From: Landscape features and weather influence nest survival of a ground-nesting bird of conservation concern, the greater sage-grouse, in human-altered environments

Figure 4

Probability of daily nest survival of greater sage-grouse relative to independent variables. Relationships between the probability of daily nest survival (y-axis) for female greater sage-grouse in the Wind River Basin in central Wyoming, USA and independent variables (x-axis): (a) Julian date (first day of incubation), (b) percentage (in percent) of shrub cover at the nest site (15-m scale), (c) distance (in meters) to the nearest oil or gas well (distance variable was natural log-transformed), (d) distance (in meters) to mesic habitat (distance variable was natural log-transformed), and (e) maximum wind speed (in kilometers per hour; data was fit using a quadratic term for wind speed). Maximum wind speed was recorded on the day of nest failure. The x-axis is scaled to the range of observed values. Numbers next to arrows on each figure represent the probability of nest survival at minimum and maximum values when extrapolated across the entire nesting season (i.e., twenty-seven 1-day intervals).
