Examples

• Space has long been recognized as an important factor for ecological processes
• Island Biogeography
• Metapopulations
• Metacommunities
• Landscape genetics

Definition

• Processes that affect species distribution and dynamics, and how these play out across space

Scale

(Temporal or spatial)

Resolution and Extent:

• usually, large extent requires medium/low resolution
• small extent requires high resolution

Example:

• In hardwood forests of NE USA:
  • Least Flycatchers negatively influence the distribution of American Redstarts at 4-ha plot scale
    • This is due to Competition
  • Over a regional (landscape) scale, they are positively associated
    • Since they are using the same habitat

Types of Data

• Vector and Raster data

Landscape Ecology / land cover

Spatial Dependence (autocorrelation)
