Desmids, Rotifers,Spirogyra and more from a Sphagnum Fen

Post by WalterD »

Today I want to show you a set of pictures as a result of a recent sampling trip. The location was a sphagnum fen and the water was very rich, one could easily find over 100 different organisms.
Not too many different desmids though, anyhow I selected 2 for this post.
Differential interference contrast (3,5), Darkfield (1), Fluorescence (2,6) and transmitted light (4); it was fun to try all of those.

1. Closterium lunula 25x oil
2. Closterium lunula 21x
3. Kellicottia bostoniensis 25x
4. Micraterias truncata 100x oil
5. Micraterias truncata 100x oil
6. Spirogyra 21x

Jacek, Carlos and Robert, thanks for your feedback.

I've added three more snapshots.

7. Dragonfly larva. Seen from the back but because it's transparant the mouth parts are also visible. I've combined all in this photo.

8. Bosmina Longisrostris. A small water flea with an elephant nose.

9. Dead Sphagnum with fluorescence, 21x objective.

I really like the Kellicottia bostoniensis but they're all excellent.

Thank you very much Jacek, Carlos and Smokedaddy.

Finally the water of the sample was replaced by fixative, in order to take pictures of the dragonfly larva. After that I also found a mosquito pupa in the sample. Was a bit in doubt whether or not to post it because the lighting (darkfield combined with a Jansjö led lamp) was far from ideal. The other picture shows the pupa in fluorescence, and the last one a detail of the "trumpet"

Regards,
Walter
