WebEcology is the study of how organisms interact with one another and with their physical environment. The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, … WebSpatial patterns are ubiquitous in nature, and ecological systems exhibit patchiness (heterogeneity) across a range of spatial and temporal scales. Landscape ecology is explicitly concerned with understanding how scale affects the measurement of heterogeneity and the scale (s) at which spatial pattern is important for ecological phenomena. bite stick ortho
Hierarchy theory and the landscape … level? or, Words do matter ...
WebLandscape ecologists describe heterogeneity in landscapes in terms of two concepts: patch-matrix and gradients (e.g. Turner et al., 2001; Wagner and Fortin, 2005). The first re-lates to island-biogeography (MacArthur and Wilson, 1967) and metapopulation theory (Hanski and Gilpin, 1997), the second to niche theory (Hutchinson, 1957) and community WebWe trace the rise of macrosystems ecology with respect to preceding theories and present a new hypothesis that integrates the multiple components of macrosystems theory. The … WebHierarchy Theory. It is often useful in ecology to consider at least three hierarchical levels in a study. • The focal level, as derived from the question or objective. • The level above, because it constrains and controls the focal level. • And the level below, which provides the mechanisms or details that explain the focal level. • das lied sofia
