During the last decades, many areas of the Amazon region were deforested to be used by agricultural activities. However, when conditions are not suitable for development of the activities, these areas are abandoned and start the process of secondary forest succession and vertebrates and invertebrates respond differently to this process. Euglossine bees are known as orchid bees and males and females of these bees are considered important pollinators in tropical forests. This work has as main objective to verify the effects of forest succession on Euglossina. More specifically, verify the changes in communities after 30 years of isolation areas and how these bees are influenced by floristic composition, vegetation structure, complexity and heterogeneity of the environment. The study was conducted in the Biological Dynamics of Forest Fragments Project (BDFFP). Males of euglossine were collected in traps containing odoriferous substances attractive. A total of 2,226 individuals belonging to four genera and 40 species of euglossine were collected. For vegetation, 1701 trees were identified belonging to families 41 and 146 species. When the results were compared with other studies conducted in the same area, it was found that there were changes in the composition of Euglossina. The successional stage of the areas was positively correlated with the diversity of Euglossine and negatively correlated with dominance. The geographical distance did not influence the similarity faunal, floristic and structural areas. The diversity of bees was positively correlated with the richness and diversity of plants. In this study, vegetation structure, the complexity and heterogeneity were the factors that most contribute to community Euglossina. |
