Estimates of winter body fat on treated and un-treated study areas.

<p>Scaled estimates of late winter percent ingest free body fat (%IFBF), with 95% prediction intervals, for adult female mule deer in southwest Colorado. Solid gray bars reflect estimates for our treatment study area (Billy Creek State Wildlife Area) and white bars reflect estimates for our reference study area (Buckhorn Mountain). Estimates and prediction intervals were generated according to the model in which chest girth was held constant at the observed mean of 95.476 cm and coefficient estimates have been model averaged based on model results.</p

Akaike's Information Criterion cumulative model weights (), multiple linear regression coefficients , and standard errors for body condition predictor variables for adult female mule deer.

<p>Data were collected in southwest Colorado during early March, 2007–2009. A balanced model set was used such that all response variables appeared in an equal number of models, thus cumulative model weights >0.5 are attributed to variables that are most important.</p><p>Akaike's Information Criterion cumulative model weights (), multiple linear regression coefficients , and standard errors for body condition predictor variables for adult female mule deer.</p

Location of 2 study areas in southwest Colorado.

<p>The Buckhorn study area was located in Montrose county, designated by hash marks from lower left to upper right. The Billy Creek study area was located in Ouray county, designated by hash marks from lower right to upper left. Habitat treatments are depicted by red polygons inside the Billy Creek study area boundaries.</p

Probability of pregnancy for different age classes of adult female mule deer, with 95% confidence intervals, for adult mule deer in southwest Colorado.

<p>No discernible difference in probability of pregnancy between our treatment and reference study areas was observed, although evidence for senescence in older age classes was observed.</p
