What is Biodiversity? • TOTALITY OF BIODIVERSITY ON EARTH FROM ECOSYSTEMS TO SPECIES AND GENES. • BIODIVERSITY SERVICES FOR HUMAN WELFARE. • MAINTAINS HEALTHY EARTH.
IMPORTANCE OF TAXONOMY • TAXONOMIC TOOLS ARE USED FOR THE • FOUNDATIONS OF BIODIVERSITY. THE HOUSE OF BIOLOGICAL SCIENCE IS MEANINGLESS JUMBLE WITHOUT THE BRICKS OF TAXONOMY AND FINE TUNED WITH SYSTEMATICS.
Hierarchical Levels in Biodiversity • Taxonomic diversity • • Kingdoms Phyla Families Genera Species Subspecies Populations Individuals • • • Ecological diversity Biomes Ecosystems Habitats Populations • Genetic diversity v • • • Populations Individuals Chromosomes Genes Nucleotides
DIFFERENT TYPES OF BIODIVERSITY • Alpha diversity: The total number of species • • coexisting in a region. Beta diversity: As habitats change along climatic and topographic gradients, new species turnover takes place. Gamma diversity: High species turn-over rate with distances between sites of similar habitats.

INDIA’S AGRO BIODIVERSITY • INDIA IS A MEGA DIVERSITY COUNTRY • • FOR “AGRO BIODIVERSITY” 167 CROP SPECIES AND WILD RELATIVES CENTRE OF ORIGIN 30, O 00 -50, 000 VARIETIES OF RICE, PIGEON-PEA, MANGO, TURMERIC, GINGER, SUGARCANE, GOOSEBERRIES.
WHAT ARE MICROORGANISMS • ORGANISMS MICROSCOPIC IN DIAMENSIONS, • • INCLUDES VIRUSES, BACTERIA, ALGAE, FUNGI AND PROTOZOA. UNITED STATES PATENT OFFICE INCLUDES PLANT AND ANIMAL CELLS BESIDES VIRUSES, BACTERIA, FUNGI AND PROTOZOA. MICROBES ARE PATENTABLE AS PER WTO AND INDIAN PATENT LAWS.

BIODIVERSITY ISSUES AND PROFILES • • • IDENTIFICATIONS QUANTIFICATIONS DISTRIBUTIONS ENDEMISM “HOTSPOTS “ AND “WARM SPOTS”
WHAT ARE “HOTSPOTS” • AREAS HAVING RICH ENDEMISM AND ARE FACING EXTREME THREAT PERCEPTIOINS • HOTSPOT AREAS OCCUPY ABOUT 8% OF WORLD GEOGRAPHICAL AREA BUT HOLD 46% TOTAL WORLD SPECIES. • INCLUDES MAJOR TROPICAL FORESTS , RELICT TEMPERATE MEDITERRANEAN ECOSYSTEMS.
HOTSPOTS VERSUS AGROBIODIVERSITY • HOTSPOT CENTRES DO NOT INCLUDE MAJOR AND VAVILOVIAN CENTRES OF ORIGIN AND DO NOT ENCOMPASS MAJOR AGROBIODIVERSITY ECOSYSTEMS OF THE WORLD. • AS A PARADIGM “HOTSPOT” CONCEPT HELPS CONSERVATION OF ENDEMIC AND THREATENED TROPICAL ECOSYSTEMS AND DOES NOT PROTECT AGROBIODIVERSITY. • THE DRIVING FORCE FOR THE EVOLUTION AND DOMESTICATION OF WILD SPECIES TOOK PLACE IN THE DEFORESTED WOODLANDS AND GRASSLANDS THROUGH HUMAN INTERVENTION AND ENVIRONMENTAL DETERMINISM.
BIODIVERSITY “HOTSPOTS” • • • TROPICAL ANDES MEDITERRANEAN MADAGASCAR, INDIA N OCEAN ISLDS. MESOAMERICAN FORESTS CARRIBBEAN ISLS. INDO-BURMAN • • ATLANTIC FOREST PHILIPPINES CAPE REGION E. HIMALAYAS SUNDALAND BRAZILIAN CERRADO S. W. AUSTRALIA

WHAT ARE “WARM SPOTS” • AREAS HOLDING VAST GENETIC RESOURCES, PREDOMESTICATES, AGRO-PASTURAL WOODLANDS AND GRASSLANDS WHICH ARE MODIFIED OR CO-EVOLVED WITH MAN’S DETERMINISM AND ENVIRONMENTAL STRESSES. • THESE WARM SPOT AREAS ARE IN OR ADJACENT TO THE CRADLES OF HUMAN CIVILISATIONS.
SEARCHABLE DATA BASES • BIODIVERSITY IS A DEAD CAPITAL UNLESS IT IS • • • SUSTAINABLY UTILISED. DATA GATHERING IS TO BE FOCUSSED FOR A SPECIFIC ACTIVITY OR FOCUSED GROUP, OR TARGETED TAXA. THERE SHOULD BE STANDARDISATION AND UNIFORMITY. DATA ARE TO BE COMPUTER COMPATIBLE FORMAT.
CHECK LIST FOR SPECIES OR FOCAL TAXA • • • LOCAL NAME SCIENTIFIC NAME PERSON GIVING INFORMATION LITERATURE REFERENCES LOCAL NAMES OF VARIETIES OF DOMESTICATED PLANTS AND ANIMALS. TAXONOMIC SPECIES GROUPS LANGUAGES USED LOCAL VALUE MAJOR USES AND MAJOR DISUSES
FOCAL TAXA STATUS AND MANAGEMENT • LOCAL NAME OF SPECIES OR SPECIES GROUPS. • HABITAT • CURRENT LEVELS OF ABUNDANCE (ABSENT; RARE; • • MODERATELY COMMON; ABUDANT) TRENDS AND REASONS BEHIND. TRENDS IN ABUNDANCE OR RARITY DURING LAST TEN YEARS: (Substantial increase; moderate increase; Little or no change; moderate decrease; substantial decrease) Immediate reason or motivation. Change in goods and services.
Essentials of data base for Medicinal plants: I • • Screening and collation of data for secondary metabolites: Indole alkaloids (Apocynaceae, Loganiaceae, Rubiaceae) Tropane alkaloids ( Solanaceae; Convolvulaceae) Benzylisoquinoline alkaloids ( Ranales or Magnolidae) Aporhine, Morhine (Beriberidaceae. Papaveraceae, Menispermaceae, Magnoliaceae) Polyacetylenes ( Asteraceae, Apiaceae) Terpenes ( Asteraceae, Apiaceae) Limonoids and Qassinoids ( Rutaceae, Meliaceae and Simaroubaceae)
ESSENTIALS OF DATA BASE FOR MEDICINAL PLANTS: • GLUCOSINOLATES OR MUSTARD OIL • • GLUCOSIDES ( BRASSICACEAE, CAPPARACEAE, MORINGACEAE) CYANOGENIC GLYCOSIDES (ROSACEAE, FABACEAE AND SAPINDACEAE 0 TERPENES ( ESSENTIAL OILS) STEROIDS (CARDIAC STEROIDS) FLAVONOIDS.
DATA BASES • • • FLORA AND FAUNA MONOGRAPHS REVISIONS INDICES AND BIBLIOGRAPHIES HERBARIA AND MUSEUM
TYPES OF DATA BASES • ON LINE IDENTIFICATIONS • INTERACTIVE KEYS • ENVIRONMENTAL RESOURCES INFORMATION • • NETWORK (ERIN) INTERNATIONAL LEGUME DATA BASE INFORMATION SERVICE (ILDIS) NATURE PRODUCT ALERT (NAPRALERT)
GENOMIC DATA AND SEQUENCES • AMINO ACID SEQUENCES • NUCLIOTIDE SEQUENCES • GENE LINKED CHARACTERISATIONS
PACKING OF CHARACTERS IN GENOMES • A BACTERIAL CELL OF ONE MICROMETRE (1 um, one • • millionth of a metre) PACKS ITS DNA MOLECULE ONE THOUSAND TIMES LONGER THAN ITS SIZE. In Human beings chromsomes(46 chromosomes in a human cell) total length in a cell if arranged end to end is about O. 3 mm. long) and the total DNA it contains, if arranged end to end would be about 2 metres in length. ). The packing is of the order of 10, 000 times. ) Hence of characters in a data assembly is unimaginably large.
