Biomes and Ecoregions:
Interactions between climate, plants, and soil

Interactions between climate, plants and soil

lead to broad regions (biomes)

might need smaller, more refined definition for study (ecoregions)

scale

  • distance and time
  • ecological studies are focused at particular scales
    • individual
    • population
    • community
    • ecosystem
  • techniques and approaches
  • cross-scale studies are an intellectual challenge

 

   

climate patterns

  • global
  • Oregon
  • east flowing winds and moisture
  • ocean currents - el Nino/la Nina
  • mountains
  • temperature/rain diagrams

 

Oregon

plant communities

  • water availability
  • temperature

 

   

soil types

as accumulation of climate impacts and plant activity

 

 

 

list of major biomes and gross characteristics

  • location on Earth
  • climate (altitude or latitude)
  • characteristic plant types
  • primary productivity
  • biodiversity
