Synura lapponica Skuja, a freshwater colonial flagellate (Synurophyceae, Stramenopila), has been reported for the first time in the Czech Republic. This study evaluates the ecological requirements of the species, and includes a survey of the literature. Although S. lapponica has been reported thus far only in the Northern Hemisphere, the probability of its bipolar distribution is relatively high...
Distribution data on Cardamine amara L. in Serbia and Republic of Macedonia are presented, together with a short review of the history of taxonomic treatment of C. amara in this area. C. amara subsp. balcanica Marhold, Ančev & Kit Tan is reported as a new taxon both for the flora of Serbia and flora of Republic of Macedonia and the occurrence of C. amara subsp. amara in Serbia was confirmed.
Cocaine administration in the brain alters gene expression via dopamine and glutamate receptor-mediated intracellular signaling cascades. The current study was designed to identify alterations in the total proteome in the rat dorsal striatum in response to intraperitoneal injection of cocaine (20 mg/kg). The results demonstrated that alterations of specific proteins at 20, 120, and 360 min following...
Chablisea concave sp. n. and C. Varicolor sp. n. from China are described and illustrated. A key to the world species of the genus is provided. Type specimens are deposited in the Parasitic Hymenoptera Collection of Zhejiang University, Hangzhou, China (ZJUH).
Possibility to improve plantlet regeneration from Abies alba Mill. open-pollinated families of 4 trees in Dobroč primeval and 3 trees in managed forest was studied. Immature zygotic embryos were cultured in order to obtain initiation of embryogenic tissue. Totally, three from the families of the managed forest (57%) and two from the primeval families (50%) responded to initiation condition. Initiation...
During a mark-recapture study of Parnassius mnemosyne butterfly, we recorded incidence of females bearing or not bearing sphragis, a waxy structure delivered by males during copulation and preventing subsequent inseminations by other males. Despite the common belief that sphragis ensures monopolisation of females, we observed that 74 out of 579 marked females did not bear sphragis at a time of capture...
An Indonesian marine bacterial isolate, which belongs to genus of Bacillus sp. based on 16S rDNA analysis and was identified as Bacillus filicolonicus according to its morphology and physiology, produced a raw starch degrading α-amylase. The partially purified α-amylase using a maize starch affinity method exhibited an optimum pH and temperature of 6.0 and 60°C, respectively. The enzyme retained 72%...
To develop a plant expression system for the production of the chicken interferon gamma (ChIFN-γ) oral vaccine adjuvant, we investigated whether the ChIFN-γ protein can be expressed in tobacco plants. The coding sequence of the ChIFN-γ gene was optimized by modification of codon usage to that of tobacco plant genes. A synthetic ChIFN-γ gene was inserted into plasmid pSW-IFNG containing the CaMV35S...
Bark beetles (Coleoptera: Scolytidae) infesting Norway spruce trees are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis. However, very little is known about these fungi in Poland. In this study, we examined the ophiostomatoid species associated with seven species of bark beetles developing in Norway spruce (Picea abies). Fungi were isolated from the...
In the framework of a recent review of the systematics and global diversity of the freshwater mussel species in Tunisia, the species Unio gibbus Spengler, 1793 has been recorded for the first time. This overlooked Unio species inhabits several rivers in North of Tunisia, Northwest Morocco and Southwest Spain. Shell characters were examined in adult and juvenile specimens from several North Tunisian...
Karyological studies have been investigated within 8 native Anatolian populations of oriental spruce (Picea orientalis (L.) Link) in Turkey. The somatic chromosome number of 2n = 2x = 24 has been observed in all accessions. The karyotypes are generally asymmetrical with most of the chromosomes having median to median-submedian centromeres. Inter-population variability of the karyotype was summarized...
The rotifer community structure may be shaped by a variety of environmental factors, including biological parameters, such as predation or competition, as well as by physical-chemical factors, among which the kind of macrophyte substratum and parameters relating to the trophic state and to the catchment area conditions are of great importance. Another impact on rotifer composition, abundance and frequency...
We have studied the effect of Al on growth and morphology of maize seedlings (Zea mays L.), the changes in organic acid content as well as the role of application of exogenous citrate in enhancing the Al tolerance. Al treatment induced inhibition of root growth, causing morphological symptoms of Al toxicity. Al decreased significantly the malate content in roots compared to control plants. However,...
The effect of plot size was tested on heterogeneous and homogeneous data sets that were obtained by sampling grassland and forest vegetation on plots differing in size. Mean EIV for relevés revealed no differences among data sets from various plot sizes or between homogeneous and heterogeneous data sets. This is probably due to a similar indicator value for species newly occurring in plots with increasing...
The purpose of this study was to find out whether a set of habitat characteristics, derived from the National Corine Land Cover (CLC) database of habitat types, could indicate the occurrence of white stork nests in a settlement. The analyses were performed for the settlements closer than 35 km from the Drava River (northern Croatia). Sixteen habitat characteristics were determined around 257 settlements...
The spatial distribution and seasonal dynamics of the crustacean zooplankton were studied in the Danube River and in its side arms near Budapest, Hungary. Microcrustaceans were sampled biweekly from October 2006 to November 2007 at eleven sites. Thermocyclops crassus, Moina micrura and Bosmina longirostris added up to 57.6% of the total density. Comparisons of the different water bodies stressed the...
A new species, Balaustium biscutalae sp. n., from the southeast of Spain is described and illustrated. It was captured in two different sampling sessions from the semi-desert area in the province of Almeria, Andalucia. The new species is easily differentiated from all the other species of the group by the presence of two pairs of scutalae on the scutum instead of three.
The seed coat morphology of 10 Campanula species from Turkey, 3 of which are endemic, was studied using scanning electron microscopy. Characteristics of the seeds and their surface morphology were described and compared. Two different types were described based on seed surface features. The Type 1 seed surface was characterized by a reticulate pattern; only C. Olympica belonged to this type. The Type...
The present study was undertaken to investigate the protective effect of Indian honey on acetaminophen induced oxidative stress and liver damage in rat. Honey serves as a source of natural medicine, which is effective to reducing the risk of heart disease, liver toxicity and inflammatory processes. The hepatoprotective activity of the Indian honey was determined by assessing levels of Serum transaminases,...
