Question 11

A famous ecologist,Dan Jantzen,has proposed that temperate forests can have a few dominant tree species in high density because winter keeps the insect populations suppressed and they cannot build up to numbers to decimate all the tree seeds.Meanwhile,the tropical forest insect populations can increase until they have destroyed all seeds,because there is no winter to interrupt their population growth.Propose a test for this hypothesis.
