The Montana-based land trust has launched an initiative to secure unprotected private land in the region so that bears can move undisturbed from protected public lands via linkage zones.
Chadwick's proposals for a ban on trapping of midsize and large animals in and around reserves with wolverine populations, and the restriction of trapping in linkage zones between these areas, have real merit.
The design and appropriate distribution of the new systems is aided by remote sensing techniques to locate areas of saline discharge and linkages to zones of groundwater recharge, geographical information systems to arrange the data for land system analysis, and computer models of crops and cropping systems.
Connectivity for large mammals across human-altered landscapes results from movement by individuals that can be described via nested spatial scales as linkages (or zones or areas) with compatible land use types, constrictions that repeatedly funnel movement (as corridors) or impede it (as barriers), and the specific paths (or routes) across completely anthropogenic features (such as highways).
This phase of intraplate tectonism in northern Namibia, focused in discrete structurally defined zones, is coeval with similar phases elsewhere in Africa and suggests some form of trans-continental linkage between these lithospheric zones.
Without long-term climate data from this area, it remains unclear if selection in the course of ongoing aridification could be responsible for heterozygote deficiencies and linkage disequilibria within the transition zone.
Regarding plant linkage level (L p), the transition zone showed higher values than either the arid or the humid zone in 2010 (χ = 16.39, d.f. = 6, P = 0.01); differences among habitats were more marked in San Cristóbal than in Santa Cruz (χ = 13.24, d.f.= 2, P = 0.001) [see Supporting Information Fig. S3 ].
Here we describe the distribution of thermokarst landforms in the continuous permafrost zone of Arctic Alaska, analyze linkages to the underlying surficial geology, and discuss the vulnerability of different types of landscapes to future thaw.
Full line: P = 1.10−5 Fig. 3 Manhattan plot and pattern of linkage disequilibrium (LDheatmap) in the PI33 target zone.
As well, in the gradient-contact zone, significant heterozygote deficiencies and linkage disequilibria, which were mostly restricted to the transition zone, pointed to selection [ 30].
And L.N.G. sales to Europe could further erode that oil price linkage and give relief to a struggling euro zone.
