  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. Spatial analysis - Wikipedia

    en.wikipedia.org/wiki/Spatial_analysis

    The possibility of spatial heterogeneity suggests that the estimated degree of autocorrelation may vary significantly across geographic space. Local spatial autocorrelation statistics provide estimates disaggregated to the level of the spatial analysis units, allowing assessment of the dependency relationships across space.

  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

    Most commonly the elements being measured are spatial patches of different types. Together with spatial configuration, spatial composition is a basic component of landscape heterogeneity indices. [ 1 ]

  7. 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 ...

  8. Serbian Wikipedia - Wikipedia

    en.wikipedia.org/wiki/Serbian_Wikipedia

    The Serbian Wikipedia (Serbian: Википедија на српском језику, Vikipedija na srpskom jeziku) is the Serbian-language version of the free online encyclopedia Wikipedia. Created on 16 February 2003, it reached its 100,000th article on 20 November 2009 before getting to another milestone with the 200,000th article on 6 July ...

  9. 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 ...
