The reading and the lecture are both about zebra mussels invasion in North America . The reading states that stopping the invasion of the zebra mussels is impossible. The lecturer cast doubt about the points made in the reading by saying that zebra mussels could not have been controlled in the past because we lake knowledge of ways to stop the invasion. The lecturer provides three reasons.
Firstly, the reading states that the zebra mussels spread was made possible by the ships that traveled from Europe to North America. Because the mussels can attach themselves to the ship’s bottom or can survive in the ballast water of the ship. The lecturer suggests that the ships can easily get rid of the zebra mussels by emptying the water and replacing it with new salty water from the ocean that will help kill the mussels before arriving to the destination.
Secondly, the reading states that zebra mussels, once carried to the new habitat, they become dominants since they do not have predators. In addition, species with no predators are likely to dominate their habitat. The lecturer disputes this point. He mentions that they might not have predators at the beginning but sooner other species will notice them and eat them. Furthermore, he gives the example of birds who started to eat the zebra mussels when they noticed their existence.
Lastly, the reading suggests that zebra mussels are likely to cause a decline in the overall fish population since they are plankton eaters like fish. As a result they would compete for food. The lecturer refutes this point by says that zebra mussel does not only have a negative effect on the fish they compete for food with, but they can also have a positive effect. He mentions that zebra mussels can generate nutriments that can be eaten by fish. As a results zebra mussels can live in a harmony with other fish without harming their population.
In conclusion, although the reading and the lecture are both about the zebra mussels invasion, the three main points made in the reading effectively challenged the lecturer.
