Instrument: Microscope-Fluorescence
Instruments that generate enlarged images of samples using the phenomena of fluorescence and phosphorescence instead of, or in addition to, reflection and absorption of visible light. Includes conventional and inverted instruments.
The reactors were monitored daily for 12-15 days to ensure constant conditions, thus minimizing predator: prey isotopic mismatch, and samples were taken for cell abundances and biovolumes using an Elzone counter and epifluorescence microscopy.
