Topic: Mesenchytraeus solifugus


  
  glacier ice worms taxonomy mesenchytraeus solifugus
Mesenchytraeus as a genus is distinguished by its prominent penial bulb, the position of its head pore, and the structure of the nephridia (Goodman 1971:5).
After interviewing dozens of highly experienced mountaineers and naturalists, and not a single one having ever heard of a ‘snow worm’ (and all had seen ice worms), and because Welch tends to be an extreme ‘splitter’, I believe this species does not in reality exist.
It is very possible that the specimens were ground or stream-inhabiting Mesenchytraeus (or even glacier ice worms) that were fortuitously collected from snowpack; or perhaps the ranger who collected them just noted the locational context incorrectly.

Distribution and phylogeny of glacier ice worms (Mesenchytraeus solifugus and Mesenchytraeus solifugus rainierensis)
Glacier ice worms, Mesenchytraeus solifugus (Emery, 1898) and Mesenchytraeus solifugus rainierensis Welch, 1916 (Enchytraeidae), are the only known oligochaetes adapted to life in ice.
Our results suggest that the mechanism of ice worm dispersal is primarily active, though at least one episode of passive dispersal is noted at the southern extent of their range.

This amazing worm lives in glaciers, and its survival mechanisms are not well understood.

More complete sampling, both temporally and spatially, must be conducted in order to create adequate taxa lists for the purposes of ecological or biodiversity evaluation.
These taxa have been preliminarily identified as including ice worms (Mesenchytraeus solifugus Emery 1898) (Figure 5); and several kinds of springtails (Collembola, Isotoma (Myopia) n.
One additional species of springtails (referred to here as “fl antennae”) was erroneously missed in samples sent to Ken Christiansen for identification; its species is simply listed here as “unknown,” although it may or may not belong to a previously identified species.

Shain uses "a regular, old spoon" to scoop up thousands of worms into a cooler, then duct-tapes it shut and ships it back to Camden.
The threadlike, fl Mesenchytraeus solifugus -- which feed on microorganisms as they crawl through tiny ice cracks in coastal mountain glaciers in Alaska, British Columbia and Washington state -- thrive at around 0 degrees Fahrenheit, according to Shain.
Shain said NASA is interested because conditions on the glaciers are very much like the conditions on some cold planets that scientists theorize have a chance of harboring life.

Mountain climbers have observed ice worms (Oligochaeta: Plesiopora Enchytraeidae) of the species Mesenchytraeus solifugus rainierensis in snowfields of several Cascade mountains, especially Mount Rainier (R. Crawford, U. of Washington, 1998, oral comm.).
We collected one specimen from an ice wall in the largest of the St. Helens crater firn caves in August 1996, actively crawling approximately 1 cm beneath the ice surface.

The study included collection of an initial type collection along with pertinent biological and physical contextual data; identification and inventory of specimens; and limited analysis for preliminary statements of spatial and ecological distribution of identified taxa.
Dominant taxa included ice worms (Mesenchytraeus solifugus) and Collembola.
Newly species of Collembola were identified belonging to Isotoma (Myopia), Agrenia, and Isotoma (Desoria).
