Distribution of Invasive Red Alga Womersleyella setacea (Hollenberg) R.E. Norris (Rhodophyta, Ceramiales) in the Adriatic Sea

Womersleyella setacea (Hollenberg) R.E. Norris (Rhodophyta, Ceramiales) is an invasive macrophyte in the Mediterranean Sea, first recorded in the coast of Italy in 1986. Here is a review of the geographic and depth limits of W. setacea invasion in the Adriatic Sea since its first record in 1997 in the northern Adriatic. Algal turfs were collected and examined from different locations in the Croatian part of the Adriatic Sea from 2005 to 2009 by SCUBA diving and grab sampling. A total of 50 sites invaded by W. setacea were recorded in the Adriatic Sea, 40 new sites in this research and 10 from the literature records. Womersleyella setacea was recorded from seven to 72 meters of depth. Only sterile specimens without any reproductive structures were found. The magnitude of the invasion is discussed.
