Final Report Abstract
We provide here a baseline of the diversity and distribution of soil oomycetes, classified by lifestyles (biotrophy, hemibiotrophy and saprotrophy), and of cercozoan/endomyxan, classified by trophic guilds (bacterivory, eukaryvory, omnivory and plant parasites). In Oomycetes, we found a majority of hemibiotrophic plant pathogens, which are parasites spending part of their life cycle as saprotrophs after the death of the host. For Cercozoa/Endomyxa, our study surprisingly showed that endomyxan plant parasites of worldwide importance (Phytomyxea) were absent from forests, but were responsive to anthropogenic land-use intensification in grasslands. We found drastic differences in protistan community composition between grassland and forest. In forest, relative abundances of cercozoan bacterivores/eukaryvores and of oomycete obligate biotrophs/hemibiotrophs differed between regions and showed opposite responses to edaphic conditions and human-induced management intensification, suggesting different ecological requirements for these two functional guilds.
