Volume, directions and trends of international trade in poison arrow frogs (Dendrobatidae)
 NOVÁKOVÁ, Markéta
Family Dendrobatidae ranks among three of the most tradable families from amphibian class in the international trade. This is one of the reasons of family downsizing. Some of Dendrobatidae species are included in the international agreement CITES appendix II. The aim of this thesis is focused on a trade of the family Dendrobatidae in the Czech Republic and other countries in 1978-2015. The CITES Trade Database was the main source for this thesis. The thesis deals with a development of time-dependent trade, individual tradable species, countries involved in the trade with the Czech Republic, the purpose of the trade and source of trade origin. The most imported species were Ameerega picta, Dendrobates auratus and Ameerega trivittata. The export became predominant compare to the import. Species Dendrobates auratus, Phyllobates vittatus and Epipedobates boulengeri were frequently exported. Species of the family Dendrobatidae were traded alive except for two records. The Czech Republic is dominated by the import of individuals from the wild than captive individuals. The opposite state was proved in case of export. The time-dependent trend is generally decreasing in the Czech Republic.

Stimulation of breeding of choose frog species in human care.
 SRB, Ondřej
The aim of this work is to investigate the effectiveness of noninvasive stimulation of reproduction for two species of tropical frogs. I choose Epipedobates anthonyi and Ranitomeya lamasi as model organisms. Stimulation was been done by playback recordings of mating calls and mirror, which was placed inside terrarium. I try to perform as most realistic imitation of competitive male as possible. Presence of male should provoke other males to greater reproductive effort. Results of this research show that males may by stimulated and activity increased. Results of this reserch may be used in captive programs of anuras with limited number of available individuals.
