OlOFAR-vcrkætlanini eru rannsakaðirog navngreindir

Eftir BIOFAR er talið økt til 36. Stakir sjóbjølgar eru

Abstract
the solitary ascidian material collected during the
tOFAR programme has bcen workcd through and
'dentified to lowest possibly taxomomic level. Before
'he BIOFAR programme started in 1987, twenty four
V'litary ascidian spccics had bcen recorded within the
aroese Exclusive Economic Zone (EEZ). The BIOFAR
Sa,iiplinghas increased thisnumberto thirty six. Solitary
ascidians are recorded at 17% of the stations (225 out
°f 1325).
Twelve species were recorded for the first time:
Ascidia mentula Miiller, 1776; Styela atlantica (Van
Name, 1912); Styela similis Monniot, 1970; Styela theeli
Árnbáck-Christie-Linde, 1921; Cnemidocarpa molli-
spina Árnbáck-Christie-Linde, 1922; Cnemidocarpa
mortenseni Hartmeyer, 1912; Polycarpa porculus
Monniot C. and Monniot F., 1979; Molgula herdmani
Bjerkan, 1905; Molgula mira (Árnbáck, 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.
Introduction
Previous investigations on Faroese
ascidians
The first species list with Faroese fauna was
made by Svabo 1781 and 1782 (Svabo,
1959). At that time, the ascidians were
placed within Mollusca. Although the mol-
luscs are fairly well represented in the list,
no ascidians were included. The earliest
source on ascidians from the Faroes is the
collections of the Zoological Museum of
Copenhagen: a specimen of Molgula com-
planata (Alderand Hancock, 1870), identi-
