The Three Levels Of Biodiversity

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.

Tourism is the world’s largest industry with nature-based ecotourism seeing rapid growth since its initial arrival in the 1980s. It is estimated by the World Tourism Organisation that nature tourism generates 7% of all international travel expenditure (Lindberg, 1997) and this figure will have increased rapidly over recent years. It’s increase in popularity is due to a number of factors; tourists becoming increasingly bored of the typical sun, sea and sand holiday’s, the increase in global awareness or environmental issues such as global

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

“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 .

When a habitat is fragmented, the amount of edge habitat increases at the expense of interior habitat. Species dependent on interior habitat suffer, while edge-dependent species, including invasive species and predators, thrive. Highly fragmented forests cannot provide the food, cover, or reproduction needs of interior forest species. Predators such as crows and raccoons and nest parasites like the brown-headed cowbird find target nests more easily

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.

It is the variety within and between all species of plants, animals and micro-organisms and the ecosystems within which they live and interact.” The reason why biodiversity is so important because it ensures the ecosystem sustainability. Without biodiversity the Earth becomes weaker. In the Machine Stops, each person had their own pod with everything they could ever possibly need, giving them no reason to go out and interact with others. It is mentioned that Earth is inhabitable, but throughout the story there is no mention of the pods holding any kind of plants or animals, and because humans have no reason to interact, it can be assumed that no offspring has been created either.

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.

Genetic diversity can help a species survive. The greater the number of different alleles that all members of a species possess, the greater the genetic diversity of that species.

The area of an animal has an enormous influence in affecting their producers contribution to their size. A portion of the animals on the

Genetic variation is a topic that has come towards the forefront of discussion as we learn more about genetics. Genetic variation is the variation of alleles in the gene pool. Specifically, in this paper, I will be focusing on the genetic variance of large population sizes and small population sizes in the same species. It has become widely accepted that if the population size is smaller than the genetic variance is smaller as well, thus leading to these smaller populations not being able to adapt to changing environments. This paper will be looking at how population size has no effect on genetic variety in a habitat generalist species, while a smaller population size in a habitat specialist species will have lower genetic variance.

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

Therefore, a combination of social, economic, and environmental factors together play an important role. One pillar alone cannot be the answer to solving the loss of biodiversity issue. A battle fought on all fronts is a battle won.

Biodiversity conservation is about protection the variation of life in our mother earth and keeping natural ecosystems functioning and healthy. Panasonic Corporation realizes the negative effect of their business activities to the biodiversity. Therefore, Panasonic Corporation initiative promotes the conservation of biodiversity in Products, Procurement and Land Use area.

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
