Biodiversity

Biodiversity

The number of and variety of species and ecosystems on earth.

Genetic diversity

Variety of genes and traits available within a species. The genetic variability among organisms, usually referring to individuals of the same species.

Species diversity

Variety of species within an ecosystem. A measure of diversity that takes into account. The quantity of each species present, as well as the vanity of different species present.

Ecosystem Diversity

Variety of ecosystem and habitat types in an area of land and water.

Species

All organisms capable of breeding freely with each other under natural conditions.

Hybridization

The crossbreeding of two different species.

Morphology

The physical appearance and characteristics of an organism; also, the science of the study of these physical characteristics.

Evolutionary change

A change that occurs in an entire population; usually occurs over a long period of time.

Structural diversity (aka environmental diversity)

The range of physical shapes and sizes within a habitat or ecosystem.

Food supply (Species Interactions)

Complex relationships exist between species and their food. Ex. Bone worms food on whale bones.

Protection (Species Interactions)

Many species depend on others for shelter and protection. Ex. Ants live in Cecropia trees.

Transportation (Species Interactions)

Many species move from place to place with the help of other species. Ex. Seeds with hooks “burrs”

Reproduction (Species Interactions)

Many species depend on other for successful reproduction. Ex. Tree cavities made by birds for nests woodpeckers.

Digestion (Species Interactions)

Species living within digestive tracts are essential for the digestion of food. Ex. Bacteria in human intestines.

Hygiene (Species Interactions)

Some species help maintain the health of another species. Ex. Small fish and shrimp remove parasites from big fish.
