A nova cultivar Embrapa 42 (Triticum aestivum L.) foi desenvolvida pela Embrapa Cerrados, Planaltina-DF e Embrapa Trigo, Passo Fundo-RS. Originou-se do cruzamento entre as linhagens LAP 689 (Arthur Type*2/7 Cerros//Ter/Bulgaria 88/3/Ciano/Inia) e MS 7936 (Kavkaz/Tanori//Tito sib). Sendo recomendada para plantio no sistema de cultivo irrigado por aspersao, na estacao seca, no estado de Goias e no Distrito Federal, desde 1994. Essa cultivar destaca-se por apresentar alto potencial de rendimento de graos, altura media, ciclo precoce e resistencia ao acamamento. Quanto a qualidade industrial e um trigo de gluten forte e estabilidade alta, que conferem a ela uma classificacao de trigo melhorador. Em relacao ao rendimento de graos, na media de 11 experimentos conduzidos em 1993 e 1994, superou a melhor testemunha (Embrapa 22) em 3%. |

Managed forests are important landscape components in tropical regions and may contribute to biodiversity conservation. Yet, managing tropical forests sustainably requires an understanding of ecosystem responses to silvicultural interventions. We investigated how silvicultural intervention intensity affects tree species composition and diversity over 30 years in the Brazilian Amazon by comparing them to pre-logging conditions and to an unlogged control. The interventions comprised logging in 1982 and thinning in 1993?1994 and ranged in intensity from 19 to 53% reduction in the original basal area (BA). Trees with a diameter at breast height (DBH) ≥ 5 cm were measured on eight occasions in 41 permanent sample plots of 0.25 ha each. Silvicultural intervention intensity influenced both tree species composition and its trajectory within 30 years. In contrast, tree species diversity was not impaired. High intervention intensities (with BA reduction > 6.6 m2 ha− 1) had a substantial influence on the community of trees (DBH ≥ 10 cm), which did not show signs of return to pre-logging species composition. The reduction of BA through harvesting damage and thinning had a stronger effect on species composition than logging of mature trees itself. Thus, damage should be kept to a minimal level and strong thinning interventions should be avoided. This may enhance ecosystem recovery and maintenance of biodiversity at other trophic levels. Since current permitted harvesting intensities in the Brazilian Amazon are lower than the lowest intensity examined in our study, legal harvesting practices are unlikely to cause substantial, long-term changes in tree species composition.
