Charles University, Faculty of Science Institute for Environmental Studies Doctoral study programme: Environmental Sciences Summary of the Doctoral thesis Impact of Climate Change on Czech Bird Populations Vliv klimatické změny na ptačí populace v České Republice Mgr. Tomáš Telenský Supervisor: doc. Mgr. Jiří Reif, Ph.D. Prague, 2018 Abstract Climate change is one of the most important drivers of biodiversity. If it proceeds at current pace, it will lead to homogenization and pose a serious threat to biodiversity. Birds, as one of the most researched taxonomic groups, are successfully used as indicators of biodiversity of the whole ecosystems, and thus offer an excellent opportunity to study the overall impact of climate change. We use data from repeated annual monitoring programmes in Czech Republic, Breeding Bird Monitoring Programe, based on point counts, and Constant Effort Sites mist- netting ringing programme, capture-mark-recapture schema. We found that: 1. Population growth of 6 out of 37 resident species responded negatively to seasons with lower winter temperatures. The response was stronger in species feeding on animals. 2. Long-distance (LD) migrants' breeding productivity responds negatively to higher spring temperatures and advanced spring as indicated by earlier leaf unfolding of three tree...
