Liverworts of Putorana Plateau (East Siberia): an updated checklist

Abstract

The new checklist of Putorana liverworts was compiled based on examination of recent collections and summarizing of literature data. It includes 118 species, 47 of them are new for the plateau. The most interesting records are Odontoschisma francisci, Saccobasis polymorpha, Endogemma caespiticia and Marchantia romanica. The occurrence of 26 taxa mentioned in the literature was not re-confirmed. In general terms, the flora is typical for continental Hemiarctic with very limited number of taxa showing East Asian (Apotreubia nana) and amphi-oceanic (Cordaea flotoviana, Lophozia savicziae, Odontoschisma francisci, Saccobasis polymorpha) distribution. РезюмеСоставлен новый аннотированный список печеночников плато Путорана, основанный как на недавних коллекциях, так и на обобщении литературных данных. Список включает 118 видов, в том числе 47 приводятся для плато впервые. Наиболее интересными находками являются Odontoschisma francisci, Saccobasis polymorpha, Endogemma caespiticia и Marchantia romanica. Распространение 26 видов, указанных в литературе, не подтверждено, и часть из них могла быть приведена на основании ошибочных определений. В общих чертах флора типична для континентальной Гипоарктики с ограниченным количеством видов, показыва-ющих восточноазиатские (Apotreubia nana) или амфиокеанические (Cordaea flotoviana, Lophozia savicziae, Odontoschisma francisci, Saccobasis polymorpha) связи гепатикофлоры.

Changes of Soil Properties along the Altitudinal Gradients in Subarctic Mountain Landscapes of Putorana Plateau, Central Siberia

“…The erosion of edges of these layers resulted in alternation of flat terracelike surfaces and steep rocky slopes featuring trappean structure of slopes with several levels. For the western part of the plateau, deep narrow lake depressions of tectonic origin with steep rocky slopes are typical [15].…”

“…The Putorana Plateau, which is situated in the NW part of the Central Siberian Tableland, belongs to the regions sensitive to shifts in atmospheric circulation [15,16]. It represents a unique territory with a set of subarctic and arctic ecosystems in an isolated mountain range.…”

Interrelationships among mountain relief, surface organic layer, soil organic carbon, and its mineral association under subarctic forest tundra

“…Therefore, the presented research focused on the SOC concentration and its association with important biophysical factors and soil weathering products on extended, variably steep slopes of the vast and remote Putorana Plateau, one of the least investigated subarctic areas. The basaltic plateau encompasses approximately 250,000 km 2 in the NW part of the Central Siberian Tableland 22 . Spatial correlation between SOC and Fe and Al oxide and hydroxide concentrations identified in an adjacent section of the Yenisei River basin 23 showed that secondary Fe and Al minerals could promote SOC stabilization in the adjacent Putorana massif itself.…”

How many taxa are in the genus Aaccobasis h. Buch? Evidence from integrative taxonomy

“…In Asia the species is not rare in mountains in oceanic and suboceanic areas of Far East of Russia, particularly in Chukotka Autonomous Areas and Kamchatka Territory (Konstantinova et al, 2009;Bakalin, 2010) and occurs scattered in humid areas of mountains of South (Váňa & Ignatov 1995;Konstantinova et al, 2003) and Baikal Siberia (authors' unpublished data, see specimens examined), where it probably is not rare in appropriate localities. In the north of Asia the species is found in single localities on eastern slopes of Urals (Storozheva, 1986, Konstantinova & Lapshina, 2017, on Putorana Plateau (Bakalin et al, 2016) and several localities in the Taimyr Peninsula (KPABG, isling.org/hepatics). The species is probably more widespread in poorly studied northern and mountain regions of Asia and will be found more to be common in future studies.…”
