It belongs within the Retuerta del Bullaque municipalty, in Ciudad Real province, Castilla-La Mancha, in the centre of the Toledo Mountains. This mire occupies 0.22 ha and it is not protected under any conservation plan, despite its position close to a historical cattle track. This area is under the influence of a typical Mediterranean climate, with warm and dry summers and cold and wet winters. Irregular rainfalls reach their maximum values in winter. The mean annual temperature is around 14‒15 °C, while the annual precipitation is 600‒700 mm. Vegetation surrounding the mire is typically Mediterranean: woodlands mainly composed of holm oaks (Quercus ilex L. subsp. ballota [Desf.] Samp.) and cork oaks (Q. suber L.) in the meso-Mediterranean foothills. Holm oaks are associated with meso-thermophilous taxa such as strawberry tree (Arbutus unedo L.), while cork oaks usually co-occur with deciduous trees (Q. faginea Lam. subsp. broteroi [Cout.] A.Camus, Acer monspessulanum L. or Sorbus torminalis [L.] Crantz, among others). In the supra-Mediterranean bioclimatic belt, and on north-eastern oriented slopes, it is possible to find deciduous oak woodlands, where Q. pyrenaica Willd. is the most representative taxon, along with some chestnut trees (Castanea sativa Mill.) (Perea García-Calvo et al. 2015, 2016). Riparian forests are characterized by Salix atrocinereaBrot., Salix salviifolia Brot., Frangula alnus Mill., Fraxinus angustifolia Vahl., and Betula spp. Among them, the presence of Ilex aquifolium L., Taxus baccata L. and Prunus lusitanica L. on well-drained soils is noticeable. Vegetation around the mire is composed by Sphagnum spp., Drosera rotundifolia L., Pinguicula lusitanica L., Erica tetralix L., E. lusitanica Rudolphi, Dactylorhiza elata subsp. sesquipedalis (Willd.) Soó, Genista anglica L., Lobelia urens L. andMolinia caerulea (L.) Moench. (López-Sáez et al. 2014). The bedrock is an old siliceous basement, part of the HercynianMassiff, made up of Armorican quartzites and slates (Muñoz Jiménez 1974, 1976).","PeriodicalId":50414,"journal":{"name":"Grana","volume":"62 1","pages":"146 - 148"},"PeriodicalIF":0.9,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45898581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Sabal honey henceforth) is one of 22 unifloral honeys recognised in the Yucatan Peninsula. This honey is harvested in February and March when Sabal yapa bloom but encompasses other important melliferous plants during the harvest season. A melissopalynological study of 24 honey samples from Tizimín, Yucatan (Mexico) was used to determine if Sabal honey is monofloral or multifloral, and to investigate the pollen contribution of other plants. Consequently, we determined the plant resources foraged by Apis mellifera. After analysis, 54 different pollen types were identified with the number of pollen types per honey sample ranging between nine and 21, with a mean of 14.75. Asteraceae and Fabaceae were the most diverse families and represented the highest percentage of contribution in pollen spectra. Sabal yapa pollen had a mean content of 56.9% (with a range of 45.4% to 84%). Bursera simaruba, Haematoxylum campechianum, Piscidia piscipula and Viguiera dentata were categorised as secondary pollen. Important minor pollen corresponded to Caesalpinia gaumeri, Ceiba pentandra, Pisonia aculeata, Thouinia paucidentata, and Trixis inula. Pollen composition revealed details of not only the rich native flora that accompanies Sabal yapa, but traditional human activities that occur around the apiaries. As expected, pollen of nectariferous species predominate in the samples, but also a number of nectarless species were found. Honeybees foraged mostly in trees present in remnants of primary vegetation, or at its different succession stages. Sabal honey could be labelled as monofloral.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"62 1","pages":"133 - 145"},"PeriodicalIF":0.9,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42987202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Melissopalynology analyses can be used to obtain information about botanical and geographical origin of honey sources and to verify quality. Thus, this study was conducted to determine pollen composition and diversity in commercial honey samples from three states in Nigeria to ascertain their botanical and geographical origins. Seven commercial Apis mellifera var. adansonii honey samples were collected from three phytogeographical regions in Nigeria between 2017 and 2019. The samples were analysed for pollen content and other remaining structured elements occurring in sediment obtained using a non-acetolysed methodology. A total of 29 pollen types were identified, related to 18 families, 28 genera, and two unidentified pollen types. Fabaceae had the largest number of pollen types, followed by Asteraceae, Malvaceae, Arecaceae, Euphorbiaceae and Rubiaceae. Among the pollen identified, 22 pollen types were from nectariferous plants dominated by Dalbergia, Fagara/Zanthoxylum, Hymenocardia acida, Irvingia gabonensis, Macaranga, Nauclea latifolia and Pterocarpus. Monofloral honey of Nauclea latifolia and Pterocarpus sp. were also identified. The geographical origin demonstrates Apis mellifera var. adansonii using nectariferous sources available from the rainforest, forest-savanna ecotone, and Guinea savanna in the southeast, southwest, and central Nigeria, as well as in the brushwood, secondary forest, and open grassland areas, suggesting their importance as pollinators or pollen disperser agent of native flora and cultivated species.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"62 1","pages":"116 - 132"},"PeriodicalIF":0.9,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45273908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pollen is radially symmetrical and generally isopolar with the exception of Grammosciadium macrodan ssp. nezaketiae where 65% of the grains have asymmetrical appearance. All the taxa are tricolporate. Ectoapertures are discontinuous (colpus length: 14.7 ± 0.8 and colpus width: 21.20 ± 2.28) with narrow and acute at the ends extending to the subpolar region. Endoapertures are in the mid-section of the ectoapertures, which is lolangate, prolate-spheroidal in Grammosciadium scabridum, while lalongate, ellipsoidal, oblate or suboblate in the other taxa. Pollen shape is triangular and semi-triangular in polar-view. Pollen outline in equatorial view is subrectangular-straight in G. scabridum and Caropodium platycarpum, however, those were subrectangular and slightly constricted in equatorial region in all others. Based on the P/E ratio, it is prolate in G. macrodon ssp. macrodon while it is perprolate in the other taxa. Ornamentation variation (i.e. psilate, psilate-perforate, psilate-rugulate, rugulate and rugulate-perforate) was observed around the apertural, equatorial and polar regions. This character has been found as taxonomically important for the studied taxa.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"111 ","pages":"79 - 93"},"PeriodicalIF":0.9,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41275645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their distinction is difficult and has been confused in the past. In addition, a long history of numerous recombinations with different genus names (e.g. Tsugaepollenites and Sciadopityspollenites), and inconsistent classifications or synonymisations, further complicate the taxonomic framework of Cerebropollenites thiergartii. A comprehensive study of these ten taxa, summarising their crucial distinctive characteristics and potential synonymy, is currently missing. This limits the stratigraphic value of Cerebropollenites thiergartii and associated taxa relevant to the Triassic–Jurassic transition. Here, we revisit relevant holotype material, related taxa and investigated new material for potential interspecific and intraspecific morphological variation. Based on an empirical analysis of name use and an extensive literature review, we identified previous sources of confusion, re-evaluated the distinctive characteristics and stratigraphic value of these taxa, and their relevance for the Triassic–Jurassic transition. Finally, we argue that the recombination as Sciadopityspollenites thiergartii is taxonomically and nomenclaturally imperative, not only due to priority, but also because it unifies previous disjunct use of Cerebropollenites for Mesozoic and Sciadopityspollenites for Cenozoic taxa, or Mesozoic species in many Russian studies.

Principal component analysis separated honey samples from low-altitude regions while high-altitude regions form a tight cluster. Pollen diversity was found to be lower in honeys at low altitudes and higher pollen diversity was found in honeys at high altitudes. Altitude plays an important role in the pollen content of the honey, with Cornus mas, Asteraceae, and Hypericum being indicator pollen types above 1500 m; Castanea sativa and Myosotis pollen were found predominant or secondary under 1100 m altitude. This has allowed the altitude preferences of some plants, which are important for beekeeping, to be associated with the location of the apiaries and, therefore, the composition of the honey.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"62 1","pages":"59 - 69"},"PeriodicalIF":0.9,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42496330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information on the distribution of sub-spore allergenic particles in the atmosphere is however limited. Therefore, the main aim of this study was to explore the behaviour of Alternaria aeroallergens in the atmosphere of Ankara, central Turkey. Aerobiological monitoring was carried out in the 2020 season. A Burkard volumetric spore trap was used for fungal spore collection, and a high-volume cascade impactor for allergen collection. The Alt a 1 levels in two air fractions (particulate matter (PM) > 10 µm and 10 > PM > 2.5 µm) were measured by an enzyme-linked immunosorbent assay. The seasonal spore integral (SSIn) was 1846 spore day/m3. In the same period, a total of 95.71 pg/m3 Alt a 1 concentration was recorded, of which 93% was recorded in PM>10 and 7% in PM10–2.5 air fraction. The amount of allergen per spore was 5.18 × 10−2 pg/spore/m3. The highest concentration for both spores and allergens was observed on 30 June, i.e. before the local crop harvest. Four days with highest spore levels occurred about one week after the rainfall (> 1 mm). Hot and humid weather probably contributed to the intensive development of fungi and an increase in the concentration of spores in the atmosphere. Our findings suggest that in areas with semi-arid climate, such as central Turkey, the weather conditions have a greater effect on behaviour of the distribution of Alternaria aeroallergens than agricultural practices.","PeriodicalId":50414,"journal":{"name":"Grana","volume":"62 1","pages":"48 - 58"},"PeriodicalIF":0.9,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43640613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
