A very extreme and unusual presentation of pink-spot disease on a kelp spool

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

A small cunner (Tautogolabrus adspersus) peers through strands of sugar kelp (Saccharina latissima) in a lush kelp forest ecosystem on Cashes Ledge in the Gulf of Maine.

Kelp forests on the coast of Maine are in decline owing to rapid ocean warming and are being replaced by turf algae, which alter the ecosystem’s chemistry, hindering the recovery of kelp forests.

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.

Positive selection and relaxed purifying selection contribute to rapid evolution of sex-biased genes in green seaweed Ulva - BMC Ecology and Evolution Background The evolution of differences in gamete size and number between sexes is a cornerstone of sexual selection theories. The green macroalga Ulva, with incipient anisogamy and parthenogenetic ga...

Root hair lifespan is antagonistically controlled by autophagy and programmed cell death Root hairs are tubular tip-growing extensions of root epidermal cells that enhance root surface area for water and nutrient uptake. While mechanisms governing root hair fate, polarity, and tip growth ...

Qiangnan Feng (Nowack lab @moritznowack.bsky.social @psb-vib.bsky.social ) shows that cell-type specific elevated autophagy in root hairs extends their lifespan by suppressing premature senescence and age-induced programmed cell death www.biorxiv.org/content/10.1...

The people who produce this Mauna Loa atmospheric CO₂ record have a lab in Hilo, Hawaiʻi, about 50 miles (80 km) from the observatory. By closing the lab, it'll be really difficult to maintain the CO₂ observations.

We are searching for a postdoc in Marine Phytoplankton Metabolism and Carbon Storage! You'll get the chance to work in Belgium to combine high-throughput metabolomics and enzymes to study how microbes naturally sequester atmospheric carbon in organic marine molecules!
