Karhánek, Jaroslav ; Hejcmanová, Pavla (advisor) ; Vladimír, Vladimír (referee)
The Atlantic Forest is pristine forest and it is also one of areas with the highest biodiversity, it is included in hotspots of the World with high percentage of endemic
fauna and flora. It is also one of the most threatened environments with more than 90 % of total area already destroyed. In the area of states Rio de Janeiro and Sao Paulo it is possible to find largest remnants of forest, which is called Serra do Mar. The main aims of the thesis were to describe the herpetofauna of the Serra da Bocaina NP. The study was conducted in the private parts in buffer zones of Serra da Bocaina National Park,
state of Sao Paulo, Brazil. In this study we were using visual encounter survey method via diurnal and nocturnal transects. The study sites were chosen in 3 different altitudes and environments. Study sites included disturbed open areas presented by pasture, wetland, agriculture land near households. The forest areas were mostly represented by secondary forest with connection to primary forests.
During the study I found a total of 87 individuals of 10 reptile species, belonging into 8 families: (1) Viperidae; (2) Dipsadidae; (3) Leiosauridae; (4) Tropiduridae; (5) Teiidae; (6) Gekkonidae; (7) Chelidae. Species diversity was given according to height
elevation and preserved forest area. The highest diversity was in mid elevation (700 m a.s.l.) and the lowest in the highest elevations of the study (1,100 m a.s.l.).

Hadi rodu Botrops: taxonomie, rozšíření, ekologie a vztah k lesním ekosystémům
Karhánek, Jaroslav
Bachelor's thesis deals with lanceheads of genus Bothrops. Main aim of this work was to find out their demands on the environment and get overview about their life. In the first part of the thesis we find description of individual species and their bionomics, threat level, ecology and encounters with people, when the snakebites can occur. In the second part the observations in the wild was realized, where several countries of Latin America, namely Nicaragua, Costa Rica, Panama and Bolivia were visited. The observation was successful only in Panama and Costa Rica. Also observations in captivity were carried out. After that we included comparison with another authors about the observation in the wild on the same localities and even the comparison of care conditions in the captivity.
