Euglossini bees are important components in a community as they are important pollinators for economically valuable plants as well as hundreds of orchid species. However, some species(More)
The use of trap nests supplies important biological information concerning the biology of bees and wasps. However, the knowledge about the factors that influence the management of these groups is still scarce. Our study aimed to analyze the effects of the orientation of nest entrance, shading, and block material (wood or vermiculite) on the frequency,(More)
Software ecosystems as a paradigm for large-scale software development encompass a complex mix of technical, business, and social aspects. While significant research has been conducted to understand both the technical and business aspects, the social aspects of software ecosystems are less well understood. To close this gap, this paper presents the results(More)
Knowledge of the spatial variability of soil properties and of forage yield is needed for informed use of soil inputs such as variable rate technology (VRT) for lime and fertilizers. The objective of this research was to map and evaluate the spatial variability of soil properties, yield, lime and fertilizer needs and economic return of an alfalfa pasture.(More)
