An association can be viewed as a real, integrated entity shaped either by species interactions or by similar habitat requirements, or it can be viewed as merely a common point along a continuum. The former view was championed by American ecologist Frederic Clements , who viewed the association as a whole that was more than the sum of its parts ...
Ecology is a new science and considered as an important branch of biological science, having only become prominent during the second half of the 20th century. [1] Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics.
Core principles and common themes of ecosystem management: [7] [13] Systems thinking: Management has a holistic perspective rather than focusing on a particular level of biological hierarchy in an ecosystem (e.g., only conserving a specific species or only preserving ecosystem functioning).
Ecosystem-based management is an environmental management approach that recognizes the full array of interactions within an ecosystem, including humans, rather than considering single issues, species, or ecosystem services in isolation. [1] It can be applied to studies in the terrestrial and aquatic environments with challenges being attributed ...
The basic unit of syntaxonomy, the organisation and nomenclature of phytosociological relationships, is the "association", defined by its characteristic combination of plant taxa. Sometimes other habitat features such as the management by humans (mowing regime, for example), physiognomy and/or the stage in ecological succession may also be ...
Historical ecology can use archaeological sites within this setting to study past successes and failures of indigenous peoples. The use of swidden fires in Laos is an example of historical ecology as used by current land managers in policy-making. Swidden fires were originally considered a source of habitat degradation.
The term "species group" can be used to describe the manner in which individual organisms group together. In this non-taxonomic context one can refer to "same-species groups" and "mixed-species groups." While same-species groups are the norm, examples of mixed-species groups abound.
Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals , bedrock , soil , plants , and animals .
