he Water Hyacinth is an invasive species that seems to be causing problems to local rivers and ponds. What are an invasive species you may be wondering? An invasive species is a species that is not native to a specific location and can cause damage to an ecosystem. The water hyacinth is a free-floating perennial plant that can grow to a height of 3 feet. The plants have a tendency to spread at a rapid pace and often times grow thick mats above the water. Under these mats, the plants have a thick root system. The water hyacinth is a very beautiful plant but it causes many problems. This plant, again, forms very thick mats on top of the water’s surface which if it covers the entire surface, it can cause oxygen depletions for fish and other animals under the mats and eventually kill the. They reproduce very quickly and tend …show more content…
It has been spotted in states such as California, Hawaii, Virgin Islands, New York, Kentucky, Tennessee, Missouri, possession of it is illegal in Texas. These plants seem to be causing many different problems. The plants affect both biotic and abiotic factors in local ecosystems. When the water hyacinth’s form thick mats, they are outcompeting the fishes for oxygen space. When the species covers the entire water surface, it blocks the fishes from receiving oxygen and they then die due to this. They reproduce very quickly and tend to block off rivers and streams which means it blocks off usable water resources which then makes the rivers and streams unusable. The government has been notified about this problem and is making an effort to get people to slow down the reproduction and keep the population to a minimum which is why it is illegal in some states. It is not said if the plant is poisonous so, native species who are being affected by this plant can make an effort to try and eat the plant or destroy it in any way possible so there's more chance of
Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.
Unable to handle their giant snakes, and unable to find new homes for them, some owners illegally release them into the wild. They are also an invasive species, which means that they are not constrained by natural factors as much as they were in their native habitat. Invasive species have the potential to harm their new environments. The release of Burmese pythons in South Florida is especially troublesome because the subtropical climate and the vast undisturbed habitats of the Everglades enable the species to thrive.
A plant with opposite leaves, white to dark gold flowers in the spring, and tiny red berries in the fall, emerge to be the Amur Bush Honeysuckle. The root of the Honeysuckle is from birds planting the seeds. Amur Bush Honeysuckle is an extremely invasive plant species that was brought over from Asia, to southern Ohio in the late 1950s, however, it is a non-native species (harvard.edu, 1997). This plant grows at rapid speeds with a large ability to reseed. When Honeysuckle is planted it tends to take over uncontrollably and decrease the growth of other species around it. Honeysuckle usually flourishes near water or roadways. In other words, Honeysuckle is very plentiful and invasive in some areas, but negatively impacts the environment, water quality, and other organisms.
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
Tropicalia is not only know as a form of music in Brazil but as a rebellion. Its theme of cultural non conformity was strengthened by the idea that Brazil had lost its way. Tropicalia took a stand against the social and musical hierarchy of Brazil. Though mainly known as a form of Brazilian pop music Tropicalia is deeply rooted in the political and cultural background of Brazil.
Invasive species do not only affect other species in their ecosystem, but also cost the United States more than one hundred and twenty million dollars each year in damages (“Cost” par. 2). Invasive species come in all different forms, and all have a negative impact on the environment. These species can come into a new area without being detected at first, but as time goes on their effects can soon be seen. Efforts are being made to prevent these invasive species from destroying fish population and habitat, but in order to be successful they need to be done on a much larger scale. In order to protect Wisconsin's waters, which are already infected with many invasive species that cause great damage to our bodies of water, more actions need to be taken. It is vital to remove all invasive species from Wisconsin’s waters because it will improve fish habitat, native fish population, and water quality.
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
The short story "The Chrysanthemums" gives insight into the life of its author. John Steinbeck was born on February 27, 1902, in Salinas, California. The locale of the story is of key resemblance to the Salinas in which Steinbeck was born and bread. "Salinas was a typical American small town, [differing] only in location and a few distinctive features" (McCarthy 3). The protagonist of this story, Elisa Allen, also resembles Steinbeck's first wife. "Steinbeck probably based the character of Elisa Allen on his own first wife, Carol Henning Steinbeck. Like Elisa, Carol was a woman of considerable talent and energy who wore 'masculine clothes' and was 'strong, large-boned' and 'handsome rather than pretty'" (Hughes 23). Similar to the time frame in which Steinbeck lived, the theme of the story comes across as being male dominant and the rustic setting allows us to visualize this.
“It has always seemed strange to me... the things we admire in men, kindness and generosity, openness, honesty, understanding and feeling, are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest, are the traits of success. And while men admire the quality of the first they love the produce of the second.” This quote was once said by an amazing author, who described the world’s society today so perfectly that one may forget that he had was describing his society in the early and mid-nineteenth hundreds. John Steinbeck is considered one of America’s greatest author of literature. Many of his work is still read today as required reading in most high schools and college literature classes throughout the United States. His most famous story that had outlived him was the Grapes of Wrath, which led to him receive the Nobel Prize in Literature and the Pulitzer Prize in 1940. Many of John Steinbeck told in a realistic view of life and how men lived in them. Steinbeck grew up in California's Salinas Valley, a diverse area with a rich history. His upbringing help shape his writing, which gave many of his works a sense of place. The Chrysanthemums is a short story a part of John Steinbeck collection of The Long Valley. In his short story, The Chrysanthemums, it deal with different problems in society; however, some problems stand out more than others. Many people have interpret the story into many different ways, but my interpretation of the story depicts the inequality of gender in society, the analysis of the character Elisa , and the symbolic meaning of the Chrysanthemums.
When people think of invasive species, they normally do not think of the human species, but why not? There is a large debate about whether or not humans are an invasive species. Before people debate whether or not the human race is an invasive species, they should know the definition of one. The legal definition of an invasive species in the United States is “an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health” (Zielinski). The International Union for Conservation of Nature, IUCN, defines an invasive species as “animals, plants or other organisms introduced by man into places outside their natural range of distribution, where they become established and disperse, generating a negative impact on the local ecosystem and species” (Zielinski).

Amaranth is an ancient super plant, native of Peru, and has been cultivated as a grain for thousands of years. Amaranth was a staple food of the Aztecs, and was used as an integral part of Aztec religious ceremonies. The cultivation of amaranth was banned by the Spanish conquistadors upon their conquest of the Aztec nation, crops were burned and its use forbidden.
Vascular plants sequestered large amounts of CO2 through photosynthesis when they first expanded across terrestrial environment, leading to glaciation. Evaluate the claim that a similar glaciation event occurred when the first plants colonized land. Be sure to consider weather or not photosynthesis by these new species alone caused glaciation.
Water pollution and pollution in general is a problem that people don’t like to deal with. Water pollution can cause so much damage to people and to the animals that live in that body of water. The laws that we have are doing what they need to but we need to monitor the water more closely because if we don’t catch the pollution when it happens it could have a disastrous impact on the environment. It could kill all of the plant and animal life that lives in the water. Some of the pollutions that occur are very hard to clean up and the Eco-system may never fully recover. To clean something up it takes a lot of hours and a lot of man power to get this mess taken care of. Water pollution could be the cause of some animals being endangered. The government needs to strongly enforce environmental policies in order to resolve the current problems that our facing our bodies of water.
Invasive alien species are disrupting and changing the normal ecological functions of biomes, ecosystems, and the biosphere as a whole (CBD, 2009). They are a threat to biodiversity and can cause damage to, or even eradicate native species which natural cycles and other organisms depend on. While disrupting energy flow, food chains, and shaking the structure of ecosystems to the core, invasive species create not only ecological, but also a whole host of social, economical, and health issues that affect the livelihood of almost every organism on earth, including humans (CBD, 2009).
