ABSTRACT The late Quaternary evolution of central‐eastern Brazil has been under‐researched. Questions remain as to the origin Cerrado, a highly endangered biome, and other types vegetation, such Capões – small vegetation islands semi‐deciduous mountain forests. We investigated factors that influenced expansion contraction Cerrado during (last ~35 ka), using multi‐proxy approach: stable isotopes (δ 13 C, δ 15 N), geochemistry, pollen multivariate statistics derived from peat core (Pinheiro...

Abstract Orchid bee species are important pollinators in the Neotropics. While male orchid bees known to have a close interaction with odor-rewarding flowers, females often pollen generalists. In current study, we investigated differences diet diversity of various vegetation types and across sites varying levels forest cover by means an analysis frass pellets bee, Euglossa cordata (Linnaeus, 1758), multiple based on literature review. The grains found inner part brood cells were used assess...

The presented paper considered the pollen morphology of thirteen species belonging to seven genera Fabaceae family occurring in Pau-de-Fruta Special Protection Area (SPA), Diamantina, state Minas Gerais, Brazil. grains six Chamaecrista [C. cathartica (Mart.) H.S. Irwin & Barneby, C. debilis Vogel, flexuosa (L.) Greene, hedysaroides (Vogel) glandulosa and papillata Barneby] have a similar morphology, characterized by three long colporated apertures with central constriction. share specific...

This study shows the influence of climatic factors and nectar pollen collection by Melipona quadrifasciata in a natural habitat. Five colonies were studied Parque das Neblinas, Mogi Cruzes district (23o44’52”S/46o09’46”W), from October 2009 to September 2010. The flight activity bees was observed monthly, temperature relative humidity registered using dataloggers loads analyzed. peaks occurred between 8:30-9:50am, while is gathering along day. relation resources sampling environmental best...

SUMMARYWe performed palynological analyses of honey and pollen samples from Apis mellifera situated in a mangrove belt Guanabara Bay, state Rio de Janeiro, Brazil. Laguncularia racemosa is the most abundant species this area; some individuals Avicennia tomentosa also occur. Pollen analysis showed that bees visited ruderal plant species, grasses crops for pollen. We recognized 27 types belong to 22 families. The frequent polliniferous Asteraceae, Euphorbiaceae, Fabaceae, Myrtaceae Arecaceae....

A metodologia detalhada a seguir foi definida pelos autores durante reuniões organizadas em Belo Horizonte por ocasião do 3f? Congresso da Associação Brasileira de Estudos Quatemário (ABEQUA) 1991. Consiste na padronização dos métodos coleta e tratamentos físico-quúnicos serem aplicados preparação das amostras destinadas estudos Palinologia. É recomendada para palinológicos relacionados com o deverá ser utilizada sempre que for possível, finalidade permitir uma comparação entre os trabalhos...

SummarySeven samples of Brazilan red propolis were analyzed using palynological methods. The originated from the northeastern coastal region Brazil; three Alagoas, Bahia and one Paraíba state. Glandular trichomes absent in propolis, as sand, earth, quartz starch grains that normally occur geopropolis. presence pollen Schinus ("aroeira") was considered characteristic sediments. quantity Protium (Burseraceae), another possible resinous plant taxon, very small when compared with Schinus. This...

Abstract Pollen types present in samples from corbiculae of Melipona capixaba (Moure and Camargo) (Hymenoptera: Apidae: Meliponina) worker bees were analyzed, as well pollen food pots inside the hives three sites located at bees' original habitat. The aim was to find out sources used a trophic resource by this species. dominant grains spectrum belonged families Myrtaceae Melastomataceae. Eucalyptus most frequent type Conceição do Castelo municipality; Eucalyptus, Myrcia,...

Pollen samples were collected in three different periods from 11 Melipona capixaba Moure & Camargo hives and analyzed with melissopalynological methodology. A total of 33 pollen types identified, which 23 genera 15 families identified. The following showed the highest richness: Fabaceae (7), Myrtaceae (3), Solanaceae Arecaceae (2), Asteraceae Euphorbiaceae Melastomataceae/Combretaceae Rubiaceae Sapindaceae (2). most frequent (>45%) Eucalyptus , generated great similarities between...

The sediments of 10 samples geopropolis collected from 3 species Meliponinae in the states Espírito Santo, Minas Gerais and São Paulo, Brazil, obtained after chemical treatment, were analysed. Pollen grains, hyphae spores fungi, organic material burned plant fragments observed majority samples. Sandy or earth materials was present all sediments. analysis identified dominant, accessory isolated taxa occurring areas sample recovery. most important pollen types found Eucalyptus (Myrtaceae)...

Pollen load samples from 10 hives of Apis mellifera (L.) were analyzed based on their physicochemical composition and botanical source, considering color as a parameter for quality control. In seven it was possible to establish the occurrence more than 80% single pollen type, characterizing them unifloral but with protein content variation. One exclusively composed saprophytic fungi (Cladosporium sp.). Comparing mean results loads those nutritional components load, former presented higher...

Samples of commercially available bee pollen loads or pellets, denoted by common names and presenting several colours, were examined using analysis in order to obtain their botanical regional origin. Two grammes each the nineteen well-mixed samples, comprising ca. 300 used. Each sample was grouped into subsamples considering colour that weighed again. Pollen slides prepared without use acetolysis. Thirteen samples presented a dominant type equal more than half sample’s weight. The may be...

O experimento foi realizado dois apiários distintos, cada um com cinco colmeias. As cargas retidas nos coletores pólen instalados nas colmeias foram analisadas quanto à origem botânica. plantas floração no entorno dos coletadas identificadas. A maioria das abelhas Viçosa era nativa, localizada jardins hábito arbóreo. Pela análise...

Due to their ecological and economic importance, honey bees have attracted much scientific attention, which has intensified due the recent population decline of these insects in several parts world. Among factors related patterns, infection by pathogens are most relevant, mainly because easy dissemination microorganisms. Although no zoonotic diseases associated with insects, presence infectious agents bee products should still be considered they play a role as disease dispersers, increasing...
