- Description:
- In present paper we assess the climate change impact on mean runoff between the periods 1961-1990 (control period) and 2070-2099 (scenario period) in the Czech Republic. Hydrological balance is modelled with a conceptual hydrological model BILAN at 250 catchments of different sizes and climatic conditions. Climate change scenarios are derived using simple delta approach, i.e. observed series of precipitation, temperature and relative air humidity are perturbed in order to give the same changes between the control and scenario period as in the ensemble of 15 transient regional climate model (RCM) simulations. The parameters of the hydrological model are for each catchment estimated using observed data. These parameters are subsequently used to derive discharge series under climate change conditions for each RCM simulation. Although the differences in the absolute values of the changes in runoff are considerable, robust patterns of changes can be identified. The majority of the scenarios project an increase in winter runoff in the northern part of the Czech Republic, especially at catchments with high elevation. The scenarios also agree on a decrease in spring and summer runoff in most of the catchments. and V článku předkládáme výsledky modelování změn hydrologického režimu v důsledku změn klimatu mezi časovými obdobími 1961-1990 a 2070-2099 podle souboru patnácti regionálních klimatických modelů pro 250 povodí v České republice. Hydrologická bilance byla modelována pomocí konceptuálního hydrologického modelu BILAN. Časové řady ovlivněné změnou klimatu byly získány jednoduchou přírůstkovou metodou, tj. pozorované časové řady srážek, teplot a vlhkostí vzduchu (vstupy do modelu BILAN) byly opraveny pro každou simulaci pomocí přírůstkových faktorů tak, aby měsíční změny těchto veličin byly stejné jako podle uvažované simulace klimatického modelu. Hydrologický model je nakalibrován s využitím pozorovaných dat, identifikované parametry jsou následně využity pro simulaci hydrologické bilance pro řady ovlivněné klimatickou změnou. Základní podstata možných změn hydrologické bilance na území České republiky vyplývá z projekcí srážek a teplot pro Evropu, tj. postupné zvyšování teplot během celého roku a pokles letních, růst zimních a stagnace ročních srážek. V období od začátku podzimu do začátku léta dochází k růstu srážek, jenž je doprovázen řádově stejným růstem územního výparu způsobeným růstem teplot. V letním období dochází k poklesu srážek a v důsledku úbytku zásob vody v povodí nemůže docházet k výraznému zvyšování územního výparu. Důležitým faktorem ovlivňující změny odtoku je posun doby tání v důsledku vyšší teploty přibližně z dubna na leden-únor. Změny odtoku v období leden-květen jsou tedy dominantně určeny právě odlišnou dynamikou sněhové zásoby, změny v letním období zejména úbytkem srážek. Výsledné odhady změn odtoku jsou zatíženy značnou nejistotou, nicméně lze identifikovat robustní jevy společné pro řadu simulací. Jak ukazují výsledky, na většině modelovaných povodí je pokles odtoků v období od dubna do října společný valné většině modelů. Na druhé straně, růst odtoku v zimních měsících je značně nejistý. S tím souvisí i nejistota spojená se změnami roční bilance odtoků.

- food supply, prey delivery, nesting, Czech Republic, and Ore Mountains
- Language:
- English
- Description:
- This study investigated whether the males of the Tengmalm’s owl change their activity patterns, evaluated based on delivering prey to nestlings in respect of different food supply. During two breeding seasons 12 owl nests were continuously monitored by a camera system to obtain data on the time of male prey delivery and identification of prey items brought to nestlings. Even though the abundance of food supply differed in both years, there was no difference in the number of prey items delivered by males to their nests. Nevertheless, the species composition of food supply as well as the species composition of prey delivered by males to the nests differed between 2004 and 2006. Yet male activity patterns were the same in both years; they showed a monophasic cycle with one peak at the beginning of the night, around 22:00 and 23:00. Moreover, the males delivered prey to their chicks strictly at night time in both years and they started (the first evening arrival at the nest) and ended (the last morning arrival at the nest) their nest visiting in the same time in 2004 and 2006. The results of this study suggest that activity patterns of Tengmalm’s owl males in central Europe do not depend on varying food conditions.

- Description:
- V ČR a Polsku se v posledním období významným zahraničněpolitickým i vnitropolitickým tématem stal záměr vlády USA umístit v těchto zemích některé komponenty budovaného amerického systému obrany proti mezikontinentálním balistickým střelám, který by podle deklarovaného záměru měl chránit kontinentální území Spojených států před případným útokem prostřednictvím menšího počtu raket dlouhého doletu z tzv. „ničemných států“ (rogue states), jak je označuje americká administrativa. Vlády ČR a Polska byly v tomto směru nedávno oficiálně americkou stranou požádány diplomatickou nótou o jednání v této záležitosti. V případě Polska by se mělo jednat o odpalovací zařízení raket určených k ničení mezikontinentálních balistických střel, na českém území by pak měl být dislokován radar, jehož prostřednictvím protiraketový systém vyhledává nepřátelské střely a navádí na ně své rakety. Probíhající diskuse jak uvnitř obou oslovených středoevropských států, tak i na mezinárodním foru zřetelně ukazují, že jak konkrétní plán umístit základny antibalistické obrany v ČR a Polsku, tak zejména samotný záměr budovat byť i jen omezený systém strategické obrany tohoto druhu, představuje závažnou, značně citlivou a kontroverzní otázku s globálním dosahem. Pochopitelný a průběžně sílící zájem o věc projevují také obyvatelé obou zemí. A právě postojům české a polské veřejnosti k celému projektu, jejich aktuálnímu stavu a také možnému dalšímu vývoji se bude věnovat tento text., The text focuses on public opinion in Czech Republic and Poland relating to the plan of U.S. government to locate some parts of U.S. national missile defence in these countries. It describes and compares main shifts of developments of public attitudes in both countries to the project as well as to eventual referendum in this matter within the period up to the first half of 2007. The text shows main demographical, societal and political differences in both countries and discusses reasons and motives behind particular attitudes of Czech and Polish citizens., Jan Červenka., and Seznam literatury

- Subject:
- migration, Romani, Czech Republic, Slovakia, and social anthropology
- Language:
- Czech
- Description:
- The article on the Romani migration from Slovakia to the territory of the Czech Republic is based on the field research realized by the organization „Člověk v tísni" (People in Need) in the year 2003. Analysis of this probe has shown that the non-asylum Romani migration was in the year 2003 much stronger than the migration of asylum seekers; that in the case of non-asylum migration this was in the first place an innovation migration, while in the case of asylum seekers it was a so called survival migration. The non-asylum migration was usually a chain migration either of individuals or families and utilises family relations in the country of origin as well as in the country of final destination. The information is being handed on not only through families, but also in settlements; some of them even specialize in some kind of migration. The migration of Romani between the Czech Republic and Slovakia is bid-irectional, but more Romani migrate into the Czech Republic then to Slovakia, due to better economic situation there. Romani migration is a dynamic phenomenon and because of its character, based on close family relations of Romani residents on Czech and Slovak territory, it will for sure continue in future.

6. Believer perspectives on death and funeral practices in a non-believing country
- Creator:
- Nešporová, Olga
- Format:
- Type:
- model:internalpart and TEXT
- Subject:
- Czech Republic, death, last rites, funeral, and believers
- Language:
- Czech
- Description:
- The article describes attitudes towards death and funeral rites in contemporary Czech society. It begins by revealing the attitudes to death held by the majority of the Czech population - non-believers. The customary secular funeral ceremony, held in a crematorium, is not entirely well suited to meeting the needs of the bereaved, and this is borne out by the fact that about one-third of all cremations are held without a funeral ceremony. The author argues that the current situation is not solely the result of the economic situation of individuals but also stems from the deeply rooted attitudes and values and the approach to religion of the Czech population. The second part of the article is devoted to the attitudes towards death and the funeral rite preferences of believers, based on a survey conducted with members of three religious groups: Roman Catholics, Protestants (Church of the Czech Brethren), and Jehovah's Witnesses. Finally, the author compares the attitudes of the secular majority and believers, and also outlines the connections between conditions today and under the former communist regime regarding the general approach to death and funeral rites.

- Description:
- Two species of the genus Baruscapillaria Moravec, 1982 are known to parasitise the small intestine of the common cormorant, Phalacrocorax carbo (L.): Baruscapillaria carbonis (Dubinin et Dubinina, 1940) and B. rudolphii Moravec, Scholz et Našincová, 1994. A redescription of the former species, based on specimens collected from common cormorants shot in South Bohemia, Czech Republic, is provided. Morphological features distinguishing B. carbonis and B. rudolphii are specified. B. carbonis is characterised mainly by the well-developed membranous bursa in the male, composed of five distinct lobes (four lateral and one spur-shaped dorsal); the length of the spicule is 1.9-2.3 mm; gravid females are provided with a long vulvar appendage. Males of B. rudolphii have reduced, bi-lobed membranous bursa and the spicule is 0.9-1.3 mm long; the vulvar appendage is absent in gravid females. This is the first record of B. carbonis in the Czech Republic.

- Language:

- Description:
- A complete list of all alien taxa ever recorded in the flora of the Czech Republic is presented as an update of the original checklist published in 2002. New data accumulated in the last decade are incorporated and the listing and status of some taxa are reassessed based on improved knowledge. Alien flora of the Czech Republic consists of 1454 taxa listed with information on their taxonomic position, life history, geographic origin (or mode of origin, distinguishing anecophyte and hybrid), invasive status (casual; naturalized but not invasive; invasive), residence time status (archaeophyte vs neophyte), mode of introduction into the country (accidental, deliberate), and date of the first record. Additional information on species performance that was not part of the previous catalogue, i.e. on the width of species’ habitat niches, their dominance in invaded communities, and impact, is provided. The Czech alien flora consists of 350 (24.1%) archaeophytes and 1104 (75.9%) neophytes. The increase in the total number of taxa compared to the previous catalogue (1378) is due to addition of 151 taxa and removal of 75 (39 archaeophytes and 36 neophytes), important part of the latter being the reclassification of 41 taxa as native, mostly based on archaeobotanical evidence. The additions represent taxa newly recorded since 2002 and reported in the national literature; taxa resulting from investigation of sources omitted while preparing the previous catalogue; redetermination of previously reported taxa; reassessment of some taxa traditionally considered native for which the evidence suggests the opposite; and inclusion of intraspecific taxa previously not recognized in the flora. There are 44 taxa on the list that are reported in the present study for the first time as aliens introduced to the Czech Republic or escaped from cultivation: Abies concolor, A. grandis, A. nordmanniana, Avena sterilis subsp. ludoviciana, A. ×vilis, Berberis julianae, B. thunbergii, Bidens ferulifolius, Buddleja alternifolia, Buglossoides incrassata subsp. splitgerberi, Buxus sempervirens, Corispermum declinatum, Cotoneaster dielsianus, C. divaricatus, Euphorbia myrsinites, Gleditsia triacanthos, Helleborus orientalis, Hieracium heldreichii, Koelreuteria paniculata, Lonicera periclymenum, Lotus ornithopodioides, Malus baccata, M. pumila, Miscanthus sacchariflorus, Morus alba, Muscari armeniacum, Paeonia lactiflora, Pennisetum alopecuroides, Pinguicula crystallina subsp. hirtiflora, P. grandiflora subsp. rosea, Podophyllum hexandrum, Pyracantha coccinea, Rhodotypos scandens, Rumex patientia × R. tianschanicus ‘Uteuša’, Salix cordata, Sarracenia purpurea, Sasa palmata ‘Nebulosa’, Scolymus maculatus, Spiraea japonica, Tagetes tenuifolia, Thuja occidentalis, Trifolium badium, Vaccinium corymbosum and Viburnum rhytidophyllum. All added and deleted taxa are commented on. Of the total number of taxa, 985 are classified as casuals, 408 as naturalized but not invasive, and 61 as invasive. The reduction in the number of invasive taxa compared to the previous catalogue is due to a more conservative approach adopted here; only taxa that currently spread are considered invasive. Casual taxa are strongly overrepresented among neophytes compared to archaeophytes (76.7% vs 39.4%), while naturalized but non-invasive taxa follow the reversed pattern (18.8% vs 57.4). However, these two groups do not significantly differ in the proportion of invasive taxa. Of introduced neophytes, 250 taxa (22.6%) are considered vanished, i.e. no longer present in the flora, while 23.3% became naturalized, and 4.5% invasive. In addition to the traditional classification based on introduction–naturalization–invasion continuum, taxa were classified into 18 population groups based on their long-term trends in metapopulation dynamics in the country, current state of their populations, and link to the propagule pressure from cultivation. Mapping these population groups onto the unified framework for biological invasions introduced by Blackburn et al. in 2011 made it possible to quantify invasion failures, and boom-and-busts, in the Czech alien flora. Depending on inclusion criteria (whether or not extinct/vanished taxa and hybrids are considered), alien taxa ever recorded in the Czech Republic contribute 29.7–33.1% to the total country’s plant diversity; taking into account only naturalized taxa, a permanent element of the country’s flora, the figure is 14.4–17.5%. Analysis of the dates of the first record, known for 771 neophytes, indicates that alien taxa in the flora have been increasing at a steady pace without any distinct deceleration trend; by extrapolating this data to all 1104 neophytes recorded it is predicted that the projected number would reach 1264 in 2050. Deliberate introduction was involved in 747 cases (51.4%), the remaining 48.6% of taxa are assumed to have arrived by unintentional pathways. Archaeophytes are more abundant in landscapes, occupy on average a wider range of habitat types than neophytes, but reach a lower cover in plant communities. The alien flora is further analysed with respect to representation of genera and families, origin and life history. and Nevejdou se dvě poslední jména autorů

10. České kulturně-historické regiony ve vědomí svých obyvatel
- Creator:
- Siwek, Tadeusz and Bogdová, Kamila
- Format:
- Type:
- model:internalpart and TEXT
- Subject:
- cultural-historical region, regional identity, mental maps, and Czech Republic
- Language:
- Czech
- Description:
- The Czech Republic is comprised of different regions at the sub-national level. These are the historical lands of Bohemia, Moravia, and (part of) Silesia, small ethnographic regions, and administrative units. Their objective hierarchy derives from their former historical role, from their administrative function today, and their regional importance. In this article the authors attempt to describe the subjective hierarchy of these regions in the minds of their inhabitants, drawing on a survey of 1203 respondents from throughout the Czech Republic conducted in 2003 by the Centre for Public Opinion Research. The historical lands of Bohemia and Moravia are two regions whose existence Czechs recognise without question, while Silesia is in a weaker position and garners only two-thirds of the level of recognition accorded the other two historical lands. The cultural or ethnographic regions and the administrative units are on an approximately equal level, which is distinctively lower than that of the three Czech historical lands. More of these small regions are located in Moravia than in Bohemia or Silesia. The best known Czech regions are: Wallachia, Moravian Slovakia, Hana (all of which are in Moravia) and the Region of Khods (Bohemia). The best known region that is neither ethnographical nor one of the administrative units is the former industrial region of Ostrava.
