Contribution to the knowledge of lycophytes and pteridophytes in the atmosphere of the Iberian Peninsula
Abstract
Vascular plants that do not form seeds are known by the common name of ferns, with about 120 species in the Iberian Peninsula, which are more abundant in humid forests and saxicolous environments. In urban and semi-urban environments they are usually not very common, a fact that seems to be linked to the low presence of their spores in the atmosphere in these areas, compared to other biological particles such as fungal spores or pollen grains. The aim of this work is to provide a key to determine the spore types of the most common lycophytes and ferns in or near urban environments, discriminating 12 genera. In addition, it is intended to facilitate their identification in aerobiological samples and thus allow a better understanding of these spore types and their urban atmospheric dynamics.
