Central Yakutia with the unique permafrost landscapes is a rich and large territory of sites of interest for the development of “scientific tourism” for explorers, researchers or eco-natural-tourists. There are three types of scientific tourism relevant for Central Yakutia: the aim of which is scientific research; the aim of which is practical training and education of students of educational institutions; the aim of which is introducing the history of scientific research, unique natural resources, historical and cultural heritage to a wide range of people. The objects of interest of scientific tourism – landscapes of Khangalassky region – are classified according the selected types of scientific tourism using methods of secondary sources analysis and field research. -
Subject of the Russian Federation)
How to use the Atlas The Atlas has two map sections The Main Section shows the location of Russia’s intact forest landscapes. The Thematic Section shows their tree species composition in two different ways. The legend is placed at the beginning of each set of maps. If you are looking for an area near a town or village Go to the Index on page 153 and find the alphabetical list of settlements by English name. The Cyrillic name is also given along with the map page number and coordinates (latitude and longitude) where it can be found. Capitals of regions and districts (raiony) are listed along with many other settlements, but only in the vicinity of intact forest landscapes. The reader should not expect to see a city like Moscow listed. Villages that are insufficiently known or very small are not listed and appear on the map only as nameless dots. If you are looking for an administrative region Go to the Index on page 185 and find the list of administrative regions. The numbers refer to the map on the inside back cover. Having found the region on this map, the reader will know which index map to use to search further. If you are looking for the big picture Go to the overview map on page 35. This map shows all of Russia’s Intact Forest Landscapes, along with the borders and Roman numerals of the five index maps. If you are looking for a certain part of Russia Find the appropriate index map. These show the borders of the detailed maps for different parts of the country. -

Effects of Large Herbivore Grazing on Relics of the Presumed Mammoth
www.nature.com/scientificreports OPEN Efects of large herbivore grazing on relics of the presumed mammoth steppe in the extreme climate of NE‑Siberia Jennifer Reinecke1,2*, Kseniia Ashastina3,4, Frank Kienast3, Elena Troeva5 & Karsten Wesche1,2,6 The Siberian mammoth steppe ecosystem changed dramatically with the disappearance of large grazers in the Holocene. The concept of Pleistocene rewilding is based on the idea that large herbivore grazing signifcantly alters plant communities and can be employed to recreate lost ecosystems. On the other hand, modern rangeland ecology emphasizes the often overriding importance of harsh climates. We visited two rewilding projects and three rangeland regions, sampling a total of 210 vegetation relevés in steppe and surrounding vegetation (grasslands, shrublands and forests) along an extensive climatic gradient across Yakutia, Russia. We analyzed species composition, plant traits, diversity indices and vegetation productivity, using partial canonical correspondence and redundancy analysis. Macroclimate was most important for vegetation composition, and microclimate for the occurrence of extrazonal steppes. Macroclimate and soil conditions mainly determined productivity of vegetation. Bison grazing was responsible for small‑scale changes in vegetation through trampling, wallowing and debarking, thus creating more open and disturbed plant communities, soil compaction and xerophytization. However, the magnitude of efects depended on density and type of grazers as well as on interactions with climate and site conditions. Efects of bison grazing were strongest in the continental climate of Central Yakutia, and steppes were generally less afected than meadows. We conclude that contemporary grazing overall has rather limited efects on vegetation in northeastern Siberia. Current rewilding practices are still far from recreating a mammoth steppe, although large herbivores like bison can create more open and drier vegetation and increase nutrient availability in particular in the more continental Central Yakutian Plain. -
Spatial and Temporal Dynamics of Microorganisms Living Along Steep Energy Gradients and Implications for Ecology and Geologic Preservation in the Deep Biosphere
Spatial and Temporal Dynamics of Microorganisms Living Along Steep Energy Gradients and Implications for Ecology and Geologic Preservation in the Deep Biosphere Thesis by Sean William Alexander Mullin In Partial Fulfillment of the Requirements for the degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2020 (Defended 8 June 2020) ii ã 2020 Sean W. A. Mullin ORCID: 0000-0002-6225-3279 iii What is any man’s discourse to me, if I am not sensible of something in it as steady and cheery as the creak of crickets? In it the woods must be relieved against the sky. Men tire me when I am not constantly greeted and refreshed as by the flux of sparkling streams. Surely joy is the condition of life. Think of the young fry that leap in ponds, the myriads of insects ushered into being on a summer evening, the incessant note of the hyla with which the woods ring in the spring, the nonchalance of the butterfly carrying accident and change painted in a thousand hues upon its wings… —Henry David Thoreau, “Natural History of Massachusetts” iv ACKNOWLEDGEMENTS Seven years is a long time. Beyond four years, the collective memory of a university is misty and gray, and if it were a medieval map, would be marked simply, “Here be dragons.” The number of times I have been mistaken this past year for an aged staff scientist or long-suffering post-doc would be amusing if not for my deepening wrinkles serving to confirm my status as a relative dinosaur. Wrinkles aside, I can happily say that my time spent in the Orphan Lab has been one of tremendous growth and exploration. -

COOK† *Department of Biological Sciences, Idaho State University, Pocatello, ID 83209-8007, USA, †Museum of Southwestern Biology & Department of Biology, University of New Mexico, Albuquerque, NM 87131-0001, USA Abstract Phylogeographical investigations of arctic organisms provide spatial and temporal frameworks for interpreting the role of climate change on biotic diversity in high-latitude ecosystems. Phylogenetic analyses were conducted on 473 base pairs of the mitochondrial control region in 192 arctic hares (Lepus arcticus, Lepus othus, Lepus timidus) and two individual Lepus townsendii. The three arctic hare species are closely related. All L. othus indi- viduals form one well-supported clade, L. arcticus individuals form two well-supported clades, and L. timidus individuals are scattered throughout the phylogeny. Arctic hare distribution was altered dramatically following post-Pleistocene recession of continental ice sheets. We tested for genetic signatures of population expansion for hare populations now found in deglaci- ated areas. Historical demographic estimates for 12 arctic hare populations from throughout their range indicate that L. arcticus and L. othus persisted in two separate North American arctic refugia (Beringia and High Canadian Arctic) during glacial advances of the Pleistocene, while the high genetic diversity in L. timidus likely reflects multiple Eurasian refugia.

Ancient DNA Supports Southern Survival of Richardsons Collared Lemming (Dicrostonyx Richardsoni) During the Last Glacial Maximum
Molecular Ecology (2013) 22, 2540–2548 doi: 10.1111/mec.12267 Ancient DNA supports southern survival of Richardson’s collared lemming (Dicrostonyx richardsoni) during the last glacial maximum TARA L. FULTON,*1 RYAN W. NORRIS,*2 RUSSELL W. GRAHAM,† HOLMES A. SEMKEN JR‡ and BETH SHAPIRO*1 *Department of Biology, The Pennsylvania State University, University Park, PA 16802, USA, †Department of Geosciences, The Pennsylvania State University, University Park, PA 16802, USA, ‡Department of Geoscience, University of Iowa, Iowa City, IA 52242, USA Abstract Collared lemmings (genus Dicrostonyx) are circumpolar Arctic arvicoline rodents asso- ciated with tundra. However, during the last glacial maximum (LGM), Dicrostonyx lived along the southern ice margin of the Laurentide ice sheet in communities com- prising both temperate and boreal species. To better understand these communities and the fate of these southern individuals, we compare mitochondrial cytochrome b sequence data from three LGM-age Dicrostonyx fossils from south of the Laurentide ice sheet to sequences from modern Dicrostonyx sampled from across their present-day range. We test whether the Dicrostonyx populations from LGM-age continental USA became extinct at the Pleistocene–Holocene transition ~11000 years ago or, alterna- tively, if they belong to an extant species whose habitat preferences can be used to infer the palaeoclimate along the glacial margin. Our results indicate that LGM-age Dicrostonyx from Iowa and South Dakota belong to Dicrostonyx richardsoni, which currently lives in a temperate tundra environment west of Hudson Bay, Canada. This suggests a palaeoclimate south of the Laurentide ice sheet that contains elements simi- lar to the more temperate shrub tundra characteristic of extant D.
