Kevin N. Laland. , and. Handling Editor James Thomson. PDF PLUS. Abstract. Full Text. More. Abstract. Niche construction theory (NCT) explicitly recognizes environmental modification by organisms (“niche construction”) and their legacy over time (“ecological inheritance”) to be evolutionary processes in their own right.
An ecosystem has two components the biotic components consisting of living things, and the abiotic portion, consisting of elements that are not alive. The non living constituents are said to include the following category, habitat, gases, solar radiation, temperature, moisture and inorganic and organic nutrients.
Theoretical and empirical studies of niche construction are increasing in importance as foci in evolutionary ecology. This special edition presents theoretical and empirical research that illustrates the significance of niche construction to the field.
Niche construction theory is a branch of evolutionary biology that focuses on the capacity of organisms to perturb and modify their environments through their metabolisms, activities, and choices (Odling-Smee et al. 2003).
These different understandings of the who, what and how of nature’s construction turn largely on the relationships between the process of conceptual construal and of materially constructing, but unfortunately use of the noun ‘construction’ obscures the relationships at issue between the process and the outcome of construction.
Biophysical geographers understand and employ scale much as ecologists do (where it is also much debated), but cartographers, Geographic Information Scientists, and espe-cially human geographers have various other ideas of scale and its theoretical and methodological implications.
