Genetic diversity and structure in two protected Posidonia oceanica meadows

Ecological Function of Phenolic Compounds from Mediterranean Fucoid Algae and Seagrasses: An Overview on the Genus Cystoseira sensu lato and Posidonia oceanica (L.) Delile

“…A high quantity of polyphenols was found at Santa Marinella, where P. oceanica was ranked as a disturbed one. This low ranking was confirmed by the mean phenol content, quite high and scattered, and the low genetic variability, with a very high similarity of specimens at a local scale [132,140].…”

“…Even if additional researches are necessary to define thresholds for classifying the different level of perturbation, the obtained results open interesting perspectives on the application of the phenol content in Cystoseira sensu latu and P. oceanica as possible biomarkers of environmental quality. In monitoring surveys, the assessment of health marine ecosystems should make provision for multidisciplinary investigations [161,162] and multiparametric approaches, including physiological biomarkers, biomarkers of general stress and more specific biomarkers [131], but also molecular ones [16,27,140,163].…”

“…Since the changes in phenolic compounds represent a response to environmental stressors, they can be used to screen the P. oceanica health status during the regular monitoring programs carried out for management purposes [16,17,113,116,132,139,140]. Two promising tools (easy, rapid and inexpensive): phenolic compounds in rhizome and Random Amplified Polymorphic DNA (RAPD) markers in leaves, were recently proposed to monitor the health state of P. oceanica meadows [17,116,132].…”

A Benthic Zonation System as a Fundamental Tool for Natural Capital Assessment in a Marine Environment: A Case Study in the Northern Tyrrhenian Sea, Italy

“…The estimate of long-term sequestered carbon through the metabolic and ecological processes in P. oceanica is 10-25% of total production [37]. To estimate the value of this benefit, phenological laboratory analyses [14,38], for the P. oceanica meadows, in the study area, are used to assess the biomass production. Using this approach, the carbon sequestered in the short term (10%) was determined as 0.3 tons/ha, and that in the long term (25%) was 0.7 tons/ha.…”

“…Using the available data for the P. oceanica meadows for the study area [14,15,38,42], it was possible to assess the economic value of O 2 production, using the cost of industrial methods of making oxygen [46]. The cost of the industrial production of 1 kg of O 2 was 0.05 €, and the total O 2 production from P. oceanica, in the study area, was about 10143 Kg/ha/yr.…”
