Interspecies interactions in aquatic hyphomycetes

Aquatic hyphomycetes (Moniliales) constitute a predominant mycoflora on submerged decaying allochthonous plant debris, both in lentic and lotic systems. These fungi exhibit a remarkable seasonality, and to explain this, a couple of models have been put forward, which tend to establish a strong correlation of their seasonal occurrence with temperature and pH of the aquatic systems. This study provides additional evidence that both vegetative and reproductive success of aquatic hyphomycetes is significantly affected by the interspecies interactions within this group.
