The effect of climate change and land use change on the long-term population trends of birds in the Czech Republic
Koschová, Michaela ; Reif, Jiří (advisor) ; Voříšek, Petr (referee)
There are number of future projections of species' geographic ranges developed under conditions of ongoing climate change. However, only a few studies have assessed what are the characteristics of species explaining interspecific variability in the projected range shifts. Examination of such relationships is important for development of effective conservation strategies mitigating the effects of climatic changes. For this purpose, I calculated the predicted shifts of European ranges in Czech birds based on maps in A Climatic Atlas of European Breeding Birds and explored relationships between these predicted shifts and several ecological traits. We found significant effects of the type of European distribution and habitat requirements. Concerning the type of European distribution, the largest shift is predicted in the central species and the northern species compared to widespread and southern species. According to the habitat type, the largest shift showed forest birds in contrast to the urban species which will shift slightly. The former pattern is probably attributable to spatial constrains different among these specific groups (central species are less limited compared to widespread species). The latter pattern could be explained by higher sensitivity of forest species to climatic changes...

The impact of climate and land-use changes on birds
Koschová, Michaela
Climate changes associated with increasing global temperature affect bird species. As a result, breeding ranges of European bird species will probably shift in future. Although it is unclear whether these shifts will come true, we can already see patterns recent bird population trends consistent with the impact of the changing climate. The results of our first analysis based on large-scale monitoring data showed that species with more northern latitudinal distributions had more negative population trends in the Czech Republic. Climatically induced shifts of species' geographic ranges can also provide important information about the potential future assembly of ecological communities. For this purpose we calculated the potential shifts of breeding ranges of European birds and explored their relationships with ecological variables to detect which ecological groups of birds will be most likely forced to move their ranges. Breeding habitat type showed the strongest relationship with the potential range shifts. The magnitude of the shifts can be considered as a measure of the climate change pressure on species. From this perspective, it is interesting to ask how these shifts relate to current species' population trends. Therefore we related the potential shifts to the long-term population trends of...
