Tab. 1 - Sample size (N), density (D), minimum, maximum and mean (with standard deviation) total
shell length (Lt) of recorded specimens along transects RI (Isolotto Rosso island) and MI
(Molara island).
Numero (N), densità (D), lunghezza totale (L t) minima, massima e media (con deviazione
standard) dei bivalvi individuati nei due transetti RI (Isolotto Rosso) e MI (Isola di Molara).
Transect N D (ind/m 2 ) Lt min (cm) Lt max (cm) Lt mean + st. dev. (cm)
RI 11 0,02 8,70 47,33 19,23 + 11,37
MI 18 0,04 8,86 50,14 31,32 + 15,60
Statistically significant differences in number and in total shell length of P. nobilis
specimens along the surveyed transects were shown by the performed unpaired T-test
(T=-3,36, df=27, P=0,010 and T=2,23, df=27, P=0,034 respectively).
Conclusions – The presence of juveniles - specimens with a total shell length
