Very nice shots.

Just looked up your location. very nice place to live , plenty of creeks and waterways to explore.

Winter i guess to be a different matter.

Thank you

Superb quality images !
What setup do you use (microscope, objectives, camera) ?

Hi Marek
My set up
Nikon Optiphot 2 DIC, with universal condenser, Nikon CF160 objectives, Nikon 2.5 relay lens, Canon EOS Rebel T5i, post processing with ZereneStacker and GraphicConverter for Mac.
Offsetting the universal condenser does amazing oblique.

Forgive me, this is a really quite old thread (I dimly remember from my sister's youth discussing Japanese comics that there is some unforgivable crime called ''thread necromancy''!).

The photographs are beautiful, however, Spirotaenia might not actually be a desmid. It was always thought to be a saccoderm desmid (i.e. order Zygnematales family Mesotaeniaceae), but, to quote Algaebase ''recent studies suggest strongly that Spirotaenia is not related to Spirogyra and may not be part of the Zygnematophyceae but more related to Chlorokybus.'' which would put it near the base of the Chloroplastida [Viridiplantae].

It's thought it uniquely evolved conjugation separately from the Zygnematophyceae.

Of course, nothing is ever quite simple, and some believe that Spirotaenia is polyphyletic and should be redistributed to reflect that not all Spirotaenia-species are necessarily closely related to each other.

Ah, but by the standards of photomacrography.net, a thread is not "old" until multiple years have passed with no comment.

As I read the timestamps, this one is less than one month, so barely even "yesterday's news".

You have very interesting information about the phylogeny!
