Four species of the genus Trifurcula Zeller, 1848 are described from Italy: Trifurcula (Trifurcula) aetnensis sp. n. on Genista aetnensis (Biv.) DC., T. (T.) cytisanthi sp. n. on Genista radiata (L.) Scop., both close to T. (T.) aurella Rebel, 1933; T. (T.) baldensis sp. n. on Genista radiata close to T. (T.) immundella (Zeller, 1839), and T. (T.) trasaghica sp. n. on Corothamnus decumbens (Durande) Spach similar to T. (T.) pallidella (Duponchel, 1843), but more close to T. (T.) beirnei Puplesis, 1984 and T. (T.) squamatella Stainton, 1849....

Parafomoria fumanae sp. n. is described from southern France. The new species is similar to Parafomoria ladaniphila (Mendes, 1910), but very close to P. cistivora (Peyerimhoff, 1871) and P. helianthemella (Herrich-Schäffer, 1860) after its genital morphology. It differs especially by the characters on valvae, tegumen, uncus and aedeagus. Its larva is a stem miner of Fumana procumbens (Dunal) Gr. et Godr., the species is the first stem miner in the genus Parafomoria van Nieukerken, 1983.

The methodology itself was based on assumption that the tomato growing areas are characterized by the certain minimum temperature sum required for the profitable production. It is obvious that the increase of the temperature predicted by the General Circulation Models will lead to the increase of these temperature sums over the whole area of the Czech Republic. However it is clear that not only meteorological elements but also suitable soil conditions are limiting factors for successful tomato growing. Therefore the presence of the predefined soil types was the second factor determining the suitability of the given region for the tomato growth. The...

Acta Univ. Agric. Silvic. Mendelianae Brun. 2005, 53(1), 27-34 | DOI: 10.11118/actaun200553010027
In the present study, examined was the effect of a yeast culture (Saccharomyces cerevisiae, Strain 47) on rumen fermentation of cows. Animals received a diet consisting of good maize silage with a higher dry matter content (16 kg), 16 kg of clovergrass haylage, 3 kg of meadow hay and 7.5 kg feed mixture. The yeast culture was added to the mixture in the dose 6 g/day and cow. The supplement of yeast culture showed a positive effect on VFA production in comparison with control (1.16±0.013B vs. 0.84±0.063A g/100 ml), and lower production of lactic acid. The utilisation of ammonia was higher by cows in treated...

The object of this work was to verify influence of feed and surroundings on lipids content and fatty acids spectrum in musculature of European catfish (Silurus glanis) cultivated in intensive conditions. Within years 2000-2002 feeding tests with European catfish of initial weight from 60 to 500 grams were executed. For rearing of fish recirculation system at Department of Fisheries and Hydrobiology of Mendel University of Agriculture and Forestry in Brno and facility of farm in Tisová (Czech Fisheries Company, s.r.o. of Marianské Lázně) using flow through system warmed by water from the Tisová thermal power plant were used.Feeds for salmonid...

Mugwort (Artemisia vulgaris L.) extremely spreads on uncultivated agricultural land and expands to arable land. Three sites were chosen in the local area of Uherské Hradiště: field (arable land), balk (adjacent to arable land) and rubble heap (distant from arable land). At each site, 50 plants were selected from which mature achenes were collected in 2002 and 2003. The achenes germinated in a laboratory at a room temperature and were subjected to various germination conditions. A part of them was exposed to the temperature of - 20 °C in a freezer, the other part was stored at a room temperature. The germination was carried out either on filter...

The paper deals with the evaluation of the response of spruce stands on the effect of climatic and anthropogenic factors in two localities predominantly of the 4th forest vegetation zone (fvz) of the Drahany Highland - Forest Range (FR) Proklest, Training Forest Enterprise (TFE) "Masaryk Forest" Křtiny and Forest Range Senetářov, Forests of the CR, Forest District (FD) Tišnov. The evaluation was carried out on the basis of monitoring according to the ICP Forests Programme completed by the determination of the crown structure transformation (CUDLÍN et al., 2001a). This methodology makes possible to estimate retrospective responses of a stand on the...

Soil moisture regime of floodplain ecosystems in southern Moravia is considerably influenced and greatly changed by human activities. It can be changed negatively by water management engineering or positively by landscape revitalizations. The paper deals with problems of hydropedological characteristics (hydrolimits) limiting soil moisture regime and solves effect of hydrological factors on soil moisture regime in the floodplain ecosystems. Attention is paid especially to water retention curves and to hydrolimits - wilting point and field capacity. They can be acquired either directly by slow laboratory assessment, derivation from the water retention...

The paper was aimed at the determination of variability of horizontal resin canal dimension in spruce wood in relation to the position in a spruce stem. Significant changes of dimensions in horizontal resin canal along the stem length and radius were found. On the basis obtained of results 3D models (for CW, OW, SWL and SWP zones) describing changes in resin canal dimensions in spruce in relation to the position in a stem were created. In the models, the resin canal dimension decreases with the height of a stem and on the other hand, with an increasing distance from the stem pith the dimension of resin canal increases. The importance of the paper consists...

The aim of this study was to analyse the level of feeding pea on piglets performance. In the trial the addition of pea varietas breed GOTIK with the highest content of antinutritive factors and commonly used mixture (fed in group G01) was compared. The tentative mixtures contained following amounts of pea: group G9 - 9 %, group G18 - 18 % and group G27 - 27 %.The average daily gain were: the control group G01: 0.425 ± 0.110, group G9: 0.395 ± 0.121, group G18: 0.358 ± 0.108 and group G27: 0.315 ± 0.113 kg. Out of these numbers ensues that with higher amount of pea GOTIK the average daily gain was decreasing. In the feed...

European Union deals long with problems of the two components of environment the air and the water. So far soil wasn't in the main scope of the European Union. The European Union deal now with problems of soil, where we can find question of the soil monitoring. This issue was solve in the framework of the Working group on soil monitoring (WG). The recommendations from the WG are base for deciding of the European Commission, which will have interest to formulate new soil directive. The main tasks of the WG were to review of existing soil monitoring systems, to specify basic soil parameters, indicators, to define soil parameters for each soil threats...
