Document Summary
The scientific method: to investigate species relationships, experimental studies must be made in the lab and field. Involves: data collection, data to test a hypothesis, purposed question, hypothesis is an educated guess that is posed to answer a phenomenon, must be testable, based on lab or field studies. Interpretation of results: statistical analysis, display of results, feedback to test initial hypothesis. If the results are inconsistent with predictions, then a new hypothesis must be constructed. If the results are consistent with predictions, further hypotheses and predictions will be developed to expand the set of observations. Example 3: ecology of forest birds: macarthur studied ecology of five species of warblers in spruce forests in north. America: theory predicted two species with identical ecological requirements could not coexist indefinitely, studies found that warblers coexisted by feeding in different zones of. Phosphorus the same tree: warbler species maintained distinctive feeding zones which facilitates coexistence, prevented competition.
