Impact of Solenopsis invicta on small mammal habitat utilization and abundance
Vita. Habitat use by small mammals at a prairie site in central Texas was examined on a 1.44 ha grid from which red imported fire ants (Solenopsis invictal were removed, and on an adjacent control grid containing natural densities of fire ants during a 22-month markrecapture study (February 1991-Nov...
