We develop a hierarchical model of heterogeneity that provides a framework for classifying patch structure across a range of scales. Patches at lower levels in the hierarchy are more simplistic and correspond to the traditional view of patches. At levels approaching the upper bounds of the hierarchy the internal structure becomes more heterogeneous and boundaries more ambiguous. At each level in the hierarchy, patch structure will be influenced by both contrast among patches as well as the… 
Analysis of patterns in hierarchically structured landscapes
TLDR
Examination of hierarchically structured maps generated by randomly selecting site suitability at successively finer scales shows that the global fraction of suitable sites, P, does not fully explain observed changes in landscape properties.
Scale dependency and the expression of hierarchical structure in Delphinium patches
TLDR
It is predicted that because of the lack of dominant and strongly scale-dependent processes, microlandscapes such as Delphinium meadows, may be less likely to exhibit well-defined hierarchical structure than larger-scale landscapes, especially those heavily altered by human activities.
Patch Dynamics: The Transformation of Landscape Structure and Function
One of the most important developments in modern ecology is the recognition that heterogeneity, or spatial pattern, is a key part of the structure and functioning of nature. No person working to
MODELING THE LANDSCAPE AS A DYNAMIC MOSAIC OF PATCHES: SOME COMPUTATIONAL ASPECTS
The only thing that is certain and absolute about Nature is its patchiness. Patchiness is ubiquitous, occurring across systems, organizational levels, and spatio-temporal scales. Traditional modeling
Hierarchical patch dynamics and animal movement pattern
TLDR
A new method based on first-passage time on the pathway of a foraging seabird, the Antarctic petrel, is applied to quantify the spatial scale and turnover of their foraging areas and it is suggested that the findings reflect the spatial dynamics of krill in the area.
A Spatial Patch Dynamic Modeling Approach to Pattern and Process in an Annual Grassland
Landscapes are hierarchical mosaics of patches that differ in their age, size, shape, content, and other aspects. The Jasper Ridge serpentine grassland exemplifies hierarchical patchiness and
Which spatial heterogeneity framework? Consequences for conclusions about patchy population distributions.
TLDR
These results still supported the notion that the beetle exists as a metapopulation, a structure thought to be rare because it ignores habitat quality and landscape conditions, and exemplify the simultaneous importance of local patch attributes and broad-scale and/or gradient variables that are commonly overlooked in patch studies.
Ecological mechanisms and landscape ecology
TLDR
This work presents an approach to research that focuses on how individual-level mechanisms operating in a heterogeneous mosaic produce ecological patterns that are spatially dependent.
Hierarchical, Multi-scale decomposition of species-environment relationships
TLDR
An adaptation of existing variance partitioning methods toompose species-environment relationships in hierarchically-structured, multi-scaled data sets and allows comprehensive analysis of the interaction of factors across scales and facilitates ecological interpretation in theoretical terms is presented.
Splitting, shrinking, and disappearing patches: a dynamic view of habitat loss
TLDR
A dynamic model of habitat fragmentation is investigated, describing the local (fine-scale) events and their frequencies observable on such a landscape, demonstrating that the effective loss caused by the removal of a single habitat site can be several times higher than the actual habitat loss.

Ecological Systems in Hierarchical Perspecitive: Breaks in Community Structure and Other Consequences
TLDR
A hierarchical structure of the environment appears promising in accounting for some poorly explained community-level phenomena, such as correlation between the species range and abundance, and differences between abundance structures of communities in rigorous and less severe environments.
Population Responses to Patchy Environments
TLDR
An environmental patchwork which exerts powerful influences on the distri­ butions of organisms, their interactions, and their adaptations is considered.
A Hierarchical Concept of Ecosystems.
"Ecosystem" is an intuitively appealing concept to most ecologists, but, in spite of its widespread use, the term remains diffuse and ambiguous. The authors of this book argue that previous attempts
Ecological Scale and Habitat Use
TLDR
This analysis suggests species whose patterns of resource and habitat use probably depart from classical interpretations of species coexistenceProbably depart from Classical interpretations ofspecies coexistence, and it is probably premature to assess the role of habitat selection in the structure of ecological systems until the results of habitat scaling are reported.
Ecological neighborhoods: scaling environmental patterns
TLDR
There is no single ecological neighborhood for any given organism, but rather a number of neighborhoods, each appropriate to different processes, which provide the scales necessary for assessing environmental patterning relative to particular ecological processes for a given species.
Spatial Scaling in Ecology
Acts in what Hutchinson (1965) has called the 'ecological theatre' are played out on various scales of space and time. To understand the drama, we must view it on the appropriate scale. Plant
The ecological concept of disturbance and its expression at various hierarchical levels
TLDR
Using these definitions, disturbance can be unequivocally identified and associated with various specific ecological levels of organization and application of the concept will advance as refined models of the hierarchical structure of ecological systems are elaborated.
