“…In their study conducted in Rothamstad in 1990 and 1991, L a c e y and M c C a r t n e y [8] located a spore trap in a field at a distance of about 20 cm from a clump of Pteridium aquilinum fronds. On some days of plant growth, they found the daily mean concentrations to be very high, since they exceeded 1.750 spores m - 3. However, an aerobiological study of bracken spores which was carried out under urban conditions of Edinburgh by C a u l t o n et al [9] over the period 1988-1997 produced results that differed significantly from the data reported by the previous authors. In this case, the spore sampler was installed at a height of 21 m above ground level at a distance of about 1.6 km from the nearest sporing stand.…”

“…Among 215 genera representing Pteridophyta, distributed mainly in the tropics and subtropics, aerobiological monitoring has identified 49, including 42 in the studies conducted in Asia [7]. In the literature, only several papers can be found which relate to the airborne spore content of Pteridophyta in Europe: in Rothamsted [8] and Edinburgh [9] (UK), in Rzeszów (Poland) [10], and in Salamanca (Spain) [11].…”

A b s t r a c tSimilarly to fungal spores and pollen grains, pteridophytic spores can cause allergies in humans. Pteridophyta spore concentrations in the air of Lublin, under the conditions of central-eastern Poland, were first studied over the period 2013-2014. The volumetric method was used in this study. The research showed that that spores of ferns belonging to the following genera: Asplenium, Athyrium, Blechnum, Botrychium, Cystopteris, Dryopteris, Matteuccia, Osmunda, Polypodium and Pteridium, occur in aeroplankton. Spores were recorded in low concentrations and they occurred in a dispersed pattern during the season. They were found to be absent on some days. Among the above-mentioned genera, Dryopteris and Athyrium showed the highest content of spores in aerosol. In both years of the study (2013 and 2014), similar annual spore counts were recorded, respectively 69 and 63. The most spores were identified in August.

“…Their dust-like spores have been found in the jet streams (e.g., Caulton et al 2000), and are capable of surviving intense UV radiation and low temperatures in the upper atmosphere (Gradstein and Van Zanten 1999). As a result, ferns are often among the first plants to colonize new habitats, often repeatedly (Ranker et al 1994), and are overrepresented in island floras (Kessler 2010; Ranker and Geiger 2008).…”

High gene flow in epiphytic ferns despite habitat loss and fragmentation

2011

Tropical montane forests suffer from increasing fragmentation and replacement by other types of land-use such as coffee plantations. These processes are known to affect gene flow and genetic structure of plant populations. Epiphytes are particularly vulnerable because they depend on their supporting trees for their entire life-cycle. We compared population genetic structure and genetic diversity derived from AFLP markers of two epiphytic fern species differing in their ability to colonize secondary habitats. One species, Pleopeltis crassinervata, is a successful colonizer of shade trees and isolated trees whereas the other species, Polypodium rhodopleuron, is restricted to forests with anthropogenic separation leading to significant isolation between populations. By far most genetic variation was distributed within rather than among populations in both species, and a genetic admixture analysis did not reveal any clustering. Gene flow exceeded by far the benchmark of one migrant per generation to prevent genetic divergence between populations in both species. Though populations are threatened by habitat loss, long-distance dispersal is likely to support gene flow even between distant populations, which efficiently delays genetic isolation. Consequently, populations may rather be threatened by ecological consequences of habitat loss and fragmentation.

“…La elección de los tipos esporales más relevantes en la península Ibérica se ha realizado teniendo en cuenta su distribución y abundancia (Castroviejo et al 1986; Salvo Tierra 1990) en las diferentes áreas de España y Portugal, así como los ambientes que ocupan, descartando aquellos géneros que prosperan en hábitats muy específicos como gleras de media o alta montaña o incluso en emplazamientos con unas condiciones climáticas escasamente representadas en ambos países. De igual forma se ha revisado la literatura aerobiológica acerca de esporas de plantas vasculares sin semilla en la península ibérica (Leitão et al 1996;Rodríguez de la Cruz et al 2009, 2020) y en el resto de Europa (Caulton et al 2000;Kasprzyk 2004;Haratym et al 2014;Newson et al 2000;Nilsson & Praglowski 1974), dado que el norte del área peninsular comparte bioclima con gran parte del continente europeo (Rivas-Martínez & Rivas-Sáenz, 2020). Para la clasificación y nomenclatura de los diferentes taxones se ha seguido a Gabriel y , mientras que para la terminología relativa a la morfología de esporas se ha tenido en cuenta las recomendaciones de glosarios internacionales (Lellinger & Taylor 1997;Punt et al 2007) y adaptados al español (Sáenz Laín 2004).…”

Contribución al conocimiento de las esporas de licófitos y pteridófitos en la atmósfera de la península Ibérica

et al. 2021

View full text Add to dashboard Cite

Las plantas vasculares que no forman semillas son conocidas con el nombre vulgar de helechos, presentando unas 120 especies en la península ibérica, más abundantes en ambientes forestales húmedos y saxícolas. En entornos urbanos y semiurbanos no suelen ser muy numerosos, un hecho que parece estar unido a la escasa presencia de sus esporas en la atmósfera de estas zonas, en comparación con otras partículas biológicas como las esporas fúngicas o los granos de polen. El objetivo de este trabajo es proporcionar una clave de determinación de los tipos de esporas de licófitos y helechos más comunes en los entornos urbanos o sus proximidades, discriminando para ello 12 géneros. Se pretende así facilitar su identificación en muestras aerobiológicas y permitir, con ello, un mayor conocimiento de estos tipos esporales y sus dinámicas atmosféricas urbanas.
