Prairie Pothole
The Prairie Pothole Region (PPR) is an expansive area of the northern Great Plains that contains thousands of shallow wetlands known as potholes. These potholes are the result of glacier activity in the Wisconsin glaciation, which ended about 10,000 years ago. The decaying ice sheet left behind depressions formed by the uneven deposition of till as buried ice blocks melted in ground moraines. These depressions are called potholes, glacial potholes, kettles, or kettle lakes. They fill with water in the spring, creating wetlands, which range in duration from temporary to semi-permanent. The region covers an area of about 800,000 sq. km and expands across three Canadian provinces (Saskatchewan, Manitoba, and Alberta) and five U.S. states (Minnesota, Iowa, North and South Dakota, and Montana). The hydrology of the wetlands is variable, which results in long term productivity and biodiversity. The PPR is a prime spot during breeding and nesting season for millions of migrating wate ...

Ranunculus
''Ranunculus'' is a large genus of about 1750 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots. The genus is distributed worldwide, primarily in temperate and montane regions. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup '' Ranunculus repens'', which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup '' Ranunculus bulbosus'' and the much taller meadow buttercup '' Ranunculus acris''. In ornamental gardens, all three are often regarded as weeds. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds. The water crowfoots (''Ranunculus'' subgenus ''Batrachium''), which grow in still or running water, are sometimes treated in a sep ...

Lemnoideae
Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family ( Araceae), so often are classified as the subfamily Lemnoideae within the family Araceae. Other classifications, particularly those created prior to the end of the twentieth century, place them as a separate family, Lemnaceae. These plants have a simple structure, lacking an obvious stem or leaves. The greater part of each plant is a small organized " thallus" or " frond" structure only a few cells thick, often with air pockets (aerenchyma) that allow it to float on or just under the water surface. Depending on the species, each plant may have no root or may have one or more simple rootlets. Reproduction is mostly by asexual budding (vegetative reproduction), which occurs from a meristem enclosed at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoenoplectus Pungens
''Schoenoplectus pungens'' is a species of flowering plant in the sedge family known as common threesquare, common three-square bulrush and sharp club-rush. It is a herbaceous emergent plant that is widespread across much of North and South America as well as Europe, New Zealand and Australia.Acevedo-Rodríguez, P. & Strong, M.T. (2012). Catalogue of seed plants of the West Indies. Smithsonian Contributions to Botany 98: 1-1192. Habitat Threesquare is found in open, sun-lit marshes and along the shores of lakes and ponds, in water up to deep. It is resistant to fire. Description ''Schoenoplectus pungens'' is a long-lived perennial herb up to tall. The foliage is dark green, rough and dense. The small flowers are grouped in dense spikelets, with of 1–7 spikelets on each stem. The seeds are brown. It is closely related to ''S. americanus,'' and many ''S. pungens'' specimens have long been misidentified as ''S. americanus.'' File:Schoenoplectus spp Sturm11.jpg, Painting by ...

Schoenoplectus Tabernaemontani
''Schoenoplectus tabernaemontani'' is a species of flowering plant in the Cyperaceae, sedge family known by the common names softstem bulrush, grey club-rush, and great bulrush. It can be found throughout much of the world; it has been reported from every state in the United States (including Hawaii), and from every province and territory in Canada except Nunavut. It grows in moist and wet habitat, and sometimes in shallow water. ''Schoenoplectus tabernaemontani'' is quite variable in appearance, thus explaining the long list of synonyms that have been created over the years. It is a perennial herb producing dense stands of many narrow erect stems reaching 1–3 m (33–100 inches) in height. It grows from a long rhizome system. The leaves are mostly basal and have wide sheaths around the stems. The inflorescence is generally a panicle of spikelets on long, thin branches which spread, arch, or droop. The spikelets vary in color. There is usually a long, stiff bract alongside each ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoenoplectus Acutus
''Schoenoplectus acutus'' ( syn. ''Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris'' subsp. ''acutus''), called tule , common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word ''tōllin'' , and it was first recognized by the early Spanish explorers and missionaries in New Spain who saw the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City being used to construct shelters by the indigenous inhabitants. Description ''Schoenoplectus acutus'' has a thick, rounded green stem growing to tall, with long, grasslike leaves, and radially symmetrical, clustered, pale brownish flowers. Taxonomy The two varieties are: *''Schoenoplectus acutus'' var. ''acutus'' – northern and eastern North America *''Schoenoplectus acutus'' var. ''occid ...

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Pothole Landscape South Dakota - 53106527617
Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, Brazil and Uruguay, and the steppe of Romania, Ukraine, Russia, and Kazakhstan. Lands typically referred to as "prairie" (a French loan word) tend to be in North America. The term encompasses the lower and mid-latitude of the area referred to as the Interior Plains of Canada, the United States, and Mexico. It includes all of the Great Plains as well as the wetter, hillier land to the east. From west to east, generally the drier expanse of shortgrass prairie gives way to mixed grass prairie and ultimately the richer and wetter soils of the tallgrass prairie. In the U.S., the area is constituted by most or all of the states, from north to south, of North ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater Recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table surface. Groundwater recharge also encompasses water moving away from the water table farther into the saturated zone. Recharge occurs both naturally (through the water cycle) and through anthropogenic processes (i.e., "artificial groundwater recharge"), where rainwater and/or reclaimed water is routed to the subsurface. The most common methods to estimate recharge rates are: chloride mass balance (CMB); soil physics methods; environmental and isotopic tracers; groundwater-level fluctuation methods; water balance (WB) methods (including groundwater models (GMs)); and the estimation of baseflow (BF) to rivers.

Groundwater
Groundwater is the water present beneath Earth's surface in rock and Pore space in soil, soil pore spaces and in the fractures of stratum, rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is Groundwater recharge, recharged from the surface; it may discharge from the surface naturally at spring (hydrosphere), springs and Seep (hydrology), seeps, and can form oasis, oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction water well, wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought o ...
