Lake Hāwea, New Zealand. Limnology (/ lɪmˈnɒlədʒi / lim-NOL-ə-jee; from Ancient Greek λίμνη (límnē) 'lake' and -λογία (-logía) '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 ...
e. An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. [1] Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as ...
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
Shell growth in estuaries is an aspect of marine biology that has attracted a number of scientific research studies. Many groups of marine organisms produce calcified exoskeletons , commonly known as shells , hard calcium carbonate structures which the organisms rely on for various specialized structural and defensive purposes.
Landscape limnology is the spatially explicit study of lakes, streams, and wetlands as they interact with freshwater, terrestrial, and human landscapes to determine the effects of pattern on ecosystem processes across temporal and spatial scales. Limnology is the study of inland water bodies inclusive of rivers, lakes, and wetlands; landscape ...
Marine ecosystems are characterized by the biological community of organisms that they are associated with and their physical environment. Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Marine ecosystems are important sources of ecosystem services and food and ...
The River Continuum Concept (RCC) is a model for classifying and describing flowing water, in addition to the classification of individual sections of waters after the occurrence of indicator organisms. [1] The theory is based on the concept of dynamic equilibrium in which streamforms balance between physical parameters, such as width, depth ...
The estuarine system of the North Carolina National Estuarine Research Reserve is the third largest in the country, encompassing more the 10,000 acres (4,000 ha). This system is of prime economic importance to the coastal area—90 percent of the commercial seafood species caught in the state spends at least part of their lives in an estuary.
