AbstractThe study estimates the parameters of the photosynthesis–irradiance relationship (PN/I) of a sedge-grass marsh (Czech Republic, Europe), represented as an active “green” surface—a hypothetical “big-leaf”. Photosynthetic parameters of the “big-leaf” are based on in situ measurements of the leaf PN/I curves of the dominant plant species. The non-rectangular hyperbola was selected as the best model for fitting the PN/I relationships. The plant species had different parameters of this relationship. The highest light-saturated rate of photosynthesis (Asat) was recorded for Glyceria maxima and Acorus calamus followed by Carex acuta and Phalaris arundinacea. The lowest Asat was recorded for Calamagrostis canescens. The parameters of the PN/I relationship were calculated also for different growth periods. The highest Asat was calculated for the spring period followed by the summer and autumn periods. The effect of the species composition of the local plant community on the photosynthetic parameters of the “big-leaf” was addressed by introducing both real (recorded) and hypothetical species compositions corresponding to “wet” and “dry” hydrological conditions. We can conclude that the species composition (or diversity) is essential for reaching a high Asat of the “big-leaf ”representing the sedge-grass marsh in different growth periods.

The paper deals with the study of the radiation state of the soil and herbaceous vegetation represented by perennial grasses (Poa pratensis, Calamagrostis epigejos, Rubus saxatilis, Carex acuta, Phleum pratense) in the south of the Tyumen Region. The content and distribution of natural radionuclides in soil and herbaceous vegetation was studied in the Nizhnetavdinsky District of the Tyumen Region at the site of an underground nuclear explosion. Sampling and laboratory tests were carried out according to generally accepted methods. Soil samples were taken at the epicenter of the explosion and at the cardinal directions. Layer-by-layer sampling allowed us to study the vertical distribution of radionuclides in the soil profile. Sampling of perennial grasses was carried out at the same sampling points. Radiation studies of soil and vegetation samples were carried out on the Progress-2000 spectrometric complex. The authors have revealed specific activity of natural radionuclides (K-40, Th-232 and Ra-226) in the profile of grey forest soil in the Nizhnetavdinsky District. They have calculated effective specific activity of radionuclides in the soil. The comparative analysis of the obtained results with the data on administrative areas in the south of the Tyumen Region showed that in the soil of the Nizhnetavdinsky District specific activity of natural radionuclides is higher than in the South region in general. The specific activity of natural radionuclides in perennial grasses of the Nizhnetavdinsky District was determined, and the coefficient of accumulation of radionuclides was calculated.

Abstract Floristic composition of terrestrial and aquatic plants in the ecotopes of surface water bodies, Blue Lakes and Lake Biserovo, was studied to assess environmental health of aquatic ecosystems in the Moscow region. The research was carried out both in the field and in the laboratory. Blue Lakes were lacking aquatic vegetation and the dominant synusia of the following plant species was found along the coastal zone: meadow clover (Trifolium pratense L.), meadow bluegrass (Poa pratensis L.), sedge coastal (Carex riparia Curt.), chamomile (Matricaria chamomilla L.), plantain (Plantago major L.), Timothy meadow (Phleum pratense L.). The vegetation cover of Lake Biserovo was patchy: submerged vegetation was most widespread, Canadian Elodea (Elodea canadensis Michx.) was the dominant species. Pure thickets of vegetation were formed only by the common American water plantain(Alisma plantago-aquatica L.), lake cattail (Schoenoplectus lacustris L.), common reed (Phragmites communis Trin.) and sedge coastal (Carex riparia Curt). It should be noted that in all the studied water bodies, the pH of the water area can be classified as very clean: Blue Lakes (7.8), samples from Lake Biserov (8.32). Water samples from Lake Biserova had the highest turbidity (11.5), which was associated with the accumulation of particles of the silt fraction of the reservoir, which began the process of eutrophication, high anthropogenic load. According to the results of a comprehensive assessment (hydrological indicators, calculation of the Mayer index) of the studied samples from the reservoirs, it was concluded that the water area of the Blue Lake had the best environmental status in the Noginsk region.

Kardashynka swamp is the largest swamp not only in the Kherson region, but also in the entire steppe zone of Ukraine. According to the results of the study of the part of the Kardashynka swamp, which in 2015 became part of the Nyzhnyodniprovskyi National Nature Park and is located in the Kherson region between the villages of Kokhany of Holoprystansky and Solonets of Oleshkivsky districts, 214 species of vascular plants were recorded, which belong to 194 genera and 83 families. The leading families of flora are: Asteraceae (31 species), Cyperaceae (19), Poaceae (15), Lamiaceae (10), Fabaceae (9), Brassicaceae (8), Rosaceae (9), Caryophyllaceae (8). We have not identified the species included in the Red Book of Ukraine in the studied area. Among the regionally rare species, the growth of: Alnus glutinosa, Quercus robur, Dryopteris carthusiana, Fraxinus excelsior, Nymphaea alba, Carex lasiocarpa was observed. The basis of vegetation is compiled of: in the swamps −Alnus glutinosa (L.) Gaertn., Phragmites australis (Cav.) Trin. ex Steud., Iris pseudacorus L., Frangula alnus Mill., Typha angustifolia L., Urtica dioica L., Tephroseris palustris (L.) Rchb., Carex elata All., Carex pseudocyperus L., Hottonia palustris L. Poa bulbosa L.; in the meadows – Plantago major L., Alsine media (L.) Vill., Cerastium glutinosum Fries, Lathyrus palustris L.,; Poa bulbosa, Poa palustris L., Carex acuta L., Carex acutiformis Ehrh., Melilotus albus Medik., Trifolium arvense L., Glechoma hederacea L. Juncus effusus L., and in reservoirs - Lemna minor L., Lemna trisulca L. , Nymphaea alba L., Nuphar lutea (L.) Sm., Myriophyllum sp. Lichen biota is represented mainly by epiphytes on the bark of Salix sp. and Populus alba. On the bark of Populus alba, a typical for this area species Xanthoria parietina, Amandinea punctata, Scholiciosporum chlorococcum, Physcea adscendens, Physcia tenella are presented. Also, we note that among the priority areas for the development of nature reserves is the possibility of expanding the territories. One of such objects, which, eventually, can be included in the boundaries of NNP "Nyzhnyodniprovskyi", is the designed botanical reserve of national importance "Kardashinka swamp". The part of the territory is already included to the economic zone of NNP "Nyzhnyodniprovskyi". Key words: swamp, species, sozophytes, national nature park

The Town

The studies of natural forest vegetation of Salavat town were made during 2008–2011. 31 relevés of forest communities within the natural boundaries of phytocenoses were done. Vegetation of Salavat town includes ruderal, grass (meadow, steppe, helophyte and water vegetation) and forest vegetation. Water, helophyte, synanthropic, natural and semi-natural grass vegetation of the town was discussed in previous articles (Golovanov et al, 2011 and others). This article is devoted to the syntaxonomy of natural forest vegetation of Salavat town. Syntaxonomy of natural forest vegetation of Salavat town includes 3 classes (Querco-Fagetea Br.-Bl. et Vlieger in Vlieger 1937, Salicetea purpureae Moor in 1958 and Alnetea glutinosae Br.-Bl. et Tx. ex. Westhoff et al., 1943), 3 orders (Fagetalia sylvaticae Pawłowski, Sokołowski et Wallisch 1928, Salicetalia purpureae Moor in 1958 and Salicetalia auritae Doing 1962), 4 alliances (Alnion incanae Pawłowski, Sokołowski et Wallisch 1928, Salicion albae Soó 1930, Salicion triandrae T. Müller et Görs 1958, Salicion cinereae T. Müller et Görs ex Passarge 1961), 4 associations (Alnetum incanae Lüdi 1921, Salici-Populetum (R. Tx. 1931 ) Meijer Drees 1936, Salicetum triandro-viminalis Lohmeyer 1952, Salicetum pentandra-cinereae Passarge 1961) and 5 variants (ass. Alnetum incanae — variant Galium aparine; ass. Salici-Populetum — variants Carex acuta, Bromopsis inermis, Carex praecox and Acer negundo). Plant communities of the class Querco-Fagetea combine the broadleaf and coniferous-deciduous mesophytic forests of the temperate zone of the western Palearctic (Ermakov, 2012). One variant Galium aparine of ass. Alnetum incanae was registered in Salavat town. This variant of the association was described from the urban areas. The presence of synanthropic species such as Acer negundo, Arctium lappa, Arctium tomentosum, Artemisia vulgaris, Chelidonium majus, Convolvulus arvensis, Galium aparine, Geum urbanum, Leonurus quinquelobatus and etc. is very typical. Plant associations represent forests with Padus avium, which are often found in the floodplain of the river Belaya on the rich short-time flooded soils. The class Salicetea purpureae includes both riverine floodplain forest and shrub communities (Yamalov et al., 2012). 2 associations (Salici-Populetum and Salicetum pentandra-cinereae) and 4 variants (Carex acuta, Bromopsis inermis, Carex praecox and Acer negundo) were distinguished. The plant communities of associations Salici-Populetum and Salicetum triandro-viminalis represent the floodplain willow-poplar forests and shrubby vegetation, which are commonly found in the Republic of Bashkortostan on the river banks and lakeshores. Typically the communities are found on the banks of the river Belaya within the town of Salavat (Khaziakhmetov et al., 1989). A distinctive feature of the communities is a presence of the North American invasive neophyte species Acer negundo. Naturalization of this species takes place on the floodplains of the Republic of Bashkortostan. The similar community was recorded in Bryansk region (Bulokhov, Kharin, 2008) and they were described as the association Aceri negundi–Salicetum albae Bulokhov et Charin 2008. Our communities are different due to the dominance of Populus nigra with insignificant role of Salix alba. Further data collection can help to describe the new unit of the ecology-floristic classification. The plant communities of the class Alnetea glutinosae combine the lowland eutrophic black alder swamps, birch swamp forests and thickets of willow shrubs on peaty soils (Ermakov, 2012). The association Salicetum pentandra-cinereae was described. The association represents of hygrophyte and mesohygrophyte communities with dominance of grey willow. These communities are found on the banks of fens and oxbows in abundant moisture conditions. They are rarely found on fen mires in Salavat town.

A Duna országunk legnagyobb felszíni vízfolyása. A Duna, valamint árterei és holtágai ökológiai folyosóként működnek, de emellett jelentős ipari, logisztikai és turisztikai jelleggel is rendelkeznek. Köztudott, hogy a Duna forrásától kezdve a torkolatáig több ipari létesítmény is elhelyezkedik, amelyek szennyezése az elmúlt évtizedek alatt hatást gyakorolt a víz minőségére is. A kibocsátott szennyezőanyagok közül a legveszélyesebb összetevőket a nehézfémek jelentik, amelyek jelen lehetnek mind a vízben, mind az iszapos üledékben is. Ezek az elemek jelentős egészségügyi kockázattal rendelkeznek, hiszen képesek a táplálékláncon belül akkumulálódni. A kutatásunk fő célja, hogy a folyóvízi üledékekben található nehézfémek növényeken belüli akkumulációját meghatározzuk. Fő mintavételi területünk a Duna árterében található dunaújvárosi iszap meddő, amelyet 2009-ben hoztak létre a városi Szabadstrand rehabilitációja során. Méréseink során az üledék és növényminták kadmium, nikkel, ólom, króm, réz és cink tartalmát határoztuk meg. Tesztnövényként a területen megtalálható, természetes növényeket választottunk, mint lósóskát (lóromot) (Rumex patientia), angol perjét (Lolium perenne), parti sást (Carex riparia), és keserűfüvet (Persicaria maculosa). Az iszap és növényminták nehézfém tartalmának feltárását MSZ szabvány szerint végeztük el salétromsavas és hidrogén-peroxidos módszer alkalmazásával. A nehézfém koncentrációkat AAS készülék  segítségével határoztuk meg. Eredményeink alapján megállapítottuk, hogy a különböző növényfajták milyen mértékben és melyik részükben halmozzák fel a nehézfémeket. Eszerint például a lósóska a szárának felső részében tudja akkumulálni a kadmiumot, nikkelt, krómot és cinket, ezzel szemben a keserűfű inkább a levelében halmozza fel ezeket az elemeket. Ezek az ismeretek hozzájárulnak ahhoz, hogy a jövőben egyes növényfajták felhasználhatóak legyenek a szennyezett területek in-situ kármentesítésében.
