Species Diversity and recognition

Polar regions

Accounts for 2% of all species

Environments not as hospitable to many species

Temperate Environments

Accounts for 1/4 or 24% of all species

Lower rate of speciation than in tropics

Higher rate of extinction than in tropics

Overdifferentiation

One species linked to many different type of plant names/plants for a specific culture

May be due to different genotypes in which each different type gets own name

Tropical Environments

Accounts for 3/4 or 74% of all species

Has highest diversity for many reasons

Stable climate season to season

High percentage of solar energy captured

Low Extinction rates

High speciation rates

High degree of specialization

Elevation

Higher speciation in lower elevation

Underdifferentiation

Many species linked to one type of plant name/plant for another culture

The culture sees no difference among the plant
