| Summary: | Trees and shrubs often act as ecosystem engineers, with impacts on light conditions, vegetation structure, and co-occurring species. There is a large body of evidence that invasive alien woody species exert a wide range of impacts on ecosystems they invade, but very little is known about whether native woody species can have similar impacts. To gain insight into these issues, this bilateral project will compare the impacts of alien vs. native trees and shrubs on vegetation, soil properties, and the activity of soil biota at different times of vegetation season. The fieldwork will be carried out in the Czech Republic and Poland and will involve a number of shrubs and trees to allow for generalization across species. By comparing alien and native species with control plots, we will estimate their net impact. We will combine vegetation sampling with soil (physical, chemical and biological properties) indicators. We will compare pairs of similar species and then order them according to the impact. We will also assess the potential of next-generation sequencing for measuring impact. Bilateral project with PL |
