Meristematic oxygen variability in eelgrass (Zostera marina)
We examined the variability in oxygen content of meristematic tissues in eelgrass in order to evaluate its potential role in events of sudden mass mortality within eelgrass beds. Oxygen content within intact eelgrass plants could be described by use of microelectrode techniques at high temporal and spatial resolution in the laboratory and in the field. Under both situations, the meristematic ox...
متن کاملSeed production from the mixed mating system of Chesapeake Bay (USA) eelgrass (Zostera marina; Zosteraceae).
In monoecious plants, gametes can be exchanged in three ways: among unrelated genets (outbreeding), with close relatives (inbreeding), or within individuals (geitonogamous selfing). These different mating systems may have consequences for population demography and fitness. The experiment presented herein used artificial crosses to examine the mating system of Chesapeake Bay, Virginia, USA eelgr...
متن کاملStructure and properties of fibres from sea-grass ( Zostera marina )
This paper presents results from a study of fibres extracted from Zostera marina eel-grass collected from the Baltic coast. This species of sea-grass is shown to contain small diameter (around 5 μm) fibres composed of ∼57% cellulose, ∼38% of non-cellulosic polysaccharides (mainly xylan) and ∼5% of residual matter so-called Klason lignin. This composition is quite different to that of commonly u...
متن کاملGenetic relatedness influences plant biomass accumulation in eelgrass (Zostera marina).
In multispecies assemblages, phylogenetic relatedness often predicts total community biomass. In assemblages dominated by a single species, increasing the number of genotypes increases total production, but the role of genetic relatedness is unknown. We used data from three published experiments and a field survey of eelgrass (Zostera marina), a habitat-forming marine angiosperm, to examine the...
متن کاملCoexistence between Zostera marina and Zostera japonica in seagrass beds of the Seto Inland Sea, Japan
Background: There have been many studies on the growth conditions of Zostera marina and Zostera japonica, but few studies have examined how spatial and temporal factors affect growth in established seagrass beds or the distribution range and shoot density. This study aims to clarify the factors that determine the temporal and spatial distribution of Zostera marina and Zostera japonica in the Se...
