Desmids from Austria

Post by Wolfgang Bettighofer »

Recently I've got a sample from sphagnum ponds of alpine region of Austria. There are lots of desmids and I'm working to combine manually pictures because contrast is too weak for software-stacking. In this case I also unsed manual stitching because this banana was too long for the 63/1.4 objective. But only this objective shows precisely the surface structure of Closterium costata, i. e. the longitudinal stripes. You see also transversal stripes. Each of these indicates a cell division, so this Specimen had 11 divisions.

Closterium bears star shaped chloroplasts with pyrenoid bodies in the center. This picture showes the pyrenoid layer (axial circular structures).

I just had to reply to your posting Wolfgang.

Amazingly "substantial" images showing so much great detail (especially pic1). Worth every bit your effort in expertly stitching and stacking 24 frames :shock:

These are images that demand you spend time really "looking" at the detail.


Bruce :D

I have to agree and Closterium has to be one of my favorite desmids. The thermal juggling of molecules associated with the Brownian Movement in the tips has always fascinate me. Great shots, rich color, and fantastic details, beautiful :D
