Summary of species diversity, prevalence of Sin Nombre virus and density of deer mice (Peromyscus maniculatus) at 16 sites in central Utah sampled 2003–2005.

Site identifier includes geographic location (TJ = Tintic Junction; LS = Little Sahara; UL = Utah Lake) and the numeric code (3–19). Species diversity was estimated using Simpson's Index (D) for each site per season. Prevalence of SNV was estimated as the number of deer mice positive for SN viral antibodies divided by the total number of deer mice sampled at each site per season x 100%. Density of deer mice (no./ha) was estimated using program DISTANCE. Dashes indicate sites that were not sampled in a particular season.
