Pond life on Duckweed

Here are some critters that were living on the edges of some Duckweed. Thriving at the surface of still ponds, Duckweed in a haven for many different types of micro life.

Thanks

Some nice images Frez.

I like the first one the best. The second looks like you swiped it off an "O"scope.

If I am not mistaken it appears as though you can see the nucleus of the algae in between the filiamnets.

Nice call on the nucleus. I hadn't seen it. Stalked cilates and other moving objects are a problem for the DP10. It just can't stop motion fast enough for a clear image and does't have provisions to sync with a flash.

Hi Frez,

I love the first one too. It should be a Gomphonema, isn't it? Really beuatiful colours.

Hi Bernhard

Yes, those are Gomphonema. The red is caused by EPI fluorescence. By using strong filters from the transmitted source, I am able to create a balance between the two. Here is the same specimen with a different transmitted filter.

Wonderful Frez. I particularly like the shots with the "balanced" transmitted/EPI-fluor combinations. Too often with EPI-fluor the context of what you are seeing can sometimes be confusing... but this works great.
