Presentation Transcript

  1. Landscape Ecology

  2. - Island Biogeography • - Metapopulations & Metacommunities • Patch Dynamics • Edge Effects • Corridors • - Gene flow • - Source-sink population action • Filtering- Species Area Effects • SLoSS Landscape Ecology

  3. Land Use

  4. Metapopulation theory

  5. Fragmentation = Ecological degradation and vulnerability

  6. In the modern landscape, human activities are the most prevalent cause of fragmentation/edge- but, natural disturbances also create edge. Patchiness can be ecologically beneficial. Patchiness vs. Fragmentation- - >What is the landscape context?? >Habitat Mosaic

  7. These critters like patches

  8. The Importance of Edge

  9. “Corridor”

  10. Gene flow • Source-sink population action • Filtering

  11. 16.2 Two species-area curves

  12. GIS is used to examine the relationships among multiple kinds of information

  13. SLOSS

  14. Landscape Ecology

  15. - Island Biogeography • - Metapopulations & Metacommunities • Patch Dynamics • Edge Effects • Corridors • - Gene flow • - Source-sink population action • Filtering- Species Area Effects • SLoSS Landscape Ecology
