Full Answer

How are aquatic ecosystems classified by ecologists?

There are three basic types of freshwater ecosystems:

How are the major zones in river ecosystems determined?

See also: River ecosystem. The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow-moving water of pools.

What are the abiotic factors that affect aquatic ecosystems?

Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow. It is often difficult to determine the relative importance of these factors without rather large experiments. There may be complicated feedback loops. For example, sediment may determine the presence of aquatic plants, but aquatic plants may also trap sediment, and add to the sediment through peat.

What are autotrophic organisms?

Autotrophic organisms are producers that generate organic compounds from inorganic material. Algae use solar energy to generate biomass from carbon dioxide and are possibly the most important autotrophic organisms in aquatic environments. The more shallow the water, the greater the biomass contribution from rooted and floating vascular plants. These two sources combine to produce the extraordinary production of estuaries and wetlands, as this autotrophic biomass is converted into fish, birds, amphibians and other aquatic species.

What are the ecosystems of aquatic life?

Aquatic ecosystems support a wide range of organisms, including microorganisms, invertebrates, insects, plants, and fish. Some hydrologists work in understanding the trophic systems within aquatic ecosystems and their health as a function of environmental conditions such as water temperature and turbidity. Aquatic biodiversity is a major concern in water conservation and restoration projects, as well as water resource management. Concern regarding the biological health of wetlands, rivers, and lakes has led to the idea of ‘ecosystem services’ as a means to quantify or assess the value provided to society by different natural environments, including aquatic environments. While this lens seems biased to the larger species that are of commercial value (i.e. fish), it is understood that healthy waters require the full spectrum of organisms as part of an aquatic ecosystem. The section on aquatic biology provides considerable detail on many of these species.

How do aquatic ecosystems help humans?

Aquatic ecosystems worldwide provide important resources for human populations. Estuarine and marine habitats provide many essential ecosystem services, including climate regulation, yet currently these systems are impacted over large areas through over-exploitation and degradation. Moreover, aquatic ecosystems represent an integrative picture of environmental impacts and management practices operating in the terrestrial hinterland. Scientists have as yet not been able to develop predictive whole ecosystem simulation models, and no single method of food web analysis has been subjected to extensive validation of its predictive capabilities. This chapter describes factors that act at the level of individuals and populations, but whose influence on the food web dynamics and ecosystem functioning is as yet poorly understood. It is suggested that the neglect of these factors, among others to be discovered and explored, contributes to the uncertainty of predictive ecosystem simulation models. The use of larger-scale network approaches and the need for quantitative descriptors of food webs is emphasized, and concluded with challenges in application of food web theory to management issues in aquatic systems.

How does urbanization affect aquatic ecosystems?

Urban aquatic ecosystems provide a wide range of ecosystem services, which are the goods and services produced by ecosystems that are beneficial to humans (Table 5 ). The impacts of urbanization described in the previous sections have reduced the capacity of aquatic ecosystems to provide these services. For example, increasing impervious cover reduces groundwater recharge, storage of floodwaters and sediments, capacity for nutrient and contaminant removal, all of which impact water quality and aquatic biodiversity. As city dwellers recognize the value of ecosystem services, there is growing interest in preservation (e.g., greenways) and rehabilitation of urban aquatic ecosystems (e.g., riparian planting, daylighting streams previously encased in culverts). Ecologically sensitive development of urban waterfronts and trails along waterways can provide both economic and ecological benefits to city dwellers. As the proportion of the human population living in urban areas continues to increase, aquatic ecosystems in the city offer places for spiritual renewal as well as valuable opportunities to enjoy and learn about the natural world.
