I would have preferred the 95 pages of references to have been assigned to the respective chapters, and the reader given some key titles for further reading. Because the land surrounding most playas is cultivated, annual and exotic plant species are common invaders Smith and Haukos 2002. Atlantic white cedar swamps may occur in isolated basins, along lake shorelines, shoreward of coastal tidal marshes, on river floodplains, or on slopes Laderman 1989. Wetlands generally include swamps, marshes, bogs, and similar areas. Because of these groundwater connections, prairie potholes are interlinked wetland complexes.
Sphagnum also maintains waterlogging in the substrate. Prairie potholes are especially important ecologically and economically because they are the major waterfowl breeding area in North America. Focusing on the ecology of key organisms, each chapter is relevant to wetland regulation and assessment, wetland restoration, how flood pulses control the ecology of most wetland complexes, and how human regulation of flood pulses threatens wetland biotic integrity. 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. There are probably more than 30,000 of these small circular depressions, which are thought to result from a combination of dissolution of subsurface materials and wind action Haukos and Smith 2003. Additional species in these tall pocosins may include red maple Acer rubrum , black gum Nyssa sylvatica , and sweetbay Magnolia virginiana.
Note that the tallest trees are in the center, which is usually the deepest part of the wetland. Lakes and marshes in the Sandhills region are interconnected with the regional groundwater LaBaugh 1986b; Winter 1986. Pocosin communities, pond cypress Taxodium ascendens savannas, and pond cypress ponds are more common in bays on the lower Coastal Plain, which tend to have soils that are more organic. All in one book--I'm impressed! The value of these wetlands to people stems primarily from their roles in nutrient cycling, water supplies, disturbance flood regulation, and wastewater treatment. Tables are sometimes lengthy and complex. Vegetation development in many bogs may follow the model of hydrarch succession, or terrestrialization, at least to some degree see Chapter 5.
The wetlands described here reflect a North American perspective and are chosen to be representative of the variety of wetland types rather than totally inclusive of the range of wetland plant and animal communities that occur on this continent. The text of this second edition is actually somewhat shorter than the first. Small cover images, top to bottom: Muskrat Ondatra zibethicus ; photo courtesy of Michele Rundquist-Franz. Major parts of the Everglades wetlands now have been drained for agriculture and urbanization, and the water flows in the remaining areas are fragmented by canals, large water conservation areas, and roads and drainage ditches and pipes. Canopy species include redbay Persea borbonia and sweetbay as well as dahoon holly Ilex cassine and pond apple Annona glabra , with a dense layer of shrubs underneath.
Bird watching and waterfowl hunting are major human activities related to wetlands. For example, mud flats devoid of vegetation, floodplains that primarily flood in winter outside the growing season, and flooded areas of floodplains where anoxic soil conditions do not develop are all probably ecological wetlands but may not fit some legal definitions. Even though deepwater swamps are usually flooded, water levels may vary seasonally and annually. Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful a in facilitating communication among the diverse research groups involved in wetlands research b in bringing researchers and managers together and c in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. The book is divided into two parts-bioassessment and wildlife management.
Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Separate chapters discuss how to manage fish, waterbirds, and mosquitoes in wetlands. BookShelf allows visitors, otherwise looking for free-content to enjoy more for less. Category: Nature Author : Darold P. The vast majority of amphibians are linked to wetlands, even if only for reproduction.

Prominent scholars help students understand both general concepts of different wetland types as well as complex topics related to these dynamic physical environments. The relatively constant supply of groundwater maintains saturated conditions most of the time, and the water chemistry reflects the mineralogy of the surrounding and underlying substrates. Depression meadows are dominated by graminoids, including grasses such as Panicum, Leersia, and Dicanthelium; sedges such as Carex; and rushes including Juncus and Rhynchospora as well as a variety of other herbaceous plants. Cypress dome wetland with pond cypress Taxodium ascendens trees in Florida. Would serve as an excellent textbook for classes focusing on wetlands, wetland ecology, and related classes where system ecology and function may be of interest. Additionally, hydric soils are not extensive.
Since many deepwater swamps are found along the floodplains of rivers, their soils generally have adequate nutrients, and these forests are relatively productive. Precipitation is their predominant source of water, and these shallow basins range from nearly permanently inundated to frequently dry, depending on their depth and local rainfall patterns. On flat areas or at the base of slopes, small wetlands can develop around these points of discharge Fig. Hydrology is the factor most influenced by geomorphology and climate, and hydrology is also the primary conduit for the control of the physico-chemical environment and the biotic interactions in wetlands. Would serve as an excellent textbook for classes focusing on wetlands, wetland ecology, and related classes where system ecology and function may be of interest.
