Summary

Nevada’s large open spaces and diversity of habitat types supports a wide variety of wildlife species as well as domestic livestock. These conditions lend themselves to the uniqueness of the state but also provide habitat for many tick species. Important tick borne diseases have been diagnosed in humans and domestic animals within Nevada but little is known about the distribution and composition of tick populations throughout the state. Most of my efforts go into investigating the role of tick borne disease in the health of cattle herds throughout Nevada. Currently I am identifing important tick species, and the diseases they carry.

Host plant-mediation of viral transmission and its consequences for a native butterfly
The use of a novel host plant may confer fitness benefits in terms of survival and reduced viral transmission when larvae feeding on it are infected with this pathogen, supporting hypotheses of potential evolutionary advantages of a host range expansion in the context of tritrophic interactions.
