Abstract
Current systems in the World Ocean form fronts that divide water masses into frontal zones with different hydrological, physical, and chemical conditions. Water flows carry a variety of zooplankton organisms, creating for them both the necessary conditions for their existence and insurmountable barriers between neighboring water masses. We study zooplankton in the Drake Passage, a region of the Southern Ocean with a complex system of currents. Its waters are populated by eight common species of mesozooplankton. It turned out that seven of them inhabit both sides of the Polar Frontal Zone (PFZ), successfully overcoming the existing fronts. Individuals of these species do not differ significantly either morphologically or genetically on both sides of the front. However one species, Metridia lucens, stands apart from this list, as there are two genetically isolated but morphologically identical groups of this species on different sides of the PFR. Thus, genetic methods provide us opportunity to separate two populations of the one morphologically homogeneous species and to understand the mechanisms of separation of plankton species populations.
