Gut microbiota can evolve within their hosts on human-relevant timescales, but little is
known about how these changes influence (or are influenced by) the composition of their …

Multiple factors influence gut microbiome diversity in vertebrate hosts. Most previous studies
have only investigated specific factors and certain host species or taxa. However, a …

Over the past decade several studies have reported that the gut microbiomes of mammals
with similar dietary niches exhibit similar compositional and functional traits. However, these …

The microbiome shapes many host traits, yet the biology of microbiomes challenges
traditional evolutionary models. Here, we illustrate how integrating the microbiome into …

Different host species associate with distinct gut microbes in mammals, a pattern sometimes
referred to as phylosymbiosis. However, the processes shaping this host specificity are not …

Trophic networks are composed of many organisms hosting microbiota that interact with
their hosts and with each other. Yet, our knowledge of the factors driving variation in …

The mammalian gut microbiota is considered pivotal to host fitness, yet the determinants of
community composition remain poorly understood. Laboratory studies show that …

Comparative analyses of the control of mammalian microbiomes by host genetic architecture
reveal striking conserved features that have implications for the evolution of host …

Differences in the bacterial communities inhabiting mammalian gut microbiomes tend to
reflect the phylogenetic relatedness of their hosts, a pattern dubbed phylosymbiosis …

Gut bacteria can affect key aspects of host fitness, such as development, fecundity, and
lifespan, while the host, in turn, shapes the gut microbiome. However, it is unclear to what …
