dc.description 1. Invasive forest pathogens of the genus Phytophthora are threatening ecosystems globally. Phytophthora species are mainly introduced by humans importing infected nursery stock. However, due to the presence of environmental filters, not all introduced Phytophthoras manage to establish and spread. Some Phytophthoras’ ability to overcome these filters may be linked to functional traits. In Northern Europe, the increasing number of reports calls for a better understanding of the invasion process to prevent future outbreaks. 2. We hypothesized that the incidence of invasive Phytophthoras in urban locations would be higher than in remote forests, that there would be a decrease of species richness along the invasion process because of environmental filtering, and that there would be a functional shift among Phytophthora communities between stages of invasion. We compared the species composition of 96 plots from 16 rivers running through areas that constitute a gradient of human influence. We also compared the species composition and functional diversity of Phytophthora communities in 8 nurseries and 14 forests, including anthropogenic and natural forests. Phytophthoras were isolated from river water, soil, and/or plant tissue. Cultures were identified based on the Internal Transcribed Spacer (ITS) region. 3. Three Phytophthoras were detected in all environments (P. cactorum, P. plurivora, and P. cambivora). Their incidence was higher in urban locations than in remote forests, supporting the role of human activity as a driver of invasion. Most of the Phytophthoras detected in forests were detected in nurseries. The Phytophthora community in nurseries was richer and more diverse than in forests, pointing to environmental filtering affecting the establishment. Phytophthora communities in nurseries and forests differed in their functional divergence. Traits associated with establishment were the ability to form asexual survival structures and lower cardinal temperatures for growth. 4. Synthesis and applications. Our findings support the view that human activities act as drivers of Phytophthora invasions, and suggest that Phytophthoras that are able to form asexual structures are more likely to establish in northern Europe. The results increase the capacity to predict the establishment of Phytophthora species in Sweden and expand our understanding of the invasion process of forest pathogens.15-Nov-2017

Description The excel file contains two sheets. In the sheet one, we provide the results of the baiting in the rivers. In the first four columns, we provide information about the sampling plot. In the next columns, we present the count data (number of isolates) for each of the species. In the second sheet, we provide the information of the survey in the nurseries, anthropogenic forests and natural forests. The first two columns correspond to the site and the type of environment. In the rest of the columns, we present the count data (number of individuals) for each of the species. In this second sheet of the file, we present the individuals and not the isolates because for the survey in nurseries and forests, all diversity calculations are based on individuals.
