Conservation, Diversity, Euglossini, Pollinators, Primary versus secondary forest


The fragmentation and habitat loss are the main causes of pollinators decline worldwide, however very little is known about the composition and distribution of neotropical pollinators along continuous micro-environments. To fill this gap, we carried out samplings of Euglossini bees in a continuous area of forest with micro-environments of primary (remnant) and secondary (regeneration) forest of Atlantic Forest. We evaluated the differences in the composition and uniformity of orchid bees in different micro-environments, in order to characterize the responses of the local environmental changes in the attraction of bees to chemical traps. Our results indicated that the composition and uniformity were similar between the two forest fragments studied here, although there are greater abundance of some species by micro-environments. We conclude that the characteristics of the sites in a continuous environment with primary and secondary forest do not seem to have an effect on the composition of the Euglossini fauna, and that the chemical substances are complementary in the attractiveness of the orchid bee males. Thus, our findings suggest that micro-environments in a continuous matrix near forest remnants can help to promote the reintegration of the orchid bee communities and contribute to the conservation of areas in process of forest regeneration.
