Biomass estimates of Pacific herring, Clupea pallasi, in California from the 1990-91 spawning-ground surveys [PDF]
, 1991 The spawning biomass of Pacific herring, Clupea pallasi, estimated from spawning-ground surveys in San Francisco Bay declined to 45,850 tons this season, following a peak of 71,000 tons in the 1989-90 season. This is the first major decline since the

Genetic distance predicts trait differentiation at the subpopulation but not the individual level in eelgrass, Zostera marina. [PDF]
, 2018 Ecological studies often assume that genetically similar individuals will be more similar in phenotypic traits, such that genetic diversity can serve as a proxy for trait diversity.

Nitrogen Cycling in Widgeongrass and Eelgrass Beds in the Lower Chesapeake Bay
NitrogenEelgrass (Zostera marina) loss occurs worldwide due to increasing water temperatures and decreasing water quality. In the U.S., widgeongrass (Ruppia maritima), a more heat-tolerant seagrass species, is replacing eelgrass in certain areas.
