Abstract Tropical forests encompass a high diversity of plant species that depend on several pollinator bees, such as Melipona mondury. In the present study, we identified the pollen types in samples of honey, pollen (nest pots) and pollen baskets of M. mondury workers from a meliponary located in the Atlantic Forest of the state of Bahia, north-eastern Brazil. Samples of flowering plants were also collected monthly nearby the meliponary and from trails along the fragment borders. The botanic material was identified and stored as herbarium collections. The samples of honey and pollen from colonies of M. mondury were collected and prepared using the acetolysis method for palynological studies. Using the botanical inventory around the meliponary, palynological slides were prepared and pollen characterised from 43 genera and 46 species within 24 plant families. Asteraceae (23%), Fabaceae (14%), Anacardiaceae (5%), Myrtaceae (5%), and Melastomataceae (4%) were the most common and diverse families around the meliponary. A total of 44 and 54 pollen morphotypes were found in honey and pollen samples, respectively, comprising several plant families, particularly Myrtaceae (15%) and Melastomataceae (10%). The pollen baskets of workers contained 35 pollen morphotypes, with a predominance of Fabaceae-Mimosoideae (16%), Melastomataceae (13%), Sapindaceae (13%), Myrtaceae (10%) and Solanaceae (10%). The flora of the study area proved to be highly diverse and M. mondury utilises a wide variety of plants, albeit with some differences. The conservation of the Atlantic Forest fragments is essential to the maintenance of pollinators such as M. mondury to assure the functionality of local ecosystems.

Abstract Several investigations suggest that the exposure to fungal allergens during childhood may increase the risk of sensitisation in children genetically predisposed to allergy. The objective of this study was to evaluate the quality and diversity of fungal propagules in indoor air, specifically in the bedrooms of children with a family history of allergy. The indoor and outdoor air was sampled from 44 bedrooms of children with a family history of allergy during the years 2018 and 2019 in Havana, Cuba. Inside the bedrooms, the presence of humidity problems, visible fungal growth, and the quality of ventilation was examined, while the values of temperature and relative humidity were recorded. Moreover, a distribution analysis of the genera detected was carried out and the Sørensen coefficient of similarity was calculated. In addition, the relationship between the outdoor and indoor air concentrations of each residence was determined. The concentrations of fungal propagules in the indoor air of the bedrooms were between 20 and 1330 colony-forming unit (CFU)/m3. According to the analysed limit values, 18 bedrooms can be classified as having poor indoor air quality. Cladosporium, Aspergillus, Penicillium, and Curvularia were the most frequent genera of the 19 identified in the study. There was a similarity between the indoor and outdoor air mycobiota in 15.9% of the rooms. The detection of these allergenic fungal genera is an alert for children in the sampled homes, mainly for those that were classified as poor indoor air quality according to the examined standards.

The pollen profile was obtained from the floodplain of Ammer River Valley, west of Tübingen in southwestern Germany. Underground water from a Triassic limestone aquifer feeds the small modern-day Ammer River, which is a tributary of the Neckar River (Schwientek et al. 2013). The climate is humid-temperate with highest air temperatures from June to August (mean 21–24 °C) and lowest temperatures during December to February (mean −1 to 0 °C). The nature reserve Schönbuch north of the Ammer River Valley is characterised by thermophilous and drought-adapted vegetation on south-facing slopes (Arnold 1986). Pleistocene and Holocene sediments cover the Ammer River Valley consisting of brown alluvial clays, Tufa, grey clays, and fluvial and colluvial gravels on top of the Middle Triassic dolostones and mudstones (Geyer et al. 1995; Heidgen et al. 2020; Martin et al. 2020). In addition, the Ammer River Valley is partly covered by nutrient-rich loess deposits. Agriculture dominates today 71% of the land cover and oak, beech, and pine trees are covering hillslopes by ∼12% (Schwientek et al. 2013). Nearby, several archaeological sites have been investigated, such as Neolithic settlements of the Lineare Bandkeramik period (6.3–6.0 cal ka BP), excavated by Krauß et al. (2020), and the Mesolithic archaeological site ‘Rottenburg-Siebenlinden’ (c. 6 km away), which revealed human occupation from 10.1–7.8 cal ka BP (Kind 2010). Sediment description and dating Two sediment cores, X039A and X039B, (48° 31′ 44.11′′ N, 08° 57′ 47.73′′ E) were taken in continuous 2 m intervals with no overlap, with core recovery of about 82% (Heidgen et al. 2020). The palynological studies concentrated on the upper 8 m from core X039B (Table I), from which 46 samples, with pollen sums between 150 and 500 arboreal pollen grains, were analysed. Pollen taxonomy follows Beug (2004). In addition to dispersed spores and pollen grains, microcharcoals > 10 μm and non-pollen palynomorphs (NPPs) were registered as well. The software TILIA (incl. CONISS) was used for constructing the pollen diagram and to determine the local pollen assemblage zones (LPAZs) (Grimm 1992a, 1992b). The chronology of core X039B is based on 14 accelerator mass spectrometry (AMS) carbon-14 (C) dates (Table II).
花粉剖面采集于德国西南部t宾根以西的Ammer河谷漫滩。来自三叠纪石灰岩含水层的地下水为现今的Ammer河提供水源，这条河是Neckar河的一条支流(Schwientek et al. 2013)。气候属湿润温带，6月至8月气温最高(平均21-24°C)， 12月至2月气温最低(平均- 1至0°C)。阿默河谷北部的自然保护区Schönbuch的特点是在朝南的斜坡上有喜热和适应干旱的植被(Arnold 1986)。更新世和全新世沉积物覆盖了阿默尔河流域，由棕色冲积粘土、凝灰岩、灰色粘土、河流和砾石组成，覆盖在中三叠统白云岩和泥岩之上(Geyer et al. 1995;Heidgen et al. 2020;Martin et al. 2020)。此外，阿默尔河谷部分地区被营养丰富的黄土覆盖。如今，农业占据了71%的土地覆盖，橡树、山毛榉和松树覆盖了约12%的山坡(Schwientek et al. 2013)。附近的几个考古遗址已经进行了调查，例如由Krauß等人(2020年)挖掘的Lineare Bandkeramik时期的新石器时代定居点(6.3-6.0 cal ka BP)，以及中石器时代的考古遗址“Rottenburg-Siebenlinden”(约6公里)，揭示了人类在10.1-7.8 cal ka BP (Kind 2010)的活动。X039A和X039B两个沉积物岩心位于北纬48°31′44.11”，东经08°57′47.73”，连续2 m间隔，无重叠，岩心回收率约为82% (Heidgen et al. 2020)。孢粉学研究集中在X039B岩心上部8 m处(表1)，共分析了46份样品，花粉总数在150 ~ 500粒之间。花粉分类遵循Beug(2004)。除分散的孢子和花粉粒外，还观察到微炭bbb10 μm和非花粉孢粉形态(NPPs)。使用TILIA软件(包括CONISS)构建花粉图并确定局部花粉组合带(lpaz) (Grimm 1992a, 1992b)。核心X039B的年表是基于14个加速器质谱(AMS)碳-14 (C)日期(表2)。

The site of Rue des Boîteux–Rue d’Argent (BR295) (coordinates 50° 51’ N; 4° 21’ E, 17 m above sea level [a.s.l.]) is situated in the actual town centre of Brussels, at the foot of a steep slope leading from the alluvial plain of the Senne River to the Brabantian plateau.Mean annual temperature in Brussels is 10.4 °C. Mean temperature is 3.2 °C for January and 18.4 °C for July. Mean precipitation reaches 848 mm (KMI s.d.). The actual soil moisture regime of the region is Udic (soil moisture is sufficient throughout the year to meet plant requirements [USDA 1999: 97]). The soil temperature regime is Mesic. This implies that the mean annual soil temperature is 8 °C or higher and lower than 15 °C, and the difference between mean summer and mean winter soil temperatures is more than 6 °C (USDA 1999: 112). During a rescue excavation in 2014, a thick peat deposit was discovered. The top of the peat was affected by human activity and gradually transformed into an urban Dark Earth. Locally, modern construction works truncated the peat deposit. The peat deposit with total thickness of c. 2 m was sampled at three profiles by overlapping monolith blocks. The blocks were correlated stratigraphically based on their lithology (Table I) and the chronology was subsequently confirmed with absolute dates (Table II) so that a composite profile was obtained. Samples for pollen analysis (with volume 3 cm2) were taken at each 2.5 cm. Dating

Abstract Triprojectacites Mtchedlishvili, 1961 emend. Stanley 1970 is an important pollen group of the Northern Hemisphere palynofloras during the Late Cretaceous. It is featured by three, or occasionally four or five, projections at the equatorial zone of the body with colpate apertures and endexinous thickenings. This pollen group is very useful in the stratigraphic division and correlation for its high diversity, short stratigraphic interval, and rapid evolution. However, the diversity and complex morphology make the pollen difficult to describe and classify, which brought discrepancies in the understanding and application of genus and species. In the present article, we make a re-evaluation of the previously proposed genera by using an improved, clearly defined morphological terminology based on standardised measurements. Finally, eight genera are screened out to set a new classification system from the 39 genera that have been proposed in relation with Triprojectacites. A diagnostic key is compiled for the convenience of differentiating them.

Abstract Three treatments (Glucose, Sucrose, Bee Feed Syrup) were used to examine the influence of supplementary feeding on the pollen spectrum of the royal jelly produced by Apis mellifera L. colonies. Apis mellifera colonies were located in the Battalgazi and Dogansehir districts of Malatya province in Turkey. In total 255 royal jelly samples were investigated and the analysis recorded over 30 taxa. In both sites the control group heavily utilised Quercus, Verbascum, Astragalus, and Lamiaceae. The feeding treatments saw Quercus, Verbascum, and Astragalus still being used but in different proportions. The utilisation of Lamiaceae was much reduced and Echium became an important component in colonies that had supplementary feeding.

Abstract Garcinia dulcis (Roxb.) Kurz is a medicinal plant having potential as a source of medicinal ingredients, yet details of its reproductive biology, especially palynological features, remain largely unresearched. Therefore, a detailed description of pollen development and morphology, and pollenkitt production of G. dulcis, based on both light and electron microscopic analysis, was undertaken. The results showed that G. dulcis underwent sequential anther and pollen development with a high production of pollenkitt. Pollenkitt secreted from tapetum degradation was released early into the locular cavity (at the microspore tetrad stage). The occurrences of intinous protrusion (protruding oncus) at pollen aperture and the precocious pollenkitt production were suggested as adaptive features of G. dulcis to assist its biotic pollination, according to its smooth pollen surface. The results obtained provide new insights into the significant palynological traits that would provide baseline data for further research on G. dulcis.

Abstract The stingless bee Melipona quadrifasciata anthidioides is a major pollinator of the Brazilian semi-arid region (Caatinga), it is widely used in meliponiculture due to the economic value of the honey. The goals of this study were to identify the floral resources exploited by these bees in a human-modified area from Caatinga in Bahia, and to provide a pollen calendar that might be helpful to beekeepers. Pollen loads were collected monthly from each colony over a 7-month period. Twenty pollen morphotypes were identified with high frequencies of pollen types belonging to Myrtaceae, Fabaceae-Caesalpinioideae and Solanaceae. The dominant pollens were represented by Mimosa 1 and Mimosa arenosa (Fabaceae-Caesalpinioideae). The accessory types were Mimosa tenuiflora, and Psidium guajava (Myrtaceae), while Solanum 1 and Solanum 2 represented major isolated pollen types. Some morphotypes, such as those from Mimosa are common in anthropized areas, thus playing a major role in the survival of bee colonies from areas where floral resources are limited. The present result revealed that Melipona quadrifasciata anthidioides interacts with several plant species, thus highlighting the importance of conserving the regional flora. Moreover, the pollen calendar obtained is particularly useful to the management of this stingless bee in meliponary since it provides information about the plants that can be used as pollen source throughout the year. This information is also helpful for both the conservation of regional biodiversity and beekeeping in local agriculture.

Abstract Comparative pollen diversity of honey collected from northern and southern regions of Prayagraj district of Uttar Pradesh India during different honey flow periods were investigated in the present study. A total of 67 pollen types belonging to 32 plant families were recovered from 24 honey samples collected from different sampling points from the northern and the southern regions of Prayagraj district. While Brassica campestris, Dalbergia sissoo, Eucalyptus sp., Helianthus annuus, Peltophorum pterocarpum and Sesamum indicum were recorded as predominant pollen types in unifloral honey samples collected from the northern region; Ageratum conyzoides and Parthenium hysterophorus were recorded in honey samples from the southern region. Based on the findings of the present study we found identified pollen types belong to the native species as well as cultivated species (agricultural crops and trees) of Prayagraj district. This information may help the beekeeper to conserve plant resources for honey production. The pollen type diversity per honey sample from the southern region of Prayagraj district was richer as compared to the northern region. Shannon–Weaver Diversity Index and Pielou’s Evenness Index for pollen in the honey samples ranged from 1.41 to 2.56 and 0.62 to 0.88, respectively, indicating high plant heterogeneity foraged by the honeybees.
