Movement Corridors : Conservation Bargains or Poor Investments ?

  title={Movement Corridors : Conservation Bargains or Poor Investments ?},
  author={A. U.S. and Cox}
Corridors for movement o f organisms between refuges are confounded with corridors designed for other function~ obscuring an assessment o f cost.effectivenesx The rationales for movement corridors are (1) to lower extinction rate in the sense o f the equilibrium theory, (2) to lessen demographic stochastictty, (3) to stem inbreeding depression, and (4) to ful f i l l an inherent need for movement There is a paucity o f data showing how corridors are used and whether this use lessens extinction… 
Do Habitat Corridors Provide Connectivity?
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
Biological corridors and connectivity
The ability of individual animals to move across complex landscapes is critical for maintaining regional populations in the short term (Fahrig 2003; Cushman 2006), and for species to shift their
The Utility of Movement Corridors in Forested Landscapes
Linking habitat patches with movement corridors to enhance survival of populations in the connected fragments is an appealing idea. However, research regarding corridors provides ambiguous evidence
Conservation o [ Fragmented Populations Fahrig
In this paper we argue that landscape spatial structure is o f central importance in understanding the effects o f f ragmentat ion on populat ion survival Landscape spatial structure is the spatial
Constructing Connectivity: Conservation Corridors and Conservation Politics in East African Rangelands
Conservation corridors are perhaps the most visible expression of the new landscape conservation boom. Seen as the essential connecting structure across increasingly fragmented landscapes, corridors
Argali Sheep (Ovis ammon) Movement Corridors Between Critical Resources in Ikh Nart Nature Reserve, Mongolia
Understanding how animals move through a landscape can reveal corridors or narrow paths of movement that connect discrete parts of a landscape. Identifying corridors can be important for planning
Compensatory behavior of Ensatina eschscholtzii in biological corridors: a field experiment
It is argued that knowledge of a speciesi habitat-specific dispersal behaviors is critical to reliably designating corridors as functional components of reserve design, and that identifying candidate corridor areas on conservation maps might be difficult because animals may show compensatory behavioral responses to different types of habitat separating source and target patches.
Linear conservation areas may function as biological corridors, but they may not mitigate against additional habitat loss
H abitat loss and fragmentation are among the most pervasive threats to the conservation of biological diversity (Wilcove et al. 1986, Wilcox and Murphy 1985). Habitat fragmentation often leads to
Use of Empirically Derived Source‐Destination Models to Map Regional Conservation Corridors
It is argued that analysis of movement across continuously resistant landscapes allows a shift to a broader consideration of how landscape patterns influence connectivity at scales relevant to conservation, and this change in scale and definition of the connectivity problem improves one's ability to find solutions.


The Role of Climatic Change in the Design of Biological Reserves: The Paleoecological Perspective for Conservation Biology
  • R. Graham

  • 1988
The design of areas (refuges, reserves, or preserves) to conserve the biological diversity of terrestrial ecosystems in the face of unprecedented habitat destruction has primarily been based on the
Effects of isolation on the water status of forest patches in the Brazilian Amazon
Patterns of edge-related environmental changes and plant water relations were investigated in the isolated forest reserves of the INPA-WWF Minimum Critical Size of Eco-systems project near Manaus, Brazil early in the wet season, finding no evidence of restriction of water loss in these plants.
The Dynamics and Regulation of Black Bear Ursus americanus Populations in Northern Alberta
Numbers of black bears on the study area varied little from 1968 through 1971. The removal of 26 large adult males in 1971 and 1972 was followed by an apparent increase in the bear population in 1972
The Cooperative Breeding System of the Red‐cockaded Woodpecker
The habitat saturation model of the evolution of cooperative breeding is based on selection between the two life-history strategies exhibited by male red-cockaded woodpeckers, and it is suggested that females sometimes are forced from groups by immigrants or other group members.
The equilibrium theory of island biogeography : fact or fiction?
It is concluded that there is little support for its tenets and the application of the equilibrium theory of island biogeography to nature conservation and ecology is therefore premature.
