Essay topics: Populations of the yellow cedar, a species of tree that is common in northwestern North America, have been steadily declining for more than a century now, since about 1880. Scientists have advanced several hypotheses to explain this decline.

In this set of materials, both the reading passage and the lecture deal with the decline of the number of the yellow cedar, which is a type of tree. Regarding this topic, the author asserts that there are three possible hypotheses to prove the decreasing of the yellow cedar. From the lecture, however, the lecturer contradicts the author’s point by saying that the three theories described in the passage are flawed and unconvincing.
First of all, according to the lecture, the theory that the cedar bark beetle plays a crucial role in the continuously reducing of the yellow cedar, is unreliable. The yellow cedar trees resistant from insects because they have powerful chemicals that are harmful to insects. Further, the beetle is able to damage the trees that are unhealthy, which will die without any influence of the beetle. This counters the author’s view point that the cedar bark beetle is one of the possible reason of the death of the many yellow trees.
Secondly, the lecturer goes on to say that he challenges the author’s claim that the brown bears, which usually diet the yellow tree bark, lead to the decline of the yellow tree. This is because if the main cause of the decline of the tree is the brown bears, it cannot explain that the number of the tree are dying in an island where there is no brown bear. It implies that the brown bear cannot play a vital role in the dying of the yellow cedar.
Lastly, the lecturer maintains that the climate changes cannot contribute to the decline of the yellow tree. It is less possible that trees are able to sustain in higher elevation where it is warm rather than lower elevation where it is warm. However, relatively more trees are dying in lower elevation. This rebuts the author’s argument that the yellow cedar trees are dying because the trees are not able to adapt the deviations of climate in northwestern North America.
