Landscape Ecology

Explore the intricate web of relationships in landscape ecology through concepts such as island biogeography, metapopulations, and patch dynamics. Learn about the impacts of edge effects, corridors, and gene flow on ecosystems. Understand how human activities and natural disturbances influence fragmentation, habitat mosaic, and species-area effects in modern landscapes. Discover the significance of edge habitats and corridors in facilitating gene flow, population dynamics, and filtering processes.

  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
