Salemea sororia sp. n. and Heteronychia obvia sp. n. are next two new discoveries of flesh-flies from Erico arboreae-Quercetum Ilicis formation above Trabia (Palermo). These two obviously very rare taxa were collected near the hilltop of Pizzo Onofrio-Casina (Trabia) near Palermo at 773 m a.s.l., where the flesh-flies were systematically captured in a hilltopping situation at the turn of May/June of the years 1997 -2003. In connection with the description of Salemea sororia sp. n. the complicated taxonomy, synonymy and distribution of Salemea ferox (Villeneuve, 1908) are discussed. As for Heteronychia obvia sp. n.,...

The gnorimoschemine taxa (of the gelechiid moths) Insuloschema barbarae gen. n., sp. n. and two species of the genus Keiferia Busck, 1939, viz. Keiferia educata sp. n. and Keiferia powelli sp. n. are described from California. The first taxon is obviously endemic to one of the most interesting Channel Islands called Santa Barbara and it corroborates its unique history. The two newly described species of Keiferia enrich essentially the number of species existing in California and in the Nearctic realm generally. Moths and their genitalia are figured within the description.

With the more recent knowledge, the hypothesis by Joyeux and Baer (1929) is consulted: "... most of rarer species of tapeworms occurring in man are probably parasites of other mammals, specially of Rodentia .....". In connection with that, the host specificity in several species from the families Hymenolepididae, Anoplocephalidae and Davaineidae is discussed. So far parasites of rodents are concerned, they are the species Rodentolepis straminea, R. fraterna, Hymenolepis diminuta, H. pseudodiminuta, H. hibernia and Inermicapsifer arvicanthidis. So far parasites of man are concerned, they are the species Rodentolepis...

Diets of the raccoon dog and badger were studied in the Landscape Protected Area (LPA) Litovelské Pomoraví from 2000 to 2001 by collecting faeces from latrines during March - December every year. The relative volume and frequency occurrence of each food item in the feaces were calculated. Vertebrates and invertebrates constituted the bulk of the raccoon dog diet, while plants and invertebrates were most frequently eaten by the badger. Insecta and Rodentia were important to the raccoon dog, but it also consumed other food items. The raccoon dog was more omnivorous that the badger. Badger fed very frequently on plant material, raccoon dog, instead, frequently...

The studies conducted from 1997 to 1999 in a vegetation hall were performed as a pot experiment on ordinary silt soil. Jerusalem artichoke, maize, Sida hermaphrodita Rusby, amaranth and hemp were used as indicator plants. The results confirmed, great diversification of the element contents which depends not only on the species but also on the part of individual plants. Analysis of the data revealed also another dependence: increased concentration of heavy metals in the soil corresponded to a higher content of heavy metals in the plants. Significant differences in this respect were observed for the plant species grown in unpolluted or differently...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2004, 52(1), 121-126 | DOI: 10.11118/actaun200452010121
Four-year investigations conducted as a field experiment aimed to determine the effect of organic fertilisation with farmyard manure, tannery sludge and vermicompost obtained from it on soil humus compounds composition. Equal to farmyard manure effect of vermicompost on organic carbon and total nitrogen was determined in the discussed experiment. Organic carbon content diminished as a result of mineral treatment and fertilisation with untreated sludge. The number of most mobile humus fractions decreased in result of applied fertilisation where as the share of humus compounds not undergoing hydrolysis increased.

Acta Univ. Agric. Silvic. Mendelianae Brun. 2004, 52(1), 199-204 | DOI: 10.11118/actaun200452010199
The aim of this ethological experiment was to study the effect of decreasing numbers of hens kept in cages on changes in their behaviour. The numbers of hens were reduced from three to two and one bird per cage and the results of ethological observations were as follows: in cages with three birds the behaviour of hens was relatively normal and corresponded with behaviour patterns observed in cage technologies. A reduction to two hens per cage increased their fighting activities because one of them struggled for a dominant position so that the performance of subordinated hen was usually decreased. Individual rearing resulted in attenuated feeding activities,...

Seven podzol profiles from mountain regions of the Czech Republic were studied within a research programme. Especially microscopic characters of soils and their micromorphological properties were studied in detail. In all profiles studied the separation of the soil mass into two constituting elements, viz. skeleton and plasm, was observed. In eluvial horizons mainly the structures are represented which result from a progressed dissolution of the building plasm and which contain skeleton consisting mainly of completely washy (leached) sand grains. Only very little organic matter is present in eluvial horizons. In leached (iluvial) horizons covering...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2004, 52(1), 209-216 | DOI: 10.11118/actaun200452010209
The paper presents a comparison of pulling properties of a prototype of three-axle tractor 6K6 with the classical tractor John Deere 8400. To compare differences in the contact surface of wheels the authors measured the area of tyres of tested tractors. It was found out that the contact surface of tyres of 6K6 tractor was larger by 62 % than that of John Deere 8400. Results of measurements performed on a stubble indicated that the drawbar pull force of 6K6 tractor was 70 kN while that of 4K4 only 58 kN (slippage of wheels was in both cases 40 %). It was concluded that although the weights of both tractors were comparable, a greater drawbar pull force...
