A) Average crude protein (%, ± SE) and B) artemiseole (µg/g dry weight, ± SE) between browsed (closed circles) and unbrowsed plants (open circle) on burrows that have been occupied by pygmy rabbits for short (1–2 years) and long (6–7 years) amounts of time in October 2009 at the Leadore site in Idaho. Crude protein (%) for short occupancy, browsed: 13.22 ± 0.41; short occupancy, unbrowsed: 12.71 ± 0.29; long occupancy, browsed: 13.66 ± 0.33; long occupancy, unbrowsed: 12.32 ± 0.31. Artemiseole (µg/g dry weight) for short occupancy, browsed: 5444.77 ± 550; short occupancy, unbrowsed: 6502.81 ± 537; long occupancy, browsed: 544 6441.15 ± 481; long occupancy, unbrowsed: 7796.31 ± 658.
