Abstract

Brown algae Chorda tomentosa Lyngb. 1819, representative of order Laminariales Mig. 1909, was found in the north-western part of the Black Sea (Ukraine, Odessa Bay, Cape Bolshoi Fontan) in spring 2015. This is a new invasive species in the Black Sea ecosystem and the only representative of brown laminarian algae. Ecological activity of this species is 82.2±4.3 m2·kg-1, that corresponds to the nutrient level of the area where it was found.

Keywords: Chorda tomentosa, alien (biological invasion, non-indigenous species), Black Sea, Ukraine
