Biodiversity is both essential for our existence and intrinsically valuable in its own right. As ecologists studied biodiversity in the environment, they observed a regular pattern in which diversity was distributed over the entire area of the planet. Biodiversity is defined as the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems. The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers.. PPT OF BIODIVERSITY Tusharkanti Nayak. What are the different types of biodiversity? biodiversity and combating climate change. With the majority of the world’s population residing in cities, and with this number anticipated to grow substantially, understanding the patterns and drivers of urban diversity is crucial. The ultimate measure of biodiversity is the total number of species in existence. Some types are landscape ecology, population ecology, and behavioral ecology. To be good, food needs to be responsibly sourced and consumed, as well as healthy. For CPR organizations, green is the new black. The study of biodiversity encompasses the dis-covery, description, and analysis of the elements that un-derlie these patterns as well as the patterns themselves. Consumptive use value 6. The EU contributes to halting the global loss of biodiversity through conservation efforts within its own territory as well as at the global level. In these cases, we used a … 14.2 Patterns in Biodiversity Species are not uniformly distributed over the Earth; diversity varies greatly from place to place. A.

Over the last century, population, market pressures and the development of new agricultural technologies have encouraged patterns of agricultural development tending towards agricultural intensification (i.e. strongly related to biodiversity measures than to patterns of resource consumption or agricultural potential. SKU: £3.50. Biological diversity is not evenly distributed across the Earth; certain latitudes, ecosystems, and regions contain more diversity than others. This does not mean that other levels of biodiversity, such as gene diversity within species, do not exist or are not important, but just that the key level of focus is the species. 1. Ecology is the branch of science that examines the relationships organisms have to each other and to their environment.Scientists who study those relationships are called ecologists. Global Patterns of Biodiversity • main factors determining species richness • also increased with the need to understand how biodiversity might change – under different scenarios of global climate change jitenderanduat@gmail.com 4. 7. Oil pollution and its recovery Rachana Tiwari. The The Tree of Life the All-species Foundation and the All-species Inventory are efforts to use the World Wide Web to coordinate the efforts of hundreds of biologists to classify and describe species. Further sea-level rise and melting of snow and ice are likely as Earth warms. This is a fully editable PowerPoint presentation designed specifically for the new Edexcel A Level Biology B Specification for first teaching in 2015. Darwin* noticed three distinctive patterns of biological diversity: (1) Species vary globally, … In this unit we will see how diversity changes through succession, genetic diversity, limiting factors and human activities. and overcome severe biodiversity decline and local extinction of sensitive species by this Eco Bridge/Wildlife Corridor. • 2objectives: Reduce environmental stress on human health and Indo-Burma: Includes entire North-eastern India, except Assam and Andaman group of Islands (and Myanmar, Thailand, Vietnam, Laos, Cambodia and southern China) What Is the Difference Between "Climate Change" and "Global Warming"? Species Biodiversity Species Diversity is the effective number of different species that are represented in a collection of individuals 6. One way of conceptualizing the structure of a science is that at any time it contains ontologies, theories, and values (Kuhn 1962; Lakatos 1976; Laudan 1978, 1986). Google Scholar Wilson MV and Shmida A (1984) Measuring beta diversity with presence-absence data. Ecologists discovered two broad kinds of diversity patterns, namely: However, it has 8.1 % of the global species diversity. Although these patterns are increasingly well documented, understanding why they exist constitutes one of the most significant intellectual challenges to ecologists and biogeographers. As an integrative factor with respect to microevolutionary Neo-Darwinian processes, mass extinctions are probably due to a set of different possible causes (basaltic super-eruptions, impacts of … Biodiversity is the variety of all life forms on earth - the different plants, animals and micro-organisms and the ecosystems of which they are a part. (Secretariat, 2000) Biodiversity involves diversity of genes within a species, of species within ecosystems, and of ecosystems in the biosphere (Frequently, 2005). The course Patterns in Biodiversity consists of three modules: 1. The ability to both understand and quantify biodiversity is important to conservation efforts. Mass extinctions are a major pattern in macroevolution. How biodiversity is measured? Global biodiversity losses provide an immediate impetus to elucidate the relationships between biodiversity, productivity and stability. Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-20th century, and its projected continuation. To maintain life-supporting systems and essential ecological processes. Global patterns of terrestrial vertebrate diversity analysed in the study. Each of the 32 bioregions is coloured by its vertebrate species richness (amphibian, reptile, bird, mammal richness combined; dark green represents the lowest values and dark red represents the highest values) (Jetz & Fine, 2012) The importance of this definition is that it draws attention to the many dimensions of biodiversity. Sustainable utilization of species and ecosystem. So there is an urgent need to model the response of biodiversity on the intensity of threat and the species' ecological attributes. IEEP’s Marianne Kettunen explores the EU’s external biodiversity policy, arguing the need for a more coherent framework and effective implementation – and making the policy integral to EU’s action on SDGs at the global level. Biodiversity is the foundation for all ecosystem services. 2. £3.50.

The warming climate likely will cause more floods, droughts and heat waves. The Ecology, Biodiversity, and Conservation series presents balanced, comprehensive, up-to-date, and critical reviews of selected topics within the sciences of ecology and conservation biology, both botanical and zoological, and both 'pure' and 'applied'. 5% of the world’s species biodiversity . Global pattern of biodiversity Pranavathiyani G. Climate Stuart Kirkham. is a cool-season pulse grown in winter cropping cycle in South Asia and provides a major source of nutrition for many low-income households. In this study, we quantified the effects of species richness and species combination on the productivity and stability of phytoplankton communities subject to predation by a single rotifer species. Let’s consider a simplified example of the biodiversity within a tropical rainforest ecosystem . Ecosystem Services 4. 3. The ecologists studied biodiversity in the environment and observed a regular pattern in which diversity was distributed over the entire area of the planet. Because of their frequency, quickness and global effects, they shaped the global biodiversity several times during the geological ages. (Classification, Measurement & Importance of Biodiversity PPT) What is biodiversity? Himalaya: Includes the entire Indian Himalayan region (and that falling in Pakistan, Tibet, Nepal, Bhutan, China and Myanmar) 2. A Level Biology - Classification and Biodiversity Presentation. Biodiversity is not evenly distributed on the planet. Global biodiversity hotspots • A biodiversity hotspot is a region with a high level of endemic species. It is the number of different species of plants, animals, and microorganisms. Introduction to Biodiversity PPT. For indigenous peoples, forest-dwellers, fisherfolk and others who rely To a first approximation, the distribution of biodiversity across the Earth can be described in terms of a relatively small number of broad-scale spatial patterns. Fuller el al., 2007 ), yet these benefits do not necessarily increase with greater natural vegetative area. The dimensions of biodiversity and its relationships to human well-being have been extensively addressed by Levin (2000), including both the services that biodiversity supports and the evolutionary genesis of biodiversity together with the ecological processes underlying patterns and trends. Ecosystems worldwide are increasingly threatened by human activities, including climate change and the degradation and fragmentation of natural habitats. the importance of crossing the roads by the animals. (2008) 35, 1337–1348 Biodiversity and Macroecology Group, Department of Animal and Plant Sciences, University of Sheffield, Sheffield S10 2TN, UK (e-mail: k.j.gaston@sheffield.ac.uk) To a first approximation, the distribution of biodiversity across the Earth can be described in terms of a relatively small number of broad-scale spatial patterns. Although everyone depends on ecosystem services, some people depend on them more closely than others. Biodiversity conservation is the protection and management of biodiversity to obtain resources for sustainable development. Biodiversity conservation has three main objectives: To preserve the diversity of species. Customer Code: Creating a Company Customers Love HubSpot. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity). Every species on Earth is related to every other species through genetic connections. Declines often show strong phylogenetic and ecological patterns. Will biodiversity loss in our forests influence key ecosystem services like the breakdown of organic matter and cycling of nutrients around the planet? As all the organisms […] Biodiversity, or biological diversity, is the variety of all species on earth. This is especially in light of how cities are moving from grey to green infrastructure. The long term biodiversity conservation in the Chilean winter rainfall - valdivian forests are up to the government, the private sector, and individual citizens cooperation. Biodiversity is higher near the coasts because of great variety of producers, habitats, and nursery areas. Resources, Biodiversity and Habitat, Productive Natural Resources, and Sustainable Energy. It covers the whole of Topic 3 which is Classification and Biodiversity. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. Biodiversity, or Biological Diversity, is the sum of all the different species of plants, animals, fungi and microbial organisms that live on Earth, including the various ecosystems in which they live on.

Threats to Aquatic Biodiversity Threats to Freshwater Species 20% of freshwater fishes extinct or in serious decline Extinct/at-risk salmon/steelhead runs outnumber healthy by 3:1 In CA, 57% of fish species are extinct or declining (Moyle and Williams) Aquatic species worse-off than terrestrial It is the result of evolution, natural processes, and human influence. BIODIVERSITY BIOLOGICAL DIVERSITY or BIODIVERSITY is part of nature which include the differences in genes among the individual of a species ; the variety & richness of all the plant & animal species at different scales in space –locally ,in a region ,in country & the world ;& the … For many group of animals or plants, there are interesting patterns in diversity, the most well- known being the latitudinal gradient in diversity. In order to maximize diversity, it makes sense to try to preserve groups from throughout the tree of life, rather than large numbers from one branch. BIODIVERSITY - DEFINITION The number and variety of plants, animals and other organisms that exist in an ecosystem is known as biodiversity It is a measure of the variety of organisms present in different ecosystems The richness of biodiversity depends on the climatic conditions and area of the region ' Biodiversity is the result of 3.5 billion years of evolution 2 The Roadmap states that the Commission will assess how best to limit waste throughout the food supply chain, and consider ways to lower the environmental impact of food production and consumption patterns, via a Communication on Sustainable Food, in 2013. forms, and functional roles, organized in spatial patterns from biological communities to ecosystems, regions, and beyond. In addition attention will be paid to philosophical and societal aspects of biodiversity. There are still quite a number of species that are yet to be discovered. Biodiversity is the variety observed in organisms at every level of biological organization. Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns.Continued overexploitation can lead to the destruction of the resource. Ecological Concepts, Principles and Application to Conservation. Global Biodiversity: Patterns and Processes - Global Biodiversity: Patterns and Processes Biodiversity is the diversity which exists in the biological realm, either locally or over the globe. They both have potentially devastating impacts on our environment, health and economy. BIODIVERSITY PRESENTEDBY: AkhilMadankar asmadankar@gmail.com 2. If we decide that we want to maximize biodiversity, then the phylogenetic patterns produced by systematists give us a way to prioritize areas based upon the diversity they contain. Biodiversity BC has prepared two key science documents, a report on Ecological Concepts, Principles and Application to Conservation and Taking Nature's Pulse: The Status of Biodiversity in British Columbia.These reports are designed to support action and planning by providing a primer on biodiversity (setting out the … By fully understanding the declines we can make projections to inform policy. The greatest marine biodiversity occurs in coral reefs, estuaries, and on the deep-sea ocean floor. As an estimate, there are around 45,000 species of plants and about 90,000-1,00,000 species of animals. There are several factors that influence how many species a given ecosystem supports and these factors lead to predictable patterns of diversity across the globe. Introduction to Biodiversity PPT.

Aesthetic Value. 4 • The Pacific Island Countries (PICs) have limited resources (land & water) , biosecurity capacities and more vulnerable to the;-impact of climate change-globalisation of trade and market uncertainties, -and the spread of introduced weeds, pests and diseases, and invasive species. However, species do not all respond equally to these threats. Regional Training Workshop on Adaptation for the Pacific Least Developed Countries, In terms of the number of basic kinds of organism and number of species of each kind, biodiversity has varied markedly through geological time; and, in terms of present day species richness, biodiversity varies greatly between one part of the earth and another. In this entry, we explore questions regarding the ontology, theoretical structure, and values central to conservation biology. Cambridge University Press, Cambridge, pp 319–336 CrossRef Google Scholar Eriksson BK, Sieben K, Eklöf J, Ljunggren L, Olsson J et al (2011) Effects of altered offshore food webs on coastal ecosystems emphasize the need for cross-ecosystem management. When looking deeper we find it is more related to the consumption patterns that affect usage of resources and therefore it is consumption patterns that invariably affect how much the environment gets degraded. Biodiversity is the degree of variation of life. Cataloging the biodiversity on Earth is a huge team effort. The loss of populations, species, or groups of species from an ecosystem can upset its normal function and disrupt these ecological services. Environmental Value 2. Biodiversity underlies everything from food production to medical research. Patterns of Biodiversity (i) Latitudinal gradients : The diversity of plants and animals is not uniform throughout the world but shows a rather uneven distribution. India is one of the twelve mega biodiversity countries of the world. By the end of the century, climate change and its impacts may be the dominant direct driver of biodiversity loss and changes in ecosystem services globally. A recent consideration of different ways of assessing biodiversity concluded that species richness, while not perfect, is the best metric (Maclaurin and Sterelny 2008). In media, it is synomonous with the term "climate change. Introduction course: Biodiversity in the Dutch landscapes This three weeks introduction starts with the theme of the minor and an introduction to all the different modules of the minor. Given, the obvious risk of loss of diversity, it is increasingly necessary to take actions concerning preservation, in which safety features are necessary for measuring the variation of diversity in space and time. Biodiversity is the term that is given to describe the variety of life on earth and the natural patterns it forms. CONTENTS 1. Introduction 2. Concept of Biodiversity and its types 3.

It explicitly recognizes that Every organism depends on living and non-living things to survive. understanding how the loss of biodiversity affects the functioning of ecosystems and thus affects society. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet. Genetic Biodiversity Genetic diversity, the level of biodiversity refers to the total number of genetic characteristics in the genetic makeup of a species. Patterns of Biodiversity. Biodiversity can be identified in a variety of forms, including species diversity, habitat diversity and genetic diversity. Lentil (Lens culinaris Medik.) Journal of Biogeography (J. The heat waves may get hotter, and hurricanes may get stronger. Tropics have more species than temperate or polar areas. Healthy ecosystems regulate floods,absorb greenhouse gases and protect us from increasingly extreme weather patterns and they are therefore vital to help us reduce and adapt to the impact of The following is a list of some of the benefits, or services, of biodiversity: 1. Many hypotheses have been proposed by scientists to explain greater diversity in the tropics. in favor of biodiversity: If we can protect and connect a network of lands and waters that encompass the widest possible range of abiotic factors, this range of available habitats should continue to promote a high diversity of species, and provide a complement and safety-net to traditional species- and habitat-focused approaches. ADVERTISEMENTS: Biodiversity, besides its ecological significance provides a socio-economic and monetary asset to the nation. Using the formula in Cooper & Hedges (1994), variances for effect sizes were estimated.Then a weighted average effect size T for a fixed effect model and the homogeneity test statistic Q were calculated as in Cooper & Hedges (1994).If Q was significant, effect sizes were heterogeneous and differed among the included studies. per item. Taking Nature’s Pulse concluded that of the six major stresses that threaten biodiversity in BC, the three most significant ones are ecosystem conversion, ecosystem degradation and alien species. While dams provided the majority of the country’s electricity, they can have destructive environmental and social consequences, such as affecting previously healthy rivers, disrupting wildlife and … However, the relative importance of these factors varies widely among the world’s biogeographical realms. Biodiversity and endemism is high in Australia because: It is big (with 70,000km continental coastline, 8.6 million km2 continental marine territory; 16.1 million km2 oceanic jurisdiction). 3.1 Introduction to Biodiversity. River ecosystems (riverscapes) encompass ecological, social, and economic processes (ecosystem functions) that interconnect organisms (ecosystem structure), including humans, over some time period. Scientists estimate that more than 10 million different species inhabit Earth. Precipitation patterns have changed spatially and temporally, and global average sea level rose 0.1–0.2 meters ( S7.ES ). ADVERTISEMENTS: Biodiversity, besides its ecological significance provides a socio-economic and monetary asset to the nation.

Populations and species are disappearing due to disturbances in the environment caused by human activities. BIODIVERSITY & ITS TYPES 1. Biodiversity Pattern in Species Biodiversity is the variety observed in organisms at every level of biological organization. As ecologists studied biodiversity in the environment, they observed a regular pattern in which diversity was distributed over the entire area of the planet. It has only 2.4 % of the land area in the world. Biodiversity and Conservation 5: 649–669. Lentil productivity is perceived to be sensitive to high rainfall, but few studies document spatial and temporal patterns of yield variation across climate, soil, and agronomic gradients. Biodiversity also includes the genetic information that these organisms contain. Biodiversity is the amount of variety of life on Earth. 4 The degradation and loss of biodiversity often result from and reinforce existing patterns of discrimination. Paleontological data for the diversity of marine animals and land plants are shown to correlate significantly with a concurrent measure of stable carbon isotope fractionation for approximately the last 400 million years.

Lake Victoria contained almost 500 species of cichlids (just one family of fishes that are present in the lake) before the introduction of an exotic species in the 1980s and 1990s caused a mass extinction. Biodiversity is the sum of all the different species of animals, plants, fungi and microbial organisms living on Earth and the variety of habitats in which they live. Aesthetic Value. 4 • The Pacific Island Countries (PICs) have limited resources (land & water) , biosecurity capacities and more vulnerable to the;-impact of climate change-globalisation of trade and market uncertainties, -and the spread of introduced weeds, pests and diseases, and invasive species. However, species do not all respond equally to these threats. Regional Training Workshop on Adaptation for the Pacific Least Developed Countries, In terms of the number of basic kinds of organism and number of species of each kind, biodiversity has varied markedly through geological time; and, in terms of present day species richness, biodiversity varies greatly between one part of the earth and another. In this entry, we explore questions regarding the ontology, theoretical structure, and values central to conservation biology. Cambridge University Press, Cambridge, pp 319–336 CrossRef Google Scholar Eriksson BK, Sieben K, Eklöf J, Ljunggren L, Olsson J et al (2011) Effects of altered offshore food webs on coastal ecosystems emphasize the need for cross-ecosystem management. When looking deeper we find it is more related to the consumption patterns that affect usage of resources and therefore it is consumption patterns that invariably affect how much the environment gets degraded. Biodiversity is the degree of variation of life. Cataloging the biodiversity on Earth is a huge team effort. The loss of populations, species, or groups of species from an ecosystem can upset its normal function and disrupt these ecological services. Environmental Value 2. Biodiversity underlies everything from food production to medical research. Patterns of Biodiversity (i) Latitudinal gradients : The diversity of plants and animals is not uniform throughout the world but shows a rather uneven distribution. India is one of the twelve mega biodiversity countries of the world. By the end of the century, climate change and its impacts may be the dominant direct driver of biodiversity loss and changes in ecosystem services globally. A recent consideration of different ways of assessing biodiversity concluded that species richness, while not perfect, is the best metric (Maclaurin and Sterelny 2008). In media, it is synomonous with the term "climate change. Introduction course: Biodiversity in the Dutch landscapes This three weeks introduction starts with the theme of the minor and an introduction to all the different modules of the minor. Given, the obvious risk of loss of diversity, it is increasingly necessary to take actions concerning preservation, in which safety features are necessary for measuring the variation of diversity in space and time. Biodiversity is the term that is given to describe the variety of life on earth and the natural patterns it forms. CONTENTS 1. Introduction 2. Concept of Biodiversity and its types 3.

It explicitly recognizes that Every organism depends on living and non-living things to survive. understanding how the loss of biodiversity affects the functioning of ecosystems and thus affects society. This can refer to genetic variation, species variation, or ecosystem variation within an area, biome, or planet. Genetic Biodiversity Genetic diversity, the level of biodiversity refers to the total number of genetic characteristics in the genetic makeup of a species. Patterns of Biodiversity. Biodiversity can be identified in a variety of forms, including species diversity, habitat diversity and genetic diversity. Lentil (Lens culinaris Medik.) Journal of Biogeography (J. The heat waves may get hotter, and hurricanes may get stronger. Tropics have more species than temperate or polar areas. Healthy ecosystems regulate floods,absorb greenhouse gases and protect us from increasingly extreme weather patterns and they are therefore vital to help us reduce and adapt to the impact of The following is a list of some of the benefits, or services, of biodiversity: 1. Many hypotheses have been proposed by scientists to explain greater diversity in the tropics. in favor of biodiversity: If we can protect and connect a network of lands and waters that encompass the widest possible range of abiotic factors, this range of available habitats should continue to promote a high diversity of species, and provide a complement and safety-net to traditional species- and habitat-focused approaches. ADVERTISEMENTS: Biodiversity, besides its ecological significance provides a socio-economic and monetary asset to the nation. Using the formula in Cooper & Hedges (1994), variances for effect sizes were estimated.Then a weighted average effect size T for a fixed effect model and the homogeneity test statistic Q were calculated as in Cooper & Hedges (1994).If Q was significant, effect sizes were heterogeneous and differed among the included studies. per item. Taking Nature’s Pulse concluded that of the six major stresses that threaten biodiversity in BC, the three most significant ones are ecosystem conversion, ecosystem degradation and alien species. While dams provided the majority of the country’s electricity, they can have destructive environmental and social consequences, such as affecting previously healthy rivers, disrupting wildlife and … However, the relative importance of these factors varies widely among the world’s biogeographical realms. Biodiversity and endemism is high in Australia because: It is big (with 70,000km continental coastline, 8.6 million km2 continental marine territory; 16.1 million km2 oceanic jurisdiction). 3.1 Introduction to Biodiversity. River ecosystems (riverscapes) encompass ecological, social, and economic processes (ecosystem functions) that interconnect organisms (ecosystem structure), including humans, over some time period. Scientists estimate that more than 10 million different species inhabit Earth. Precipitation patterns have changed spatially and temporally, and global average sea level rose 0.1–0.2 meters ( S7.ES ). ADVERTISEMENTS: Biodiversity, besides its ecological significance provides a socio-economic and monetary asset to the nation. Biodiversity plays an important role in the way ecosystems function and in the services they provide. Biogeogr.) In: Ormond R, Gage J, Angel M (eds) Marine biodiversity, patterns and processes. Unavailable. The challenge of quantifying patterns of diversity at the 2. Ethical and Moral Value 8. Birds offer the most cost-effective system towards understanding global loss of biodiversity, biodiversity hotspots and the effects of climate change on ecological systems. Economic Value 5. Water Nidhi D. What to Upload to SlideShare SlideShare. Biodiversity is the most precious gift of nature mankind is blessed with. 1 INTRODUCTION. Populations and species are disappearing due to disturbances in the environment caused by human activities. BIODIVERSITY & ITS TYPES 1. Biodiversity Pattern in Species Biodiversity is the variety observed in organisms at every level of biological organization. As ecologists studied biodiversity in the environment, they observed a regular pattern in which diversity was distributed over the entire area of the planet. It has only 2.4 % of the land area in the world. Biodiversity and Conservation 5: 649–669. Lentil productivity is perceived to be sensitive to high rainfall, but few studies document spatial and temporal patterns of yield variation across climate, soil, and agronomic gradients. Biodiversity also includes the genetic information that these organisms contain. Biodiversity is the amount of variety of life on Earth. 4 The degradation and loss of biodiversity often result from and reinforce existing patterns of discrimination. Paleontological data for the diversity of marine animals and land plants are shown to correlate significantly with a concurrent measure of stable carbon isotope fractionation for approximately the last 400 million years. Conservation Biology. where m=n org +n conv – 2. It is the different plants, animals and micro-organisms, their genes, and the terrestrial, marine and freshwater ecosystems of which they are a part. Recent declines in honeybee populations may Biodiversity also supplies indirect services to humans which are often taken for granted.
