Occurrence of bacterivory in Cryptomonas, a common freshwater phytoplankter
Abstract
Bacterivory was detected by incorporation of 0.57 μm diameter, fluorescent polystyrene beads and fluorescently labeled bacteria (FLB) in two cultured species of Cryptomonas (C. ovata and C. erosa), and a population of Cryptomonas sp in a humic, mesotrophic lake. Rates of ingestion and clearance were very low, and similar for the cultures and the in situ population. The in situ population incorporated 0.7-1.7 bacteria cell-1 h-1, thereby ingesting 0.3%-2.0% of the total bacterial numbers present in the water per day, and receiving less than 2% of its carbon content per day through bacterivory. Thus, bacterivory by Cryptomonas was quantitatively important neither as a sink for bacterial biomass, nor as a carbon source for the algal cells. Possibly, it served in the uptake of essential nutrients.

“The calculated ingestion rate for the flagellates (1.2 MPs cell−1 h−1) was consistent with that reported for Cryptomonas ovata and C. erosa (0.3–2.57 MPs cell−1 h−1) exposed to 0.57 μm polystyrene microspheres in culture conditions designed to optimize phagotrophy (Tranvik et al., 1989).”

In the citing paper
“Generally, in the environment cryptomonads ingest bacteria, but in laboratory conditions, the ingestion of MPs has been reported in the mixotrophic species Cryptomonas ovata and C. erosa exposed to 0.57 µm diameter polystyrene beads (Tranvik et al., 1989).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
