Espèces marines du genre Mastogloia de la zone infralittorale à l'Ile de Groix

Marine Mastogloia species from the sublittoral zone at the Groix Island

°°°°°°°°°°°°°°°°°°
Site A:  " Les Sables rouges" (3° 25' 02.1" W, 47° 37' 39.3" N). 1.5-2 m depth (charted depths).
Site B:  "Saint Nicolas" (3° 29' 11.0 W,  47° 37'55.6 N). 1.5-4.5 m depth.
Site C: "Edouard de Cougy" (3° 24' 10.0 W, 47° 37' 53.4 N). 6-7 m depth.

Most of the observed Mastogloia taxa were very rare in the samples. Between 8 and 12 slides were carefully scanned for each set of samples collected every summer on the sites A and B, and during the period 2004-2006 on the site C. So, no quantitative study was performed and the numbers of frustules/valves just provide an indication of the relative presence  of the various observed taxa.
The undetermined taxa identified by a number were described in Loir & Novarino, 2013. Those identified by a letter were already found in the Mediterranean Sea (this website).
