ABSTRACT Flight activity of bees is influenced both by environmental factors and by internal condition of the colonies. Information about external activity of bees is very important, because it provides data of the species biology, supplying subsidies for the use of these insects in the pollination of crops. The present work aim to evaluate the flight activity of Geotrigona subterranea (Friese, 1901) (Hymenoptera: Apidae) in natural environment. This study was performed on the Instituto Federal do Norte de Minas Gerais, in the municipality Januária, Minas Gerais State. Two natural nests were observed. The activities of bees of the colonies were recorded three days each month, during the period of December 2011 to November 2012, totaling 924 observations....

Availability of a soluble phosphorus source applied to soil samples with different acidicity levels

Autores: Viégas,Ricardo Almeida; Novais,Roberto Ferreira; Schulthais,Fernanda.
Considerations on the interactions of P in the soil-plant system have a long history, but are still topical and not yet satisfactorily understood. One concern is the effect of liming before or after application of soluble sources on the crop yield and efficiency of available P under these conditions. The aim of this study was to evaluate the effect of soil acidity on availability of P from a soluble source, based on plant growth and chemical extractants. Nine soil samples were incubated with a dose of 200 mg kg-1 P in soil with different levels of previously adjusted acidity (pH H2O 4.5; 5.0; 5.5; 6.0 and 6.5) and compared to soils without P application. After 40 days of soil incubation with a P source, each treatment was limed again so that all pH values...

Anatomy and ontogeny of the pericarp of Pterodon emarginatus Vogel (Fabaceae, Faboideae), with emphasis on secretory ducts
Provedor de dados: 42
Autores: Paiva,Élder A.S.; Oliveira,Denise M.T.; Machado,Silvia R.
Discrepant and incomplete interpretations of fruits of Pterodon have been published, especially on the structural interpretation of the pericarp portion that remain attached to the seed upon dispersal. The present work clarified these doubts and analyzed ultrastructural aspects of the Pterodon emarginatus diaspores using light and transmission electron microscopes. Cell divisions are prevalent among the initial phases of development, and the subadaxial and adaxial meristems form the fibrous inner mesocarp and the endocarp composed of multi-seriate epidermis, respectively. At the median mesocarp, numerous secretory ducts differentiate between the lateral bundles, by lytic process. After lysis of the central cells and the formation of the lumen, the ducts...
