Metrics of mammal activity used in the analysis.

Metric of mammal activity	Formulation of metrics	Biological relevance
Cotton rat activity	Number of unique cotton rats captured per site	Cotton rat is the only laboratory-confirmed vertebrate host of EVEV.
Non-rodent diversity	Shannon index of non-rodent activity	Greater diversity of non-rodents may reduce rodent blood meals and EVEV prevalence.
Non-rodent activity	Average non-rodent activity (number of independent pictures of each species/number of days cameras were active)	Higher activity of non-rodents may reduce rodent blood meals and EVEV prevalence.
Relative cotton rat host use	Ratio of blood meals from cotton rats to all other animals.	Cotton rats are the only confirmed natural host for which all host competence criteria are satisfied.
