Ecosystem ecology is philosophically and historically rooted in terrestrial ecology. The ecosystem concept has evolved rapidly during the last 100 years with important ideas developed by Frederic Clements, a botanist who argued for specific definitions of ecosystems and that physiological processes were responsible for their development and persistence. [2]
Environmental education is not restricted to in-class lesson plans. Children can learn about the environment in many ways. Experiential lessons in the school yard, field trips to national parks, after-school green clubs, and school-wide sustainability projects help make the environment an easily accessible topic.
The project Science and the city, for example, took place during the school years 2006-2007 and 2007-2008 involving an intergenerational group of researchers: 36 elementary students (grades 6, 7 & 8) working with their teachers, 6 university-based researchers, parents and community members.
Raymond Lindeman took these ideas further to suggest that the flow of energy through a lake was the primary driver of the ecosystem. Hutchinson's students, brothers Howard T. Odum and Eugene P. Odum , further developed a "systems approach" to the study of ecosystems.
Biogeoclimatic ecosystem classification (BEC) [1] [2] is an ecological classification framework used in British Columbia to define, describe, and map ecosystem-based units at various scales, from broad, ecologically-based climatic regions down to local ecosystems or sites.
In contemporary niche theory, the "impact niche" is defined as the combination of effects that a given consumer has on both a). the resources that it uses, and b). the other consumers in the ecosystem. Therefore, the impact niche is equivalent to the Eltonian niche since both concepts are defined by the impact of a given species on its environment.
The systemic origins of ecosystem-based management are rooted in the ecosystem management policy applied to the Great Lakes of North America in the late 1970s. The legislation created, the "Great Lakes Basin and the Great Lakes Water Quality Agreement of 1978", was based on the claim that "no park is an island", with the purpose to show how strict protection of the area is not the best method ...
To characterize the spatial and temporal heterogeneity of ecosystem functioning at the local and regional scales. [16] [22] To describe the biogeographical patterns of functional diversity at the ecosystem level. [2] To assess the functional diversity at the ecosystem level by determining the EFTs richness and equity in the landscape. [23]
