Item Особенности биологии хитридиевого гриба Rhizophydium mammilatum (braun) fisher–паразита желтозеленой водоросли Tribonema gayanum pash [Articol](CEP USM, 2014) Мамкаева, М.А.Among the lower fungi parasitism is widespread. One of the most commonly affected objects is microscopic algae. Interaction in the system “host-parasite” are poorly understood, both in natural conditions and in culture. Rhizophydium mammilatum– parasite yellow-green alga Tribonema gayanum is one of the most common chytrid fungi in the North-West of the Russian Federation. The ability to detect, and elimination of the parasite gives us an idea of its distribution in nature. Culturing the parasite in the binary culture “host-parasite” gives the prospects of using these objects as a model system for studying aspects of parasitism of microscopic eukaryotes.Item Род Chromulina cienk. в структуре альгофлоры Украины [Articol](CEP USM, 2014) Малахов, Ю.П.Distributional analysis of the genus Chromulina Cienk. in the algal flora of Ukraine is done. Peculiarities of zonal distribution of the genus are discussed. The description and the figure of the newly recorded species are presented. Chromulina verrucosa G.A. is a new species for the Ukrainian flora of algae.Item Фитопланктон и фитоперифитон в разновозрастных карьерных водоемах отработанных меловых месторождений (Беларусь) [Articol](CEP USM, 2014) Макаревич, Тамара А.; Савич, Ирина В.The studies ofphytoplankton andphytoperiphyton were conducted on sixquarry reservoirs, whose age ranges fromless than 1 yearto 60 years. Communities in these waterbodies undergo different stages of ecological succession. It has been shown that the phytoplankton in the early stages of succession (<1 year after flooding ofquarry) is characterized by low values of density and biomass with absolute dominance in biomass of the large colonial algae Dinobryon divergens Jmhof (Chrysophyta). By the number of algae species in the plankton and periphyton of then ewly flooded reservoir (age less than 1 year) dominant were diatoms, while in other reservoirs green algae were dominating. The structure parameters of phytoplankton and phytoperiphyton in the quarry reservoir with the age about 20 years were similar to that in the long-lived (nearly 60 years) reservoirs. This fact gives the evidence of a relatively highspeed of the succession process in plankton and periphyton communities in such reservoirs.Item Обзор диатомовых водорослей бассейна р. Арагви [Articol](CEP USM, 2014) Кухалеишвили, Л.К.In different types of water reservoirs of the river Aragvi basin 263 taxa of 3 classes, 12 orders, 26 families and 45 genera. The order Bacillariophyceae is represented by the highest number of species, the number of which is 216, i.e. 82% of the total number of the diatom species recorded on the study area. The class Fragilarophyceae is represented by 45 taxa, i.e. 17% of the total number of the recorded diatoms. The class Coscinodiscophyceae is represented by only 2 species (1%). Of the species of Bacillariophyceae the following orders are lading by the number of species present: Naviculales (80), Cymbellales (47), Bacillariales (43) and Achnanthales (20). In the class Fragilariophyceae the order Fragilariales is the most diverse on the studied area. The majority of the diatoms recorded by us in the rivers of Aragvi basin are benthic, while phytoplankton is better developed in lakes. In all types of the water bodies species of the following genera are the most frequent: Diatoma, Cymbella, Navicula, Synedra, Gomphonema, Nitzschia,Hannaea, Cocconeis, Fragilaria.Item Dinophyta водохранилища «Деныши» (Житомирская область, Украина )(CEP USM, 2014) Крахмальный, А.Ф.In the present paper seventeen species of Dinophyta belonging to eight genera are reported from “Denyshi” reservoir (Zhytomyr region, Ukraine). Two species – Ceratium furcoides (Levander) Langhans and Peridiniopsis borgei Lemmerm. are new for Ukraine. Detailed descriptions and original drawings along with critical notes are provided.Item Эпифитные цианопрокариоты и водоросли всообществах широколиственных лесов [Articol](CEP USM, 2014) Дубовик, ИринаThe comparative characteristic of taxonomic and ecology structures of epiphytic cyanoprocaryotae-algae cenoses living on tree bark, under the varying degrees of anthropogenic stress in broadleaf forest is given. It was identified 141 species and intraspecific taxa cyanoprokaryota and algae. Forest communities were characterized by relatively high biodiversity cyanoprocaryotae-algae cenoses.Item Влияние рекреационной нагрузки на формирование циано бактериально-водорослевых ценозов в условиях городской среды [Articol](CEP USM, 2014) Суханова, НатальяDue to the increasing urbanization recreational impacts on natural systems is constantly grows. Trampling is primarily reflects on land cover. We studied soil cyanobacterial- algal cenoses with various rate of recreational load in settlements of South Ural forest- steppe zone. There was found 119 species of soil algae and cyanobacteria, including forms and variations. 37 % of them belonged to Cyanoprocariota, 38% – to Chlorophyta, 22% – to Ochrophyta (9% – Xanthophyceae, 12% – Bacillariophyceae, 1% – Eustigmatophyceae), 2% – to Streptophyta , 1% – to Euglenophyta. Biodiversity of edaphotrophs is presented with 5 division, 9 classes, 21 orders, 46 families, 67 genus. We identified a group of frequently occurring species, dominant and subdominant, identified leading families in terms of the number of species. It was found out that the spices diversity and abundance of soil phototrophs increase upon the low recreational influence, at the significant recreational influence – considerable decline.Item Использование эколого-флористической классификации для выявления индикаторных сообществ водорослей [Articol](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 уралa [Articol](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 Mолдовы [Articol](CEP USM, 2014) Шаларь, В. М.; Шалару, В. В.; Унгуреану, Л.
