question 56

Multiple Choice

Menge and colleagues performed experiments in which they exposed some populations of mussels to sea stars and excluded sea stars from other mussel populations. Suppose two populations of mussels are the same size prior to treatment, and after treatment there are 600 mussels in the treatment without sea stars and 200 mussels in the treatment with sea stars. Suppose further that the sea star population consists of 10 individuals. What is the per capita interaction strength of sea stars on mussels?

• A) ln (3/10)
• B) (ln 600)/(ln 200)
• C) ln (0.33/10)
• D) ln (0.33/200)
