Conserving Biodiversity
International Efforts For Conserving Biodiversity - The earth summit held in 1992 at Rio de Janeiro resulted in a convention on biodiversity, which came into force on 29 t h December 1993. The key objectives of the conservation are: i) Conservation of biological diversity..
Levels of Biodiversity
It refers to the variation of genes within a species. The genetic diversity enables a population to adapt to its environment and to respond to natural selection. The amount of genetic variation is the basis of speciation. Genetic diversity wit..

Gradients of Biodiversity
Biodiversity varies with change in latitude or altitude. The diversity increases as we move from high to low latitudes (i.e., from poles of equator). In the temperate region, the climate is severe with short growing period for plants while in tropical rain forests the conditions..

Gene Mutation - The variations at the level of the gene which form the basis of the differences between related organism as well as the diversity among organisms is called gene mutation. Gene mutation is defined as a sudden discrete change in the genetic material of gene which i..
Forests and Wild Life
The biotic component of our environment on land, i.e. plants and animals (leaving aside the oceans and other water bodies) are overwhelmingly found in forests. Forests form a buffer for the earth to protect life forms; in fact that's where all our biodiversity and including cultivated cr..
