This study aimed to investigate differential allele expression (DAE) and polymorphism and parent-of-origin effects on expression of genes related to beef traits. CAST, related to meat tenderness, and DGAT1 and leptin, related to fat deposition, were evaluated. In bovine fetal tissues CAST was expressed twice as much (Pb0.05) in muscle of homozygous GG than in heterozygous AG. Leptin was expressed about one-tenth as much (Pb0.05) in heterozygous TpCm (allele T of paternal origin and allele C of maternal origin) than in homozygous CC. No DAE was observed. The evidence of polymorphism effect on expression of CAST and parent-of-origin effect on leptin contributes to a better understanding of events controlling the expression of genes of economic interest in cattle. Furthermore, if the parent-of-origin effects observed in fetal tissues are confirmed in adult tissues and associated to phenotypic variation, this parental origin criterion may be considered in marker-assisted selection of beef traits. |

The conventional agriculture production uses chemical products, tillage and other technics harmful
to the soil and health the living beings. Because of that grown producers have been looking for
alternative approaches of production. Otherwise, there are few studies about monitoring of soil
quality, which may subsidize the management of natural resources in agroecologic systems.
This work aimed to the evaluate of the soil quality in agroecossystems, using ants as ecologic
bioindicators. Ants has big potential as bioindicators because they are insects with high
geographical distribution, easy sampling and sensitive to environmental changes. Samples were
collected on four rural properties localize in three municipalities of the state of Paraná (Rio Azul,
Porto Vitória e Biturana), Brazil using the TSBF method (ANDERSON & INGRAM, 1993) with
parcels of 25 x 25cm and 0-10, 10-20 and 20-30cm depth, with five replicates per area. The soil
of three areas were evaluated: corn monoculture, corn intercropped with green manure and
forest area near the cultivated areas. In all properties, the forest area had diversity index and
species richness of ants higher than the cultivated areas. This aspect is important in agroecologic
systems, because the forest areas act as ?hot spot? of the species. In Biturana the forest area
had the highest species diversity of ants, indicating to be more conservated than in the other
municipalities. Although the distribution of the species did not clearly presented a standard in
relation to the use of green manure, probably as a result of the short time of use, some phenomena
were observed that better need to be investigated. MenosThe conventional agriculture production uses chemical products, tillage and other technics harmful
