Mytilaster minimus (Poli, 1795) (Mytilidae) is a small bivalve (maximum shell length = 20 mm) distributed on many hard bottoms of the intertidal zone in the Mediterranean and eastern Atlantic. The species has a planktonic larval stage, but larval morphology and life-span are unknown, so that its potential for dispersal cannot reliably be inferred. Individuals from brackish and marine waters are morphologically indistinguishable. The purpose of the present study was to investigate the genetic structure of M. minimus from the Orbetello Lagoon (Tuscany, Italy) and two adjacent marine sites.

Abstract
Mytilaster minimus (Poli, 1795) (Mytilidae) is a small bivalve (maximum shell length = 20 mm) distributed on many hard bottoms of the intertidal zone in the Mediterranean and eastern Atlantic. The species has a planktonic larval stage, but larval morphology and life-span are unknown, so that its potential for dispersal cannot reliably be inferred. Individuals from brackish and marine waters are morphologically indistinguishable. The purpose of the present study was to investigate the genetic structure of M. minimus from the Orbetello Lagoon (Tuscany, Italy) and two adjacent marine sites.File in questo prodotto:
