I think that high biodiversity is necessary for maintaining various ecosystem functions and services because when diversity allows for functions and services to take place. For example, in an ecosystem where there is less diverse, the organisms in that community are more susceptible to disease and are less resilient to disasters. Therefore, when there is less diversity the community will be less likely to be proactive in the community for functions like decomposition and nutrient cycling. Also, more diverse communities are more likely to include organisms that are very efficient at doing certain functions.
A study I found, Perspectives on the link between ecosystem services and biodiversity: the assessment of the nursery function, talks about the relations between biodiversity and ecosystem services. They reviewed the role of nursery habitats and how they help keep biodiversity in the habitat and the services they supply. In the article it states, “Biodiversity and ecosystem functioning are influenced by interactions between individuals or species which direly rely on habitat availability and condition.” I believe this is in correlation with my statement about communities that are more diverse also are more resilient. If the habitat can hold all of the biodiversity, it must be in good condition and the more diverse an ecosystem is, the more able those organisms are to survive in it.
The article also stated, “Biodiversity is the variety of life, including variation among gens, species, ecosystems and habitats.” Therefore, if an ecosystem lacks biodiversity, then the likelihood of that ecosystem producing services and functions for people is low. This article talks a lot about how these functions and services help humans so much ...

... this topic quite a bit in ecology, but briefly mentioned dilution effect in this course. I thought the dilution effect model was very interesting. Basically what the dilution effect model says is that if there are more species in an ecosystem, there are less health problems. For example, when we talk about the spread of Lyme disease in forest, if there is high diversity in the forest then there are lower rates of Lyme disease because there are more other mammals that are not harbors of Lyme disease. Therefore, when these other mammals get bit by a tick with Lyme disease, it does not infect them and there are less deer being infected, thus leading to less infections all together. I thought this was a cool concept because it works like this in any ecosystem. This is the reason why the more species living in an ecosystem makes the system stronger as a whole community.

Biodiversity: How Ecological Systems Link Us Together Essay

- Biodiversity is the unit of variation of life. It can refer to genetic variation, species variation, or ecosystem variation which seems to be the result of the warm climate and high primary productivity. Biodiversity usually tends to bunch in hotspots, and the number has been growing through time but will be likely to slow in the future. According to Lemons and Morgan (1995) study the biological diversity defines as “the variability among living organisms from all sources and ecological complex of which they are a part; this includes diversity within species, between species and of ecosystems’’....   [tags: species variation, ecosystem, life]

Essay on Pollination, Biodiversity & Ecosystem Services

- The pollen is constituted by a multitude of microscopic granules contained in the pollen sacs of the anthers of flowers and has the appearance of a powder, coloured differently depending on the flower. These granules are the male reproductive cells of the plant. This powder is easily carried by the wind and can reach the female organs of the flowers, the pistils. The other way of pollination than that of pollen dispersal is the fertilization of flowers, when it is given by bees and other pollinators....   [tags: powder, bees, ecosystems]

Biodiversity Essay

- Biodiversity Imagine this: you step outside and feel the barren, rough, red Earth beneath your feet. There’s not a single plant in sight—no rustling of the leaves, no mighty towering trees to block the severe winds, and the scorching heat of the sun searing upon your face because there’s no shade. And when you take a whiff of air, you feel nothing filling up the space inside your lungs, liberating your body’s activities. What’s wrong with this picture. It’s not possible, of course. Even though plants aren’t the building blocks of life, they’re pretty close and without them, most of life wouldn’t exist—YOU wouldn’t exist....   [tags: plants extinction ecosystem]
