Comparison of advanced methodologies for diatom identification within dynamic coastal communities

Pierce, E., Torano, O., Lin, Y., Schnetzer, A., & Marchetti, A. (2023, September 27). LIMNOLOGY AND OCEANOGRAPHY-METHODS, Vol. 9.

By: E. Pierce n, O. Torano*, Y. Lin*, A. Schnetzer n & A. Marchetti*

TL;DR: Overall, this study indicates that at the semi‐quantitative level of relative abundance measurements, FlowCam imaging and metabarcoding of the V4 region of the 18S rRNA gene yield comparable results with light microscopy but at the qualitative and quantitative levels, enumeration metrics diverge, and thus method selection and cross‐method comparison should be performed with caution.

Journal of Plankton Research, 27(10), 959–971.

By: A. Schnetzer* & D. Caron*

TL;DR: The copepod-protozoan trophic link appears to be a key factor structuring the planktonic microbial assemblage in the San Pedro Channel. (via Semantic Scholar)

2002 journal article

Active transport of particulate organic carbon and nitrogen by vertically migrating zooplankton in the Sargasso Sea

Marine Ecology Progress Series, 234, 71–84.

By: A. Schnetzer* & D. Steinberg

author keywords: zooplankton; vertical migration; gut evacuation rate; gut fluorescence; particulate organic carbon; particulate organic nitrogen; export flux; Sargasso sea; Bermuda Atlantic time-series study (BATS)
TL;DR: It is estimated that 71 to 85% of the migrant diet originated from non-plant material, which was included in estimates of active POC/PON export, and freshly released feces by migrators at depth could be a valuable food source for mesopelagic organisms. (via Semantic Scholar)

2002 journal article

Natural diets of vertically migrating zooplankton in the Sargasso Sea

Marine Biology, 141(1), 89–99.

By: S. A. & S. D.

TL;DR: The species-specific differences in the diets of these three migrating zooplankton suggest that an individual species approach is important in determining how feeding habits affect the structure of pelagic food webs and carbon cycling in the sea. (via Semantic Scholar)
