Species Diversity and recognition

Underdifferentiation

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

The culture sees no difference
among the plant

Elevation

Higher speciation in
lower elevation

Tropical Environments

Accounts for 3/4 or 74%
of all species

Has highest diversity for many reasons

High degree of
specialization

High speciation
rates

Low Extinction
rates

High percentage of
solar energy captured

Stable climate
season to season

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

Temperate Environments

Accounts for 1/4 or 24%
of all species

Higher rate of extinction
than in tropics

Lower rate of speciation
than in tropics

Polar regions

Accounts for 2%
of all species

Environments not
as hospitable to
many species
