Descriptions:
Free-living nematodes of the Mar Piccolo of Taranto (Ionian Sea, southern Italy), 2013-2014 in the framework of the Italian flagship project RITMARE. In June 2013 and April 2014, sampling was carried out at four sites by scuba divers who collected five virtually undisturbed sediment cores using polycarbonate sample tubes (12.7 cm I.D. with a sample area of 127 cm2). In laboratory, one sediment core was subsampled by means of 3 cut-off plastic syringes (2.7 cm I.D., surface area of 5.72 cm2, 0-10 cm top sediment) in order to obtain three pseudoreplicates. The nematodes (38–1000 m) were extracted from sediment subsamples by sieving each pseudoreplicate and by centrifuging the material retained by a 38 μm mesh net with Ludox HS-40 (density of 1.15–1.18 g cm−3). For each pseudoreplicate, 100 nematodes were randomly picked out using a fine pin under a stereomicroscope (Zeiss Discovery V20, magnification 40×), transferred from formalin to glycerol through a series of ethanol-glycerol solutions and finally mounted on permanent glass slides in anhydrous glycerin. Nematodes were identified under a microscope (100x magnification) at the genus level using dedicated pictorial and identification keys.
