Invasiviteit Niet invasief
Invasiviteit (toelichting) In the Netherlands this species with a restricted European distribution (North Sea, French Atlantic coast, Balthic, Mediterranean) is usually not considered an invasive species. Ates (2006) opposes arguments in (among others) Wolff (2005) and Nehring & Leuchs (1999), who consider D. cincta 'possibly an exotic species', probably imported into Atlantic Europe on the hull of ships or with oysters. In his paper (in Dutch with an English summary) Ates argues strongly against this and states non of the arguments used are valid. This view is followed by many Dutch (and English) authors, a.o. Leewis et al. (2005). Cohen & Carlton (1995) suggests the origin might possibly be the U.K. In spite of this the species is still often regarded as non-indigenous and invasive, even by Dutch authors (for instance Gittenberger 2009, Gittenberger et al. 2010). The ambiguity is still actual, especially lists and websites concerned with invasive species outside the Netherlands consider this species as non-native (for instance Katsanevakis et al. 2012, DAISIE and even WoRMS (acc. 22.06.2014)). The origin then is usually mentioned as cryptogenic, although sometimes 'Pacific' is mentioned (Gollasch & Nehring 2006). Shipping is usually mentioned as the species vector for dispersal.

  • Verspreiding in Nederland (toelichting) In contradiction to the assumptions of Nehring & Leuchs (1999) and Wolff (2005) based on which they presented Diadumene cincta Stephenson, 1925 as a non-indigenous species, Ates (2006) concludes that D. cincta has been a native species in Europe for a long time and probably also was present in Plymouth before the description by Stephenson in 1925. Several Dutch authors, among them Portielje (1933) knew the species from the Netherlands, but never considered it to be non-indigenous . The species is known from the province of Zeeland (common) and the Wadden Sea (local). It is also mentioned from along the North Sea coast of the provinces Noord- Holland en Zuid-Holland.
