The red tide of Chattonella marina (Subrahmanyan) Hara & Chihara occurred in Rushan coast, Shandong Peninsula, China, in August 2008. Based on the four cruises of routine monitoring and four cruises of monitoring of the red tide in Rushan, the process of the red tide and possible mechanism were analyzed. During the bloom, the maximum area of the red tide was about 100 km2; the maximum average cell abundance of C. marina reached 1.46×106 cells/L; surface water temper-ature ranged between 26.1 °C and 27.2 °C, and salinity between 26.6 ‰ and 30.3 ‰. The material released from the decayed green tide species Ulva prolifera could provide a chance for the bloom of C. marina, combined the optimum sea temperature, light and nutrient condition. It was the first time to link a red tide event with the consequence of the green tide in Yellow Sea, which could give an attention on our future monitoring and management.

Abstract The Ulva prolifera green tides in the Yellow Sea, China, which have been occurring since 2007, are a serious environmental problem attracting worldwide attention. Despite extensive research, the outbreak mechanisms have not been fully understood. Comprehensive analysis of anthropogenic and natural biotic and abiotic factors reveals that human activities, regional physicochemical conditions and algal physiological characteristics as well as ocean warming and biological interactions (with microorganism or other macroalgae) are closely related to the occurrence of green tides. Dynamics of these factors and their interactions could explain why green tides suddenly occurred in 2007 and decreased abruptly in 2017. Moreover, the consequence of green tides is serious. The decay of macroalgal biomass could result in hypoxia and acidification, possibly induce red tide and even have a long-lasting impact on coastal carbon cycles and the ecosystem. Accordingly, corresponding countermeasures have been proposed in our study for future reference in ecosystem management strategies and sustainable development policy.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.

Nodosilinea epilithica Perkerson et Casamatta is reported for the first time for Russia. The sample was isolated from a typical chestnut soil in the zone of dry steppes (Volgograd Region) and its identity was confirmed by morphological and molecular analyses. The specific feature of the studied strain is its ability to form nodules at normal (60–75 μmol photons ∙ m-2 ∙ sec-1) light. The number of nodules is supposed to be related to the age of a cyanobacterial culture.

Until recently only two species of Gyalideopsis (G. piceicola and G. alnicola) were known from very few localities in Russia. Gyalideopsis helvetica is reported for the first time for Russia from the southern part of Baikal area (KhamarDaban Range, Baikalsky Zapovednik). Description of the collected specimen and its comparison with the literature data are provided; morphology, ecology and distribution of G. helvetica are discussed. The hyphophores of G. helvetica are recorded and described for the first time. An identification key to Gyalideopsis species known in Russia is provided.

The parasitic louse fly Ornithomya comosa (Austen, 1930) (Diptera, Hippoboscidae), known from the Oriental Region (India, Thailand, Nepal and Peninsular Malaysia) and Asian part of the Palaearctic Region (Kazakhstan, Kyrgyzstan, West Siberia of Russia and Japan), is found for the first time in Europe and in the western part of Russia (Curonian Spit). Flies were collected from the swallow species Hirundo rustica (Linnaeus, 1758) and Delichon urbica (Linnaeus, 1758) (Hirundinidae). Two possible narratives for the occurrence of this fly in Europe are discussed.
