• A New Nonparasitic Species of the Holarctic Lamprey Genus Lethenteron Creaser and Hubbs, 1922, (Petromyzonidae) from Northwestern North America with Notes on Other Species of the Same Genus

      Vladykov, Vadim D.; Kott, Edward (University of Alaska. Institute of Arctic Biology, 1978-04)
      A new nonparasitic lamprey, Lethenteron alaskense from Alaska and Northwest Territories is described and illustrated. The holotype (No. NMC 76-614) is deposited in the National Museum of Natural Sciences, Ottawa, Canada. The study was based on 67 metamorphosed specimens. The species, by its permanently non-functional intestinal tract and weak dentition, smaller disc and much smaller size (maximum 188 mm), is easily separable from the parasitic Lenthenteron japonicum (maximum length 625 mm) found in the same areas. It is distinguishable from nonparasitic L. lamottenii, found in eastern and southern North America, by 1) a generally weaker dentition but possessing more anterials and supplementary marginals; 2) typically with five velar tentacles as opposed to seven in L. lamottenii; 3) differences in pigmentation pattern of the second dorsal fin and a lack of dark pigmentation on the gular region; 4) smaller size in comparison to 299 mm maximum length in L. lamottenii; and 5) distinct areas of geographical distribution separated from each other by 2400 km. All three, L. alaskense, L. lamottenii, and L. japonicum have usually 66 to 72 trunk myomeres. L. alaskense, by its higher number of myomeres is separable from two other nonparasitic species: L. reissneri from Asia with less than 64 myomeres and L. meridionale from eastern tributaries of the Gulf of Mexico with 50 to 58 myomeres.

    • A review of Arctic grayling studies in Alaska, 1952-1982

      Armstrong, Robert H. (University of Alaska. Institute of Arctic Biology, 1986-12)
      Most information on studies of the Arctic grayling (Thymallus arcticus) in Alaska came from annual progress and performance reports of the Alaska Department of Fish and Game and reports of the Alaska Game Commission prepared before Alaska Statehood in 1959. Only a few reports have been published. Sport harvest, stocking, life history and population estimates are reviewed, and recommendations for further research are offered.
    • Some New Records and Range Extensions of Arctic Plants for Alaska

      Johnson, Albert W.; Viereck, Leslie A. (University of Alaska. Institute of Arctic Biology, 1962-09)
      Johnson, Albert W. and Leslie A. Viereck. 1962. Some new records and range extensions of arctic plants for Alaska. Biol. Pap. Univ. Alaska, No. 6. Pp. iv + 32. Many vascular plant species not previously reported from coastal northwest Alaska were found during floristic investigations in that region. Plant collections were made primarily in the Ogotoruk Creek-Cape Thompson area but extended as far as Keeseemalouk Creek on the southeast and to Cape Lewis on the northwest. This area is characterized by long, cold winters, cool summers, low precipitation, and high winds. Superimposed on substrates composed of basic to acidic rocks and their erosion products are vegetation types and plant communities, the most common of which are dominated by Dryas octopetala and sedges. The mosaic of habitats in the area includes broad wet meadows, dry fellfields, talus slopes, precipitous cliffs, gravel bars and benches, snow-beds, tundra ponds, strands, and coastal lagoons, each of which supports a characteristic aggregation of species. The 37 species presented in this paper are: Calamagrostis deschampsioides Trin., C. lapponica (Wahlenb.) Hartm., Trisetum sibiricum Rupr., Koeleria asiatica Domin., Puccinellia vaginata (Lge.)

    • Studies of Birds and Mammals in the Baird and Schwatka Mountains, Alaska

      Dean, Frederick C.; Chesemore, David L. (University of Alaska. Institute of Arctic Biology, 1974-03)
      In 1963 a joint University of Alaska-Smithsonian Institution crew worked at five locations in the Baird and Schwatka mountains in northwestern Alaska, conducting an ecological reconnaissance and faunal and floral inventory. Standard methods of observation and collection were used. Camps in the Kobuk drainage were located in the Redstone River valley and at Walker Lake, both on the margin of the taiga. The Noatak valley was represented by one camp each in the lower, middle, and upper reaches of the river, all in tundra. A summary of pre-1963 ornithological work in the region is presented. Significant records of distribution and/or breeding were obtained for the following birds: Podiceps grisegena, Anas platyrhynchos, Aythya valisineria, Histrionicus histrionicus, Melanitta perspicillata, Mergus merganser, Aphrizia virgata, Bartramia longicauda, Actitis macularia, Tringa flavipes, Phalaropus fuficarius, Lobipes lobatus, Larus hyperboreus,Xema sabini, Sayornis saya, Nuttalornis borealis, Eremophilia alpestris, Tachycineta thalassina, Riparia riparia, Petrochelidon pyrrhonota, Phylloscopus borealis, Dendroica petechia, Leucosticte tephrocotis, Zonotrichia atricapilla, Calcarius pictus; and the mammal, Spermophilus undulatus. Good series of Cletihrionomys rutilius (350) and Microtus miurus (147) have been deposited in the University of Alaska Museum. Severe doubt has been raised regarding the validity of the standard three-night trap grid for population estimation under wet conditions in arctic areas.

    • Taxonomy and Ecology of the Inconnu, Stenodus Leucichthys Nelma, in Alaska

      Alt, Kenneth T. (University of Alaska. Institute of Arctic Biology, 1969-03)
      A taxonomic and life history study of the inconnu was carried out on populations from the Kobuk, Chatanika, and upper Yukon Rivers, and Selawik, Alaska. Data on 24 morphological measurements and 11 meristic counts show little difference among: 1) males and females; 2) young and older inconnu; and 3) fish from the upper Yukon River, Chatanika River, Selawik, and Kobuk River in Alaska and the Ob River, USSR. Based on close agreement of these counts and measurements, the inconnu in Alaska is designated as Stenodus leufifhthys nelma (Pallas). For arctic fish, the inconnu exhibits a rapid growth rate. Growth rates for males and females are similar, but females live longer than males. Alaskan inconnu become sexually mature quite late in life (for Selawik males, 9 years; females, 10 years). Spawning behavior is described. Spawning occurred in the Kobuk River above Kobuk the last days of September at water temperatures betwen 1/4 and 4.6 C. Older inconnu are mainly piscivorous while the younger fish feed on invertebrates and fish. The least cisco, Coregonus sardinella, was the main food item of the Selawik inconnu. The estimated catch in Northwest Alaska in 1965 was between 34,200 and 37,000 fish, 85% of which were taken for subsistence.
    • Variations in the Skull of the Bearded Seal

      Manning, T. H. (University of Alaska. Institute of Arctic Biology, 1974-11)
      Fourteen measurements taken on 260 skulls are described and analysed using variance, covariance, reduced major axes, and discriminant functions. No sexual variation is found. Changes in relative growth with age are demonstrated and discussed. Skulls from the Atlantic adult population are shown to be significantly larger than those from the Pacific in most dimensions. An important exception, nasal breadth, is significantly smaller. Differences in the regression coefficients between the Atlantic and Pacific populations are probably not significant, but some differences in position of the regression lines are highly significant. The results are compared with those of some previous authors and the boundaries between the populations considered. The recognition of E. b. nauticus for the Pacific population is justified.
    • Vegetation in the vicinity of the Toolik Field Station, Alaska

      Walker, Donald A.; Maier, Hilmar A. (University of Alaska. Institute of Arctic Biology, 2008)
      This publication contains a group of vegetation maps at three scales in the vicinity of the Toolik Field Station. Alaska, which is an arctic research facility run by the Institute of Arctic Biology at the University of Alaska Fairbanks. The maps are intended to support research at the field station. The front side of this map sheet contains a vegetation map and ancillary maps of a 751-km squared region surrounding the upper Kuparuk River watershed, including the Toolik Lake and the lmnavait Creek research areas, as well as portions of the Dalton Highway and Trans-Alaska Pipeline from the northern end of Galbraith Lake to Slope Mountain. The reverse side shows more detailed vegetation maps of the 20-km squared research area centered on Toolik Lake and a 1.2-km squared intensive research grid on the south side of Toolik Lake (red rectangles on Map A). All the maps are part of a hierarchical geographic information system (GIS) and the Web-based Arctic Geobotanical Atlas (http:/www.arcticatlas.org/). The atlas also includes other map themes for all three areas and a previously published hierarchy of maps of the lmnavait Creek area (Walker et al. 1989: Walker and Walker 1996) (black rectangles on Map A). Photos and explanations of the geobotanical mapping units and the supporting field data and metadata can also be found on the website.
