Dataset_Biodiversity_River_Po_Macroinvertebrates_2020

The data set consists of 41 columns per 130,727 records. The first column reports the ID Code of each record. The successive six columns are a rank-based taxonomical classification including the categories of Kingdom, Phylum, Class, Subclass, Order, Family, when known and available. Then, one column reports the taxon name and one column the unique identifier for the occurrence of Global Biodiversity Information Facility database (GBIF, 2020). The following eight columns refer to: Frequency (expressed as absolute abundance and referred to the sampled area), Sampled Area, Sample code, Site code, Sampling date (as dd/mm/yyyy) and Sampled mesohabitat (Riffle, Pool or Generic). The next seventeen columns report the sampled microhabitat expressed as percentage, classified in nine mineral substrate classes and eight biological substrates as included in the national standardised method (ISPRA, 2014). The remaining seven columns refer to: Human impacts in the site (present or absent), Administrative Region, River Name, geodetic Datum, Longitude East and Latitude North and Altitude (as m a.s.l.).
