Journal ArticleDOI
Relative effects of nutrient enrichment and grazing on epiphyte-macrophyte (Zostera marina L.) dynamics
TL;DR: There was little epiphyte response to treatment during the fall, a result possibly of high ambient nutrient concentrations and low grazing pressure, and the relative influence of epipHYtes on macrophyte production may have been related to seasonally changing water temperature and macrophytes requirements for light and inorganic carbon.
Journal ArticleDOI
Seasonal pulses of turbidity and their relations to eelgrass (Zostera marina L.) survival in an estuary
TL;DR: Late spring, month-long pulses in turbidity, such as measured here can account for the loss of transplanted vegetation and, potentially, explain lack of successful recruitment into formerly vegetated upriver sites.
Journal ArticleDOI
Epiphyte-grazer relationships in seagrass meadows: Consequences for seagrass growth and production
TL;DR: Much of the literature on epiphytegrazer relationships in seagrass meadows is summarized and insights from mathematical modeling simulations of these relationships for a Chesapeake BayZostera marina meadow are provided.
Journal ArticleDOI
Seasonal variations in eelgrass (Zostera marina L.) responses to nutrient enrichment and reduced light availability in experimental ecosystems
TL;DR: The results suggest that it is principally light availability which governs seagrass growth in moderately nutrient enriched regions of the Chesapeake Bay, and in systems such as the York River, given adequate grazer densities, observed levels of nutrient enrichment are unlikely to cause excessive epiphyte loads and subsequent seagRass declines.
Journal ArticleDOI
Spatial and temporal characteristics of nutrient and phytoplankton dynamics in the York River Estuary, Virginia: Analyses of long-term data
TL;DR: In this article, the authors investigated general patterns of phytoplankton and nutrient dynamics, and identified major factors controlling those dynamics in the York River Estuary, Virginia.
