Biological features and intraspecific variation of three-spine stickleback Gasterosteus aculeatus (Linnaeus, 1758), the Kola Peninsula
The biological characteristics and intraspecific variability of threespine stickleback, Gasterosteus аculeatus, from the estuary of the River Tuloma and lakes Venzin and Kulonga on the Kola Peninsula have been studied. Four morphotypes of threespine stickleback (trachurus with a keel, semiarmatus wi...
