【 摘 要 】

During the late summer, the author sailed to the Antarctic South Shetland Islands to survey the microorganisms living in marine (tidal pools) and freshwater (moss saturated with snow melt) environmental niches. Equipped with a microscope to take video of samples within hours of collection to capture a pristine condition, the authors found a dense and diverse ecology that included species with unique patterns of locomotion. Capturing the organism's movement expedited identification, but it also showed the dynamic way each organism's mobility fit together like a puzzle to create a complex ecosystem.
