List of Fishing Topics By Subject - Aquatic Ecosystems - Fresh Water Ecosystems

Fresh Water Ecosystems

  • Freshwater ecosystems
  • Brackish marsh – Brackish marshes develop by salt marshes where a significant freshwater influx dilute the seawater to brackish levels of salinity.
  • Freshwater biology – Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of Limnology.
  • Freshwater biomes –
  • Freshwater fish – Freshwater fish are fish that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 0.05%.
  • Freshwater marsh – A freshwater marsh is a marsh that contains fresh water.
  • Freshwater swamp forest – Freshwater swamp forests, or flooded forests,
  • Hyporheic zone – The hyporheic zone is a region beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water.
  • Lake ecosystems
  • Landscape limnology – Landscape limnology is the spatially explicit study of lakes, streams, and wetlands as they interact with the freshwater, terrestrial, and human landscapes to determine the effects of pattern on ecosystem processes across temporal and spatial scales.
  • Limnology – Limnology, also called freshwater science, is the study of inland waters.
  • Lake stratification – Lake stratification is the separation of lakes into three layers:
  • Macrophyte – A macrophyte is an aquatic plant that grows in or near water and is either emergent, submergent, or floating.
  • Pond – A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake.
  • Fish pond – A fish pond, or fishpond, is a controlled pond, artificial lake, or reservoir that is stocked with fish and is used in aquaculture for fish farming, or is used for recreational fishing or for ornamental purposes.
  • Rheotaxis – Rheotaxis is a form of taxis seen in many aquatic organisms, e.g., fish, whereby they will turn to face into an oncoming current.
  • River ecosystems River ecosystem
  • Stream bed – A stream bed is the channel bottom of a stream, river or creek; the physical confine of the normal water flow.
  • Stream pool – A stream pool, in hydrology, is a stretch of a river or stream in which the water depth is above average and the water velocity is quite below average.
  • Trophic state index – primary determinants of a body of water's trophic state index .
  • Upland and lowland – In studies of the ecology of freshwater rivers, habitats are classified as upland and lowland.
  • Water garden –
  • Wetland – A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on characteristics that distinguish it as a distinct ecosystem.
  • Environmental quality – Freshwater environmental quality parameters are the natural and man-made chemical, biological and microbiological characteristics of rivers, lakes and ground-waters, the ways they are measured and the ways that they change.

Famous quotes containing the words fresh and/or water:

    In his very rejection of art Walt Whitman is an artist. He tried to produce a certain effect by certain means and he succeeded.... He stands apart, and the chief value of his work is in its prophecy, not in its performance. He has begun a prelude to larger themes. He is the herald to a new era. As a man he is the precursor of a fresh type. He is a factor in the heroic and spiritual evolution of the human being. If Poetry has passed him by, Philosophy will take note of him.
    Oscar Wilde (1854–1900)

    I think of the nestling fallen into the deep grass,
    The turtle gasping in the dusty rubble of the highway,
    The paralytic stunned in the tub, and the water rising,—
    All things innocent, hapless, forsaken.
    Theodore Roethke (1908–1963)
