Landscape Ecology

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

Land Use

Metapopulation theory

Fragmentation = Ecological degradation and vulnerability

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

These critters like patches

The Importance of EdgeEdge

“Corridor”

Gene flow Source-sink population action Filtering

16.2 Two species-area curves

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