Water Moulds Form Part of Terrestrial Ecosystem in a Transition from Aquatic to Soil Habitat

Watermoulds fundamentally form the indispensible part of the aquatic fungal flora of ponds and rivers and the soils of nearby areas. They constitute one the significant producers of organic matter and are important constituent of the aquatic food-web. These members require aquatic environment for their propagule germination, vegetative growth, sporulation, and the dissemination of propagules and prefer soils with high moisture content. Seasonal propagules movement have indicated that the evanescent propagules (zoospores) which are responsible for isolations move towards the permanent water-bodies during monsoon via slopes. Studies have shown that the nonsaprolegniaceous forms have a better adaptability to the terrestrial habitats than the saprolegniaceous forms.
