What study is written about in this article?
Give details ( 100-200 words)
This article is about the great expansion and overpopulation that is occurring in the species called Pterois volitans commonly called lionfish, and how despite technological breakthroughs have today, cannot yet be able to identify the causes and why a species that invades habitats completely different as is the case of the deep atlantics. A grows this lionfish population; the main species affected are the other smaller and less helpless. The lionfish is a deadly fish with high toxicity, as has the ability to eat very large prey, today lionfish has no predators, no one else but the human being, and as this can use this fish as one of the finest delicacies. In addition to this also talks about the hypothesis that lionfish are protecting yourself from human predators in the depths, because, today is still very difficult to make catches in deep water. One hypothesis that has not yet been confirmed nor experienced.
What is the aim of this article? Research?
The main objective of this article is to inform. Comment hypotheses and studies carried out by scientist Stephanie Green, and as these provide more detail to the whole of research being done. These studies need much longer than experimental basis of persistence and perseverance. Generally is reported as the investigations that have been conducted have served to rise the hypothesis that today remains on the invasion of lionfish in deep water. And as the experience and theory go hand in hand, as the hypothesis that lionfish is hiding in deep water of human beings, it is purely experimental, but with much study based on different theories.
What is the author’s position?
The author's position is a critical position, a position to report on the ongoing efforts by the scientific Stephanie Green on the lionfish invasion. This author does not give his point of view, or any comments about it. This author basically talks about the studies and evidence were found in the depths of the lionfish invasion and it’s dangerous. It focuses solely on reporting. Demonstrate and be consistent in the face of research, data and references clear and concise.
What conclusions does the article make?
(100-300 words)
The conclusion of this article focuses on the future. In hypothesizing that achieve solutions become lionfish invasion in the Atlantic, imposing scientific method such as deep water gripes, which capture large species, which could become a very good solution to this great invasion although it could affect the marine ecosystem, which would be affected by the change in pH in the water, moreover, that in these networks traps, will be involved not only the species of lionfish, but on the contrary, many endemic species. Risks should be taken to curb and stop this invasion that we are indirectly affected us too, as the diversity and population of marine species is declining quickly and with no explanation why. The toxicity presenting peace lion is high, and the mortality is equally high. Factors that is not favourable for the development and sustainability in a healthy marine environment. Future experiments, based on the present expeditions. New theories, new ideas and new hypotheses about this but as flashy as deadly lionfish. Which from the beginning had no explanation of why it’s easy adaptation to different marine ecosystems, regardless of temperature, depth,
