The reading passage introduces three theories to explained the decrease in the population of the yellow cedar tree. Ironically, the professor believes that none of the theories are accurate. He offers three counter-arguments to domnstrate weaknesses of each presumption.
The first paragraph states that parasitic insects including cedar bark beetle attacks the tree and its larvae eat the wood. In contrast, the professor claims that beetles can not attack to helathy yello cedar trees, because they produce a powerful chemical that is noxous to the beetls. The beetle cannot attack the tree as far as it is helathy, and beetles invade them when it is infected or dead. therefore insects are not responsible for decline in this kind of trees. This directly contradicts the theory mentioned in the first paragraph.
The next part of the reading shifts the blame to the brown bear. The author believs that their agressive foraging behaviors can be a factor that weaken the trees and cause them to die. The professor rejects this assumprion by suggesting that bears feed only on some trees. There is an Island and a mainland and population of trees is reduced in both, while no bears lives in island. Hence if the bears were responsible for the decline, the trees on the island should not be reduced.
Finally, the last paragraph mentions that climate change, and more specificly root frost were cause of the decline in population in the yellow cedar tree. Once again the professor disproves the assumption made by the text and emphasizes that the text forgot an important fact which is many more trees die in higher elevation which the weather is cold than lower elevation which weather is cold, but in this case, its is the freezing may have weaken the trees root but it does not kill them.
