@levylacie.bsky.social a C:N:P paper for ya

After many years of work we present a preprint that doubles the numbers of Asgard genomes, revealing lots of new insights into their metabolism. Notably, lineages closely related to eukaryotes are capable of aerobic respiration!

@emilyraehyde.bsky.social We can now successfully retire. We've made it onto #jcampubs

After seeing this pointed out by @baym.lol, does anyone have any good alternatives to BioRender? Because this is not it 🧪

Bacterial ecology and evolution converge on seasonal and decadal scales Ecology and evolution are distinct theories, but the short lifespans and large population sizes of microbes allow evolution to unfold along contemporary ecological time scales. To document this in a natural system, we collected a two-decade, 471-metagenome time series from a single site in a freshwater lake, which we refer to as the TYMEFLIES dataset. This massive sampling and sequencing effort resulted in the reconstruction of 30,389 metagenomic-assembled genomes (MAGs) over 50% complete, which dereplicated into 2,855 distinct genomes (>96% nucleotide sequence identity). We found both ecological and evolutionary processes occurred at seasonal time scales. There were recurring annual patterns at the species level in abundances, nucleotide diversities (π), and single nucleotide variant (SNV) profiles for the majority of all taxa. During annual blooms, we observed both higher and lower nucleotide diversity, indicating that both ecological differentiation and competition drove evolutionary dynamics. Overlayed upon seasonal patterns, we observed long-term change in 20% of the species' SNV profiles including gradual changes, step changes, and disturbances followed by resilience. Most abrupt changes occurred in a single species, suggesting evolutionary drivers are highly specific. Nevertheless, seven members of the abundant Nanopelagicaceae family experienced abrupt change in 2012, an unusually hot and dry year. This shift coincided with increased numbers of genes under selection involved in amino acid and nucleic acid metabolism, suggesting fundamental organic nitrogen compounds drive strain differentiation in the most globally abundant freshwater family. Overall, we observed seasonal and decadal trends in both interspecific ecological and intraspecific evolutionary processes. The convergence of microbial ecology and evolution on the same time scales demonstrates that understanding microbiomes requires a new unified approach that views ecology and evolution as a single continuum. ### Competing Interest Statement The authors have declared no competing interest.

Been dreaming of this paper for a decade. 1 PhD and 1 postdoc later, here it is!

What do ecology and evolution look like in a 20-year microbiome time series? They blur together

Here's the AMAZING preprint from my lab mate @robinrohwer.bsky.social

Our latest preprint - Globally distributed marine Gemmatimonadota have unique genomic potentials

Hey folks - I'm a trained facilitator for the CIMER project, I run workshops on academic mentoring. I'm not allowed to take money for them, but you could pay travel for me. Hit me up if you're interested for your department. I could stop by on my midwest road trip this fall! #academicsky

Happy to share my 1st first first-author paper in preprint with co-first @luisvalentin.bsky.social! Here, we describe three complete Asgard Archaea genomes from wetland soil in a collaboration between the @archaeal.bsky.social lab and the Banfield Lab. #ArchaeaSky 1/

Hey all, I made a feed for Archaea related research on bsky, called #ArchaeaSky. Hope it is useful...

Day one (2nd trip) of sampling in the Florida Keys with @ianhewson.bsky.social. We are collection baseline data to assess how how the huge summer heatwave in Florida impacted microbes and ecosystem processes such a nutrient cycling @NIUSustain @NIUlive 🦠🧬🧫🌊
