| The primary production and the respiration of Zostera noltii beds in the Thau lagoon were studied by means of the benthic bell jar technique, Concurrently, environmental data (temperature, light and nutrients) as well as morphological data of seagrass meadows (leaf width and height, density of shoots, above/below-ground biomass ratio) were collected with the purpose of explaining most of the observed variations in metabolism, Seagrass plus epiphyte respiration rates were influenced mainly by the water temperature, showing a typical exponential response to an increase in temperature, Surprisingly, measurements of production rates were not related to incoming light intensities recorded at the seagrass canopy level, An equation frequently used for terrestrial... |
