Beschreibung: A recent decline in some of the most common bird species in central Europe raises questions about the influence of birds on their habitat and vice versa. This project analysis the role of birds in forests, where populations have been more stable than among farmland species. However, forest ecosystems in central Europe underwent periods of increased stress due to unusual weather conditions in the past years resulting in reduced ecosystem productivity and local forest diebacks. To better understand the trophic cascade, this study comprises two parts. In part one, we will monitor the impact of birds on tree growth over multiple years with bird exclosure experiments and by manipulating bird populations with nesting boxes. This should reveal potential links in the food chain between the predator (birds), herbivorous insects and photosynthetic productivity of trees. In part two, we will investigate growth and health of forest birds in relation to climate change with respect to the abundance of vectors and the prevalence of diseases. Together, this research aims at a better understanding for the resilience of bird populations against future changes in forest ecosystems and under a changing climate.
Methoden: Field work and laboratory analyses will include phenological observations, dendrometer monitoring, medication experiments and NGS genetics.
