Competition Among Plant Species Paper

This investigation was designed to compare the height of Pteridium aquilinum in a light area and a dark area of Rushy Plains, Epping Forest and to establish if light intensity does have an effect on the growth of Pteridium aquilinum, commonly known as Bracken. From my research it was clear that the height of Bracken is affected by abiotic factors, other than light intensity, such as: soil moisture, soil temperature, air temperature and soil pH so I had to control these factors. I carried out preliminary experiments to find a suitable site where all these factors where constant. For my actual investigation I measure

The independent variable was the type of leaf pack used (coniferous or deciduous) and the dependent variable was the type and amounts of macro invertebrates found in the leaf packs. Macro invertebrates are organisms large

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 bar chart was used to compare the number of species in each transect. In transect A, there were 5 different species. The species in this area were mostly grass, forbs, moss, bugs and beetles. Bugs and beetles made up a small population of this transect. In transect B, there were also 5 species. The species were mostly grass, shrubs, forbs, moss and bugs. In this transect, shrubs were found which makes transect B more diversed than A. In Transect C, 8 species were located in this area. The species included shrubs, grass, fobs, evergreen, trees, dirt, bugs and spiders. New species such as evergreen, trees, dirt and spiders were located in this location. Therefore the test that diversity happens through ecological succession was

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

Competition happens between two or more things. In talking about plants they compete with each to survive. When competing against each other to survive they are using soil, water, nitrogen, and space. In using theses resources and having theses available gives the plant a greater chance in living. Even though plants compete environmental wise it is still scene that there is a lot of unknown to why plants compete. Some researchers believe it could be because of the root size of an individual plant or the size of the seed, which gives it better competition in surviving (Miller, 1995). Different types of competition can happen between plants likes intraspecific and interspecific competition. Miller (1995) believes there is not enough research shown to make a determination as to why competition between plants happens and that there should be research done in looking at the evolution of plants in different environments where they can compete with each other. In looking at competition in plants in class the experiment that we conducted looks at the Brassica rapa in a intraspecific competition in different densities. Miller (1995) found that the B. rapa in intraspecific competition did have increase in the number of flowers that were produced. Comparing this to the finding of Miller, when looking at different densities of plants in a interspecific competition could the B. rapa have more of a change in growth because a higher density will have more seeds and the B.

A plant's growth ability is dependent on its ability to acquire the resources it needs to survive. Competition such as interspecific and intraspecific, limiting resources, and population density affect the fitness level of a plant. This experiment was conducted in order to test the capability of collards and radishes to grow in manipulated densities under interspecific and intraspecific competition. I hypothesized that both collard and radish plants will grow more efficiently in single species pots under low-density conditions. I also hypothesized that in the mixed species plots the radishes will be more fit to survive and grow better than the collard plants in both the high and low-density pots. Both high and low density and single and mixed species plots were planted and results were observed. There was a significant

This report discusses an experiment to study the relationship between the ecological niche and competition. The hypothesis formulated states that if competition traits are identical and resources are abundant than multiple species will be able to coexist, and if one species has an advantage over the others than this species will be more likely to out compete another species for resources. The objective of this experiment is to use a simulation model of a rabbit pen containing four different “species” of rabbits. The model establishes rules for each species that are based on a number of important characteristics reflecting their ecological niches and their competitive abilities. These

Since organisms living in communities form interdependent relationships, a change in the abundance of one species will not only affect the physical and more direct interactions, but could indirectly affect the number of other species within the community as a consequence (Wootton 1993). These indirect affects rise because the interactions between pairs of species are not independent of other species, such as increasing the density of vegetation may increase the survival rate of the prey, reducing the intensity of the interaction between the predator and prey (Wootton 1993, 1994). An

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.

Within communities, organisms compete for limited resources (food, space, mates, shelter). 613 of our native species (plants, birds, fish), compete with 240 introduced plant species, 19 introduced bird species, 9 introduced mammals and 2 amphibians. It is estimated that we have lost 30 native bird species due to this competition.

In general, top predators and green plants are common because of the different community organisms such as the Chippewa Natural Forest that is in total disorder. These species come and go as free spirits and their colonization’s possible extinction are not determined by the presence or absence of other species (Wilson, 1992, p. 163). In fact, the amount of biodiversity is considered a random process in which the species fail to coexist except by accident. Secondly, some species are closely independent, that the food web is design so rigid the symbioses is so tightly bound and the community is virtually a super organism (Wilson, 1992, p. 16). Therefore, one species such as the Acadian flycatcher or goblin fern is a super organism, that thousands

Demons in Eden: The Paradox of Plant Diversity by Jonathan Silvertown is a scientific, nonfiction book that reads a lot like a botanist’s travel journal. It showcases many plant species’ habitats; such as the desert-like climate of Fuerteventura in the Canary Islands and the Kew Gardens in London, when explaining the evolution of plants. However, according to Silvertown (2005), a paradox arises in Darwin’s argument when trying to explain a plant’s evolutionary processes. Darwin’s argument states that organisms that have the most progeny are favored by natural selection. The progeny, adapting their parent’s advantages, will start to reproduce more and more advantageous characteristics until other organisms dwindle to extinction.
