Abstract: Invasive Arten beeinflussen Ökosystemprozesse, Biodiversität, Ökosystemleistungen und das Wohlbefinden des Menschen. Studien haben die Bedeutung funktioneller Merkmale für den Invasionserfolg hervorgehoben. Meine Arbeit besteht aus drei Hauptthemen, in denen ich folgendes untersuche: - Ökosystemleistungen und negative Auswirkungen invasiver Pflanzenarten und wie funktionelle Merkmale über Ökosystemleistungen und negative Auswirkungen mit verschiedenen sozioökonomischen und ökologischen Sektoren verknüpft sind. - Der Zusammenhang zwischen funktionellen Merkmalen und Umweltfaktoren und wie sie sich zwischen einheimischen und gebietsfremden Pflanzenarten unterscheiden. - Lokale Veränderungen der funktionellen Vielfalt einheimischer und gebietsfremder Pflanzenarten (Archaeophyten, nicht-invasive und invasive Neophyten) über drei Jahrhunderte der Urbanisierung.
Invasive species impact ecosystem processes, biodiversity, ecosystem services, and human well-being. Alien species may differ in their traits from natives, and have traits which can be advantageous. In my thesis, I focus on the role of functional traits in the invasion process. Firstly, I offered a conceptual framework, linking functional traits of invasive species with ecosystem services and disservices. Further, I discussed the trait-environment relationships of native and alien species. I found that the relationship between traits and environment was not prominent in native; however, invasive neophytes have the largest number of relationships, followed by non-invasive neophytes and finally archaeophytes. Finally, I observed how the functional diversity (FD) changed over 320 years. I found that overall FD did not change significantly over time. FD increased in invasive and noninvasive compared to native species, and I observed an increase in most of the invasive species’ traits.
