Data was acquired during aerial surveys conducted by Montana Fish, Wildlife & Parks (FWP) between 1991 and 2003. The aerial surveys were conducted annually to count and classify mule deer in the area. Data are used by Montana Fish, Wildlife & Parks in their management responsibilities to set hunting seasons, determine population trends, and identify critical habitats. Observations were recorded on data forms and locations either plotted on USFS Maps (Deerlodge National Forest) or recorded by specific location. The data represents winter observations of mule deer. It is not intended to represent overall or annual distribution. Each individual observation represents one or more animals. Density of observations...

The shortgrass steppe is a semi-arid grassland, where elevated CO2 reduces stomatal conductance and promotes soil moisture storage. Enhanced biomass growth from elevated CO2 has been attributed in part to soil moisture effects. However, the influence of this soil moisture feedback on C cycling has received little attention. We used open-top chambers to increase atmospheric CO2 concentrations to twice-ambient for four growing seasons. Soil respiration rates and stable C isotopes of soil CO2 were measured during the third and fourth seasons. Elevated CO2 increased soil respiration rates by ?25% in a moist growing season and by ?85% in a dry season. Stable C isotope partitioning of soil respiration into its components...
