Objective
To impart knowledge and awareness about the evolution mechanism, strength, status, environmental significance, utilization and conservation of biological diversity

Theory

UNIT I
Biodiversity- an overview; level and scale of biodiversity – genetic, species and ecosystem diversity, alpha, beta and gamma diversity; origin of life, organic evolution; genesis of biodiversity; biodiversity changes in space and time; speciation and isolation mechanism.

UNIT II

UNIT IV
Genetic erosion and loss of biodiversity – causes and criteria of genetic erosion, levels of genetic erosion; global climate change and loss of  biodiversity; biodiversity, bio-productivity and sustainability; biodiversity and life security - food, health, environment and job security

UNIT V
