AI Article Synopsis
- Photosynthetic cryptophytes are important protists in freshwater ecosystems, especially contributing to spring phytoplankton blooms.
- Bloom collapse is mainly influenced by environmental changes and grazing, but the impact of viruses on this process in freshwater has been less understood.
- This study identified and characterized a virus that affects cryptophyte populations, representing a significant group of giant viruses found globally in freshwater environments.
Article Abstract
Photosynthetic cryptophytes are ubiquitous protists that are major participants in the freshwater phytoplankton bloom at the onset of spring. Mortality due to change in environmental conditions and grazing have been recognized as key factors contributing to bloom collapse. In contrast, the role of viral outbreaks as factors terminating phytoplankton blooms remains unknown from freshwaters. Here, we isolated and characterized a cryptophyte virus contributing to the annual collapse of a natural cryptophyte spring bloom population. This viral isolate is also representative for a clade of abundant giant viruses (phylum Nucleocytoviricota) found in freshwaters all over the world.

In New Zealand, the frequency and intensity of marine heatwaves (MHWs) and blooms of the harmful algal species, Alexandrium pacificum, are increasing in areas where there are natural reefs and commercial farms of the mussel, Perna canaliculus. In this study, we assessed the whole organism, tissue and molecular-level response of juvenile (spat) P. canaliculus exposed to these abiotic and biotic stressors, alone and together.

Heat shock proteins (Hsps) are highly conserved molecular chaperones with essential roles against biotic and abiotic stressors. A large set of co-chaperons comprising J-domain proteins (DnaJs) regulate the ATPase cycle of Hsp70s with Hsp90s, together constituting a dynamic and functionally versatile network for protein folding/unfolding and regulation. Marine bivalves could accumulate and tolerate paralytic shellfish toxins (PSTs), the well-noted neurotoxins generated during harmful algal blooms.

Beauvoir, Ernaux, and Me: On Age, Disability, and Dying Well.

Can the fraught relation between disability and aging ever become untangled? What is the place of the catastrophically disabled in a time when giving voice and being seen are significant lodestars of political activism? And what becomes of the caregivers, who often labor in silence, and who hope to work well enough just to get through another day? This essay draws on the memoirs of Simone de Beauvoir, Annie Ernaux, Amy Bloom, and my own experiences to show the complicated imbrications of age, disability, and caretaking. I attempt to demonstrate through these experiences that age and disability, which appear to be intimately woven together, are oftentimes misleadingly connected. I suggest that an ethic of vulnerability, rather, is a more useful heuristic that avoids collapsing the categories of age and disability together.

Article Synopsis
- - Members of the phylum Verrucomicrobiota are important to ecosystems but often go unrecognized in databases due to their low abundance and difficulty in isolation.
- - This study focused on the family MB11C04 found in North Sea spring blooms, revealing that their populations increase towards the end of these blooms and identifying their capability to break down complex sugars.
- - Two new genera and species were introduced (Seribacter and Chordibacter), along with a proposed new family name (Seribacteraceae), highlighting the ecological roles and metabolic potential of these microorganisms.
