“…Recent studies show that the level of expansion of the non-native Pectinatella magnifica is increasing not only in Europe and Asia, but also within the country of its native origin [ 2 , 4 , 5 , 8 , 20 ]. The AFLP technique is very popular in population and evolutionary genetic studies of organisms with no prior sequence knowledge, aiming to assess the degree of variability and genetic structure among tested individuals.…”

Background: Non-native species have aroused scientific interest because of their ability to successfully colonise areas to which they have been introduced, despite their sometimes limited genetic variation compared to their native range. These species establish themselves with the aid of some pre-existing features favouring them in the new environment. Pectinatella magnifica (Leidy, 1851), the freshwater magnificent bryozoan, is non-native in Europe and Asia. This study was designed to determine the genetic diversity and population structure of P. magnifica colonies collected from the Protected Landscape Area (PLA) and UNESCO Biosphere Reserve Třeboňsko (the Czech Republic) in the 2009 and 2011-2014 periods using Amplified Fragment Length Polymorphism (AFLP). Findings:The vast majority of the examined non-native colonies, except three colonies sampled in 2012, expressed very low levels of genetic variation, not differentiating from the USA native colony. The Bayesian clustering approach grouped the 28 accessions into two genetically different populations. Conclusions:The data suggest relatively low gene diversity within all colonies, which might reflect the recent expansion of P. magnifica in the Czech Republic.

“…The temperature limitation for the growth and reproduction could be the possible explanation why the colonies occurred only at 3.5 km of the coastline in the semiisolated Vuoksi-Virta and the species was not observed in the most part of the 150km riverbed of Vuoksi. Phylactolaemates in the Ukrainian part of the Danube River delta start to form new colonies at the beginning of the summer, and the destruction of the colonies begins in the second decade of October-November (Aleksandrov et al, 2014). In the Leningrad oblast, the duration of the colony life of C. mucedo is about the same (K. Shunkina, personal communication).…”

First record of the freshwater bryozoan Pectinatella magnifica in north-west Russia with a description of sensory structures

Colonies of the freshwater bryozoan Pectinatella magnifica (Leidy, 1851) were found in north-west Russia for the first time. As the colonies have been observed in Vuoksi river connecting Saimaa and Ladoga lakes, most likely this is a result of the downstream migration from Finland. Details of the general morphology of P. magnifica and distribution of sensory structures on the lophophore and colony surface were studied using scanning electron microscopy. Three types of sensory structures were recorded. Two rows of presumably immobile cilia were found on the latero-frontal surfaces of tentacles, and this type is common in Bryozoa. One-two sensory cilia with bases surrounded by short microvilli were detected on the abfrontal surface of the tentacles as well as on the outer and inner surfaces of the lophophoral arms. The mechanosensory function of both these types was assumed like in other bryozoans. Sensory structures of the third type were microvillous 'knobs' situated on the colonial body wall surface. They were described for the first time in Bryozoa. Their possible photosensory function is discussed.

The first records from outside the United States were in 1883 in Germany near Hamburg (Kraepelin 1887;Zoric et al 2015), since when it has spread into many other European countries, including Poland (Kaminski 1984), France (d'Hondt and Condé 1996), the Netherlands (Leuven et al 2009), Austria (Bauer et al 2010), Hungary (Balounová et al 2011;Szekeres et al 2013), Czech Republic (Balounová et al 2011;Pazourek et al 2016), Luxemburg (Massard et al 2013) and Ukraine (Aleksandrov et al 2014). The species spread seems to have accelerated during recent decades (e.g.…”

Introduced alien species bring potential adverse impacts on biodiversity and ecosystem functions. International shipping is an important vector for such unintentional introductions in aquatic environments. Therefore, in addition to climate change and eutrophication, increasing international shipping may enhance the spread of alien species into areas which have not previously been considered prone to alien invasions. One example of such development might be the recent invasion of the moss animal Pectinatella magnifica into Finnish inland waters, which are generally considered to be hostile to alien species. We took advantage of observations made by the general public and recorded by environmental authorities to describe the invasion history of the species in Finland. The records of P. magnifica were almost exclusively from the Vuoksi watercourse, where the species was most likely introduced by international shipping ca 10-15 years ago. The species occurred mainly in the vicinity of ports of international shipping, but was also abundant in an area with only domestic cargo transport. Only one confirmed observation in Lake Kirkkojärvi was from outside the Vuoksi watercourse. Most colonies were found attached to landing stages or submerged, relatively rigid water plants, and the species seemed to avoid less rigid water plants, such as water lilies. Once established, the species may spread by vectors such as recreational boating or water birds and fish. The species poses some risks to the ecosystem, including a risk to farmed and wild salmonid fish by serving as a potential host for the myxozoan endoparasite Tetracapsuloides bryosalmonae, the causative agent for proliferative kidney disease (PKD), known to be detrimental for salmonid fish.
