“…The new Russian record extends the range of O. vittii considerably eastward. Another species of Orthotrichum with hyaline leaf tips and strongly ribbed capsules, O. dagestanicum, was recently described from the southern part of the Dagestan Republic (Fedosov & Ignatova, 2010), but the specimen cited here demonstrates all the characters of O. vittii, including the possession of a long hyaline hair point (up to 350 mm, even longer than that described by Lara et al, 1999), and 16 appendiculate endostome segments. R. brunnea is oro-temperate in East Asia, sparsely distributed in Russia (Russian Far East: Sakhalin, South Kuril Islands) and Japan (Hokkaido, Honshu, Shikoku, Kyushu) (Bakalin, 2010;Konstantinova et al, 2009b;Yamada, 1979).…”

“…One of the largest genera within the family, Orthotrichum, composed of at least 162 species [31], has been updated according to a number of sources [10,[32][33][34][35][36][37][38][39][40]. Conversely, the genus Nyholmiella includes only two taxa (Nyholmiella gymnostoma and N. obtusifolia) [41].…”

Modeling the distribution of rare and interesting moss species of the family Orthotrichaceae (Bryophyta) in Tajikistan and Kyrgyzstan

Bryological research carried out from 2008 in Tajikistan and Kyrgyzstan brought interesting data on the occurrence of epiphytic bryophytes which have not been recorded yet there. One of the species was recently described as a new (Orthotrichum pamiricum) and some of the other newly recorded species are considered as rare or endangered in the region of Middle Asia. To make detailed field monitoring of the species with the aim of mapping their distribution in a wild and complex mountainous terrain, it was necessary in the first instance to identify the area with suitable conditions for the occurrence of these species. We present an innovative modeling program MaxEnt (maximum entropy modeling), which have not previously been used for modeling either epiphytic bryophytes or in the Middle Asia region. Using 205 samples (presence-only data), percent tree cover, and seven uncorrelated bioclimatic variables, regions suitable for the occurrence of the studied species were identified. Distribution models for eight most interesting species of Orthotrichum are presented here (O. affine, O. anomalum, O. crenulatum, O. cupulatum, O. pallens, O. pamiricum, O. pumilum, and O. speciosum). They indicated appropriate areas for the most probable occurrence of the species in western Tajikistan, and southwestern and northeastern Kyrgyzstan. These results could serve as guides for future survey expeditions, and aid in the conservation of target species and our understanding of their ecology. Different environmental variables for various species were selected as the most important for modeling. However, for most species higher minimum temperatures and higher precipitation in the wettest month and mean diurnal range were the variables with the greatest contribution to the models.
