Item ИСПОЛЬЗОВАНИЕ ЭКОЛОГО-ФЛОРИСТИЧЕСКОЙ КЛАССИФИКАЦИИ ДЛЯ ВЫЯВЛЕНИЯ ИНДИКАТОРНЫХ СООБЩЕСТВ ВОДОРОСЛЕЙ(CEP USM, 2014) Шкундина, Фаина; Сахабутдинова, ДинараWe used some of the approaches of ecological-floristic classification for the identification of indicator species. The indicator species are used then to assess the environmental conditions in river Belay, Pavlovskoe Reservoir and territory town Sterlitamak Town. The composition of communities reflects the changes in the degree of eutrophication of the water bodies.Item ВОДОРОСЛИ ПОЙМ РЕК ГОРНОГО УРАЛА(CEP USM, 2014) Шарипова, МаринаThis article describes the soil algal formed in the river valley. It was found that taxonomic composition and spectrum ekobiomorf оf algae were more diverse in all areas in the central floodplain. Specific species of algae and cyanobacteria for each studied flood- plain area were revealed. They differed intaxonomicaf filiation and ecological forms.Item ТЕОРЕТИЧЕСКИЕ И ПРИКЛАДНЫЕ АСПЕКТЫ ИССЛЕДОВАНИЯ АЛЪГОФЛОРЫ МОЛДОВЫ(CEP USM, 2014) Шаларь, В. М.; Шалару, В. В.; Унгуреану, Л.Item СОВРЕМЕННОЕ ПОНЯТИЕ, ТРАКТОВКА И ТАКСОНОМИЧЕСКИЙ СТАТУС ГРУППЫ КОККОИДНЫХ ЗЕЛЕНЫХ ВОДОРОСЛЕЙ(CEP USM, 2014) Царенко, П. М.Modern approaches and criteria of differentiation and content of “coccoidal green algae group” are analysed. Its taxonomic differentiation into overgenera level is represented. Issues of taxonomy and complex approach in systematics of this group of algae are discussed.Item РАЗНООБРАЗИЕ ДИАТОМОВЫХ ВОДОРОСЛЕЙ ГОРНЫХ ЭКОСИСТЕМ(CEP USM, 2014) Фазлутдинова, Альфия; Сугачкова, ЕваThe species complexes of diatoms mountain ecosystems in Austria, Georgia, Russia, Turkey and France were studied. The comparative analysis of groups of diatoms on geographical-based position and altitudinal gradient was held. The changes in species composition, structure, complex dominant species and abundance of diatom communities were found. The level of similarity in species composition between the complexes of diatoms mountain ecosystems was determined.Item ПОЧВЕННЫЕ ВОДОРОСЛИ СЕВЕРНЫХ РАЙОНОВ РЕСПУБЛИКИ МОЛДОВА(CEP USM, 2014) Семенюк, Евгений; Шалару, ВикторStudy of soil algae in the Republic of Moldova paid less attention in comparation with aquatic algae. For today in the soils of Moldova is found more than 600 species of these microorganisms. The aim of this work is to identify the structural and taxonomic properties of algal communities in the soils of the northern regions of Republic of Moldova. In the studied soils formed under the main phytocenoses of the northern regions identified 213 species and varieties of soil algae, relating to the 4 divisions, 16 orders, 35 families, 65 genera.Item ЛЬГОФЛОРА ПОЙМЕННЫХ БИОЦЕНОЗОВ ГОСУДАРСТВЕННОГО ПРИРОДНОГО ЗАПОВЕДНИКА «НУРГУШ»(CEP USM, 2014) Пирогова, ОльгаA comparative analysis of soil algae specious diversity in forest and meadow phytocenoces in the nature reserve Nurgush identified 58 species of soil algae. Different plant communities have different species composition (species composition of soil algae varies according to the type of phytocenosis). In forest phytocenoces cyanobacteria and green algae dominate, in meadow phytocenoces green algae dominate.Item РАСПРОСТРАНЕНИЕ EUGLENOPHYTA В МАЛЫХ РЕКАХ СЕВЕРО-ЗАПАДНОГО ПРИЧЕРНОМОРЬЯ(CEP USM, 2014) Миронюк, А. Н.; Ткаченко, Ф. П.At the North-Western Black Sea Region 36 Euglenophyta specieswere identified, relating toClass 1, 2orders, 3 families and 6genera. The greatest number of certain types belongs to Phacus Dujardand Euglena Ehrenb. In seasonal aspect Euglena ehrenbergii Klebs dominated in spring, in summer – Euglena hemichoramata (Ehrenb.) Kütz., Phacus caudatus Hübn., in autumn – Euglena deses Ehrenb. Most often and most massively euglenophytes were meti n the late summer and early autumn. In spring only sporadic isolated instances were found. With respect to organic pollution mesosaprobic group of algae was predominant therefore trophic level in this reservoir ranges from mesotrophic oeutrophic.Item ОСОБЕННОСТИ ДЕЙСТВИЯ ЦИАНОБАКТЕРИЙ НА КОЛОРАДСКОГО ЖУКА В СВЕТЕ ГИСТОПАТОЛОГИЧЕСКОЙ ХАРАКТЕРИСТИКИ(CEP USM, 2014) Гольдин, Е. Б.We have already discussed pathological effects of cyanobacteria on invertebrate organism in our papers. This study involved natural communities of Microcystis aeruginosa and Colorado potato beetle larvae of the second instar: food and insects taken separately and together were treated by 0.5% water suspension of cyanobacterial powder. The dynamics of inhibitory cyanobacterial action and histological alterations were observed in larvae during 7 days. The pathological process took place in midgut (epithelial hypersecretion, vacuolization, proliferation, degradation and desquamation), Malphigian tubes (caryolysis and desquamation in epithelium) and fat body (vacuolization and caryolysis) during the first 24 hours. During the following days these processes progressed (necrosis of midgut epithelium, muscle layer exposed and intestine wall destructed, total degradation and necrobiosis of fat body, dystrophy of Malphigian tubes), alterations in muscle fibres were observed (tissue homogenization, refining of fibres and dystrophy). Treatment of larvae caused the destruction of cuticle, hypoderm, respiratory system and subcuticular fat body. Complex treatment caused intense mortality.Item МИКРОСКОПИЧЕСКИЕ ВОДОРОСЛИ БЕНТОСА ВОДОЕМОВ СЕВЕРО-ЗАПАДНОГО ПРИЧЕРНОМОРЬЯ (УКРАИНА) И ПРИЛЕГАЮЩИХ К НИМ АКВАТОРИЙ ЧЕРНОГО МОРЯ(CEP USM, 2014) Герасимюк, В. П.Researched the species composition of benthic algae, microscopic water bodies (rivers, estuaries, lakes, reservoirs, ponds, puddles) North-Western Black Sea and the adjacent waters of the Black Sea. During 1980-2014 biennium as a result of processing the samples found 2777 and 770 species of algae have been identified of which 25 species have been marked as new for Ukraine and 9 species as new to the Black Sea.
