Some reproductive parameters of populations of Macoma calcarea (Bivalvia, Tellinidae) in the Barents and Pechora Seas
Macoma calcarea is a boreal-arctic species widespread in all the northern seas of Russia. Like all bivalve molluscs M. calcarea plays an important role in marine ecosystems. Despite the widespread use many aspects of the biology of this species have not been adequately studied. The aim of the work i...
