The non-native freshwater magnificent bryozoan Pectinatella magnifica
(Leidy, 1851) was firstly recorded in the summer of 2011 from the Danube
River (side arm Rackevei-Soroksari Duna downstream from Budapest).
Despite intensive research along the length of the Danube River between
Budapest and Belgrade in 2001-2013, it has not been detected to expand
its range. Recently, the species has distributed rapidly in the
900-km-long downstream stretch of the Danube River. The species was
found at ten sites, between river kilometres 1586 (Hungary, downstream
from Budapest) and 685 (the Romanian-Bulgarian stretch of the Danube
River). The highest colony abundance was recorded from the Iron Gate
(Derdap) sector that is influenced by the backwater effect of the Iron
Gate dams. Our findings reveal the capacity of this bryozoan to spread
extremely rapidly and to invade successfully stretches of rivers that
are exposed to hydromorphological pressures.
