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.

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 4,837 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.

Title Biodiversity meiofauna communities in sandy-silty beaches in the provinces of Río Negro and Chubut (“Biodiversidad de comunidades meiofaunísticas en playas areno-limosas de las provincias de Río Negro y Chubut” )
Funding Proyecto PNUD ARG 02/018 Subproyecto AB55 (2006-2007).
Study Area Description The project objectives were to perform first time in Argentina, an inventory of marine meiofauna taxa coastal in urban and natural beaches. Studying them, using multivariate methods and studying how these relate to environmental variables. Trying to observe the biogeographic patterns from 40 ° 43 'Lat S (Río Negro province) to 45 ° 59' Lat S (Chubut province).
Design Description This project proposed: a) To contribute to the biodiversity knowledge of meiobenthos (nematodes) on Rio Negro and Chubut province coasts. b) Characterize using communitarian structures of meiobenthos the degree of disturbance that the San Antonio city coast and Cormoranes beach natural 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 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.
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.
