“The snowpack is extremely low across much of the West, not because precipitation was extremely low … but specifically because temperatures were record warm. That is the classic signature of a warming climate on mountain snowpack,” @weatherwest.bsky.social told @edwardsanthonyb.bsky.social

🚨 Paper Alert!

In 2023, Mexican coral reefs experienced an unprecedented bleaching event.

But bleaching wasn’t the biggest issue.

Our study in Proceedings B @royalsociety.org shows a marine heatwave caused massive coral mortality and pushed reefs from production to net erosion

Calling all researchers working on *Genomics of Adaptation to Extreme Thermal Environments*
I'm serving as a guest editor of an upcoming collection in BMC Genomics and am eager to read your submission! More on scope and how to contribute here: bit.ly/4kH3PIx 🧪 @springer.springernature.com

‼️ ‼️ Paper alert ‼️ ‼️

Our latest study from the @oceanecol.bsky.social Lab in the @icrs.bsky.social journal @springernature.com shows why high-resolution temperature monitoring matters for assessing bleaching impacts.

🪸 A recent study by WHOI Reef Solutions scientists shows that microbes and genetic material in seawater change when nearby corals are sick. Seawater was a better indicator of disease than sampling the corals themselves.

@michaeltconnelly.bsky.social et al. sequenced 342 Pocillopora coral samples from the Eastern Tropical Pacific, revealing four distinct species; algal symbiont community profiling identified dominant symbionts that varied according to host species.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

NEW PAPER “Pioneer generation shapes long-term recovery of coral populations"

Here we challenge what a reef recovery looks like and show:

🪸 Early recruits drive long-term recovery
🪸Later recruits failed to survive
🪸 Apparent recovery masks declining diversity

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...
