計畫資料

| 計畫名稱 | Impact assesment in urban sand-clay coastal areas of Santa Cruz province, using methods of rapid assesment in changes of nematodes community structure. |

| 經費來源 | PICT AGENCIA-FONCYT 2/33345 (2005) |
| 研究區域描述 | 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. |
| 研究設計描述 | 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. |

取樣方法
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).
| 研究範圍 | 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. |
|---|---|
| 品質控管 | 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. |
方法步驟描述:
- 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.
