological variability and modern trends in the spread of C. nemoralis are discussed. It is shown that the diversity of morphes in the places of introduction is significantly lower than in the regions of the main range.
