The first finding of Pseudopotamilla reniformis (Bruguiere, 1789) (Annelida, Sabellidae) in subtidal zone of the Black Sea - Boltachova N.A., Lisitskaya E.V. - Near the coast of the eastern Crimea, a new for the Black Sea species of polychaete worms of Sabellidae family, Pseudopotamilla reniformis (Bruguiere, 1789), was found. It was registered in 2003 in the area of Sevastopol (Kazach’ya Bay) and in 2011 at the Cape Tarhankut on the rocks at a depth of 2–3 m.

Naturalization of alien species Elodea canadensis Michx. in Reservoirs of Bashkortostan - Golovanov Ya.M., Abramova L.M., Muldashev А.А. - The data about distribution of a North American alien species Elodea canadensis in the territory of Republic of Bashkortostan are presented. This species has widely settled in Bashkortostan and may be dangerous to ecosystems of the South Ural. This species has naturalized in reservoirs of the region and occurs in many types of water vegetation, quite often replaces native plants and forms monodominant communities of Elodeetum canadensis association. Elodea canadensis is a part of many other water communities and is founded in 32 associations and 6 unions of classes of water vegetation of Lemnetea and Potametea. The map of a secondary range of Elodea canadensis in the territory of Bashkortostan is made.

The Ponto-Caspian invader Evadne anonyx Sars (Crustacea, Cladocera) in the pelagic zone of the Southeastern Baltic - Demereckiene N.E., Polunina Ju.Ju., Rodionova N.V. - The Ponto-Caspian cladoceran Evadne anonyx (G.O. Sars, 1897) was recorded in the summer zooplankton in the Southeastern Baltic (SEB) in 2010–2011. The quantitative parameters of the species were low. The share of the introduced species in the total abundance and biomass of zooplankton was not significant. The population of E. anonyx was presented predominantly by parthenogenetic females with 1–22 eggs. Among individuals, the males were found, and that allowed the suggestion of the presence of sexual reproduction and resting eggs formation in the populations of E. anonyx in SEB. Morphometric parameters of populations of E. anonyx and fertility of parthenogenetic females in SEB were comparable with those of Caspian forms. It is possible that with the emergence of the new species, E. anonyx, the structural and functional changes may take place in zooplankton community of half-closed Curonian and Vistula lagoons of the Baltic Sea.

Influence of invasive species on the Caspian Sea aboriginal fauna in Azerbaijan coastal waters - Zarbaliyeva T.S., Akhundov M.M., Kasimov A.M., Nadirov S.N., Huseynova G.G. - The results of influence of Mediterranean invaders on aboriginal fauna of the Caspian Sea are shown. The materials about the changes, which are taking place in pelagic and seabed ecosystems, and also in the ichthyofauna of the Middle and Southern Caspian Sea, regarding their quantity and specific composition are presented.

Colonial ascidia Didemnum vexillum Kott, 2002 is an alien species in Peter the Great Bay (the Sea of Japan) - Zvyagintsev A.Yu., Sanamyan K.E., Turanov S.V., Kartavtsev Yu.F. - In November 2013 in Vostok Bay (Peter the Great Bay, the Sea of Japan), in the fouling of experimental installation of the Mytilus trossulus mussel culture, the mass settlements of colonial ascidia not previously observed in Peter the Great Bay were registered. The taxonomic identification of colonial ascidia is rather complicated, and frequently the morphological and genetic methods of the species determination don’t give a clear result. The usage of molecular-phylogenetic methods allowed us to indicate the sequences of nucleotides obtained from 3 colonies of ascidia from the Vostok Bay as inherent to the invasive species Didemnum vexillum Kott, 2002. This species is known as an invader in aquaculture settlements of mussels and oysters in the various regions of the World Ocean in different years.

Anthophilous complex of alien plant Impatiens glandulifera Royle (Magnoliopsida: Balsaminaceae) in the city of Tomsk - Konusova O.L., Mikhailova S.I., Prokopyev A.S., Akinina A.A., Ostroverkhova N.V. - Impatiens glandulifera Royle is an aggressive invasive plant of Himalayan origin, one of the success factors of which is the high attractiveness to pollinators in the secondary range. In anthophilous Impatiens complex in the city of Tomsk 38 species of insects referring to the orders of Hemiptera, Coleoptera, Hymenoptera and Diptera were found. According to the number of species (84% of the species composition), as well as to the number of individuals (99%), representatives of the order of Hymenoptera were dominated. Bumblebees Bombus pascuorum (Scopoli), B. hortorum (L.), B. hypnorum (L.), honeybee Apis mellifera L. were mass species. Some behavior peculiarities of insects on the flowers of Impatiens were studied. The dynamics of abundance of insects – visitors of Impatiens of various ecological groups was studied in seasonal and perennial aspects.

Role of invasions in formation of phylogeography structure of house mice Mus musculus in some territories of Russia and adjacent to Russia territories - Maltsev A.N., Stakheev V.V., Kotenkova E.V. - The role of invasions in formation of phylogeographic structure of commensal species, house mouse Mus musculus, was investigated. The expected paths of this species settling in Russia and adjacent to Russia territories were analyzed. Genetic variability was studied in subspecies and populations of Mus musculus according to the polymorphisms of the control region (D-loop) of mtDNA. The data obtained indicate the presence of three phylogenetic lines living in Russia and neighboring countries: the first line includes house mice from the zone of hybridization in Transcaucasia and M. m. musculus from Moscow; the second one includes house mice from the south of European part of Russia and Western Siberia; the third line consists of M. m. musculus populations from Eastern Europe. Invasions influenced the heterogeneity of phylogeographic structure of M. musculus. None of investigated subspecies (M. m. musculus, M. m. wagneri, M. m. gansuensis) formed a single phylogroup. This is probably due to the hybridization between different parapatric taxa of house mice, both at the specific and intraspecific levels.

Parasitic invasion of alien parasite Nicolla skrjabini (Iwanitzky, 1928) (Trematoda, Opecoelidae) into fish of Saratov reservoir - Mineeva O.V. - Infestation analyzes for trematoda Nicolla skrjabini based on research results made during 2009–2014 in 6 fish species of Saratov Reservoir is given. The natural range of parasite is restricted by the rivers of the Azov – Black Sea and Baltic basins. A high incidence of trematoda in the round goby and bighead goby (Teleostei, Gobiidae), and invasive fish species of the reservoir is registered.

Detection of genotypic changes in the parthenogenetic lizards of Darevskia armeniaca (Mehely) introduced from Armenia to Ukraine - Omelchenko A.V., Girnyk А.Е., Osipov F.А., Petrosyan V.G., Vergun А.А., Ryskov А.P. - The article provides data on allelic and genotypic diversity of Ukrainian and Armenian populations of a parthenogenetic lizard of Darevskia armeniaca. The individual genotypes of studied specimens were established due to combination of alleles of three microsatellite loci. It is supposed that in the introduced Ukrainian population after the invasion two new genotypes appeared. Molecular mechanisms of the emergence of these new genotypes are suggested. Values of observed heterozygosity and genetic F_st-distances for the introduced Ukrainian population, native Armenian population and group of other Armenian populations are provided.

Ecological and morphological characterization of Dreissena bugensis (Bivalvia, Dreissenidae) from Cheboksary reservoir (with the description of deep water ecotype) - Pavlova V.V., Pryanichnikova E.G. - The bivalve mollusk Dreissena bugensis forms two ecotypes in Cheboksary Reservoir – typical (shallow) and deep-water ones. This water body is the only in the European part of the species range where deep-water morph dwells. Two ecotypes differ morphologically (in the ratios of shell height, width and length; in general outlines and byssus strength) and ecologically (they inhabit parts of the reservoir, which differ strongly in environmental conditions). Morphological variability of deep-water morph is lower than that of typical one.

First finding of nesting great white heron Casmerodius albus in Yaroslavskaya oblast - Petrova O.R., Pavlov D.D. - Article presents new data on the northward expansion of great white heron Casmerodius albus nesting range. Nests of great white heron with adults and nestlings were found within grey heron Ardea cinerea colony situated on Radovskii Island on the Rybinsk reservoir in the Yaroslavskaya oblast of Russia in late July of 2015. This finding suggests that great white heron’s nesting range expands towards the north of the European part of Russia.

The eggs of pink salmon Oncorhynchus gorbuscha as additional non-traditional food for juvenile atlantic salmon Salmo salar in the rivers of the Kola Peninsula - Rasputina E.N., Shustov Yu.A., Tyrkin I.A. - Pink salmon was intentionally introduced into the rivers of the White Sea in the last century. It regularly goes to the rivers to spawn, which are always used by Atlantic salmon, and this leads to a certain competition between the species. It is shown in literature that smolts of Atlantic salmon eat juveniles of pink salmon, but there is no information on the consumption of pink salmon eggs by young salmon. In the salmon rivers of the Far East a consumption of eggs of one salmon species by another Far Eastern salmon, for example, chum or coho salmon, is registered. Analysis of young salmon feeding from the rivers Indera, Pulonga (Kola Peninsula) has shown that juvenile Atlantic salmon consumes pink salmon eggs intensively, which increases significantly the index of stomach fullness.

Caspian bighead goby Neogobius gorlap Iljin in Berg, 1949 (Gobiidae, Pisces) – a new alien-fish species in the Moscow River - Skomorokhov M.O. - The first population of Caspian bighead goby – the species, which enlarges its range in European Russia – was recently found in the Moscow River in the limits of the city of Moscow. This population is the first known river population of this species in the Volga basin. The data on habitat-distribution, feeding and growth of these gobies are presented. Caspian bighead gobies inhabit the Moscow inshore artificial stony biotope and, rarely, surrounding bottom lots. The diet of the Caspian bighead goby in the Moscow River mainly consists of fish fries, and large invertebrates are less important Similar pattern of feeding is seen in bighead gobies in the Caspian Sea, but not in the Volga reservoirs, where different invertebrates are prevailing in goby’s food. Growth rate of Caspian bighead gobies in Moscow River is relatively high and is inferior only to that in the Caspian Sea. Several assumptions about the invasion potential of the species are presented.
