Multiple plants, like red trillium and red pine, came from other regions so there is a lot of diversity in the GLSLL. Each plant contributes to the environment,
The book you chose Where the Red Fern Grows by Wilson Rawls was a book I enjoyed. I liked the story because the 10 year old Billy Coleman was always seeking new adventures. He was at first determined to buy two hounds. After he bought his two hounds, he went on adventures and competed in a contest with them to kill coons. Every night he and his dogs would be determined to kill the coon they found.
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.
Where the Red Fern Grows is about a kid and his two dogs. The kids name is Billy and he lives on a farm. This book is mainly about a kid who is trying really hard to get two new dogs which he saw in a newspaper. He really has wanted dogs for a while and found some for a good price. Billy wants two new dogs very badly, but his grandpa can’t afford them.
To test the hypothesis that mistletoe abundance effects tree health and diameter, we quantified the number of trees that did and did not possessed the Big Leaf Mistletoe along a 50m plot from the perennial river edge. We did this by evaluating each tree we saw by eye, looking for signs of mistletoe on the tree. We them recorded the diameter of the trees and a quantified scale of health for the trees between one and three; three being good health and one being low health. We also recorded the number of different growths of Big Leaf Mistletoe on the trees that possessed mistletoe. We did this for the first 50 trees we came into contact with, within our 50 m perimeter from the river.
An unknown author once said, “All the hard work, all the sacrifices, all the sleepless nights, struggles, downfalls, it all pays off.” When the author said this quote, they meant that if you have a goal in life and you are trying to catch your dream. Your hardwork will pay off if you work for it. Never give up even if you are struggling it will pay off. In the book Where the Red Fern Grows by Wilson Rawls, he shows that Billy is very hardworking.
In the novel The Westing Game by Ellen Raskin, Sam Westing’s pairs his heir in a game in a way that ends up helping them. This can be seen in the healing relationship between Turtle and Flora: Turtle helps Flora to deal with her grief and Flora helps Turtle by becoming a kind mother figure to a neglected kid. Turtle’s mother doesn’t value her and doesn’t treat her well and Flora, who had recently lost her daughter is lonely and needs companionship and someone to care for. The relationship between these characters changes over time.
By cutting down trees, many eco-systems get destroyed and many animals will not survive. I have noticed how this process occurs a lot in Florida. The Florida Everglades once compromised most of the state, and due to human development almost half
The weight of the Kudzu on plants is enough to stunt growth and even break branches. The accumulation of these effects contribute to the ever decreasing plant diversity in a region that has been overtaken by this highly invasive species. Kudzu is able to outcompete bushes and shrubs; limiting food sources and vital shelter to a number of native fauna. The limitation on plant diversity that Kudzu has caused will eventually limit the animal diversity. The Kudzu problem continues to grow, both literally and figuratively.
Ryan Malakie Principals of Environmental Science 10/8/2015 Pueraria Montana (Kudzu) Pueraria Montana or kudzu is a vine originating from the pea family, which can grow at a blister pace of one foot per day. Kudzu has compound leaves with 3 leaflets each measuring about 10 centimeters wide and 10 centimeters long. The woody vine of the plant grows to be about 2 centimeters in diameter, producing small purple flowers that smell like grapes. Kudzu is considered to be an invasive species in the United States due to its fierce growth that blankets the landscape, out-competing any native species.
The Current Problem Pueraria montana, commonly known as Kudzu, once introduced into an environment kills other vegetation and takes over a landscape. According to Bergmann, (2016), “Kudzu kills surrounding plants by suffocating them under a cover of its leaves, encompassing the area with woody stems and tree trunks, and breaking branches or evacuating entire trees and shrubs.” Not only does Kudzu kill plant life around it; it also grows at an alarming rate of about one foot per day. Mature vines can grow to about 60 - 100 feet in length and spreads by vines that stem at the nodes to arrange new plants (Bergmann, 2009). The researcher proposed several solutions aimed at destroying, limiting growth, or creating a new market for controlled use.
Unintended species brought over by loggers and settlers include fungi and weeds that are detrimental to the existing ecosystem. In 1910 a fungal disease known as “white pine blister rust” was introduced and resulted in a substantial reduction of the existing Western white pine (1). The forest succession, as it is happening in the Pacific Northwest, is making the forest more “homogeneous in their composition and structure” especially since the only trees replanted after logging where Douglas-fir (1)(4) . This makes the ecosystem more vulnerable and weaker to invasive
This act has a lot of cause and effects. Removing trees leaves animals with no place
Eucalyptus has been in Brazil for over hundred years and although it has some of the characteristics, so far it has always failed to behave like an invading plant (Silva et al., 2011). Thereby, the areas where eucalyptus is planted are usually surrounded by environment conservation areas or even by water (BCH,
Another relationship in the Daintree Rainforest is parasitism between the Strangler Fig(Ficus aurea) and its host tree. The Strangler Fig is the one that's being benefited in this relationship because the host tree ends up losing its nutrients since it gets wrapped around by the Strangler Fig which blocks off light that is used for photosynthesis. The roots of the Strangler Fig also compete with its host tree for water and nutrients, so as it grows the roots gets thicker and blocks off all water and nutrients(Schaffner, 1). This can even end up causing the host tree to
