Dear colleagues,

We are pleased to announce a new paper in the journal *Vestnik zoologii*,
Ukraine:

Linear transect surveys of abundance and density of cetaceans in the area
near the Dzharylgach Island in the north-western Black Sea.

Abstract: The first assessment of cetacean density and abundance by linear
transect survey was conducted in 2016 and 2017 in the shallowest coastal
area of the Ukrainian sector of the north-western Black Sea, in the
Dzharylgach Gulf and the northern Karkinit Gulf, total area up to 259 km2.
Three cetacean species were found present in the area in summer, and the
harbour porpoise was the most abundant species with the abundance of at
least a few hundred animals (estimated as 175 individuals in the
Dzharylgach Gulf), whereas the common dolphins (59) and bottlenose dolphins
(31) were present in lesser numbers. Common and bottlenose dolphins showed
the clearest patterns of habitat preferences, being restricted respectively
to the Dzharylgach and the northern Karkinit Gulf; an unusual trait is the
preference of the shallowest habitat by common dolphins. Recorded density
of harbour porpoises in the Dzharylgach Gulf is among the highest in the
whole Black Sea. Thus, the studied area may be an important summer habitat
for cetaceans.
