Abstract

Abstract This study focuses on the pollen season timing and intensity, and the influence of weather conditions, on airborne Cupressaceae, Quercus, and Poaceae pollen in two different biogeographical areas, Córdoba (Spain) and Tulsa, Oklahoma (USA), during 2010–2014. Pollen concentrations were recorded using Hirst-type spore traps. The meteorological parameters studied included temperature, relative humidity, wind speed, and rainfall. This study aims to define the pollen seasons and their intensity and relationships with meteorological parameters in different biogeographical areas. The main pollen season (MPS) of each pollen type was divided into two periods: pre-peak and post-peak. The Shapiro–Wilk normality test was applied to the pollen concentrations and log transformed data were used. Pearson correlations and linear regression were applied for the pre-peak, post-peak, and MPS for comparing pollen concentrations with meteorological parameters considering both the same day and the previous day. Then, multiple regression analysis was applied with all the meteorological parameters that showed significant results in the linear regression. The models were validated through correlations between the measured and predicted pollen concentrations. The results showed a small difference in the MPS for the different pollen types at each site. Temperature, relative humidity, and rainfall influenced the pollen concentrations. The same day's meteorological parameters usually had a greater impact on the pollen concentration than the previous day's meteorological parameters; although, pollen concentrations for the next day could be forecasted considering the meteorological parameters forecasted for the present day. The pollen concentrations showed greater correlations with temperature.

俄克拉荷马州塔尔萨市与西班牙Córdoba市柏科、栎科和禾科空气中花粉的比较

摘要本研究的重点是2010-2014年期间，在科尔多瓦（西班牙）和俄克拉荷马州塔尔萨（美国）这两个不同的生物地理区域，花粉季节的时间和强度，以及天气条件对空气传播的柏科、栎科和蒲科花粉的影响。使用赫斯特型孢子捕捉器记录花粉浓度。研究的气象参数包括温度、相对湿度、风速和降雨量。本研究旨在确定不同生物地理区域的花粉季节及其强度以及与气象参数的关系。每个花粉类型的主花粉季节（MPS）分为两个时期：高峰前和高峰后。将Shapiro–Wilk正态性检验应用于花粉浓度，并使用对数转换数据。将Pearson相关性和线性回归应用于峰前、峰后和MPS，以将花粉浓度与当天和前一天的气象参数进行比较。然后，对所有气象参数进行多元回归分析，线性回归结果显著。通过测量的花粉浓度和预测的花粉浓度之间的相关性对模型进行了验证。结果表明，每个地点不同花粉类型的MPS差异较小。温度、相对湿度和降雨量影响花粉浓度。当天的气象参数通常比前一天的气象参数对花粉浓度的影响更大；然而，考虑到当天预测的气象参数，可以预测第二天的花粉浓度。花粉浓度与温度的相关性较大。

期刊介绍： Grana is an international journal of palynology and aerobiology. It is published under the auspices of the Scandinavian Palynological Collegium (CPS) in affiliation with the International Association for Aerobiology (IAA). Grana publishes original papers, mainly on ontogony (morphology, and ultrastructure of pollen grains and spores of Eucaryota and their importance for plant taxonomy, ecology, phytogeography, paleobotany, etc.) and aerobiology. All submitted manuscripts are subject to initial appraisal by the Editors, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
