Description
Monitoring of free-living nematodes at the C1-LTER station (Gulf of Trieste, Northern Adriatic Sea), seasonal frequency from 07-2010 to 07-2012. The sampling was carried out by a KC Haps bottom corer with 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 mm) 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, 100-120 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.
Data Records
The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 31 records.
2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
