In this set of materials, the reading passage states that populations of the yellow cedar in northwestern North America is declining and explains several hypotheses as possible reasons. However, the lecturer finds all the ideas skeptical and emphasizes that none of them is adequate and provides some evidence to refute them all.
First of all, the author of the passage claims that this decline may be caused by insect parasites. In contrast, the lecturer argues that healthy cedars are resistant to the cedar bark beetles because they are saturated with some chemical which are poisonous for bark beetles. Actually, those trees which were infected, were already damaged and lost their ability to protect themselves and would die anyway. So, the cedar bark beetle is not responsible.
Furthermore, it is mentioned in the reading passage that brown bears claw at the cedars in order to eat the tree bark, which has a high sugar content. On the contrary, the lecturer contends that bears are not in islands so the rate of death should be less but it is equal with other parts. Hence, we cannot consider bears as a possible reason.
Finally, the reading passage asserts that gradual changes of climate may be to blame. Conversely, the lecturer believes that cold weather is in higher elevations so we expect that the rate of death be more in these part but trees in lower elevations were more vulnerable. In fact, freezing weather is not what killing the yellow cedar trees.
