Landscape Ecology

  1. 1. Landscape Ecology Bitangcor, Cindy Cayasan, Roxanne Manan,
  2. 2. •A marriage of ecology and geography.•Studies how differences and changes in landscape affects biota and ecology.•How they affect distribution, energy flow, survival, reproduction, recruitment, etc.•Assesses how habitat integrity, patchiness, fragmentation, connectivity, etc. affect
  3. 3. • Landscape ecology emphasizes heterogeneity as a method to promote stability in an ecosystem. Heterogeneity increases types of resistances to catastrophes through genetic diversity, habitat diversity, and strain of species distribution.• Landscape ecology always understands that systems change
  4. 4. Definition of Terms 1. Landscape: an area that consists of more than one ecosystem. 2. Ecosystem: A group of various populations in one area and their interactions among each other and with their environment 3. Heterogeneity: A landscape with many different ecological patterns and structures. 4. Pattern: The ordered contents of a
  5. 5. 7. Patch: A homogeneous area different to other areas around it. A patch is the lowest ranked unit of a landscape.8. Mosaic: is a series of patches connected together directly or via corridors.9. Corridor: A particular kind of patch connecting two separate patches.10.Edge: In ecology, an edge is the
  6. 6. 10.Types of boundaries: 1. Ecotone: Transitional zone between two communities. 2. Ecocline: The lines of different communities that exist within an ecotone. 3. Ecotope: similar area in an ecotone. They might be distinct and relatively far spaced but have similar characteristics and thus life structure.11.Disturbance: an event that alters the process of change or stability of
  7. 7. Tools of Landscape Ecology Models: a model is an abstract representation of a particular system, process, or occurrence. The models in this field can be physical, verbal, or mathematical. The most complicated and perhaps most useful to landscape ecologists are mathematical models that are based on complex formulas. In order to simplify very complex systems of relationships, mathematical models predict and explain patterns and phenomena. Remote Sensing: Very simply remote
  8. 8. • Geographic Information Systems (Gis): GIS uses software to compare layers of spatial information and can run analysis on patterns and other data. Often the information gathered from remote sensing
