Sarah W. Davies Ph.D.

Exciting announcement! My new department is launching a postdoc fellowship in quantitative biology. Fellows will be co-advised by two Bio faculty, one that is quant focused (not me) and one that is not (me???). I would love to co-sponsor a postdoc and build a collaboration so please reach out!

Our latest piece, just out

We are thrilled to announce that, thanks to the support of our institutional subscribers, all Royal Society subscription journals will be open access in 2026 through #S2O. Researchers can read all articles and publish #OpenAccess in our eight subscription journals for free buff.ly/4Lu9VpW

I am seeking a postdoc to join my group at UCLA -- ideally the candidate would have some experience in either population genetics or microbes/microbiome (computational background needed). We have a range of projects and are happy to tailer to your interests. Please dm/email me if interested.

PhD position in population genetics of Caribbean corals at HIFMB. Ideal candidates have a master's in marine biology, and strong molecular skills. Apply by Feb 15, 2026. More info: https://www.baumslab.org/ #phd

She isolated a putative bacterial symbiont then cocultured it with axenic algal symbionts to ask how it impacted growth and gene expression - results were unexpected but do support a beneficial relationship - read more here rdcu.be/eUKQz

Boxing up the NSF at Eisenhower Av for the forced relocation. Boxes have “Details Matter” signage.

NSF

- Forced reorg

- POs down ~ 40% (DRP, most rotators not renewed, retirements)

- Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …)

I personally love the boxes they gave us for packing.
“Details matter” 🙃

Deep-sea corals near cold seeps associate with sulfur-oxidizing chemoautotrophs in the family Ca. Thioglobaceae - Microbiome Background Corals are known for their symbiotic relationships, yet there is limited evidence of chemoautotrophic associations. This is despite some corals occurring near cold seeps where chemosymbiotic fauna abound including mussels that host sulfur-oxidizing chemoautotrophs from the SUP05 cluster (family Ca. Thioglobaceae). We investigated whether corals near cold seeps associate with related bacteria and report here that these associations are widespread. Results We screened corals, water, and sediment for Thioglobaceae using 16S metabarcoding and found ASVs associated with corals at high relative abundance (10 – 91%). These ASVs were specific to coral hosts, absent in water samples, and rare or absent in sediment samples. Using metagenomics and transcriptomics, we assembled the genome of one phylotype associated with Paramuricea sp. B3 (ASV 4) which contained the genetic potential to oxidize sulfur and fix carbon, and confirmed that these pathways were transcriptionally active. Furthermore, its relative abundance was negatively correlated with the stable isotopic composition of its host coral’s tissue suggesting some contribution of chemoautotrophy to the coral holobiont. Conclusions We propose that some lineages of Thioglobaceae may facultatively supplement the diet of their host corals through chemoautotrophy at seeps or may provide essential amino acids or vitamins. This is the first documented association between chemoautotrophic symbionts and corals at seeps and suggests that the footprint of chemosynthetic environments is wider than currently understood.

Corals are masters of obtaining nutrition via symbioses, in the light and in the dark: deep sea corals can associate with sulfur-oxidizing chemoautotrophs, expressing pathways that oxidize sulfur and fix C. Corals hosting them derive some carbon from chemosynthesis. link.springer.com/article/10.1...

I’m recruiting a graduate student for Fall 2026. We are currently focused on functional genomics, using Cnidaria to study sensory system evolution and regeneration. But we also have other side projects about life history, sexual differentiation, and reproduction.

TWELVE open PhD positions - what a fantastic opportunity for aspiring ocean scientists! UAF is a fantastic university with really amazing faculty, and Fairbanks is a beautiful place for outdoorsy people.
