The impact of non-native species and invasive threats are one of the most serious threats that native amphibians are facing today. Many invasive species are able to adapt to their new environments quickly. They can often out-compete natives for food resources or they simply prey on the native species. Amphibian declines have become an increasing issue. While amphibian diversity is severely threatened by habitat destruction, the threat from non-native predation and competition is rapidly contributing to amphibian population declines (Ficetola et. al, 2007; Young et. al, 2001). Amphibians are threatening amphibians, and the threat from invasive species is a global issue. In Mexico and Central America this threat is just as real if not more so due to the tropical rich biodiversity. Many of the southern Central American countries boast some of the richest ecosystems in biodiversity in the world (Reid, 1993; Young et. al, 2001). American bullfrog (Rana catesbeinana) The American bullfrog (Rana catesbeinana), a member of the family Ranidae, or â€Å"true frogs† is threatening several habitats and native species in Central America. Native to North America, the American bullfrogs are found in freshwater habitats from Nova Scotia, Canada, throughout the eastern United States into Northern east Mexico. (see figure 1-1) Among the largest frogs in North America, they are easily distinguishable by their size. The bullfrog is a large amphibian that challenges native amphibians for food and habitat resources, but the bullfrog has a voracious appetite and will consume any prey that it fit into their mouths. They can grow to a length of eight inches and weight up to two pounds in their native habitats. In artificial market nurseries they... ...at attracts a collector. Unfortunately like many exotic pets, the owners soon lose interest and instead of doing the responsible things, by finding a suitable owner, they release them thinking that it’s an acceptable practice. Management and inspection of the plant nurseries and the pet trade is still poorly governed. While some countries are implementing policies and regulations on inspections and trades it is will continue to be a problem. Solutions must come from the international community. It must also include educating traders, collectors, inspectors as well as other stakeholders and the public. The small size of theses frogs coupled with the high procreation rate has made control of established colonies difficult to manage. Several countries that have been infested by this tree frog are doing live captures and then humanely euthanatizing individuals.

Globalization: Economics and World

By reading Skidelsky’s article, he demonstrated a great explanation about the globalization and the future strategy for the world. According to this article, Skid sky analyzed the past financial recession influence to the world and the current world’s major issues in the world. In the Skidelsky’s article, he provided main arguments about globalization development after the collapse in autumn 2008. Before he provided a solution for the recession, Skidesky illustrated the current order problems in the world with examples and scholar’s theories.According to analysis Keynes and related theories, pointing the main problems of globalization, he believed that the most likely fate for globalization is to cooperate and implement cooperative solutions, which will be a quantum leap in the world to solve multiple problems. According to Skidelsky’s statement, the cooperation is necessary, which only accrued among states with the same values. Under this statement , he stated that the cooperation would be a useful tool to reduce the conflicts between democracy and globalization, which stated that non-democracy is important for states.Skidelsky’s provided other two options for the world, including creating a world sovereign and a project of Pax Americana. By comparing with among those three options, related a theory applies and real examples, Skidelsky demonstrated that the cooperative is the main option for the world to recovery from the global financial crisis. In order to ensure his argument more convinced, he also analyzed the current economic world situation with two scenarios, disintegration and global compact, which are only relying on specific countries or groups.Therefore, to solve the recession issue to the world, the cooperative becomes necessary, because the world cannot cut the recession. In the cooperation theory, only the vital state can become democratic. Within the whole nation, stronger states should follow the rules t o assist the weaker states to boost their economy. Skidelsky used the project for a league of democracies, George Soros to prove that cooperative between states is important. In the non-democratic version of cooperation, China and Russia are the major examples in the world.Furthermore, he demonstrated the game theory and treaties, which depended on the self-interest, which becomes the main element to development cooperative in the worldwide. From my opinion, I believed that the cooperative is the main issue to solve the recession issue in the world. With the development of globalization, a stronger country should assist other country to boost on their economic development. There is no economic government in the world. All countries and states need to focus on their self-interest and use power of cooperative with other countries to recovery from the financial recession.The implement cooperative solution is to reform in the state by cooperating within the country and cooperating with other countries in the world. By making joint efforts, the recession will be cut and the globalization will be powerful. Therefore, Skidelsky’s about cooperative argument is advancing and significant. There new solution will assist the world transfer from political economy to cooperation economy and the global financial recession will be reducing.
