Wildlife Population Restoration - Session 7 - Terms Flashcards
Define ‘Patch Dynamics’
The incursion/melding of patches over time through disturbance events and successional growth of vegetation
Define ‘Patch Connectivity’
The degree of adjacency of patches w/ similar conditions in a landscape
Define ‘Patch Isolation’
The distance from one patch to the next patch of the same type
Define ‘Fragmentation’
The breaking up of contiguous environmental/habitat patches into smaller, more disjunct, and more isolated patches of different types
Define ‘Connectivity’
The extent to which a species/population can move among landscape elements in a mosaic of habitats
Define ‘Permeability’
The degree to which an organism can move among patches within a landscape
Define ‘Faunal Relaxation’
When wildlife species are lost from an isolated environment
Define ‘Edge Effect’
Incursion of microclimate/vegetation into a patch, typically forested, from a disturbed edge or opening
Define ‘Edge Contrast’
The degree of difference in vegetation structure between two adjacent patches
Define ‘Habitat Heterogeneity’
The degree of discontinuity in environmental conditions across a landscape for a particular species
Define ‘Ecotones’
Discontinuities in environmental conditions - refers to the new area (transition area) made by merging two seperate zones together
Define ‘Ecoclines’
Broader gradations in conditions over areas of greater goegraphic extent
Define ‘Corridors’
A linear habitat which connects two or more larger blocks of habitat
