With a Little Help from My Friends: Microbial Partners in Integrative and Comparative Biology—An Introduction to the Symposium

Synopsis

The role that host-associated microbes play in animal biology is gaining attention in comparative biology. Numerous research groups study the roles that microbes play in human health and nutrition, or in enhancing the production of agricultural animals. However, inclusion of host-associated microbes into research questions of integrative and comparative biology has lagged behind. We hosted a symposium to bring together top researchers in the field of host-associated microbes who also incorporate aspects of integrative and comparative biology. In this introduction, we highlight recent research demonstrating the profound roles that host-associated microbes play in many aspects of animal biology, such as immune function, endocrinology, and even behavior. It is our hope that integrative and comparative biologists will begin to include aspects of host-associated microbes into their research programs, enhancing both the fields of comparative biology and host–microbe interactions.
