On the territory of the Ulyanovsk region upland sphagnum bogs are rare plant communities. For the first time a description of the flora upland sphagnum bogs Mokhovoe 1.5 km south of the r.p. Glotovka Inza district of the Ulyanovsk region. This is valuable in the Ulyanovsk region mount, oligotrophic bogs with birch and shrub-cotton grass-sphagnum phytocenoses not previously been studied by experts. For the first time we present data on the flora of the object. Found 20 species of plants, of which 4 (Utricularia vulgaris L., Chamaedaphne calyculata (L.) Moench., Охусоссus palustris Pers., Drosera rotundifolia L.) are included in the Red book of the Ulyanovsk region, and 3 types (Chamaedaphne calyculata, Охусоссus palustris и Drosera rotundifolia) are relic. Of particular interest is the vegetation quagmire, which is located in the center of the marshes and the water is separated from the main beach. It is here preserved valuable boreal complexes having great scientific interest. Total flora quagmire are 11 species of vascular plants, including rare and medicinal species Eriophorum vaginatum L., Сarex lasiocarpa Ehrh., Menyanthes trifoliata L. and Comarum palustre L. Dominated by two associations: Betula pubescens +Chamaedaphne calyculata +Eriophorum vaginatum + Sphagnum and Сarex lasiocarpa + Eriophorum vaginatum + Охусоссus palustris + Sphagnum. To preserve this unique natural site with rare plant species and communities needs careful protection at the regional level. Swamp Mokhovoe recommended to us for inclusion in the protected areas of the Ulyanovsk region.

This paper presents the results of a pilot field study, conducted in July 2007, designed to make floristic evaluation of the peat bog area adjacent to the western shore of Lake Bikcze (Łęczyńsko-Włodawskie Lakeland). The main aim of the study was to confirm the occurrence of populations of rare and legally protected plant species in this area and to identify, on a preliminary basis, habitat conditions in their stands. The occurrence of populations of the following strictly protected plant species: <i>Betula humilis</i>, <i>Salix lapponum</i>, <i>Salix myrtilloides</i>, <i>Carex limosa</i>, <i>Drosera intermedia</i>, <i>Drosera rotundifolia</i>, <i>Dactylorhiza incarnata</i>; and partially protected species: <i>Menyanthes trifoliata</i>, has been confirmed in the studied peat bog. Both an investigation of abiotic factors, conducted <i>in situ</i>, and an analysis of the species composition of the flora in terms of habitat preferences of particular groups of taxa have shown that the described rare plant species find suitable conditions for their growth and development in the studied peat bog.

<p>The mycology of peatlands, with their specific plant communities and numerous rare plant species, has been underexplored and is poorly recognized. The main objectives of this study were to identify the species richness and diversity of macromycetes in raised and transitional bogs of Pomerania and to establish correlations between macroscopic fungi and peatland communities occurring in the area in view of environmental conditions. Investigations spanning a period of ten years were conducted at 134 sites (71 raised and 63 transitional bogs) in eight non-forest peatland communities (<em>Caricetum lasiocarpae</em>, <em>Caricetum limosae</em>, <em>Caricetum rostratae</em>, <em>Eriophoro angustifolii-Sphagnetum recurvi</em>, <em>Rhynchosporetum albae</em>, <em>Erico-Sphagnetum medii</em>, <em>Sphagnetum magellanici</em>, and the <em>Eriophorum vaginatum-Sphagnum fallax</em> community) and two forest communities (<em>Vaccinio uliginosi-Pinetum</em> and <em>Vaccinio uliginosi-Betuletum pubescentis</em>) in which 108 permanent observation plots were established for detailed examinations. A total of 191 macromycete species were recorded in the peatlands. The smallest number of species was recorded in <em>Rhynchosporetum albae</em> (12 species) and <em>Caricetum rostratae</em> (15 species). Phytocoenoses richest in fungi were <em>Vaccinio uliginosi-Pinetum</em> (102 species) and <em>Vaccinio uliginosi-Betuletum pubescentis</em> (121 species). The number of macromycete species recorded in individual peatland communities depends on the community type and is not conditioned by the number of observations and the number and the total area of permanent plots. Five mycosociologico-ecological groups of macroscopic fungi were distinguished based on numerical analyses. Four groups comprise species of fungi associated with a specific phytocoenosis or a group of phytocoenoses. One group consists of fungi with a broader ecological scale. The majority of environmental variables representing the substrate’s chemical properties, humidity and pH show a statistically significant influence on the diversity of macroscopic fungi species in the peatland communities. Cartogram maps of the distribution of 21 species of peatland fungi are included and geographico-ecological features of the species are briefly described.</p>

Marine halophytes are an outstanding reservoir of natural products and several species have anti-infectious traditional uses. However, reports about their potential use against neglected tropical ailments, such as Chagas disease, are scarce. This work evaluated for the first time the in vitro anti-Trypanosoma cruzi activity of extracts from the aromatic and medicinal species Helichrysum italicum subsp. picardii (Boiss. & Reut.) Franco (Asteraceae, everlasting) and Crithmum maritimum L. (Apiaceae, sea fennel). For that purpose, decoctions, tinctures, and essential oils from everlasting’s flowers and sea fennel’s stems, leaves, and flowers were tested against intracellular amastigotes of two T. cruzi strains. The extract from the sea fennel flower decoction displayed significant anti-trypanosomal activity and no toxicity towards the host cell (EC50 = 17.7 µg/mL, selectivity index > 5.65). Subsequent fractionation of this extract afforded 5 fractions that were re-tested in the same model of anti-parasitic activity. Fraction 1 was the most active and selective (EC50 = 0.47 μg/mL, selectivity index = 59.6) and was submitted to preparative thin-layer chromatography. One major compound was identified, falcarindiol, which was likely the one responsible for the observed anti-trypanosomal activity. This was confirmed using a commercially sourced molecule. Target-fishing studies showed falcarindiol as a ligand of T. cruzi spermidine synthase, pointing to a potential enzyme-inhibiting anti-trypanosomal mechanism of action. Overall, this work shows that sea fennel can provide effective anti-parasitic molecule(s) with potential pharmacological applications in the treatment of CD.

This report presents the epidemiological situation of brucellosis in the Ulyanovsk region. In the territory of the Ulyanovsk region brucellosis in humans for the first time was reported in 1950. For nearly forty years only chronic cases of brucellosis among the professional groups of population (breeders, veterinarians, meat processing plant personnel) were recorded, that confirms the professional nature of the disease. At the same time on a relatively calm background sporadic cases of brucellosis detected in both acute (1996), and subacute form (2005) in children are revealed. This confirms the position that the activity of the epidemic process in zoonotic infections is influenced by both biological (especially the pathogen and the immunological reactivity of human and animal), and social factors (the system of arrangement of epidemiological-epizootological supervision on the territory).

AbstractA rich assemblage of various marine taxa from the lower Carnian Polzberg Konservat-Lagerstätte near Lunz am See (Northern Calcareous Alps, Lower Austria) is described for the first time in detail. The fossiliferous layers were deposited during the Julian 2 Ib (Austrotrachyceras austriacum Zone, Austrotrachyceras minor biohorizon). The fine-laminated Reingraben Shales comprise abundant and well-preserved members of the marine Carnian food chain. Invertebrates with the bivalve Halobia, the ammonite Austrotrachyceras and the coleoid Phragmoteuthis dominate over vertebrate actinopterygian fishes. Fragile groups such as polychaetes and isopods are entirely preserved as soft body fossils. The diverse assemblage comprises ammonites (Austrotrachyceras, Carnites, Sageceras, Simonyceras), coleoids (Phragmoteuthis, Lunzoteuthis), bivalves (Halobia), gastropods (caenogastropods/heterobranchs), one echinoid, thylacocephalan arthropods (Austriocaris), crustaceans (the decapod Platychela and isopods such as Obtusotelson, Discosalaputium), polychaetes (Palaeoaphrodite sp., eunicid polychaete), acytinopterygians (Saurichthys, Polzbergia, Peltopleurus, Habroichthys), cartilaginous fishes (Acrodus), coelacanth fish (“Coelacanthus”), a lungfish (Tellerodus), and a conodont cluster (Mosherella). Regurgitalites produced by large durophagous fish and coprolites produced by piscivorous actinopterygians accompany the Polzberg palaeobiota along with rare plant remains (Voltzia). The entire fauna of Polzberg and the excellent preservation of the specimens present a window into the Upper Triassic assemblage and palaeoenvironment during the so-called Carnian Pluvial Episode (CPE) in the early Mesozoic. The occurrence of the freshwater lungfish Tellerodus and the branchiopod Eustheria, a member of brackish to freshwater environments, points to the influence of occasional freshwater pulses or sediment transport events on the marine environment. The Polzberg palaeobiota was deposited during the global CPE, triggering the environmental conditions of the Polzberg Basin and resulting in the formation of the Reingraben Shales with the Polzberg Konservat-Lagerstätte.

Menyanthes Trifoliata

"Torfeno Branishte" is a Reserve located in "Vitosha" Natural Park, Bulgaria. It was established in 1935 to preserve the peat communities in the high parts of Vitosha Mountain in their natural state. The reserve comprises Bulgaria’s most significant complex of high mountain peatlands. Their age is estimated to be over 1500 years old, and the thickness of the peat cover accumulated during that time can reach up to 2 meters in depth. Their current area is 785.3 hectares. Plant communities dominated or participated by Sphagnum L. and/or other peat-forming mosses are very sensitive to climate change and anthropogenic impact. They often house a large number of plant species with conservation significance. The purpose of this study is to provide new data on the distribution of three extremely rare and endangered plant species. During a field study in "Vitosha" Natural Park related to the selection of sites for monitoring and installation of permanent monitoring sites for climate change monitoring in nature reserve "Torfeno Branishte", two species were found that were considered extinct from the territory of the mountain – Menyanthes trifoliata L. and Carex limosa L. Both species are protected by the Biological Diversity Act and are included in the Red Data Book of Republic of Bulgaria (Peev 2015). Prior to this study, for decades they have been purposefully searched for with no positive result. As a result of this study, the number and population sizes of M. trifoliata and C. limosa were determined. In addition, the populations of Comarum palustre L. and Carex limosa L. that occur at the same location were found to be much larger than previously known. Population sizes of the three species are low, but still viable. The major threat to the well-being of these species is the drought.

Modern problems in the agricultural sector are rooted in the fact that for decades the state agricultural policy was characterized by neglect of the interests of the main producer, non-economic coercion to labour, alienation from the land and produced goods, infringement of social rights of the peasantry which inevitably led to urbanization, population migration from villages. On the basis of the study of the scientific literature and archival documents which have been analysed for the first time, the complex process of destruction of the collective farmerss attitude to work in the public sector is explored. According to the author, the material difficulties of rural society in the war years led to the recovery in the agricultural society of previous forms of economic activity, namely the one-man operation in its stead. The victorious conclusion of the war led to the restoration of the pre-war state policy in the field of agriculture, but farmers continued to ignore social work. The author believes that public campaigns aimed at the restoration of collective farmerss labor discipline were unsuccessful because in the absence of material incentives the collective farmers were not ready for selfless labor in social production.

The paper presents the investigation data of 6 cut-over peat lands in central area of Kirov Region (on the example of Zuev, Orichev, Slobod, Kirov and Chepez areas). The authors found the new locations of 10 rare plant species enlisted in the regional Red Book and species that have limited distribution in a region or have narrow ecological range ( Gymnadenia conopsea, Dactylorhiza fuchsii, Epipactis helleborine, Epipactis atrorubens, Platanthera bifolia, Trichophorum alpinum, Botrychium multifidum, Dryopteris cristata, Thelipteris palustris, Huperzia selago ). They also describe the process of phytocoenoses. The study shows the development of new typical boggy plant societies as a result of secondary bogging (on the example of Trichophorum alpinum , Drosera rotundifolia , Carex nigra , Eriophorum vaginatum , Parnassia palustris ). The paper estimates the state of rare species populations. The authors analyze the ability of the species to inhabit artificial landscapes and anthropogenically modified phytocoenoses. That shows an explerent component of ecological-phytocoenotic strategy. Secondary boggy landscapes can play the role of refugiums for the species which habitats were lost due to industrial impact.

This work aimed to investigate the richness of a Tunisian xerohalophyteFrankenia thymifoliaaerial and root parts on phenolics and to evaluate the antioxidant and neuroprotective properties of this medicinal species. After fractionation using increasing and different solvent polarities, results displayed five fractions, where ethyl acetate (EtOAc) shoot and root fractions possess considerable total phenolic contents (221 and 308 mg of GAE/g of E, resp.) related to their important antioxidant activities such as ORAC (918 and 713 mg of TE/g of E), DPPH (282 and 821 mg of TE/g), and ABTS (778 and 1320 mg of TE/g) tests. Then, the identification of the main compounds by HPLC-DAD-ESI-MS and neuroprotective property of the most active fraction EtOAc were assessed. A total of 14 molecules were identified, which have been described for the first time inF. thymifolia. The major compounds identified were pinoresinol and kaempferol glycoside in aerial parts and gallic acid and ellagitannin in roots. Neuroprotective capacity againstβ-amyloid (Aβ) peptide induced toxicity in PC12 cells of EtOAc fraction showed a significant protective activity at lower concentration (25 and 50 µM). The relevant antioxidant and neuroprotective activities ofF. thymifoliaEtOAc fraction corroborated their chemical compositions.

Protected plant species of forest, lakes and peatbogs in the Western Part of the Drawskie Lakeland A floristic study of forest communities, lakes, and peatbogs of the western part of the Drawskie Lakeland was carried out in 2006-2008. The study revealed the presence of numerous valuable plant species. More than 400 floristic lists were compiled. Plant surveys were conducted with the aid of the ATPOL square grid system. To increase the accuracy of the surveys, the basic ATPOL squares (10x10 km) were additionally subdivided into smaller ones of 1x1 km. The area of study was found to support 416 plant species, including protected ones: 17 species strictly protected (e.g., Blechnum spicant, Dactylorhiza incarnata, Drosera rotundifolia, Lycopodium annotinum, Utricularia intermedia) and 12 under partial protection (e.g., Frangula alnus, Menyanthes trifoliata, Ononis spinosa, Ribes nigrum, Viburnum opulus). The list of protected plants contains one species (Lobelia dortmanna) included in the Polish Red Book of Plants.
