AuthorshipSCIMAGO INSTITUTIONS RANKINGS

    ABSTRACT

    This work was carried out under the hypothesis that there is a growing loss of diversity in communities of tardigrades, from rural to urban areas, increasing the homogenization of its communities due to the urbanization. Samples were taken from the city of Salta in areas with high vehicular traffic and samples in surrounding rural areas. We identified a total of eight species/morphospecies. The inventory completeness was greater than 94%. The rural community was more diverse and structurally more uniform compared with the urban one, shown that both communities were different. Macrobiotus hufelandi Schultze, 1834 results as an indicator species, and Milnesium sp. as detector species from urban habitat; meanwhile Paramacrobiotus areolatus Murray 1907 was an indicator species for rural areas.
