Our most recent paper is out @NatureEcoEvo! We characterized the temporal dynamics of viral, bacterial, and relic DNA via a highly replicated microcosm setup: 4 grassland soils, 7 time points, 144 viromes, 84 metagenomes, and 84 16S rRNA gene profiles.

First step in a community project to provide a uniformly assembled, annotated and searchable set of bacterial genomes, our preprint on our initial release of 1.9 million genome assemblies+taxonomic estimates. (figure compares with previous 661k dataset)

We updated our paper: Systematic Discovery of Antibacterial and Antifungal Bacterial Toxins

@sudu59 Thanks! This link should work https://t.co/e9Uu0Xr4ir

This is *why* methods matter for #SoilHealth indicators: the 24 hr interval of the #HaneyTest represents an entirely different microbial community activity than at 72 or 96 hrs (as in the Cornell test).

@ChenxinLi2 Thanks, Li!

Soil viruses the minute the first seasonal rainfall hits the ground:

Despite vast compositional differences across soils, rewetting of dry soils consistently resulted in a bloom of viral diversity (up to a >30-fold increase in vOTU richness 24 h after wet-up!), followed by extreme turnover of viral populations.

Thanks to @jemersonmicro and the rest of the team for all their support. Thanks also to @j_kosmopoulos and @KarthikGeomicro for this wonderful commentary: https://t.co/9CGzYrtVki

Rewetting also rapidly depleted relic DNA, which subsequently reaccumulated, indicating substantial new microbial mortality in the days after wet-up

@dirt_toucher @Jeffinerca These two might be of interest

New paper alert!🌋🌊🧬🦠 I'm so excited to share our paper "Viruses interact with hosts that span distantly related microbial domains in dense hydrothermal mats" 1/ https://t.co/HtPUWbFvbL

[Clément Coclet @ClementCoclet]

🚨Preprint alert!

Excited to share our newest #preprint on #virus diversity and activity in high-altitude soils.

A joint effort with @simroux_virus and @elbrodie’ Group 🙏.

Check it out here: https://t.co/gJN3UJS7XQ

[Christian Santos-Medellín @cmsantosm]

@acritschristoph https://t.co/WUae13L7ez maybe this one?

[Christian Santos-Medellín @cmsantosm]

Happy to share a new preprint with @jemersonmicro. Viral communities with minimal compositional overlap display remarkably similar successional trends upon rewetting dry soils.

This is a great opportunity for any microbial ecologist looking for a postdoc. Exciting research topic, phenomenal advisor, and great colleagues.

[Joanne Emerson @jemersonmicro]

Our lab at UC Davis is looking for a soil viral ecology postdoc, but we can't formally advertise it yet, due to [recent successful negotiations that will absolutely be accounted for]. Avail. now, open to waiting for right candidate. More hopefully soon!

[DOE Office of Science @doescience]

Viruses are tiny, but play a big ecological role. Researchers @ucdavis, @ucmerced, @UCBerkeley & @Livermore_Lab monitored areas of grasslands, with some only getting 50% of average rainfall. They found the viruses reacted quickly to the drought conditions: https://t.co/9MlRj861Av
