Bc. ZUZANA JAŇÁKOVÁ: Assessing the environmental impact of trophy quality of deer. [Thesis] / Bc. Zuzana Jaňáková - Technical University in Zvolen, Faculty of Forestry, Department of Applied Zoology and Game Management - Thesis supervisor: prof. Peter Garaj, Csc., Consultant: Ing. Peter Smolko, PhD. Degree of qualification: Engineering. Zvolen LF TU, 2019My thesis deals with the evaluation of the environmental impact on trophy quality of deer in two different climates, namely the alpine and hilly (upland) region of Slovakia. The research was carried out on the territory of the High and Low Tatras and Chočské vrchy, which represented the alpine region of Slovakia and on the territory of the Kremnica Hills and Krupina Plateau, which represented the uplands of Slovakia. A total of 1102 deer trophies were collected from 52 hunting grounds between the years 2014 to 2018. We assigned an average of 10 climate factors to all the data in the areas where the deer were hunted and we tested their impact on the antler parameters. The aim of the thesis was a) To compare the size of the antlers of the deer with the high mountain and upland region of Slovakia, b) To analyze the influence of environmental factors on the size of the deer, c) To analyze the influence of the physiological characteristics of the deer on the development of deer, d) Evaluation of the importance of acquired knowledge for practice. Our results show that the greatest impact on the size of the deer's antler is the age of the deer. However, the antler was significantly larger in deer in upland area compared to deer in alpine area in 9 out of 10 compared parameters. These results were due to environmental climatic factors tested. An important finding was also the difference in trophy culmination between the monitored areas, which leads us to assume the necessity to reassess the age of the trophy culmination within the hunting areas.
