Description

The aim of this database is collecting all the registered data of free-living marine Nematodes species from San Antonio and Camarones sandy beaches during March 2006.

Sampling Description

Study Extent

The study took place in two localities (San Antonio and Cormoranes beaches) and in three tidal levels (high, medium and low) on each locality, so six sampling sites in total.

Sampling

Marine nematodes were extracted from samples using the elutriation/decantation LUDOX TM (colloidal silica polymer) method at a specific gravity of 1.15, quantifying only organisms that pass through a 500 um and are then retained by a 63 um mesh. Samples were evaporated to anhydrous glycerol and permanent slides made (Somerfield & Warwick 1996). The classification followed for the systematic position of the meiofauna taxa was Hulings and Gray (1988).

Quality Control

All data were gathered from the primary information source (Nematode collection CENPAT, CNP-NEM). The identification are supported by the technical report and by the scientific papers associated with the project.

Method steps

  1. Taxonomic identifications of Nematoda were obtained using light microscope (Zeiss Photomicroscope or Olympus BX51 equipped with differential Interference Contrast) and/or photographed by a digital camera (NIKON D80 with adapted software). The specimens are deposited in Centro Nacional Patagónico (CENPAT-CONICET), Chubut, Argentina.

Taxonomic Coverages

This data base covers the two clases of free-living marine nematodes: Enoplea and Chromadorea. All nematodes has been identified to genera or species.
  1. Animalia
    rank: kingdom
  2. Nematoda
    common name: Nematodos rank: phylum
  3. Enoplea, Chromadorea
    rank: class

Geographic Coverages

This sampling of San Antonio and Cormoranes beaches, 2006, was at three different tidal levels in each locality, six different sites in total.
