blooming time, diatoms

Post by René »

Got a nice fresh sample in from a brackish harbour with a massive bloom of Coscinodiscus jonesianus var. commutatus, http://bibdigital.rjb.csic.es/ing/Libro.php?Libro=1006&Pagina=452

It is nowadays renamed Coscinodiscopsis commutata, due to the two strange buds on the edge of the valve. The function of these processes is unknown. There are still plenty of things left to discover :D

Best wishes, René

Lovely set with nice concentration of subject diatoms.
I also like the fact that one of them is tipped over allowing a side view, don't see that very often in diatom photographs. :D

Great set of images. Of all the things that fascinate me in nature (i.e. pretty much everything), diatoms are top of the pile. That sloppy, wet biology can consistently build such tiny, intricate and near-perfectly regular rigid glass structures is an utter wonder to me :shock:

Diatoms

Another thing about diatoms is that when you look at Diatomaceous Earth which is millions of years old, you recognize contmeporary species.

The side-on views are really informative, in addition to the great shots of the large faces. I have managed to get a member of this genus (or one similar looking one from fresh water) under a SEM once (was able to sneak a pond specimen into my semiconductor SEM for our open house...) and the pores were not nearly as uniform as I'd thought from looking at optical microscope images.
