Abstract
Disturbances, like fire represent a source of danger for the paramount and its ecosystemic services. One of the main services that insects provide for this ecosystem is pollination. To measure the effects of fire over bee communities in the grasslands of Ecuadorian paramount, a total of 60 traps (pan trap, yellow, white, and blue) were distributed across the two treatments considered for this study: burned grasslands and conserved grasslands in Atacazo volcano, Pichincha, Ecuador. Samples were collected from March to May 2021. We collected a total of 149 individuals, those belong to 8 species of 5 different genera. Species accumulation curve suggests that species richness is higher in burned grasslands than in conserved grasslands. There were not differences in the dominance, but the entropy was higher in the conserved treatment. The species composition was similar with a lot of overlapping in both treatments. This results suggest that there are not significant differences in the comparison between burned grasslands and conserved grassland.
