Soil Composition of the Florida Mangroves
Research Proposal
Background
The mangrove ecosystem is vital to the intertidal community. The complex root systems of the mangroves protect the coastline from erosion and function as a natural water filter. The roots work to trap chemicals, organic matter, heavy metals and cycle nutrients back to sea. The mangroves also serve as a nursery to various aquatic organisms, some of which assist in the filtering process (Chen & Twilley, 1999).
Mangroves have the ability to modify their environment to adjust to the harsh conditions of the intertidal zone. They facilitate the deposition of various sediments which change the terrain or elevation of the coast over time (Ken W. Krauss et al, 2014). …show more content…

Each species has different root structural traits which may correlate with the soil types among them. The specific root length (SRL; root length per biomass) had been shown to correlate with higher soil volume. The larger the SRL, the higher the volume. One study found R. mangle to have an SRL of 0.55mg, 1.05mg for A. germinans, and 1.70mg for A. racemosa (Ken W. Krauss et al, 2014). This information supports the predictable zonation patterns of mangrove species.
R. mangle is located on the coastline, easily identified by its prop roots and smooth bark which extend from the water. A. germinans choose to live on the edge of land and is identified by its characteristic air root pneumatophores. L. racemosa primarily lives on dry salty land and excretes salt through its leaves, giving them a white underside. Its roots are not visible above the

    Through photosynthesis, mangroves provide nutrients and oxygen to animals and plants. As mangrove forests connect the ecosystems of the land and the ocean, their significance in stabilizing the ecosystems is undeniable. Their forests provide a huge amount of food resources. A lot of animals and plants spend their life cycles with mangroves (Ecological and economic value of mangroves, 2015). The root systems of mangroves take up substances and lessen water contamination.

  • Conrad's Beach Ecological Succession Report

    1014 Words  | 5 Pages

    When reviewing figure 3 it has been noted that most of the species are more abundant further in the woods and the most significant change is in the moss and the amount of coverage which was substantially different depending upon the distance from the dune to the woods. The numbers fluctuated - dropping slightly at 60 m and rising to its highest point at 75 meters. Trees also had a very noticeable change in their percent coverage starting below 10% and rising close to 5 percent every 15 meters. The other plants did not show any specific trend of growing more the further way from the dune but this could be due to where the quadrants were placed as each team placed their quadrat down every 15 meters which resulted in a lot of ground left uncalculated. This could be the reason for lack of trends with other plants.

    It is positively gravitropic, while the shoot is negatively gravitropic. Root hairs are then later developed from the radicale. Both Douglas-fir and red alder have epigeous germination (cotyledons pushed out of ground). Mycorrhizal fungi could appear in Douglas-fir lateral roots, while red alder has nitrogen fixing nodules form. Both species’ habitat are primarily in the Pacific Northwest.

  • Camosun Bog Characteristics

    439 Words  | 2 Pages

    Since the bog is home to many types of rare plants, its ecological strucuture is quite unique and special. In particular, the sphagnum moss absorbs and holds moisture that is slowly released into the atmosphere. Because sphagnum is very water absorvant, acidic, and antiseptic, it has had many significant benefits to the Musqueam People, such as using the moss to disinfectant bandages and baby diapers. Of particular notice is the importance of water in the bog: water released in the bog is acidic, and it acts like a solution that prevents bacterial growth, slows decomposition, and reduces nutrition availability. In addition, dead/decayed plants create carbon sink: a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period.

    A hydrilla grows a long steam that has many leaves on it as well as tiny white flowers on them which float above the water. They are an aquatic plant which means they live in water such as clean water, including lakes, ponds, rivers, streams, and marshes. Seen mostly in the Southeast of Florida and in their habitat they form dense mats of vegetation, can grow with little light, and more efficent in taking nutrients than other species. Florida faces many problems within their water bodies and waterways. The aquatic plants pollute 96% of the public lakes and rivers.

Population decline has made many beaches actually closed or fenced off during breeding seasons for Piping Plovers because of illegal hunting for their feathers. Many of the common vegetation in this area are Yellow-horned Poppy, Mile-a-Minute and Oriental Bittersweet.

    The Florida manatee is deemed as one of Florida’s most symbolic marine mammals in the state. Manatees can be found in salt water in the West Indies and fresh water habitats in Florida and coastal regions. Manatees first appeared in Florida about 15 million years ago. Manatees are very large marine mammals that are related to elephants. ‘’They are grayish brown in color and have thick, wrinkled skin on which there is often a growth of algae.

    These banks contain coral rubble, seagrass and macroalgae with other invertebrate taxa, which play a key part in the ecosystem. The bank systems contain essential fish habitats, which provide sheltering and foraging grounds. Past studies have indicated these fish assemblages showed a high diversity and biomass of coral reefs. Most of the biomass in the Florida Keys ecosystem is made up of species that stay in channels for most of the day. These signs show that the bank systems are important for the FKNMS for providing a structural support and high productivity for the biodiversity.

    A costal ecosystem restoration program was invented by Congress in the Water Resources Development Act of 2007. The state is expected to spend nearly $1.2 billion over the next three years on protection and restoration projects. They have yet to come up with the money, but they have been thinking of solutions. One solution they have been thinking of is the sediment required to replenish the wetlands will come from land scattered throughout the basin. Even though sediments are crucial to rebuilding the wetlands of the Mississippi River Delta, additional nutrients flowing through river diversion could potentially impair inland waters of the state.

    Abstract: The purpose of this experiment was to determine whether the amount of topsoil would influence the growth of radish plants. It was hypothesized that if the amount of topsoil increased by 50% would increase because topsoil contains the essential nutrients which are required for proper plant growth. The principle findings indicated that a medium amount of topsoil is ideal for plant growth as the radish plant potted in 50 ml of topsoil experienced the most growth in comparison to the radish plants potted either in 25 ml or 200 ml of topsoil. Introduction: A healthy layer of topsoil comprises of a mixture of clay, sand, silt, and humus that supply the plants with vital nutrients, such as nitrogen, phosphorus, potassium and other necessary
