Just the good news we need - a nature-based solution for climate change mitigation that could be scaled up to help with carbon sequestration plus is a tasty food source - at least for those of us that like oysters #ClimateChange #CO2reduction #OysterFarming
pnas.org Proceedings of the National Academy of Sciences @pnas.org · Sep 22
A delicious win-win: Oyster farming helps sequester carbon, not just because the bivalves lock CO2 in their shells but even more so because the oysters promote primary production and organic carbon sedimentation in the sea around them. In PNAS: www.pnas.org/doi/10.1073/...

As climate change will fundamentally change the environment

we cannot carry on with traditional conservation & hope that will be enough

We need to start investigating new approaches to maintain functioning ecosystems

I was always hoping there was a way to find the salmonid scientists on here easily. Now there is! Please comment to be added, it is (very) incomplete 🙏

I am still looking for a Master's student to join my lab at Northern Michigan University in fall 2025. Please get in touch if you are interested, and share with keen students interested in fish, genetics, or evolution!
Image of a poster with a photo of a lake beneath blue sky. Poster text: Graduate position in freshwater fish evolution. The Mandeville Lab at Northern Michigan University is recruiting a MS student to work on the evolutionary genomics of freshwater fish (fall 2025). Research in our lab group focuses on how evolutionary processes shape freshwater fish biodiversity. Specific focus areas include hybridization, effects of anthropogenic disturbance, population connectivity, and the evolution of fish sex determination mechanisms. Project topic will depend on the interests of the successful candidate. Ongoing work in the lab includes evolution of hybrid unisexual dace lineages, leuciscid minnow hybridization or demography in response to anthropogenic change, and genetic diversity or population connectivity of lake whitefish. Candidates interested in evolution, fish biology, ecology, genetics, conservation, or related fields are encouraged to apply. Desired qualifications include the ability to balance working independently and collaboratively, excellent work habits, and strong writing skills. Projects will involve analysis of high resolution genomic data, requiring computational approaches and high performance com- puting. No prior computational experience is required, but applicants must be enthusiastic about building their computational skills. The Mandeville Lab aims to promote equity, diversity, and inclusion, and encourages applications from students who are members of historically excluded or marginalized groups. NMU is located in Marquette, Michigan, in the Upper Peninsula of Michigan. Marquette is a small but vibrant city on the southern shore of Lake Superior, located close to beautiful natural areas. To apply, please send a letter of interest, CV, unofficial transcript, and contact information for 3 references to Dr. Liz Mandeville, lmandevi@nmu.edu. Review of applications will begin immediately and continue until a suitable candidate is identified.

There are 4 native lamprey species in the #GreatLakes (chestnut, silver, American brook + northern brook) and 1 invasive (sea lamprey). Chestnut lamprey is parasitic like the sea lamprey, but they cause less harm because of their much smaller size + co-evolution with native fish #25DaysofFishmas

Prepare for trouble and make it double, because #Fishmas Day 8 brings one fish with two identities!

Steelhead + Rainbow Trout are the same species - Oncorhynchus mykiss - with different lifestyles. While not native to the #GreatLakes, they're a favorite of anglers #SundayFishSketch #25DaysofFishmas
