Freshwater ecosystems have undergone substantial transformations over time, which has impacted various characteristics of the ecosystems. [4] Original attempts to understand and monitor freshwater ecosystems were spurred on by threats to human health (for example cholera outbreaks due to sewage contamination). [5]
Freshwater ecosystem. Freshwater ecosystems are a subset of Earth's aquatic ecosystems that include the biological communities inhabiting freshwater waterbodies such as lakes, ponds, rivers, streams, springs, bogs, and wetlands. [16] They can be contrasted with marine ecosystems, which have a much higher salinity. Freshwater habitats can be ...
Oxsjön, a lake in Sweden. Freshwater biology focuses on environments like lakes. 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 ...
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]
Limnology (/ l ɪ m ˈ n ɒ l ə dʒ i / lim-NOL-ə-jee; from Ancient Greek λίμνη (límnē) 'lake' and -λογία 'study of') is the study of inland aquatic ecosystems. [1] The study of limnology includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water.
A freshwater swamp forest is a type of wetland ecosystem characterized by its unique hydrology and vegetation. These forests are typically found in low-lying areas, riverbanks, and floodplains where there is a consistent supply of freshwater. [3]
A freshwater ecoregion is a large area encompassing one or more freshwater systems that contains a distinct assemblage of natural freshwater communities and species. The freshwater species, dynamics, and environmental conditions within a given ecoregion are more similar to each other than to those of surrounding ecoregions and together form a ...
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.
