Spatial heterogeneity is a property generally ascribed to a landscape or to a population. It refers to the uneven distribution of various concentrations of each ...
A landscape with structure and pattern implies that it has spatial heterogeneity, or the uneven distribution of objects across the landscape. [6] Heterogeneity is a key element of landscape ecology that separates this discipline from other branches of ecology. Landscape heterogeneity is able to quantify with agent-based methods as well.

Spatial ecology studies the ultimate distributional or spatial unit occupied by a species.In a particular habitat shared by several species, each of the species is usually confined to its own microhabitat or spatial niche because two species in the same general territory cannot usually occupy the same ecological niche for any significant length of time.
Spatial biology is the study of biomolecules and cells in their native three-dimensional context. Spatial biology encompasses different levels of cellular resolution including (1) subcellular localization of DNA, RNA, and proteins, (2) single-cell resolution and in situ communications like cell-cell interactions and cell signaling, (3) cellular neighborhoods, regions, or microenvironments, and ...
For conservation biology purposes, metapopulation models must include (a) the finite nature of metapopulations (how many patches are suitable for habitat), and (b) the probabilistic nature of extinction and colonisation. Also, in order to apply these models, the extinctions and colonisations of the patches must be asynchronous.
Spatial heterogeneity is the variation of an environment over space (e.g. differences between oranges and balls). Huffaker was expanding upon Gause's experiments by further introducing heterogeneity. Gause's experiments had found that predator and prey populations would become extinct regardless of initial population size.
In landscape ecology, spatial configuration describes the spatial pattern of patches in a landscape. Most traditional spatial configuration measurements take into account aspects of patches within the landscape, including patches' size, shape, density, connectivity and fractal dimension .
The first test of the spatial storage effect was done by Sears and Chesson [10] in the desert area east of Portal, Arizona. Using a common neighbor-removal experiment, they examined whether coexistence between two annual plants, Erodium cicutarium and Phacelia popeii, was due to the spatial storage effect or resource partitioning. The storage ...
