A use of continent-wide qualitative ABBCS data on the abundance of the Ruff Philoma- chus pugnax on the breeding grounds and advanced statistical techniques led to a hypothesis of global population re- distribution in this migrant wader. This approach is pending testing on other species of Arctic-breeding birds.

Blas- tenia scabrosa is a new combination supported by molecular data. Blastenia scabrosa, Caloplaca fuscorufa and Flavoplaca havaasii are new to Russia. Blastenia scabrosa is also new to the Caucasus Mts and Sweden. Detailed morphological measurements of the Russian specimens of these species are provided. Caloplaca exsecuta, C. grimmiae and C. sorocarpa are new to the Murmansk region. The taxonomic position of C. alcarum is briefly discussed. Key words: Arctic, Rybachy Peninsula, Caloplaca s. lat., Blastenia scabrosa. Introduction Although the Murmansk region is one of the best studied regions of Russia in terms of lichen diversity, there are numerous reports in recent literature of new discoveries there (e.g. Fadeeva et al. 2013; Konoreva 2015; Melechin 2015; Urbanavichus 2015). Several localities in the northwest of the Murmansk region, mainly on the Pechenga Tundra Mountains and the Rybachy Peninsula, were visited in 2013 and 2015.

Talbot, Mikhail Telyatnikov, Dietbert Thannheiser, Patrick J. Webber & Lisa M. Wirth Abstract Aims: An Arctic Vegetation Classification (AVC) is needed to address issues related to rapid Arctic-wide changes to climate, land-use, and biodiversity. Location: The 7.1 million km2 Arctic tundra biome. Approach and conclusions: The purpose, scope and conceptual framework for an Arctic Vegetation Archive (AVA) and Classification (AVC) were developed during numerous workshops starting in 1992. The AVA and AVC are modeled after the European vegetation archive (EVA) and classification (EVC). The AVA will use Turboveg for data management. The AVC will use a Braun-Blanquet (Br.-Bl.) classification approach. There are approxi- mately 31,000 Arctic plots that could be included in the AVA. An Alaska AVA (AVA-AK, 24 datasets, 3026 plots) is a prototype for archives in other parts of the Arctic. The plan is to eventually merge data from other regions of the Arctic into a single Turboveg v3 database. We present the pros and cons of using the Br.-Bl. clas- sification approach compared to the EcoVeg (US) and Biogeoclimatic Ecological Classification (Canada) ap- proaches.

  • Finnish Botanists and Mycologists in the Arctic1
    525 ARTICLE Finnish botanists and mycologists in the Arctic1 Henry Väre Abstract: Finnish botanists and mycologists have studied Arctic areas and timberline regions since the beginning of the 18th century. Most expeditions to the Kola Peninsula were made between 1800 and 1917 and until 1945 to Lapponia petsamoënsis on the western rim of the Kola Peninsula. Since those years, these areas have been part of the Soviet Union or Russia. Svalbard and Newfoundland and Labrador have been studied repeatedly as well, Svalbard since the 1860s and Newfoundland and Labrador since the 1930s. This article focus- es on Finnish collections. These are deposited in the herbaria of Helsinki, Turku, and Oulu universities, except materials from the Nordenskiöld expeditions, which were mainly deposited in Stockholm. Concerning the Kola Peninsula, collections at Helsinki are the most extensive. The exact number of specimens is not known, but by rough estimation, the number is about 60 000, with an additional 110 000 observations included in the data- base. These expeditions have provided material to describe 305 new taxa to science, viz. 47 algae, 78 bryophytes, 25 fungi, 136 lichens, and 19 vascular plants. This number is an underestimate, as many new species have been described in several separate taxonomic arti- cles. At least 63 persons have contributed to making these collections to Finnish herbaria. Of those, 52 are of Finnish nationality. Key words: bryophytes, fungi, vascularplants, Finnish, Arctic. Résumé : Les botanistes et les mycologues finlandais ont étudié les régions arctiques et les régions de limite forestière depuis le début du 18ème siècle. La plupart des expéditions à la presqu’île de Kola ont été faites entre 1800 et 1917 et jusqu'à 1945 à Lapponia petsamoënsis For personal use only.

  • Petroleum Geology & Hydrocarbon Potential of the Yenisei-Khatanga
    A non-proprietary report by Blackbourn Geoconsulting Petroleum Geology & Hydrocarbon Potential of the Yenisei-Khatanga Trough This report covers the petroleum geology of an area of Northern Siberia north of the Central Siberian Plateau, from the Gyda Peninsula in the west to the coast of the Laptev Sea in the east, and including the Yenisei gulf/estuary, the Taimyr Peninsula and Yenisei-Khatanga Trough. The data are mostly derived from published Russian-language sources (supported by several “western” sources, which are relevant mainly to the large-scale tectonic development of the area). This study is therefore comparable in its nature and scope to other reports in Blackbourn Geoconsulting’s series on the petroleum geology of the regions of the former Soviet Union. Tectonic Development of the Region There have been numerous papers published on the tectonic development of different parts of the study area over the past decade. These have been integrated to provide an overview of the tectonic development of the area as a whole, and that of individual basins. Some Precambrian prospectivity is claimed for parts of the region, although known hydrocarbons appear to be derived exclusively from the Mesozoic and younger deposits. All maps provided in the report are georeferenced and are available in ArcGIS format. The report covers the following geographic areas: Gyda Peninsula This forms the western end of the area of study, and is also covered in Blackbourn’s regional study on “The Petroleum Geology of Western Siberia”. More detailed stratigraphic and palaeogeographic data are now available, including significant new data on hydrocarbon- source characteristics.
