International trade in sea horses (\kur{Hippocampus spp}.)
NEDOROSTOVÁ, Anna
This work comprehensively reviews the international trade in sea horses, particularly the Hippocampus genus, from 1997 to 2012. The genus was added to the Appendices II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (thereinafter as the CITES) in 2002, came into force in 2004. Before the addition, the genus was entered into the appendix D for the non-CITES species whose import is monitored by the EU. The CITES Trade Database kept by the UNEP - WCMC Secretariat was used as the source of data about the trade. The frequency of the trade in sea horses tended to be increasing with a moderate decrease in 2009. The Hippocampus species was traded in the following forms: live, bodies, derivatives, specimens, medicine, carvings, eggs live, extracts, fingerlings, powder, skeletons, skin pieces, soup, trophies and other unspecified forms. The living specimens traded: (1) specimens taken from the wild., (2) animals bred in captivity as well as parts and derivatives, (3) Animals born in captivity (F1 or subsequent generations) that do not fulfil the definition of 'bred in captivity', as well as parts and derivatives thereof, (4) specimens of animals reared in a controlled environment, taken as eggs or juveniles from the wild, where they would otherwise have had a very low probability of surviving to adulthood, (5) confiscated or seized specimens, (6) pre- Convention specimens. The trades purposes were: (1) commercial, (2) personal, (3) scientific, (4) zoo (aquarium) breeding, (5) educational, (6) breeding in captivity, circus and other exhibitions, (7) conventional medicine, (8) law enforcement / judicial / forensic purposes. The most traded genus was unspecified (Hippocampus spp.), then the H. kuda, the H. reidi and the H. erectus as living specimens or dead bodies; also the ones from the wild and for the commercial purposes. Those came mostly from Vietnam, Thailand or Australia. They were exported mainly from Indonesia, Sri Lanka and Australia. The greatest importers were the USA, Germany and the Great Britain.

Rabbit gut associated lymphoid tissue (GALT)
NEDOROSTOVÁ, Anna
Presented bachelor project deals with rabbit?s lymphatic tissue of intestine which is the biggest lymphatic organ in a rabbit's body. In the first part of the project anatomical system of a rabbit?s intensine and it's general histological structure is described, following part deals with lymphatic tissue of intensine (Peyers patches, isolated lymphoid follicle, sacculus rotundus, cecal patch, appendix) and supplemented by macroscopic and microscopic images. Histological structure of each GALT component is identical, there are lymphatic follicles covered with special epithelium, however individual GALT components of rabbit differ in percentage of appearance of T and B lymphocyte. All GALT structures are responsible for induction of the immune response, saculus roundus and appendix are locations of formation of the primary antibody repertoire. Project created theoretical foundations for another study about lymphatic tissue of rabbit's intestine.
