Creation of water habitats database on spoil banks in Mostecko region
Macková, Klára ; Solský, Milič (advisor) ; Gdulová, Kateřina (referee)
Post-mining sites may pose a suitable environment for many rare and endagered species, amphibians are not an exception. Population size of the model species named agile frog (Rana dalmatina) has been observed already for eight years on more than 900 water surfaces of four heaps in the Most region. The observation is based on counting nests in the spring season. Annually are the results of the counting recorded together with charasteristics of observed water surfaces. Especially noted are their expance, deepness, slope of the shores, pH, conductivity, share of aquatic vegetation etc, as well as fotodocumetations and GPS locations. In similar studies where greater number of sites is repeatedly visited, there could be a problem with the reliability of tracing exact places. For the orientation in space is usually used orthophoto map and GPS navigation with dot layer of individual sites. Errors can occur because of the large number of frequent locations, close situated locations, confusing terrain and their own error of GPS devices. There was thus to inaccuracies in the positioning of individual locations, which resulted in a poor record of each habitat. Appropriate procedure to refine the results of field research, was to create a database containing photos of the previous year and point attributes of the area and transfer to GPX format so that it can be displayed directly in the ground used by GPS devices. For this purpose was used ArcGIS geo-information system, Office software package from Microsoft and software Notepad ++. This work consists of three main parts: a literature review, methodology and attachments. As an attachment there is a detailed procedure how to uploads attributes and points photos to GPS device.

Activities and competencies of the Customs Administration of the Czech Republic within protection of endangered plants and animals
Bašta, Lukáš ; Vojar, Jiří (advisor) ; Solský, Milič (referee)
The Bachelor thesis deals with the issue of activities and competencies of the Customs
Administration of the Czech Republic as armed security force within protection of
endangered plants and animals. Bachelor thesis introduces international trade in
endangered plants and animals, legislative protection options (CITES Treaty, EU/ES law
and law of the Czech Republic) and its application in the Czech Republic, the specific
ways and means of the Customs Administration of the Czech Republic in order to detect
illegal activities, presently - an overview of discovered illegal activities by Customs
Administration of the Czech Republic for the years 2011 - 2015, assessment of trends
and developments in the context of smuggling endangered species, most smuggled
species, offenders, methods, covers, penalties, draft of prevention tools and evaluation of
the current situation.

Egg clutch deposition of the agile frog Rana dalmatina in water habitats
Kopáčová, Nikol ; Solský, Milič (advisor) ; Kopecký, Oldřich (referee)
The aim of the thesis was to further explore the habitat requirements of lean frog (Rana dalmatina). Data collection was conducted in 2007 to 2010 and 2015, a total of 27 locations Hornojiřetínské dump. Were examined factors such as the depth at which they are placed brood, the distance between the clutch, clutches distance from the shore, the location of each type clutches, or whether they are placed in the littoral or not. Furthermore, the slope of the banks surveyed sites and level of insolation. For comparison, if the total number of broods on the site may or may not affect the minimum distance between the clutch, was used Mann Whitney nonparametric test. From the results it can be assumed that the agile frog prefers for laying clutches least partially sunlit areas with plenty of littoral vegetation and gentle slope shores. Depth shallower reservoirs prefers, however, requires the presence of deeper parts of the winter. From the results of a Mann-Whitney non-parametric test in this case is not clearly confirm that the total number of clutches on the location somehow significantly affect distances closest neighboring broods, respectively, that the higher the number of males in the location dwindled defended territory of each of them, and vice versa.

Impact of habitat loss on anuran diversity in different parts of Serra do Mar, the largest remnant of Mata Atlantica, SE Brazil
Holer, Tomáš ; Hejcmanová, Pavla (advisor) ; Solský, Milič (referee)
Mata Atlantica is one of the ancient forests. It is one of the five South American biodiversity hotspots. In the recent time, over 90% percent of this rich and unique biome has been lost. This loss and huge fragmentation of the forest, resulted in a decrease and extinction of many populations of endemic species of plants and animals. Over 450 amphibian species lives in the Atlantic forest of which 60% are endemic. My research area was localized inside one of the largest Atlantic forest fragments, Serra do Mar, in the buffer area of Serra da Bocaina National Park, Brazil. Aims of these thesis were to identify the anuran diversity in the abovementioned area, estimate species habitat preferences and compare the preferred habitat map of the three model species, with their distribution maps available on their IUCN Red List account. The methodology consisted of two parts. Three line transects were placed in three different forest parts and elevations. Three night and three day surveys were done on each transect by three people. Second part was non-invasive species identification on five selected breeding ponds in the research area. During my research, 31 species of frogs were recorded and 27 of them were identified, belonging to 8 families. Hylidae (16), Hylodidae (1), Bufonidae (2), Odontophrynidae (3), Craugastoridae (1), Brachycephalidae (3), Leptodactylidae (4), Centrolenidae (1). None of those frogs are endangered according to their IUCN Red List status (1 Data Deficient, rest Least Concern). After revision and re-estimation of three model species (Aplastodiscus callipygius, Cruz and Peixoto, 1985, Adenomera marmorata, Steindachner, 1867, Haddadus binotatus, Spix, 1824) distribution maps, according to their preferred habitat, using distribution maps available on IUCN Red List, It has been found, that the endanger status of many species of frogs is most likely underestimated. Results of this thesis suggest, that large-scale research should be conducted, to get more knowledge of Mata Atlantica amphibians, to understand their behavior and ecology and through the knowledge find the way how to protect them.

Change of water habitats characteristics on technicaly unreclaimed spoil banks.
Ščudlová, Zuzana ; Solský, Milič (advisor) ; Kadlec, Tomáš (referee)
Amphibian decline in recent decades has led to increasing emphasis on monitoring amphibian population abundances. Efforts to assess the condition of each amphibian populations greatly complicate significant natural fluctuations in population size. This may occur particularly in the case of short-term studies that currently prevail. Spoil banks represent a suitable environment for a range of environmental studies. Often these places are not in direct influence of human activities, thus offering the possibility of studying natural processes. On the Hornojiřetínská spoil bank (approximately 6 km2) has been underway since 2005, abundance monitoring of agile frog (Rana dalmatina) and recording and selecting characteristics of water bodies. At the spoil bank is located about 400 aquatic habitats. 225 of them are continuously monitored the development of aquatic habitats and 134 monitored abundance of agile frog. Development of aquatic habitats is not routinely examined unlike development of terrestrial environment. Results showed that the depth of the pond is reduced, surroundings were overgrown and insolation of water level has fallen. Only littoral vegetation showed no change. Abundance of agile frog fluctuated more than 10 times during the studied period, but the data manifested no trends. Decreases slightly outnumbered increases (6 vs. 4), exhibited greater range (1.07 to 6.40 versus 1.69 to 2.40) and and occurred within a longer consecutive period (5 vs. 2 years). Furthermore, it was strong correlation between total abundance and occupied ponds. The results of this study point to the need to establish an appropriate management and the necessity of long-term studies for a correct understanding population dynamics of amphibians.
