For example, ecosystems can be quite different if situated in a small depression on the landscape, versus one present on an adjacent steep hillside. [ 9 ] : 39 [ 10 ] : 66 Other external factors that play an important role in ecosystem functioning include time and potential biota , the organisms that are present in a region and could ...
[13] [112] Ecosystem science, both basic and applied, began to compete with theoretical ecology (then called evolutionary ecology and also mathematical ecology). Eugene Odum, who published a very popular ecology textbook in 1953, became the champion of the ecosystem. In his publications, Odum called for ecology to have an ecosystem and applied ...
Ecosystems may be habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes. Ecosystem ecology is the science of determining the fluxes of materials (e.g. carbon, phosphorus) between different pools (e.g., tree biomass, soil organic material).
Historical ecology revises the notion of the ecosystem and replaces it with the landscape. While an ecosystem is static and cyclic, a landscape is historical. While the ecosystem concept views the environment as always trying to return to a state of equilibrium, the landscape concept considers "landscape transformation" to be a process of ...
Examples include areas between grassland and forest, estuaries and lagoon, freshwater and sea water etc. An ecotone may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). [3]
Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.
For example: Edward Said notes that the Tarzan depicted by Johnny Weissmuller was a resident of the jungle representing the savage, untamed and wild, yet still a white master of it; [29] and in his essay "An Image of Africa" about Heart of Darkness Nigerian novelist and theorist Chinua Achebe notes how the jungle and Africa become the source of ...
