For #phycologyfriday: The unusual fishhooks of Bonnemaisonia californica #rhodophyta #algae #seaweed #intertidal #marinelife #redalgae #marinebiology #science

Halosaccion glandiforme at Whiffin Spit. This red algae fills with water, likely to prevent desiccation. 🦑 #PhycologyFriday #Intertidal #tidepools

Today for #phycologyfriday: two commonly confused PNW kelps next to each other, from the same site (Whiffin Spit, BC). Left is Saccharina latissima, right Hedophyllum nigripes. #marinelife #intertidal #pnw #biology #marinebiology #science #kelp #seaweed

Pretty barnacles and sponges 🦑 #intertidal

For this #PhycologyFriday I'm happy to share my ✨new paper✨ about #kelp disease -> rdcu.be/ets28 Pink-spot disease occurs in kelp nurseries across North America and Europe according to our survey and we identified a bacteria (Algicola sp.) as the likely causative agent. 🦑 #aquaculture

Today for #phycologyfriday: Soranthera ulvoidea, a saccate brown alga that grows only on some species of red algae (in this case Odonthalia floccosa) #marinelife #tidepools #algae #seaweed

Lab grown stipeless bull kelp to reduce tangling in tumble culture. Removal of the stipe before the internal cavity inflates results in the cut sealing over to form a "knot" instead of the usual pneumatocyst + stipe #phycologyfriday #kelp #marinebiology #science #algae #seaweed

A gumboot chiton in a medley of seaweeds #phycologyfriday #intertidal #tidepool #marinelife

My ✨new paper✨ looking at how low salinity and high temperatures alter the bacterial community of sugar #kelp was just published! Lab and field results agree: the overall changes are small, but core taxa decrease under abiotic stress onlinelibrary.wiley.com/doi/10.1111/... #PhycologyFriday 🦑

Honoured to have been able to make speaker gifts for the 2025 international seaweed symposium! #phycologyfriday #iss25 #pottery #ceramics #kelp

A very unexpected find: Laminaria ephemera at Stanley Park in a seaweed diversity survey quadrat! I'll be presenting on this project (and others) at #ISS25 - see comments for details. #phycologyfriday

Drift Lessoniopsis for #PhycologyFriday. Lessoniopsis lives in very wave exposed areas. If you look closely at the stipes, you will find holes made by burrowing amphipods 🦑🧪🌊

Blink and you miss it: the spring bloom of Laminaria ephemera, one of the shortest-lived and smallest kelps #phycologyfriday #intertidal #marinelife #kelp #science

A rarity in Canadian waters: Laminaria sinclairii at French Beach, BC. #laminaria #phycologyfriday #kelp #seaweed #intertidal #marinelife #science #marinebiology #algae

For #PhycologyFriday, check out this gorgeous red algae (possibly Gloiocladia laciniata) that appears iridescent blue / purple underwater! Photo taken underwater ~6 m depth 🤿

Closeups of historical seaweed pressings from the University Herbarium in Berkeley for #PhycologyFriday

Today for #phycologyfriday: a couple of tiny bull kelp sprouting from the shell of a dogwinkle #bullkelp #nereocystis #kelp #phycology #seaweed #algae #marinelife #intertidal #marinebiology #science #tidepool

Happy #PhycologyFriday #Seaweed #Art

Today for #phycologyfriday: the gorgeous Erythrophyllum delesserioides, found along exposed, wave-swept coasts of the PNW #redalgae #erythrophyllum #phycology #marinelife #intertidal #marinebiology #seaweed #algae #science #botany

Antithamnionella spirographidis under a microscope. Collected at Stanley Park during a long term macroalgal survey by @siobhanschenk.bsky.social and I that was recently accepted as a paper cdnsciencepub.com/doi/abs/10.1... #phycologyfriday #marinelife #intertidal #seaweed #marineecology #science

Some Codium setchellii on a drift Pterygophora californica holdfast for #PhycologyFriday

From the edge of the Pacific in BC, Canada... I offer the compact but mighty 'Sea Palm', Postelsia palmaeformis, for this #PhycologyFriday. "I will bend but I will not break"

Curr. Biol. (2025) 10.1016/j.cub.2024.12.025  Kelp forests are integral + critical to aquatic ecosystems, but species such as giant kelp + bull kelp have experienced population bottlenecks in recent decades.

A purple sea urchin munching on some Hedophyllum sessile for #PhycologyFriday . This was on Calvert Island. #seaurchin #kelp 🦑

For #PhycologyFriday, here’s some Southern Sea Palm kelp (Eisenia arborea) and Giant Kelp (Macrocystis pyrifera sensu lato) from a swelly fun dive last December here in Huu-ay-aht territory, Barkley Sound, Vancouver Island

Today for #phycologyfriday: a rather unusual bull kelp that popped up in a lab tumble culture #bullkelp #nereocystis #kelp #seaweed #phycology #marinelife #intertidal #marinebiology #science #biology

A new in progress #pottery project for #phycologyfriday: #Alaria marginata carved on a bowl #kelp #seaweed #marineart #phycology #sculpture #carving #ceramics #clay

@varoon-supratya.bsky.social and I are celebrating #PhycologyFriday by continuing to collect data for our long-term monitoring project that is now accepted! cdnsciencepub.com/doi/abs/10.1... Read it for free on BioRXiv 🦑🧪 #botany #ecology #phycology

Some latest seaweed pressings from San Diego for #PhycologyFriday

Lab grown bull kelp sporophytes with tiny rhizoids and the barest hint of a stipe for #phycologyfriday #bullkelp #marinebiology #phycology #kelp #seaweed #algae #science #biology #marine #ocean

This disc coral rolls, slides, and pulses its dome-shaped body to “walk” in the direction of a light source. Learn more: https://scim.ag/40YcOvx

I may be biased, but elk kelp is *my* favorite canopy former The elusive elk #kelp (Pelgophycus porra) doesn't typically grow to the surface, instead these deep-dwelling giants can form extensive subsurface canopies from 20m down to 90m! How cool is that!? #PhycologyFriday #marinelife #phycyeah

Soranthera ulvoidea, an epiphytic brown alga, from Santa Rosa Island, Southern California for #PhycologyFriday.

My creative outlet is pottery, often inspired by seaweeds #phycologyfriday #phycology #kelp #marinebiology #science #art #pottery #sculpture #seaweed #ceramics

Meet the #fungi that live in the sea "Fungi don’t just live in soils and with land plants, or breaking down complex materials like wood. They also thrive in the marine environment" Cool article by @marinemicrobes.bsky.social ! theconversation.com/meet-the-fun...

First time I found a Laminaria ochroleuca with a curly stipe, I thought it unfortunate a whirlpool could do that 😅 Turns out there's a thing called twisted stipe disease #Phycology #PhycologyFriday

Did you know you can age some perennial kelps by counting rings just like trees? We aged populations of two species first surveyed in the '80s (by Klinger and DeWreede!) to see if their age structure had changed. Our new paper is out, just in time for #PhycologyFriday! doi.org/10.1111/jpy....

Not sure what encrusting coralline #algae this is, but I love the texture! Whenever I find encrusting corallines on animals I always wonder how the algae affects them. In this case, better camouflage vs extra weight are some things that come to mind. #PhycologyFriday #MarineLife #Phycology

A belated #PhycologyFriday post & small landmark for my job at Kelp Rescue Initiative: a gametophyte culture grown from spores of Bull #Kelp we restored with #greengravel last summer in K’omoks territory, which we seeded our first f/2 #restoration outplants with this week at VIU’s Deep Bay station!

Today for #phycologyfriday: intertidal bull kelp with extremely short stipes. Spotted at Ogden Point, Victoria BC #nereocystis #bullkelp #phycology #kelp #seaweed #algae #marinebiology #intertidal #science #victoriaBC #britishcolumbia #fieldwork

Check out my new pre-print about a novel #kelp disease! This research includes a kelp-grower survey (still live). 57% of respondents have seen pink-spot disease on their spools. One bacteria is associated with pink spots, a target for future research. www.biorxiv.org/content/10.1... #MarineLife

Does anyone else look back at tidepooling photos and think "how did I not see that"! In this case, I did not see the gumboot chiton. This was at Botanical Beach. #kelp #phycology #chiton #marinelife

Many similarities here, between the rapid decline of kelp ecosystems in Maine and southern Australia (and elsewhere). So many “canaries in the coal mine” around the world. www.nenc.news/2024-09-23/n...

Excited to announce our work on kelp genomics is now out at Current Biology. Lead by Postdoc extraordinaire Jordan Bemmels, we sequence WGS for 600+ bull and giant kelp across BC and Washington. authors.elsevier.com/a/1kSP93QW8S...

Hello🦋 Hoping for a nice platform to exchange science again. I'm a #kelp ecologist, finished my PhD last year on climate change impacts on kelp forests (🇬🇧 @thembauk.bsky.social, @dansmale1.bsky.social) & work now on microbes (🇨🇦 @ubcbotany.bsky.social, @hakaiinstitute.bsky.social).Happy kelpy times🌊🌱

Such a fun day! Too bad it doesn't press well

My favorite #kelp Postelsia palmaeformis for #PhycologyFriday! Being a tiny little thing that NEEDS to be battered by waves to survive is a crazy choice.

Today for #phycologyfriday: Dictyoneurum californicum at Sombrio Beach on Vancouver Island. This is a rare and patchily distributed species in Canada, being mostly found in California #dictyoneurum #phycology #marinebiology #seaweed #algae #botany #kelp #science #intertidal #ocean

NEW PUBLICATION assessed 217 global MPAs. MPAs with shared governance arrangements between governments and non-government actors are 98% more likely to have higher fish biomass than MPAs solely governed by state agencies. 🧪🌏🦑 #MPA #marinepolicy #fisheries journals.plos.org/plosone/arti...

For #PhycologyFriday, here are some Giant Kelp #greengravel from last month that I grew for my job with the Kelp Rescue Initiative! These got outplanted (after some more growth) here in traditional Huu-ay-aht territory right before the holidays for our #restoration experiments & efforts 🌊 #kelp
