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 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 کاملLong Term Decline of Zostera Marina in Long Island
A long-term decline of Zostera marina has occurred throughout the western and central portions of Long Island Sound. Currently, Eelgrass is predominant in Fishers Island Sound and the nearshore zone from New London to East Lyme. Eelgrass is present in the mouth of the Connecticut River but the population size and distribution are not known. The only extant population located west of this river ...
متن کاملFacilitation of seagrass Zostera marina productivity by suspension-feeding bivalves
Seagrasses and suspension feeders are both critical ecosystem engineers in estuaries. Seagrass beds are important structural habitats, and suspension feeders, when abundant, can regulate phytoplankton densities. Furthermore, there may be mutual facilitation of growth and recruitment between seagrasses and suspension-feeding bivalves. In a series of mesocosm experiments, the effects of environme...
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...
