Faunal list of biological indices based on benthic macroinvertebrates - Sélune Observatory
As part of the Sélune observatory, pilot stations have been set up along the main course of the Sélune, distributed from upstream to downstream of the hydroelectric dams. Three stations are located in the former reservoirs of the dams, while the other two, known as the reference stations, are outside the area of influence of the former dams (one downstream and the other upstream). At these stations, aquatic biocenoses (including benthic macroinvertebrates, biofilms, macrophytes, etc.) are monitored.
2 sampling campaigns (spring and autumn) for benthic macroinvertebrates (bmi) have been carried out since September 2014.
During each campaign, 2 sampling protocols are implemented:
- in accordance with standard NF T90-333, which enables the calculation of the IBG-DCE and I2M2 (‘SURBER’)
- via artificial substrates immersed for 1 month (‘SUBART’), in order to focus on measuring the ‘effect of dams’. The protocol is described in: Piscart C., Moreteau, J.C., Beisel J.N. (2006). Monitoring changes in freshwater macroinvertebrate communities along a salinity gradient using artificial substrates. Environmental Monitoring and Assessment 116: 529-542.
This layer details the benthic macroinvertebrate taxa and their abundance obtained after analysis (according to standard NF T90-388). These data are distributed by campaign and by sector. Taxa presenting all the morphological criteria clearly visible and characteristic allowing the exactitude of their determination and an irreproachable state of conservation are integrated into the reference collection of the Sélune Observatory. This collection can be consulted on request (see contact point).
Taxon determination is based on version v17 of the TAXREF reference.
The dataset is currently under embargo.
