Este trabalho foi efetuado em uma parcela de 4 ha, cuja cobertura vegetal foi derrubada e queimada para plantacao de pastagem. A queimada nao foi homogenea, dando origem a um mosaico de manchas bem queimadas e nao queimadas. A fauna de invertebrados do solo foi comparada nestes dois tipos de manchas, coletando-se 15 unidades de amostras em cada um, transcorridos 1, 15, 30, 40, 60, 125, 145, 200, 270, 320 e 370 dias apos a queima. A amostragem foi feita com sonda metalica de 25 cm2, e a extracao da fauna, com funis de Berlese-Tullgren. Os resultados mostraram que a densidade populacional da fauna foi drasticamente afetada pelo fogo. Na area queimada, o numero total de Oribatida (46.464 ind/m2) foi menor que o numero total das outras subordens de Acari (132.532 ind/m2); a densidade de Collembola (7.361 ind/m2) foi inferior ao numero total dos outros insetos (22.460 ind/m2). Um quadro inverso observou-se na area nao queimada (Oribatida = 79.045 ind/m2; outros Acari = 34.025 ind/m2 - Collembola = 17.276 ind/m2; outros insetos = 11. 098 ind/m2). |

Abstract: Water availability, light, management practices, and harvest time impacts on Coffea arabica L. yield and bean quality remain uncertain. It was hypothesized that the soil water and light availability could impact berry distribution, yield, and bean chemical attributes within the plant canopy. Therefore, it was aimed to study berry yield, berry distribution, and bean chemical traits along the canopy strata of four coffee genotypes (Iapar 59, Catuaí 99 and two Ethiopian wild accessions, ?E083? and ?E027?), cultivated with (IRR) and without irrigation (NI) in the two initial harvest years. The maximum height of berry occurrence was lower in NI than in IRR plants in both harvest years. In the 2nd harvest year, higher leaf-to-fruit ratio was found under NI than under IRR for all genotypes, except for Catuaí 99, while the most regular berry distribution among canopy strata was obtained in IRR ?E083?, the highest bean yield in IRR ?E083? and Iapar 59, and the highest percent of useful bean biomass in NI Catuaí 99. The reduced lipid content under IRR was more important in the 1st (all genotypes) than in the 2nd harvest year (Iapar 59 and ?E027?). As a novelty, chemical bean composition was additionally impacted by light availability along the canopy strata. Proteins declined from bottom (shaded) to upper (highly light exposed) strata, regardless of genotype and harvest year. Similar stratification was observed in caffeine in the 2nd year. Although some traits were somewhat changed among strata, no substantial quality changes occurred, thus allowing that harvest might include the entire plant and not only some specific strata. Iapar 59 and ?E083? showed chemical composition usually associated with high bean quality, with the highest lipid, sucrose, and soluble sugar contents, and the lowest caffeine, chlorogenic acids, and phenolic components among four genotypes, but Iapar 59 plants were less affected in their yield under NI. Based on additional responses from space occupation and yield only under IRR, the wild accession ?E083? must be considered in future breeding programs as promising material for intensive input conditions. High bean quality and the less variated yield under lower soil water availability qualified the Iapar 59 as the most prominent among the four genotypes.
