, and diversity in rivers, streams and riparian alder ecosystems of Central Europe.

Unlabelled: Waterways are ideal pathways for dispersal and potential introduction to terrestrial ecosystems. While many species from phylogenetic clades 6, 9 and 10 are predominant oomycetes in watercourses due to their adaptation to a lifestyle as saprotrophs and opportunistic pathogens of riparian plants, species from clades 2, 7 and 8 are predominantly soil- or airborne using aquatic habitats as temporal niches for spreading and invading terrestrial sites along the watercourses. In contrast to forest ecosystems, knowledge of diversity in watercourses in Central Europe is limited.

Metabolomic and Physiological Changes in Seedlings Infected with and the A1 and A2 Mating Types of .

infections are followed by histological alterations, physiological and metabolomic adjustments in the host but very few studies contemplate these changes simultaneously. seedlings were inoculated with A1 and A2 mating types of the heterothallic and with the homothallic to identify plant physiological and metabolomic changes accompanying microscope observations of the colonization process one, two and three weeks after inoculation. -infected plants died at a faster pace than those inoculated with and showed higher mortality than A1-infected plants.
