CORTICOLOUS BRYOPHYTES OF QUERCUS-PYRENAICA FORESTS FROM GREDOS MOUNTAINS (SPAIN) - VERTICAL-DISTRIBUTION AND AFFINITY FOR EPIPHYTIC HABITATS [link]Paper  abstract   bibtex   
Epiphytic vegetation in Mediterranean deciduous woods of Quercus pyrenaica Willd. is characterized by the occurrence of a high number of facultatively epiphytic bryophytes, many of them not or rarely found on bark in other climatic areas. Based on local occurrence on different substrata, bryophyte species are grouped for their affinity for bark, and the vertical distribution of these groups is qualitatively analyzed in order to describe the ecological behaviour of bryophyte species in relation to epiphytic habitats and ecological conditions of the different tree levels. The lower tree base (0-50 cm) has the greatest bryophyte richness, and is the tree zone with the highest number of strict epiphytes, although these represent sent a small percentage in relation to the facultative ones. Reasons for this richness may be the relative attenuation of the hydric stress and the existence of a high humidity microgradient in the lower zones of the tree base (first 50 cm). The upper base (50-100 cm) is floristically similar to the trunk (100-300 cm), and both zones show a predominance of strict epiphytes and cortico-saxicolous species (including preferentially saxicolous ones, such as Grimmia spp. and Hedwigia ciliata). In these Mediterranean oak woods, ecological conditions of these two strata are likely similar to those of siliceous sunny rocks of the same area. The highest tree zones (\textgreater300 cm, crown s.l.) are dominated by strict epiphytes and cortico-saxicolous preferentially corticolous species, and form the most restrictive and xeric habitats.
