  • Arctic National Wildlife Refuge Volume 2
    Appendix F Species List Appendix F: Species List F. Species List F.1 Lists The following list and three tables denote the bird, mammal, fish, and plant species known to occur in Arctic National Wildlife Refuge (Arctic Refuge, Refuge). F.1.1 Birds of Arctic Refuge A total of 201 bird species have been recorded on Arctic Refuge. This list describes their status and abundance. Many birds migrate outside of the Refuge in the winter, so unless otherwise noted, the information is for spring, summer, or fall. Bird names and taxonomic classification follow American Ornithologists' Union (1998). F.1.1.1 Definitions of classifications used Regions of the Refuge . Coastal Plain – The area between the coast and the Brooks Range. This area is sometimes split into coastal areas (lagoons, barrier islands, and Beaufort Sea) and inland areas (uplands near the foothills of the Brooks Range). Brooks Range – The mountains, valleys, and foothills north and south of the Continental Divide. South Side – The foothills, taiga, and boreal forest south of the Brooks Range. Status . Permanent Resident – Present throughout the year and breeds in the area. Summer Resident – Only present from May to September. Migrant – Travels through on the way to wintering or breeding areas. Breeder – Documented as a breeding species. Visitor – Present as a non-breeding species. * – Not documented. Abundance . Abundant – Very numerous in suitable habitats. Common – Very likely to be seen or heard in suitable habitats. Fairly Common – Numerous but not always present in suitable habitats. Uncommon – Occurs regularly but not always observed because of lower abundance or secretive behaviors.

  • General Ecology and Vascular Plants of the Hazencamp Area* D
    GENERAL ECOLOGY AND VASCULAR PLANTS OF THE HAZENCAMP AREA* D. B. 0. Savile General description AZEN CAMP,at 81”49’N., 71”18W., lies on a small sandy point on the H northwest shore of Lake Hazen, in northeast Ellesmere Island. Lake Hazen stands at 158 m. above sea-level, extends 78 km. ENE to WSW, and has a maximum width of 11 km. It lies at the northern edge of a plateau bounded on the south by the Victoria and Albert Mountains and on the north by the United States Range. The Garfield Range, a southern outlier of the United States Range, extends to within 4 km. of Hazen Camp. The high mountain ranges and icefields, with extensive areas over 2000 m., and smaller hills effectively protect the land about Lake Hazen from incursions of unmodified cold air, and induce a summer climate that is very exceptional for this latitude. On the other hand the lake itself is large enough to keep air temperatures adjacent to the shore appreciably below those prevailing a few kilometres away. The geologyof northeasternEllesmere Island has recently been described by Christie (1962). The lowlands at Hazen Camp are underlain by Mesozoic and Permian sediments, mainly sandstone and shale. These sediments outcrop conspicuously on Blister Hill (altitude 400 m.), 1.5 to 2.7 km. west of the camp; andon a seriesof small but steep foothills running southwest to northeast along a fault and passing 2.5 to 3 kn. northwest of the camp. These rocks weather rapidly. Consequently sand and clay in varying proportions are plentiful in the camp area.

  • Clonal Growth Forms in Arctic Plants and Their Habitat Preferences: a Study from Petuniabukta, Spitsbergen
    vol. 33, no. 4, pp. 421–442, 2012 doi: 10.2478/v10183−012−0019−y Clonal growth forms in Arctic plants and their habitat preferences: a study from Petuniabukta, Spitsbergen Jitka KLIMEŠOVÁ1, Jiří DOLEŽAL1, 2, Karel PRACH1, 2 and Jiří KOŠNAR2 1Institute of Botany, Academy of Sciences of the Czech Republic, Dukelská 135, CZ−379 82 Třeboň, Czech Republic 2Faculty of Science, University of South Bohemia, Branišovská 31, CZ−37005 České Budějovice, Czech Republic Corresponding author <[email protected]> Abstract: The ability to grow clonally is generally considered important for plants in Arctic regions but analyses of clonal characteristics are lacking for entire plant communities. To fill this gap, we assessed the clonal growth of 78 plant species in the Petuniabukta region, central Spitsbergen (Svalbard), and analyzed the clonal and other life−history traits in the re− gional flora and plant communities with respect to environmental gradients. We distin− guished five categories of clonal growth organs: perennial main roots produced by non− clonal plants, epigeogenous rhizomes, hypogeogenous rhizomes, bulbils, and stolons. Clonal growth differed among communities of the Petuniabukta region: non−clonal plants prevailed in open, early−successional communities, but clonal plants prevailed in wetlands. While the occurrence of plants with epigeogenous rhizomes was unrelated to stoniness or slope, the occurrence of plants with hypogeogenous rhizomes diminished with increasing stoniness of the substratum. Although the overall proportion of clonal plants in the flora of the Petuniabukta region was comparable to that of central Europe, the flora of the Petunia− bukta region had fewer types of clonal growth organs, a slower rate of lateral spread, and a different proportion of the two types of rhizomes.

  • Dates of First Flowers of Alpine Plants at Eagle Creek, Central Alaska
    DA TES OF FIRST FLO\VERS OF ALPINE PLANTS AT EAGLE CREEK, CENTRAL ALASKA ROBERT B. WEEDEN Alaska Department of Fish and Game, Fairbanks lNFORi\IATlON ABOUT FLOWERING DATES of species in northern North America is still very sparse. For a number of years I have spent most of the spring and summer at Eagle Creek, east-central Alaska (65° 27' N, 145 ° 22' W), studying ptarmigan (Lagopus spp.). I had a good opportunity to record flowering dates of the conspicuous plants in the area, and I did so. This report summarizes the results. The area of study, 15 square miles of hilly land in the drainages of Eagle and Ptarmigan Creeks, Banks the Steese Highway 104 to 107 miles northeast of Fairbanks. Elevations vary from 2600 to 4400 feet above sea level. The rounded ridges and hills are part of an eroded peneplain of Precambrian schist, interrupted by masses of granite, quartz diorite, and allied Mesozoic rocks. The area apparently was not glaciated in the Pleistocene. The climate is continental subarctic. Total annual precipitation averages 10-15 inches, with snow cover usually present from mid-September to mid­ May. Summer days tend to be cooler, breezier, and more showery than in the valleys of the Tanana and Yukon Rivers to the southwest and northeast. Days from mid-June to mid-August generally are frost-free, but snow flurries and light frosts sometimes occur within this period. Small stands of spruce (Picea glauca) occur on a few south-facing slopes between 2600 an 3300 feet; wood-cutting during the first 50 years of the century removed most trees from some stands, and regeneration has been slow.
