abstract
Diversity, abundance, and biomass of small-mammal populations increased 1 yr-post-spray on glyphosate-treated sites. These changes were ephemeral and the above parameters were similar to pre-spray values 2 yr after application. Changes were primarily a result of the increase in numbers of Microtus oregoni following an increase in grass and forb cover on treated grids 1 yr post-spray.-from Authors
