Spectacular Changes In Alpine Environment Essay

The alpine biome is a beautiful biome that is very important on earth. Some of the most famous sites are in the alpine biome, including Mount Everest. But now humans poach in the alpine biome, so now lots of animals are endangered. Even though the hard climate causes problems, plants, animals and humans survive in the alpine

Reyna Grandes’s Across a Hundred Mountains was written in 2006, it is a stunning and heartfelt novel about migration, loss and discovery. It was published by Washington Square Press and its two hundred and sixty-six pages will captivate the reader from the beginning. The novel depicts the desperation of undocumented immigrants who make the dangerous journey across unfamiliar land to reach the border for “El Otro Lado” (the United States). The author, Reyna Grande gives the reader a glimpse of the everyday struggles these families are faced with and the heart-wrenching decisions made in the pursuit for a better life. There are different themes in this novel, they range from fractured family ties to heartbreaking poverty affecting the family and how religion is used to seek relief from these events. Therefore, an evaluation of the novel will be made on the social issues affecting these individuals, the challenges they face, and apply the ecological perspective along with its strengths. Lastly, an explanation will be given in which a social worker can help to address the issues that affect these individuals.

For my summer reading, I chose to read Mountains Beyond Mountains: the Quest of Dr. Paul Farmer, a Man Who Would Cure the World. I chose this book without reading the description and mainly based my selection on the great reviews for this book online as well as the fact that the author, Tracy Kidder, had won a Pulitzer Prize in the past. Ultimately, this book turned out to be as remarkable as the reviews stated it was.

Plants are found everywhere on earth, up high on the ridge and down low in caves and caverns. The types of plants that live in these places depends on many factors. These factors are separated into two different categories, the biotic factors and the abiotic factors. Some of the biotic factors include, predation, competition, and habitat destruction. Plants with limited competition and large amounts of resources will be in a higher abundance than plants with limited resources and higher competition rates will be confined to areas and either out competed or will be the dominant species. Certain plants adapt to these factors and thrive and others don’t do as well. Some of the abiotic factors include, sunlight, water, temperature, and wind. These

6. Describe several adaptations that enable plants to reduce water loss from their leaves. Include both structural and physiological adaptations.

For those seeking a secluded mountain home there would be none better than Appalachian Mountain real estate, as the starting point.

Biomes are appropriate conditions for organizing the natural world because the organisms that live in them common constellations of adaptations, particularly the climate of each of the areas and the characteristic vegetation types that develops in these divisions. It should be understood that the climate is perhaps the most important in determining classes of individuals who may live in an area and the ways they should be amended to live under different conditions of temperature and precipitation and seasonal distribution of these factors element. Every place on Earth has its own climate, influenced by both macroclimate regions as the particular microclimate. The soils are very important because they are essential to determine the types of plants that will grow into a bioclimatic zone in partical, in addition, also as substrates for animals serve. In turn, the soils are heavily influenced by regional climate, as well as the geology of the bedrock. At the same time we have to keep in mind the diversity of plants like the flora just like the diversity of the fauna as well as the adaptation of both.

Adaptations in terrestrial environments involve the structural and functional qualities of the organism, to achieve the adequate intake of oxygen and other essential substances for the animal to survive, the evolution of more complex anatomical structures were required. Gravity is stronger on land than water, which means terrestrial organisms have to be more structural than aquatic organisms. Also, the balance of gas exchange with water loss is a key feature to survive in land. For example plants, when doing photosynthesis require carbon dioxide and water to produce oxygen, at the end of this process a lot of water is lost and terrestrial plants have to compensate the water being lost and the water taken from soil. Furthermore, the dispersal of gametes by wind or other animals have helped plants reproduce in large amounts and create varieties of species of the same kind. Short-term weather patterns as well as long-term climate conditions based on precipitations, temperature, wind, humidity as well as other factors are survival obstacles that organisms in land have to adapt to live; endothermic organisms have to maintain a constant internal

MORGANTOWN, W.Va.--With the West Virginia University fall camp underway, one of the things the Mountaineers are continuing to work on is the passing game.

Lakes and ponds are not common and occupy less than one percent of the surface. On the other hand, due to the severe climate and shallow body of soil, vegetations, up in the North are commonly sparse, ground-hugging and dwarf-like in form. The low variety of vegetation, which the diversity of plants yields only about 150 species, makes this region a barren plain. The main vegetation in upland areas consists of lichens and herbs, whereas water lowland sites will be predominated by sedges and mosses. Moreover, this land is also lacking the diversity of wildlife, that the limitation on plants greatly restricts food which inhibiting animals can consume. In fact, the habitat for a few animals

Tundra plants over the years adapted to sweeping winds and disturbances of the soil. Another adaptation is that they are short and cluster together to help endure the cold. Also they can carry out photosynthesis at low temperatures and low light intensities. Plants aren’t the only things that have had to adapt to the conditions, animals have had to as well.

As I pick up speed I feel the wind push harder and harder in the opposite direction, but my jacket breaks its bite. The reflection of the sun on the stark white snow makes the path ahead harder to see; my destination is still visible, its dead ahead. As I close in I have second thoughts but it's too late for that now. I lean forward to ride my edge and make a quick turn as I launch off of the jump which sends me into a spin until I'm facing my original direction, 360 degrees then my snowboard touches the ground again and I land it. Well, at least I planned on landing it. However, the reality of the situation was different, I ended up hitting the hard snow with my head and shoulder. That happened on my most recent skiing/snowboarding trip. I've been skiing for as long as I can remember but the past few trips I have snowboarded instead. Skiing and snowboarding are some of the things that I'm most passionate about, but the most important part is doing those things with my family and friends. So, get ready to learn some knowledge about me.

When the sun slowly peeps over the range of mountains, birds shake the morning dew off their feathers and give a cheerful song that would lift even the most sorrowful of spirits. A light fog wraps around the mountain range, reaching to touch every bit of life thriving there. The slight chill in the air is enough to give a gentle shiver, but not enough for the need of a jacket. A breeze tickles the trees, making their leaves shake and sway with laughter. Sunlight seeps in past the thick canopy of branches with hopes of being able to reach the damp mountain earth. The mountains are the best place to live to be relaxed, see the most beauty, and never get bored.

Our lab investigated the morphological characteristics of leaves found in the sun and shade on various species of maple and oak trees around campus. Our null hypothesis was Acer and Quercus acclimate similarly with regards to SLW (specific leaf weight), size, and sinuosity. Our hypothesis was Quercus acclimation is greater than Acer SLW, size, and sinuosity. We tested these hypotheses by picking small sections of a branches from both maple and oak trees. A group was assigned either a maple or an oak tree, and needed a total of three different trees per group. Once three different trees were chosen, groups needed three shade leaves and three sun leaves of off each different tree. In total, each group should then end up with 18 leaves for testing. After collecting the leaves, we ran them through the LiCor 3100 leaf area meter to identify the area of each leaf. Major results found by the classes’ mutual data was each one of our p-values were greater than .05. This means that we failed to reject the null hypothesis. Thus, the lab results do not support our hypothesis that Quercus acclimation is greater than Acer SLW, size, and sinuosity.

The plants that grow in saline soils have diverse ionic compositions and a range in concentrations of dissolved salts (Volkmar et al., 1998). These concentrations fluctuate because of changes in water source, drainage, evapo-transpiration, and solute availability (Volkmar et al., 1998). Due to these varying conditions, plant growth depends on a supply of inorganic nutrients, and this level of nutrients varies in time and space (Maathius and Amtmann, 1999). Either extreme condition concerning nutrients results in deficiency or toxicity in plants, and this is demonstrated by salt tolerance (Maathius and Amtmann, 1999). These conditions vary according to the plant species and growth conditions. Little is known about the genetic basis for diversity of salt tolerance in plants, and this could be partly explained through the definitions given for salinity.
