Disadvantages Of Species Diversity

Species diversity is characterised by the diversity within an ecological community (McGinley, 2014) that incorporates both the total number of species in a region and the degree to which the abundance of each of the species is similar; these concepts are termed species richness and species evenness respectively. The Simpson’s Index of Diversity is a measure of the biodiversity within a community and is derived the number of species and their relative abundances (Knox et al., 2014). The Simpson’s Index of Diversity score ranges from 0-1; the higher the score indicates a higher diversity.

The purpose of this experiment is to observe secondary succession at Umass Dartmouth and test the prediction that diversity increases through ecological succession. Students went outside to the lawn underneath the wind mill on campus. 3 transect sites were located by the instructor. Students predicted the species and percent cover of each species on each trail site. Bar charts were made to compare the number of species in each transect. Pi-charts were made to compare the percent coverage of species in each transect.

Biodiversity means the variety of life forms/organisms in an ecosystem, biome or entire planet. Globally, biodiversity is not evenly distributed. It generally increases from the poles towards the equator as around 50% of the world’s plants and animals live in tropical rainforests. This is because of the proximity to the equator causing a warmer, more moist, stable climate which means plants grow better and can support more species higher up in the food chain. Standard of living is the level of wealth, goods and

In Idlewood, the open area was the second to least populous and had the least number of different species. While Tyler State park’s open area has the second to most diverse and populous recorded number of birds. The open area in Idlewood included a grassy field that was cultivated by humans for recreational reasons, but the open area in Tyler State Park included a farmland and the shrubs alongside of it which is the cause for the difference in population and diversity among the two areas. All habitats have limited space because of their boundaries (which were established in the classroom and can be found in the Field Study) but some habitats, such as the young forest, are able to provide more space for more species than other habitats, such as the wetlands. In regards to species diversity, Idlewood’s mature forest has the highest species diversity percentage at 8.52 because of the species: population ratio. Tyler State Park’s young forest has the highest species diversity percentage at 12.88 because it had a higher number of different species than the other

One advantage of sexual reproduction is that these organisms generally have greater genetic diversity. Organisms who reproduce asexually, on the other hand, are essentially clones of each other. This means that their predators can adapt to hunt them easily. The diversity of sexually reproducing organisms allows them to stay a step ahead of their predators because of their genetic variations and their ability to adapt via natural selection (Brockmyre 2015).

“Biological diversity is of fundamental importance to the functioning of all natural and human-engineered ecosystems, and by extension to the ecosystem services that nature provides free of charge to human society ”(Lloyd, 2014). Biodiversity is very important to both plants, animals and humans on Earth and if one species is destroyed it throw the balance off .

Biodiversity loss threatens to disrupt the function of ecosystems, with the potential of consequences for humans as well. Often this loss is measured by species extinction rates, but considerations should be made to include population diversity with measures including changes in size, number, distribution and genetic composition of population and potential implications those changes may have (Luck et al., 2003). Avise (2004) goes as far as to say biodiversity is genetic

The sparrow had a total of one species with a relative abundance of 0.0526. The earthworm had a total of six species with a relative abundance of 0.3158. The red-headed woodpecker had a total of one species with a relative abundance of 0.0526. The bigger brown spider had a total of one species with a relative abundance of 0.0526 (see Figure 1). The total number of species in the wooded area was nineteen with the species evenness of 0.7823. It also had a Shannon diversity index of 1.6266 and species richness of eight (see Table 1). The twelve different species at the water’s edge site are turtle, buzzard, deer, frog, beaver, tiny brown spider, small black bird, small yellow and brown stripes spider, dark with brown stripes spider, water spider, tibellus spider, and dog. The turtle had a total of five species with a relative abundance of 0.1515. The buzzard had a total of three species with a relative abundance of 0.0909. The deer had a total of one species with a relative abundance of 0.0303. The frog had a total of one species with a relative abundance of 0.0303. The beaver had a total of two species with a relative abundance of 0.0606. The tiny brown spider had a total of one species with a relative

So we will talk about biodiversity first. Biodiversity is a group of different living organisms from around the world in one community. And biodiversity helps the biosphere because they can produce better and help other plants and humans in need. Some plants and trees have different characteristics regarding to their species.

The three levels of biodiversity are as follows: diversity of the ecosystems, diversity of species within the communities and diversity within species. The loss of species within the ecosystems and within the community can cause a catastrophic result, as species live and feed on other species. Species close to extinction are endangered species, therefore protecting them from predators and offering the chance to reproduce and repopulate. Unfortunately, with little support within the environment, a species can become extinct due to population density. Proper monitoring of an endangered species is required in order to keep species actively reproducing and changing with the environment around them.

On May 8th the grades Biology students went on an excursion to the rocky shore Pt. Cartwright. Rocky shores are where the land meets the sea. On the Rocky shore there are different zones that are based on tidal level, this means the rocky shore is a quickly changing environment and due to this unique condition it gives a large biodiversity. Biodiversity is the term given to the variety of life on Earth. It is the variety within and between all species of plants, animals and microorganisms and the ecosystems within which they live and interact (Wwf.org.au).

Species (populations of interbreeding organisms) change over time and space. The representatives of species living today differ from those that lived in the recent past, and populations in different geographic regions today differ slightly in form or behaviour

Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just ecosystem of one garden, it has the same importance because without it nature loses its ability to perform major functions needed for life on Earth, as it is oxygen production. Trough this investigation, two different ecosystems will be explored and

Franck and Brownstone define biological diversity as 'the variety and variability of living organisms and the biological communities in which they live' (36). Decades of progress in both the scientific and political arenas have advanced environmental legislation to protect biodiversity at not only the ecosystem level, but for specific species and genetic material as well. Research has shown the importance of every organism and their role in the global ecosystem, and legislation has gradually matured to protect not only species which may become endangered, but the habitats they need to survive as well. Growing consciousness surrounding environmental issues has enabled these protections to be

diversity impact on workplace in positive and negative also. Effective communication is necessary for any business ,we can not company our message effectively without effective communication. In diverse workforce people have different languages. So that they fail in communicational issues .
