ABSTRACT: Posidonia
oceanicameadows are experiencing a progressive decline, and monitoring their status is
crucial for the maintenance of theseecosystems.
We performed a comparativeanalysis of bed density, total phenol content
and protein expression pattern to assess the conservation status ofPosidoniaplants from the S. Marinella
(Rome, Italy) meadow. The total phenol content was inversely related to maximum
beddensity,
confirming the relationship betweenhigh phenol content and stressful
conditions. In addition,
protein expression pattern profilesshowed that the number of
differentially expressed proteins was dramatically reduced in the latest years
compared to previous analyses. Our results support the usefulness of
integrating solid descriptors, such as phenol content, with novel
biochemical/molecular approaches in the monitoring of meadows.
