concern about zebra mussel travel from eastern europe to north america
The reading and the lecture are both about zebra mussel. This fish had spread out from Eastern Europe, where they originally lived, to North America, due to ships travelling between these two locations. The reading expressed the author concern regarding the surpass of zebra mussel in North America. The lecturer casts doubt on the claims made in the article. He believes that original animals of North America will adapt to this change.
First, the author assumes that it is hard to control numbers of zebra mussel in their new habitat. It is mentioned that they can attach to the bottom of the ships and can live in ballast water of it. The lecturer challenges this point. He contends that if ballast water was filled from ocean instead of fresh waters, they will cause zebra mussel to die.
Second, the author fears that numbers of zebra mussel will increase at rapid rate. The reason for this concern is that they won’t have predators in their new habitat. The lecturer on the other hand, posits that other animals such as birds will notice the appearance of new food source and will start exploiting it.
Finally, the author holds the view that zebra mussel will affect other plankton eating animals badly. For instance, this may lead to reduction in their numbers. Although this may seem correct, the lecturer thinks that zebra mussel has positive effect on other animals. He believes that zebra produces nutrition elements that bottom feeding fishes feed on.
