Based on the given materials, the article as well as the lecture discuss zebra mussels, which are native Eastern Europe shellfish though they are distributing in some regions of North America. The author states that increasing population of these animals in target area may pose viable threats. That being said, the lecturer provides several ideas to repudiate this claim.
Initially, the author says that no one can stop the zebra mussel's moving from Europe to America, which can be done by new canals, owing to the fact that these fish can reach the destination by both living in ballast water and attaching bottom of the ship. If this phenomenon continues, the fish will settle the whole North America. However, the lecturer explains that this cannot be true because decision makers, as the people who worry about this occurrence, have more knowledge in compared to past; They can solve this problem by some ways to stop ships carrying the mussels. For instance, the ships can rake a time to refill their ballast water with salty ocean water, in which no zebra mussel can survive.
Secondly, the writer proclaims that since zebra mussels have a high rate of reproduction, they can control the new habitat and have huge effects on it, beside existing no predators for them. Yet again, the speaker underscores that there are lots of local birds in Europe which change their habit and eat a lot of zebra mussels. So, it can be predicted that these predators, which can eat huge amounts of birds as their diet, reduce the reproduction rate of mussels in America.
The final point of contention between the reading and listening passage is decreasing total fish population in new habitat by mussels. The author thinks that having existed in North America, the zebra mussels compete with other fishes for food, owing to the fact that they are plankton eaters. On the other hand, the speaker explains that zebra mussels have both negative and positive impacts in their new habitat. They can generate some nutrients which can be eaten by fishes in near bottom of lakes. So, more amounts of bottom-fish eating, the higher population of fishes.
