Farmed ruminants are the largest source of anthropogenic methane emissions globally. The
methanogenic archaea responsible for these emissions use molecular hydrogen (H 2 ), …

Horizontal gene transfer (HGT) confers the rapid acquisition of novel traits and is pervasive
throughout microbial evolution. Despite the central role of HGT, the evolutionary forces that …

The majority of viruses within the gut are obligate bacterial viruses known as bacteriophages
(phages). Their bacteriotropism underscores the study of phage ecology in the gut, where …

Species loss within a microbial community can increase resource availability and spur
adaptive evolution. Environmental shifts that cause species loss or fluctuations in community …

Horizontal gene transfer (HGT) is important for microbial evolution, yet we know little about
the fitness effects and dynamics of horizontally transferred genetic variants. In this study, we …

Most viruses can infect multiple hosts, yet the selective mechanisms that maintain multi-host
generalists over single-host specialists remain an open question. Here we propagate …

Microbial communities are comprised of many species that coexist on small spatial scales.
This is difficult to explain because many interspecies interactions are competitive, and …

Sex is common among eukaryotes, but entails considerable costs. The selective conditions
that drive the evolutionary maintenance of sexual reproduction remain an open question. …

Not long ago, scientists paid dearly in time, money and skill for every nucleotide that they
sequenced. Today, DNA sequencing technologies epitomize the slogan ‘faster, easier, …

Horizontal gene transfer (HGT) is important for microbial evolution, but how evolutionary
forces shape the frequencies of horizontally transferred genetic variants in the absence of …
