Influence of conidial traits and leaf structure on attachment success of aquatic hyphomycetes on leaf litter
... The weak attachment of conidia in the present experiments is likely to be related to the high turbulence prevailing in stream microcosms, which are aerated from underneath (Suberkropp 1991). However such turbulent ...
