چکیده

Many of Florida’s springs and spring runs are enriched in nitrate due to broad-scale contamination of groundwater supplies. This observation fosters two primary and interrelated concerns regarding the effects of nutrients on flora and fauna in spring systems. High nitrate concentrations can affect fauna directly through toxicity. In addition, high nitrate concentrations can promote eutrophication or an increase in organic matter, which drives a diverse array of responses and feedbacks in aquatic systems that comprise a eutrophication progression scheme.

Springs as Ecosystems

Springs and spring runs represent a unique class of aquatic ecosystems typified by high water clarity and relatively constant water temperature and chemical conditions. Structurally, springs are best characterized by their basin morphometry (shape and volume), their position in the landscape, and their flora and fauna. A classic aquatic food web and biomass pyramid in spring ecosystems includes...

Experimental tree removal in tallgrass prairie: variable responses of flora and fauna along a woody cover gradient.

Woody plant encroachment is a worldwide phenomenon in grassland and savanna systems whose consequence is often the development of an alternate woodland state. Theoretically, an alternate state may be associated with changes in system state variables (e.g., species composition) or abiotic parameter shifts (e.g., nutrient availability). When state-variable changes are cumulative, such as in woody...
