Importance/Significance of biodiversity: Ø Biodiversity indicates variations of life forms (species, ecosystem, biome) Ø Biodiversity indicate the health of ecosystem The term biodiversity (from the phrase “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life. It is the number of different species of plants, animals, and microorganisms. Ecosystem function is important for supporting plant and animal communities, and ensuring the long-term survival of human populations. Biodiversity is categorized into species diversity, genetic diversity and ecosystem diversity. Wild food sources are mainly aquatic, but few are being managed for sustainability. The Gulf Coast of Florida is another unique ecosystem with different characteristics. To learn more about biodiversity, visit the Australian Museum website or read about it on Wikipedia. Learning Objectives. Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity. While heavy machinery keeps spraying #monocrops with #pesticides and #fertilizers, millions of #family #farmers are applying agroecological approaches to redress those impacts and revive #rural areas. 3. All forms of life from microbes to plants to humans contain genes. California has prairies, deserts, lakes, forests and beach. If a population is minimized and must cross-pollinate or inbreed with the survivors, successive generations will have fewer different genes and it is most often the case that susceptibilities are magnified and reduced infertility occurs, so that smaller populations carry illnesses or crippling enough defects that they soon die out. Importance of Biodiversity. A food web is a more complex arrangement where some of the species have a couple different food options. Millions of species inhabit land, freshwater, and ocean ecosystems. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Wilson, the noted biologist and author who coined the term “biodiversity,” explains it as “the very stuff of life.” For at least 3.8 billion years, a complex web of life has been evolving on Earth. Benefits of Biodiversity to the Ecosystem . Ecological diversity within an ecosystem is more diverse when it contains varied topography, allowing more places for shelter and for escape, a lot of sunlight and rainfall, allowing for more rapid growth of plants as a food source and stable temperatures, making adaptation easier for species. Provide more medicinal resources and pharmaceutical drugs. For example, biodiversity can occur in a very small aquarium where there are few small fish or can occur in a large ocean where whales and sharks like huge fish live with other aquatic animals. Biodiversity also benefits the humans in numerous aspects. Support a larger number of plant species and, therefore, a greater variety of crops. 17 December, 2019 0 Comments "Tourism and Importance of Biodiversity . The earth itself has ecosystem diversity: for example, it has forests, oceans, deserts, wetlands and grasslands. The biosphere, the totality of life is a membrane of organisms wrapped around the earth so thin that it cannot be seen edgewise from the space shuttle. Ecosystems affect the biosphere, or life on earth. Species diversity then is the number of different species co-existing within a community, for example bear, humans, birds and dogs. This project is no longer funded and will not be updated. This includes the deep feeling of being interconnected with other species on earth. A wider range of genetic diversity allows species to build resistances to diseases, as shown in studies on leaf-cutting ant colonies and fruit flies, and strengthens the possibility that at least some individuals will survive, and by making them less susceptible to inherited disorders. We also need to protect our water resources, protecting soil & maintaining eco-balance. The Pacific Northwest represents a unique ecosystem. Or a dominant species could be an invasive plant that will overtake the native plants in the competition for soil. Sustainability is the ability of the ecosystem to maintain its ecological processes, the composting of debris into soil, the exchange of carbon and air, the production of rainfall, photosynthesis, the life-giving processes required to maintain life as we know it on earth. Since rainforests have huge ranges of plants, many insects or animals will have more diverse preys. They also provide food, shade, construction material, medicines, and fiber for clothing and paper. When we talk about ecosystem and biodiversity we need to focus both bio and non-bio (physical) factors. An analysis on the importance of biodiversity in an ecosystem as shown by the gray wolf extirpation and reintroduction in Yellowstone Park The extirpation of the grey wolf (Canis lupus) in Yellowstone Pak is a prime example of the impact of biodiversity loss, specifically a keystone species, on a terrestrial ecosystem. Plants, for instance, help humans by giving off oxygen. Preserving biodiversity at any level may not seem like a big deal -- at first. Ø This value is related primarily with functions of ecosystem. For example, an ecosystem being studied may be as small as a patch of lichen on a rock or patch of moss on a tree trunk or it could be an entire coral reef and all of the life that it sustains and that sustain it . They keep plants, fish, and animals fed. Its aquatic life may contribute to the quality of the soil by aerating it and enriching it with its waste and carcasses. If a fire tears through a forest where only one species exists and is wiped out by the fire, the forest ecosystem is less likely to deal with this loss than if only one out of 20 species disappeared. Biodiversity is important for maintaining an important balance of the ecosystem. Healthy ecosystems and rich biodiversity: How do we replace lost biodiversity? Some economic and social arguments further illustrate the importance of biodiversity: Inland water biodiversity is critically important to poverty reduction and the achievement of human development targets. Nutrition and biodiversity are linked at many levels: the ecosystem, with food production as an ecosystem service; the species in the ecosystem and the genetic diversity w… Loss of biodiversity may have reverberating consequences on ecosystems because of the complex interrelations among species. Genetic erosion of crops is an issue of concern today. All species, including humans, are adversely affected by the loss of species diversity. Genes are the bits of biochemical information that partly determine how an organism looks, behaves, and live… It may have cattails that filter and clean the water. It is commonly believed that the more diversity of life within an ecosystem the stronger it is and the better able it is to sustain itself in the face of external stresses. The more links in the food chain there are, like more fish for the bear, the healthier everyone up the chain can be. The importance of biodiversity for numerous industries across Australia has not been quantified, but recent issues exemplify our ongoing reliance on functioning ecosystems to maintain key processes that, in the past, may have been taken for granted. Likewise, it is well-documented that nature contributes to the emotional well-being of humans . For example, our ecosystem services such as pollution breakdown and absorption and protection of water resources. Biodiversity is important in ecosystems because it prevents extinction of species, allows organisms to adapt to changes in the environment and provides a wide range of materials and foods for survival. Generally, a species is a group of similar individuals capable of interbreeding and producing offspring. If our ecosystems fail, if too many species become extinct or disabled from performing their functions, then humans will not be able to survive on earth. Diversity is important for species in order to maintain resilience against unexpected events, such as sudden climate changes or natural disasters, like forest fires or floods. Human life relies on our ecosystems providing the life-sustaining services of providing oxygen, detoxifying our soil and water, providing materials for clothing and shelter and providing our food and the nutrients we require. This study evaluates the importance of biodiversity for multiple ecosystem functions in a tropical human‐modified landscape. High biodiversity in an ecosystem, that is a large variety of species and genes in the ecosystem contribute to a stronger ecosystem. A study of ecosystem diversity looks at these different ecosystems within the region and considers their sustainability, their impact on the surrounding environment and possibly even their impact on human existence. Living organisms on the earth are complex, dynamic, and varies according to the earthly or the marine ecosystems. Biodiversity is defined as "the variety of life and it's processes," which can be thought of as the diverse and richness of life that exists on earth. An excellent article. There are multiple examples within any region of each category of insect, bacteria, herbivore, omnivore or carnivorous predator. Biodiversity is important for a few reasons. Many of our most potent medicines are derived from plants . Antibiotics, fungicides, anticancer drugs, blood-clotting agents and thinners, anesthetics, cardiac regulators and fever suppressants are among the drugs we have obtained from wild biodiversity . The more links that exist in the web the more stable the ecosystem as the removal of one link will not have a dramatic effect if there are other links that can fill the void. And yet it is so complex that most of the species within it, close to 90 percent , remain undiscovered. Economic Benefits of Biodiversity . Our biodiversity is very important to the well-being of our planet. Concerned about the rapidly increasing loss of genetic diversity the UN Food and Agricultural Organization supports a trust of diverse seed collections around the world to maintain food security. Before getting into Tourism and Biodiversity, it is crucial to know what is tourism and Bio-diversity. The largest scale of biodiversity generally examined is ecosystem diversity. Given the interconnected nature of ecosystems, where a change in one area can have far reaching effects elsewhere, it is therefore vital to maintain as great a variety of species as possible in order to ensure the continued healthy existence of the planet.
