Since 2011, a unique project studying the effect of artificial canopy opening (Small-size clearings) on biodiversity in lowland forests has been carried out in the Podyjí NP. The response of communities of butterflies, moths, epigeic, floricolous and saproxylic beetles, birds, reptiles, and vascular plants was observed for three years. The results showed a positive effect of early stages in forest succession not only for the majority of groups studied, but also for many threatened species, and also demonstrated the importance of open forest remnants for biodiversity. In protected forests at low and middle elevations, conservation management should attempt to maintain a mosaic of forest at different stages of succession. and Pavel Šebek a kolektiv autorů.
The moths belong to the best-studied groups of insects in the Podyjí NP. In total, 2250 species of butterflies and moths (Lepidoptera) have hitherto been recorded here. Many species are closely associated with rocky steppe and heeathland, the most valuable natural habitats in this terriotory. Concurrently, the Podyjí NP is located on the western distribution border of many eastern and southern species. On the other hand, a total of 13 species of butterflies and moths have now become extinct here. and Jan Šumpich, Jan Liška, Zdeněk Laštůvka.
The main objective of the management of woodland in the Podyjí National Park (NP) is to allow natural processes and support biodiversity. How the woodland has changed since designation of the NP is illustrated by changes in selected parameters (tree species composition, proportion of dead wood etc.). Some active measures to support woodland biodiversity are also presented in the paper. and Jaroslav Ponikelský a kolektiv spoluautorů.
The Podyjí NP has very diverse vegetation which results in the occurrence of rich butterfly communities. To date, 142 species of butterflies have been recordeed in this area, of which 19 species (13 %) are considered regionally extinct and three species (2 %) are only migrants, not native to the Czech fauna. The main cause of the decline in butterflies is the abandonment of traditional techniques of habitat management. To conserve and support butterfly diversity, the NP authority practices a wide range of management measures. and Milan Švestka.
The creation of Czechoslovakia in 1918 was the culmination of the long struggle of the Czechs against their Austrian rulers and of the Slovaks against their Hungarian rulers. At the outbreak of World War I, the Czechs and Slovaks showed little enthusiasm for fighting for their respective enemies, the Germans and the Hungarians, against fellow Slavs, the Russians and the Serbs. In 1916, together with Edvard Beneš and MIlan Rastislav Štefánik, Masaryk created the Czechoslovak National Council. In early October 1918, Germany and Austria proposed peace negotiations. On October 28, the National Committee issued a declaration of Czechoslovak independence. and Ivan Šedivý.
Odlupováním vrstevnatých materiálů (např. grafitu) lze připravit 2D krystaly s tloušťkou jednoho nebo několika málo atomů. Nejznámějším takovým 2D materiálem je grafen (monovrstva grafitu), nicméně v současnosti existují a intenzivně se zkoumají desítky podobných struktur. Příspěvek podává základní přehled o 2D materiálech, jejich vlastnostech, metodách přípravy a možných aplikacích., Layered materials (such as graphite) can be exfoliated to produce 2D crystals with a thickness of one of just a few atoms. The best known 2D material is graphene (monolayer of graphite), yet there are tens of similar structures, which are being studied intensively at the moment. This article presents a brief summary of 2D materials, their properties, methods of preparation and potential application., Zdeňka Hájková, Martin Ledinský, Matěj Hývl, Aliaksei Vetushka, Antonín Fejfar, Jaroslava Řáhová, Otakar Frank., and Obsahuje bibliografické odkazy
Cílem výzkumu bylo ověřit vztahy mezi výkonovou orientací a sebeznevýhodňováním. Výzkumný soubor sestával z 355 studentů Sakarya University v Turecku. 201 z nich byly ženy, 154 muži a průměrný věk byl 20,2 roku. Škála 2X2 výkonové orientace a škála sebeznevýhodňování byly použity jako míry. Vztahy mezi výkonovou orientací a sebeznevýhodňováním byly zkoumány pomocí korelační analýzy a mnohonásobné regresní analýzy. Výsledky ukázaly, že sebeznevýhodňování korelovalo pozitivně s cíli vyhýbat se učení a vyhýbat se výkonovým situacím a negativně s cíli přikročit k učení a přikročit k výkonovým situacím. Podle výsledků regresní analýzy bylo sebeznevýhodňování predikováno cíli vyhýbat se učení a vyhýbat se výkonovým situacím. Dále se ukázalo, že cíle přikročit k učení a přikročit k výkonovým situacím predikovaly sebeznevýhodňování negativně. Cíle přikročit k učení/vyhýbat se učení a přikročit k výkonovým situacím/vyhýbat se výkonovým situacím vysvětlily 69 % rozptylu sebeznevýhodňování., The aim of this research was to examine the relationships between achievement goal orientations and self-handicapping. The sample of study consists of 355 university students from Sakarya University, Turkey. 201 participants were female and 154 were male, the mean age was 20.2. The 2X2 Achievement Goal Orientations Scale and the Self-handicapping Scale were used as measures. The relationships between achievement goal orientations and self-handicapping were examined using correlation analysis and multiple regression analysis. Results showed that self-handicapping correlated positively with learning-avoidance and performance-avoidance goals and negatively with learning-approach and performance-approach goals. According to regression results, self-handicapping was predicted positively by learning-avoidance and performance-avoidance goals. Further learning- approach and performance-approach goals predicted self-handicapping in a negative way. Learning-approach/avoidance and performanceapproach/ avoidance goals have explained 69% of the variance in self-handicapping. The results should not be generalized either to all university students or to other student population. Secondly, as correlational statistics were utilized, no definitive statements can be made about causality. And last, the data are self-reported., Ümran Akin., and Obsahuje seznam literatury
