The survival of humankind is also highly dependent on the ecological balance. Example: Saprophytes act as a decomposers, imagine if these saprophytes are not present in the ecosystem there will be no composting which will … The bacteria in the nitrogen cycle can perform better in such cases, thereby maintaining the ecological balance. gender identification for boosting date production . The evenness makes it bearable for the living organisms as well as plants to tackle the situation and fight it. As already mentioned, the presence of a broad range of organisms in an ecosystem is termed as diversity in species. The proposed index incorporates an importance weight to each species of organisms found in an ecosystem. So to make a more efficient, productive and sustainable ecosystem, it is important to maintain high species diversity. If a species disappears, an entire ecosystem can start to unravel. More diverse ecosystem tend to be more productive. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. He explains importance of Species Diversity to the Ecosystem. Biodiversity is important to most aspects of our lives. For example, in the Pacific Northwest, salmon holds together the entire ecosystem. 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. This study aims to characterize the forest communities and to identify and compare the plant species diversity in the study area. The number of species of both animals and plants have reduced in the ecosystem. Human well-being was measured as self-reported life-satisfaction and species diversity as the species richness of several taxonomic groups (e.g. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. Greater species … Diversity is important because first and foremost, it helps buffer environmental stresses on an ecosystem. Diversitycan be viewed in terms of both the number of species present in an ecological system and the extent to which some species are threatened and endangered. It shows various animals that thrive on this planet with their unique living conditions. To some extent, biodiversity merely offers a new, emotive,term for some older ideas and programs. birds, mammals and trees). The number of species present in an ecosystem refers to the evenness of a species. 1. It depicts heterogeneity that persists in nature. In: Henry, Robert J. Similarly, in our own previous work, we concluded that a few dominant species were important because they explained a large proportion of the variation in pollination between sites . Although positive relationships between vegetation-shaped habitat heterogeneity and animal species diversity are well documented on both local and regional scales (Davidowitz & Rosenzweig, 1998), empirical and theoretical studies have yielded contradictory results. . The abundance of individuals of a specific species in an environment indicates the richness of that species. Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. An abundance of species diversity prepares the environment for handling any catastrophe as it comes. We related socio-economic data from more than 26,000 European citizens across 26 countries with macroecological data on species diversity and nature characteristics for Europe. Measuring diversity: the importance of species similarity Tom Leinster 1,2∗ Christina A. Cobbold 1School of Mathematics and Statistics, University of Glasgow, UK 2Boyd Orr Centre for Population and Ecosystem Health, University of Glasgow, UK Abstract Realistic measures of biodiversity should reflect not only the relative abundances of species, but also the differences between them. In biodiversity, tropical forests play an important part and where they carry 90 per cent of the world’s species. Biologists estimate that species extinctions are currently 500–1000 times the normal, or background, rate seen previously in Earth’s history. Australia is renowned for its globally distinct ecosystems, made up of diverse flora and fauna. Fish species diversity is roughly divided equally between marine (oceanic) and freshwater ecosystems. A common measure of this variety, called species richness, is the count of species in an area. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. 1 Department of Entomology and Nematology, University . We value biodiversity for many reasons, some utilitarian, some intrinsic. Let us spell Biodiversity which will be (Bio+ diversity), Bio will be biological organism or living organism and diversity will be variability among organism. the ecosystem with a great variety of producer species will produce large biomass to support a greater variety of consumer species 2. The health of an ecological system can often be judged by its biological diversity and balance. Based on these results, this study argues that management actions for the protection of birds and the landscapes that support them would benefit humans. Healthy and solid biodiversity can recover from a variety of disasters. You might be well aware that living beings in an ecosystem are interdependent for food. Each species has a crucial role in ecosystem management . There have been five mass extinctions in the four-billion-year history of life on earth, Wilson explains, and we are now in the midst of the sixth great extinction, caused solely by human actions. By continuing you agree to the use of cookies. No need to prove that our living world is abounds with enormous biodiversity of living organisms. Species Diversity - A Comprehensive Analysis, Boost Your Exam Preparation with These Top Tips, Endemic Species - What are Endemic Species, Study of Tissues and Diversity in Shapes and Sizes of Plant and Animal Cells, Vedantu - S. 249-285 ISBN 0-85199-904-2 It depicts heterogeneity that persists in nature. The most important is the marine biodiversity which is highest in the Western Pacific. Ecologists have long questioned how this diversity is maintained. A new Importance-Diversity Index is proposed as an enhancement to the traditional Shannon’s diversity index. Species Diversity Impact Factor 2018-2019. In a healthy ecosystem, diverse and balanced number of species exist to maintain the balance of an ecosystem. Diversity plays an important role in providing a variety of diets for the organisms in the ecosystem. Ferris, Howard 1, and H. Tuomisto 2. This chemical diversity is important for humans because of the potential uses for these chemicals, such as medications. Ans. For example, A larger number of plant species means a greater variety of crops; Greater species diversity ensures natural sustainability for all life forms; Healthy ecosystems can better withstand and recover from a variety of disasters. The loss of individuals, populations, and species decreases the variety of genes—the material needed for species and populations to adapt to changing conditions or for new species to evolve. As a result, it creates a considerable amount of biomass which is a source of renewable energy. Why is species diversity important? Physics. The two main divisions are species richness and evenness. Importance of genetic diversity: Due to pollution, there may be adverse effects on some specific species and loss of fertility due to changes in genes. He explains importance of Species Diversity to the Ecosystem. Support your answer with the finding of Tilman. Diversity is important because first and foremost, it helps buffer environmental stresses on an ecosystem. There are no direct answers to such näive questions (importance of Species Diversity) but we can develop a proper perspective through an analogy (the ‘rivet popper hypothesis’) used by Stanford ecologist Paul Ehrlich.
