The bird communities at anthropogenic sites in the farmland: which factors affect the species abundance and diversity?
ŠTANGELOVÁ, Klára
Since the second half of the twentieth century, farmland birds have been among the most declining bird communities, and presently their numbers continue to drop. Factors behind the decline of the abundance and diversity are the loss of landscape heterogeneity, excessive use of pesticides, modernisation of rural areas and countryside, and urbanisation or brownfields restoration. In this thesis, I focus on the description of the abovementioned factors. The thesis also aims to analyse the data acquired from the databases of the Nature Conservation Agency of the Czech Republic, as well as to detect numbers and species diversity at eight selected anthropogenic sites. Amongst these sites are both active and abandoned farmsteads, manure heaps, industrial areas, train stations, quarries, grasslands, and woodlots.
