to combine the forms of study

3

Interacting components are...

biotic and abiotic

4

ecological organization

Individual
Population
Community
Ecosystem
Landscape
Region/Biome
Biosphere

5

Focus is on an individual

Individual

6

Focus is on a single species

Population

7

Focus in on more than one species

Community

8

Focus shifts to collective properties

Ecosystem

9

Focus is on ecosystems

Landscape

10

Focus is on broad scale distribution of ecosystem types

Region/Biome

11

Focus is on links between ecosystems and other components of the Earth system

Biosphere

12

Methods for Testing Hypothesis

Observation and Monitoring
Natural Experiments
Manipulative Field Experiments
Manipulative Artificial Ecosystem Experiments
Conceptual Modeling
Mathematical Modeling

13

Benefits: multiple factors considered
Limitations: lack of controls, multiple factors considered

Observation and Monitoring

14

Benefits: naturally spatial and temporal scale
Limitations: lack of replication, lack of adequate controls, lucky data

Natural Experiments

15

Benefits: direct test of predictions, natural ecosystems
Limitations: altering natural system, sensitive to temporal scales, lack replication

Manipulative Field Experiments

16

Benefits: tests magnitude of predictions, very well controlled, high replication
Limitations: ecological context limited, understanding temporal and spatial scales limited

Manipulative Artificial Ecosystem Experiments

17

Benefits: provides testable qualitative predictions
Limitations: reduces complexity, not real ecosystems, is qualitative not quantitative

Conceptual Modeling

18

Benefits: provides quantitative predictions
Limitations: reduces complexity, not real system

Mathematical Modeling

19

Temporal Scale

Time

20

Spatial Scale

Geographic space

21

context dependent conclusions

spatial scale and temporal scale
