...Invasive Species Invasive species ballast battle gets bigger Duluth News-Tribune (Duluth, MN), August 23, 2011 Researchers might have found a way to battle invasive species in the water. On August 23, 2011, researchers tested a new system to battle invasive species in the water of Indiana Harbor in Gary, Indiana. They would pump chemicals into the water and then neutralize it with a second chemical. However, this chemical would kill more than just the invasive species. They would release the chemicals into the water and it would kill the invasive species in the water. The chemical used to kill the invasive species in the water was called sodium hydroxide. Then carbon dioxide was the chemical released into the water...

...Invasive Species are becoming an increasingly populous threat in the United States of America, and the United States government is not applying enough regulations and policies to control the import and spread of these species. To successfully stop the spread of these species and reduce the amount of new invasive species the government must act. The key to stopping the spread of these invasive is rapid response to the issue. The government must apply new policies, because without the government acting against these invasive species or regulating the flow of species the problem will just continue to increase (Beric, 2015). The problem with invasive species are they are just what their names imply, invasive. The threat level to the United States...

...Invasive Species Are Endangering Wildlife Currently, there are about 16,306 species endangered, and some have already gone extinct. Famous creatures like orangutans, gorillas, and giant pandas are just some of the few species currently endangered. There are many reasons causing these species to become endangered, and invasive species are a major reason for these events. Although many invasions seem harmless, invasive species should not be overlooked because of the major, negative impacts they have on ecosystems. Invasive species are organisms that move into habitats which they are not native to, similar to a pioneer. Invasive species can affect the ecosystem that they are occupying in various ways. These effects can be different depending on the specie, but they all may cause damage to the ecosystem. For example, when a blackberry bush invades a habitat, it takes space in the ground under trees and plants and takes their water. An invasive eel, however, would have different impacts on the environment compared to a blackberry...

...UK invasive species top facts * Invasive non-native species are thought to be one of the biggest threats to global biodiversity, second only to habitat loss. * There are almost 2,000 established non-native species in Great Britain. * Invasive non-native species cost Great Britain around £1.7 billion annually. * Invasive species have been introduced to the United Kingdom from every continent in the world apart from Antarctica. What is an invasive species? An invasive species is a species which has been introduced to an area outside its natural range and can cause a multitude of ecological, economic and public health problems within the new habitat as its population grows. Invasive species may belong to any taxonomic group, with mammals, reptiles, birds, amphibians, plants, invertebrates, fish and viruses all having invasive populations around the world. The extinctions of numerous species around the world can be attributed to the negative effects of invasive species. When a species is taken out of its natural range and placed into a new habitat it is removed from its natural predators and any pathogens which help to control its population. Without these, population growth may become out of control and the invader can rapidly colonise its new habitat. The characteristics which enable an invasive species to outcompete native species include fast growth, a short life cycle and the ability to tolerate a wide range of habitat types and environmental conditions. Successful...

...Non-native Invasive Species What is an invasive species? An invasive species is an organism that has very few natural predators, competitors, parasites, or diseases. They also have high reproductive rates than any other species in an ecosystem. They also live longer as well. They are the hardest to get rid of because of their reproductive system. I’m taking these facts and finding those in the Hydrilla water plant. This plant is really high in reproduction, which makes them a non-native invasive species. The Hydrilla is one of the most invasive species ever to exist. They are found to be taking over waters that had populations of Eurasian in it. This plant also causes damage to waterways...

...determining whether it is ethical to subject invasive species to pain and reduce invasive species populations. The first major ethical issue to consider when deciding whether it is ethical to manipulate animal populations is, whether it is ethical to cull invasive species to protect threatened species. It is not ethical to cull invasive species to protect threatened species because all invasive species have lives that matter to them and humans should honor their right to live. Some might argue that according to Utilitarianism, it is acceptable to cull invasive species to protect...

...the fenced area has a higher diversity which indicates less competition between species. The lower value of the unfenced area indicates that invasive plants have decreased the ability for other plants to survive in that community. In the fenced community, the Simpson’s Index shows more diversity in comparison to the unfenced community. While the fenced area has greater species richness due to the number a species found it has a lower evenness than the unfenced community. Due to the decreased species richness in the unfenced community there is a higher dominance of species found there. This allows for the dominant species to spread and take over. This can be seen from how the fern takes over much of the understory floor. The Sorenson’s Index reveals some overlapping qualities between the two communities but not enough to consider them identical. Discussion...

...are mostly non-native species? Invasive species are species in and ecosystem that are not native to that specific ecosystem, they are risking us finacially, and they are a threat to human health and other native species around us. We dont need this kind of threat living so close to us, that is why we all should try to take care of the problems caused by invasive species. We need to take control of invasive species because they are costing the U.S. tons of money every year from the damages they caused. According to the Wisconsin DNR, invasive species are costing the government $137 million per year and the number...

...Biochemistry: Now that the invasive species have taken over they will begin to alter biochemical properties of the previous ecosystem influencing edaphic properties in particular: moisture, light and oxygen availability, and soil temperature (Windham 2001). Plant species can have various influences on soil structure and nutrient content and/or availability (Corbin and D'Antonio 2012). Invasive plants can change the substrate nutrient cycling, by adding to or taking away from the current normal levels of nutrients involved in microbial respiration or the nutrients needed by the native plants directly, be it sulfur, nitrogen, carbon, phosphorus or methane, of the previously established ecosystem. Invasion of nitrogen fixers are the most...

...The Asian Long Horned Beetle Introduction The sustained existence of our environment and ecosystem is quickly being diminished and depleted by invasive species. Invasive species can be thought of as non-native, or alien species to a specific ecosystem that immediately causes economic or environmental harm or even harm to human upon introduction (7). This is concerning not only to our well being, but also on a macro-spectrum, our environment. In time where global warming and industrialization are already challenging the preservation of the biodiversity of ecosystems, invasive species are becoming an increasing threat to environments and ecosystems. A species that has recently threatened and destructed many states including Massachusetts, New York, and Ohio, is known as the Asian Long-Horned Beetle. The Asian Long-Horned Beetle attacks many species of trees, including “poplars, maples, elms, and mulberries” and has a primary impact on street trees (5). Although the beetle is no bigger than an inch, it definitely packs a punch, causing massive and widespread destruction, which costs several hundreds of dollars to be spent per infestation. Background on the Asian Long-Horned Beetle The Asian Long-Horned Beetle is a native to Asia and was introduced to the United States in 1996 from “wood pallets and other wood packing material accompanying cargo shipments from Asia” (7). The Asian-Longhorned beetle is a tiny creature that is measured to be 1 to 1.5 inches in length and antennae...

...#2 By: Taylor Mollon Should humans resurrect extinct species through de-extinction science? In my opinion this depends on many things. Will the species be able to coincide with current species? Where will these species live? Can this species be a danger to another species whether it be us as humans or any other species? Will the species be able to adapt to our current world? Lastly will it be able to reproduce? If the species is unable to coincide with other species this could cause a problem for either itself or other species. This resurrected species must be able to eat and live around other species otherwise it won’t survive. As I will mention many times throughout this paper if the species can’t survive there is no point in resurrection, you will just be putting a helpless animal into its death once again. The species must have a place to live and not in a lab or preservation facility. If we resurrect a species, it will have to be able to learn and grow in the wild otherwise it will never be able to survive. At the same time, it must be given a chance to reproduce in some way. The question I then ask is how can we allow a species to train itself for the wild without risking its own fatality before reproducing? On top of this, I personally feel as though it is unethical to facilitate an animal as I believe they should be able to roam free in the wild. If the species being resurrected can cause harm to us or any other animal, it should...

...little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems. Biodiversity is important because it boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. There are five main threats to biodiversity that I can cover later on in this report are: 1. Invasive alien species 2. Climate change 3. Nutrient loading 4. Water pollution 5. Loss of habitat 6. Overexploitation In this report my goal is to explain what biodiversity is in detail in depth and explain how important it is to the world. Also, to outline if and how these threats pose a threat to humanity in the 21st century. How important is biodiversity? Biodiversity is important for all species' survival. We need a variety of habitats for all the different species because each species is adapted to a certain set of environmental conditions. All species depend on each other to survive, so if one becomes extinct another species that relies on it could go extinct as well. Individual traits can allow some species to adapt to environmental changes, but many species cannot adapt if their habitat and food chains are greatly altered....

...Lantana is a very invasive, poisonous species of plant that spreads very quickly. The scientific name for lantana is Lantana camara. Lantana originated from South America, Central America and Mexico, and was first introduced to Australia in 1841 in the Adelaide Botanic Gardens being brought to Australia as an ornamental plant. It quickly spread and became one of Australia’s worst weeds and a weed of national significance. This is why it is now illegal in all states and territories of Australia to buy or sell any variety of lantana. Although it was introduced for use as a fence for cattle because it could grow up to 5 metres, it failed because if cattle ate it they would die because lantana is poisonous to cows. According to research from the...

Non-native and pathways 3 4. Invasion Impacts 4 5. Management Strategies 5 6. Conclusion 5 ABSTRACT 1. INTRODUCTION Invasive species has been recently recognised as a major cause of biodiversity loss (Mack et al. 2000) and is thought to be responsible for over 20% of recently extinct vertebrate species (Reid and Miller, 1989). The introduction of the small Indian mongoose (Herpestes auropunctatus) to islands, greatly highlights the devastating effects an invasive top predator can have on an insular ecosystem (Courchamp et al, 2003). Since the late 1800s, Herpestes auropunctatus has been introduced to many places, such as the Hawaiian and Fijian Islands, in order to control rat problems on sugar fields. However, as the Indian mongoose have generalist feeding habits, they prey on non-target native species (Vilella, 1998) and as a result have been responsible for the...
