Overall, we found that these forams are pretty robust against coastal acidification, but there is a real risk of pushing conditions too far and increasing their susceptibility to dissolution!

This likely results from the chamber formation mechanism, which involves maintaining internal pH by exporting protons. This acidifies the environment near the newest chamber. When the environment is already high-pCO2, the foram experiences a "tipping point" into under-saturation and dissolution!

We found some exciting trends. In short, the most dramatic impacts of acidification were between live and dead tests, indicating that they are compensating for the acidification.

Even more interestingly, there are variations in the response by chamber (see attached chamber-by-chamber effect size)

in this work, we looked at the chamber-by-chamber responses of a salt marsh foraminifera, to varying levels of coastal acidification, all the way down to pH 7.2!

Excited to announce that Chapter 2 from my thesis, wherein i accidentally take a very fun detour away from 'omics, is live!

Quantifying the Temporal Dynamics of Marine Biodiversity Under Anthropogenic Impacts Using eDNA Metabarcoding This study uses eDNA to explore marine biodiversity changes under anthropogenic impacts, with a focus on marine community dynamics. Through the use of eDNA metabarcoding, the research identified 814 ....

Our new study shows how eDNA can track fine scale marine biodiversity loss under human impacts. Using a large scale mesocosm experiment we monitored temporal dynamics in bio-accumulation, response to stressors and eDNA degradation #eDNA #MarineBiodiversity onlinelibrary.wiley.com/doi/full/10....

You get a doctorate in Biology and it makes you think you're quite good at it.

Then your partner starts studying for the praxis and you're reminded plants exist...

Cool preprint showing the application of multimodal machine learning to #eDNA research and how explicitly incorporating other types of data can improve your results

I am working on a multimodal machine learning approach for eDNA too (stay tuned 😉) and it's great to see this method getting traction!

Explainable Multimodal Machine Learning Using Combined Environmental DNA and Biogeographic Features for Ecosystem Biomonitoring Machine learning (ML) has been proposed as a taxonomy-independent approach using environmental DNA (eDNA) for ecosystem biomonitoring. Representations of eDNA amplicons either as clustered sequences t...

Nice reporting from @meganewald.bsky.social on point if use #eDNA detections of West African Manatees

Excited for what the future holds in being able to rapidly test for endangered cryptic species - particularly the rotund ones

Remember in math class when your teacher always said you have to show your work?

Yeah I’ve been think about that a lot this week.

If you don’t share the data, you
don’t share the math, and don’t provide the sources, then we do not trust you.

Hi! 👋 New her from Twitter and also transitioning from studying #foraminifera at URI to doing #fisheries #edna work at NOAA!

Me! I'm moving from studying protists to fish and now need to network from scratch 😭
