Species Composition and Floristic Analysis of Plants in Yuanyang Wetland Park, Henan Province

The aim of the paper is the floristic analysis at the Krasnoyarsk forest-steppe pine cenoses. This problemrequires detailed research under the constant anthropogenic pressure. A flora inventory was carried out, vascular plantsspecies composition was determined. As a result, a summary of the flora was compiled, which includes 126 species from107 genera, 46 families, 6 classes, 5 divisions. Floristic analysis was carried out by the method of specific flora, taking intoaccount herbarium materials. The taxonomic, chorological, zonal, ecological, biomorphological flora structure featureswere determined based on the analysis of floristic data. The protected taxes have been identified. The peculiarities ofvegetation cover species composition are marked on the basis of the comprehensive flora analysis. The authors madethe conclusion that mesophytes of the light-coniferous and forest-steppe belt-zone groups with the Eurasian and EuroSiberian ranges predominate in the pine cenoses flora at the Krasnoyarsk forest-steppe. The most part of species havethe life forms hemicryptophytes and cryptophytes. Species to be protected have been discovered: Cypripedium calceolus,C. guttatum, C. macranthon, Neottianthe cucullata.

The City

The purpose of the study was to identify the species composition of weed plants and its features on ruderal habitats on the territory of Vyborg city (Leningrad region, Vyborg district). Materials collected during the route survey of ruderal habitats on the territory of the settlement. Systemati-zation of monitoring data, floristic analysis of species composition, calculation of species occur-rence and assessment of its persistence were carried out. The specific structure is presented by 58 species, 48 genus, 18 families. Groups of 21 dominant and 15 concomitant in occurrence species are allocated. Brought species of weeds were revealed. The interrelation of species compositions of weed plants of segetal habitats of the region and ruderal habitats in the territory of the settlement is shown (17 species, identified on ruderal habitats of the city, are dominant in the fields of the region).

High Degree

In terms of its plant richness, the Tien Shan occupies a special place among the mountain systems of Central Asia. According to many scientists, the Tien Shan is conditionally divided into three parts - western, central (inner) and northern. In the geographical nomenclature, onomastics and toponomics of modern sovereign Kazakhstan, the original name Tanirtau is used instead of the term Tien-Shan. Western Tanirtau is the most floristically rich mountain ecosystem in Kazakhstan, where the bioclimatic zones from deserts to glaciers are represented in all their diversity. The generic coefficient of the flora of Western Tanirtau is the highest in Kazakhstan and reaches 4.12, which indicates a high degree of autonomy and originality of the flora of Western Tanirtau.

Special report on dendroglaciological currently missing. The essence of the floristic analysis given in this paper is to identify the leading families of the dendroflora of Western Tanirtau. The species composition of tree and shrub plants collected and recorded in all natural, anthropogenic and urbanized ecosystems of Western Tanirtau were the objects of study. Research objectives: inventory of the species composition of the dendroflora of Western Tanirtau; compilation of the floral spectrum of the dendroflora; identification of the leading families of the region.

Floristic Analysis

The main objective of this paper is to report the diatom taxa identified from the Nisava River and its tributaries, the Jerma and Temska rivers. The study area included 11 sampling sites along the Nisava River, with one site on the Jerma River and one on the Temska River. Monthly samples (from stones, sediments and macrophytes) were collected from May 2008 to May 2009. Diatom frustules were cleaned with chemical agents, and mounted on permanent slides. In total, 194 diatom taxa were identified. The most species rich genera are Navicula (25), Nitzschia (17) and Gomphonema (13), while other genera are presented with one or more species. Detailed floristic analysis of the benthic diatom flora has not been conducted before on these rivers. Therefore, this paper provides a baseline for future research.

Floristic Analysis

The paper presents data on the composition of epilithic diatoms in the Raska River. Samples were collected by scraping stone surfaces with a brush from 5 localities along the Raska River in April, June, August and November 2011 and March and May 2012. Diatom frustules were cleaned using cold acid method, and mounted on permanent slides. An investigation of the Raska River resulted in description of 106 diatom taxa. The most species rich genera are Navicula (10), Gomphonema (10) and Nitzschia (9), while other genera are presented with one or more species. Detailed floristic analysis of the benthic diatom flora in this river has not been conducted before. Therefore, this paper provides a groundwork for future researches.
