The name of my species is Hydrilla. The scientific name of this species is Esthwaite Waterweed. The classification is Alismatales because all plants that fall there is either aquatic or tropical. Hydrilla has really impacted our world. The Hydrilla plant may be "good" to goldfish, for the reason that they play with it, yet it can ruin anybody's life. It was brought from another country, but it really impacted people's lives and the ecosystems. Although Hydrilla was originally from warmer parts of Asia, it has spread in some parts of North America. The Hydrilla was found in Florida in 1960 due to the aquarium trade. It impacted our lives and other organisms lives because of the scarce vegetation. In the ecosystem, the hydrilla would kill many …show more content…
According to ebooks- lab aids, "Hydrilla verticillata, as it is known scientifically, can clog up city water intake valves and get tangled in boat propellers. 'We used to have the best swimming hole down by the bridge,' said Rita Aziz, a 7th grader at Junior Middle School. 'Now it’s filled with this gross weed. The last time I swam there, I got tangled in it. It was scary. I would really like to find a way to do something about it.'". The Hydrilla didn't help their own case by clogging up city water intake. The impact or issues that hydrilla had caused are that the mats are so dense they alter water quality by raising pH levels, decreasing oxygen under mats and increasing water temperatures. It can grow very fast. It can slow down water flow 85%. It covers up plants that make oxygen for fish which kills the fish. It covers. under native plants and pushes them up and out of their place. But even then, the Hydrilla has succeeded to kill other vegetation and other organisms. Even though hydrilla was eliminated in one place it would affect another
Elodea also known as Elodea canadensis is a genus of aquatic plants. They are also called waterweeds and is mainly used in aquarium vegetation. It plays a significant role in aquatic vegetation as it produces a significant amount of carbon dioxide under the perfect conditions. Elodea mainly grows in shallow water and can also be sometimes found in deep water. The plant for this experiment is kept in a water tank. We use elodea for this experiment as this is a very good plant that play a crucial part in our experiment. The amount of carbon dioxide produced by the plant during the experiment can be used to understand the rate of the reaction.
As if there weren’t enough problems for scientists trying to save the Great Lakes Eco System. Many non-native species have entered the eco system and many of them are harmful. Every species in itself has played a role in the eco system. These non-native species make it increasingly difficult for the Great Lakes Eco System to be regulated.
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.
This vegetation also provides much cover for fish. The aquatic plants provide a great source of food supply and act as a nursery for young fish (“Native” par. 5). Vegetation serves many purposes in fish habitat; besides keeping fish safe. It also helps keep the lakes clean. Aquatic plants cycle the water and help absorb pollutants. Another great benefit of these aquatic plants are that they help hold sediment and the banks of the lakes in place while providing oxygen into the water (“Invasive” par. 7-8). Unfortunately invasive species are destroying such vegetation. The Common Carp or “Cyprinus carpio” is one such fish that is causing great damages to lakes all around the world.
The Chesapeake Bay plays host to an astonishing amount of plant and animal life, providing much of our fish intake for species that aren’t being overfished. For the species that are being overdrawn, the Chesapeake Bay Foundation is working to restore the populations, and it’s going well thus far. Another theme that is endangering the marine life populations as well as the health of the human population is the massive amount of polluti...
Eurasian milfoil or Myriophyllum spicatum is an aquatic invasive plant that can be found throughout the Chicagoland area and in surrounding bodies of water. This plant can be a hindrance to swimming, boating, and fishing because of their thick, tangled stems and mats of vegetation. According to the Minnesota Sea Grant, Eurasian milfoil also overcrowd a body of water, which leaves little room for the plants native to the Great Lakes. One prediction is that if the Eurasian milfoil is not stopped, a reduction of biodiversity may result in Chicago and the areas surrounding it. If this was to occur, the ecosystems of the Midwest region would be significantly impacted in a negative way.
Hypatia was a famous Neoplatonist philosopher from Alexandria Egypt. Her father was Theon a well-known mathematician and astronomer that are mostly known for the invention of the astrolabe and artifact used to measure the altitude of a planet or star. Hypatia was following the steps of her father until she decided to travel to Rome and Greece to work on her post graduate carrier. She was well known around the Mediterranean for her brains and beauty.
The Chesapeake Bay has faced an excessive amount of pollution over the past century. The water in the bay has become so highly polluted that It is capable of causing harm to humans coming in direct contact with the water. Although algae serves a vital role in the bay’s ecosystem, it also creates a problem that is causing a large amount of the problem.
By carelessly shifting around organisms, with their awesome genetic potential, we have caused major ecological disasters. Gone is the most important tree in the Northeast, the American Chestnut, our premier landscaping tree, the American Elm, and gone are huge tracts of productive fresh water marsh. Now these marshes contain only monocultures (only one species present) of purple loosestrife.
Invasive species, (also known as invasive alien species or simply alien species) are defined as any organism (plant, animal, pathogen, or other living thing) that is alien (non-native) to an ecosystem, which can cause adverse economical, ecological, or health effects to native species and/or humans. The roots of these problems all stem from the massive negative ecological impact these organisms are having on the environment (CBD, 2009). For all animal extinctions where the cause is known since the 1600’s, invasive alien species have been a contributing factor 40% of the time (CBD, 2006); the second most contributing factor to extinctions after loss of habitat (GC, 2013). By eliminating native species through competition for resources, predation, and transmittal of disease, invasive species continue to reduce biodiversity in almost all ecosystems around the world (CBD, 2009). In the future, this problem may worsen, and if no action is taken, could lead to a cascading ecological problem so large that whole communities or even ecosystems could collapse.
Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
To quote Hypatia, “Life is an unfoldment, and the further we travel the more truth we can comprehend. To understand the things that are at our door is the best preparation for understanding those that lie beyond” (BrainyQuote, 2013). April of 2012, I recall my niece who was then 16 years of age called me to ask for advices. She was growing fast, assertive on what she wanted to be and about her future goals. However she had a very serious problem. That kind of problem that almost every teenager is faced with. “Why is that all of my friends they criticize me for not doing what the do” she asked; and why is that every want me to be like them, and don’t want to let me be myself she followed. Few second of thinking, and I recalled a movie I watched couple months ago, titled “Agora”. It was a movie based on the life of Hypatia. She was a female mathematician and philosopher who lived and died upholding the principles. On this post, I will review the life of Hypatia noting her life stages in as they relate to cognitive, physical, and social-emotional developmental processes.
Hypatia was born in the year 370 AD in Alexandria, Egypt. She was the daughter of Theon, a famous mathematician and astronomer. He invented many things, but his most famous invention is the astrolabe, which measures the altitude of a star or planet. Hypatia studied with her father for many years at the Museum in Alexandria, but soon became unsatisfied with his instruction because she was smarter than him. She left Egypt, and traveled to Greece and Rome to do "post-graduate" work. Her brains and beauty gave her a wonderful reputation throughout the capitols near the Mediterranean.
The oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. When dangerous substances go into the ocean, ecosystems are suffer and become endangered along with lives of people and of marine life. Surfrider Foundation recognizes the importance of protecting and preserving the quality and biodiversity of the world's coasts because they are truly irreplaceable. There is also historical evidence of ocean pollution being present in the past, but the problem still lingers today. Heal the Bay discovered that,“Did you know there is a DDT and PCB hot spot off the coast of Palos Verdes? This superfund site (which indicates it's one of the most polluted places in the United States), is left over from a 1930's era chemical plant. Because DDT takes so long to break down in the marine environment, it persists to this day, contaminating certain species of fish. There are also highly polluted sediments in the Long Beach area, a sign of the heavy shipping in the port. Heal the Bay works on developing effective capping and removal plans to keep those toxins from spreading” (Heal the Bay). DDT is still highly concentrated in the South Bay area and still contaminating different species of fish. Even after more than 80 years DDT, a toxic insecticide, is still very concentrated and during upwellings, DDT particles come back up and continue to harm marine life. If humans are careless about what is thrown on the floor or sprayed on lawns, it can lead to disastrous affects when it comes to the condition of the ocean's ecosystems, and can endanger life itself leading to a problem that only we can mend.
Seagrass is on the decline around the world and it is an extremely vital marine ecosystem found in shallow water mainly distributed throughout tropical seas, from a temperature around 4oC to 24oC (Green and Short 2003). They are the only true flowering plant (angiosperm) to live in aquatic conditions providing support and shelter for vast amounts of species (Orth et al. 2006; Jackson et al. 2001). They are a marine aquatic plant and a keystone species for many coastal areas found all over the world (Libralato, Christensen and Pauly 2006). Although there is not a huge variety of species, there are only around 60 species globally and over 14% of them are endangered (Green and Short 2003; Orth et al. 2006). The different seagrass ecosystems perform relatively similarly throughout the varying species (Turner and Schwarz 2006). This study will examine the various importances of seagrass and to what extent they are vital for the survival of species within their ecosystem. In addition to this, the role of seagrass in important ecosystem processes will be examined. The abundance of coastal regions are closely linked with seagrasses as they greatly contribute to productivity. Seagrass meadows are highly productive and are ideal for nurseries and providing a relatively safe habitat and shelter from predators (Hughes et al. (2008).
