2. List of freshwater ecoregions (WWF) - Wikipedia

   en.wikipedia.org/wiki/List_of_freshwater_eco...

   This is a list of freshwater ecoregions as compiled by the World Wildlife Fund (WWF). The freshwater ecoregion system is similar to that for terrestrial ecoregions.The Earth's land surface is divided into eight terrestrial biogeographic realms or ecozones, which contain hundreds of smaller ecoregions.

3. Freshwater ecosystem - Wikipedia

   en.wikipedia.org/wiki/Freshwater_ecosystem

   There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time). Limnology (and its branch freshwater biology) is a study about freshwater ...

4. Aquatic ecosystem - Wikipedia

   en.wikipedia.org/wiki/Aquatic_ecosystem

   An aquatic ecosystem is an ecosystem found in and around a body of water, in contrast to land-based terrestrial ecosystems. Aquatic ecosystems contain communities of organisms—aquatic life—that are dependent on each other and on their environment. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. [1]

5. Lists of ecoregions - Wikipedia

   The WWF uses three main classifications: Biogeographic realms (also called ecozones), biomes (also called major habitat types), and ecoregions. [1] [2] Global 200 ecoregions (WWF), 238 single or combined ecoregions identified by the World Wildlife Fund (WWF) as priorities for conservation.

   This is a list of freshwater ecoregions in Latin America and the Caribbean, as identified by the World Wildlife Fund (WWF). The WWF divides the Earth's land surface into ecoregions, defined as "large area[s] of land or water containing a distinct assemblage of natural communities and species". Ecoregions are grouped into complexes and ...

7. Freshwater biology - Wikipedia

   These alterations affect water temperature, water flow patterns, and increase sediment, destroying important habitat conditions for many aquatic organisms and reducing water quality. [ 16 ] An area of contention regarding the pollution of streams and rivers is the concept that the pollution upstream affects the people downstream. [ 16 ]

8. Marine ecosystem - Wikipedia

   en.wikipedia.org/wiki/Marine_ecosystem

   In addition to providing many benefits to the natural world, marine ecosystems also provide social, economic, and biological ecosystem services to humans. Pelagic marine systems regulate the global climate, contribute to the water cycle, maintain biodiversity, provide food and energy resources, and create opportunities for recreation and ...

9. General Bathymetric Chart of the Oceans - Wikipedia

   en.wikipedia.org/wiki/General_Bathymetric_Chart...

   The General Bathymetric Chart of the Oceans (GEBCO) is a publicly available bathymetric chart of the world's oceans. The project was conceived with the aim of preparing a global series of charts showing the general shape of the seafloor. Over the years it has become a reference map of the bathymetry of the world's oceans for scientists and others.
