大气中的马德普拉塔市（阿根廷）进行了监测，使用三种不同的花粉陷阱-Burkard，Rotorod和Tauber-在开花季节（仲冬至春季），以比较的多样性和数量的花粉粒收集在每个陷阱。63%的类群多样性同时记录所有三个设备。三个陷阱中花粉含量最高的五种类型是悬铃木属、榆属、栎属、禾本科和白蜡属。Tauber陷阱包含最多的花粉与最大的颗粒类群，并专门捕获10种花粉类型的虫媒特征。在每个陷阱和本地/外地植物丰度的花粉量进行了比较，以阐明花粉植被关系上所使用的方法的效果。花粉总量的相关系数为正，所有对陷阱之间的显着。在Burkard陷阱中首先观察到最大峰，与温度的增加一致，但在三个陷阱中的一般模式是相似的，在早春达到最大值。从平均值相反的偏差观察到的Burkard和Tauber数据，这些偏差分别与风速和相对湿度呈负相关。本文讨论了在某些情况下，花粉记录是否可以以等效的方式使用，尽管有一些限制。
The atmosphere of Mar del Plata city (Argentina) was monitored using three different pollen traps-Burkard, Rotorod, and Tauber-during a flowering season (mid-winter to springtime) in order to compare the diversity and amounts of pollen grains collected in each trap. Sixty three percent of taxa diversity was simultaneously recorded by all three apparatuses. The five most abundant types of pollen in the three traps were Platanus, Ulmus, Quercus, Poaceae, and Fraxinus. The Tauber trap contained the most pollen from taxa with the largest grains, and exclusively trapped ten pollen types with entomophilous characteristics. The amount of pollen in each trap and local/extra-local plant abundance were compared to elucidate the effect of the method used on the pollen-vegetation relationship. The correlation coefficients for total pollen were positive and significant between all pairs of traps. The maximum peak was observed first in the Burkard trap, in agreement with an increase in temperature, but the general pattern in the three traps was similar, with a maximum in early spring. Opposite deviations from the mean value were observed for the Burkard and Tauber data; these deviations were associated negatively with wind speed and relative humidity, respectively. This paper discusses whether in some cases the pollen records could be used in an equivalent manner, although with some limitations.
