Physiological Responses of Zostera marina and Cymodocea nodosa to Light-Limitation Stress

The effects of light-limitation stress were investigated in natural stands of the seagrasses Zostera marina and Cymodocea nodosa in Ria Formosa coastal lagoon, southern Portugal. Three levels of light attenuation were imposed for 3 weeks in two adjacent meadows (2-3 m depth), each dominated by one species. The response of photosynthesis to light was determined with oxygen electrodes. Chlorophyl...

Short-term growth and biomechanical responses of the temperate seagrass Cymodocea nodosa to CO2 enrichment

Seagrasses are often regarded as climate change ‘winners’ because they exhibit higher rates of photosynthesis, carbon fixation and growth when exposed to increasing levels of ocean acidification. However, questions remain whether such growth enhancement compromises the biomechanical properties of the plants, altering their vulnerability to structural damage and leaf loss. Here, we investigated ...

Growth and sediment space occupation by seagrass Cymodocea nodosa roots

The development, growth, and space occupation by the canopy and rhizosphere of a temperate Mediterranean seagrass meadow of Cymodocea nodosa, and the possible effects of meadow seasonal development on sediment redox conditions, were examined during the 1998 growth season. The meadow supported maximum biomass of leaves and rhizomes during July, and maximum root biomass in August. The meadow main...

Community metabolism and carbon budget along a gradient of seagrass (Cymodocea nodosa) colonization

We studied the effect of seagrass (Cymodocea nodosa) colonization on community metabolism and sediment conditions. The biomass of C. nodosa increased with time after seagrass colonization. The biomass increased steadily during the 6.1 yr of colonization to 9.1 mol C m22. Gross primary production increased from 7 to 49.3 mmol C m22 d21 during the first stages of the colonization and then decreas...
