(Pollen analysis of honey and beebread derived from Brazilian mangroves). Pollen analyses were performed on honey and beebread from hives in apiaries located in two distinct mangrove areas dominated by Laguncularia racemosa (L.) C.F. Gaernt. one apiary was located at the edge of Guanabara Bay, rio de Janeiro state, and the other near Maranguá Bay, Bahia state, Brazil. We investigated the contribution of nectar and pollen from mangrove vegetation to Apis mellifera L. honey and beebread stocks. Intensive visitation to this plant species by honeybees and the presence of its pollen grains in honey and beebread confirmed the importance of Laguncularia racemosa as a polliniferous and nectariferous species.
