What Is Biodiversity Project

What is biodiversity? Oh, the beauty of a forest! The pleasure of walking through it, enjoying the smells of the flowers and the wild; watching the insects flitting about and listening to the birds chirp - how we all love it and wish to return to it again and again. It is this biodiversity that we have to protect and take care of in order to enjoy the joy of it all. But what is biodiversity? Biodiversity is the variety and differences among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part. This includes genetic diversity within and between species and of ecosystems. Thus, in essence, biodiversity represents all life. India is one of the mega biodiversity centres in the world and has two of the world's 18 ‘biodiversity hotspots’ located in the Western Ghats and in the Eastern Himalayas (Myers 1999). The forest cover in these areas is very dense and diverse and of pristine beauty, and incredible biodiversity. According to an MoEF Report (1996), the country is estimated to have over 45,000 plant species and 81,000 animal species representing 7% of the world’s flora and 6.5% of its fauna. The 1999 figures are 49,219 plant species representing 12.5% and 81,251 animal species representing 6.6%. The sacred groves of India are some of the areas in the country where the richness of biodiversity has been well preserved. The Thar desert and the Himalayas are two regions rich in biodiversity in India. There are 89 national parks and 504 wildlife sanctuaries in the country, the Chilika Lake being one of them. This lake is also an important wetland area. Learn more through map on biodiversity in India. Over the last century, a great deal of damage has been done to the biodiversity existing on the earth. Increasing human population, increasing consumption levels, and decreasing efficiency of use of our resources are some of the causes that have led to overexploitation and manipulation of ecosystems. Trade in wildlife, such as rhino horn, has led to the extinction of species. Consequences of biodiversity loss can be great as any disturbance to one species gives rise to imbalance in others. In this the exotic species have a role to play. To prevent such loss, the Government of India is setting up biosphere reserves in different parts of the country. These are multipurpose protected areas to preserve the genetic diversity in different ecosystems. Till 1999, ten biosphere reserves had been set up, namely Nilgiri, Nandadevi, Nakrek, Great Nicobar, Gulf of Mannar, Manas, Sunderbans, Similipal, and Dibru Saikhowa. A number of NGOs are being involved in the programme to create awareness. But legal protection is provided only to national parks and sanctuaries, which cover about 4.5% of India’s land area.

Definitions The most straightforward definition is "variation of life at all levels of biological organization".[3] A second definition holds that biodiversity is a measure of the relative diversity among organisms present in different ecosystems. "Diversity" in this definition includes diversity within a species and among species, and comparative diversity among ecosystems.

A third definition that is often used by ecologists is the "totality of genes, species, and ecosystems of a region". An advantage of this definition is that it seems to describe most circumstances and present a unified view of the traditional three levels at which biodiversity has been identified:

NEED OF BIODIVERSITY Biological diversity is important because of the way relationships between species and habitats combine to provide yet more variation in the living world. Any human activity that diminishes this 'bio - diversity' could therefore impoverish our own quality of life, reduce the resources available to us and ultimately jeopardise the survival of our descendants. We should seek to conserve biodiversity because: it confers direct benefits as natural processes protect our planet it provides the raw material of food, clothing and medicines it enhances our quality of life, by adding variety to our surroundings it helps shape our culture and inspires our poets, painters, writers and composers ➢ it is heritage we should not deny to the next generation ➢ it is affected enomously by what we do. ➢ ➢ ➢ ➢ ➢

PROJECT SCOPE- Biodiversity in Grain and Graze (BiGG) Alan House The erosion of biodiversity in agricultural landscapes is a global phenomenon. Two approaches have been proposed to deal with this issue – the practise of wildlife-friendly farming, where critical components of biodiversity and ecological function at a landscape scale are supported within the agricultural landscape; and intensification of production on the most productive parts of the landscape so that other land can be “spared” for conservation. Both approaches have benefits and disbenefits for both production and conservation. Our project is designed to test the notion that the gradient of intensification of production, from grazed native woodlands through pastures based on native grasses to pastures of exotic species and finally cropped areas, will result in altered communities of plants and animals in a predictable way. This project is designed to answer the questions: • does the introduction of pasture phases in cropping rotations have biodiversity and ecosystem services benefits? • does pasture type and management (grazing, length of phase etc) influence biota? • do pasture phases represent an additional habitat for wildlife that augments farmleve biodiversity? • is local landscape context important in determining patterns of richness and diversity?

We are using a functionally important subset of biodiversity (ground active and soil/litter invertebrates) to investigate these hypotheses. Three mixed farms (Tara, Qld; Bogabilla, NSW; Warialda, NSW) that represent contrasting environments and pasture/cropping combinations in the Border Rivers region, were chosen for study. All comprise a mix of: remnant native woodland; pastures based on native grasslands or of native grasses but derived from open woodland or clearing; pastures based on exotic grasses; and cropping. At each farm, replicates of each land use type (remnant woodland, native pastures, sown pastures) on each farm are being sampled for ground active and canopy (forage height) invertebrates using pitfall trapping and suction sampling. Vegetation composition and structure is also recorded. Invertebrates are sorted to Order level, with selected groups (ants initially, spiders and beetles subsequently) to species where possible. THE IMPORTANCE OF BIODIVERSITY At the ecosystem level, biodiversity provides the conditions and drives the processes that sustain the global economy – and our very survival as a species. The benefits and services provided by ecosystems include: >> Generation of soils and maintenance of soil quality The activities of microbial and animal species – including bacteria, algae, fungi, mites, millipedes and worms – condition soils, break down organic matter, and release essential nutrients to plants. These processes play a key role in the cycling of such crucial elements as nitrogen, carbon and phosphorous between the living and non-living parts of the biosphere. >> Maintenance of air quality Plant species purify the air and regulate the composition of the atmosphere, recycling vital oxygen and filtering harmful particles resulting from industrial activities. >> Maintenance of water quality Wetland ecosystems (swamps, marshes, etc.) absorb and recycle essential nutrients, treat sewage, and cleanse wastes. In estuaries, molluscs remove nutrients from the water, helping to prevent nutrient over-enrichment and its attendant problems, such as eutrophication arising from fertilizer run-off. Trees and forest soils purify water as it flows through forest ecosystems. In preventing soils from being washed away, forests also prevent the harmful siltation of rivers and reservoirs that may arise from erosion and landslides.

>> Pest control Around 99 per cent of potential crop pests are controlled by a variety of other organisms, including insects, birds and fungi. These natural pesticides are in many ways superior to their artificial equivalents, since pests can often develop resistance to chemical controls. >> Detoxification and decomposition of wastes Some 130 billion metric tons of organic waste is processed every year by earth’s decomposing organisms. Many industrial wastes, including detergents, oils, acids and paper, are also detoxified and decomposed by the activities of living things. In soils, the end product of these processes – a range of simple inorganic chemicals – is returned to plants as nutrients. Higher (vascular) plants can themselves serve to remove harmful substances from groundwater. >> Pollination and crop production Many flowering plants rely on the activities of various animal species – bees, butterflies, bats, birds, etc. – to help them reproduce through the transportation of pollen. More than one-third of humanity’s food crops depend on this process of natural pollination. Many animal species have evolved to perform an additional function in plant reproduction through the dispersal of seeds. >> Climate stabilization Plant tissues and other organic materials within land and ocean ecosystems act as repositories of carbon, helping to slow the build-up of atmospheric carbon dioxide, and thus contributing to climate stabilization. Ecosystems also exert direct influences on regional and local weather patterns. Moisture released into the atmosphere by rainforests, for example, causes regular rainstorms, limiting water loss from the region and helping to control the surface temperature. In cold climates, meanwhile, forests act as insulators and as windbreaks, helping to mitigate the impacts of freezing temperatures. >> Prevention and mitigation of natural disasters Forests and grasslands protect landscapes against erosion, nutrient loss, and landslides through the binding action of roots. Ecosystems bordering regularly flooding rivers (floodplain forests and wetlands) help to absorb excess water and thus reduce the damage caused by floods. Certain coastal ecosystems (salt marshes, mangrove forests, etc.) prevent the erosion of coastlines.

OBJECT ADDRESSING the ongoing loss of biodiversity and accelerating biodiversity surveys requires improvements in taxonomic information management, especially for the most numerous group - insects. Currently there are only scattered entomological biodiversity databases available. Internet, and its World Wide Web (WWW) protocol for distributed multimedia hyperdocuments, provide an efficient meta-model of how information on biological webs and taxonomies can be organised. Moreover, object-oriented modelling provides the tools for modelling complex biological domains such as taxonomy and biological field data realistically. We demonstrate a combination of object-oriented databases and WWW front-ends for managing taxonomic biodiversity information. One WWW page for each taxon, which is dynamically connected to the taxonomic hierarchy, allows users to manage taxonomic information efficiently. The pages and their summaries are created on demand out of the contents of the database. We argue that a new generation of WWW servers with special object-oriented modelling capabilities should be created for managing taxonomic information globally and on a distributed basis. The total number of species on Earth has been estimated to be in the magnitude of 10^7 [1], of which 1.7 million is known. Loss of this biological diversity currently runs at 10^3 times of its natural pace [2], eradicating 10^4 species per year. Hence, over the next 30 years, 10^6 species are bound to disappear even before they become known. Currently, 10^4 new species are discovered annually; a rate which has not changed during the past 15 years [1] despite an overall increase in scientific publishing. Insects comprise more than a half of all the species, and also the majority of the loss. There is obviously an urgent need to accelerate biodiversity surveys, especially in the area of tropical entomology. Molecular biology has enjoyed such services through GenBank [3] and EMBL Data Library [4] already since the early 1980's. Bringing GenBank databases to a distributed structure and public access reduced the backlog of data entries from 2 years to a few days [5], [6]. Use of on-line databases is now the norm in molecular biology. Taxonomic databases are also succeeding for plants. International Organization for Plant Information (IOPI) is constructing

a world plant check-list and database [7]. Its Taxonomic Databases Working Group has prepared a set of standards by which the different IOPI sites operate. Another case in point is the Biodiversity Information Network /Agenda 21 (BIN21) which is a special interest network [8] in the Internet that aims at organising biodiversity information into a network of distributed, public domain databases [9]. If BIN21 succeeds, it will bring the rest of bioinformatics to the level of molecular genetics in information management. However, there are no universally accepted data models nor publicly available database applications, which has caused delays in this critical area and incurred further costs to many institutions. In the following, we present the results of our experiments aiming at an architecture and an application suite for taxonomic biodiversity management in the Internet.
