Since the #aDNA community is growing here, I’m sharing a new tutorial on ancient DNA, written by marine scientists with diverse backgrounds in #genomics. We share how to integrate best 'omics principles into aDNA research 🧬🧪🦑

Next up: code tutorials for aDNA packages, watch the MarineOmics space!

Today 14 scientific societies in #ecology #evolution and #marineScience are publishing the results of a survey that finds negative impacts of federal policies on food security, flood mitigation, infectious disease preparedness, and wildlife conservation: 🧪👩‍🔬 www.firsthandaccounts.org/impacts/2025...

This infographic describes the main results from a survey of members of 14 scientific societies. There is a pie chart showing that both academic (58%) and non-academic (42%) responded to the survey. It lists statistics: 85% of respondents reported uncertainty about the future; 71% reported federal training programs were "very" or "extremely important"; 83% reported negative impacts or irreparable harm on their field of science. There is a word cloud summarizing open-ended responses with the largest words "student research fund federal grant". Eight major themes in the responses are listed: disruption of research with societal important; concerns of closure of the USGS Bird Banding Lab; Early Career Bottleneck; Restricted Freedoms including travel and speech; Decline in Government Efficiency and Expertise; Concerns about Biased/Removed Data and Data Gaps; Concerns about the Ability to Meet Legal Mandates; and From Positive Impact to Irreparable Harm. There are icons for each participating society and a QR code for website and data availability.

Researchers found that 10.5% of shark and swordfish products from species listed as Near Threatened, Vulnerable, or Endangered (IUCN) in New England seafood markets were mislabeled.

New paper with @birdpicsandscience.bsky.social out TODAY!!

We found that choosing "highly informative loci" (aka high fst loci) may bias results in common population genetic analyses

‘Highly‐Informative’ Genetic Markers Can Bias Conclusions: Examples and General Solutions

High-grading bias is the overestimation power in a subset of loci caused by model overfitting. Using both empirical and simulated datasets, we show that high-grading bias can cause severe overestimat...

Congrats Anika!! 🦪

Come learn about some cool new coral disease research from my friend and (honorary) new lab mate Emily! #Evol2025 🪸 Will be a great talk.

Emily Trytten @emily-trytten.bsky.social · Jun 22

Super excited to be giving my first ever conference talk at #Evol2025 tomorrow! I’ll be sharing my work from my first chapter, which looks at disease associations for the coral epizootic white band disease. It’s in Pathogens and Disease at 2:30, hope to see you there!

Madeline Eppley @madeline-eppley.bsky.social · Jun 22

I’ll be chatting about oysters today at #Evol2025! 🦪 Drop by the Ecological Genetics III session in Olympia 2 at 3:00 pm to hear about some unexpected and exciting genetic results.

Yesterday I met with PA Senator Dave McCormick and the offices of Rep. Scott Perry and @fetterman.senate.gov to discuss the importance of federal funding for biological research with at least $9.9 billion for @NSF in FY2026. @aibsbiology.bsky.social #AIBSCVD2025

Happy to see our tools being used in a wide variety of conservation applications.

Starting the week off with some (much needed!) good news - my FIRST first-author manuscript has been published in #conservationgenetics 🌎✨🧪

Using DNA barcoding, I found that ~10% of swordfish sold in New England (USA) fish markets was actually shark, including the endangered shortfin mako 🦈

Thank you!!! Looking forward to the research highlight :)

thank you Samina!! 🫶🏻

thank you so much Kylea!! ☺️

Madeline Eppley @madeline-eppley.bsky.social · Feb 24

Thank you! It really is such a validating and exciting feeling to see the published version.

thank you Mya!!! 🫶

Thank you, Steve! I agree - I emphasized the value of a follow-up study in the manuscript now that import monitoring programs and fishing bans have had a few years to play out and impact market dynamics. I've pivoted for my PhD and am now doing eastern oyster pop gen ... but the door is wide open!

Thanks Randall!

Thank you!! 🦈

I am so happy to see this work from my undergrad finally reach publication. I graduated in 2020, although it took a few years given the hurdles of covid, starting a PhD, and getting through the qualifying exam process, I’m grateful to have seen this project through! #AcademicSky

Madeline Eppley @madeline-eppley.bsky.social · Feb 18

Samples were collected in 2019, just before the implementation a major import monitoring program and a shortfin mako fishing ban in the US. This work has established a temporal baseline that can be used to determine if market mislabeling has decreased from these initiatives! #fisheries #marinelife
