Nitrogen fixation in the rhizosphere of marine angiosperms
Marine Biology, 1972High rates of acetylene reduction were observed in systems containing excised rhizomes of the Caribbean marine angiosperms Thalassia testudinum, Syringodium filiforme and Diplanthera wrightii, and the temperate marine angiosperm Zostera marina. For 4 plant and plant-sediment systems the ratio of acetylene reduced/N2 fixed varied from 2.6 to 4.6. For T.

Photosynthesis and photorespiration of marine angiosperms
Aquatic Botany, 1989Abstract The marine angiosperms, or seagrasses, constitute a small but important plant group, common to many coastal habitats. In spite of their high productivity within near-shore ecosystems, the photosynthetic mechanisms of these plants have received relatively little investigation.

An underlying mechanism of qE deficiency in marine angiosperm Zostera marina
Photosynthesis Research, 2021Non-photochemical quenching (NPQ) of photosystem II (PSII) fluorescence is one of the most important protective mechanisms enabling the survival of phototropic organisms under high-light conditions. A low-efficiency NPQ, characterized by weak NPQ induction capacity and a low level of protective NPQ, was observed in the marine angiosperm Zostera marina,

Journal of Chemical Ecology, 2013
This review examines the state of the field for chemically mediated interactions involving marine angiosperms (seagrasses, mangroves, and salt marsh angiosperms). Small-scale interactions among these plants and their herbivores, pathogens, fouling organisms, and competitors are explored, as are community-level effects of plant secondary metabolites. At

Inorganic carbon utilization in marine angiosperms (seagrasses)
Australian Journal of Plant Physiology, 2002The mechanisms by which marine angiosperms, or seagrasses, utilize external inorganic carbon (Ci) include, in addition to uptake of CO2 formed spontaneously from HCO3–: (i) extracellular carbonic anhydrasemediated conversion of HCO3– to CO2 at normal seawater pH, or in acid zones created by H+ extrusion, and (ii) H+-driven utilization (direct uptake ...

Ecological Indicators, 2020 Marine macrophytes (macroalgae and angiosperms) were defined as one of the biological quality elements to assess the ecological quality status of transitional and coastal waters by the European Water Framework Directive (WFD, 2000/60/EC).

Somatic chromosome numbers of 2n = 20 are reported for all eight species of AustralianPosidonia: P. angustifolia, P. australis, P. coriacea, P. denhartogii, P. kirkmanii, P. ostenfeldii, P. robertsonae, andP. sinuosa. All species apparently have five larger and five smaller pairs of chromosomes.

Disturbance-related heterogeneity in the seed banks of a marine angiosperm
Journal of Ecology, 2000Summary 1 Patterns in the distribution of seeds of the marine angiosperm Halodule uninervis were described over spatial scales ranging from a few centimetres to meadows separated by more than 120 km along the north‐eastern coast of Queensland, Australia. Separate surveys examined how seed bank densities were related to: (i) the distribution of male and

Polymorphic microsatellite loci for the marine angiosperm Cymodocea nodosa
Molecular Ecology Notes, 2004AbstractThe seagrass Cymodocea nodosa (UCRIA) Ascherson represents a good model to assess the relative contribution of clonal and sexual reproduction to genetic structure in marine plant populations. Seven microsatellite loci with repeat units consisting of one trinucleotide, four simple dinucleotides and two complex dinucleotides are described here ...
