Biomonitoring with cryptogams near the power station of la Robla (Leon, Spain)
The present monitoring study was undertaken to analyze the impact of atmospheric pollution on the lichens found near a power station in northern Spain. Data from 565 releves gathered on 113 sites were analyzed. In areas near the power station the lichen species belong to the Xanthorion community. In areas away from the power station and that are not under the influence of dominant winds, the lichenic diversity increases and the species present belong to the Parmelion community. In intermediate areas between the two, there is a great increase in lichen diversity, in these areas there is a replacement of the species that typically belong to the Xanthorion community, by species typical of the …
Chlorophyll a fluorescence in transplants of Parmelia sulcata Taylor near a power station (La Robla, León, Spain)
Healthy thalli of Parmelia sulcata Taylor were transplanted to 8 localities in the surroundings of a power station (La Robla, León, Spain), the sole pollution source in the region. Changes in chlorophyll a fluorescence were monitored in the transplants 12 months, 18 months and 24 months after transplantation. Statistically significant differences were observed in the ratio of variable to maximal fluorescence, non-photochemical fluorescence quenching and vitality index. The decrease in fluorescence parameters was higher in the localities of Cuadros and Rabanal de Fenar, which are situated a few kilometres away from the power station and in the same direction as the prevailing winds.
Líquenes y hongos liquenícolas de la Serranía de Ronda (Málaga-Cádiz), sur de España
As a result of a field trip organised by the Spanish Lichen Society in Serranía de Ronda, south Spain, a catalogue of 360 taxa is presented (336 lichens, 24 lichenicolous fungi). The list includes three new records for the Iberian Peninsula: Arthonia paretinaria, Micarea myriocarpa and Niesslia keissleri, 51new ones for the Autonomous Andalusian Community, and three and 81 new ones for the province of Cádiz and of Málaga, respectively. After these results, the total updated number of the province of Málaga rises to 556 lichens and lichenicolous fungi. The best represented lichen genus is Cladonia (18) with the most species, unlike Lecanora (15), Pertusaria (12), Physconia (12) and Collema (…
