Pollen grains in the atmosphere of Tétouan (NW of Morocco) were recorded during a 10 years/period (2008–2017) using a 7 day recording volumetric pollen trap by Burkard. Daily mean pollen concentrations of 10-day periods were summed and averaged over the study period to construct the pollen calendar. The average annual pollen integral (APIn) recorded during this period was 37,955 p*day/m³, belonging to 52 higher plant taxa (30 trees and/or shrubs and 22 herbaceous species). The maximum APIn (62,848 p*day/m³) was recorded in 2009 and the minimum (18,423 p*day/m³) in 2017. During the study period, the main pollen was registered from February to June (89%), with the highest daily mean pollen concentrations recorded in March (26.38%) and February (21.13%). The timing, intensity and length of the pollen seasons varied according to the taxa. The pollen calendar of Tétouan atmosphere reflects a great pollen diversity (37 pollen types), Pollen omnipresence throughout the year, long pollination periods and typically Mediterranean taxa: Cupressaceae, <i>Olea, Platanus and Quercus.</i> Some trees and herbaceous plants perform their anthesis in winter: Cupressaceae, <i>Fraxinus, Populus, Pinus, Mercurialis</i> and <i>Parietaria</i>. Some of them extend their pollen season until spring at the same time as other types of pollen appear typical of spring. <i>Morus</i> and <i>Pistacia</i> have a short pollen season, while <i>Cannabis sativa</i>, Amaranthaceae, <i>Olea</i>, <i>Parietaria, Plantago,</i> Poaceae, <i>Quercus, Rumex</i> and <i>U. membranacea</i> are characterized by prolonged pollen season. The pollen spectrum of Tétouan is differentiated by <i>Cannabis</i> pollen, and a longer and more intense pollination period than that detected in other Mediterranean regions. Based on these results, pollen calendar of Tétouan provides interesting and useful information to aerobiologists as well as professionals working in fields such as allergy and public health.\u0000</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"38 4","pages":"483 - 499"},"PeriodicalIF":2.0,"publicationDate":"2022-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-022-09761-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47393496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed at assessing the diversity of <i>Alternaria</i> species in airborne samples collected from closely located (7 km apart) and heterogeneous sites (rural, urban and unmanaged grassland) in Worcester and Lakeside, the UK. A secondary objective was to examine how the ITS1 subregion varies from ITS2 in <i>Alternaria</i> species diversity and composition. Airborne spores were collected using Burkard 7-day and multi-vial Cyclone samplers for the period 5 July 2016–9 October 2019. Air samples from the Cyclone were amplified using the ITS1and ITS2 subregions and sequenced using Illumina MiSeq platform whereas those from the Burkard sampler were identified and quantified using optical microscopy. Optical microscopy and eDNA revealed a high abundance of <i>Alternaria</i> in the rural, urban and unmanaged sites. ITS1 and ITS2 detected five and seven different <i>Alternaria</i> species at the three sampling sites, respectively. <i>A. dactylidicola</i>, <i>A. metachromatica</i> and <i>A. infectoria</i> were the most abundant. The rural, urban and unmanaged grassland sites had similar diversity (PERMANOVA) of the species due to similarity in land use and proximity of the sites. Overall, the study showed that heterogeneous and neighbouring sites with similar land uses can have similar <i>Alternaria</i> species. It also demonstrated that an eDNA approach can complement the classical optical microscopy method in providing more precise information on fungal species diversity in an environment for targeted management. Similar studies can be replicated for other allergenic and pathogenic fungi.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"38 4","pages":"457 - 481"},"PeriodicalIF":2.0,"publicationDate":"2022-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-022-09760-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50509021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UK operational network collects airborne pollen from 8 flowering trees, grasses and three weeds using Hirst traps and microscopic identification from urban areas. Knowledge of total pollen diversity and differences between rural and urban zones is limited. We collect environmental DNA (eDNA) from air during summer and autumn over 3 years with mini cyclones from one urban and one rural site. Data are analysed using next generation sequencing and metabarcoding. We find the most common genus, <i>Urtica</i> (57%), is also identified by the national network. The grasses <i>Lolium</i> (10%), <i>Agrostis</i> (2%) and <i>Holcus</i> (1%) are in the national network grouped at family level, while <i>Brassica</i> (2%), <i>Chenopodium</i> (1%), <i>Impatiens</i> (2%), <i>Plantago</i> (4%) and <i>Tilia</i> (7%) are not part of the UK operational network. DNA from 138 genera was identified, where 2% of the sample could not be associated with specific genera. 40% of the sample was classified better using eDNA methods at the genus level, than by optical methods. We calculate Bray–Curtis dissimilarity for the rural and urban zones and find a systematic difference in biodiversity. Overall, this shows airborne DNA reveals more information than methods based on morphological differences. The results also suggest data from sites located in large urban areas will be less representative for less populated rural areas. This presents a dilemma in balancing a network and the associated costs delivering health relevant information to the most populated areas vs. a nation-wide approach.</p></div>","PeriodicalId":7718,"journal":{"name":"Aerobiologia","volume":"38 4","pages":"591 - 596"},"PeriodicalIF":2.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10453-022-09759-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35257630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analysis would be the first of its kind for this area. We used 17 consecutive years from 2004 to 2020 and data collected by the city of Albuquerque using a Spore Trap (Burkard) volumetric air sampler in a location designed to represent a typical desert environment. The pollen studied include Juniper, Elm, Ash, Cottonwood, and Mulberry. We found a negative linear correlation with early summer temperatures of the previous year and APIn for Elm, Cottonwood, and Mulberry, and early fall temperatures for Juniper. Linear regression models developed for Elm, Cottonwood, and Mulberry used the monthly mean maximum temperature for the month of June of the prior year as the independent variable to yield a <i>R</i> squared statistic (<i>R</i>²) of 0.88, 0.91 and 0.78, respectively. For Juniper, the average monthly mean minimum temperature for the previous September and October served as the independent variable and yielded the <i>R</i>² value of 0.80. We also observed a positive trend for the annual maximum temperature over time and a negative trend for the total APIn. Summers in New Mexico are hot and dry, and they may be getting hotter and drier because of climate change.

According to the hypothesis that pollen physiology is negatively impacted by air pollutants, we expected a highly polluted area to have a high degree of pollen abortion with low amount of total protein content with accumulation of different elements because the high amount of particulate pollutants deposited on pollen should alter its physiology. We found that pollen viability at all three different locations is significantly similar, while pollen germination is significantly affected by pollution in Amravati City. The protein content in pollen and its shape is also affected. Correlation analysis reveals the interrelationship between pollen viability, germination, elements and protein content with respect to the polluted area.
