Eastern Mediterranean Syllidae from three locations in Crete and Israel

Description in English

Specimens from Israel were collected on 31.5.2009 and 11.10.2009 in Haifa Bay, (Israel, Eastern Mediterranean Sea) from soft sediments of mixed grain sizes in shallow waters. Sediment samples were taken with a Van-Veen grab (KAHLSICO, model WA265/SS214) 32x35cm, volume 20 l, penetration 20 cm. The sediment was preserved in buffered formalin 10% for 3-7 days, then sieved through a 250 µm mesh sieve and subsequently stored in 70% ethanol. Specimens from Crete were collected in September 2007 and June 2008 from two sites in northern Crete characterized by a continuous hard bottom habitat with dense algal coverage and a moderate wave exposure. At each site, two vertical transects with sampling depths at 1 m, 5 m, 10 m, 15 m and 20 m were defined and five replicates were taken from each transect and depth. Samples were collected by means of SCUBA diving according to the NaGISA protocol (Iken and Konar 2003). A plexiglas frame (25 x 25 cm) with a net of 0.5 mm mesh size attached to its top opening was placed onto the rock and the surface within the frame was scraped off. The sample was collected by a manually operated suction device, supplied by air from an extra scuba tank. Large particles (>2 cm) were collected manually after suction. The samples were subsequently washed through a 0.5 mm mesh sieve, fixed and preserved in 99% ethanol. Specimens were examined under an Olympus SZx12 stereomicroscope and an Olympus BX50 microscope and identified by employing the most recent literature on Syllidae (e.g. Nygren 2004, San Martín 2003, 2005, San Martín and Hutchings 2006). The syllid records from the NaGISA project are also contained in the full dataset "Polychaetes from two subtidal rocky shores of the North coast of Crete, collected for the NaGISA project 2007-2008."

Abstract in English

This is a combined dataset on Syllidae (Annelida, Polychaeta) originated from two projects: NaGISA (Natural Geography in Shore Areas, a long term monitoring project following a global protocol) and a study on the Benthos of Haifa Bay.
