  • Using Permaculture Principles When Designing A Pond

    Marginal plants, can be decorative as they can help blend the edges of the pond into the surrounding ground, but also provide shelter from the wind and the rain. Because they grow on the edges of the pond, they also serve as a barrier for fish and other aquatic animals from possible predators. Some examples of edible marginal plants are, Vietnamese Mint, stonecress, and rainbow parsley. Oxygenating plants, have roots submerged in the soil, but their leaves unlike with the floating plants are completely submerged underwater. Oxygenators help keep the water clear by absorbing excess nutrients, as well as release oxygen which helps support aquatic life such as fish, and beneficial aquatic insects. Submerged plants must be carefully maintained as they can quickly dominate the habitat. Therefore it is important to remove excess plants, as well as cut the remaining plants back regularly. Some examples of of oxygenating plants, are water milfoil, hornwort, and water primrose. Floating plants, float on the surface of the pond. They do not need soil, as the extract their nutrients from the water. Floating plants are extremely beneficial as they control algae. Floating plants control algae by restricting light, and…

  • Hippca Habitat Destruction

    the ecosystem. If climate change is not alleviated, and ocean temperatures continue to rise the whales will continue to migrate to more favorable habitats or face the risk of starvation, and death. Furthermore, overexploitation has been a consistent problem for whale populations since the whale has been hunted for a variety of…

  • Daphnia Lab Report

    The Effect of pH levels on the Motility of Daphnia in Lake Ecosystems Introduction: The production, transportation, and use of chemicals by chemical industries can result in chemical pollution. This leads to a harmful effect on ecosystems and their balance of life (Linlin, Chen, 2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also…

  • Water Pollution Effects On Aquatic Life

    the negative effects it is having on freshwater aquatic life. Pollution is creating a positive feedback loop in our freshwater aquatic life, including the killings of many of freshwater wildlife. Through the analysis of several different articles and books, this review will look over how eutrophication, acid rain, and heavy metal pollution effects freshwater aquatic life. Eutrophication is a process in which there are extra fertilizers, and other types of materials which runs off into…

  • Shark Culling Research Paper

    Dinoflagellates are marine plankton, they are producers and have eukaryotic cells (meaning that the cells have a nucleus). Diatoms are unicellular, they are a type of algae. Cleaner shrimps free other organisms of parasites. Copepod are small crustaceans found in marine ecosystems. Ptereopods are a type of sea snail/slug. The type of squids, sharks and small fish found in a marine ecosystem depend on the abiotic elements. Amphipods are also a type of crustacean found in saltwater and fresh water…

  • Ada Hayden Lake Essay

    Nitrogen and phosphorus are the major limiting nutrient elements in a variety of aquatic ecosystems and are altered by anthropogenic activities; such as row crops, feed lots, and humans (Elser et al. 2007). Larger inputs of nitrogen cause an abundance of phytoplankton and macrophyte production (Ferree and Shannon 2001).The purpose of this study was to examine nitrogen and phosphorus levels at Ada Hayden Lake in the comparative context of their effect on phytoplankton abundance as well as…

  • Invertebrate Diversity

    dissolved oxygen levels largely determine the size and diversity of the community the habitat is able to support (L. R. Bodensteiner et al., 2011). In this present study, two freshwater stream environments were studied: riffles, which are rocky areas with fast-flowing, shallow water, and pools, which are areas of deeper, slow-moving water. The effects of biotic factors on species diversity have already been studied. Competition between freshwater, inhabiting organisms generally results in a…

  • River Flow Alteration Essay

    diversion weirs, interbasin water transfers, and extraction of water from aquifers have drastically changed flow regimes. The primary water demands include use for agriculture, hydropower generation, industry, and domestic supply, which have impacted ecological ecosystems (Rosenberg et al., 2000). The importance of a river’s flow regime for sustaining biodiversity and ecological integrity has been well studied over the last past 4 decades. These studies have characterized flow regimes on a…

  • Ecosystem And Terrestrial Ecosystem

    A terrestrial ecosystem is an ecosystem found only on land. There were six primary terrestrial ecosystems which are tundra, taiga, temperate broadleaf forest, tropical rain forest, grassland and desert. Terrestrial environments are segmented into a subterranean portion from which most water and ions are obtained. An atmospheric portion from which gases are obtained and the physical energy of light is transformed into the organic energy of carbon-carbon bonds through the process of…

  • Animal And People Mind Analysis

    Class discussions included a range of topics from common fish living in the local watershed to the importance of water clarity. These discussions are key to understanding how a fish or other aquatic organisms behave when in an environment that is not clean. Research done in areas such as Lake Tahoe showed that invasive species can affect the water quality and make it unable for fish to survive. This is due to invasive species having the same diet as fish. The most interesting part of this…
