To assess these rates, we conducted dilution experiments coupled to high-performance liquid chromatography and flow-cytometry in sub-Antarctic waters on and off Campbell Plateau, southeast of Aotearoa-New Zealand. Off the plateau, growth and grazing were closely balanced for all groups despite a two-fold difference between slow- and fast-growing groups. On Campbell Plateau, where HNLC conditions were alleviated, the balance was disrupted, mainly by the preferential growth of diatoms and green algae, which was stimulated beyond grazing. Our results expand the recognized ability of diatoms to escape grazing control to picoplanktonic green algae that also avoid grazing and contribute significantly to phytoplankton productivity and biomass accumulation.</p>","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"8 6","pages":"896-905"},"PeriodicalIF":7.8,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aslopubs.onlinelibrary.wiley.com/doi/epdf/10.1002/lol2.10355","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71416917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These large phenological changes were not associated with changing temperature, but they were associated with changes in top–down control by bivalve filter feeders as biological communities were restructured by (1) introduction of a non-native clam, and (2) a shift in atmospheric forcing of the NE Pacific.

Authors choose where to submit their articles from over 40,000 peer-reviewed scholarly journals (Johnson et al. &lt;span&gt;2018&lt;/span&gt;), and the journal publishing model is one consideration in their decision process. Journals published by the Association for the Sciences of Limnology and Oceanography (ASLO) have followed model 2 since 2015 when ASLO entered a partnership with Wiley, in part because of revenue sharing that expanded the capacity of this society to serve its authors and members. I use lessons learned from the ASLO publication experience to describe three benefits of the society-publisher model that you as an author might consider when deciding where to submit your next manuscript.&lt;/p&gt;&lt;p&gt;Scientific publishing is on a fast track toward fully open access journals where authors pay the publication cost. Authors are largely unaware that more than half of this publication cost goes from the publisher to ASLO. This publishing revenue constitutes 40% to 60% of ASLOs total annual revenue, depending on income from conferences. This revenue supports services and benefits provided by ASLO to its members and beyond. The most direct benefit is publication of ASLO's journals—one of the most valued functions of scientific societies for its members (Johnson et al. &lt;span&gt;2018&lt;/span&gt;). But many other benefits are enabled by this partnership, including ASLO operations and programs that target students, early career researchers (ECRs), and under-represented groups. Examples include:&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Meeting Travel Award&lt;/b&gt;” pays travel costs for student and ECR members to attend an ASLO meeting.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Raelyn Cole Editorial Fellowship&lt;/b&gt;” provides professional development for ECRs in publishing, peer review, and scientific writing.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Early Career Publication Honor&lt;/b&gt;” pays the publication cost of open-access articles authored by ECRs in need, including those from the global south.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Science Communication Internship&lt;/b&gt;” provides opportunities for graduate students to learn about science communication.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Global Outreach Initiative&lt;/b&gt;” assists members outside the U.S. in communicating aquatic science to non-technical audiences.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Multicultural Program&lt;/b&gt;” builds cohorts of connected students from under-represented groups and provides travel support to ASLO meetings.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Ecological Dissertations in the Aquatic Sciences&lt;/b&gt;” is a symposium that builds collaborations among recent PhD recipients.&lt;/p&gt;&lt;p&gt;The “&lt;b&gt;Amplifying Voices Webinar&lt;/b&gt;” series for Early Career Researchers from historically excluded groups.&lt;/p&gt;&lt;p&gt;Through their payment of publication fees, authors who","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"8 6","pages":"799-803"},"PeriodicalIF":7.8,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://aslopubs.onlinelibrary.wiley.com/doi/epdf/10.1002/lol2.10353","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71416914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrosomes have been recorded for at least two centuries, yet much remains unknown about their physiology, bloom mechanisms, and ecosystem impacts. Recent bloom reports prompt the question of whether frequencies or densities are increasing, and whether potential population changes are caused by ocean change. This review clarifies current information on pyrosome biology and ecology and explores apparent contradictions in habitat preferences and diel vertical migration (DVM). We posit that the dominant species, <i>Pyrosoma atlanticum</i>, may preferentially inhabit waters below 18°C and alter its DVM activity to maintain overall body temperature near this threshold.
