Focus shifts to collective properties
Ecosystem
Focus is on ecosystems
Landscape
Focus is on broad scale distribution of ecosystem types

Methods for Testing Hypothesis
Observation and Monitoring Natural Experiments Manipulative Field Experiments Manipulative Artificial Ecosystem Experiments Conceptual Modeling Mathematical Modeling
Benefits: multiple factors considered
Limitations: lack of controls, multiple factors considered
Observation and Monitoring
Benefits: naturally spatial and temporal scale
Limitations: lack of replication, lack of adequate controls, lucky data
Natural Experiments
Benefits: direct test of predictions, natural ecosystems
Limitations: altering natural system, sensitive to temporal scales, lack replication
Manipulative Field Experiments
