Impact of light limitation on seagrasses (2007, background): “For example, within the T. testudinum canopy, pigment content, chlorophyll fluorescence, absorptance and effective and maximum quantum yields all decline from the base to the apex of the leaf (Durako and Kunzelman, 2002; Enríquez et al., 2002; Enríquez, 2005).”
Daily variation patterns in seagrass photosynthesis along a vertical gradient (2003, methodology): “…appear to have 2 common features: the considerable differences between them (from 0.44 in Zostera marina to 0.78 in Thalassia testudinum; Beer et al. 1998, Durako & Kunzelman 2002) and the fact that all of them are lower than the standard value of 0.84 originally reported for terrestrial plants.”
Photosynthetic responses of seven tropical seagrasses to elevated seawater temperature (2006, background): “Seagrasses in shallow pools of water are not only exposed to elevated temperatures during midday sun exposure, but they are also subject to desiccation during low tidal periods and high PAR and UV radiation (Dawson and Dennison, 1996; Durako and Kunzelman, 2002).”
Morphological, growth and meadow characteristics of the seagrass Posidonia sinuosa along a depth-related gradient of light availability (2007, background): “This response maximises exposure of the lower mid-sections of the leaves, which are frequently the most highly photosynthetic (Ralph et al. 1998, Durako & Kunzelman 2002) and the most consistently epiphyte-free portion of the seagrass leaves (Dalla Via et al. 1998).”
Tropical seagrass species tolerance to hypersalinity stress (2007, methodology): “The Fv/Fm ratio has been applied as an indicator of seagrass stress, with an optimal range for seagrass approximately 0.7– 0.8 (Ralph, 1999; Beer et al., 2001; Durako and Kunzelman, 2002), slightly lower than C3 terrestrial plants (0.83; Björkman and Demmig, 1987).”
The Use of the Fluorescence Signal in Studies of Seagrasses and Macroalgae (2010, background): “In general, large spatial variability within the same individual has been recognized (e.g., Durako and Kunzelman 2002; Enriquez et al. 2002; Turner and Schwarz 2006; Colombo-Pallota et al. 2006; Strain et al. 2006; Belshe et al. 2007), due to intrinsic components related to the structural complexi”
