For the first time, syntaxonomic diversity of steppe vegetation along Baikal-Gobi transect was determined, represented by 49 associations belonging to 23 formations, 5 florocoenotypes, and 3 ecological-historical series. The classification construction according ecological-phytocoenotic dominant-determinant principle based on data collected during field research processed using traditional geob...

Field investigation carried out by the Sicilian botanists in last 20 years enabled them to identify eight habitat types of high biogeographic and conservation interest, neglected Directive 92/43, which deserve ad hoc measures. For each these habitats, a syntaxonomic interpretation corresponding plant communities, their main ecological, physiognomic syndynamic traits list diagnostic species are ...

We propose an equation to evaluate the efficiency of a classification as function effort required and population size data collectors. The formula postulates “classification coefficient”, which relates not only complexity object be classified, but also availability representativeness. When applied phytocoenoses, suggests that system based on vascular plants offers best compromise between sampli...

background: acinetobacter baumannii is an important opportunistic pathogen which causes complications in hospitalized patients, especially those in icu. the aim of this study was to determine the frequency of class 1 and 2 integrons in multi-drug resistance a. baumannii and to investigate the association between the presence of integrons and antibiotic resistance patterns. methods: a total of 4...

Mid-field woodlots play an important role in maintaining biodiversity agricultural landscapes. However, it is not clear whether non-linear or linear are most beneficial for wild bee conservation. We assessed the attractiveness of two common types landscape northern Poland (non-linear and linear: 7 9 sites, respectively) terms abundance, species richness, functional diversity. Linear habitats ha...

this study investigated language learning styles of iranian efl learners and their class achievement. to this end, sixty female ad- vanced learners of instruction and different ages (15-30), studying at a language institute in shiraz were asked to take part in the study. a 30- item language learning styles questionnaire developed by reid (1987) was employed to elicit information for the study. ...
