Parasites are increasingly being recognized as potent agents of selection. Gastrointestinal parasites, however, have largely been ignored. The aim of the present thesis was to contribute to the still scarce knowledge about gastrointestinal parasites in ecological, evolutionary and behavioural studies and to critically elucidate methodological aspects of indirect parasitic assays. Fecal samples were collected from an urban, individually marked population of Eurasian Blackbirds (Turdus merula L.,1758) and were examined for eggs and oocysts of gastrointestinal parasites. Four parasitic taxa commonly occurred in the population: protozoans of the genus Isospora, nematodes of the genus Capillaria, cestodes and acanthocephalans. Isospora spp. and ...
