Ecology

Q: "Simpson Index" can be loosely applied to 3 different values (and calculations) depending on the author/source: Simpson's Index, Simpson's Index of Diversity and Simpson's Reciprocal Index. This should be clarified. (section: 3/ paragraph:  b/ sub-paragraph:  iv/ line: 2)

A: Students should be familiar with all three. If used for the National competition the national supervisor will specify which is being used. We have chosen to define the Simpson index, p as the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), Σ is still the sum of the calculations, and s is the number of species. This information can be found on the files distributed at coaches clinics and will also be on the SO website once the clinics are over.

Q:  Could you clarify what aspects "local and regional ecology" refers to, mainly, how will general ecological principles be applied to specific regions? (section: 3/ paragraph:  a/ sub-paragraph:  i/ line: 5)

A: Thank you for your question. Unfortunately, questions regarding what will be covered on a test or how to coach the event will not be answered.

Q: The rules state that the ecology test will be divided into 3 sections. Will these sections be separated and labeled as Parts 1-3? Or will the types of questions be integrated throughout the test? (section: 3/ paragraph:  / sub-paragraph:  / line: 1)

A: Thank you for your question. Unfortunately, questions regarding what will be covered on a test, the format of the test, or how to coach the event will not be answered.
