Summarize the points made in the lecture, being sure to explain how they challenge the specific theories presented in the reading passage.
The yellow crazy ant is one of the world's most destructive invasive species (species that are not native to an area but rather introduced to it).It has spread to many regions of Earth and caused great damage to native ecosystems. In recent decades, the crazy ant has invaded part of a unique palm forest on one of the Seychelles Islands off the coast of Africa. Some strategies are being considered to stop the ant from spreading farther and damaging the unique ecosystem of the palm forest. One of the strategies proposed to stop the ants is to use traps containing a low concentration of chemicals that are toxic to the ants. These ant traps have been successfully used in other locations, such as an island near Australia, where up to 99 percent of the invasive ant population has been killed by traps. Another strategy would be to cut down broad-leaved trees, which are the ants favorite habitat. Broad-leaved trees host a type of insect that provides food (a sugary substance)for the yellow crazy ants. The broad-leaved trees are not native to the palm forest; they were introduced there recently. Removing the trees would not damage the palm forest ecosystem, but it would reduce the extent of the habitat preferred by the invasive ants, which might reduce their population. Finally, it has been noted that ant populations are significantly denser near areas with human activity. Recently, a sharp increase in yellow crazy ants has been observed at one edge of the palm forest where a new visitor center was built, which suggests that more ants were transported to the area with construction material used for the center and that the ants have been eating food left behind by visitors there. Limiting human activity near the palm forest could help reduce ant populations.
Unfortunately, the suggestions you read about are unlikely to work in this case. First of all, using toxic and traps would cause some unintended harm. You see, these traps do not differentiate between the yellow, crazy ants and other native species of ants. That means that the native ants can be harmed by the traps the island near Australia you read about does not have any native ants. So no unintended harm was done there. But in the palm forest on the Seychelles islands, there are native ant species present that we want to protect. And these ants would certainly be killed by the toxic traps.
Second, cutting down broad lived trees might not solve the problem. You see yellow crazy ants can thrive in several different kinds of ha BI ta TS. Yes, they thrive in a habitat with broad lived trees. However, they also do well in ha BI ta TS like open areas with increased sunlight. The trouble is, if we cut down the broad leaves trees, we would create areas of increased sunlight inside the palm forest. So in other words, if we cut down broad le AV ed trees, we might destroy 1 type of habitat that the ants like, but we'll be creating a new habitat that is also very friendly to the yellow crazy ants. So we won't get rid of the ants that way.
Finally limiting human activity around the forest might slow down the end spread a little, but it might lead to a serious economic problem.
You see, the islands palm forest is the regions main tourist attraction, and the unique trees and animals that live in the palm forest attract not just tourists, but also scientists who conduct studies on the regions, rare species. In fact, tourism and visits from scientists are the most important sources of income for the local people. Therefore, trying to limit human presence around the forest would negatively affect the economy of the whole region. Summarize the points made in the lecture, being sure to explain how they cast doubt on the specific solutions proposed in the reading passage.
The main point of contention in the article and lecture is the methodology of dealing with the invasive and harmful ant species known as the yellow crazy ant. This particular type of ant was, at some point, artificially introduced the ecosystem of Seychelles Islands, and different procedures pertaining to the control of their population are discussed in the passage, which have doubts casted upon their effectiveness in achieving this desired goal by the lecturer.
Firstly, the potential usage of traps containing toxic chemicals that would limit the growth of yellow crazy ant in the Seychelles is introduced by the passage and the potency of this method is then reinforced by the inclusion of positive results attained from a similar procedure done in Australia in order to control the yellow crazy ants. However, the lecturer mentions the potential dangers of using these chemicals on other native ants in the Seychelles as the poison cannot differentiate between what species is native and which is invasive. Moreover, she proclaims the seemingly promising results from the chemical usage in Australia to be irrelevant, as no native type of ants exist in that particular habitat and thus fails address this concern.
Secondly, the writer provides the solution of systematically destroying a desired habitat of the yellow crazy ants, broad-leaved trees. Such trees contain sugary substances ideal for consumption and are therefore potential areas for cultivation of this invasive insect. Once again, the lecturer counters this method by mentioning another environment in which yellow crazy ants could thrive, open areas with sunlight. With this in mind, she believes cutting down trees to demolish potential living spaces might actually introduce new ones, thus rendering this solution ineffective.
Finally, a third way to deal with yellow crazy ants is given by the article: limiting human activity, which ahs shown to correlate to larger ant populations. In the lecture, a different stance is taken. As attraction of tourists and research scientists is the primary mean by which the islands sustain their economy, limiting human activities could potentially harm the primary source of income of the islanders, all in favor of insignificantly small advances towards ant population control.
