Naegleria fowleri are thermophelic amoebae. They enter through the nasal passage and then infect the CNS of those who may dive into or swim in warm fresh waters, such as shallow lakes, ponds, some streams and rivers and poorly treated swimming pools. They are usually quite prolific when water temps....

Re: Microscope

I would recommend the Zeiss Axiostar. I have had one for years and it has been a great performer and trouble free.

Re: Pond Scum

The biodiversity in a single drop of pond water or "scum" is astounding. If one considers protozoa alone, there are over 50,000 species of protozoa with even more yet to be discovered. An excellent source of reference material would be Jahns, "how to know the Protozoa" Second Edi...

Re: What is this insect I found?

Be careful with or around these bugs. Their rostrum can inject a powerful tissue dissolving toxin, quite painful from what I can gather and if you happen to be allergic to bee stings, it can produce the same reaction thereof. In some species, they can release a stream of toxin from the rostrum, mayb...

This maybe of some help to you. http://ameba.i.hosei.ac.jp/DIB/Jenn04/index.html Protozoa are animals that no two people can agree on, or so it seems.

There are a number of ways to eliminate odors I guess. Charcoal filtering of the air at the source would be one. :)

Allow me to venture a guess. I would say that biomonitoring would be the observation and recording of data such as population decline or rise for example, taken from a specific organism or group of organisms that are known bio-indicatiors of the environment around them. Some of these would be Mayfly...

Here is an unusual tactic for bringing earthworms to the surface, especially in wooded areas. Select a small hardwood tree about three inches +/- .5 diameter. With a saw, cut the tree down leaving about four inches above the soil surface. Then take the saw and "lightly" saw the stump on to...

Take a rather large piece of cardboard, carpet, or an old rug even and soak it with water thoroughly. Place it on the ground, preferably in the shade of a tree or underneath the branches or on the ground along the northern side of your home. Usually by the next day or in a couple of days, you will h...
