Description

Tha aim of this database is collecting all the registered data of free-living marine Nematodes species from San Julian bay during January, 2009.

Data Records

The data in this occurrence 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 10,030 records.

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.

No Description available

Title Impact assesment in urban sand-clay coastal areas of Santa Cruz province, using methods of rapid assesment in changes of nematodes community structure.
Funding PICT AGENCIA-FONCYT 2/33345 (2005)
Study Area Description This project proposed to study for the first time the meiobenthos (Nematoda) with the aim to find the degree of disturbance in littoral sand-clay coastal areas of the Ría San Julián. The Ría San Julián has a complex variety of wild environments together with a urban human population that produces seawage and garbage, presently poorly treated. Coastal areas near San Julián city will be contrasted with natural areas of similar oceanographic characteristics.
Design Description This project proposed: a) To contribute to the biodiversity knowledge of meiobenthos (nematodes)on Santa Cruz province coasts. b) characterize using communitary structures of meiobenthos the degree of disturbance that the San Julian city coast presently has. c) To form two doctorate grant students in meiobenthos (Nematoda) related to impact assessment studies; e) To transfer and to teach about meiobenthos (Nematoda), which is not yet very well known in Argentina.

Sampling Methods

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).

Study Extent The study took place in three localities (mouth, city and El Rincón) and in three tidal levels (high, medium and low)on each locality, so nine sampling sites in total.
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 step description:

  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.
