The Vascular Species Of Flora Essay

I readed the most touching book named “Where The Red Fern Grows” by an author that I really like named Wilson Rawls. The way the book was real touching was the way how the author shows the love between a boy and his dogs. Like the way the boy will help his dogs get better when they are hurt and how the boy was protect his dog through anything. I thank Wilson Rawls was trying to show the way that people while do for the thing that they hold the closes to them like the way it is shown in the book “Where The Red Fern Grows”.

     I cannot remember the first time I read Where the Red Fern Grows, by Wilson Rawls. I read it at about age ten, and I have lost count of how many times I read it since. It was a period in my life when childhood was nearly over, but adolescence had not yet set in, and it was a time when animals were my greatest love.

This experiment, which was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs(trichomes). Trichomes create a wider variation which means it is polygenic. The plants that had only a few trichomes were

There were four main invasive plants Himalayan Blackberry, Morning Glory, Reed Canary grass, and English Ivy. Carolyn then started to tell us the difference in the shapes

Biodiversity boots ecosystem productivity where every little species plays an important role in maintaining a healthy community. Maintaining a viable habitat requires lots of efforts, determination and frequency. Invasive plants are a major threat to our natural environment. These invasions change the natural diversity and balance of ecological communities. They threaten the survival of many plants and animals. They are excellent at surviving and reproducing which out-compete the native plants. Understanding these huge consequences let us understand why volunteer activities like this are so helpful and needed. They play a huge part in contributing to our environment in many positive ways. Removing these invasive plants are helping a lot in restoring the habitat and giving native plants greater chance for survival. As time went by, these efforts will slowly help cleaning our atmosphere, providing our environment with fresh air and improve health effects in human (Sagoff,

Human activity has impacted natural vegetation in Texas. According to sources, the region south of San Antonio was originally brush country, with mesquite, small live and post oak, prickly pear cactus, bluestem, buffalo grass, and bunchgrass. Much of this native vegetation has been replaced with agricultural crops. Among the more exotic are the once nearly extinct whooping cranes that winter in the protected Aransas National Wildlife Refuge, near Corpus Christi; the endangered Attwater’s prairie chicken, now bred in a number of Texas zoos and protected at a national wildlife refuge near Houston; and the rare ivory-billed woodpeckers, found mainly in the Big Thicket National Preserve of East Texas. Some, such as the bison, black bear, mountain lion, pronghorn, and red wolf, almost disappeared in the late 19th century but have been saved from extinction through the efforts of conservationists. The Big Bend National Park in far west Texas is plagued each summer by haze that may come from as far away as the petroleum processing facilities along the Texas Gulf Coast. Texas led the nation in 2002 with the most smog days, which PIRG defines as days on which at least one ozone monitor in the state exceeds the national health standard. Twenty-eight percent of the United States' wind power is generated in Texas. According to a U. S. Department of Energy study, the windy states of Texas could generate enough electricity

John Steinbeck’s, The Chrysanthemums, was published in 1938 in a book of short stories, entitled The Long Valley. The Chrysanthemums has been a rather powerful draw for scholars because of its wide gap for interpretations and analysis of its main protagonist character, Elisa Allen and also the unique descriptions used to portray the deeper meaning behind the setting of the story. Themes of sexuality, oppression of women, as well as other numerous types of conflict portrayed in this rather somber short story have made it a popular study among scholars and students alike. Steinbeck also uses literary elements including a dramatic tone, rich symbolism, and personification which increase the stories feeling and value exponentially. Steinbeck

In his short story, The Chrysanthemums, John Steinbeck does an excellent job at portraying the 1930’s Salinas Valley lifestyle through his accurate depictions of realism, regionalism, and naturalism. With the use of realism, Steinbeck narrates the everyday life and challenges of Elisa Allen and her husband Henry. In a conversation between Elisa and a migrant worker, Steinbeck says, “I go from Seattle to San Diego and back every year. Takes all my time. Abou six months each way.

Cheatgrass is the common name for the species Bromus tectorum L. and belongs to the grass family Poaceae (USDA 2015). This invasive plant was originally reported in eastern North America but now it is dominant in the Intermountain West (Huttanus 2009). The genetics of 192 North American populations of Bromus tectorum is studied so far (Huttanus 2009). Cheatgrass grows mostly in coarse texted soils whereas it cannot develop in saline or compacted soil (USDA 2014). In addition, it can invade rapidly in troubled areas such as burned areas, overgrazed rangelands, and cultivated fields. The spreading of the plant to shorter distance occurred as a result of transportation of hairy seeds by wind, birds, water, and to greater distance by vehicles carrying seeds in its undercarriage (USDA 2014).

A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

Fynbos and forest biomes are the main contributors to vegetation diversity in the Garden Route. Indigenous forests in the Garden Route cover 35 765.4 ha. The biome of the Garden Route contains 69% of South Africa’s sub-continent plant species. Approximately 30% of the Garden Route is covered in fynbos. Mountain and lowland fynbos have been converted into pine plantations, having huge effects on the spreading of these invasive plants and the biome of the Garden Route. Alien invasive plants use excessive amounts of water which robs the native plants thereof and are in direct competition for space and soil nutrients against the natural biome. Alien

Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).

According to the Department of Ecology for the state of Washington, the Cabomba genus is a small group of aquatic plants that have invaded several different countries. “The genus Cabomba is in the family Cabombaceae in the major group Angiosperms” (The Plant List, 2013). There are five species of Cabomba: aquatic, furcate, haynesii, palaeformis, and caroliniana (The Plant List, 2013). The most local to our community being the Cabomba caroliniana. This plant is also known for its more common names such as fanwort, fish grass, Carolina water shield, green Cabomba, and Washington grass (Wisconsin Department of Natural Resources, 2015). Cabomba caroliniana is easily recognizable by its “finely [divided] underwater leaves that are feathery or fan-like” (Schooler, Julien, & Walsh 2006). The leaves are olive green and are separated into two types; submerged or floating (Non-native Invasive Freshwater Plants, n.d.). Additionally, the leaves are five centimeters long and emit mucus, which covers the submerged part of the plant (Cabomba caroliniana USGS, n.d.). The floating leaves are smaller and have a more diamond shaped (Cabomba caroliniana USGS, n.d.). They also are fewer than the submerged leaves (Center For Aquatic and Invasive Plants, 2016). Floating on the surface of the water are small white flowers, usually two centimeters in diameter, “that are composed of three white petals and three white sepals” (Schooler, Julien, & Walsh, 2006).

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be
