Description:
Predicted Wood Thrush AHY Captures (per station-year)

I applied the second equivalent model (by ICOMP) to mapping predicted number of WOTH AHY captures. The model features affinities to deciduous forest in the 5km context (median >50%), and above ground biomass (median 94 MG/ha) which infers that captures increase from mid-successional deciduous forest through mature forest habitat).

The selected model suggests that conservation of Wood Thrush breeding habitat must preserve large tracts of mature deciduous forest. The productivity model differs.

Wood Thrush - VizBand/Land AIC Model Selection        Created: 31-May-2011

Wood Thrush annual capture rate of adult (ADULT) individuals (log transformed) ranged between -0.184 and +2.786 with a mean value of +1.301 and a median value of +1.299.

Model 1 (1 parameters)

Wood Thrush annual capture rate of adult (ADULT) individuals (log transformed) was a function of:

a) NLCD06DE5KP (+0.35682) - percent deciduous forest cover (LN + 1), 990m-resolution in a landscape context of 5km radius, ranged between +2.042 and +5.271 (95% CL) with a mean value of +3.657 and a median value of +3.962.

This model included data from 85 stations, explained 14 percent of the variation, and was statistically significant at a level of P<NaN.

Model 2 (2 parameters)

Wood Thrush annual capture rate of adult (ADULT) individuals (log transformed) was a function of:

a) AGBIO1K (+0.10030) - above ground biomass (Mg/ha; LN + 1), ranged between +0.889 and +6.840 (95% CL) with a mean value of +3.865 and a median value of +4.539,
b) NLCD06DE5KP (+0.24828) - percent deciduous forest cover (LN + 1), 990m-resolution in a landscape context of 5km radius, ranged between +2.042 and +5.271 (95% CL) with a mean value of +3.657 and a median value of +3.962.

This model included data from 85 stations, explained 16 percent of the variation, and was statistically significant at a level of P<0.00001.
