Traits of five Symbiodinium genotypes measured at three different nitrogen levels

Abstract:

Replicates of each Symbiodinium genotype were grown in low (25mg/L), medium (75mg/L), or high (150mg/L) nitrogen environments, after which were measured physiological parameters, including the number of cells, quantum yield, variable fluorescence, and chlorophyll content.

Description

Methods & Sampling

Cultures initially isolated from Antillogorgia bipinnata coral colonies collected at Looe Key ( N 24° 32.973' W 81° 22.849; cultures 08-0689.4, 08-0689.6, 08-0691.1) in 2008 and the middle keys new Tennessee Reef (N 24° 45.150' W 81° 45.275'; cultures 13-121, 13-126) in 2013. Culture isolations were performed in the Coffroth lab, University at Buffalo. Physiological measurements were measured in the terHorst lab, California State University, Northridge. Quantum yield and fluorescence yield were measured in an AquaPen-C (Photon Systems Instruments). Chlorophyll concentration was quantified in a Triology Fluorometer. Culture growth rates were quantified by visual counts under a microscope at the beginning and end of the experiment. See Bayliss et al (2019) for further details and results.

Instruments

Fluorescence Microscope

Supplied Name: microscope

Supplied Description:

Used to count cells for growth rate calculations.

Instrument Type

Generic Name: Fluorescence Microscope

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB06/

Generic Description:

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.

Fluorometer

Supplied Name: Trilogy Laboratory Fluorometer

Supplied Description:

Used to measure chlorophyll concentrations.

Instrument Type

Generic Name: Fluorometer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/113/

Generic Description:

A fluorometer or fluorimeter is a device used to measure parameters of fluorescence: its intensity and wavelength distribution of emission spectrum after excitation by a certain spectrum of light. The instrument is designed to measure the amount of stimulated electromagnetic radiation produced by pulses of electromagnetic radiation emitted into a water sample or in situ.

Fluorometer

Supplied Name: AquaPen-C (Photon Systems Instruments)

Supplied Description:

Used to measure quantum yield and fluorescence yield.
