When shifts in Arctic pond #diatoms were first described, we knew little about Northern #GreatLakes. Now it's clear these deep lakes show strikingly similar responses to warming. Smol et al. show how algae signal #ClimateChange in this #JPhycol Perspective

"This work is extremely promising because it shows the ease with which preliminary screening for antivirals from cyanobacteria and microalgae can be done in a lab that is not necessarily equipped with the type of infrastructure needed to work with pathogenic viruses." (5/5)

COVID-19 highlighted the need for new treatments against viral infections. Could #cyanobacteria represent an untapped source of #antiviral activity? Read about how students from @jin_oceanvir’s lab tested strains of cyanobacteria against viruses: (1/5)

Exploring early #diatom #evolution? Our October cover features diatoms in the Cretaceous Diatom Database. @KarolinaBrylka et al. compiled fossil data to create a list of 721 species and their corresponding age of occurrence. See the database here:

The October issue of #JPhycol is out! Check out this link to read about algae as first responders to #ClimateChange, a new tool to investigate early #diatoms, novel species of #cyanobacteria from India, and more:

Who needs sunglasses 😎 when you’ve got xanthophylls 🟡? Despite lacking a xanthophyll cycle, Huang et al. found these pigments help Neoporphyra haitanensis thrive under light stress. Read about the red alga’s adaptations to life in the intertidal zone:

Nori aquaculture in China faces a challenge: stay put as sea temperatures rise or move north, exposing the red algae to high light intensity and oxidative stress. Read how Li et al. genetically transformed Pyropia yezoensis to improve stress resistance:

Diatoms can indicate past lake conditions, but many regions lack the calibration data for interpretation. New work by Griffiths et al. improves #biomonitoring by analyzing species responses to environmental gradients in over 150 Canadian lakes! Read on:

How do you tell cryptic #cyanobacteria apart when barcoding lacks species-level resolution? @dvorikus et al. suggest that population genomics can delimit challenging taxa. Discover how they identified two new Laspinema species in this #JPhycol article:

RT @bernalocean: The last chapter of my #PhD is now published in @JPhycology! We explored biotic and abiotic interactions around the initia…

Phaeocystis globosa, a haptophyte, forms giant colonies in tropical waters, tinting the ocean off Phan Thiet, Viet Nam. Meng et al. collected colonies up to 15 mm to explore what drives giant versus normal growth. Read more:

Why didn’t the #diatom cross the ocean? @ErinBorbee et al. reveal how ocean currents limit dispersal, transport nutrients, and influence protist diversity across the Indo-Pacific 🌊. Learn more:

Can you spot the difference? 🧬 Crépeault et al. found that coccoid Pycnococcus and scaly, flagellated Pseudoscourfieldia share nearly identical organellar genomes. Find the taxonomic revisions (including a new #prasinophyte class) proposed here:

As terrestrial forests change colour, underwater kelp forests are changing too! 🍂 New research by @KalaniCarlson et al. shows increased release of dissolved organic carbon by incubated #kelp during autumn. Find out what this means for the carbon cycle:

Seaweed #phenolics have therapeutic potential, but conventional extraction methods often miss cell wall-linked compounds. In this #JPhycol article, Liu et al. optimized ultrasound-assisted extraction to maximize phenol yield from #Sargassum carpophyllum:

Watch chloroplasts migrate to a wound site after a red algal cell is punctured! Hong et al. used time-lapse imaging to reveal that calcium influx, ROS signalling, and microtubules are key for single-cell repair in Griffithsia monilis. Read the study here:

How do pennate #diatoms regulate their orientation and sedimentation? Sourisseau et al. found varying sinking rates among Pseudo-nitzschia species, with chains of Pseudo-nitzschia pungens cells following flexible fiber dynamics. Learn more:
