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 ...
A pond in the Oconee River Floodplain in Georgia, whose surface is covered in duckweed but still contains fish. Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the relationships between living organisms in their physical environment.
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]
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.
Vernal pool basins are often characteristics of Mediterranean climates, but occur in many other ecosystems, such as forested areas of the Canadian Shield, where they are difficult to identify because of the forest canopy. [2] Most pools are dry for at least part of the year, and fill with the winter rains, spring snowmelts and rising water tables.
Technically, a body of water can have a water level higher than full pond when the inflow of water into the body greatly exceeds the outflow (such as during a heavy rain event), even if the body of water is not at full flood level. Most lakes and reservoirs have the ability to lower the level of the lake even when it is already significantly ...
Local conditions, such as annual rainfall and slope aspect, can determine runoff amounts. Influxes of runoff can cause sediment deposition in salt ponds, eventually causing infill of the pond to occur. Natural grazing and predation around salt ponds can trample vegetation, increase local erosion, and introduce nutrients to the ecosystem. [1]
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.
