Resources: Field Study by Beren Robinson in Ch. 5 of Elements of EcologyWrite a 700- to 1,050-word paper explaining the important aspects of the study and how they relate to ecology and evolution.Describe original observations of researchers.Describe the study in detail:
• Research questions of study• Hypotheses• Variables in study
Discuss research findings.
• Include a brief, general overview of how ecologists use evidence and observation to quantify results before going in to the specific findings of this case study.
Discuss evolution and its relationship to natural selection.
• What role do they play in ecology?• What role do they play specifically in the case study chosen?
Propose a follow-up study based on the case study. Briefly address the following questions:
• What variables would you alter?• What additional findings might you expect to discover on aspects of evolution or natural selection in your proposed study?
Suppose that a new low calorie sweetener is developed. The structure is novel and is tested with the Ames test for mutagenicity.
