Chironomids and oligochaetes in the subalpine Lake Maggiore littoral area: a first dataset

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 600 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.

Sampling Methods

Macroinvertebrates sampling was performed following the standard sampling methodologies developed within NIVA and, more recently, ICP WATERS Manuals and Programmes (NIVA 1987; ICP Waters Programme Centre 1996, 2010).
Semi-quantitative macroinvertebrate samples were taken in July, August and September during the period 2019-2021. Two habitats with different conditions at each site (Magadino-MA, Fondo Toce-FT, Sesto Calende-SC) were monitored: a permanently flooded throughout the year (namely wet, and the dataset referred as "W") and a habitat occasionally subjected to drought during low lake water levels (or dry, in the dataset referred as "D"). In total 100 samples for macroinvertebrates were sieved with a 250 μm mesh size to eliminate the finest fractions of sediment and then fixed with ethanol (80 %) and placed in plastic bottles.

Method step description:

1. In the lab the entire samples were sorted under a stereo-microscope and all organisms were subdivided into main taxonomic groups using Italian macroinvertebrate identification guides. Species identification was performed by preparing Faure slides mounts of head for chironomid larvae and front end with chaetae distribution and genital apparatus for oligochaetes (Timm, 2009). Identification was performed to species level whenever possible, using relevant taxonomic keys (e.g. Andersen et al., 2013; Timm, 2009). The genus level was considered when available material (presence of immature or poorly preserved specimens) hinders species identification.
   In total 9685 specimens were identified and 373 records of Chironomidae larvae and 227 records of Oligochaetes were included in the dataset.
   Finally, data for 6 georeferenced points (MA:W, MA:D, FT:W, FT:D, SC:W, SC:D) and data of triplicates (R1, R2, R3) per each point were included in the dataset.
