Friday SCOOP: @vox.com has learned that USFWS has frozen its vast portfolio of international conservation grants. This is far beyond the scope of USAID-funded work and will inevitably harm wildlife internationally and in the US. @benjij.bsky.social has the story: www.vox.com/down-to-eart...

The firings and upheaval (including protest resignations by principled, eithical program directors)at our premier US Science Funding Agency, #NSF, directly undermine US science capability and is a direct attack on Academic Institutions. Kudos @jonlambert.bsky.social

Grazing by small #herbivores associated with a 29% increase in eelgrass #disease, contributing to huge losses in meadow areas from San Diego to Alaska.Nice story from @cornellcals.bsky.social summarizing our #eelgrass double-header in Ecology; Dr Graham cover photo! news.cornell.edu/stories/2025...

Great low tide at #HopkinsMarineStation shared with our Waves of Convergence #Stanford workshop. #Nudibranchs (Hermissenda and Doriopsilla), and Long-arm #brittlestar

#Herbivores facilitate disease spread in #eelgrass. So proud of Team Eelgrass lead by Dr Olivia J Graham. And cool cover photo! esajournals.onlinelibrary.wiley.com/doi/full/10.... #marinelife #seagrass #herbivores #vector #isopods #invertebrates #diseaseecology #disease

Galleys for The Ocean’s Menagerie! The #OceansMenagerie, about #SpinelessSuperpowers, releases Earthday 2025. #sponges, #corals, #nudibranchs, #seastars, #giantclams and #octopus! Andrea Dingeldein diagrams for coral chapters. #marinelife #invertebrates #tidepools #diving #scicom #artandscience

Seeing Red under Rocks on my #spineless meanders: #batstar rainbows, dwarf red sea cucumber (Lissothuria nutriens), red #sponge with purple sea urchins and Ophlitaspongia red sponge with red Rostanga pulchra #nudibranch and red egg mass (colored w sponge pigment) #marinelife #intertidal #invert

One of my big heros: Julie Packard, who created the fabulous Monterey Bay Aquarium @montereyaq.bsky.social‬. Thank you Julie! She Made Things Better Down Where It’s Wetter www.nytimes.com/2025/01/15/s...

Low-tide at #GreatTidePool. #Ricketts and #Steinbeck were right about the richness of #invertebrates here! Lots today starting with a flat crab, a two-spot #octopus, brooding anemone and 4 #nudibranchs. #marinelife #invertebrate #GreatTidePool #octopus #Tidepool

A day for chitons on low tides near Ed Rickett’s Great Tide Pool in Pacific Grove. Here's a huge gumboot chiton chillin' with a bat star and lined and mossy chitons below. #marinelife #intertidal #chiton #invertebrates

A few of my favorite tidepool shots of 2024 from San Juan Island and Monterey, better late than never for #invertefest! #marinelife #tidepool #invert #nudibranch #seastar

My #Invertefest holiday attempt at Hopkins Rose watercolor. Like a flamingo, it uptakes color from its prey, a red/pink bryozoan. It was named by Frank Macfarland in 1905 after Timothy Hopkins, patron of Hopkins Marine Lab. #invertefest #marinelife #nudibranch #invert #GreatTidepool #Tidepool

The sky has been growing 10 per cent brighter each year, undermining conservation of some wildlife, making areas with star parks like Huu-ay-aht, near Bamfield, BC increasingly rare. thenarwhal.ca/bc-bamfield-...

For Invertefest day 1 and celebrating King Tides is my 5 Phylum intertidal cave. How many different Invert groups can you find from this Monterey tidepool cave? #Invertefest #marinelife #invert #tidepool

SeaGrass is good for algal farming. IceIce disease is lower on algal farms with seagrass in Indonesia. Congrats to our team JoleahLamb, EvanFiorenza, NurAbu, JamaluddinJompa pnas.org/doi/10.1073/... #ecosystemservices #plantdisease #oceanfarming #aquaculture #bluefoods #plantmicrobeinteractions

Full moon rising over Monterey Bay and the Stars are out on a King Tide. Such a brilliant diversity! Bat stars, ochre stars, baby blood stars, and brittle stars! #Marinelife #Invert #lowtide #tidepool #intertidal #seastar

Brittle star (maybe Ophiothrix sp) in tidepools on king-tide near batstar nursery on my spineless meanders. Those tubefeet! #marinelife #inverts #kingtide #intertidal #beach

Baby batstar nursery and brittlestar on kingtide near Ed Rickett's Giant Tidepool. Love all these happy batstars chillin' in big waves here. #tidepool #marinelife #invertebrates #seastar #inverts #ocean #beach #kingtide

So proud of Dr. Olivia Graham's NEW paper showing herbivores can facilitate eelgrass wasting disease by creating wounds in eelgrass. Disease prevalence was 29 ± 4.7% higher on eelgrass leaves with herbivore scars than without. Isopods and snails! esajournals.onlinelibrary.wiley.com/doi/full/10....

Beautiful paper about the global danger of ship strikes for large #whales and the value of slowing down shipping. @seattletimes-rss.bsky.social focussed on more local #SalishSea dangers for whales and shipping. kudos anna nisi, @trevorabranch.bsky.social, team. www.science.org/doi/10.1126/...

Spineless meanderings was scarey in big surf at Pt Lobos #tidepools. The next #wave was bigger and I ran away. The clown #nudibranchs were out and a Hemigrapsus nudis crab was hiding with a baby ochre star and Haliclona sponge. Celebrating 1,000 followers and great Bluesky content! #marinelife

Mass bleaching of corals on the Great Barrier Reef in early 2024 was the most severe and most widespread yet recorded - surpassing 1998, 2002, 2016, 2017, 2020 & 2022. The overall mortality rate this year will exceed the 30% loss in 2016. www.nature.com/articles/s41...

Last month was the 2nd warmest October on record for the average global sea surface temperature... 🌊 Graphic using NOAA ERSSTv5 data (psl.noaa.gov/data/gridded...). Methods detailed in doi.org/10.1175/JCLI....

How about 180 year old #Blaschka masterpieces? These four are for #nudivember, crafted by the Blaschka's circa 1870. And a reminder that my book, A Sea of Glass, is a diving quest for the living matches; a lovely gift for those who love glass, #marinelife and #invertebrates. tinyurl.com/394pp5ty
