declining in populations of yellow cedar
The article states that scientists have several hypotheses to show the reasons which caused declining in populations of yellow cedar, a species of tree living in northwestern North America. However, the professor finds all the ideas dubious and presents some evidence to refute them all.
First, the reading claims that insect parasites are the cause of killing yellow cedar. The professor rejects this point by saying that healthy yellow cedar is much more resistant to insect infestation and also these kinds of trees have powerful chemicals which are poisonous to insects. In fact, just damaged or sick yellow cedars might have died from insects and battles.
Second, the reading holds the view that brown bears destroy cedar trees in order to eat them because of the high sugar content in yellow cedar trees. However, the professor says that the yellow cedar population has been declining all across the coast of North America, particularly in islands where there is no bear. Therefore, the bears cannot be responsible for this issue.
Third, the reading asserts that climate change may result in yellow cedar trees’ death. In contrast, the speaker dismisses this issue by saying the fact that much more trees than cedar ones are sensitive to frost damage and changing the temperature should have a negative effect on all the trees. He also mentions that some yellow cedar trees can survive in high elevations and cold temperatures, while many of them have died in warm places and in low elevations relatively.
