Aquatic science is the study of the various bodies of water that make up our planet including oceanic and freshwater environments. [1] Aquatic scientists study the movement of water, the chemistry of water, aquatic organisms, aquatic ecosystems, the movement of materials in and out of aquatic ecosystems, and the use of water by humans, among other things.
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]
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).
Examples of wetlands classified by the sources of water include tidal wetlands, where the water source is ocean tides; estuaries, water source is mixed tidal and river waters; floodplains, water source is excess water from overflowed rivers or lakes; and bogs and vernal ponds, water source is rainfall or meltwater.
For example, the water at the source is clearer, has a higher oxygen content, lower temperatures, and heterotrophs common species. In the middle, the width usually expands and the species diversity increases due to temperature and oxygen content changes, including aquatic green plants and algae.
Humans often aggregate near coastal habitats to take advantage of ecosystem services. For example, coastal capture fisheries from mangroves and coral reef habitats are estimated to be worth a minimum of $34 billion per year. [64] Yet, many of these habitats are either marginally protected or not protected.
For example, the site’s Turtle Lagoon exhibit mimics the sea creature’s natural surroundings,and the Open Ocean exhibit holds 18,000 gallons of saltwater and plays host to more than 50 species ...
Oceanic nekton comprises aquatic animals largely from three clades: Vertebrates (phylum Chordata ), particularly pelagic fish , cetaceans and sea turtles , form the largest contribution; these animals have endoskeletons made of bones and cartilages and propel themselves via a powerful tail and fan / paddle -shaped appendages such as fins ...
