Winter is coming—The role of seasonality through the lens of the rodent virome

Abstract

Rodent virus communities (viromes) are overrepresented with zoonotic viruses, and as such are a key host system for the study of zoonotic viruses. However, the extent of viral diversity beyond characterized zoonotic viruses, and the factors that modulate the viromes of rodents remain opaque. In this issue of Molecular Ecology, Raghwani et al. (2023) use rodents as a model to understand the role of seasonality in dictating virome abundance and composition—a factor known to play an important role in most animal one‐host, one‐pathogen systems. These data are not only highly relevant to rodents, but have broad applications across understanding and disentangling animal virome ecology.
