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 explain this decline One hypothesis i

Both the reading and the lecture are about the population decline of the yellow cedar trees in North America. While the author of the reading argues that the main reasons for this phenomenon can be insects attack, bears, and climate change, the professor disputes this. He states the main reason for the yellow cedar population reduction is still a mystery, and none of the reasons mentioned in the reading is adequate. The professor casts doubt on the points made in the reading by providing three controversial reasons.

In the reading passage, the author begins by saying that the insects' invasion, particularly the cedar bark beetle, is one reason contributing to the yellow cedar population decline. However, the professor disagrees with this idea. He asserts that healthy yellow cedar trees are very resistant to insects and parasites as their bark contains some chemical stuff that is toxic for the insects. Also, he says that damaged trees, which were found covered by insects, were already damaged and dead.

Furthermore, according to the reading passage, bears are another reason for this phenomenon since they damage the trees with their claws to eat their bark. On the other hand, the professor points out that bears can not be considered a cause of this decline, although they may damage the trees. He says that these trees' population has declined all over the coast of North America, even in places with no bears.

Finally, the author believes that climate change and its impact on the root system of these trees is another contributing factor. Not surprisingly, the professor refutes this assertion by contending that frost damage usually occurs in the highest elevation where the nights are frigid and freezing. However, the number of dead yellow cedar trees is much higher in lower elevations, where the climate is relatively warmer than the higher elevation, so this factor is not reasonable.

To sum up, both the writer and lecturer hold conflicting views on the reasons for the yellow cedar population reduction.
