Doliolids have a unique ability to impact the marine microbial community through bloom events and high filtration rates. Their predation on large eukaryotic microorganisms is established and evidence of predation on smaller prokaryotic microorganisms is beginning to emerge. We studied the retention of both eukaryotic and prokaryotic microbial taxa by wild-caught doliolids in the northern California Current system. Doliolids were collected during bloom events identified at three different shelf l...
Show moreSamples were collected during daylight from the R/V Atlantis (AGOR-25) along the Newport Hydrographic (NH) Line at station “NH5” (N 44° 39.084’, W 125° 7.151’) on July 22nd as well as along the Trinidad Head (TR) Line at stations “TR1” (N 41° 3.467, W 124° 16.016) and “TR3” (N 41° 3.448, W 124° 26.7) on July 17th and 19th, respectively.
Doliolids were sampled using a modified coupled Multiple Opening and Closing Net and Environmental Sensing System (MOCNESS). Doliolids were rinsed three times with 0.2 µm filtered seawater to remove unattached microbes, collected in a 1-mL sterile bead-beater tube containing 0.55- and 0.25-mm beads, and then frozen at -80 °C.
