In this study, we sampled grazed natural grassland and agropastoral systems in two regions (Alegrete and Aceguá) in the highly diverse Brazilian Pampa region which is undergoing significant change in land use cover. By hand sorting the soil, a total of five species were found, belonging to the families Glossoscolecidae (Glossoscolex sp.50 and Glossoscolex sp.51), Ocnerodrilidae (Kerriona sp.6 and Eukerria sp.3), and Lumbricidae (Aporrectodea trapezoides). The former four were identified as native?new to science?and the latter as exotic. Differences were observed in both earthworm species richness and abundance between regions and land-use systems, likely due to environmental conditions and agricultural practices, respectively. Agropastoral systems had higher abundance and species richness than natural grasslands, though these differences varied by location. This suggests that conversion from natural grassland to agropastoral systems can maintain native earthworms and, possibly, enhance ecosystem services. However, an exotic species was found in high abundance at one agropastoral site. These results highlight the need for additional biodiversity studies on earthworms in the Brazilian Pampa and for research on the impacts of land use changes in this region. |

Evaluation of physical and chemical parameters of accelerated composting of carcasses of dead pigs in rotary drum reactors: Rotary drum reactors are used to process pig carcasses in southern Brazil, which is the largest pig producing area in the country. The objective of this study was to evaluate physico-chemical parameters during accelerated composting of pig carcasses in a rotary drum reactor. For the experiment, a rotary drum reactor with a volume of 3.6 m3 was used, equipped with a continuous ventilation system that renewed air inside the reactor. The reactor was programmed to alternate between 24 minutes of rotation and 3 hours of rest. The reactor was operated in batch mode and loaded with a mass ratio of sawdust to pig carcass of 1.28. Biomass was collected weekly during the experimental period (8 weeks) for analysis of dry matter (DM), C (carbon), N (nitrogen) and pH. Temperature of the biomass was measured daily at 5 points inside the reactor. Over the experimental period, biomass DM decreased by 46.9%, mainly due to emission of C-CO2. Concentrations of C and N decreased from 52.7% and 2.94% of DM, respectively, to 45.5% and 0.8% of DM, respectively. The temperature of the biomass showed the characteristic behaviour of composting, remaining consistently above 50°C for 20 days. This technology has shown promising results, but modifications are needed to reduce N losses from the biomass during the process. |
