Сontribution to the hepatic flora of the Republic of Dagestan (Eastern Caucasus, Russia)

Abstract

An annotated list of hepatics for the Republic of Dagestan records 35 species based on approximately 150 specimens collected mainly by the author. Eight species (Chiloscyphus pallescens, Cololejeunea calcarea, Frullania jackii, Lophocolea bidentata, Ptilidium ciliare, Scapania praetervisa, Solenostoma confertissimum, Tritomaria quinquedentata) are new records for Dagestan and one taxon (Reboulia hemisphaerica subsp. australis) is new to Russia and the Caucasus. New localities for three red-listed European species (Frullania inflata, F. parvistipula, F. riparia) also are documented. These records expand our knowledge of hepatic distributions in Dagestan and the Caucasus. РезюмеПриводится аннотированный список печеночников, собранных преиму-щественно автором в Цудахарском, Чародинском и Гунибском районах Даге-стана в ходе кратковременной поездки. Восемь видов (Chiloscyphus pallescens, Cololejeunea calcarea, Frullania jackii, Lophocolea bidentata, Ptilidium ciliare, Scapania praetervisa, Solenostoma confertissimum, Tritomaria quinquedentata) указываются впервые для Дагестана, один таксон (Reboulia hemisphaerica subsp. australis) является новым для России и Кавказа. Расширено представление о распространении большинства видов, приводящихся ранее для Дагестана из единичных точек. Выявлены новые местонахождения 3 видов (Frullania inflata, F. parvistipula, F. riparia) из числа включенных в Красную книгу Европы.

“…Since that time many papers have appeared, widening its range through the Caucasus and some other areas. C. salebrosum is known from several sites in the Russian part of the mountains (Borovichev et al, 2009;Konstantinova et al, 2009aKonstantinova et al, , 2009aKonstantinova, 2011) and its discovery in neighbouring Georgia was to be expected. The hepatic flora of the Adjara is fairly well known (Bakalin et al, 2013) Didymodon nicholsonii was recorded for the first time in Serbia, in Central Serbia in the Ibar valley gorge between the towns of Ušće and Maglić.…”

Russian Caucasus distribution of fourteen hepatics rare and threatened in Europe

“…a.s.l., ## K609-5, -9, -11-05. The species was also found in one locality in the Republic of Kabardino-Balkariya (Konstantinova et al 2009b) and several localities in the Republic of Dagestan (Abramov & Abachev 1968;Konstantinova 2011). In the western and northwestern Caucasus it apparently is not rare and sometimes even abundant, especially near waterfalls.…”

“…4), was first recorded from one locality in the Republic of Dagestan on the Gunib Plateau (Potemkin et al 2010). Later Konstantinova (2011) collected it there as well, and also found it in hornbeam wood near the town of Tsudakhar (Inner Mountainous Dagestan) where it is rather common. This hepatic is a predominantly Asiatic-North American species and probably is not rare in Siberia and the Far East (e.g., Konstantinova et al 2009b;Bakalin 2010;Mamontov et al 2011).…”

“…13 (Ellis et al, 2014b). The subspecies has a disjunctive distribution; it has also been reported from eastern North America, New Zealand (Schuster, 1985), southern Europe (Schuster, 1992), northern Europe (Damsholt, 2002) and the Caucasus (Konstantinova, 2011 Riccia atromarginata is here newly recorded for the bryoflora of the Cape Verde Archipelago which expands its latitudinal range to almost 14u u N. In Europe, it is widely distributed in the Mediterranean area (Jovet-Ast, 1986;Bischler, 2004), but not in sub-Saharan Africa, while only R. atromarginata var. jovet-astiae Rauh & Buchloh is reported from Madagascar and Socotra (Kü rschner, 2000).…”
