Freshwater ecology has contributed considerably to the advancement of food-web ecology. This has occurred through early application of methodological advances such as stable isotope analysis and description of some of the most detailed food webs, including Little Rock Lake and the Broadstone Stream food...
Figure 2.The lake ecosystem showing the drainage basin with terrestrial photosynthesis (PS) of organic matter, movement of nutrients and dissolved (DOM) and particulate (POM) organic matter in surface water and groundwater flows toward the lake basin, and chemical and biotic alteration of these ma...
Today, a wealth of studies demonstrates that MP have ubiquitously permeated the marine ecosystem, including the polar regions and the deep sea. MP ingestion has been documented for an increasing number of marine species. However, to date, only few studies investigate their biological effects. The ...

SE Asia also is a region of high dependence on freshwater fisheries; for example the Tonle Sap ecosystem (seasonally flooded shallow lake associated with the Mekong River, but not among Earth’s most voluminous 21 lakes) provides 213,000 tonne/y in fisheries, larger than all but one of ...

Lake eutrophication influences ecosystem structure and functioning as well as the distribution and abundance of most species. This fundamental influence is the result of the primary role of nutrients in boosting the biomass and productivity of phytoplankton, setting the scene for many structural and func...
Freshwater lake ecosystem There arefour main constituentsof the living environment that form the freshwater ecosystem, they are as follows. Elements and Compoundsof the ecosystem that are absorbed by organisms that are required as a food source or for respiration. Many of these compounds are required...
1).This factual situation will continue to threaten the Earth's climate system and biodiversity by altering species ranges and abundances, reshuffling biological communities, restructuring food webs and ecosystem functions and generating negative feedbacks to human well-being at the end, especially in ...
a fish ecologist interested in the use of woody debris by lake-dwelling fishes might define the shore zone as extending a distance of the height of the tallest tree in either direction from the shoreline (i.e., the terrestrial zone which supplies wood to the lake plus the aquatic zone that...
