endemic taxa
they have the natural range limited only to a territory on a limited areathey are not found outside that territory Slide3
restricted area(range)
it has a different scalesome species known as European endemic species such as Abies

Endemic taxa
the presence of endemic species in the flora of the area is most often associated with:geological isolation eg. in the mountains or on islands temporal
isolation
Slide5
steno-endemic species
species with small areas eg. an island, a mountain range or a single locationSlide6
The rate of
endemismit increases with the lower latitude - the closer to the equator, the more endemic taxa in these areasSlide7
Neoendemits
time is very important hereall endemic species in the Czech Republic are considered NEOENDEMITS and they arose during the QuaternarySlide8
Paleoendemits
according to the evolutionary theory older species are known as PALEOENDEMITSearlier
species with a larger area, which dwindled
in
the
course
of
timeSlide9
Endemic species
currently in the Czech Republic there are about 80 endemic species and subendemic species (species with the vast majority of sites in our area)the largest
representation of endemic species
is
in the Giant Mountains (more than 20) Slide10
relicts
taxa whose simultaneous occurrence represents the remainder of an earlier, much larger expansionSlide11
Relicts
reducing areas of these taxa was mostly due to strong cooling of the climate in connection with the onset of ice agesSlide12
Relicts
the most famous relict from the last ice age is Rubus chamame mulberries, which grows in our republic
only
on the peat bogs in the Giant Mountains
,
whereas
in northern Europe
it
is
a common type with
the
continuous
growthSlide13
Worksheets - revision
Which taxa are known as endemic species?Explain the terms: euryendemics, steno-endemic species, relicts.What is the impact of the rate of endemism on the latitude?Are there any endemic species and relicts in the Czech Republic?Slide14
