The interactions between bacteria and fungi, the main actors of the soil microbiome, remain poorly studied. Here, we show that the saprotrophic and ectomycorrhizal soil fungus Morchella crassipes acts as a bacterial farmer of Pseudomonas putida, which serves as a model soil bacterium. Farming by M. crassipes consists of bacterial dispersal, bacterial rearing with fungal...

The analysis of a few moss samples collected on the walls of the castle of Neuchâtel has revealed the presence of 23 taxa of testate amoebae, among which 10 Euglyphids and 13 Arcellinids, out of an overall total of 117 observed taxa, for all taxonomic groups. As hitherto unknown species and higher taxa are continuously being discovered within the various groups of protists including testate...
