Ecology of Freshwater and Estuarine Wetlands
It is not possible to develop a common framework for the study, management or policy of such a large and divergent assemblage of habitats with water being a single shared feature. In this paper, I argue that wetlands are distinct from deep open water systems such as rivers, lakes and reservoirs. The restriction of macrophytes except the free floating plants like salvinia and water hyacinth to shallow water habitats helps distinguish between wetlands and deep water systems. Following an ecosystem service approach, I discuss that wetlands are generally characterized by the occurrence of macrophytes, which critically contribute to their provisioning, regulating, supporting and cultural ecosystem services that differ significantly from those of the microphyte phytoplankton -dominated deep water habitats. I argue that wetlands do lie adjacent to deep and open water systems including large rivers , which interact with them regularly and influence their biodiversity, hydrology, water quality and functioning, depending upon their relative areal extent and characteristics of the macrophyte community, but that only the littoral zones between the mean highest and lowest water levels and stream banks and the floodplains beyond them in the case of rivers should be treated as wetlands. Shallow lakes devoid of macrophytes because of eutrophication are degraded wetlands that need to be restored. This is a preview of subscription content, access via your institution.
Wetlands are among the worlds' most important, but also most threatened, environmental resources. Wetland losses have been in progress particularly from the industrial revolution onwards, because wetland functions could not successfully compete for space with other land uses. Wetlands became recently foci of conservation efforts because of the increased awareness of their importance in water management and wildlife conservation, and because of the diversity of their habitats. The major Dutch wetland types are: coastal ecosystems, large riverine systems, base-rich freshwater systems, and nutrient-poor freshwater systems. Most threats to the Dutch wetlands are of man-made origin.
The Ecology and Management of Wetlands
This second edition of this important and authoritative survey provides students and researchers with up-to-date and accessible information about the ecology of freshwater and estuarine wetlands. Prominent scholars help students understand both general concepts of different wetland types as well as complex topics related to these dynamic physical environments. Careful syntheses review wetland soils, hydrology, and geomorphology; abiotic constraints for wetland plants and animals; microbial ecology and biogeochemistry; development of wetland plant communities; wetland animal ecology; and carbon dynamics and ecosystem processes. In addition, contributors document wetland regulation, policy, and assessment in the US and provide a clear roadmap for adaptive management and restoration of wetlands. New material also includes an expanded review of the consequences for wetlands in a changing global environment. Ideally suited for wetlands ecology courses, Ecology of Freshwater and Estuarine Wetlands, Second Edition , includes updated content, enhanced images many in color , and innovative pedagogical elements that guide students and interested readers through the current state of our wetlands. Look no further for a refresher of ….
An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features.

Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes , ponds , rivers , streams , springs , bogs , and wetlands. Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and vegetation. Freshwater ecosystems have undergone substantial transformations over time, which has impacted various characteristics of the ecosystems.

Ecology is the scientific study of how organisms interact with each other and with their environment. This includes relationships between individuals of the same species, between different species, and between organisms and their physical and chemical environments. Aquatic ecology includes the study of these relationships in all aquatic environments, including oceans, estuaries, lakes, ponds, wetlands, rivers, and streams.
