Abiotic Factors Of The Pond As A Seed And Nutrient Trap

Factors that may have affected the accuracy of the readings, may have been that the observations and recordings of all abiotic data was collected from one area rather than multiple sites within the area. The students involved in data collection, had no previous experience in the use of certain equipment such as the soil thermometer and refractometer, therefore, results may have varied significantly due to inadequate/improper use of equipment.

The first station we had was counting crustaceans and macroinvertebrates in the water. We found 113 critters that belonged in group 1 which means it is quality water. There were 2 organisms in group 2 which was somewhat quality water. Also, 16 critters in group 3 which means the water is very polluted. Overall, based on the critter

Therefore some suggestions for improvement in future test include: conducting tests whilst setting controls such as time of the day and condition over a period of time to get the most accurate answers possible. Eg. Dissolved oxygen rates can vary over the period of the day. Another improvement would be following the methodology more strictly to reduce any margin for error, clearly apparent in our phosphate test. But despite our best efforts, there were some events that could not be avoided such as an oil spill in the creek that would have impacted on the macro-invertebrates results we tested after this

Paradise pond is a well known trademark of Smith college. Having been in place long before Smith College was founded, it has always served as a breathtaking release from the realities of our world. However, Paradise Pond also serves an important ecological factor in supporting its own diverse community of organism. Unfortunately, keeping Paradise Pond together is a dam. Typically, rivers have a consistent flow of water that allows the sediment to evenly flow throughout a space; however, due to the dam, Paradise Pond is filling with sediment.

The Deciduous Bottomland Complex is made up of bottomland containing silver maple and bur oak that are resistant to heavy floods, river levee containing basswood and hackberry forests, bur aak, and American elm, and marshes located in the Bottomland Complex that contain cattails and bur-reed. The Glacial Lake Shoreline is made up of deciduous forest of the Nippissing Bluff containing beech, white birch, and sugar maple, which is the most important, and gently sloping Lake Payette Terrace containing cedar or balsam fir forests where scattered pools are present. These different complexes all help with flooding and erosion. The roots of these plants stabilize the soil preventing erosion. Also, the presence of the plants affects the hydrology of the water. This includes the water level, water flow, and water chemistry. The velocity of the water flowing through the Swamp determines how much erosion occurs for the water cutting into the soil, but with trees and other different plants present the water is slowed reducing erosion. The chemistry of the water is influenced by the plants by seeing how much nutrients is present, or what kind of elements appear in the water due to the plant. The major prevention of flooding is due to the

Overall the objective of this lab exercise was to introduce students to watershed ecology and the ecological factors that affect water quality. Students used biotic (macroinvertebrates ) and abiotic indicators to asses the quality of water in a freshwater body. Specifically students collected water chemistry data (hardness, nitrate/phosphate concentrations, dissolved O2 and pH) to asses the quality of water. Additionally macroinvertebrates from the benthic environment of a respective field site were collected, analyzed as well as catalogued. Collectively the results indicated that a greater species diversity was indicative of greater water quality(Lenat). Likewise within a freshwater ecosystems a negative correlation was found to exist between fluctuating abiotic factors,species diversity and water quality. It can be concluded that amongst the three field sites the ranking of water quality from highest to lowest is as follows; Great Brook Farm, Russell Mill pond, Lawrence Street Stream.

Over the generations, especially in this day and age, ecological problems have become top priority whether it’s to presidential debates or the uprising of the environmentalists who stayed quiet for far too long. It doesn’t have to be a large national park, but observing a not-so-well-known creek like Newtown Creek, represents the sludge and poison industrialism and the human race itself has force-fed nature. Seeing a desolated creek will make anyone think twice before throwing even a gum wrapper onto the streets instead of the trash can two feet away.

The question being investigated is, what is the water quality of the UHigh creek based on invertebrates found in the water? The water quality is determined by the dissolved oxygen, the pH level, the nitrogen levels, and phosphorous level. The dissolved oxygen is the amount of oxygen molecules mixed in with the water molecules. If the dissolved oxygen level is low, then the water will become polluted. Dissolved oxygen range is 1-14 parts per million or milligrams per liter(Riverwatch). The aquatic organisms need these dissolved oxygen molecules to breathe and survive. Another factor for measuring water quality is the pH levels. This measures the acidity of different solutions in the water. A pH range of 6.5-8.5 is considered safe for aquatic life. Another factor for measuring water quality is nitrogen. It is found as ammonia and the content of nitrogen in the water should be no more than 1.3-2.2 mg/L. If it is above this range it can

Centennial Park has the largest freshwater wetland system in inner metropolitan area of Sydney. Its ponds cover approximately 26 ha of area connected in a water flow system that acts as detention basin for stormwater drainage during flood events (Centennial Parklands, ponds, 2016). Moreover, these ponds provided the water as the Sydney’s main source of drinking water from 1837. The park provides an open area for families and kids to enjoy picnics and therefore the pond is required to maintain its water quality and sustainable for the environment.

However our overall results do not completely account for the differences in pH we saw due to the lack of measurements of phosphate in the Bear Creek analysis. This would further be exasperated by any mistakes made in the measurements of oxygen and ammonia.It should also be noted that we also had to account for the fact that it was summer and thus much hotter than what we would normally expect; thus if a higher temperature in conjunction with other factors discourages or incourages bioindicators we would have no way knowing since we cannot create a control for the

In the littoral zone three groups collected data on water temperature, pH, water depth and biota.

Planting on riparian areas promote bank stabilization and water quality protections. The roots of riparian trees and shrubs help stream banks to be held in place, preventing excessive erosion. The vegetation also traps sediment and pollutants, keeping the water cleaner. Streams and rivers are also protected

For this lab, we decided to focus on specific parameter values in order to compare the water samples from one another. We began testing out the temperature of the waters, for little lake pond (groundwater) we found that the temperature was at 20.20C, for the drinking water (groundwater) we saw a similar temperature at 20.28C, the canal water had a slight difference at 18.53C. These measurements were taken during the morning and during early Spring, these factors could be a possible indication for the low temperatures [1]. Dissolved oxygen (DO) percentages were then taken, little lake pond had a DO of 101.50%, drinking water had 93.60% and canal had 93.91%. These percentages are within the same range due to the water being sampled during the

Small strips of land between the main land and a water bodies are known as a Riparian zone. The zones act as a buffer between the interior land and the watershed. They do not make up a large portion of the worlds entire land mass however, they are highly important for ecosystems. Riparian ecosystems share attributes of both aquatic and land ecosystems allowing for greater and a wider verity of biodiversity. They also act as protective barrier for water bodies. Protecting them from soil run off, pollutants and control water temperature by shading sunlight. Along with many other factors that help to create a healthy and prosperous ecosystem. (Riparian area management…,2001) Due to these factors it has become apparent that riparian

Acacia reservation is a 155-acre green space located in the city Lyndhurst. The specific area on which this paper focuses is the central area of the park where on the map a small body of water can be seen. While observations were made in various other areas this is where the majority of the study took place. This body of water is approximately four hundred yards from the roadway on both sides.
