Aportación al conocimiento de los líquenes epífitos de Pinus halepensis, P. nigra, P. pinaster y P. sylvestris en la Península Ibérica

Abstract

A study about the lichenic epiphytic diversity on different pine forests in the Iberian Peninsula is presented. A total of 84 pine forests are studied (37 of Pinus nigra, 6 of P. halepensis, 17 of P. pinaster and 24 of P. sylvestris). The number of collected species is 170, 49 species on P. halepensis, 77 on P. pinaster, 79 on P. sylvestris and 123 lichens on P. nigra. Lichens on Pinus sylvestris in more continental areas were similar to the species growing in conifer forests of Northern Europe. The widespread element is the most abundant. The percentage of submediterranean- mediterranean lichen species is higher at lower latitude and altitude, whereas boreal species are most frequent at higher latitude and altitude.
