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
