Their effect on nutrient cycles was examined.     Since the flux of nitrogen through termite colonies is greater than the amount present as termite biomass, this element &quot;turns over&quot; about 3 1/2 times annually in termite colonies.  The perennial shrub nitrogen &quot;turns over&quot; in 9.4 years, the litter in 2.8 years, and the annual forbs and grass component in 1 year.     Phosphorus &quot;turns over&quot; 2.5 times annually in termite colonies, in 12.6 years in perennial shrubs, 5.8 years in dead plant litter and in 1 year in annual forbs and grasses.     Sulfur &quot;turns over&quot; 2.5 times annually in termite colonies, in 13.0 years in perennial shrubs, 2.4 years in dead plant litter and in 1 year in annual forbs and grasses.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.1980-92156</style></accession-num></record></records></xml>
