Diatomeje so svetovljanke, zato<br />
težko govorimo o ogroženosti vrst<br />
ali skupin.<br />
Toda previdno! Posamezne vrste<br />
žive le v določenih vodnih habitatih.<br />
Če jih prizadenemo, onesnažimo<br />
ali uničimo, izginejo tudi<br />
zanje značilne drobcene alge. In<br />
kisika je manj!<br />
Zato je vrstni sestav skupaj s pogostostjo<br />
vrst kremenastih alg uveljavljen<br />
kazalnik kakovosti in zdravja<br />
vodnega okolja.<br />
Diatoms are cosmopolites; therefore<br />
it is very difficult to talk about<br />
endangered species or groups.<br />
But with caution! Single species only<br />
live in specific aquatic habitats. If<br />
degraded, polluted or destroyed, also<br />
the tiny algae characteristic for these<br />
habitats will disappear. This would<br />
be a loss of oxygen!<br />
Therefore, the structure of algae<br />
community along with species frequency<br />
is an important indicator<br />
of quality and health of aquatic<br />
environment.<br />
