Description: Das Projekt "Forest management and habitat structure - influences on the network of song birds, vectors and blood parasites" wird vom Umweltbundesamt gefördert und von Universität Freiburg, Forstzoologisches Institut, Professur für Wildtierökologie und Wildtiermanagement durchgeführt. Forest structure is altered by humans for long times (Bramanti et al. 2009). The long lasting modification of forests pursuant to human demands modified the living conditions for birds as well as for many other animals. This included changes in resource availability (e.g., food, foraging, nesting sites) and changes of interspecific interactions, e.g., parasitism and predation (Knoke et al. 2009; Ellis et al. 2012). Also species compositions and the survivability of populations and even species are affected. The loss of foraging sites and suitable places for reproduction, the limitation of mobility due to fragmented habitats and the disturbances by humans itself may lead to more stressed individuals and less optimal living conditions. In certain cases species are not able to deal with the modified requirements and their populations will shrink and even vanish. Depending on the intensity of management and the remaining forest structure, biodiversity is more or less endangered. Especially in systems of two or more strongly connected taxa changing conditions that affect at least one part may subsequently affect the other, too. One system of interspecific communities that recently attracted the attention of biologists includes birds, blood parasites (haemosporidians) and their transmitting vectors. For instance, avian malaria (Plasmodium relictum) represents the reason for extreme declines in the avifauna of Hawaii since the introduction of respective vectors (e.g. Culicidae) during the 20th century (van Riper et al. 1986, Woodworth et al. 2005). With the current knowledge of this topic we are not able to predict if such incidences could also occur in Germany. All in all, different management strategies and intensity of forest management may influence the network of birds, vectors and blood parasites and change biodiversity. To elucidate this ecological complex, and to understand the interactions of the triad of songbirds as vertebrate hosts, dipteran vectors and haemosporidians within changing local conditions, I intend to collect data on the three taxa in differently managed forest areas, the given forest structure and the climatic conditions. I will try to explain the role of abiotic factors on infection dynamics, in detail the role of forest management intensity. Data acquisition takes place at three spatially divided locations: inside the Biodiversity Exploratory Schwäbische Alb, at the Mooswald in Freiburg, and inside the Schwarzwald.
