  2. Spatial heterogeneity - Wikipedia

    en.wikipedia.org/wiki/Spatial_heterogeneity

    There exist two main types of spatial heterogeneity. The spatial local heterogeneity categorises the geographic phenomena whose its attributes' values are significantly similar within a directly local neighbourhood, but which significantly differ in the nearby surrounding-areas beyond this directly local neighbourhood (e.g. hot spots, cold spots).

  3. Hybrid zone - Wikipedia

    en.wikipedia.org/wiki/Hybrid_zone

    Hybrid zones can form from secondary contact. A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. . Hybrid zones can form in situ due to the evolution of a new lineage [1] [page needed] but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their ...

  4. Spatial configuration - Wikipedia

    en.wikipedia.org/wiki/Spatial_configuration

    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 .

  5. Huffaker's mite experiment - Wikipedia

    en.wikipedia.org/wiki/Huffaker's_mite_experiment

    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.

  6. Spatial composition - Wikipedia

    en.wikipedia.org/wiki/Spatial_composition

    In landscape ecology, spatial composition describes the content of a landscape in terms of the number of different categories of elements existing in the landscape and their proportions. Most commonly the elements being measured are spatial patches of different types.

  7. Metapopulation - Wikipedia

    en.wikipedia.org/wiki/Metapopulation

    Although the term metapopulation had not yet been coined, the environmental factors of spatial heterogeneity and habitat patchiness would later describe the conditions of a metapopulation relating to how groups of spatially separated populations of species interact with one another. Huffaker's experiment is significant because it showed how ...

  8. Stewart Fotheringham - Wikipedia

    en.wikipedia.org/wiki/Stewart_Fotheringham

    In GWR, regression coefficients (parameters) are estimated locally for each geographic location or point, allowing for the modeling of spatial heterogeneity. [6] Geographically Weighted Regression is a cornerstone of GIS and spatial analysis, and is built into ArcGIS , as a package for the R (programming language) , and as a plugin for QGIS .

  9. Modifiable areal unit problem - Wikipedia

    en.wikipedia.org/wiki/Modifiable_areal_unit_problem

    MAUP can be used as an analytical tool to help understand spatial heterogeneity and spatial autocorrelation. This topic is of particular importance because in some cases data aggregation can obscure a strong correlation between variables, making the relationship appear weak or even negative. Conversely, MAUP can cause random variables to appear ...
