Research

Dr. Von Holle is interested in the landscape patterns and community mechanisms that influence the addition of species into ecosystems. Her research interests span four related themes: 1) the investigation of ecosystem and anthropogenic factors that influence invasion by nonnative species, 2) understanding changes in ecosystem function as a result of ecological restoration, 3) the characterization of the impact and type of species to invade natural areas, and 4) economic impacts and policy implications of nonnative species invasions. Her research approaches have included landscape-scale quantification of environmental and land-use history parameters paired with experimental manipulations of natural communities, restoration experiments, greenhouse experiments, meta-analyses of global patterns of invasion, literature reviews, and spatial and null models. She employs multi-scale techniques, where she determines landscape-level influences on nonnative species demography and further investigates these influential factors with patch-scale community manipulations and analyses. Her interest in landscape preservation is served by utilizing a variety of methods to answer pressing questions relating to the addition and loss of species in ecosystems.
