  2. Benthos - Wikipedia

    en.wikipedia.org/wiki/Benthos

    These organisms can be used to indicate the presence, concentration, and effect of water pollutants in the aquatic environment. Some water contaminants—such as nutrients, chemicals from surface runoff, and metals [20] —settle in the sediment of river beds, where many benthos reside. Benthos are highly sensitive to contamination, so their ...

  3. Benthic boundary layer - Wikipedia

    en.wikipedia.org/wiki/Benthic_boundary_layer

    The BBL is generated by the friction of the water moving over the surface of the substrate, which decrease the water current significantly in this layer. [2] The thickness of this zone is determined by many factors, including the Coriolis force. The benthic organisms and processes in this boundary layer echo the water column above them. [2]

  4. Benthic zone - Wikipedia

    en.wikipedia.org/wiki/Benthic_zone

    Benthos are the organisms that live in the benthic zone, and are different from those elsewhere in the water column; even within the benthic zone variations in such factors as light penetration, temperature and salinity give rise to distinct differences, delineated vertically, in the groups of organisms supported. [10]

  5. Oceanic physical-biological process - Wikipedia

    en.wikipedia.org/wiki/Oceanic_physical...

    Water flow can be described as laminar or turbulent. [2] Laminar flow is characterized by smooth motion: neighboring particles advected by such a flow will follow similar paths. Turbulent flow is dominated by re-circulation, whorls, eddies and apparent randomness. In such a flow particles which are neighbors at one moment can find themselves ...

  6. Phytobenthos - Wikipedia

    en.wikipedia.org/wiki/Phytobenthos

    Other physical and chemical conditions that also determine phytobenthos distributions include flow, acidity, nutrient, temperature, and the community's composition. [1] Water flow can determine the types and distributions of phytobenthos, especially in the stream communities where the water is constantly moving. [ 1 ]

  7. Aquatic locomotion - Wikipedia

    en.wikipedia.org/wiki/Aquatic_locomotion

    The legs of water beetles have little hairs which spread out to catch and move water back in the power stroke, but lay flat as the appendage moves forward in the return stroke. Also, one side of a water beetle leg is wider than the others and is held perpendicular to the motion when pushing backward, but the leg rotates when the limb returns ...

  8. Benthic-pelagic coupling - Wikipedia

    en.wikipedia.org/wiki/Benthic-pelagic_coupling

    Benthic-pelagic coupling are processes that connect the benthic zone and the pelagic zone through the exchange of energy, mass, or nutrients. These processes play a prominent role in both freshwater and marine ecosystems and are influenced by a number of chemical, biological, and physical forces that are crucial to functions from nutrient cycling to energy transfer in food webs.

  9. Ecohydrology - Wikipedia

    en.wikipedia.org/wiki/Ecohydrology

    Conceptual model describing the mechanisms of water flow attenuation within a beaver wetland with an unconfined floodplain. Ecohydrology (from Greek οἶκος, oikos, "house(hold)"; ὕδωρ, hydōr, "water"; and -λογία, -logia) is an interdisciplinary scientific field studying the interactions between water and ecological systems.
