“…The main pollen season (MPS) was described as the time during which most pollen (90%) was recorded, starting when the sum of daily means concentrations reached 5% of the total sum, up to the point when the sum reached 95% [12]. The pollination of all arboreal species initiated and peaked during springtime, with the exception of Cupressaceae that started their circulation in January (Tab.…”

Objectives. The aim of this study was to describe the aerobiological characteristics of NE Greece, identify the most prevalent taxa, define the duration of the main pollen season and correlate allergen records with meteorological parameters. Materials and method. A 7-day volumetric trap, running continuously throughout the year, was used to collect circulating pollen. Pollen taxa were characterized by standard protocols and counted as grains/m 3 . The main pollen season was deduced from these data and running means (10-day averages) were plotted against time. Correlations with climatic factors (temperature, rain, humidity, wind velocity) were assessed by single linear regression analysis. Results. In total, 11 pollen families were identified, including 6 arboreal and 5 non-arboreal taxa. The 5 most prevalent taxa were Oleaceae, Fagaceae, Poaceae, Cupressaceae and Pinaceae. Peak pollen concentrations were detected in April and May, with daily averages exceeding 410 grains/m 3 . Compositeae had the longest pollen season of 135 days and Oleaceae the shortest, extending to only 27 days. Correlations with meteorological parameters showed variable associations among different taxa, with mean temperature (p<0.001), relative humidity (p=0.015), and wind speed (p=0.042) emerging as the most significant determinants as regards total pollen counts. Conclusions. Describing the aerobiological characteristics of NE Greece enabled the identification of allergenic risks that are specific for this region. Records generated in this study can be used to alert sensitized individuals of prevailing seasonal patterns, in order to take necessary precautions against imminent exposures. The monitoring system established here can serve as a reference guide for future epidemiological research focusing on allergic asthma and rhinitis.

“…Each climatic area is characterized by particular pollination patterns and weather conditions, leading to such models being widely studied across different regions (Sánchez-Mesa et al 2002;Smith and Emberlin 2006;Rodríguez-Rajo et al 2010;Piotrowska 2012, Brighetti et al 2014. Similar studies have also been carried out in other taxa (Rodríguez-Rajo et al 2003, Kasprzyk 2009, Sabariego et al 2012, Oteros et al 2013.…”

Climate change: consequences on the pollination of grasses in Perugia (Central Italy). A 33-year-long study

Many works carried out in the last decades have shown that the pollen season for taxa flowering in winter and spring, in temperate regions, has tended to be earlier, probably due to the continuous rise in temperature. The mean annual temperature in Perugia, Central Italy, was about 0.5 °C higher in the last three decades compared with that registered from 1952 to 1981. The increase of temperature took place mainly in winter and spring, while no significant variation was recorded during the summer and autumn. This scenario shows variations in the timing and behavior of flowering of many spontaneous plants such as grasses, whose phenology is strongly influenced by air temperature. This work reports fluctuations in the airborne grass pollen presence in Perugia over a 33-year period (1982-2014), in order to study the influence of the warming registered in recent years on the behavior of pollen release of this taxon. The grass pollen season in Perugia typically lasts from the beginning of May to late July. The start dates showed a marked trend to an earlier beginning of the season (-0.4 day/year), as well as a strong correlation with the average temperatures of March and April. The peak is reached around 30th May, but the annual pollen index (API) is following a decreasing trend. The correlation between starting dates and spring temperatures could be interesting for the constitution of a forecasting model capable of predicting the presence of airborne grass pollen, helping to plan therapies for allergic people.

“…Traditional observation-based models employ a number of different methods to relate records of airborne pollen or phenological observations to one or more variables that can be measured or predicted, usually meteorological data. Examples in IJB include regression models (Laaidi et al 2003;Smith and Emberlin 2006;Sabariego et al 2012), time series models Silva-Palacios et al 2016), computational intelligence techniques (Puc 2012; Navares and Aznarte 2017) and process-based phenological models (Schaber and Badeck 2003;Kasprzyk 2009). The main drawback of such models is that they are generally specific to a particular site, although there are some exceptions (e.g.…”

“…It is important to remember, however, that this is only a small part of an extremely diverse field that is aerobiology. Some work has been conducted on fungal spores, and papers concerning relationships with meteorological data (Stephen et al 1990;GrinnGofroń and Strzelczak 2008, 2009 and long-term trends (Damialis et al 2015) have been published in IJB for some widespread and more easily identifiable fungal spore types. As for aerobiological articles, generally, most of this research has been from Europe (particularly Spain, Poland and the UK) and North America (again with most of this from the USA) (Fig.…”

Aerobiology and biometeorology are related fields. Here we provide a broad review of aerobiology articles published in the International Journal of Biometeorology (IJB) over the past 60 years. We consider how the quantity of such work has varied over this period as well as which regions and countries have been the focus of such work, and where there is a relative paucity. We then focus on a number of highlights and themes in this research, including aerobiology and climate change and aerobiological modelling and forecasting. While much of the article focusses on airborne pollen research, we also discuss the extent to which other airborne organic particles such as fungal spores and bacteria have been the focus of research published in IJB. Also considered are knowledge gaps and research needs and priorities with respect to the field of aerobiology. While the IJB has been one of the main platforms for presenting aerobiological research over recent decades, the article highlights the need for the field of aerobiology to embrace new sampling technologies such as spectral analysis and next-generation sequencing to identify and quantify airborne biological particles.
