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.

Abstract

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.

Abstract

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.
