Farrell et al. @bigelowlab.bsky.social on shifts from #kelp to algal turf: "It is very analogous from a terrestrial forest going to a grassland. To see that, just in the span of a few years with your very eyes, is something pretty profound." 🌊🦑🧪 esajournals.onlinelibrary.wiley.com/doi/full/10....

From kelp forests to turf reefs: Patterns, drivers, and impacts to functional diversity

Kelp forests are declining in many regions due to ocean warming, predator loss, and other anthropogenic stressors. In areas of rapid ocean warming, including the southern Gulf of Maine, these ecosyst...

Solid work highlighting climate-change risk to a “tough” species touted for its ability to resist environmental variability & buffer other species against environmental stress: “even the hardiest species may struggle to keep up with the pace of warming.” #MarineLife #Seaweed 🌍🌊🦑

Climate change threatens even the tough ones. Our new study shows that even Ascophyllum nodosum, a tough brown seaweed, struggles with rapid temperature swings during low tides, and populations across Europe vary in their heat tolerance. Read more here: jecologyblog.com/2025/05/20/c...

Well this is worrying.

Great evening, gathering the COASTFRAG group at the #ITRS2025 conference in Brest, France, for discussions of results and plans for our intertidal rockweeds habitat fragmentation work.

Part of our team is attending the 14th International Temperate Reef Symposium (ITRS) in Brest!

Really interesting talk Gray William about gastropods and nerdy rocky shore science at #ITRS205. We can learn a lot from intertidal snails. 🧪🦑

More from @twernberg.bsky.social at #ITRS2025: We must to step up seriously if we want to stop and repair kelp loss. Is it even feasible? Daunting amount of restoration projects needed (maybe millions).

At #ITRS2025: @twernberg.bsky.social talks about the Phycocene, and that we need to have honest discussions about solutions for saving our oceans and #kelp forests. 🧪🦑
