Ombrotrophy is the process by which the nutrient status and composition of a wetland are determined by precipitation inputs. It is an important aspect of wetland ecology and has several synonyms such as pluviotrophy, precipitation-dependent, and rain-fed. Other related terms include hydrotrophy, which refers to the process in which wetland nutrient status is controlled by water inputs, and heliophytotrophy, which refers to nutrient uptake by plants in response to sunlight. Ombrotrophy is crucial in maintaining the unique flora and fauna of wetlands, and understanding the various synonyms and related terms is important for researchers and policymakers in the field of wetland conservation and restoration. By understanding these terms, better strategies can be developed to preserve vital ecosystems and the services they provide.
