The rate of endemism with the lower latitude:
- increases.
- is constant.
- falls.
The natural occurrence of endemic species is:
- limited to certain territories
- limited only to Australia.
- limited only to Europe.
Endemism is often caused by:
- geographic and temporal isolation.
- lack of nutrients.
- the excess of nutrients and water.
In the Czech Republic we can often find:
- neoendemits.
- paleoendemits.
- euroendemits.
Currently in the Czech Republic there are about:
- 80 endemic species and subendemic species.
- 60 endemic species and subendemic species.
- 20 endemic species and subendemic species.
Subendemic species are:
- species with the vast majority of sites in our area.
- species with predominantly minority locations in our area.
- species with the occurrence only in our country.
Neoendemits came into existence:
- during Quaternary (period).
- during the Tertiary period.
- now.
Areas rife with endemic species are in:
- Madagascar.
- Sicily.
- Great Britain.
Relicts are:
- taxa, whose recent occurence is the rest of the former, much larger territory.
- taxa, whose recent occurence is the rest of the former, much smaller territory.
- taxa, whose recent occurence is the center of the former territory.
The frequent cause of the relicts was:
- cooling of the climate in connection with the onset of ice ages.
- cooling of the climate in connection with the onset of ice ages and climate warming after the Ice Age.
- climate warming associated with the greenhouse effect.
