Studies of dispersal into, and speciation within, the Arctic are important to obtain better knowledge of the source areas for arctic biodiversity. Unraveling the history of recently diverged lineages such as those typical for the young arctic biome is challenging, because it is difficult to find molecular markers with sufficient variation and to handle the problem of incomplete lineage sorting and hybridization. Thus several different molecular marker systems for many potentially suitable model groups were tested and developed. Three genera which are represented in Beringia (the Asian and American land masses surrounding the Bering Strait from Lena River to Mackenzie River) and which have assumed phylogenetic connections to plants living in East Asia and North America were selected. Two of these genera are also good candidates for studying polyploidization as a mode of speciation in the Arctic, as they show large variation in chromosome number within and among the species. This study was also intended to contribute to the PanArctic Flora project by providing data to help resolving the taxonomy of some challenging species complexes. - The history of the genus Smelowskia was reconstructed based on microsatellite loci combined with sequences of nuclear and plastid regions. An Asian origin of the genus and two independent dispersal events into the Beringian and North American regions were inferred. We also found evidence for merging the Beringian S. porsildii, S. spathulatifolia, and S. jurtzevii into one species; S. porsildii. - The biogeography and phylogeny of the large genus Cardamine were inferred based on nuclear and plastid sequences. The phylogenetic trees showed limited resolutions, supporting a hypothesis of recent and rapid speciation in the genus. We found evidence for several extremely long-distant dispersal events. Dispersal into the Southern Hemisphere and the Arctic has occurred repeatedly, and we identified at least three phylogenetically distinct arctic lineages. Polyploidization has occurred independently many times during the evolution of Cardamine. Rapid divergence combined with widespread polyploidization offer an explanation for the complex evolutionary history of the genus. Two species complexes within this genus were selected for more detailed studies. 2 - Six microsatellite loci originally developed for the Arabidopsis genome, were used to identify evolutionary and taxonomic units within the Beringian Cardamine digitata aggregate. Molecular groups corresponding to morphological differences suggested recognition of four species in this complex; C. blaisdellii, C. digitata, C. microphylla, and C. purpurea. Each species included at least two ploidy levels, indicating recurrent polyploidizations. - As a first step towards addressing the origin of the circumarctic Cardamine bellidifolia, we conducted a study with main focus on its two putatively most closely related European alpine species (C. alpina and C. resedifolia) using AFLPs. Surprisingly, the arctic species C. bellidifolia was distinctly differentiated from its putative alpine ancestral lineages. Contrasting phylogeographies were inferred between the two alpine species C. alpina and C. resedifolia. A high degree of genetic distinction was found between the Alpine and Pyreneean populations of C. alpina. In addition, a high level of diversity was found within Pyreneean populations compared to Alpine populations. In contrast, C. resedifolia showed more genetic variation among populations in the Alps than between the Alps and distant areas such as Corsica, the Carpatians and the Pyrenees. These results show that the two species have very different histories of glacial survival and recolonization. - To facilitate these and future studies of recently diverged taxa, we developed 72 new microsatellite loci and tested 15 previously published loci for the Brassicaceae. We found them to provide variation among and within three distantly related genera: Cardamine, Smelowskia, and Draba. Of these 87 loci, 18 were variable within Cardamine, while ten were variable within Smelowskia. Seventy-one of these primers were variable within Draba, and 50 were variable within Draba nivalis. The markers amplifying across these genera are potentially suitable for studying other genera in Brassicaceae as well. - A phylogeographic analysis of Cassiope tetragona including both Central Asian and Beringian relatives revealed that the circumpolar ssp. tetragona was well separated from the North American ssp. saximontana. A Beringian origin of C. tetragona ssp. tetragona was inferred, and the levels and geographical patterns of differentiation and gene diversity suggested that the latest expansion from Beringia into the Circumarctic was recent, possibly during the current interglacial. The results were in accordance with a recent leading-edge mode of colonization, particularly towards the east throughout Canada/Greenland and across the North Atlantic into Scandinavia and Svalbard. 3 Sammendrag Få detaljerte studier av spredning til og artsdannelse innen arktis er gjort. Slektskap og biogeografiske mønstre må analyseres for å forstå hvordan spredning og evolusjon foregår innen det arktiske området, og for å finne opphavet til den arktiske biodiversiteten. Å finne de evolusjonære historiene i arktis er utfordrende siden det ofte er lite variasjon i vanlige molekylære markører, og hybridiseringer og ufullstendig lineage sorting skaper ytterligere problemer. Flere ulike molekylære markørsystemer for mange potensielt passende modellgrupper ble derfor testet og utviklet. I dette studiet er det valgt ut tre planteslekter som alle har utbredelse i Beringia i tillegg til andre deler av Øst-Asia og Nord-Amerika. To av de valgte slektene har stor variasjon i kromosomtall innen og mellom arter og

This paper sheds light on the sorts of population-dynamics-related differences that have emerged in the region and how these differences relate to the use of natural resources and the ethnic composition of the population. Through this study, it was shown that changes have tended to be small in local areas where indigenous peoples who have engaged in traditional natural resource use for a large proportion of the population, while changes have been relatively large in areas where the proportion of non-indigenous people is high and the mining industry has developed.

    Northern Sea Route Cargo Flows and Infrastructure – Present State and Future Potential By Claes Lykke Ragner FNI Report 13/2000 FRIDTJOF NANSENS INSTITUTT THE FRIDTJOF NANSEN INSTITUTE Tittel/Title Sider/Pages Northern Sea Route Cargo Flows and Infrastructure – Present 124 State and Future Potential Publikasjonstype/Publication Type Nummer/Number FNI Report 13/2000 Forfatter(e)/Author(s) ISBN Claes Lykke Ragner 82-7613-400-9 Program/Programme ISSN 0801-2431 Prosjekt/Project Sammendrag/Abstract The report assesses the Northern Sea Route’s commercial potential and economic importance, both as a transit route between Europe and Asia, and as an export route for oil, gas and other natural resources in the Russian Arctic. First, it conducts a survey of past and present Northern Sea Route (NSR) cargo flows. Then follow discussions of the route’s commercial potential as a transit route, as well as of its economic importance and relevance for each of the Russian Arctic regions. These discussions are summarized by estimates of what types and volumes of NSR cargoes that can realistically be expected in the period 2000-2015. This is then followed by a survey of the status quo of the NSR infrastructure (above all the ice-breakers, ice-class cargo vessels and ports), with estimates of its future capacity. Based on the estimated future NSR cargo potential, future NSR infrastructure requirements are calculated and compared with the estimated capacity in order to identify the main, future infrastructure bottlenecks for NSR operations. The information presented in the report is mainly compiled from data and research results that were published through the International Northern Sea Route Programme (INSROP) 1993-99, but considerable updates have been made using recent information, statistics and analyses from various sources.

The purpose of this work is to assess the main parameters of the Chukotka and Kolyma glaciers (small forms of glaciation, SFG): their size and volume, and changes therein over time. The point as to whether these SFG can be considered glaciers or are in transition into, for example, rock glaciers is also presented. SFG areas were defined from the early 1980s (data from the catalogue of the glaciers compiled by R.V. Sedov) to 2005, and up to 2017: these data were retrieved from sat- Key words: ellite images. The maximum of the SGF reduction occurred in the Chantalsky Range, Iskaten Range, Chukotka Peninsula, and in the northern part of Chukotka Peninsula. The smallest retreat by this time relates to the gla- Kolyma Highlands, ciers of the southern part of the peninsula. Glacier volumes are determined by the formula of S.A. satellite image, Nikitin for corrie glaciers, based on in-situ volume measurements, and by our own method: the av- climate change, erage glacier thickness is calculated from isogypsum patterns, constructed using DEMs of individu- glacier reduction, al glaciers based on images taken from a drone during field work, and using ArcticDEM for others.

  • Outline of Angiosperm Phylogeny
    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page.

In order to facilitate the assessment of biodiversity, considerable efforts have been made towards identifying surrogates because the efficient evaluation of regional biodiversity would help in designating important areas for nature conservation at larger spatial scales. However, we know little about the fundamental relationships among the three levels of biodiversity, which impedes the formulation of a general, widely applicable concept of biodiversity conservation through surrogates.

Flowering phenology and anthophilous insect communities on 64 plant species of 35 families were studied in the marsh in 1994-95. A total of 936 individuals of 215 species in eight orders of Insecta were collected on flowers from mid April to mid October, The anthophilous insect community was characterized by dominance of Diptera (58 9e of individuals) and relative paucity of Hymenoptera (26 9o), Hemiptera (6 9e), Lepidoptera (5 9e), and Coleoptera (5 9o), Syrphidae was the most abundant family and probably the most important pollination agents. Bee community was characterized by dominance of an aboveground nesting bee genus, Hylaeus (Colletidae), the most abundant species of which was a minute, rare little-recorded species. Cluster analysis on fiower-visiting insect spectra grouped 64 plant species into seven clusters, which were respectively characterized by dominance of small or large bees (18 spp.), syrphid fiies (13 spp.), Calyptrate and other flies (11 spp.), wasps and middle-sized bees (8 spp.), Lepidoptera (2 spp.), Coleoptera (1 sp.) and a mixture of these various insects (11 spp.).

The species has a disjunct but widespread range throughout North America, with eastern and western segregates separated by the Great Plains. In the east, it ranges from Nova Scotia south to Louisiana and west to Minnesota and Missouri. In the west, it ranges from British Columbia to California, east to Utah and Colorado. Although regarded as Globally Secure (G5), national ranks of N? in Canada and the United States indicate some uncertainly about its true conservation status in North America. It is listed as rare (S1 or S2) in 20% of the states and provinces in which it occurs. Floerkea is known from only 11 sites total in New England: three historic sites in Vermont (where it is ranked SH), one historic population in Massachusetts (where it is ranked SX), and four extant and three historic localities in Connecticut (where it is ranked S1, Endangered). The Flora Conservanda: New England ranks it as a Division 2 (Regionally Rare) taxon. Floerkea inhabits open or forested floodplains, riverside seeps, and limestone cliffs in New England, and more generally moist alluvial soils, mesic forests, springy woods, and streamside meadows throughout its range.

Sequence data from the nuclear internal transcribed spacer (ITS) were used to infer phylogenetic relationships within a morphologically, karyologically, and geographically well-defined group of species of Campanula (Campanulaceae), the Isophylla group. Although belonging to the same clade within the highly paraphyletic Campanula, the Rapunculus clade, members of the Isophylla group do not form a monophyletic group but fall into three separate clades: (i) C. elatines and C. elatinoides in the Alps; (ii) C. fragilis s.l. and C. isophylla with an amphi-Tyrrhenian distribution; and (iii) the garganica clade with an amphi-Adriatic distribution, comprised of C. fenestrellata s.l., C. garganica s.l., C. portenschlagiana, C. poscharskyana, and C. reatina.

The focal species of this study, Cardamine barbaraeoides, is a narrow Greek endemic that has been confused taxonomically since its original description. Based on a detailed multivariate morphometric study, we provide here a set of morphological characters that enables the reliable identification of this species. In addition, we present an identification key to C. barbaraeoides and related taxa. We have revised herbarium specimens and literature data on the occurrence of this species in Greece and ascertained that it occurs only in the Pindos mountains (the Southern Pindos and partly the Northern Pindos floristic regions).
