Comparing the Density and Diversity of Plants in a Non-trampled Area
Plan:
For my coursework I compared the density and diversity of plants in a
non-trampled area of my school and a trampled area of my school. I
wanted to see if the degree of trampling had any affect on the amount
of plants.
For this experiment I will use:
· A key to identify the plants.
· Two twenty five meter tape measures out at 90 degrees to do random
samples.
· A point frame quadrat.
I am going to identify the plants in each area and count them. I will
take many samples of plants in each place. I will sample eleven spots
in the trampled area and eleven spots in the non-trampled area. In
each of the twenty two places I am sampling I will put down my quadrat
and take samples from eleven contact points that will be ten
centimetres apart 0cm 10cm 20cm 30cm 40cm 50cm 60cm 70cm 80cm 90cm and
100cm. The only variable I am testing is trampling everything else
will be the same on both sites. Both of the sites are very close
together, and they both face north so neither place will get more
light. Neither of the places are sheltered so they receive the same
amount of water. The soil has the same solubility and Ph in both of
the sites.
As preliminary work I walked around the non-trampled and trampled
sites with my class we did not change our method as a result of this
preliminary work. When I walked round these two sites I could see that
there were different types of plants in either place.
Prediction:
I think that plants with apical meristems (plants with high points
from which they grow) will not survive in the trampled areas, as their
high meristems will be damaged. Plants with basal meristems (plants
with low points from which they grow) will survive in the trampled
area as there meristems are close to the ground so they will not be
Many variations and species of plants can be found all around the world and in different habitats. These variations and characteristics are due to their adaptations to the natural habitat surrounding them. In three of many climatic zones, the arid, tropical and temperate zone, plants that vary greatly from each other are found in these locations. In this experiment, we’ll be observing the connection between the adaptations of the plants to their environment at the Fullerton Arboretum. The arboretum is a space containing numerous plants from different environments. The plants are carefully looked after and organized into their specific habitat. Therefore, we’ll be able to take a look at the plants within multiple
specimens with the corresponding scientific description, photographs, specific maps and there are drawings that document the research. This collected images of plants continue the artist’s fascination with documentation, community engagement and art as a way to address larger social issues. This exhibit was interning to me to see all the different plant and to know that plants in the city unknown to most there are often edible, medicinal or even poisonous plants.
The story “Death by Landscape” by Margaret Atwood is of a protagonist named Lois who at the time was young but most of the story takes place of when she was an older lady. When Lois was younger, she attended a summer camp named Manitou. From the start, Lois didn’t like camp until she got to the age of ten and met a very good friend named Lucy. Lois remembers their childhood memories they had with one another, until one day Lois’s best friend Lucy disappears. Lucy and Lois are on a trip and all Lois hears is a scream and never once saw Lucy after that. As the story moves along, Lois later started collecting paintings in remembrance of her childhood friend Lucy. Towards the end of the story you can really start to feel
About half of the BBG's 52 acres is devoted to the Systematic Collections: trees, shrubs, and herbaceous plants arranged to show their evolutionary progression. Visitors will also enjoy the Conifer Collection, Daffodil Hill, Oriental Flowering Cherries, and other special collections.
These plants definitely add to its colourful and stunning environment. Our natural surroundings are a playground for our exclusive fauna. It is vital to us to keep them safe. Some animals distinctive to Australia are the kangaroos, wallabies, wombats, dingos, koalas, kookaburras, as well as many more. We are one of the few continents to have all three groups of mammals such as Marsupials and Monotremes & Placentals. Our vast landscapes are mentioned in the lyrics of our very own national anthem for example, “. Golden soil and wealth for toil; our home is girt by sea, our land abounds in natures gifts of beauty rich and rare...” This represents our uniqueness of our own fauna and
Often it seems that in our day and age religion has taken a back seat to science and reason. Many see religion in the same context as folklore, mythology, or as merely moral philosophy. I think this is especially true in the United States of any religion that is not mainstream Protestant Christianity. Even Christianity is not as strong as it once was. However, it does bear relevance in our lives, because the majority of people in the United States still practice some form of Protestantism. However, the focus of this paper is Native American religion as presented in Gardens in the Dunes as a counter to the progress of Protestantism and science. Specifically, I will be looking at the scene of the coming of the Messiah. What is interesting about
How does the vegetation surface type affect the amount of runoff? Speculate why this happens.
As a result of these factors, the flora has adapted to these conditions in a variety of ways including their shape, leaf type, root system, and color. One of the most prominent adapt...
Joe operates a successful commercial landscaping and tree trimming business, and client's keeps his operation extremely busy. Although Joe employees at least 50 workers, with landscaping being seasonal, he experiences a high turnover. In addition to landscaping and tree trimming, equipment rental is also available to the clients, which adds an additional division to the business. With $250,000 of capital, and past year's revenues of $500,000, Joe is looking for guidance to take his business to the next level.
1) It is also cultivated both indoors and out for the production of its flowering tops.
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
A theme in W.P. Kinsella’s “The Thrill of the Grass” is change, for better or for worse, affords the opportunity for us to acknowledge our emotions and love of memories and encourages us to stand up for what we truly believe in. Change, sentiment, reminiscence and defiance are portrayed through the protagonist and the plot in this admiringly, well written short story.
Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...
Seed dispersal is the transport or movement of seeds away from the parent plant in order to help prevent the overcrowding (if this happens plants would not have enough food and light to survive in the area) and help to create new colonies. Thus giving the seed the best chance to germinate in a new location away from the parent plant and hopefully start new colonies. Due to the fact plants have limited mobility they rely on a variety of dispersal vectors to transport their seeds via abiotic (non-living) and biotic (living) vectors. There are five main methods of seed dispersal, animals, gravity, wind, ballistic and water (1). Fire is also another way for seeds to be dispersed but is not as common as the other methods.
