Los productores de plantas en vivero a menudo se enfrentan con diferentes problemas, la principal y no menos importante, es el uso adecuado de sustratos y fertilizantes para obtener plantas con calidad morfológica y fisiológica. El objetivo del presente trabajo de investigación fue evaluar el efecto de diferentes sustratos alternativos sobre el crecimiento inicial en vivero de Hymenaea courbaril L., producidas en bolsas negras de polietileno de 13 × 20 cm, calibre 500, Volumen 0.98 L. Se utilizó un diseño experimental completo al azar donde los sustratos fueron: tierra negra (testigo) (1), peat moss (1), aserrín de mango + arena de río (2:1), aserrín de mango + peat moss (2:1), tierra negra + peat moss + aserrín de mango (1:1:1) y tierra negra + aserrín de mango (1:1) respectivamente, dando un total de seis tratamientos. Se midió el diámetro del tallo (mm) y altura total (cm...

It is estimated that there are approximately 35,000 species of bees worldwide, including many that do not fit our concept of a bee. Among all this diversity, social bees account for only 9.4% of species. Among the main characteristics of these bees is that they live together, collaborate and are very communicative among the members of the hive, sharing their findings and daily work activities. In this sense, with the research that has been carried out on communication in social bees, we know that they maintain an organized system, or rather divided into hierarchies, to share information accurately, and carry out important events such as mating, caring for the young, gathering food/ materials and the collective response to any danger. The study of these fascinating "forms of communication" in bees allows us to know in detail the innards of the life of social bees and to learn even more ab...
