Nodes, networks, and MUMs: preserving diversity at all scales

摘要: The present focus of practical conservation efforts is limited in scope. This narrowness results an inability to evaluate and manage phenomena that operate at large spatiotemporal scales. Whereas real ecological function a space-time mosaic across full hierarchy biological entities processes, current strategies address spectrum this complexity. Conservation typically static (time-limited), concentrates on the habitat content rather than landscape context protected areas, evaluates relatively homogeneous communities instead heterogeneous landscapes, directs attention particular species populations and/or aggregate statistic diversity. Insufficient has been given broad patterns processes natural relative abundance (native diversity). authors conceptual scheme not only within but also which each preserve exists. Nodes concentrated value exist all levels hierarchy. Integration these high-quality nodes into functional network possible through establishment system interconnected multiple-use modules (MUMs). MUM protects buffers important phenomena, while encouraging movement individuals, species, nutrients, energy, even patches space time. An example presented for southeastern USA (south Georgia-north Florida), uses riparian coastal corridors interconnect existing areas. will facilitate reintroduction preservation wide-ranging such as Florida panther, help reconcile species-level ecosystem-level approaches.
