Summary
Many infectious diseases are spread via intermediary organisms, or “vectors”, such as mosquitoes or bats. These vectors can be attracted to, and feed on, multiple host species, each differing in their susceptibility to infection and their ability to transmit pathogens to others. Often, these host species are found in mixed-species assemblages, such as the choruses of frogs, where multiple species congregate around the same ponds to find mates. Understanding how the behavior of disease vectors in mixed-species assemblages influences disease transmission is essential to assess evolutionary respo
