Intertidal communities on the Atlantic and Pacific coasts of North America, when compared at a

Question

given latitude, differ in their species richness: Pacific-coast communities have more species.

One hypothesis to account for the difference is that there are too few effective predators (e.g.

seastars) on the Atlantic coast to suppress competitive-dominant prey species.

Design an experiment to test this specific hypothesis. (15 marks) [HINT – laws exist which punish

people for introducing potentially nasty predators to environments which lack them! Your

experiment cannot entail a form of future “intertidal genocide”

Answer 1

Is there really someone who thinks this question has a solution?  Even the initial assertions are questionable.
