Pollen analysis was employed to study the diet composition of two wild bees in a patch of temperate grassland invaded by exotic plants. Thirty pollen types from 14 families and two unidentified types were present in the seven samples analyzed. The three samples from Megachile pusilla Pérez were composed of 100% Lotus glaber and the four samples from Xylocopa ciliata Burmeister of abundant pollen (˃5%) of Lotus glaber, Galega offi cinalis, Adesmia bicolor and type Senna-Chamaecrista (all Fabaceae). The latter resource likely foraged out of the park, which could be an evidence to support its pollen preference for Fabaceae. However, a larger number of samples is necessary to identify the specialization status of X. ciliata. The preference for Lotus in this site was due to temporal specialization as M. pusilla was identified as polylectic in its origin area, and this could help to explain its eff ective naturalization in the New World and other areas of the Old World.

Honey is a natural product widely used by humans due to its sweet taste and health benefits produced by bees from nectar and honey dew of various plants. To establish and increase the production of honey one must know the plants that take part in the production of honey. In this study pollen analysis of forest honey samples from northern part of Malaysia was carried out to determine the botanical sources playing role in the production of honey in that region. The pollen samples were acetolyzed and identified microscopically. Out of the three samples studied Baling sample was unifloral having Mimosa scabrella as predominant pollen while Jeli and Gerik samples are multifloral containing Tipo myrcia and Elais guineensis as major secondary pollen. Fabaceae family represented four pollen types and accounted 80% of pollen in Baling sample and 34 % in Gerik sample while completely absent in Jeli sample. These results showed the dominance of plants from Fabaceae family in honey production. All the samples analysed have Albizia falcataria, Eupatorium sp., Sparganium typha, Tilia sp. and Tipo myrcia in common indicating that these plants are present in all the three places and these results also can be used as a tool in geographical identification of North Malaysian honey from others.

Knowledge about the botanical source of honey is very important for the beekeeper while it indicates adequate and abundant supply sources of nectar and pollen for the bees, thus contributing toward improved yield. The present study means to identify the pollen types occurring in 58 samples of honey produced in two states of the northeastern region of Brazil, Piauí (38 samples) and Ceará (20 samples), and to verify the potential of the honey plants during the months of February to August. The samples were obtained directly from beekeepers in each state and analyzed at the Apiculture Laboratory of the Entomology Section of Escola Superior de Agricultura "Luiz de Queiroz", USP, Piracicaba, State of São Paulo, Brazil. The pollen analysis was performed using the acetolysis method. The samples were submitted to both a qualitative and a quantitative analysis. The dominant pollen in the State of Ceará is from Mimosa caesalpiniaefolia, M. verrucosa, Borreria verticillata, Serjania sp., and a Fabaceae pollen type, while in the State of Piauí it is from Piptadenia sp., M. caesalpiniaefolia, M. verrucosa, Croton urucurana and Tibouchina sp.

Pollen Preservation

A pollen analysis of acid clays under brigalow is presented. The pollen fluxes in a first pair of soil profiles throw light upon the natural history of one locality as regards both its modern vegetation and the physical stability of gilgai. Fluxes in the relative pollen preservation indicate intensity of biological attack on the exine. In a profile representative of the higher level, preservation is good enough, erosion or fill on a micro-scale so slight, and any vertical down-wash so slow as to show up residual flux variations from successional change. But under this natural canopy, even though there is only a very slow wash of litter and soil down to the bottom of the depression, a faster tempo of decay than any in the higher ground, and physical incorporation down deeper cracks, maintain a balance that prevents accumulation on an almost bare surface. This shows up in deeper penetration of pollen grains, in even the residual pollen types being severely eroded, and in irregular fluxes in which the successional trace is lost. Presumably, old Myrtaceae types have washed out of the soil above. The pollen fluxes indicate a natural replacement of eucalypt forest by brigalow some time before clearing. The expanding fluxes at the immediate surface are taxa from outside the forest, particularly the Chenopodiaceae, that would have become more abundant after clearing. Insight into soil stability comes from the marked contrast in the distribution and the preservation of the pollen grains across the microrelief. The higher level is physically more stable than the bottom of the adjacent depression. Depressions are surprisingly dry in natural forest, but these pollen fluxes suggest that they are occas- ionally the wettest microenvironment.

The aim of this study was to investigate the polliniferous floral sources used by Apis mellifera (L.) (africanized) in an apiary situated in Pará de Minas, Minas Gerais state, and evaluate the pollen prefences among the beehives. Two beehives of Langstroth type with frontal pollen trap collectors were used. The harvest was made from September 2007 to March 2008, with three samples of pollen pellets colected per month per beehive. The subsamples of 2 grams each were prepared according to the European standard melissopalynological method. A total of 56 pollen types were observed, identifying 43 genus and 32 families. The families that showed the major richness of pollen types were: Mimosaceae (8), Asteraceae (6), Fabaceae (3), Arecaceae (3), Euphorbiaceae (3), Rubiaceae (3), Caesalpiniaceae (2), Moraceae (2) and Myrtaceae (2). The most frequent pollen types (> 45%) were Mimosa scabrella, Myrcia and Sorocea. The results demonstrated a similarity regarding the preferences of floral sources during the major part of the time. There was a distinct utilization of floral sources among the pollen types of minor frequency. In spite of the strong antropic influence, the region showed a great polliniferous variety, which was an indicative of the potential for monofloral as well as heterofloral pollen production.

Six morphological types of Polemonium pollen are described, including P. micranthum which is the only taxon considered to be consistently identifiable to species. A key to the pollen types as seen in light microscopy is presented along with light and scanning electron micrographs of each type. The palynological evidence supports the taxonomic treatment of P. uciitiflorum and P. occidentale as subspecies of P. caeruleum, and supports a close affinity between P. pectinatum and P. foliosissimum. Brief summaries of the present-day ecology and distribution of Pacific Northwestern Polemonium species are presented. The application of indicator pollen analysis in Quaternary paleoecology is discussed, with special references to examples of paleoenvironmen-tal inference using Polemonium pollen types.

The Poço das Antas National Biological Reserve is located in Rio de Janeiro State, southeast Brazil. This paper presents information on past environmental characteristics of the area through pollen analysis. Two sedimentary columns were collected and five samples were selected for radiocarbon dating. The following ages of the columns from bottom to top were detected: column 1 - 1.20-1.16 m: 6080 ±40 years BP, 0.775-0.735 m: 4090 ±40 years BP, 0.385-0.345 m: 1880 ±80 years BP; column 2 - 1.22-1.18 m: 3520 ±40 years BP, 0.23-0.19 m: 1810 ±40 years BP. Three samples from column 1 and two samples from column 2 were selected for pollen analysis: 1.20 m, 0.77 m and 0.37 m of column1 and 1.22 m and 0.21 m of column 2. Chemical treatment followed standard methodology. The palynological analysis shows that around 6080 years BP the study area was dominated by a rain forest and from around 4090 years BP the vegetation changed to a fragmented forest, restricted to low hills and surrounded by an open area of grassland and pioneer plants, swamps and peat areas. The pollen assemblage of the samples 3520, 1880 and 1810 years BP suggest the permanence of this kind of vegetation between 4000 years BP and the actual.
