The purpose of this lab report is to see if the upsurges and the diminutions on the invasive species populace along with the inferences that modifications of the ecosystem as one. • Introduction Colonization of the Great Lakes by zebra along with quagga mussels has deeply impacted the Great Lakes ecosystem. Quagga mussels are improved modified to living in colder temperatures as well as peopling soft substrates than zebra mussels; therefore they are capable to live in profounder expanses of the Great Lakes. Quagga mussels are currently the central invasive mussel species in the Great Lakes (Zebra and quagga mussels, n.d.). • Hypothesis/ Predicted Outcome As you can see zebra along with quagga mussels are well-organized sieve feeders. By feeding on phytoplankton and also the infinitesimal …show more content…
zooplankton, they distract liveliness in addition to the nutrients that would be obtainable to big zooplankton and also their predators from the aquatic column to the lake bottommost. As additional biomass is detached from the aquatic column, aquatic clearness upsurges, advocating the development of bottommost dwelling nuisance algae like Cladophora, big mats of which wash up on coast in decomposing tufts after it expires.
• Methods In the lab report you can see that zebra along with quagga mussel years are very high than others. The distinct percolation proportions can be up to 12.4 liters per day. As you look at the chart phytoplankton are detached by the main consumers, the zooplankton are condensed along with the forging fish and predators that feed on those fish ( INVASIVE SPECIES, 2013). • Results/ Outcome Zebra along with quagga mussels look as if to promote the development of the bacteria answerable for type E botulism in addition to distillate the botulism contaminant. Zebra along with quagga mussels transfer pollutants from aquatic column in addition sediments into their tissues. Zebra along with quagga mussels connect to hard substrates, comprising aquatic intake edifices, triggering the edifices to become stopped up. This greatly upsurges upkeep costs for aquatic treatment as well as sway generation services (Zebra and quagga mussels,
n.d.). • Discussion/ Analysis Based on the information from the report we got information on zebra along with quagga mussel deliveries from research experts during the Great Lakes district. Information from all bases was in statistics per square meter at point positions. To get approximations of compactness over the Lakes as an unceasing surface, we joint the densities of zebra along with quagga mussels at each sample point.
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.
It’s important that Zebra Mussels are dealt with great care. Zebra Mussels get their food and energy from filtering water. Nearly a quart can be filtered by and adult Zebra Mussel (“Zebra Mussels,” 2013, para. 5). So if there was an infestation of Zebra Mussels in a lake they could filter a lo...
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.
Since no North American predator or combination of predators has been shown to significantly reduce zebra mussel numbers, such spread would most likely result in permanent establishment of zebra mussels in many North American waterways.
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).
When the manure is not handled correctly the nutrients are washed into tributaries of the bay. Often too much manure and fertilizer is applied and the excessive nutrients find their way into the bay. Even when precautions are taken to keep excessive nutrients out of the bay they seep into the groundwater and pollute the
A different scenario takes place when an alien species is transported to a new area. Although direct competition with similar species is still a problem, the new kid in the block may have no natural pests and diseases. Thus, large stands of monocultures can occur. It is generally accepted that one plant species will support 10 species of animals. If one species takes over 99% of a given habitat dozens if not hundreds of species are lost from that area and some populations are stressed enough that extinction is possible.
The parameters used in this research were: 29-33 years of data for P inputs, outputs, initial concentrations for each lake and the activity of zooplankton (Daphnia pulicaria) only in for the two upper lakes (Lake Mendota and Lake Monona).

The lakes which have small algae propagation are called oligotrophic lakes. Accordingly the lakes which have large algae propagation are called eutrophic lakes. There are many factors to determine the algae propagation in a lake such as temperature, light, depth, size of the lake and nutrients from the surrounding environment, etc. In fact the Great Lakes were all oligotrophic lakes before industrialization. The factors such a size, depth and climate would keep the lakes cool and clear for a long-term. There is only a small amount of fertilizer and organic matters decompose from forest areas in the lakes at that time. Due to reduction of vegetation and thermal pollution, the temperature of many tributaries of the lake has been increased. Other than that highly concentrated city and agriculture makes a lot of nutrients and organic matter, such as inorganic phosphorus detergents and fertilizers, flowing into the lake increased nutrient content. In fact the increasing nutrients stimulate the growth of green plants such as algae. The plant will decompose after death and decomposition process consumes dissolved oxygen in the water. As a result some fish will died from lack of oxygen and the green plants will experience a highly growth resulting in the cloudy water which means increasing eutrophication process. Lake Erie has the highest biomass yield mainly because it is the shallowest water, the highest temperature of the lake so that it is the first and most serious eutrophication lake of the Great Lakes. The other reason is that the development of agriculture and the city in the earlier period reached a higher level. About 1/3 of the population of the Great Lakes area lives in Lake Erie region. This leads to the highly higher flow of contaminants to Lake Erie than any other lakes. It is generally agreed that Lake Erie was dying In Canada and the United States. Water polluted warning signs are visible
The Maumee River was the main source of Toledo’s early economic success and is the largest watershed in The Great Lakes system. The Maumee River runs through the Midwest, filled with highly productive farmlands. Drainage tiles allow removal of water from the top of the soil, and creates swampland used for farmers. Drainage tiles also collect majority of the runoff and transports to rivers and streams. Creating wetlands are vital to the health of waterways. Wetlands filter, clean and store water, they are some of the most important ecosystems in the world. The global climate change also plays a big role in the recent algae blooms. High amounts of rainfall create runoff. Director of Ohio Sea Grant Dr. Jeffrey Reutter said, “Bloom is regulated by the amount of phosphorus entering the lake. A wet year means a worse bloom.” Algae blooms during the summer have become more frequent around the western end of Lake
Algae blooms can develop slowly and their effects can be long lasting. The toxicity continues to take its toll on marine life, long after the bloom has dispersed (Edwards, 2013). Algae blooms in the water can contaminate the food supply of marine life and humans, posing health hazards to both (Phlips et al., 2012). The blooms limit the amount of light that can penetrate down into the water; thus, cutting down oxygen levels needed to sustain plankton and sea grass (Phlips et al., 2015). The toxins released by the blooms pass through the gills of fish and lead to death by respiratory failure (Flaherty & Landsberg, 2011). Plankton, seagrass, and fish are not the only marine life affected by the toxic blooms. Larger animals, such as the Florida manatee, are harmed by these algae blooms. Manatees succumb to toxic poisoning from the algae blooms by ingesting seagrass that has been polluted with neurotoxins (Edwards, 2013). Also, coastal birds that feed on fish in algae bloom infested waters are exposed to deadly bacteria levels. It is evident how climate change issues are causing Florida temperatures and rainfall to rise, while spreading the harmful effects of algae blooms (Phlips et al., 2012). A solution must be found to rid the water of this extremely harmful
How does the growth of the Invasive Species Colocasia escuelenta (Elephant Ear) affect the growth of Water Tupelo (Nyssa aquatica) in Bluebonnet Swamp?
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.
