Models of Monitoring Avian Productivity and Survival (MAPS) demographic data and high-resolution land cover data The top selected model of productivity indices suggested that productivity indices increased with distance from streams, where local coniferous forest cover (2km context) increased from 10 and 25% (mean `17%), within total forest cover of ~20% in a 2km context (N = 84, R2 = 0.26, P<0.0001). MacGillivray's Warbler station lifetime productivity (STAPI) (log transformed) ranged between +0.090 and +0.564 with a mean value of +0.327 and a median value of +0.325. ________________________________________ Model 1 (3 parameters) MacGillivray's Warbler station lifetime productivity (STAPI) (log transformed)...
Breeding Bird Survey Relative Abundance for MacGillivray's Warbler
The selected landscape model (equivalent by ICOMP) for MacGillivray’s Warbler adult captures (Table 1) suggests that adults were increasingly more commonly captured in low- to mid-elevation (median ~1,100m) landscapes with extensive coniferous forest (40-100%) in the 5km context, and a mean shrubland cover of 8% (N = 84, R2 = 0.21, P<0.0005) locally (990m). This model was masked to remove zero or negative values and clipped to display in cells for which the 5km coniferous context was in excess of 40% (L95CL) MacGillivray's Warbler - VizBand/Land AIC Model Selection Created: 17-May-2011 Exp(("nlcd06co5p" * 0.01344) + ("gtopo30_ln" * 0.04323) + ("nlcd06sh33ln" * 0.18160)) - 1 MacGillivray's Warbler annual capture...
