The human gut is inhabited by trillions of microorganisms composing a dynamic ecosystem
implicated in health and disease. The composition of the gut microbiota is unique to each …

Temperature is a prominent abiotic environmental variable that drives the adaptive
trajectories of animal lineages and structures the composition of animal communities. Global …

Humans, like all mammals, depend on the gut microbiome for digestion of cellulose, the
main component of plant fiber. However, evidence for cellulose fermentation in the human …

Host-associated microbiomes play an increasingly appreciated role in animal metabolism,
immunity and health. The microbes in turn depend on their host for resources and can be …

Background Eubacterium rectale is one of the most prevalent human gut bacteria, but its
diversity and population genetics are not well understood because large-scale whole …

Seasonal variations in gut microbiota of small mammals and how they are influenced by
environmental variables are relatively poorly understood. We sampled 162 wild plateau …

Background An individual's microbiome changes over the course of its lifetime, especially
during infancy, and again in old age. Confounding factors such as diet and healthcare make …

Studies in multiple host species have shown that gut microbial diversity and composition
change during pregnancy and lactation. However, the specific mechanisms underlying …

Human gut microbial dynamics are highly individualized, making it challenging to link
microbiota to health and to design universal microbiome therapies. This individuality is …

The gut microbiota is critical for host function. Among mammals, host phylogenetic
relatedness and diet are strong drivers of gut microbiota structure, but one factor may be …
