Demography and Biomass of the Seagrass Zostera marina in a Mexican Coastal Lagoon

Top-down and bottom-up stabilizing mechanisms in eelgrass meadows differentially affected by coastal upwelling

“…Percent organic matter (POM) content was calculated as overnight loss during ignition at 550°C. Total leaf length, width, and epiphyte biomass were estimated from 6 randomly selected vegetative shoots per sample, following procedures described by Poumian-Tapia & Ibarra-Obando (1999). Seagrass growth, measured in units of leaf length and mass, was determined from 3 randomly selected shoots within each sampling unit following standard methods (Short & Duarte 2002).…”

Benthic metabolism in San Quintin Bay, Baja California, Mexico

“…comm.). The most conspicuous benthic community in the system is the eelgrass (Zostera marina) (IbarraObando & Huerta-Tamayo 1987, Poumian-Tapia & Ibarra-Obando 1999. Ward et al (2003) assessed changes in major habitat coverage between 1987 and 2000.…”

“…Both systems are light-limited because of high turbidity and both have plankton as important primary producers (Lara-Lara & Alvarez-Borrego 1975, Cole 1989, Cabello-Pasini et al 2003. They also have prominent seagrass (Zostera marina) beds (Spratt 1989, Poumian-Tapia & Ibarra-Obando 1999 and a rather similar benthic fauna (Johnson 1970, SinicropeTalley et al 2000.…”

Dissolved inorganic nitrogen uptake kinetics and δ15N of Zostera marina L. (eelgrass) in a coastal lagoon with oyster aquaculture and upwelling influence

“…The eelgrass Zostera marina L. is the dominant submerged vegetation in coastal lagoons along the Pacific coast of the Baja California Peninsula like San Quintín Bay (Poumian-Tapia and Ibarra-Obando, 1999;Cabello-Pasini et al, 2003;Ward et al, 2003). In contrast to coastal lagoons at the southern end of the peninsula, eelgrass meadows at San Quintín Bay are exposed to human-induced and natural DIN inputs.…”
