Photoadaptation and Growth of Zostera marina L (Eelgrass) Transplants Along a Depth Gradient

Photosynthetic and growth responses were assessed in Zostera marina L. transplants within and beyond the natural extent of an eelgrass meadow in Great Harbor, Woods Hole, MA. Transplant survival and rapid growth inshore of the shallow edge of the meadow (0.5 and 0.8 m water depth) indicated a periodic disturbance factor maintaining the shallow edge of the meadow.

ABSTRACT: Photosynthesis, biomass and growth characteristics of the temperate seagrass, Zostera marina L. (eelgrass), were examined in a meadow in Great Harbor, Woods Hole, Massachusetts during June and August, 1982. Underwater lamps and light shading screens were placed at shallow (1.3 m) and deep (5.5 m) stations to lengthen and shorten daily light periods.

The adaptive physiology of Zostera marina, L. (eelgrass) was investigated along a water depth gradient in order to assess the interactions of this prolific temperate seagrass with its environment. In situ and controlled-environment manipulations of light and sediment availability along with transplants beyond and within the eelgrass meadow were conducted.

Photosynthetic responses of the temperate seagrass, Zostera marina L., were examined by manipulations of photon flux density in an eelgrass bed in Great Harbor, Woods Hole, MA during August 1981. Sun reflectors and light shading screens were placed at shallow (1.3 m) and deep (5.5 m) stations in the eelgrass bed to increase (+35% to +40%) and decrease (-55%) ambient photon flux densities.
