#ClimateChange is shortening the #SeaIce season in the Western Antarctic Peninsula. While ice cover affects the quantity of #macroalgae, Oswalt et al. found it didn't impact the nutritional quality of 4 WAP species collected in autumn. Read the study: doi.org/10.1111/jpy.13…

Over 30,000 tons of toxic aniline are released into aquatic ecosystems each year. Dong et al. recently discovered that Chlamydomonas reinhardtii can detoxify the pollutant and identified the enzyme responsible for its transformation. Learn more: doi.org/10.1111/jpy.13…

Female Saccharina japonica sporophytes may become diploid and develop sori. However, Li and Pang found no sori development when they cultivated 16 haploid and 46 diploid male sporophytes Is sori formation inherited maternally in this brown alga? doi.org/10.1111/jpy.13…

Climate change impacts kelp abundance, but are these brown algae threatened in other ways? Starko et al. compared two #kelp species in Barkley Sound to surveys from the 80s and found shifts in age structure. Read how this could affect ecosystem function: doi.org/10.1111/jpy.13…

The April issue of #JPhycol is available online! This issue features invasions in experimental #phytoplankton communities, reference genomes for 3 #diatom species, and the role of #microcystin in surviving #nitrogen starvation. Read the articles here: tinyurl.com/jphyApr25

In this #Algae Highlight, Carlot emphasizes Galobart et al.'s success in improving O2 production, pH regulation, and biomass in a restored macroalgal forest. Learn why long-term monitoring of functional indicators is essential for restoration projects: doi.org/10.1111/jpy.70…

Invasions by #cyanobacteria are harder to observe than those of larger organisms, but easier to study in labs. See how strain and temperature shaped invasion success when Weithoff & Stefan introduced Raphidiopsis raciborskii to phytoplankton communities: doi.org/10.1111/jpy.13…

Assembling #diatom genomes is challenging due to their high repetitive DNA content. Roberts and Alverson used long-read #sequencing to double the number of reference genomes available for #freshwater diatoms. Read their #GenomeResource paper here: doi.org/10.1111/jpy.13…

6 Dictyota species were recognized in Korea in 2022. Using marker gene sequencing and morphology, Vieira et al. corrected misidentifications and described 3 new species of the #seaweed, updating the list to 7. Check out their key to Korean #Dictyota here: doi.org/10.1111/jpy.70…

Reproductive cycles of #kelp are critical to restoration and cultivation efforts, but current monitoring methods are costly. Ward et al. showed the potential of #eDNA to monitor seasonal variation in Macrocystis pyrifera zoospore levels. Read the study: doi.org/10.1111/jpy.70…

#Dinoflagellate species may have 2 names—1 for the fossil cyst, 1 for the living stage. Huang et al. show the diversity of living taxa linked to cysts may be underestimated. Read how they germinated Spiniferites cysts to identify a new Gonyaulax species: doi.org/10.1111/jpy.70…

Alaska’s commercially and ecologically important #kelp might be threatened by glacial melt-induced hyposaline stress. Farrugia Drakard et al. found that impacts on early stages of bull and ribbon kelp varied by both species and population. Read the study: doi.org/10.1111/jpy.70…

Since 1853, Tryblionella have alternated between their own genus and Nitzschia. Olszyński et al. used SEM and molecular phylogeny to confirm that the #diatom genus is taxonomically distinct, though not currently monophyletic. Check out the micrographs: doi.org/10.1111/jpy.70…

Plastids are important for photosynthesis and adaptation in algae. Tang et al. sequenced the plastid genome of Pyropia katadae and compared it with 12 others from the Bangiales. Discover what they learned about the evolution of these genomes in #RedAlgae: doi.org/10.1111/jpy.70…

Happy #SeaweedDay! These red, green, and brown #algae play important roles in supporting marine habitats, mitigating climate change, and providing food. Over the next week, we will share 5 of the most highly-cited #seaweed papers published in #JPhycol over the years.

Harley et al. (2012) reviewed the effects of climate change on #seaweed populations, communities, and ecosystems. They also suggested research priorities to address unknowns that limited predictions a decade ago. Revisit the paper: doi.org/10.1111/j.1529… #SeaweedDay

Chopin et al. (2002) advocated for integrating #seaweed into fish and shrimp #aquaculture systems. Seaweed can help remediate nutrient-rich aquaculture effluent while increasing profitability. Read more about the benefits of this practice: doi.org/10.1046/j.1529… #SeaweedDay

Davison and Pearson (1996) reviewed stress tolerance in intertidal #seaweeds and found limited research on the mechanisms for their survival. They hoped for a "surfeit" of information on the topic in 25 years' time. Have we made progress? doi.org/10.1111/j.0022… #SeaweedDay

Hafting et al. (2015) surveyed the history of #seaweed cultivation and suggested improved cultivars and quality control were needed to enter the bioactive compound market. Has this functional seaweed industry flourished in the past decade? doi.org/10.1111/jpy.12… #SeaweedDay

Steinberg and de Nys (2002) found few detailed examples of chemically mediated interactions between #seaweeds and the many organisms that colonize them. Has a multidisciplinary approach to chemical ecology improved our understanding since? doi.org/10.1046/j.1529… #SeaweedDay
