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 is that the yellow cedar decline may be caused by insect parasites, specifically the cedar bark beetle. This beetle is known to attack cedar trees; the beetle larvae eat the wood. There have been recorded instances of sustained beetle attacks overwhelming and killing yellow cedars, so this insect is a good candidate for the cause of the tree's decline.
A second hypothesis attributes the decline to brown bears. Bears sometimes claw at the cedars in order to eat the tree bark, which has a high sugar content. In fact, the cedar bark can contain as much sugar as the wild berries that are a staple of the bears' diet. Although the bears' clawing is unlikely to destroy trees by itself, their aggressive feeding habits may critically weaken enough trees to be responsible for the decline.
The third hypothesis states that gradual changes of climate may be to blame. Over the last hundred years, the patterns of seasonal as well as day-to-day temperatures have changed in northwestern North America. These changes have affected the root systems of the yellow cedar trees: the fine surface roots now start growing in the late winter rather than in the early spring. The change in the timing of root growth may have significant consequences. Growing roots are sensitive and are therefore likely to suffer damage from partial freezing on cold winter nights. This frozen root damage may be capable of undermining the health of the whole tree, eventually killing it.

The article and the lecture are both about the usage of carved stone balls found in Scotland. The author of the reading believes that there are three possibilities for the usage of these stone balls. however, the lecturer challenges the claims made by the writer.
To begin with, the author argues that these stone balls used as hunting or fighting weapons. The ancients used some hunting weapons such as arrow and the use of them are completely clear, however, there wasn't any evidence of the usage of these balls as a weapon, it's true that some of them have holes but the other one is completely in perfect shape and these holes maybe came from a crack.
secondly, the writer suggests that these stone were used as primitive weighing measurement tools, on opposit the lecturer rebuts this by mentioning that maybe they have the same size but they are totally different in their weights, they made from various type of stone for example sandstone and their density are different.
Finally, the author posits that they might use it as a social marker, but the lecture position is that it can't be true. some of the stone marked very simply but the other one marked complex. moreover, these stones didn't find in the grave and there were not found any bone that indicates they used as a social mark.
