Table 4. Parameter estimates and standard errors (SE) for the environmental covariates featured in the top-ranking models describing the resource selection of deer that were seronegative and seropositive for Jamestown Canyon virus, Cook County, Illinois (1996–1999).

Significant parameters (α = 0.05) are in bold type face.

Parameter estimate (SE)
	POP	RIVER	ROAD	STAG	PRECIP t	STAG * PRECIP t	ROAD * PRECIP t
Seronegative	---	---	---	0.09 (0.06)	-0.32 (0.18)	-0.17 (0.06)	---
Seropositive	-0.73 (0.10)	0.40 (0.07)	0.27 (0.07)	---	0.11 (0.21)	---	0.12 (0.06)

POP is distance to nearest populated place, RIVER is distance to nearest river, ROAD is length of road in each grid cell, STAG is proportion of wetlands in each grid cell, PRECIP t is total precipitation level in year t.
