Description
In forested and low-relief riverine habitats, nutrient concentrations in the water column tend to be poor, the bulk of the nutrient pool existing within the substrate composing the river bottom; these nutrients are present primarily as a result of the continuous deposition of mineral- and organic-rich sediment being carried from upstream and from run-off. Water chemistry in such riverine habitats tends to be slightly-to-moderately-acidic, and generally low in concentrations of the elements that
