Abstract:
Eelgrass shoots (Zostera marina) from Rimouski, QC, were exposed in July 2020 to a natural gradient of light intensity, ranging from 6 to 860 µmol photons/m²/s, to assess the species' capacity to respond to light attenuation. After 25 days of light exposure, pigment content was quantified using the second leaf of each shoot. Chlorophyll a, chlorophyll b, and total cerotenoids were extracted and quantified following Lichtenthaler's (1987) method.
