Abstract

Úrtak

Tvey sløg av feskvatns svampum, Racekiela ryderi (Potts, 1882) og Spongilla lacustris (Linne, 1758) eru skrásett í Føroyum, tað seinna skrásett fyri fyrstu ferð. Ein kjarni tikin í Skálafjørðinum hevði sporahylki við R. ryderi, sum eru frá umleið ár 8.600 áðrenn okkara tíð. Hetta er ein ábending um, at feskvatns soppar vóru millum tey fyrstu dýr at seta seg niður aftaná síðstu ístíð.

Abstract

Two species of freshwater-sponges, Racekiela ryderi (Potts, 1882) and Spongilla lacustris (Linne, 1758) are recorded from the Faroes, the latter as new to the islands. Gemmules of R. ryderi from a core in Skálafjørður have been dated to about 8600 years B.P., an indication that freshwater sponges were among the early immigrants after the last deglaciation.
