Data from: Population characteristics of a large whale shark aggregation inferred from seawater environmental DNA
Population genetics is essential for understanding and managing marine ecosystems, but sampling remains challenging. We demonstrate that high-throughput sequencing of seawater environmental DNA can provide useful estimates of genetic diversity in a whale shark (Rhincodon typus) aggregation. We recover similar mitochondrial haplotype frequencies in seawater compared to tissue samples, reliably placing the studied aggregation in a global genetic context and expanding the applications of environmental DNA to encompass population genetics of aquatic organisms.

Reversal data during aggregation of Myxococcus xanthus
<p>Reversal data of the bacterium Myxococcus xanthus during<br>the formation of aggregates under starvation conditions. The data is<br>separated into two files based on whether an individual bacterium is<br>moving towards or away from the nearest aggregate. Space is measured<br>in micrometers and time in minutes. Each file includes the length of<br>time before the bacteria changes directions, the speed during that<br>period, the distance from the nearest aggregate, the bearing angle<br>with respect to that aggregate, and the local cellular density when a<br>bacterium starts moving in a new direction.<br><br>This data was obtained by processing images from the Welch Lab at<br>Syracuse University. These images are published in "Cell behaviors<br>underlying Myxococcus xanthus aggregate dispersal" (DOI:<br><a href="https://doi.org/10.1128/msystems.00425-23" target="_blank" rel="noopener noreferrer">https://doi.org/10.1128/msystems.00425-23</a>).

Data From: Active sinking particles: Flow and transport dynamics due to sessile suspension feeders on sinking aggregates
<p>Sinking or sedimentation of biological aggregates plays a critical role in carbon sequestration in the ocean and in vertical material fluxes in waste-water treatment plants. In both these contexts, the sinking aggregates are "active," since they are biological hot-spots and are densely colonized by microorganisms including bacteria and sessile protists, some of which generate feeding currents. However, the effect of these feeding currents on the sinking rates, trajectories, and mass transfer to these "active sinking particles," has not previously been studied. Here we use a novel scale-free vertical-tracking microscope (a.k.a. Gravity Machine, Krishnamurthy et al. "Scale-free vertical tracking microscopy." Nature Methods (2020)) to follow model sinking aggregates (agar spheres) with attached protists (<em>Vorticella convallaria</em>), sinking over long distances while simultaneously measuring local flows. We find that activity due to attached \vortc causes significant changes to the flow around aggregates in a dynamic manner and reshapes mass transport boundary layers. Furthermore, we find that activity-mediated local flows along with sinking modify the encounter and plume cross-sections of the aggregate and induce sustained aggregate rotations. Overall our work shows the important role of biological activity in shaping the near-field flows around aggregates with potentially important effects on aggregate fate and material fluxes.</p>
