The “squiggly lines” represent the level of the water’s surface elevation in the reservoir of Lake Mead. The graph calculates when the reservoirs level increases and when there is a drought. The reservoir was formed by the Hoover Dam on the Colorado River in
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
The Savanna is By comparing the topography, soil moisture levels, relative humidity, and wind speed of the upland Savanna and Bottomland forest we will be able to compare and contrast between these two vegetation zones. The data collected in the investigation will be used to test the hypothesis that the bottomland forest has a higher degree of shrub layer cover than the savanna. The higher level of shrubs in the bottomland forest might be attributed to the space available for shrub layer species. In addition, the data collected will confirm that the bottomland forest has a higher tree density than the
The topography of the island is also of note. The west end of the island features a closed-canopy forest with more hardwood trees. The east end of the island is better characterized as a “boreal forest,” a term used to describe regions that are mostly covered by coniferous forests. It is good to note that the balsam fir is found on both ends of the island, but that samples used in the study from the west end of the island were, on average, older, but shorter, than those samples found on the east side of the island.
Every forest has a story to tell. By looking closely at its habitants, that story can be interpreted. Much of this narrative is written in the trees: their age, their tolerance to shade, and the rate at which they grow are all characteristics that can imply a lot about their environment. Exploring these relationships and how they connect with each other can indicate the health and history of the land. Heiberg Forest, located in northern New York, was once used for agricultural purposes in the 1800-1900’s. (Nowak, Lecture Notes) Much of the land once used for farming was left to regrow back into a young forest. The life history of different tree species can be determined by examining the most common species in Heiberg.
The annual rate of precipitation, and elevational range once generated a strong foundation for a wide diversity of vegetation
Many people, after reading “The Death of the Moth” by Virginia Woolf or “Once More to the Lake,” would get the general idea that both essays are about death. However, it is apparent to me that both works are really an illustration of the significance of life, but each essay accomplishes this in a different way. I aim to show how these two essays are alike by comparing their similar theme of “carpe diem” as well as some stylistic choices.
Once More To The Lake by E.B White features stylistic and rhetorical strategies such as literary tone and flashbacks. Through the use of White’s flashbacks to his earlier childhood at the lake, the literary tone of nostalgia and reminiscent sentiment is set. The nostalgic attitude of the work contributes to the heartfelt tone of the piece as White transports the audience to a meaningful time in his life. Furthermore, the use of the various flashbacks helps White relate his childhood to his child, creating a parallel between White and his father, when he was his childs age. Through this sentimental tone, the overall meaning of the work is created as it displays how time does not change memories, even if time has changed the present day. Together, these stylistic choices affect the audience's reactions as the reader is able to identify how the lake represents the authors unfading and untouchable memories of his younger days.
In our experiment of field ecology at A-mountain, the purpose were to understand the specific factors that affect the distribution and abundance of plant species at north facing slope and south facing slope. The availability of plants in certain area depends on temperature, availability of water, sunlight and nutrients. A-mountain which is in Arizona has different desert plant that includes; grass, brittlebush, bursage, creosote bush, mesquite, palo verde, fishhook barrel, hedgehog, pincushion, teddy bear cholla, staghorn cholla, chain fruit cholla, prickly pear and others.. and some are specifically found on either north or south side of the mountain. The fact that the south slope receive more direct sunlight than the north facing slope, soil moisture will evaporate faster in south side of the mountain than in the north side thus the availability of different drought resisting plant whereas in north side where there is a slower evaporation due to lack of direct sunlight hence few drought resistant plants compared to south side (Wyant, unpublished data). We predicted that to the south side of the mountain there be will more diversity, evenness and drought tolerant plants species than the north side.
Last but not least, the benefit of planting also including the improvement of soil and water quantity. In the article “Native plants for sustainable landscapes: Establishment and management of lakeshores and gardens” byVera Krischik, an associate professor at University of Minnesota, department of entomology, it represents some benefits of the native plants, that sustain the land with
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
Marianna Jones Tree ecology on two slopes in Battle Park Introduction Forest communities like Battle Park have different environmental factors within their area. On different slopes, depending on the direction it is facing, the soil and area could be wetter or drier. This study is looking to see if the north-facing and south-facing
Environment KLGO is a part of the North American Northwest Coast environmental region, also known to geographers and geologists as Cascadia (Ames and Maschner 1999). The park maintains ecological importance. Lynn Canal is a saltwater fjord which pierces deep into the heart of the Coast Mountains. The Taiya and Skagway valleys

4. Dried leaves were retrieved and weighed. The total tissue loss from initial weight before submersion until now was recorded. Class inputs data and a class mean and standard deviation of tissue loss/ day was gathered for both wetlands for each species
