“…The preference of rich communities of cryptogamic epiphytes for edges was already documented (e.g. Barkman 1958, Hodgetts 1996, Glavich 2003). This contrasts with the situation encountered in angiosperms in the same area, where the diversity and quality of edge communities tend to be much lower as compared to that of the inner forest due to the invasion by a few weedy species (Honnay et al 2002).…”

Vanderpoorten, A., Engels, P. and Sotiaux, A. 2004. Trends in diversity and abundance of obligate epiphytic bryophytes in a highly managed landscape. Á/ Ecography 27: 567 Á/ 576.Although forest stands represent 47% of the total land area in Europe, alterations to the forest habitat through logging and plantation of exotic trees has led to significant changes in forest biocenoses. Due to their peculiar biology and life history, epiphytic bryophytes, which include a number of species of high conservation value, are especially concerned. Ordinal logit regression was used to test whether trends in diversity and abundance of obligate epiphytic bryophytes are explained by forest cover and spruce plantation and determine specific optima and degree of reliance to these factors at the landscape scale. Spruce plantations had a negative impact on both species diversity and abundance. Although large forest patches were important for a set of species exclusively or more frequently occurring under the forest cover, the abundance of a number of species previously identified as woodland bryophytes decreased or was uncorrelated with increasing forest cover. Furthermore, the species pool adapted to edge-related abiotic conditions was important. The global epiphytic diversity did consequently not decrease with decreasing forest cover at the landscape scale. If large forest patches are important for the conservation of a set of species exclusively or more frequently occurring under the forest cover, the conservation of epiphytic bryophytes thus also involves the conservation of pioneer trees in open landscapes. A series of management measures, which may help maximize the species diversity and probability of occurrence of key-species of high conservation interest, are proposed.A.

“…4C). The only exception is a dark brown coloration found only in some B. spiralifera specimens (Glavich 2003). The combination of a similar DNA profile and lack of distinct species boundaries strongly suggests that these two taxa are in fact chemical variants of a single species.…”

“…4A & B). With more extended sampling, Glavich (2003) found that these morphological traits were often good predictors for the identification of the two species, but at the same time noted the existence of intermediate forms. Overlapping characters were observed in both thallus colour (ranging from pale to brown in both species) and morphology of pseudocyphellae (variation ranging from linear to spiralling in both species, see also Fig.…”

“…This last feature especially is characteristic of all four species currently placed in Sulcaria (Brodo & Hawsksworth 1977;Brodo 1986). Likewise, the restricted occurrence of B. pseudocapillaris and B. spiralifera along the American west coast (Glavich 2003) is more characteristic of Sulcaria than of Bryoria, a genus typical of cool temperate and boreal regions.…”

“…These include B. pseudocapillaris Brodo & D. Hawksw. and B. spiralifera Brodo & D. Hawksw., both restricted to coastal California northward to Washington and Oregon, respectively (Glavich 2003;Glavich et al 2005). Brodo & Hawksworth (1977) tentatively placed these species in Bryoria, owing to their resemblance to certain species in section Implexae, while at the same time noting that their production of conspicuous long, typically depressed pseudocyphellae might equally justify their placement in Sulcaria Bystrek (see Bystrek 1971;Obermayer & Elix 2003).…”

Bryoria pseudocapillaris and B. spiralifera are currently treated as members of Bryoria section Implexae although conspicuous, long and depressed pseudocyphellae characterizing both species resemble those found in the genus Sulcaria. Both genera belong in Parmeliaceae and form an alectorioid group together with Alectoria, Gowardia and Pseudephebe. Parsimony and Bayesian analyses of ITS, partial GAPDH and partial Mcm7 sequence data were used to examine the phylogenetic position of B. pseudocapillaris and B. spiralifera, and in light of these results evaluate the generic delimitation of Bryoria and Sulcaria. A total of 110 specimens of 53 species containing representatives from alectorioid and closely related genera were included in the analyses. The results clearly show first, that both B. pseudocapillaris and B. spiralifera belong in Sulcaria rather than in Bryoria, and second, that they should be considered conspecific. Bryoria pseudocapillaris is proposed as a synonym under B. spiralifera and the name Sulcaria spiralifera comb. nov. is introduced.
