Predicting effects of ocean warming, acidification, and water quality on Chesapeake region eelgrass
Abstract Although environmental requirements of seagrasses have been studied for years, reliable metrics for predicting their response to current or future conditions remain elusive.

Abstract Although environmental requirements of seagrasses have been studied for years, reliable metrics for predicting their response to current or future conditions remain elusive. Eelgrass ( Zostera marina L.) populations of the Chesapeake region lie near the southern limit of their range in the Western North Atlantic, exposing them to increasing thermal stress as the climate warms. However, CO 2 stimulated photosynthesis may offset some of the negative effects of temperature stress.
