The productivity of an ecosystem is influenced by a wide range of factors, including nutrient availability, temperature, and water availability. Understanding ecological productivity is vital because it provides insights into how ecosystems function and the extent to which they can support life.
In his 1950 Ph.D. thesis, Odum gave a novel definition of ecology as the study of large entities (ecosystems) at the "natural level of integration". [12] In the traditional role of an ecologist, one of Odum's doctoral aims was to recognize and classify large cyclic entities (ecosystems).
Ecosystem classifications are specific kinds of ecological classifications that consider all four elements of the definition of ecosystems: a biotic component, an abiotic complex, the interactions between and within them, and the physical space they occupy. Biotic factors of the ecosystem are living things; such as plants, animals, and bacteria ...
Social-ecological systems are based on the concept that humans are a part of—not separate from—nature. [8] This concept, which holds that the delineation between social systems and natural systems is arbitrary and artificial, was first put forth by Berkes and Folke, [9] and its theory was further developed by Berkes et al. [10] More recent research into social-ecological system theory has ...
Several academic programs combine a broad definition of “environmental studies” with analyses of social processes, biological considerations, and the physical environment. A number of social ecology degree-granting programs and research institutes shape the global evolution of the social ecological paradigm. For example, see:
The ecological efficiency of an ecosystem is as a result often no better than an approximation. On the other hand, an approximation may be enough for most ecosystems, where it is important not to get an exact measure of efficiency, but rather a general idea of how energy is moving through its trophic levels.
Socioecology is primarily related to anthropology, geography, sociology, and ecology. Specifically, the term is used in human ecology, the study of the interaction between humans and their environment. Socioecological models of human health examine the interaction of many factors, ranging from narrowest (individual behaviors) to broadest ...
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).
