Earthworm populations have been little studied in forest systems in South America, and the choice of appropriate sampling methods is an important factor to consider. Hence, the present study evaluated earthworm populations using two methods: handsorting of large soil monoliths (40 × 40 cm × 20 cm depth), and application of formalin (0.5%) to the soil surface. Worms were sampled in fifteen areas at the Embrapa Forestry Research Station, including native Atlantic forest fragments, and native (Araucaria angustifolia) or exotic (Pinus elliottii) tree species plantations. Eight species of earthworms were collected overall, including four native species (Urobenus brasiliensis, Andiorrhinus duseni, Fimoscolex nivae and Glossoscolex embrapaensis) and one exotic (M. schmardae) in low abundance, and three other exotics in higher abundance (Pontoscolex corethrurus, Amynthas gracilis and Amynthas corticis). Total earthworm density ranged from 11.5 to 102 individuals m-2 and biomass from 5.6 to 31.6 g m-2, with higher values being found in P. elliottii plantations. Handsorting was more effective than formalin for sampling earthworms, resulting in higher species richness, overall abundance and biomass (particularly of the endogeic P. corethrurus) in both Pine and Araucaria plantations. Formalin extraction was better for extracting epi-endogeic species (particularly M. schmardae). Eveness and A. corticis densities were higher in native forests, while A. gracilis abundance was higher in Araucaria plantations and P. corethrurus predominated in both plantations, likely due to soil-related differences between the vegetation types. Earthworm population assessments in Brazilian forest systems should prioritize handsorting, while biodiversity inventories may benefit from combining handsorting with formalin extraction.

Biomass sorghum is an alternative feedstock to cogenerate energy and produce second-generation ethanol. The aim of this study was to evaluate the Genotype by Environment Interaction (GEI) in biomass sorghum and to identify the hybrids that associate high adaptability and stability using the Toler nonlinear regression, the Genotypes plus Genotype by Environment (GGE) biplot, and the Annicchiarico recommendation index. Thirty-three experimental photoperiod-sensitive single-cross hybrids and three checks were evaluated in relation to the traits: flowering time, plant height, moisture content, green mass yield, and dry mass yield. It was observed that the effects of hybrids, environment, and GEI were expressive. The GEI was predominantly complex for the traits related to the biomass yield. The Toler, GGE biplot and Annicchiarico methods show complementarity. The experimental hybrids 1, 8, 22, 31 and 33 are promising because of associating stability and lower recommendation risk. The hybrids 1 and 8 present broad adaptability, while the hybrids 22, 31 and 33 exhibit specific adaptability to high quality environments. |
