Occurrence

Specimen

This dataset comprises the occurrences associated to the riverine invertebrate specimens collected from pool mesohabitat of slightly altered rivers of Sardinia Island, the second biggest island of the Mediterranean Sea. Each row in the dataset corresponds to a single vial related to a single sampling event (site and date) and to a specific sampling unit. The single vial contains one or more individuals of the same taxon. A catalogue number consisting of the collection code (SARDNP) and a progressive six digit number is assigned to each row. The final digit can be a letter if pictures of the preserved specimens are taken. This dataset is provided within the Activity WP6.6, "National Network of Aquatic Science Collections," of the ITINERIS project - Italian Integrated Environmental Research Infrastructures System - CUP B53C22002150006.

Study Extent: Data included in the present dataset were collected, following the aims of MICARI and INHABIT projects.
Sampling: The riverine benthic invertebrates were sampled adopting the proportional and quantitative multi-habitat approach (the protocol specified in the column samplingProtocol of the dataset), which is the Italian standard for the monitoring of wadable water bodies under the WFD (CNR-IRSA, 2007; MATTM, 2010). A riffle-pool sequence (mesohabitat scale) was identified in a river section of about 25-50 meters. Microhabitat proportions, in terms of organic and mineral substrate types, were then visually estimated, and invertebrates were collected according to their proportional presence for a total of 10 sampling units in pool and 10 in riffle mesohabitats, respectively (see Buffagni, 2021 for details on sampling design). For this dataset, only samples collected in the pool mesohabitat are considered. Invertebrates were quantitatively collected in each sampling unit using a Surber net (area 0.05 m2; mesh size 0.5 mm), positioned on each microhabitat, with the opening directed against the main water flow direction and the substrate contained within the area delimited by the sampler is disturbed by hands or feet to dislodge the organisms from the substrate. The collected organisms were then transferred to dedicated buckets or trays, sorted from the substrate, identified, counted and then placed in vials and preserved in alcohol.
Quality Control: Quality control for geographic data: Reliability of coordinates was checked in QGIS. Geographic coordinate format, coordinates within country/provincial boundaries, and the absence of anomalous ASCII characters in the dataset were also double checked. Quality control for taxonomic data: even if some taxa have undergone a nomenclature revision, the nomenclature used in this dataset followed the one present in the MacrOper list (Buffagni & Erba, 2014), used to assess the ecological status of Italian water bodies according to the WFD. Specimens were assigned to taxonomic units according to the available literature and identification keys. Identifications were internally checked.
Method Steps: Main underlying purpose was to characterise the benthic aquatic assemblages and investigate the relationship between benthic community, riverine habitat features and ecological status assessment. Along with sampling of the invertebrate benthic community, several abiotic features at different spatial scales (e.g. microhabitat composition, water quality, land uses) were also recorded. Local hydro-morphological characterization of each river reach was also performed following the CARAVAGGIO (Core Assessment of River hAbitat VAlue and hydro-morpholoGIcal cOndition) method (Buffagni et al. 2013; see also Buffagni, 2021).
