  2. Pond - Wikipedia

    en.wikipedia.org/wiki/Pond

    The technical distinction between a pond and a lake has not been universally standardized. Limnologists and freshwater biologists have proposed formal definitions for pond, in part to include 'bodies of water where light penetrates to the bottom of the waterbody', 'bodies of water shallow enough for rooted water plants to grow throughout', and 'bodies of water which lack wave action on the ...

  3. Garden pond - Wikipedia

    en.wikipedia.org/wiki/Garden_pond

    This garden pond has two ponds separated by a waterfall with a one-foot drop; generally, the fish in the upper pond are smaller, and ones in the lower pond are larger. Ponds may be created by natural processes or by people; however, the origin of the hole in the ground makes little difference to the kind of wildlife that will be found in the pond.

    The term limnology was coined by François-Alphonse Forel (1841–1912) who established the field with his studies of Lake Geneva.Interest in the discipline rapidly expanded, and in 1922 August Thienemann (a German zoologist) and Einar Naumann (a Swedish botanist) co-founded the International Society of Limnology (SIL, from Societas Internationalis Limnologiae).

  5. Freshwater ecosystem - Wikipedia

    Lentic ecosystems can be compared with lotic ecosystems, which involve flowing terrestrial waters such as rivers and streams. Together, these two ecosystems are examples of freshwater ecosystems. Lentic systems are diverse, ranging from a small, temporary rainwater pool a few inches deep to Lake Baikal, which has a maximum depth of 1642 m. [10]

  6. Pond life - Wikipedia

    Frogs in a pond. Pond life is an umbrella term for all life forms found in ponds.Although there is considerable overlap with the species lists for small lakes and even slow-flowing rivers, pond life includes some species not found elsewhere, and as a biome it represents a unique assemblage of species.

  7. Lake ecosystem - Wikipedia

    en.wikipedia.org/wiki/Lake_ecosystem

    Free-floating macrophytes can occur anywhere on the system's surface. [2] Aquatic plants are more buoyant than their terrestrial counterparts because freshwater has a higher density than air. This makes structural rigidity unimportant in lakes and ponds (except in the aerial stems and leaves).

    Perseverance Bay Salt Pond, St. Thomas, USVI. Salt ponds are a natural feature of both temperate and tropical coastlines. These ponds form a vital buffer zone between terrestrial and marine ecosystems. Contaminants such as sediment, nitrates and phosphates are filtered out by salt ponds before they can reach the ocean.
