In our project AGAPA (“Adaptaciones Genómicas a la Aridificación en Procariotas Acuáticos"), we aim to study microbial genomic adaptations to drought episodes in the “Las Tablas de Daimiel” National Park (Spain) via metagenomics.

I am really happy to share that I have been awarded by the Spanish national network “Conexión Microbioma” to support a new collaboration between our lab (@gecko1990.bsky.social) with @josepramoneda.bsky.social at the CEAB-CSIC (@ceabcsic.bsky.social).

Another great collaboration is out! ⭐️

Metabolic interplay drives population cycles in a cross-feeding microbial community - Nature Communications Here the authors leverage a crossfeeding, engineered microbial community to demonstrate that strain abundance cycles are robust across environmental conditions. They pair this with a nonlinear dynamic model to elucidate population cycles.

I'd like to thank all the great researchers involved in this MS (A. Pacheco-Valenciana, L. M. Rodriguez-R., F. Milke, @jennahed.bsky.social, @mesohaline.bsky.social, @microjustyna.bsky.social and G. Wienhausen), and particularly @sarilog.bsky.social for her huge support throughout my PhD studies 🩵

Here, we explore the relationship between genome streamlining and the prevalence and abundance of freshwater prokaryotes. We also investigate their co-occurrence across global freshwater metagenome, and its potential link to metabolic interdependencies and streamlining. 🧬🦠

Does genome streamlining influence the prevalence and abundance of freshwater prokaryotes?
Does metabolic interdependencies influence the co-occurrence of prokaryotes in freshwater ecosytems?
