Final Report - Center for Invasive Plant Management

Although this study was conduoted only over one growing season, it is the first study toexamine glomaiin concentrations (an AM hyphal product) over a grorving season in auinterrnountain grassland community. Every studv on glomalin in natural ecosvstellls thus thr hasnot considered the importance of seasonal fluctuations in glomalin (since only one time point5 was examined). Our study indicates that. i.vhile fluctr-rations in this seemingly stable soil pool arerelatively small, they were nevertheless significant itr our study. Hence a sampling regintecapturing seasonal variation may have to be employed in future studies measuring glomalin.Acknowledgmentsl0E.R.L. and N{.C.R. acknowledge funding fbr this project by the Center for lnvasive PlantManagement, located at Montana State University, the National Science Foundation, and thet-i.S.
