Hodnocení fragmentace krajiny Západních Karpat ve vztahu k výskytu velkých šelem / Assessment of landscape fragmentation of Western Carpathians in relation to occurrence of large carnivores

Vlková, Kristýna January 2017 (has links)
This thesis deals with the landscape fragmentation in relation to the spatial and migration requirements of large carnivores in Western Carpathians region. Based on the data of the model species (Lynx Lynx) occurrence and selected environmental factors, the habitat suitability for Lynx Lynx is discussed using the Maxent habitat model. Employing the Effective Mesh Size method, the current landscape fragmentation caused by the transport infrastructure and urban development is studied in detail in terms of the fragmentation geometry. In addition to the analysis of measure of the current fragmentation, this thesis also includes a prediction of development of the landscape fragmentation in relation to the planned large transport constructions up to the year 2030. Comparing the habitat suitability model with the measure of current landscape fragmentation, the areas with the greatest potential of the Lynx Lynx permanent occurrence as well as the problematic areas in view of the dispersion and individuals migration are determined. Comparing the habitat suitability model with the prognosis of development of the landscape fragmentation, the impact of the planned road constructions on the suitable habitat is assessed.

Exhumace střednokorových hornin mechanismem křehce-duktilního odstřešení na příkladu veporského krystalinika v Západních Karpatech / Exhumation of mid-crustal rocks by a brittle-ductile unroofing mechanism, an example from the Veporic crystalline complex in the West Carpathians

Bukovská, Zita January 2010 (has links)
Study of the structural and metamorphic record of the eastern part of contact zone within Vepor and Gemer units in Central West Carpathians has interpreted the burial and exhumation in the evolution of alpine orogeny. The studied area is built by granitoid rocks of Vepor basement and metapelites of cover sequences both Vepor and Gemer units. Three structural fabrics have been identified in the area, which are correlated with so far described deformation stages. Higher metamorphosed rocks with presence of two generation garnets were found out within lower metamorphosed metapelites of cover sequences. From the garnet - biotite thermometry the metamorphic conditions for the rims were established to 550-580řC. Whereas muscovite and in some case chlorite, are the only metamorphic phases in neighbouring cover rocks. Three generations of white micas are documented within structural fabrics. The oldest muscovites, magmatic in origin (Ms1), younger phengites (Phg) present in fabrics S1 and youngest muscovites (Ms2) present in fabric S2. The study of quartz microstructures distinguished aggregates and from aggregates coming band microstructures. These are mostly found in deformed granitoids, sometimes also in cover quartzites and can have sigma-shape geometry. The aggregate microstructure, representing S1...

Breaking down barriers: Euroregional cooporation of the Czech Republic

Benko, Karen January 2014 (has links)
Cooperation between people of different nations has existed throughout Europe for centuries on an informal basis as borders have shifted and power has found its way into different hands. During the European integration process of the 1950s, this cooperation was formalized with the creation of the Euroregions, or cross-border regions. These regions were formed to promote common interests and cooperation to counteract barriers and benefit the people residing in the area. The Czech Republic is currently a member of 13 different Euroregions either exclusively or with multiple neighboring countries: Poland (7), Austria (3), Germany (4), and Slovakia (2). Of these 13 regions, four - Silva Nortica (Czech-Austrian, 2002), Bílé-Biele Karpaty (Czech-Slovak, 2000), Silesia (Czech-Polish, 1998), and Egrensis (Czech-German, 1993) - have been chosen to further evaluate how the creation of Euroregions has facilitated regional development. This thesis aims to analyze the level of regional development in the programming periods before and after the accession of the Czech Republic to the European Union in these four Euroregions through the application of the theory of learning regions. Then, by applying the three criteria of theory of learning regions to the four chosen Euroregions, it will determine how the...

Belemniti spodní křídy lokality Štramberk: taxonomie, stratigrafie, paleoekologie, paleobiogeografie / Lower Cretaceous belemnites of the locality Štramberk: taxonomy, stratigraphy, palaeoecology, palaeobiogeography

Vaňková, Lucie January 2015 (has links)
The study (MS, diploma thesis) is based on more than 1200 belemnite rostra set from the Lower Cretaceous sediments of locality Štramberk (N Moravia). Investigated rostra come from the collection of Dr. V. Houša, who collected them during the seventies to eighties of the last century, during intensive excavation of the Lower Cretaceous tectonic block named Š-12 "pocket". Belemnite rostra were determined at species and generic levels including 7 species and 18 genera. The majority of belemnite assemblage comes from the Lower Valanginian strata, however, also the Tithonian, Berriasian and Hauterivian taxa are present, what clearly documents the redeposition. The presence of mesohibilitids, known from the Barremian and younger deposits, still remains enigmatic. For better understanding of the redeposition proces, the alveolar infill formed by several generations of sediments, are investigated. Study of these sediments outlines the sedimentary development of the Baška elevation inside the Outer Carpathian system. Preliminary stable isotope data δ18 O and δ13 C received from belemnite rostra show different belemnite life-style during the ontogeny - i.e. juvenile bottom life style and adults inhabiting shallow/warmer waters. Negative values of δ18 O should be correlated with the "Valanginian extinction...

Liší se klíčivost vybraných druhů vstavačovitých rostlin\nl{} na přirozených a obnovených loukách? / Does it differ the germinability of the chosen orchids on the natural and renewed meadows?

SUCHÁČEK, Pavel January 2015 (has links)
The survey presented in this thesis focused on germination of six orchid species in the Protected landscape area White Carpathians; specifically Platanthera bifolia, Neottia ovata, Anacamptis pyramidalis, Gymnadenia conopsea subsp. conopsea, Traunsteinera globosa, Orchis militaris on restored medows of various age. As the control, two National Protected Areas (Zahrady pod Hájem and Čertoryje) were used. The initial stage of germination was detected on both restored and control meadows. The advanced stage of germination (protocorm) was recorded in three species (GC, NO, PB) on restored meadows, and in all species on kontrol meadows. The other aim of the thesis was to determine via molecular methods, which species of mycorrhizal fungi are associated with the model orchid species.

Ekologie rysa ostrovida (Lynx lynx) a vlka obecného (Canis lupus) v oblasti Západních Karpat a jejich význam v lesním ekosystému

Kutal, Miroslav January 2014 (has links)
The abundance and population density of the Eurasian lynx (Lynx lynx) were studied during two winters 2011/2012 and 2012/2013 in the in Beskydy and Kysuce protected landscape areas in the West Carpathians in the Czech-Slovak borderline. A combination of camera trapping, photographic capture-mark-recapture (CMR) and simultaneously conducted snow tracking revealed 11 independent lynx in both seasons in the total area of 1500 km2 and overall population density of 0.7 lynx/100 km2. High population turnover of 54.5% was documented between the two winters, indicating a strong anthropogenic pressure at the edge of the West Carpathian population. The main prey of Eurasian lynx in winter was a roe deer (81%) and red deer (16%). The occurrence of wolves (Canis lupus) was considered to be sporadic and probably limited to only a few individuals. The nearest reproductive packs were documented at a distance of 10--50 km from the Czech border in the Slovak Carpathians.

Hodnocení ekologických limitů a zdravotního stavu buku lesního (Fagus sylvatica) v oblasti vnějších západních Karpat

Mikulenčák, Josef January 2017 (has links)
European beech is an important and irreplaceable economic tree species in the forests of the Czech Republic. This thesis was created in thearea of Outer Western Carpathians, and it focuses on evaluation of ecological limits and the health condition of beech on network-based research plots from 2th vegetation tier (280 m) after 8th vegetation tier on the Lysá Mountain (1323 m). In each research area, basic dendrometry characteristics were measured and evaluated biotic and abiotic damage was evaluated. The results indicate that optimal growth conditions for beech are in the 4th vegetation tier. In other vegetation tiers, beech is more limited by abiotic factors than by biotic factors. In the 2th and 3th vegetation tier, the growth of beech is limited by frequent occurrence of drought. In contrast in higher vegetation tiers (6th, 7th, and 8th), frost, glaze and shorter growing period associated with lower average temperatures have the highest impact on the growth of beech. High vitality, wide ecological valence, a limited amount of biotic factors which damage beech and the ability to change the growth symptoms in individual vegetation tiers made beech into one of the main edificators of vegetation tires.
