Trying to grow nori in Northern BC PhD in Botany

My involvement was only possible due to my PhD supervisor's (Laura W. Parfrey) support by including me in this endeavor. I also want to highlight the additional work Emily G. Aguirre put in to keep us all on track and coordinate with the publisher.

I'm excited to share that for this #phycologyfriday there is a new algae textbook: Advances in Temperate Phyconomy: Algal Harvest and Cultivation in Globally Distributed Temperate Waters link.springer.com/book/10.1007... I helped write chapter 24, which talks about biobanking algae and microbes

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
Two large bladed kelps lying next to one another on an eelgrass bed. The left kelp is Saccharina latissima, with a narrower and lighter colored blade and stipe, while the right kelp is Hedophyllum nigripes, with a broad dark blade A close up of the stipes of two large kelps. Saccharina on the top has a narrow rounded stipe, Hedophyllum nigripes on the bottom has a broad flattened stipe

A more accurate sentence would be: "UBC botanists describe "pink-spot disease" in kelp nurseries." Please fix this on Twitter as well. You can contact the corresponding author and/or UBC researcher listed on the manuscript by email before posting to avoid this in the future.
Cultivation of kelp and other macroalgae is a growing industry in North America. In the well established macroalgal growing regions in Asia and Africa, macroalgal disease cause crop losses, placing a significant economic burden on growers. As kelp cultivation intensifies in North America, disease prevalence is expected to increase in tandem. Here, we describe the prevalence and bacterial community associated with a novel disease of kelp in the land based nursery stage that is characterized by bright pink spots, termed pink-spot disease. With input from the kelp-growing community through an online survey, we show that pink-spot disease has been widely observed in Canada and the United States on nursery cultivation spools of the kelps Saccharina latissima, Alaria marginata, Nereocystis luetkeana, and Macrocystis

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

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

I will forever be haunted by this footage. Trawling has only been filmed underwater a few times in documentary history, and never with such clarity. What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives. 🌎🦑🧪

For #PhycologyFriday this week let's celebrate #ISS25 and #tidepools. Although tidepools are a harsh environment, I love them because the still water makes it easier to see critters and algae 🦑

Eastern US let's fucking goooooo We've got hundreds of millions of precious migrants pouring overhead tonight and in the next few weeks. Get those overnight lights off, cats inside, and windows treated (to prevent collisions) to keep my bird friends alive. Get ready for spectacular birding!
Screenshot of the birdcast migration dashboard, found at birdcast.info, showing a map of the continental United States colored by migration intensity, with a large portion of the eastern US, from Texas to souther Ohio, lit up white in the highest intensity color. The prediction says that 378 million birds are predicted to be in the air tonight, the night of April 28th 2025.
