The aim of the study was to evaluate the exclusivity and/or preference of macroinvertebrate taxa for river habitats. Indicator species analysis and random forests methods were applied to the data set of macroinvertebrate samples taken from 58 sampling points. Samples were classified according to habitat types defined by the position in a river channel and(More)
The effect of environment and species dispersal limitations may both significantly affect the structure of ecological metacommunities but there have been a relatively few attempts to separate their effects in aquatic assemblages. In this paper, we tested the relative importance of environment and space on the ostracod assemblages on a regional scale(More)
The diversity of spring habitats can be determined not only by local environmental conditions, but also by large-scale biogeographical effects. The effects can differ across various groups of organisms. We compared α-, β- and γ-diversity patterns of bryophytes and vascular plants of (sub)alpine springs in three contrasting mountain ranges: Alps(More)
The aim of the present study was to estimate the extent to which macroinvertebrate assemblages in a headwater stream are determined by environmental conditions and temporal dynamics. Six mesohabitats defined by substratum were sampled monthly throughout one year, environmental conditions at each sampling point being precisely described. Environmental(More)
Grass meal is as good as the grain components by its nutritional value, but excels them in nutritional value of protein and vitamins. One kilogram of the grass meal contains 0.7–0.8 feed units, 16–18% of the digestible protein, and up to 30 mg of carotene. During the high-temperature drying of the green material of the perennial grasses, these indices can(More)
Technological and technical advantages of high-temperature treatment of fodder grain and mixed feeds are presented; they allows us to significantly reduce the exposure of thermal treatment of feeds, exclude energy-intensive processes, simplify production flowcharts, and use the exhaust steam for preheat processing of raw materials, which are being(More)
A production line is proposed for micronization of fodder grain with a capacity up to 10 t/h, where superheated steam is used as a heat-transfer agent, the specific heat capacity of which is 4 times higher than that of air and thermal conductivity is 23 times higher. The combined effect of high temperature and pressure reduce manyfold the treatment time and(More)
Environmental factors driving compositional changes of headwater aquatic assemblages have been widely studied as these habitats are among the most vulnerable environments and host diverse and species-rich assemblages. However, responses of individual species to multiple environmental gradients remain poorly known, despite such information being essential(More)
Infection with Fascioloides magna (Digenea) causes serious damage to liver tissue in definitive hosts represented by ruminants, especially cervids. The distribution of F. magna includes the indigenous areas in North America, and the areas to which F. magna was introduced—Central Europe, Southeast Europe, and Italy. The North American intermediate host of F.(More)
