Koliko vrst diatomej živi na planetu?<br />
Ne vemo. Morda milijon ali<br />
dva, doslej pa je znanih več kot<br />
deset tisoč morskih in sladkovodnih<br />
vrst. Toda znanstveniki se<br />
še sprašujejo, kaj sploh je vrsta<br />
diatomeje, saj je šele elektronski<br />
mikroskop omogočil vpogled v<br />
drobne strukture njihovih kremenastih<br />
ogrodij, značilnih za posamezne<br />
vrste.<br />
Vsak dan opisujejo nove oblike,<br />
nove strukture in podrobnosti —<br />
in zato nove vrste.<br />
How many diatom species live on<br />
our planet? The truth is we don’t<br />
know. It may be one or two millions;<br />
till now, about ten thousands<br />
of salt– and freshwater species are<br />
known. Scientists are still trying to<br />
understand what a diatom species<br />
is, as only electronic microscopy has<br />
enabled the insight into tiny structures<br />
of silica frustules characteristic<br />
for single species.<br />
Every day, new forms, structures<br />
and details are discovered — therefore<br />
also new diatom species.<br />
