    Description: Abundances (percent cover, counts or biomass) of rocky mid-intertidal macro-species measured through a multi-factorial in situ experiment of 14 months in 2012-2013 in Sainte-Flavie, Québec, Canada (48°37'42.5″ N, 68°11'55.7″ W). Using 0.25-m² plots, we ran an in situ one-pulse experiment (removal of all materials to bare rock and then burning of the surface) followed by a full orthogonal factorial design of three press-type disturbances or stresses: grazer reduction, canopy removal, and nutrient enrichment. We evaluated percentage cover visually. Counts and biomass were obtained destructively at the end of the experiment. For further details, refer to our paper (https://doi.org/10.1002/ecs2.2467).

    Photosynthetic efficiency and capacity of intertidal temperate seagrass Zostera marina from Rimouski, QC, Canada, under a light intensity gradient (2022)

    Description: 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 5 and 25 days of light exposure, photosynthetic responses were examined using PAM (Pulse Amplitude Modulated) fluorometry. Rapid Light Curves (RLC) were carried out on the second leaf of each shoot and were used for extraction of photosynthetic parameters, such as the photosynthetic efficiency (alpha), the photosynthetic capacity (ETRmax), and the onset of light saturation of the photosynthetic apparatus (Ek).
