Document Summary
Evenness: relative distribution of species in the community - opposite of dominance. Spatial diversity: vertical (light management, canopy) and horizontal structure (overall more ecological niches open up and are created) Temporal diversity: degree of cyclical changes; crop rotations. Structural diversity: number of locations (niches and trophic levels) and connections between trophic groups. Functional diversity: ecological processes (nutrient cycling, energy flow, biological control) Alpha diversity is just the diversity of each site (local species pool). Beta diversity represents the differences in species composition among sites. Looks at proportion of yield in poly vs. mono and adds them up. Take partial ler for each crop (just ler formula for crop a, and ler for. Then add up partial lers to get ler (over 1) Crop a partial ler = . 83, crop b partial ler = . 80 so ler = . 83 + Looked at how ecosystems/# of species reacted to this disturbance. Where your immigration = extinction equilibrium in # of species.
