Re: I bought some slides from John!
Pat I am sure you will be really pleased with John B's slides. For your further consideration let me suggest a great book: A Color Atlas of Plant Structure e by Bryan Bowes. I bought a used one a few of years ago and it has really improved my knowledge of what I am observing. Plus, between it and J...

I bought some slides from John!
Last week I bought some slides from John and I'm really looking forward to receiving them from England. I expect I'll be especially challenged in photographing them as I typically don't work with botanical specimens; the stacking will be most fun and interesting I suspect. And so now John's shipment...

Re: Spider mites!
I came across this old post of mine. And I have to say -- The stupid mites are back. I sprayed the plant down again last night and I can only hope that will take care of it. Does anyone here happen to know the life cycle of spider mites? I suspect that I got rid of the adults but not the eggs. Oddly...

I just watched a video of these guys on Youtube and it seems the wider end is the head end, although they do have flexibility and they sort of ooz about like an amoeba to some extent.

That is a really great video. I've never come across one of these in the wild so I've not seen one in action before. The movements are very interesting and I really like how you captured so much detail with your video. Thanks!

Re: The very weirdest thing I've yet seen
I agree with John -- You did it again! I've never seen anything like that -- It reminds me of the Spanish Dancer nudibranch I saw in a documentary of ocean life. I too have no idea what this might be but I will watch this thread closely.

Re: Not sure, Schistosoma?
As I understand it, these guys don't live very long outside a host -- Is that correct? Incorrect. Schistosome adults are never found outside the host. They reside within the mesenteric veins of the host, where they will release eggs into the host circulation. The eggs are the only products that lea...

Re: Not sure, Schistosoma?
Looks like a fibre, to me. An unstained trematode should appear brownish or grey. I believe the red schistosomes you see in textbooks have been prepared with stains (acid carmine, or something similar). Trematodes are amazing, if you can find them! I've encountered the cercaria stage, in water cont...

I don't think it would be nearly as big a deal as my brain wants me think it is. Right now ...

Re: Found in the RSW lake

I think what we're looking at is indeed a rotifer, but someone else will have to come up with the species. The first copepod I believe is a nauplius, or a baby (larva) copepod -- Perhaps a cyclops.

Re: A stylonchia
There are many different ciliates that crawl with cirri in the spirotrich class. Stylonychia is still a legitimate type, but they and their closer relatives are not nearly so compact. I think this is probably Euplotes , which are generally more oval and often have grooves; for freshwater kinds they...

Re: Was looking for bacteria, not sure if I found any
I could be wrong (of course) but I think those little things in the background, just out of focus, are bacteria. Typically, they are around 4-8 microns long (although of course some are quite a bit larger or smaller than that). So, to see them individually you need to use 400x magnification or even ...

This is one of the very first photos I took when I got my microscope awhile ago. I didn't think much of it at the time, but on a second viewing it really doesn't seem all that bad after all.

Re: Stacking Software
From my limited stacking experience I would say you won't lose any resolution if you downsize the images somewhat before stacking. One would think that from 8 images one would necessarily get a higher resolved image than from 1 image, but this is only the case if you have very finely spaced steps. ...

The thing is you can't really be sure what you're going to find in any given moment. I saw my first ever paramecium in the wild just last month and I've only ever seen one waterbear. What I do see rather consistently are nematodes, rotifers and bacteria. The types of protists and other animals will ...
