Freshwater habitats can be classified by different factors, including temperature, light penetration, nutrients, and vegetation. There are three basic types of freshwater ecosystems: lentic (slow moving water, including pools , ponds , and lakess ), lotic (faster moving streams , for example creeks and rivers ) and wetlands ( semi-aquatic areas ...
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]

Water birds are a group of birds that rely on aquatic habitats for hunting, resting, and sometimes nesting. [14] Birds that rely on freshwater habitats include birds such as kingfishers, flamingos, and various types of waterfowl. Many species rely on the plants in these freshwater environments for nesting material, habitat, and food.
Invasive species have been introduced to lentic systems through both purposeful events (e.g. stocking game and food species) as well as unintentional events (e.g. in ballast water). These organisms can affect natives via competition for prey or habitat, predation, habitat alteration, hybridization , or the introduction of harmful diseases and ...
The following unifying characteristics make the ecology of running waters unique among aquatic habitats: the flow is unidirectional, there is a state of continuous physical change, and there is a high degree of spatial and temporal heterogeneity at all scales (microhabitats), the variability between lotic systems is quite high and the biota is ...
The presence or absence of fish can also affect habitat use and habitat selection of dytiscids. [9] [10] Some species, such as Oreodytes sanmarkii, occur in exposed areas of waters, [11] whereas many diving beetles species prefer habitats with aquatic plants, [7] [9] [12] especially plants with complex structures, such as sedges and bulrush.
