Conteúdo: |
Brazil is a megadiverse country from which around 10% of all species are known. However, many areasin Brazil have not been adequately studied, particularly for soil animals. This includes the state of SantaCatarina, where only 18 of the approximately 300 known Brazilian earthworm species occur, and wherevery little is known of the impacts of land use management on earthworm populations (density anddiversity). Therefore, the aim of this study was to evaluate earthworm species richness in five differentland-use systems (LUS) with increasing anthropogenic impact: native forest (NF), eucalyptus plantation(EP), pasture (PA), integrated crop-livestock (ICL) and no-tillage cropping (NT), in six counties, threeeach from the Western and Plateau regions of the state. Nine monoliths of 25 cm × 25 cm × 20 cm depthwere sampled at each site and worms hand sorted. Qualitative samples were also taken by digging atleast 20 holes per site to improve the likelihood of collecting rare species. Samples were taken in theWinter and Summer months of 2011?2012 (July?August 2011, December 2011?January 2012). Contraryto expectations, species richness was higher in LUS with higher (ICL and NT = 15 and 17 spp.) vs. loweranthropogenic impacts (EP, PA, NF = 9?10 spp.), mainly due to the presence of exotic species in the crop-ping systems. Native species predominated in PA and NF, although natives were also found in highlydisturbed ecosystems (NT, ICL) and in the West region all worms collected in NT were native. In total24 species were identified in all LUS, with 19 native species, including several that were new to science.Several species were collected exclusively in each region, and overall qualitative samples yielded 24species while quantitative samples only 16. Therefore, qualitative sampling appears to be more effectivein determining earthworm species richness at regional levels, although quantitative samples are a usefuladdition when LUS are compared within a region, and if abundance and diversity index calculations areneeded.
