Oxic microshield and local pH enhancement protects Zostera muelleri from sediment derived hydrogen sulphide.
Kasper Elgetti Brodersen,Daniel A. Nielsen,Peter J. Ralph,Michael Kühl,Michael Kühl,Michael Kühl +5 more
TL;DR: High belowground H₂S concentrations at the tissue surface correlated with the inability to sustain the protecting oxic microshield around the meristematic regions of the rhizome, and increased pH levels in the immediate rhizosphere of Z. muelleri were found, which may contribute to further detoxification of H⁂S through shifts in the chemical speciation of sulphide.
Journal ArticleDOI
Sedimentary Factors are Key Predictors of Carbon Storage in SE Australian Saltmarshes
Jeffrey J. Kelleway,Jeffrey J. Kelleway,Neil Saintilan,Peter I. Macreadie,Peter I. Macreadie,Peter J. Ralph +5 more
TL;DR: In this article, the relative importance of geomorphic and vegetation attributes to variability in the belowground carbon stocks of saltmarshes in New South Wales (NSW), southeast Australia was investigated.
Journal ArticleDOI
Morphological, growth and meadow characteristics of the seagrass Posidonia sinuosa along a depth-related gradient of light availability
TL;DR: It is proposed that the reduction in shoot density partially alleviates the effects of self-shading and permits comparable leaf growth rates across the depth range, and is the most sensitive of the morphological characteristics measured here.
Journal ArticleDOI
Short-term response and recovery of Zostera capricorni photosynthesis after herbicide exposure
TL;DR: In this paper, the effect of pulsed exposure to catastrophic levels of the herbicides Atrazine, Diuron and Irgarol 1051 on the seagrass Zostera capricorni Aschers was assessed in both laboratory and field experiments.
Journal ArticleDOI
Photosynthetic response of halophila ovalis (r. br.) hook, f. to combined environmental stress
TL;DR: In this article, it was shown that thermal, elevated-light or osmotic stress increases the sensitivity of Halophila ovalis to any of the other stress factors, while combining of stresses showed an additive effect in comparison to individual stress responses.
