Species Diversity of Carp, Cyprinus Carpio (Cypriniformes, Cyprinidae), Parasites in Some Cultivation Regions
Zoogeographical comparison for species diversity of carp parasites in different cultivation regions including aquatic ecosystems of Ukraine, Uzbekistan, Russia, and Vietnam was carried out. Totally, 160 parasitic species were recorded in carp within these regions. Parasitic species with direct and complex life cycles important in epizootic, veterinary, and health areas were registered.
The aim of this study was to describe the proportion of floristic geoelements and plant biodiversity in the macroregions of Transdanubia. The core data source used for the analysis was the database of the Hungarian Flora Mapping Programme. The analysed data were summarized in tables and distribution maps. The percentage of continental elements was higher in dry areas, whereas the proportion of circumboreal elements was higher in humid and rainy parts of Transdanubia. According to the climatic zones, the highest value of continental geoelement group occurred in the forest-steppe zone. The plant species diversity and geoelements were analysed also on a lower scale, with Transdanubia specified into five macroregions. The highest diversity values were found in the Transdanubian Mountain and West-Transdanubian regions because of the climatic, topographic, and habitat diversity.
Wild bees (Apiformes) were studied in 4 crop fields and 8 refuge habitats for 2 - 5 years in agricultural landscapes in the Pleven and Plovdiv regions of Bulgaria. In total, 233 bee species were recorded. Bee forage plants visited by the honey bee and wild Apiformes are listed for each refuge habitat. Species composition is given for individual habitats, including fields of alfalfa (Medicago sativa), oilseed rape (Brassica napus), sunflower (Helianthus annuus), and radish (Raphanus sativus). Species richness and dominance structure of bee communities in the 2 regions are compared, and species responsible for significant differences are identified.

The results of studies on soil ciliate diversity in different parts of the Samur-Yalama National Park undergoing human impact of different force are presented. It is shown that the highest species diversity observed in forest soils with minimal human impact. Cultivated soils in gardens and farmlands are characterized by low species diversity, often with mass development of a few dominant eurybiont species. A strong influence of land treatment on soil fauna of ciliates shown.
This treatise investigates the poorly studied bird fauna of Mitidja Plain (Northern Algeria), with particular notes on the occurrence and expansion of new and alien species. Direct observations, supported by ornithological surveys carried out by Progressive Frequential Sampling (PFS), a version of a point count method, have allowed us to identify 125 bird species. These represent 31% of all species known from Algeria. The species recorded belong to 14 orders, 39 families and 37 genera. According to their biogeographic origins, 36 are Mediterranean, 32 Palearctic, 24 Holarctic, 17 European and 16 of European-Turkestani origin. The Mitidja Plain holds 60 resident-breeder species (48% of all registered species) and is a transit zone for many migratory species (summer and winter migrants constituting 20% and 14% of the total, respectively) and occasional visitors (RA = 12%). Among recently expanding species (introduced or local), the Collared Dove Streptopelia decaocto and Wood Pigeon Columba palumbus, sampled by the spot-mapping method, experienced a very rapid population growth. The first observations of the former were made in 1996 in Algiers. Its numbers experienced a steep increase after 2002, starting from 5.75 pairs/10 ha to reach up to 31.5 pairs/10 ha in 2006. The same applies for the Rose-ringed Parakeet Psittacula krameri, surveyed by direct-count at roosting sites. This species has been able to increase and reproduce since its first introduction into the wild in 1996. The increase in study species populations, especially the Rose-ringed Parakeet, may derive from good weather conditions that favoured the species through providing better feeding conditions, thus high reproduction outcomes.
Species complexes of oribatid mites in soil and litter in 10 plots in green areas of different parts of Kyiv city in April-September 2011 were studied. In total, 107 species of 76 genera of 44 families of oribatids were found. Trends of seasonal fluctuations of species diversity and dominance structure of oribatids in studied plots were assessed.

The diversity of freshwater gastropods recorded in the Transcarpathian Region of Ukraine is reviewed and comments on their distribution and ecology are provided. Thirty-five species were revealed in samples collected from the lowland and mountainous parts of the Ukrainian Transcarpathia. Three species are recorded for the first time in the regional fauna: Viviparus sphaeridius, Bithynia troschelii and Segmentina montgazoniana. For species found in the region brief remarks on the biotopes in which they were registered and relevant taxonomic comments are given. The most distinctive features of the mollusc fauna of Ukrainian Transcarpathia are considered; the presence as well as the absence of some taxa in comparison with adjacent regions is discussed. The results of our observations confirm that the distribution of gastropod species depends on the types of waterbodies and their altitude location. The presented data contribute to the knowledge of the regional malacofauna and should help to assess the biogeographic status of the Transcarpathian Region more clearly.
This study presents the species structure of macrofungi in different plant communities formed on fallows as a result of secondary succession. The mycological observations were carried out in 2012 and 2013 in the buffer zones of all landscape parks in the Łódzkie province, i.e. Bolimów LP, Spała LP, Sulejów LP, Warta-Widawka LP, Łódź Hills LP, Przedbórz LP and Załęcze LP. The botanical research identified fallows representing 7 types of plant communities. In total 46 macromycetes species were found on the fallows. The diversity of macrofungi depended on the type of plant community. The highest number of fungi species was found in the communities with an admixture of trees (Pinus sylvestris, Betula pendula), while the lowest was collected on fallows almost completely covered by Cirsium arvense and Solidago canadensis. Considering the trophic classification of macrofungi found on fallows, most species were saprotrophic and mycorrhizal. Wood inhabiting saprotrophs were represented by only two species
