Concept essentials
- Community must be linked to the correct ecological unit, method or species interaction.
- The evidence for community depends on measurable abundance, distribution, survival or resource patterns.
- Community is clearest when cause, ecological process and population outcome are kept distinct.
- Field or graph evidence for community needs biological interpretation, not values alone.
