“…D. antarctica showed much lower levels of arsenic, and this is The lowest level of arsenic in the present study was detected in the seagrass P. oceanica, which is also consistent with the values reported in the literature, such as 5 mg kg −1 (Grauby et al 1991) or the range 14-21 mg kg −1 reported by Gosselin et al (2006) for this seagrass collected in the west Mediterranean zone.…”

Occurrence of arsenic species in the seagrass Posidonia oceanica and in the marine algae Lessonia nigrescens and Durvillaea antarctica

The seagrass Posidonia oceanica from the Mediterranean coast and the brown algae Durvillaea antarctica and Lessonia nigrescens from the Chilean coast were analysed for total arsenic and for arsenic species. Arsenic species were extracted with water and measured by high-performance liquid chromatography-inductive coupled plasma mass spectrometry. Arsenite, arsenate, methylarsonate, dimethylarsinate, sulfonate sugar, sulphate sugar and phosphate sugar were analysed with an anion exchange column. Arsenobetaine, arsenocholine and glycerol sugar were separated with a cation exchange column. An extract of Fucus serratus was used to assign the arsenosugar peaks in the chromatograms from the sample extracts. In addition to the four common arsenosugars found in algae, inorganic arsenic was also measured in some samples, with the highest content found in L. nigrescens. The certified reference material (CRM) NIES no. 9 Sargassum fullvellum was analysed for quality assessment of total arsenic, and moreover, arsenosugars were also determined in this CRM.

“…This plant has been widely used to provide important information on the vitality and dynamics of seagrass systems, and to assess human impacts on the environment (Boudouresque et al 2006;Romero et al 2007). Furthermore, P. oceanica has been used as a bioindicator for metals for the last three decades (Panayotidis et al 1990;Costantini et al 1991;Grauby et al 1991;Taramelli et al 1991;Paterno et al 1991;Carlotti et al 1992;Pergent-Martini et al 1993;Augier et al 1994;Catsiki et al 1994;Malea et al 1994;Bougerol et al 1995;Duarte et al 1995;Ledent et al 1995;Romeo et al 1995;Warnau et al 1996;Pergent and Pergent-Martini 1999;Sanchiz et al2001;Campanella et al 2001;Baroli et al 2001;Ancora et al 2004 ;Kljakovic-Gaspic et al 2004;Tranchina et al 2005;Maserti et al 2005;Gosselin et al 2006;Fourqurean et al 2007;Lafabrie et al 2009;Lopez y Royo et al 2009;Cozza et al 2013;Conti et al 2014;Richir and Gobert 2014) given its capability to accumulate metals such as copper, lead, cadmium, nickel, zinc.…”

The accumulation of the five trace metals (TMs) cadmium, copper, lead, nickel and zinc was measured in Posidonia oceanica leaves. Shoots were seasonally sampled at 8-10-m depth from four stations located in Port El Kantaoui area, Tunisia, during four campaigns performed in 2012. Levels of the five TMs were analyzed using inductively coupled plasma atomic emission spectrometry (ICP-AES) in three compartments of P. oceanica shoots: blades and sheaths of adult leaves and intermediate leaves. Results showed a preferential accumulation of Cd, Pb, Ni and Zn in adult leaf blades. Therefore, we focus on the study of this compartment. TM levels of blades of adult leaves decreased in the following order: Zn > Ni > Cu > Pb > Cd, irrespective of the season. Levels of the five TMs significantly differed between seasons (p < 0.01). Levels of Cd and Cu showed a seasonal pattern: Cd decreased from spring to winter while Cu increased during that same period of time. A significant correlation (p < 0.01) was found between Cd-Cu and Cd-Pb. A significant correlation (p < 0.05) was also noted between Cd-Ni in the adult leaf blades. A relationship was recorded between the foliar surface of the adult leaf blades and Zn accumulation. This survey allowed to highlight the annual variation of TM accumulation in adult leaf blades of P. oceanica, in relation with ecophysiology of this seagrass. Therefore, this study reinforces the usefulness and the relevance of this compartment of P. oceanica, easy to sample without destruction of whole shoot, as a bioindicator of Zn, Ni, Cd and Pb contamination.

“…Seagrass beds are among the most important benthic communities in temperate coastal areas, where they have a fundamental ecological role (Kuo et al, 1996;Cambridge and Hocking, 1997). Seagrass is known to be an indicator and integrator of environmental variations, and not only as one simple taxon (Grauby et al, 1991;Pergent, 1991). The highlighting of such variations supposes a sufficient lapse of time so that a phenomenon can be perceived and a regular follow-up made to assess cyclic direct relations between environmental phenomena and benthic populations.…”

Temporal and spatial changes of seagrass meadows in a Mediterranean coastal lagoon

2002

Aerial photographs and in situ data of the Urbinu Lagoon (one of the largest and deepest ponds in Corsica, Mediterranean Sea) permit the establishment of a cartography of its aquatic benthic assemblages and types of sea-beds. It was possible to distinguish in the photographs submerged structures such as: sand, pebbles, mud and seagrass meadows. Seagrass beds were the predominant vegetation type in this lagoon (comprising 14-29% of the total area depending on the year studied), and their distribution was incorporated into a geographical information database, and then compared with historical data. Temporal and spatial change in seagrass meadows was assessed between 1990 and 1997. Change in total extent was evaluated through a map to map comparison of data interpreted from image processing using colored aerial photographs (1990, 1994 and 1997). The overall net change was a 12% decrease between 1990 and 1994 and a 16% increase between 1994 and 1997. These observations imply that regressions are not irreversible over the past 7 years, and show that seagrass meadows in this area have been stable despite environmental perturbations, since the lost zones were recolonized.
