- macro pattern governing biome dynamics
- it is the invisible hand define by
- temperature: average, range, seasonal
- precipitation: amount, rhythm
- humidity: water in air
- sun: exposure, angle, duration
- wind: direction, intensity, flow pattern
- the key to climate, is microclimate
- sunlight exposure: south-facing vs north-facing slopes
- wind protection: behind a hedge vs in open field
- moisture: near a pond vs on a rocky slope
- thermal mass: near stone wall vs open air
- canopy cover: shade vs full sun
