Kinds of Biodiversity

Genetic Diversity

Species Diversity

Ecosystem Diversity

Genetic diversity refers to the variety of genes within a species. Each species is made up of individualsthat have their own particular genetic composition.Within a species there may also be discrete populations with distinctive genes.

Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species' abundances. Species diversity is one component of the concept of biodiversity

Ecosystem diversity refers to the variety of ecosystems in a given place. Within any broader landscape there is a mosaic of interconnected ecosystems. To conserve biodiversity, conservation at the landscape level is critical.

Biodiversity and agriculture

Agricultural diversity can be divided into two categories :

Intraspecific Diversity, which includes the genetic variety within a single species.

Interspecific Diversity, refers to the number and types of different species.

Conservation of biodiversity

In situ conservation, means the natural or the original place. In situ

conservation includes National parks, Wildlife sanctuaries, Biosphere

reserves, etc.

Ex situ conservation

In situ conservation

situ conservation, plant and animal species are conserved outside

their natural habitats. gene banks, zoos, botanical gardens, culture

collections, etc.
