On the usage and measurement of landscape connectivity
@article{Tischendorf2000OnTU, title={On the usage and measurement of landscape connectivity}, author={Lutz Tischendorf and Lenore Fahrig}, journal={Oikos}, year={2000}, volume={90}, pages={7-19} }
This paper examines the usage and measurement of “landscape connectivity” in 33 recent studies. Connectivity is defined as the degree to which a landscape facilitates or impedes movement of organisms among resource patches. However, connectivity is actually used in a variety of ways in the literature. This has led to confusion and lack of clarity related to (1) function vs structure, (2) patch isolation vs landscape connectivity and, (3) corridors vs connectivity. We suggest the term…

Measuring landscape connectivity: On the importance of within-patch connectivity
- Environmental ScienceLandscape Ecology
- 2019
Many connectivity metrics have been used to measure the connectivity of a landscape and to evaluate the effects of land-use changes and potential mitigation measures. However, there are still gaps in…
How should we measure landscape connectivity?
- Environmental ScienceLandscape Ecology

The methods for measuring landscape connectivity have never been compared or tested for their responses to habitat fragmentation. We simulated movement, mortality and boundary reactions across a wide…
How does landscape structure influence landscape connectivity
- Environmental Science
- 2002
The simulations revealed that the six measures of landscape connectivity were influenced by different aspects of landscape structure, suggesting that: (1) landscape connectivity is a poorly defined concept, and (2) the same landscape may have different landscape connectivity values when different measures of landscapes connectivity are used.
Habitat connectivity in biodiversity conservation

The study of landscape connectivity in conservation has increased considerably since the early part of the 21st century. While the implications of landscape connectivity are self-evident for…
Quantifying Landscape Connectivity: Key Patches And Key Corridors

The problems of habitat loss and fragmentation call for an understanding of how ecological landscapes serve the needs of inhabiting metapopulations. Questions of extreme importance are ( 1 ) how…
Assessing functional connectivity using empirical data
- Environmental SciencePopulation Ecology
- 2008
The current use of connectivity concepts are summarized in terms of both metapopulation and landscape ecology, and recently developed promising techniques in spatial ecology are presented, which will help to improve assessment of species-centered or functional connectivity based on empirical data.
MEASURING LANDSCAPE CONNECTIVITY: THE CHALLENGE OF BEHAVIORAL LANDSCAPE ECOLOGY
- Biology
- 2005
It is suggested that the concept of functional connectivity be bridged to the one of travel costs used in behavioral ecology, which would help define unequivocal operational definitions offunctional connectivity as its measurement would be dictated by its ecological role within specific models (e.g., travel costs within group membership models of foraging theory).
Evaluation of landscape connectivity at community level using satellite-derived NDVI
- Environmental ScienceLandscape Ecology
- 2012
This study uses satellite imagery and network metrics to predict the landscape connectivity at community level for semi-natural herbaceous patches in an urban area near Paris (France) and makes recommendations for ways in which to optimise landscape planning with respect to conservation of urban biodiversity.

Skeptics have questioned the empirical evidence that corridors provide landscape connectivity. Some also have suggested dangers of corridors. We reviewed published studies that empirically addressed…
Using Landscape Indices to Predict Habitat Connectivity
- Environmental Science
- 1996
Nine common indices of habitat pattern were examined and a new pattern index was identified, termed patch cohesion, for which the fit was much better and was found to be insensitive to the details and artifacts of the dispersal model.
Connectivity is a vital element of landscape structure

In a recent FORUM article, Dunning et al. (1992) put forward a framework of landscape processes that stimulated considerable discussion amongst us. We are in general agreement with their ideas, but…

Several important needs are suggested for future research, including continued investigation of scaling issues, development of indices that measure specific components of spatial pattern, and efforts to make point-data analysis more compatible with ecological theory.
Connectivity and complexity in landscapes and ecosystems
- Environmental Science

Simulations of multi-species systems show that, below a critical rate, disturbance regimes have little impact on species richness, but with super-critical rates of disturbance the rate of decrease in species richness depends on the balance between theRate of disturbance and dispersal range.

Low‐vagility organisms that specialize on transitory successional habitats may be especially dependent upon habitat connectivity to maintain population viability. We analyzed the theoretical…

Assessment of the independent effects of habitat affinity and habitat carrying capacity on population distributions revealed that the differential interaction of species with landscape structure was the primary determinant of distributional patterns.
