manuscript. We thank Marci Baiz, Lisa Bol, Heather 
Danhof. Angel Hayden. Liberty Hightower, and Matthew 
Romcyn for assistance in the field and laboratory. Hahn and 
i fflbardo conceived the project. Stantbaugh, Houdek. and 
ymbardn collected samples in the field. Stambaugh. 
Houdek. and Thorpe conducted microbiocidal assays. All 
ointributed to writing the manuscript. Funding was 
iiivided by the McNair Scholars Program and NSF/S- 
STB1S Program to the senior author, a GVSU Summer 
Student Scholars Program award to B. J. Houdek. and the 
GVSU Department of Biology. The GVSU 1ACUC 
approved this study. Use of trade, product, or firm names
