"What we captured in 2001 was the loss of those mussels and implications for an entire ecosystem," said Brown University ecologist Andrew Altieri, who with biology professor Jon Witman wrote the study published in the March issue of Ecology.

Within days, a hypoxic episode triggered by warm weather, low wind and the usual nutrients contributed to fish kills and beach closures around the bay.
