The aim of this study was to carry out a survey of the flora with potential for beekeeping in the counties of Ubiratã and Nova Aurora-PR through the collection of plants and pollen analyses in honey samples collected monthly. 208 species of plants were recorded, distributed in 66 families. The families that showed the major richness of pollen types were: Asteraceae, Myrtaceae and Solanaceae. Approximately 80 pollen types were found in honey samples, most of them were characterized as heterofloral. Cultivated plants, such as Glycine max (soybean) and Eucalyptus spp., were representative in some months of the year. Exotic species, such as Ricinus communis and Melia azedarach, were also frequent. However, over than 50% of the pollen types belong to native species of the region, such as Schinus terebinthifolius, Baccharis spp. Alchornea triplinervia, Parapiptadenia rigida, Hexaclamys edulis, Zanthoxylum sp. and Serjania spp., indicating the importance of the native vegetation for the survival of the colonies.

Biodiesel is a renewable fuel usually produced from vegetable oils and animal fats. This study investigates the extraction of oil and its conversion into biodiesel by base-catalyzed transesterification. Firstly, the effect of various solvents (methanol, n-hexane, chloroform, di-ethyl ether) on extraction of oil from non-edible crops, such as R. communis and M. azedarach, were examined. It was observed that a higher concentration of oil was obtained from R. communis (43.6%) as compared to M. azedarach (35.6%) by using methanol and n-hexane, respectively. The extracted oils were subjected to NaOH (1%) catalyzed transesterification by analyzing the effect of oil/methanol molar ratio (1:4, 1:6, 1:8 and 1:10) and varying temperature (20, 40, 60 and 80 °C) for 2.5 h of reaction time. M. azedarach yielded 88% and R. communis yielded 93% biodiesel in 1:6 and 1:8 molar concentrations at ambient temperature whereas, 60 °C was selected as an optimum temperature, giving 90% (M. azedarach) and 94% (R. communis) biodiesel. The extracted oil and biodiesel were characterized for various parameters and most of the properties fulfilled the American Society for Testing and Materials (ASTM) standard biodiesel. The further characterization of fatty acids was done by Gas Chromatography/Mass Spectrometer (GC/MS) and oleic acid was found to be dominant in M. azedarach (61.5%) and R. communis contained ricinoleic acid (75.53%). Furthermore, the functional groups were analyzed by Fourier Transform Infrared Spectroscopy. The results suggested that both of the oils are easily available and can be used for commercial biodiesel production at a cost-effective scale.

In Northwest Argentina, Yungas subtropical forests are very important because of their huge vegetal diversity. Honeybees (A. mellifera) use these resources to feed and therefore as an ecosystemic service through beekeeping. The characterization of pollen flora of a region allows getting to know the food source and defining the importance of different plant species for colonies development and maintenance. The aim of the present study is to identify the pollen flora used by A. mellifera in the Yungas western area in Jujuy (Argentina) by means of their pollen loads characterization and to analyze the variations of two consecutive productive periods throughout spring and summer. To do this, 14 samples taken monthly were analyzed over the periods from September 2011 to March 2012 and September 2012 to March 2013. The samples were obtained from pollen traps at the entrances of the hives and were treated in the laboratory under conventional melisopalinology techniques with subsequent acetolysis. A total of 46 pollen types belonging to 25 botanical families were identified. The most important ones according to the family importance index are Euphorbiaceae (35.54), Fabaceae (26.27), Asteraceae (20.77), Vitaceae (16.14), Myrtaceae (9.13). Zanthoxylum, Sebastiania, Mimosa, Euphorbiaceae, Cactaceae, Parapiptadenia excelsa, Eupatorium, Cissus, Eucalyptus y Viguiera were identified as dominant resources. The variations of the breadth Index trophic niche show a floral resources selection for the area, where the use of native species stands out. The information produced in this study contributes to the knowledge of the resource offered by the forest and the species that are important for beekeeping production. Besides, it contributes to enhance the production and marketing of this product from its added value, allowing beekeepers a good management of hives.

Knowledge of the flora that bees visit is important for characterization of their products and conservation of flora and fauna. Thus, this study identified the flora used by Apis mellifera L. (Hymenoptera: Apidae) during the honey production period through the pollen spectrum. Honey samples were collected at apiaries in the municipality of Cruz das Almas, Bahia, Brazil. International methods for samples preparation were used. ETOH was use for honey dilution and subsequently subjected to acidic treatment by the standard method of acetolysis. The pollen content resulting from the analysis was examined under an optical microscope, with separation and counting of pollen grains. Pollen types were identified by consultation and comparison to reference pollen collections and specialized literature. Twenty-seven pollen types distributed among 19 botanical families were identified in the sample set, and Fabaceae, Rubiaceae, Asteraceae and Sapindaceae were the families with a greater number of pollen types. The most frequent pollen types were Mimosa tenuiflora, Vernonia condensata, Bidens, Hyptis, Amaranthus spinosus, Schefflera morototoni and Serjania pernambucensis, all with relative frequency in samples equal to or greater than 70%. The honey evaluated showed a diverse pollen spectrum, evidencing multifloral characteristic.

Lectin histochemistry was used to perform in situ characterization of the glycoconjugates present in boar testis and epididymis. Thirteen horseradish peroxidase- or digoxigenin-labelled lectins were used in samples obtained from healthy fertile boars. The acrosomes of the spermatids were stained intensely by lectins with affinity for galactose and N-acetyl-galactosamine residues, these being soybean, peanut and Ricinus communis agglutinins. Sertoli cells were stained selectively by Maackia ammurensis agglutinin. The lamina propria of seminiferous tubules showed the most intense staining with fucose-binding lectins. The Golgi area and the apical part of the principal cells of the epididymis were stained intensely with many lectins and their distribution was similar in the three zones of the epididymis. On the basis of lectin affinity, both testis and epididymis appear to have N- and O-linked glycoconjugates. Spermatozoa from different epididymal regions showed different expression of terminal galactose and N-acetyl-galactosamine. Sialic acid (specifically alpha2,3 neuraminic-5 acid) was probably incorporated into spermatozoa along the extratesticular ducts. These findings indicate that the development and maturation of boar spermatozoa are accompanied by changes in glycoconjugates. As some lectins stain cellular or extracellular compartments specifically, these lectins could be useful markers in histopathological evaluation of diseases of boar testis and epididymis.

Abstract The drastic reduction of the Brazilian Cerrado has transformed this savanna hotspot into vast swaths of commodity-based agriculture fields, mainly soybean, sugarcane, and beef-production pasturelands. The resulting habitat loss and fragmentation are the principal factors underlying population decline of native species inhabiting the Cerrado, particularly those with a high demand for space, low population density, and specialized diet, such as the endangered giant anteater (Myrmecophaga tridactyla). Although the species has been studied in protected areas, we know much less about its ability to endure in disturbed landscapes. Here, we analyzed camera-trapping data to estimate a proxy of habitat use (ψ^; occupancy) and detection probabilities of the giant anteater, identifying environmental covariates influencing these parameters in landscapes with intensive agriculture and commercial forestry. We found this species using about half of the study area (model average ψ^ = 0.51, CI = 0.40–0.62), with two predictors strongly influencing habitat use: protected areas and unpaved roads. In turn, detection probability correlates positively with area of open Cerrado and negatively with area of settlements. The species is more likely to use unpaved roads inside protected areas (ψ^ = 0.90, CI = 0.47–0.75), compared to off road sites in the surrounding areas (ψ^ = 0.19, CI = 0.10–0.34). Our findings indicate that giant anteaters are dependent on nature reserves and native vegetation areas existing on private properties, whose protection is regulated by the Brazilian Native Vegetation Protection Law. Given the relative paucity of state-owned protected areas in the Brazilian Cerrado, increasing the adherence of rural owners to this law is, therefore, key for the conservation of the giant anteater. The intense use of unpaved roads might reflect travelling and/or foraging optimization, a behavioral response that, nevertheless, may compound this species’ susceptibility to suffer mortality from roadkill.
