I don’t know what these globules are, but I wish I did.

EDIT: Here is a useful comment:

With regard to those “globules” you had observed (and photographed), If they are not a type of aquatic/aero-aquatic fungus, then they most likely are Spotted Salamander spermatophores.   These are picked up by a female salamander, fertilized internally, and then in a few days she deposits them (as egg masses) on vegetation in a seasonal pool.  *And remember, along with that unique matrix covering them below water, they can often appear opaque in color, so quite different from Wood Frog egg masses.   Of course, both A Field Guide to the Animals of Vernal Pools by Kenney and Burne, and Vernal Pools: Natural History and Conservation by Colburn are terrific resources that will impart much, much more information.

A predaceous diving beetle. There were tons and tons of them. Every now and then one would climb out like this.

I don’t know what these are:

This terrible photo of a spider, maybe a dwarf spider, Erigoninae?

Tardigrades (and other beasts)   Leave a comment

In the past, I’ve been fooled (actually: I’ve fooled myself) into believing that I’ve found tardigrades, because I’ve wanted to find them pretty badly. This time, I’m sure, though.

I went to Moose Hill Mass Audubon and took three small samples home:

  1. Moss from a dead tree trunk
  2. Lichen attached to a piece of bark, lying on the ground
  3. Moss from the top of a medium sized rock

I added water and waited a couple of hours, then looked at them under my (rather poor quality, but excellent value for the money) Tomlov electronic microscope. Please don’t confuse this with a scanning electron microscope :-).

The first two samples were completely devoid and bereft of any animal life I could find. The third one, the moss from the top of the rock, for some reason was utterly chock full of life. It was difficult to find a field of view that didn’t have some animal or the other. I don’t understand the reason for the difference, the samples were from similar-ish samples, not far from each other. I don’t know if this is a systematic issue, but next time I go exploring, I know I’m going to definitely look at the rock moss.

We’ll get to the tardigrades, please be patient. First, a movie with a flatworm (planarian) on the lower left. There’s also a green blob on the lower right that I’m unable to identify any further than “green blob”.

Here’s a spectacularly transparent worm, which I think is some sort of Nematode worm:

Here’s another one that gives some idea of all the activity going on. There’s at least one planarian, one tardigrade (not the best view of it, though) and a bunch of other creatures that I can’t pin down.

There were a lot of good views of the tardigrades, which were very common. I’m going to just share one. It’s translucent, so you have to look a little carefully, at center-left. You can see that it’s the right size, shape, and you can see its (adorable little) lobopods (aka, legs).

Lake Massapoag ice   Leave a comment

Warm weather has been breaking up our ice cover on the lake. It’s a sunny day so I pointed toward the sun and cranked open the aperture to decrease the depth of focus. Unfortunately, I had my zoom, which doesn’t open up too wide, only up to f/5.6. This would have been better with a better lens.
