Increasing the Diversity of Plants - 914 Words

According to the Simpson’s diversity index calculations of all the sites in figure 7, Site 3 had the highest index reading of 0.701 out of 1. With 1 being the highest possible value, it indicates very high diversity while 0; the lowest possible value, indicates no/very low diversity. This suggests that 0.701 is a high reading, indicating high diversity of plant species. The analysis of the first hypothesis ‘There is a direct correlation between the diversity of plant species and the relative humidity at each site’, will help explain why site 3 had the highest diversity index reading when compared to the other sites. To answer this hypothesis, data will be used from graphs in figure 2, 3 and 4. It can be suggested from figure 2, 3 and 4 that the abiotic conditions of site 3 have proven to increase the diversity of plants when compared to other sites. For plant A, according to figure 2, the humidity (rH) decreases from 64% in site 2 to 50.1% at site 3 while the tota l number of plant A increases from 9 in site 2 to 80 in site 3. Even though the diversity of plant A increases with a decreased relative humidity in Lamma Island, this is not supposed to occur in general according to theory as higher levels of relative humidity are supposed to increase biodiversity, not decrease biodiversity. Theory suggests that a higher level of humidity is supposed to decrease the effect of solar radiation while a lower level of humidity is supposed to increase the effect of solarShow MoreRelatedOn the Brink of Extinction Essay878 Words   |  4 PagesIntroduction Biodiversity is the grand diversity of all life on Earth and the interconnections that support these forms of life. This astonishing diversity supports the human existence by providing numerous priceless resources such as food, fuel, and medicine. Many of these resources can not be duplicated by the human race. For these reasons it is obvious that the environment and the biodiversity that it supports are detrimental to human survival. There is one major problem that is growingRead MoreCoca Cola1381 Words   |  6 Pagesresearch is to be used to evaluate the environmental issues and work force diversity of Coca Cola, also strategies and recommendations on these issues will be explored. Introduction: Jacksonville Consulting LLC is a small firm located in Jacksonville Florida. The President of the firm is Bill Jones and the Vice President is Pamela Smith, At Jacksonville Consulting we specialize in helping companies with environmental and diversity issues.

Plant ecology is important for predicting plant distribution and abundance for the maintenance of our ecosystems. Studying plant-consumer interactions yields information on ecosystem and economic stability, as well as community structure that can all lead to a variety of conservation efforts. Herbivory is a driving factor that can be detrimental to plant communities like the spruceRead MoreThe Effects Of Germplasm On Plants And Tissue That Helps Main tain The Breeding And Conservation Essay1213 Words   |  5 Pagesa few cells from a plant (3). It is a living tissue that grows into a new plant (3). National Plant Germplasm System global food is an availability and security for the agricultural production. The importance of germplasms is to produce plants for food, fibers, animal feeds, industrial and medicinal purposes, and for landscape and ornamental uses (4). With the increasing knowledge, many farmers are learning how to plant breeders, increase crop yields, and enhance quality. Plants carry DNA, which isRead MoreThe Progression Of Succession Through Facilitation And Other Species Interactions1370 Words   |  6 Pagesvariations in diversity among the five dunes. The third was to examine percent coverage amongst stages to see how the species are influenced by their environment. A fourth to examine the proportions of grasses and forbs to understand the properties of grasses on late succession. Last, we examined how counts o f focal species change with dune age among herbaceous species and woody species. Results show that organic material increased among different stages of succession. When measuring diversity, by theRead MoreBiodiversity626 Words   |  3 PagesMarine biodiversity tends to be highest along coasts in the Western Pacific, where sea surface temperature is highest and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots and has been increasing through time but will be likely to slow in the future. b. bioinformatics-is an interdisciplinary field that develops methods and software tools for understanding biological data. As an interdisciplinary fieldRead MoreThe Potential Factors Affecting The Environment1107 Words   |  5 Pagesbetween all types of living organisms such as microorganisms, plants and animals available in a particular area covered by natural conditions. The term biological diversity first coined by Norse and Mc Mangus in 1980 (Rawat and Khare, 2010). According to the U.S. Office of Technology Assessment (1987), biological diversity is the variety and variability among living organisms and the ecological complexes in which they occur. Biological diversity fabricates variability of gene, species and ecosystem (PRead MoreThe Production of Sesame in Ethiopia Essay examples1457 Words   |  6 Pagesrecognized as a cultivated species (Getinet et al. 1998). Even though the origin of sesame is still in debate, Mehra (1967) and Mahajan (2007) considered Ethiopia as th e origin of cultivated sesame. Bedigian (1981) argues that, owing to the wide genetic diversity in East Africa (Ethiopia), it is reasonable to assume that this subcontinent is the primary center of origin and India would then be thought of as a secondary center for sesame. Sesame seed, also known as sesamum, gingelly, benniseed, sim-sim andRead MoreBiodiversity. Biodiversity Is The Variability Among Living1684 Words   |  7 Pagesother aquatic ecosystems. This includes diversity within species, between species, and ecosystems. The three main aspects of biodiversity include genetic diversity, species diversity, and ecosystem diversity. Biodiversity levels can change over time due to long-term natural processes including habitat loss. The importance of biodiversity is vital to all life on earth, determining extinction, evolution, and the fate of our planet’s ecosystems. Genetic diversity is the key ingredient from which all otherRead MoreBiological Diversity and the Ways It Can Be Destroyed, Restored and Maintained1223 Words   |  5 Pages For my topic I chose to explore biological diversity and ways that it can be destroyed, restored, and maintained. In class, we were taught that diversity is the number of distinct species of animals, insects, plants, etc. that are living in a particular area. We found out that diversity is greater in the tropics and less towards the poles. This is called the Latitude Diversity Gradient and could be due to one or more of three theories. They are the cradle hypothesis that says the area where species
