Abstract:
This review includes all the studies performed in the state of Paraná, Brazil, which had data on earthworms. A literature review was done for all publications (journal articles, dissertations, theses, conference proceedings, book chapters) carried out in the state of Paraná, Brazil, which had data on earthworms. The period evaluated ranged from 1986 (earliest date in the state) to 2020. Searches were performed in online databases including Sicence Direct, Scielo, CAPES and the digital collection of dissertations and theses from Brazilian Universities (BDTD).Overall 51 publications had earthworm data, including abundance, biomass, species, richness or just presence/absence. The soil chemical and physical analysis data were included in the dataset when performed in the same places as the earthworm sampling. Chemical data included: pH, H+Al, K, Ca, Mg, P, C, sum of Bases, CEC, Base saturation, N, Na. Physical data included: sand, clay and silt proportions, texture, porosity, density and resistance to penetration.
The data available in SoilHive is a subset containing only precise coordinates, containing at least three decimal points.
