Re: Amphora optical sections

Hi Adam, Thank you for your comment. The diatom measures at 40x60 µm. I used DIC with a 40/0,95 apochromat Zeiss Jena objective, the microscope was setup for afocal projection with a 10/18 Kpl-W eyepiece (with a 40 mm pancake lens on a Canon 50D). The diatom was attached to the underside of the cov...

Amphora optical sections

I would like to share a small series of optical z-sections of an Amphora diatom that had attached to the underside of a floating coverslip. I decided not to stack as in this series of sections you can see different organelles such as the nucleus and chloroplasts in positions relative to each other. ...

Quite a nice finding and superb documentation. Btw you can directly embed the video here in the thread by placing the video ID within the youtube tags

e.g. the ID of your video is HaGDw2e6cBg and you put it [*youtube ]*here*[/youtube*] (without the asterisks)

Coleps feasting on a rotifer egg

Coleps is a genus of predatory ciliates that feed on bacteria, algae, other protists (dead and alive) as well as animal and plant tissues. Here you can see one Coleps specimen feeding on what I believe is a rotifer egg. If you look closely you can follow the path of egg particles making their way to...
