Decline of czech populations of the most threatened wetland birds: comparing evidence for drivers in the Czech and foreign literature
Ráslová, Pavlína ; Reif, Jiří (advisor) ; Kindlmann, Pavel (referee)
The theme of this Bachelor's Thesis is to find relevant sources about specific factors, which cause changes in the density of the 4 most threatened species of wetland birds living in the Czech Republic. Those are the species, whose density fell most within the last decades. Specifically, this work looks at lapwing (Vanellus vanellus), snipe (Gallinago gallinago), godwit (Limosa limosa) and curlew (Numenius arquata). The target of this thesis is to differenciate relevant sources against irrelevant ones, which are often present as vague information spread outside of relevant literature and lacking a scientific fundament. Accurate indentification of the reasons of decreasing densities of these species is a neccesary prerequisite for any effort for their preservation. That is why it was essential to draw specific factors, which are the source of decline of these species, mainly from studies based on research in other european countries. Keywords: Wetland, intensification of agriculture, breeding habitat, management, population decline, Vanellus vanellus, Gallinago gallinago, Limosa limosa, Numenius arquata

Vyhodnocení welfare expozice v zoo Hluboká
MEJDA, Tomáš
Welfare or well-being of animals is currently one of most discussed topic. It has a condition called. "Rule of the five freedoms," according to Webster (1999), which is already several decades regulate to perfection. To breeder with his animals to reach well-being, should fulfill these few rules. Unfortunately, there is usually not enough attention to animal welfare. Because of these facts has been treated this thesis, aimed to evaluate the predetermined requirements for welfare selected exposure of waders in in Hluboká zoo. Furthermore, to evaluate which of the monitored types of exposure most convenient and suggest necessary improvements. Exposure assessment inhabits in total twenty kinds of birds, from which it was, after careful selection, selected eleven kinds for the evaluation. From obtained and elaborated results suggest that exposure of waders, despite the minor problems in terms of matching and welfare the glossy ibis (Plegadis falcinellus) preferably benefits.
