The reading specifies that there are three hypotheses explaining the decline of the yellow cedar population in northwestern North America. However, the lecture casts doubt on these hypotheses and brings about three specific reasons to refute the hypotheses mentioned in the reading passage.
First, based on the first hypothesis, a kind of insect parasite named cedar bark beetle may cause the reduction in the population of the yellow cedar because the beetle larvae eat the tree’s wood. On the other hand, the lecture asserts that the yellow cedar has a protective sac, which is poisonous to the beetle. If the larvae eat the wood, they eat the sac and dies. So, beetle larvae cannot endanger the population of the yellow cedar.
Second, based on the second hypothesis, since brown bears eat the trees’ bark, their aggressive eating habit may lead to decrease in population of the yellow cedars. In contrast, the professor states that the reduction of the population happens in islands as well as main lands in northwestern America. So, had the aggressive eating habit of bears been the reason for the population's reduction, the decrease in the population would not have happened in islands since brown beers do not exist in the islands.
Third, based on the third hypothesis, the population's decrease may result from climate change since yellow cedar trees start growing in late winter instead of the early spring. However, the professor asserts that had freezing been the reason for the reduction of population, the yellow cedar population would have decreased more in the higher elevations, but the population of cedars reduces more in lower elevations, which shows that the yellow cedar is resistant to freezing.
