A phosphate solubilizing and antagonistic bacterial strain, isolated from a Western Ghat forest soil in Kerala province, India (designated as NII-0906), showed cold tolerance and grew from 10 to 37°C (optimum temperature 30°C). It was a Gram-positive, rod shaped, 0.8–1.6 μm in size, and exhibited tolerance to a wide pH range (5–12; optimum 7.0) and salt concentration up to 7% (w/v). The isolate showed...
Salvia macrochlamys Boiss. & Kotschy, which belongs to sect. Salvia Hedge, is a perennial herb usually growing on rocky limestone slopes in eastern Anatolia. In this study, the anatomical features of the root, the stem, the leaf and the petiole, as well as micromorphological characteristics of the pollen and the nutlet of this species have been investigated using Scanning Electron Microscopy...
We extracted, amplified and sequenced DNA from historical herbarium specimens and silica-dried samples of the fern genus Lindsaea in order to study the sequencing success between the two kinds of samples. High quality sequences were obtained from 57% of the herbarium samples. The specimens age was found to be of little importance for sequencing success when less than 75 years, but the colour of a...
Human mesenchymal stromal cells were isolated from the bone marrow of patients with polycyteamia vera (the myeloproliferative disorder) with the aim to characterize the properties of the mesenchymal stromal cells originating from the pathologically affected bone marrow. Their in vitro growth and potential to differentiate were determined. Isolated mesenchymal stromal cells were able to differentiate...
The virulence and transmissibility of viruses are highly associated with their binding specificity to the host cell receptor. In influenza, this initial event of viral pathogenesis is mediated by a glycoprotein known as hemagglutinin (HA). In the present study we constructed homology models of the chain A of hemagglutinin (HA1) of 2009 swine influenza strain. The modeled proteins were compared with...
Taraxacum pieninicum Pawł. (Asteraceae) is an endemic species, growing only in Pieniny Mts. The aim of the presented work was to investigate its pollen morphology as well as its ultrastructural traits of achene pericarp. Pollen grains of this species were of medium size, echino-lophate and 3-zonocolporate. The external surface of the achene body was of scale sculpture, covered with the spikes. Pappus...
This study investigates the diel vertical distribution and the diet of the most important chaetognath species found in the 0–50 m surface layer of a coastal area in the eastern Mediterranean during a 24-hour period in July 2004. Among the recorded chaetognaths, Sagitta enflata was the most abundant species (41.6%), followed by S. minima (32.5%) and S. serratodentata (20.8%). Those three species exhibited...
The structure and demographic processes were compared in shrub communities to test the effects of vegetation succession on population growth, fecundity and abundance of the dwarf birch (Betula nana L.), which is a rare and endangered plant species in Poland and a glacial relict in Central Europe. The effects of Ledum palustre L. and Vaccinium uliginosum L. were studied in the Linje nature reserve...
Mixed communal roosting of Montagu’s harrier Circus pygargus in the pre-laying period was observed on Calcareous Marshes in Eastern Poland from 1992 to 1995. To my knowledge, this behaviour was described in literature for the first time. The communal roosting in Montagu’s harrier during courtship can help in estimation of mate attraction and finally in mate choice. Harriers from communal roosts start...
Ontogenetic changes and temperature dependency of respiration rate were studied in Dendrobaena mrazeki, an earthworm species inhabiting relatively warm and dry habitats in Central Europe. D. mrazeki showed respiration rate lower than in other earthworm species, < 70 μl O2 g−1 h−1, within the temperature range of 5–35°C. The difference of respiration rate between juveniles and adults was insignificant...
β-1,3-1,4-Glucanase has been broadly used in feed and brewing industries. According to the codon bias of Pichia pastoris, the Bacillus subtilis MA139 β-1,3-1,4-glucanase gene was de novo synthesized and expressed in P. pastoris X-33 strain under the control of the alcohol oxidase 1 promoter. In a 10-L fermentor, the β-1,3-1,4-glucanase was overexpressed with a yield of 15,000 U/mL by methanol...
Relative resistance of paddy varieties to the Angoumois grain moth, Sitotroga cerealella was investigated in the laboratory at a temperature of 28 ± 1.0°C and relative humidity of 65 ± 1.5%. The study was carried out on Indian Agricultural Research Institute (IARI), New Delhi, India varieties and a Taiwan variety. The larvae of S. cerealella were allowed to feed and developed inside the grain while...
This study examines the impact of canopy and canopy gaps on the development of lower forest layers in five protected phytocoenoses of oak-hornbeam habitats (natural and regeneration stands) and oak-pine habitats in the Wielkopolska National Park (WPN). In the studied forests the most common form of dead trees are those which are uprooted (45–59%), while the most frequently dying tree is pine (40–88%)...
As part of our ongoing alternative medicine program, we have directed our attention toward the identification of edible seaweeds in Korea. Here we report on the anti-inflammatory activities of Ecklonia stolonifera. The present study was undertaken to elucidate the pharmacological and biological effects of E. stolonifera extracts on the production of inflammatory mediators in macrophages. The results...
We studied the influence of habitat and increased mineral phosphorus and nitrogen loading on the extracellular activity of five selected hydrolases and pH in the trap fluid of the aquatic carnivorous plants, Utricularia vulgaris, U. australis, and U. foliosa (Lentibulariaceae). Enzyme activities in the trap fluid were determined using fluorometry. Phosphatase exhibited the highest activities in the...
A new species, Anatrichus bimaculatus sp. n. (Diptera: Chloropidae), is described from Zambia. Two African Anatrichus species, A. bimaculatus sp. n. and A. erinaceus, are characterized, and the main differential features are illustrated.
The heritable elytral colour/pattern polymorphism of Philaenus spumarius in north-western Black Sea region of Turkey was investigated. A total of 2,530 adult spittlebugs, 1,020 females and 1,510 males were collected and analysed in terms of the 11 most common colour forms. Nine different phenotypes, expressed by six different alleles, were determined: populi (POP), typicus (TYP), trilineatus (TRI),...
The production of vigorous and die-back sites of the same reed belt and nutrient content of reed were studied to detect possible causes of reed die-back. Shoot density, total aboveground and belowground biomass and their C, N, P and S contents were also determined. Samples were collected from three vigorous and three die-back sites of Lake Fertő/Neusiedler See in 1996 and 1997. Reed stands were compared...
Plant communities in which the herb layer is dominated by Vellozia crinita were surveyed in seven mountain ranges with a complex comprising open herbaceous or savanna-like montane vegetation overlying quartzite and sand, locally known as “campos rupestres” in the State of Minas Gerais, southeastern Brazil, by means of 92 vegetation relevés (totaling approx. 4629 m2). Vellozia crinita displayed a growth...
Methods of numerical taxonomy, i.e. Cluster Analysis, Principal Component Analysis (PCA), Discriminant Function (DF) and Correspondence Analysis (CA), have been used to analyse 132 Operational Taxonomic Units of Potentilla subsect. Collinae. Among 53 morphological characters (20 quantitative and 33 qualitative), the most useful appeared following: bent inflorescence, flower diameter, width of epicalyx...
