AbstractComposition and vertical distribution of soil nematode communities within soil profile were investigated in eight hop gardens in Czech Republic. In total, the presence of 78 nematode genera was confirmed. Genus Drilocephalobus (Coomans & Coomans, 1990) is new for fauna of the Czech Republic. The highest abundance of soil nematodes was found at a depth of 0–10 cm and declined with increasing depth of soil profile. The most dominant genus was Bitylenchus, followed by genera Acrobeloides, Ditylenchus, Chiloplacus and Cervidelus. Ten genera of plant parasitic nematodes were recorded: Bitylenchus (with prevalence of B. dubius), Helicotylenchus, Heterodera (with absolute prevalence of H. humuli), Geocenamus, Longidorella, Longidorus (only L. elongatus), Merlinius (with prevalence of M. brevidens), Paratylenchus and Pratylenchus. Low population densities of predators and omnivores, low values of the community indices (MI, ΣMI, SI, and CI), and high values of NCR, EI, and PPI/MI ratio indicated disturbed nematode communities in hop gardens and bacteria-dominated decomposition pathways in the soil food web.

AbstractPrevalence and intensities of excretion of Strongyloides papillosus eggs were determined in a highland area of South Bohemia (Czech Republic) in cattle of beef herds under three types of management systems (pasture, semipasture, cowshed during winter season). Strongyloides papillosus infection was found on 6 of 9 examined farms and from the 1902 fecal samples, 4.3 % were positive. Eggs excretion intensities were generally low. The high prevalence (57 %) and high intensities of excretion (more than 5.000 EPG) were found on one cowshed farm associated with 25 % mortality of calves without previous clinical signs was observed. Pulmonary pathological changes caused by migration of larvae were histologically characterized as suppurative granulomatous inflammation with young connective tissue and predominance of eosinophils in inflammatory infiltrates. The cause of death of calves was determined as the sudden death syndrome.

AbstractIn the world scale, there are various forms of how the hunting tourism is carried out. there is a considerably specific situation in the czech republic originating in the historical development. the assessment of the diversification of the demand for tourist activities was chosen to be the aim of this article. this assessment is based on a questionnaire survey among tourism participants who consume the specific products of the hunting tourism in the tourist regions of Bohemian Forest and south Bohemia. A guided tour in a game enclosure with a professional commentary and wildlife observation showed to be the most interesting offer. the most important thing is the identification of five main segments of demand called “ordinary” gamekeeper's hunting, “occasional” gamekeeper's hunting, angling activities, hunting without the killing and complementary activities. the differences among the latter five segments were identified in the representation of respondents as far as their gender and their membership in a community of anglers or gamekeepers are concerned.

This paper analyses the need to deal with the issue of financial literacy and financial knowledge not only by adults, but also by youth and young adults. This paper is focused on research into the knowledge and understanding of the financial literacy of young people, mostly between the ages of 16 to 33 years, via a questionnaire. The survey, undertaken in the Czech Republic, is based on a sample of 329 students from high schools and 329 students from the University of South Bohemia in České Budějovice [658].
