| log in | [gut equal] - Microsphere counts from gut samples for equal microsphere concentration incubations (Collaborative Proposal: Are all cell surfaces the same? The effects of particle surface property on predator-prey interactions in the microbial loop) | Cell surface properties can strongly mediate microbial interactions with predators in soil and host-pathogen systems. Yet, the role of microbial surface properties in avoiding or enhancing predation in the ocean remains a research frontier. Appendicularians are globally abundant marine suspension feeders that capture marine microorganisms in a complex mucous filtration system. We used artificial microspheres to test whether the surface properties of prey particles influenced selection by the appendicularian, Oikopleura dioica . Across microsphere sizes (0.5, 1, 2 and 3 µm) and concentrations (~103-106 particles ml-1), which were varied to represent realistic microbial communities, carboxylate- and amine-modified particles were handled differently by the appendicularians. The carboxylate-modified particles were enriched in the gut while the amine-modified particles were enriched in the mucous filters, leading to different particle fates. \n\nThis dataset includes microsphere counts from appendicularian guts following feeding incubations with two microsphere sizes (for each functionalized microsphere) available in equal concentration.\n\ncdm_data_type = Other\nVARIABLES:\nIncubation (Unitless)\nDuration_min (Minutes)\nAnimal_ID (Unitless)\nC_1_um_gut (Count per gut)\nC_2_um_gut (Count per gut)\nA_1_um_gut (Count per gut)\nA_2_um_gut (Count per gut)\n | BCO-DMO | bcodmo_dataset_957150_v1 | ||||||||||||

Rays were spotted visually from a moving vessel and collected via a knotted seine net by encircling the animal and entangling it. Rays were brought aboard for measurements, photographs and tagging (Passive Integrated Transponder and CATS-CAM) and kept in a small plastic pool with ambient seawater. Once procedures were complete, rays were released on site, or brought to the Bermuda Aquarium for further examination.\n\ncdm_data_type = Other\nVARIABLES:\nCatch_ID (unitless)\nDate (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nAnimal_ID (unitless)\nDW (centimeter (cm))\nSL (centimeter (cm))\nTL (centimeter (cm))\nSex (unitless)\nMature (unitless)\nPIT (unitless)\nCATS_CAM_ID (unitless)\n | BCO-DMO | bcodmo_dataset_964473_v1 |
