The paper presents the results of the geographic analysis of the family Rosaceae Juss. in the flora of the Chechen Republic based on data of long-term floristic and phytocenological studies. As a ...result of the areographic analysis of 101 species of the studied family, 4 groups of geoelements, which include 15 geographic elements, are identified, and their relationships within the studied flora are revealed. The nature of the flora is established, and the detailed characteristics of geoelements are presented.
Aim. The aim of the research is to study the ecological and biological features and evaluation of the current state of coenopopulations of Tulipa biebershteiniana Roem. et Schult. in the Terskoy ...upland conditions of Republic of Ingushetia (RI), a valuable ornamental species decreasing in number.Methods and materials. T. Biebershteiniana species have been chosen and collected within RI as the material for ecological and biological research. Collection of herbarium material and recording observations, ecological and phenological characteristics of the species have been carried out during two growing seasons (2014-2015) using conventional methods.Result. We have found that on the territory of Ingushetia population of the species Tulipa biebershteiniana Roem. et Schult. can be found only in the area of the Terek ridge on the slopes of the north-western and south-eastern exposures in the vicinity of the rural settlement of Voznesenskaya and Yuzhnoye, in the bushes in a dry clay soils at an altitude of 500-600 meters above sea level sporadically. On the basis of ecological and biological study of features of T.biebershteiniana in terms of its natural habitat we describe ontogenesis and full morphogenesis of its monocarpic shoots. We have also detected the factors limiting its coenopopulations. The growing places of T.biebershteiniana species have been identified, thus we have carried out mapping of its range on the territory of Ingushetia. The soil texture has been studied from natural places of T.biebershteiniana.Conclusion. The research on population status of T. Biebersteiniana on the territory of the Republic of Ingushetia has showed a low density and a limited range of its distribution, and therefore we have made recommendations on taking protective measures of natural spaces of its growth and of making it into the Red Book of the Republic of Ingushetia as a category of III rarity status.
When studying the vegetation of water bodies, it is necessary to pay attention not only to the vegetation of the water body itself, but also to the vegetation of the low part of its shores. Thus, we ...study plants with a different attitude to water: hydrophytes that are real aquatic plants, fully or mostly immersed in water. Hygrophytes, hygrophilous plants that live on excessively moist soil under neutral acidity conditions, are usually found in swamps, along the banks of water bodies, on the swampy soils of meadows and forests. The transition group between hydrophytes and hygrophytes is hygrophytes - amphibians or wetland plants (helophytes). They occupy both aquatic and humid habitats on the shores. Aquatic vegetation is divided into real aquatic and amphibian vegetation.
