Effect of epiphytes on eelgrass photosynthesis

Aquatic Botany, 1977
The effect of epiphytes on eelgrass photosynthesis was measured at varying light intensities and HCO3− concentrations by means of the 14C-technique. Eelgrass was collected in Vellerup Vig, Denmark during October and November 1975. The epiphytes, mainly diatoms of the species Cocconeis scutellum Ehr., formed a crust several layers thick on the older ...

Seasonality of eelgrass, epiphyte, and grazer biomass and productivity in subtidal eelgrass meadows subjected to moderate tidal amplitude

Aquatic Botany, 1997
Abstract Epiphyte and eelgrass ( Zostera marina L.) biomass and production and herbivorous gastropod ( Lacuna spp.) biomass were measured monthly for two years in a subtidal meadow subjected to moderate tidal amplitude in the San Juan Islands, WA, USA.

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.

Overgrowth of eelgrass by the invasive colonial tunicate Didemnum vexillum : Consequences for tunicate and eelgrass growth and epifauna abundance

Journal of Experimental Marine Biology and Ecology, 2015
Abstract The invasive tunicate Didemnum vexillum has become widely distributed in estuaries in western North America over the past decade. It has recently invaded eelgrass meadows in a central California estuary, growing directly on shoots and rhizomes.

Decomposition processes of eelgrass,Zostera marina L.

Hydrobiological Bulletin, 1982
In Lake Grevelingen decomposition of eelgrass was studied in the field with the litter bag method from July 1977 till February 1978. After 6 months only 6% refractory matter remained in the bags. Under aerobic conditions the decomposition of eelgrass is completed within one year. The organic fraction decreased from 80 to 55%.

Reproduction of annual eelgrass: Variation among habitats and comparison with perennial eelgrass (Zostera marina L.)

Aquatic Botany, 1987
Abstract The variation in reproductive potential of annual eelgrass was examined along a continuous gradient on an extensive mudflat bordering on and sloping down from the shore (Eastern River) and in a habitat mosaic in a salt marsh (Petpeswick Inlet) in Nova Scotia. Spathe and flower production as well as plant density were compared among habitats.

Eelgrass under Arctic Winter Ice

Nature, 1969
EELGRASS (Zostera marina L.), a marine angiosperm which grows on the Pacific coast of North America from the Gulf of California to the Chukchi Sea1, has been found living under the winter sea ice in Safety Lagoon, an embayment of the Bering Sea near Nome, Alaska.
