Evaluation of Relationships Between Cover Estimates and Biomass in Subtropical Seagrass Meadows and Application to Landscape Estimates of Carbon Storage

description | Seagrass habitats provide invaluable ecosystem services, including the ability to sequester carbon through primary production. In the absence of significant grazing pressure, changes in seagrass biomass reflect net photosynthetic activity in response to the light environment. We developed linear models to convert a commonly measured parameter, percent cover, into above- and belowground biomass for three tropical seagrass species, Thalassia testudinum, Halodule wrightii and Syringodium filiforme. Linear models were estimated from the analysis of 126 biomass cores collected at five levels of percent cover from three coastal bays in Texas. The models showed an increase in aboveground biomass with increased percent cover (R² = 0.52–0.77), but belowground biomass displayed greater variability with respect to percent cover (R² = 0.15–0.63). Such linear biomass models can provide valuable estimates of carbon storage potential in living seagrass tissues using monitoring data collected across large spatial scales within the Gulf of Mexico.
Los hábitats de hierba marina proporcionan servicios inestimables de los ecosistemas, incluyendo la capacidad de secuestrar el carbono a través de la producción primaria. En ausencia de una presión de pastoreo significativa, los cambios en la biomasa de los pastos marinos reflejan la actividad fotosintética neta en respuesta a la luz ambiental. Se desarrollaron modelos lineales para convertir un parámetro comúnmente medido, por ciento de cobertura, en biomasa subterránea y subterránea para tres especies de pasto marino tropical, Thalassia testudinum, Halodule wrightii y Syringodium filiforme. Los modelos lineales se estimaron a partir del análisis de 126 núcleos de biomasa recolectados en cinco niveles de cobertura porcentual de tres bahías costeras en Texas. Los modelos mostraron un aumento de la biomasa aérea con mayor cobertura porcentual (R² = 0,52–0,77), pero la biomasa subterránea mostró mayor variabilidad con respecto al porcentaje de cobertura (R² = 0,15–0,63). Tales modelos de biomasa lineal pueden proporcionar valiosas estimaciones del potencial de almacenamiento de carbono en los tejidos vivos de los pastos marinos usando datos de monitoreo recolectados a través de grandes escalas espaciales dentro del Golfo de México. |
