Resumo
Resource availability is an important predictor of abundance and species
richness. In this paper we veri!ed why there is local variation in bee diversity
testing the hypothesis that bee species richness and abundance will increase
with increasing resource availability. Resource availability was considered here
as the number of "owering plants and the number of plant species. Sampling
was carried out at two sites in Brazil, the quartzitic range (Ouro Branco) and
metaliferous !elds (Ouro Preto). At these sites ecosystems are endangered by
high anthropogenic impacts, particularly due to mining and urbanization. #e
samples were collected for 10 months in each site, twice a month, from 8:00
am to 5:00 pm. #e bees belonged to 77 species and 5 subfamilies. Bee species
and abundance increased with the increase in the number of plant species
and plant abundance at both sites. Bee richness and abundance were higher in
Ouro Branco than in Ouro Preto. Our results showed that bee diversity may
be regulated by resource availability.
