This thesis is aimed at characterizing, through Palynology, the honey and pollen provisions in colonies of Tetragonisca angustula (Apidae, Meliponini) from Amazon and caatinga (dryland) regions in Brazil. One-hundred and three samples (57 of honey and 46 of pollen) were collected between September 2010 and January 2012 in meliponaries located in the Lower Amazon region, Pará State, and caatinga vegetation in Bahia State, Brazil. All samples were processed through acetolysis. At least 500 pollen grains were identified and counted per sample. T. angustula's honeys from the Lower Amazon region were characterized by the Borreria verticillata, Byrsonima, Cecropia, Clidemia, Eriope, Microtea, Myrcia, Solanum, Tapirira guianensis and Warszewiczia coccinea pollen types. In these honeys, the pollen concentration ranged from 20,000 to 500,000 pollen grains per 10 g of honey. Honeys from caatinga presented the Heteropterys, Mikania, Mimosa tenuiflora, Myrcia, Prosopis juliflora, Schinus, Senna macranthera, Solanum, Syagrus coronata and Solanum pollen types. On the other hand, pollen pots from the Lower Amazon showed the Acalypha, Byrsonima, Brosimum paraense, Borreria verticillata, Cecropia, Clidemia hirta, Davilla kunthii, Eriope, Lindackeria paludosa, Myrcia, Schefflera morototoni, Tabebuia, Tapirira guianensis and Vismia guianensis pollen types in their composition. The pollen pots from caatinga were characterized by the Prosopis juliflora and Solanum pollen types. Moreover, the Poincianella pyramidalis and Senna macranthera pollen types were considered indicators of caatinga dry vegetation. Regarding the most representative pollen types (>10%), the honeys from the Lower Amazon and caatinga revealed 23 and 16 pollen types, respectively. Meanwhile, the pollen pots samples showed 18 and 11 pollen types, respectively. The Fabaceae family stood out in all palynological analyses from both biomes because of its high amount of pollen types. The trophic niche size obtained was higher for the honey pots than for the pollen pots. The evenness points toward homogeneity in the use of floral resources by Tetragonisca angustula. For grouping the samples by geographic region, cluster analyses presented more consistent results when pollen spectra of honeys were used. This work represents the first contribution to Melissopalynology of the Lower Amazon region, Pará State, Brazil. |
