Nitrogen content of seeds of Zostera capricorni and Zostera marina

Aquatic Botany, 1992
Abstract The nitrogen (N) content of mature seeds of Zostera capricorni Aschers, was found by Kjeldahl analysis to be 1.70% of dry matter. The larger seeds of Zostera marina L. were analysed individually by the more sensitive Heraeus procedure. The mean seed N content of these seeds was 1.37% of dry matter (range 1.20–1.56%, standard deviation ...

Volatiles from Zostera marina

Phytochemistry, 1998
Abstract The essential oil from the shoots of the marine embryophyte, Zostera marina was prepared by simultaneous distillation-extraction. Volatile compounds in the oil were identified by GC and GC-mass spectrometry. The major constituents were phytol, hexadecanamide, octadecanamide, pentadecane, heptadecane, nonadecane, (8 Z , 11 Z ...

The Fungus on Zostera marina

Nature, 1934
THE fungus Ophiobolus halimus, which has recently been described as parasitic on Zostera marina L., has this summer been discovered on this plant in the British Isles. It has been found in several localities in Devon (Plymouth, Cawsand, River Yealm, Salcombe), the north coast of Guernsey and Lough Ine, Ireland. Dr. E. J. Butler has compared the British

THE WASTING DISEASE OF ZOSTERA MARINA

The Biological Bulletin, 1936
At the time that this study was begun, mid-summer, 1933, an epidemic, wasting disease had almost entirely destroyed the normally dense beds of the common marine eel-grass, Zostera marina, along the Atlantic coasts of North America and Europe. Since the plant is a prominent member of the shallow water community, sheltering a variety of larval and small ...

Wasting Disease of Zostera marina

Nature, 1934
In connexion with the various investigations into the local disappearance of the grass wrack1, it has been noticed that the smaller narrow-leaved form of Zostera marina has, in some cases, replaced the larger type. Attention was thus focused on this Z. marina var.

Eelgrass (Zostera marina) tolerance to anoxia

Journal of Experimental Marine Biology and Ecology, 2010
Abstract The tolerance of eelgrass (Zostera marina L.) to anoxia was assessed experimentally to evaluate the potential role of short-term anoxia on eelgrass performance. Eelgrass ramets (terminal leaf bundles with rhizomes and roots) were submerged in anoxic seawater for variable periods of time (0.5 to 48 h) at three temperatures (20, 25 and 30 °C ...

A Mycetozoan Parasite of Zostera marina

Nature, 1935
IN a previous note in NATURE1 we pointed out the association of a Labyrinthula-like organism with the wasting disease of the eelgrass along the American Atlantic coast. Since the publication of this announcement, we have performed a number of experiments in the laboratory and in the natural beds themselves, which indicate that this organism is a true ...

Benthic Infauna of Eelgrass, Zostera marina, Beds

Chesapeake Science, 1973
The infauna ofZostera beds in the Chesapeake Bay-York River estuary and Chincoteague Bay was sampled in March and July 1970 using a corer. Sediments were fine sand or very fine sand. Sorting of sediments varied from poorly sorted to moderately well-sorted and appeared to be positively correlated with the density ofZostera at the respective stations.

Nitrate reductase activity in Zostera marina

Marine Biology, 1988
Eelgrass (Zostera marina L.) has access to nutrient pools in both the water column and sediments. We investigated the potential for eelgrass to utilize nitrate nitrogen by measuring nitrate reductase (NR) activity with an in vivo tissue assay. Optimal incubation media contained 60 mM nitrate, 100 mM phosphate, and 0.5% 1-propanol at pH 7.0.
