Solitary ascidians (Tunicata, Ascidiacea and Sorberacea) of the Faroes: Stakir sjóbjølgar (Tunicata, Ascidiacea og Sorberacea) við Føroyar

Abstract

Úrtak

Allir teir støku sjóbjølgarnir, sum vóru innsavnaðir undir BIOFAR-verkætlanini eru rannsakaðir og navngreindir til lægstu møguligu flokkingarskipan. Innan BIOFAR verkætlanin byrjaði í 1987, vóru 24 sløg av stakum sjóbjølg um staðfest innan fyri 200 fjórðinga sjómarkið. Eftir BIOFAR er talið økt til 36. Stakir sjóbjølgar eru staðfestir í 17 prosent av støðunum (225 av tilsamans
1325). Tólv eru staðfestir fyri fyrstu ferð: Ascidia mentula Müller, 1776, Styela atlantica (Van Name, 1912), Styela similis Monniot, 1970, Styela theeli Ärnbäck-Christie-Linde, 1921, Cnemidocarpa mollispina Ärnbäck-Christie-Linde, 1922, Cnemi do carpa
mortenseni Hartmeyer, 1912, Polycarpa porculus Monniot C. and Monniot F., 1979, Molgula herdmani Bjerkan, 1905, Molgula mira (Ärnbäck, 1931), Molgula occulta Kuppfer, 1875, Eugyra islandica Millar, 1974, og Asajirus arcticus (Hartmeyer, 1923). Slektirnar Cnemidocarpa og Asajirus eru staðfestar fyri fyrstu ferð á økinum.

Abstract

All the solitary ascidian material collected during the BIOFAR programme has been worked through and identified to lowest possibly taxomomic level. Before the BIOFAR programme star ted in 1987, twenty four solitary ascidian species had been recorded within the Faroese Exclusive Eco nomic Zone (EEZ). The BIOFAR sampling has in creased this number to thirty six. Solitary ascidians are recorded at 17% of the stations (225 out of 1325). Twelve species were recorded for the first time:
Ascidia mentula Müller, 1776; Styela atlantica (Van Name, 1912); Styela similis Monniot, 1970; Styela theeli Ärnbäck-Christie-Linde, 1921; Cnemidocarpa mollispina Ärnbäck-Christie-Linde, 1922; Cnemidocarpa mortenseni Hartmeyer, 1912; Polycarpa porculus Monniot C. and Monniot F., 1979; Molgula herdmani Bjerkan, 1905; Molgula mira (Ärnbäck, 1931); Molgula
occulta Kuppfer, 1875; Eugyra islandica Millar, 1974; and Asajirus arcticus (Hartmeyer, 1923). Two genera, Cnemidocarpa and Asajirus, are recorded for the first time in the area.
