By studying the mechanisms of interaction between ecosystems and habitat processes, the constraining factors can be identified, and this knowledge can be used to improve the success rate of ecological restoration initiatives.
This raises problems for habitats, species, and for land users, in islands where habitat processes and human interaction with the environment have always been particularly closely linked.
Eigenvector mapping and variation partitioning revealed that spatially independent habitat processes accounted for little of the variation in community composition (2.0%); most variation was attributed either to habitats that were spatially structured (25.6%) or to dispersal independent of habitat (28.0%).
From the outset, the Bush administration has made no secret of its misgivings about the critical habitat process, saying that the designations -- particularly when required under court order -- divert the Fish and Wildlife Service from the more important task of determining which species deserve federal protection.
However, the significance of environmental predictors varied with scale, indicating that spatial scale matters in detecting habitat selection processes.
Our data provides evidence that habitat selection processes occurred at a small scale within the landscape; mammal diversity increased with forest cover recovery, though both positive and negative specific responses to patch structure were detected.
When the watershed analysis process was used in the Whitefish Mountains of northwest Montana, natural resource professionals were able to determine the dominant habitat forming processes important for native fishes and use that information to prioritize, plan, and implement the appropriate restoration activities at the watershed scale.
Consumer-citizens should assist in valuing the services themselves, not by considering habitat and processes, but through willingness to pay for the results of regulation and support (freedom from flooding, products of agriculture etc), as embodied in the approaches outlined in the sections above on marketable benefits and financial costs.
Increasing declines in productivity (average number of fledglings raised per territorial pair) have recently been reported in the Spanish Pyrenees associated with habitat saturation processes [13], [14].
The association of pollution and disease may further increase extinction risk if it interacts with the effects of habitat saturation processes [13], [14], [17].
Conversely, AFS appear to be discouraging population expansion outside the Pyrenean Mountains and have been related to habitat saturation processes [16], which are triggering negative population effects such as reductions in productivity and changes in mating behaviour [14] [15].
