“…This result is similar to that reported by Catsiki and Panayotidis (1993) for copper and nickel residues in leaves, roots and rhizomes of P. oceanica and Cymodocea nodosa collected from Greek coastal areas and for five trace metals and five seagrass species collected from Australian coastal waters (Prange and Dennison, 2000).…”

“…The contribution of toxic chemicals to seagrass declines, the focus of this study, is largely unknown and has been investigated less frequently than the effects attributable to nutrient enrichment which is considered the primary cause of seagrass declines. However, some consider the impact of anthropogenic chemicals to be significant and worthy of increased investigation (Catsiki and Panayotidis, 1993;Short and Wyllie-Echeverria, 1996;Peters et al, 1997;SchlacherHoenlinger and Schlacher, 1998;Bester, 2000;Ralph, 2000).…”

“…This paper summarizes the results of the survey and compares them to those previously reported for other grass beds and geographical areas. The results serve as a baseline database to which future evaluations can be compared, represent realistic exposure concentrations which will be useful for future phytotoxicity tests, and add to the ongoing evaluation of the suitability of seagrasses to serve as indicators of environmental condition (Brix et al, 1983;Ward et al, 1986;Tiller et al, 1989;Catsiki and Panayotidis, 1993;Pergent-Martini, 1998;Prange and Dennison, 2000).…”

Some anthropogenic contaminants were prevalent in seagrass and their rooted sediments but the biological significance is unknown. AbstractContaminant concentrations were determined for media associated with 13 Florida seagrass beds. Concentrations of 10 trace metals were more commonly detected in surface water, sediment and two seagrass species than PAHs, pesticides and PCBs. Concentrations of copper and arsenic in surface water exceeded Florida aquatic life criteria more frequently than other trace elements. Total organic carbon, mercury, chromium, zinc, total chlordane, total PAHs, total PCBs, DDD and DDE were significantly greater in seagrass-rooted sediments than adjacent non-vegetated sediments. Total DDT, DDD, DDE, total chlordane, arsenic, copper and nickel exceeded proposed sediment quality guidelines at six of 13 grass beds. Pesticides, PAHs, and PCBs were below detection in seagrass tissues. Mercury, cadmium, nickel, lead and silver were detected in 50% or more of the tissues for Thalassia testudinum (turtle grass) and Halodule wrightii (shoal grass). Spatial, interspecific and tissue differences were usually an order of magnitude or less.

“…Our concentrations of Cd and Pb are much lower than those found for the impacted site of Antikyra Gulf in Greece [29], whereas the concentrations of Cr were lower than those found in an impacted site of the Aegean Sea [30]. The comparison of the concentration of trace metals in Posidonia tissue revealed significant differences among June and November for all the investigated variables.…”

Ecological Assessment of a Marine Coastal Area Affected by a Power Plant Water Discharge (Brindisi, Adriatic Sea)

Coastal ecosystems are subjected to multiple stresses, from physical disturbance to chemical contamination related to the local anthropogenic activities. The recent European directives and Italian laws recommend that the assessment of the ecological quality of costal seawater should be based on an integrated approach, taking into account the ecological complexity of the systems and highlighting the potential sources of impact. Here, we present the results of an environmental study carried out in the marine coastal area affected by the sea discharge of a Combined Cycle Power Plant (Torre Cavallo, Brindisi) and characterized by the presence of a Posidonia oceanica meadow. The study focused on the concentration of chemical contaminants in sediments, coupled with the study of quali-quantitative determinations of biological benthic communities meio-and macrozoobenthos). Data were integrated with data of phenology and lepidochronology of P. oceanica, as well as the concentrations of trace elements in leaves and rhizomes, in order to identify potential sources of stress. Results suggested a good status of health of the coastal marine ecosystem.

“…Heavy metals are taken up by seagrasses and accumulate in different tissues to different extents [81][82][83]. Several seagrass species such as Posidonia oceanica [84], Cymodocea nodosa [85], Cymodocea spp., Enhalus acoroides, Halodule spp., Halophila spp., Syringodium isoetifolium, and Thalassia hemprichii [83,86,87] have been even used as bioindicator for heavy metal accumulation in contaminated and noncontaminated areas.…”

Highlights in Seagrasses’ Phylogeny, Physiology, and Metabolism: What Makes Them Special?

The marine seagrasses form an ecological and therefore paraphyletic group of marine hydrophilus angiosperms which evolved three to four times from land plants towards an aquatic and marine existence. Their taxonomy is not yet solved on the species level and below due to their reduced morphology. So far also molecular data did not completely solve the phylogenetic relationships. Thus, this group challenges a new definition for what a species is. Also their physiology is not well understood due to difficult experimental in situ and in vitro conditions. There remain several open questions concerning how seagrasses adapted secondarily to the marine environment. Here probably exciting adaptation solutions will be detected. Physiological adaptations seem to be more important than morphological ones. Seagrasses contain several compounds in their secondary metabolism in which they differ from terrestrial plants and also not known from other taxonomic groups. Some of these compounds might be of interest for commercial purposes. Therefore their metabolite contents constitute another treasure of the ocean. This paper gives an introduction into some of the most interesting aspects from phylogenetical, physiological, and metabolic points of view.
