Hurdle model analysis of Ixodes scapularis infestation rates on Peromyscus leucopus with land-use, ecotone, and distance up river included as fixed effects and year and month included as random effects

Zero-inflation model (infestation frequency)
	Estimate	Std. Error	Z	P
Land-use—Recreational	0.775	0.215	3.600	<0.001*
Land-use—Ag/Industrial	0.662	0.182	3.643	<0.001*
Ecotone—Forest	0.155	0.154	1.010	0.312
Distance Up River	0.245	0.049	4.978	<0.001*

Conditional model (infestation intensity)
	Estimate	Std. Error	Z	P
Land-use—Recreational	0.002	0.086	0.024	0.981
Land-use—Ag/Industrial	0.119	0.104	1.599	0.110
Ecotone—Forest	−0.229	0.065	−3.527	<0.001*
Distance Up River	−0.008	0.020	−0.405	0.686

“Residential” is the reference level for the land-use category and “Edge” is the reference level for the ecotone category.
