The aim of my thesis was to evaluate two methods of monitoring of the American mink and polecat, monitoring with live traps and by floating rafts. While the first method is commonly used in our country, where the second method is the pilot project here, but it has been used in the UK successfully. Observation was from August to November in 2008 and from April to November in 2009. Observation took place in the area near PP Černíč near Dačice, where were chosen 4 different habitats. All detected tracks of Mustelids found on rafts were from the American mink. It corresponds with captures, where were captured also only minks and no polecat. Occupation of rafts was higher in 2008 than in 2009 because of the eradication of mink in November 2008. In both years the highest occupancy rate in rafts was in September and the lowest in October. There were differences between habitats and number of captured minks and tracks. In compare between rafts and traps, rafts were more successful method.

Beginning May 1st 2004 the Czech republic became a part of the EU that brought large opportunities to the Czech republic citizens for job seeking abroad. Personally, I have a three-year job experience in Great Britain and would recommend this to anyone who is not afraid to travel outside their country and to get to know different cultures of other EU countries. The aim of this theses {\clqq}Job market in the EU countries and employment opportunities for the Czech republic citizens`` is to find out what destination countries are the most common choice and if CZ citizens are interested in searching for a job in EU at all. I put together a simple questionnaire and handed it out to 50 students and 50 employed CZ citizens. The Effort was to find out the development of employment in EU. The questionnaire inquiries find out the positions of students and employees in foreign countries.
