Species can be regarded as ‘invasive’ when they become widespread or very abundant to the point that they adversely affect aquatic communities through direct or indirect competition with native species. When we’re swimming in a river or lake, we really don’t want to think about all those little microorganisms that surround us, do we? Ascomycetic and basidiomycetic hyphomycetes play key roles in leaf litter breakdown in rivers and creeks, while parasitic chytrids are an important food source for small invertebrates in lakes.

Microbes readily colonize aquatic plastic debris and members of these biofilm communities are speculated to include pathogenic, toxic, invasive or plastic degrading-species. The higher salt concentration, higher pH, and lower nutrients, relative to freshwater, are lethal to many microorganisms. A fresh water ecosystem is an aquatic system that contains drinkable water or water of almost no salty content. Title: … Set alert. Close your eyes and imagine the physical characteristics of a person you know well. The majority of studies on biofilms have focused on autotrophic and bacterial taxa, without considering the potential effects on biofilm grazers. Soil microorganisms are present in high numbers and have a wide range of metabolic activities and physiological properties that play a vital role in the cycling of nutrients within the soil and are essential for the removal of pollutants from soil.
