Enquiring
Minds Want to Know -
Worm, who art thou?
|
 |
| There are more
than 15,000 species of known nematodes, many many more that are
unclassified. Thousands can be find in any handful of soil, sometimes
in your local drinking fountain. An individual may contain up to 27
million eggs, and "lay" 200,000 in a day. Nematodes cause
so many interesting diseases, ranging from pinworms to
elephantaisis in humans, and root-knot and ear cockle in crops.
Clearly, there is a lot of integrative biology to learn from them...
much more than their "model" system status implies!
One recent article addressed the ecology of C.
elegans, concluding: "Although [C. elegans] has
traditionally been considered a soil nematode, we could not find it
in soil but frequently recovered it from snails."

Quote of the day
-
"You have
made your way from worm to man, and much within you is still
worm."

Nematodes in the
News
UIUC
researchers have been studying nematode-caused diseases in one of the
world's more endangered monkeys in Uganda. Read more ...

Hypersea, and the
nematode in you
"The land
ecosystem, in spite of its relative youth, outstrips the marine
ecosystem in terms of greater primary productivity and species
diversity per unit area. This occurs because land eukaryotes actively
direct the flow of nutrient-rich fluids. The body fluids of land
eukaryotes have had a significant evolutionary and geochemical
impact, and we here refer to these fluids, and the organisms through
which they flow, as Hypersea."
Biosystems.

Don't forget the
Songs!
Wherever
scientists do field work or peer down a microscope, thoughts may
drift. The world of the nematologist is no different. Check out the
Nematode
