Low-Temperature Limits for Motility in a Eukaryotic Cell: Ice-Gliding Diatoms in Arctic Ice
Introduction: Cold-Weather Motility and the Arctic Microbial World In the harsh Arctic environment, ice-entrapped diatoms persist and thrive far from temperate waters. These ice-dwelling phytoplankton navigate a frozen maze, accessing light and nutrients that would otherwise be out of reach. Our study presents direct cellular observations of diatoms embedded in ice and demonstrates a remarkable…

Low Temperature Limits for Motility in Arctic Ice Diatoms
Overview: Arctic ice diatoms and ice gliding In the harsh Arctic environment, ice-dwelling diatoms endure extreme cold, variable brine pockets, and constrained liquid pathways within the ice. Our study provides direct cellular observations of these microorganisms embedded in ice and reveals a previously undocumented ice-gliding ability that helps them navigate the ice matrix to reach…
