Landscape Ecology (Metapopulations (Source-sink metapopulations…

- - - - "Habitat" is species specific
      - Need to determine correct spatial scale
      - Species richness should only includes species w/ similar habitat
      - Matrix influences value of patches
- - - - Colonisation rate linked to distance
      - Equilibrium theory
  - - - Eg: temperature, humidity, predators, ground cover etc.
- - - - Disturbance hypothesis
      - Habitat diversity hypothesis
      - Random placement of individuals and species
      - Island biogeography
    - - Smaller genetic diversity
      - More prone to stochastic events
      - Demographic variability
        
        inbreeding
      - enviro stochasticity - conditions that influence growth rate
        
        fecundity
        
        survival
        
        dispersal
        
        growth rate
    - - didn't sample all spp.
      - not all species respond to patch sizes positively
    - - size may not represent habitat area
  - - - Convoluted and complex - high interraction and flow
      - Simple boundary - low flow
    - - Abiotic - light, ind, temp, humidity
      - Biotic - sp. composition, behaviour, interraction
    - - Abundance ( no difference)
      - No spillover
      - spillover
      - transitional / moderate spillover
      - negative
      - positive
- - - - Strip corridors - wide but animals make territories and settle
      - Line corridors - narrow but sometimes too narrow
- - - - Spatial variation (matrix of different mediums)
        
        Eg: complex matrices vs simple matrices affects species density
      - Spatial scale
      - Temporal Variation (change over time)
      - Temporal scale (the speed with which species move through the matrix)
        
        eg: harvesting of wheatfields timing effecting lizards
      - Adaptation (highly unlikely)
