Bryophyte pesticides. The liverwort, "Plagiochila," produces a chemical that is poisonous to mice. Other bryophytes produce chemicals that are antifeedants which protect them from being eaten by slugs. When "Phythium sphagnum" is sprinkled on the soil of germinating seeds, it inhibits growth of "damping off fungus" which would otherwise kill young seedlings. Commercial Peat is a fuel that is produced from dried bryophytes, typically "sphagnum." Bryophytes antibiotic properties and ability to retain water make them a useful packaging material for vegetables, flowers, and bulbs. Also, because of the antibiotic properties, "sphagnum" was used as a surgical dressing in World War I.
Moss teeth called peristome. This may be absent in some mosses. Most mosses rely on the wind to disperse the spores. In the genus "Sphagnum" the spores are projected about off the ground by compressed air contained in the capsules; the spores are accelerated to about 36,000 times the earth's gravitational acceleration "g". It has recently been found that microarthropods, such as springtails and mites, can effect moss fertilization and that this process is mediated by moss-emitted scents. Male and female fire moss, for example emit different and complex volatile organic scents. Female plants emit more compounds than male plants. Springtails
