New data on the status of threatened bryophytes of Madeira Island

during interglacials and that on Bermuda the present manifestation of Pireella cymbifolia, for example, is probably no older than the last glacial period. The period of time available for the differentiation of most endemic plants of Bermuda may well be less than 120 Kyr and certainly no more than 400 Kyr. These time constraints must be taken into consideration in any systematic analysis of the flora of Bermuda or the degree of genetic differentiation of any of its elements.

Epiphytic bryophyte diversity on Madeira Island: Effects of tree species on bryophyte species richness and composition

Abstract The Madeiran laurel forest (Laurisilva) is a subtropical forest with a very rich bryophyte flora and is considered as one of the most important remnants of the evergreen laurel forest from the Tertiary period. The effect of the laurel forest tree species on the epiphytic bryophyte species richness and composition in Madeira Island was studied in 40 sites. A total of 160 trees, belonging to 19 different tree species were assessed in the laurel forest. For subsequent analyses, we focused on seven tree species, for which at least nine individuals were sampled. A total of 137 trees from 40 sites were thus available for statistical analyses. We recorded 110 epiphytic bryophyte taxa (59 species and one variety of mosses and 50 liverworts). Accumulation curves showed clear differences in bryophyte species richness between the different tree species, with typical laurel forest tree species harboring more bryophytes. Tree species also had highly significant effects on species density (mean species richness per 10 × 20 cm plot), with densities higher on the typical laurel forest trees. This was especially true for the liverworts and the endemics for which Clethra arborea, Laurus novocanariensis, Ocotea foetens and Persea indica exhibited higher species density than the two Erica species and Myrica faya. For mosses species density of the tree species tended to be more similar, only O. foetens showed a higher density and M. faya a lower. Endemic bryophytes were lacking on Erica species and almost lacking on M. faya. Concerning species composition, we found significant effects of the tree species sampled. There was a rather clear gradient from the two Erica species to the typical laurel forest tree species such as L. novocanariensis, O. foetens, and P. indica. An analysis of indicator species revealed ten significant indicator species for the typical laurel forest trees, C. arborea, L. novocanariensis, O. foetens and P. indica. Our results reinforced the importance of the laurel forest of Madeira as a hotspot of epiphytic bryophyte diversity whose species distribution is strongly shaped by the nature of the tree species.

Chorological data and threat status evaluation of Fissidens species (Fissidentaceae, Bryophyta) on Madeira Archipelago

Madeira Archipelagos bryoflora includes 23 Fissidens taxa of which four are endemic to Macaronesia (Fissidens coacervatus, F. microstictus, F. nobreganus and F. sublineaefolius), including two exclusive to Madeira (F. microstictus, F. nobreganus), and several others that are considered rare or threatened in Europe. However, the distribution and threat status of several Fissidens species on Madeira Archipelago is yet insufficiently known. Based on recent field work and revision of herbarium collections, distribution data, habitat preferences, and threat status on Madeira Archipelago are updated for the Madeiran endemic F. nobreganus, the Macaronesian endemics F. coacervatus an d F. sublineaefolius, as well as five other rare or insufficiently known species, F. curvatus, F. crispus, F. dubius, F. ovatifolius and F. polyphyllus.

Molecular, phytochemical and morphological characterization of the liverwort genus Radula in Portugal (mainland, Madeira, Azores)

Relationships of the eight species of the liverwort genus Radula occurring in Portugal (mainland, the Madeira and Azores archipelagos), including the Macaronesian endemics R. jonesii and R. wichurae, were evaluated based on molecular, phytochemical and morphological–anatomical data. Maximum parsimony and Bayesian analyses were performed with sequences from three plastid DNA markers (trnS GGA-rps4 spacer, rps4 gene, trnL UAA intron), volatile oil compounds, as well as qualitative morphological–anatomical characters. In addition, the molecular data were subjected to maximum likelihood analysis. The eight taxa, R. aquilegia, R. carringtonii, R. complanata, R. holtii, R. jonesii, R. lindenbergiana, R. nudicaulis and R. wichurae, can be clearly distinguished from each other, either by molecular data alone or by combination of characters from all three data sets. Radula aquilegia is monophyletic according to the molecular data, but shows considerable, yet undescribed intraspecific morphological and phytochemical variability. Recognition of R. complanata and R. lindenbergiana as separate species, previously based solely on the paroecious vs. dioecious sexual condition, is moderately supported by the molecular phylogenetic analyses and strongly supported by the phytochemical data. The Radula species, narrowly distributed in Macaronesia and Atlantic Europe, probably have two different origins. For Radula holtii and R. nudicaulis, connections with Radula species from the Neotropics are indicated. The other species, among them the two Macaronesian endemics, are closely related with the R. complanata/R. lindenbergiana complex, which is widely distributed in the northern hemisphere.
