    • Faunal Relationships of Birds in the Iliamna Lake Area, Alaska

      Williamson, Francis S. L.; Peyton, Leonard J. (University of Alaska. Institute of Arctic Biology, 1962-06)
      Williamson, Francis S. L. and Leonard J. Peyton. 1962. Faunal relationships of birds in the Iliamna Lake area, Alaska. Biol. Pap. Univ. Alaska, No. 5. Pp. ii + 73. The authors studied animal-borne diseases and birds in the Iliamna Lake area, Alaska, for 86 man-days in May and June of 1958 and 1959. The ornithological history, climate, physiography, and major ecological characteristics of the area are discussed. Twelve ecological formations representing the Moist Coniferous Forest, Coniferous Forest, and Tundra Biomes are distinguished on the basis of plant life-form and geologic features and are used to analyze the distribution of birds. Eighty-one species of birds were observed and included in an annotated list of 103 species. Evidence of breeding and specimen data are presented. Other evidence indicates changes in abundance and range from earlier studies. Populations of Canachites canadensis, Parus hudsonicus, Vermicora celata, Dendroica petechia, Passerella iliaca are intermediate between these species' interior and coastal races. Passerella iliaca zaboria, P. i. unalaschensis, and P. i. sinuosa all occur. Intermediates between P. i. zaboria and the two other races are apparently rare. These and other racial relationships are discussed. The Iliamna avifauna is comprised of Sitkan (5 species), Hudsonian (38 species) and Eskimoan (20 species) avifaunal elements associated with the Moist Coniferous Forest, Coniferous Forest, and Tundra Biomes respectively. Nineteen widely distributed species were valueless in detective faunal relationships. The data suggest that extreme southeastern Alaska, Prince William Sound, and probably Kodiak and Afognak Islands constitute distinct faunal districts. The Iliamna-Cook Inlet region has a mixed avifauna.
    • 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.)

      Manning, T. H. 1964. Geographical and sexual variation in the Long-tailed Jaeger, Stercorarius longicaudus Vieillot. Biol. Pap. Univ. Alaska, No. 7. Pp. iii + 16 (Author's address: RR 1, Merrickville, Ontario, Canada) Statistical comparison of the color of the underparts of 474 Nearctic and 64 western and central Palearctic sexed specimens of Long-tailed Jaegers indicates that S. l. pallescens Loppenthin is a valid race ranging across the Nearctic and eastern Siberia to the Indigirka River. Spitsbergen specimens are also referable to this race; Iceland specimens belong to S. l. longicaudus. Females are significantly darker than males. The origin and migration of the two races are discussed. bills and wings of Nearctic males are shorter than those of females, and there are significant geographical differences within the Nearctic population. Regression and correlation statistics for wing and bill lengths are given and discussed. Thirty-two weighed specimens indicate that within populations weight is correlated with wing length but not with bill length.
    • The Biology and Taxonomy of the Burbot, Lota Lota Leptura, in Interior Alaska

      Chen, Lo-Chai (University of Alaska. Institute of Arctic Biology, 1969-01)
      Based upon the high peduncle ratio, the pattern of its geographic variation, and the high vertebral and pyloric caecal numbers, the burbot in Alaska is considered subspecifically different from the southeastern North American burbot. The sub-specific name Lota lota leptura Hubbs and Schultz is accepted. A regression equation is given for back-calculating the previous lengths of the burbot at each age from the diameter of the corresponding ring of the otolith. Burbot grow slower but larger and live longer in Alaska than in many other areas. Specimens as long as 99.5 cm and as old as 24 years of age were caught. Most of the burbot in interior Alaska probably die before age 15. Male burbot have a shorter life span and grow more slowly in their later age than do females. The length and weight relationship changes seasonally and is related to the liver and gonad weights. The growths of liver and gonad are interrelated. Growth of the burbot in weight is also discussed. The reproductive habits of burbot are reviewed. In interior Alaska, the burbot mature at age 6 or 7 when the fish reach a length of 40 to 50 cm. Spawning takes place around February. A 1,230 g burbot produces abut 738,500 eggs. Summer food habits of burbot, and a point allotment method used in stomach analysis are described. The burbot eat mostly young burbot and sculpins. Young burbot eat mostly invertebrates, mainly Plecoptera. Young burbot seem to feed more intensively than do the adults.

    • 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.
    • Birds and Mammals of the Pitmegea River Region, Cape Sabine, Northwestern Alaska

      Childs, Henry Jr. (University of Alaska. Institute of Arctic Biology, 1969-05)
      The results of four summers study from 1957 to 1960 on the interrelationships and distribution of the vertebrate fauna along the Pitmegea River at Cape Sabine in northwestern Alaska are presented. The geologic background, climate, soils, vegetational types and land utilization are discussed. Five major plant communities are described and used to analyze the distribution of birds and mammals. These communities are Barrens, Upland Meadows, Wet Meadows, Marshes and Shrub Types. Ninety species of birds were recorded of which 55 species nested within the Pitmegea drainage. Twenty-three species of mammals were reported. Evidence of reproductive activity, local abundance and distribution and ecological interrelationships are presented. Particular emphasis is placed on microtine rodents and their predators. Evidence for a population irruption in the Tundra Vole (Microtus oeconomus) in 1959 is reported.

      Institute of Arctic Biology, University of Alaska Fairbanks, 1972-08-17
      Research efforts have yielded valuable data and insights about adaptive mechanisms for survival in cold-dominated environments and also will contribute to practical solutions to some of Alaska's pressing environmental problems. By gathering these projects together in one place, it is hoped that these proceedings will provide both a good summary of the progress as well as pinpoint the critical problem areas that demand further study.

    • Birds of the North Gulf Coast - Prince William Sound Region, Alaska

      Isleib, M. E.; Kessel, Brina (University of Alaska. Institute of Arctic Biology, 1973-11)
      The North Gulf Coast - Prince William Sound region of Alaska, phytographically, lies at the northern limit of the Sitka Spruce-hemlock coastal/subalpine forests of the Pacific Coast; it includes approximately 178,500 km2 and a shoreline of approximately 8,500 km. Fourteen habitats are utilized by birds: tundra; shrub thickets; hemlock-Sitka Spruce forests; bogs; mixed deciduous-spruce woodlands; marshes; lacustrine waters; fluviatile waters; cliffs, bluffs, and screes; moraines, alluvia, and barrier islands; beaches and tidal flats; rocky shores and reefs; inshore waters; and offshore waters. Two hundred nineteen species of birds have been recorded in the region, 111 of which are primarily water-related. Status, abundance, habitat, and seasonal occurrence are discussed in the annotated list of species. The geographic location and restrictive topography of the region make it a spectacular corridor for millions of migrating birds. In spring millions of Pintails, Dunlins, Western Sandpipers, and Northern Phalaropes move through the region, as do tens of thousands of Whistling Swans, Snow Geese, Knots, and Sanderlings. Fall concentrations of White-fronted Geese and Sandhill Cranes may exceed 100,000's. Species with notably large summering populations include Trumpeter Swans (several hundred breeding pairs), Bald Eagles (1,800-2,000 breeding pairs), Aleutian Terns (150-250 breeding pairs on Copper River Delta), Marbled Murrelets (probably millions), and Kittlitz's Murrelets (probably a few 100,000's). Significant range extensions reported include Yellow-billed Loons (fairly common in winter), Pink-footed and Pale-footed shearwaters, Brandt's Cormorants (breeding), Red-faced Cormorants (breeding), Steller's Eiders (winter), Bristle-thighed Curlews (migrant), Bar-tailed Godwits (migrant), Crested Auklets (winter), and northernmost wintering populations of waterfowl (Canada Geese, Gadwalls, Pintails, Green-winged Teals, American Widgeons) and shorebirds (Surfbirds, Black Trunstones, Dunlins, and Sanderlings). Some unexpected species reported include Skua, Anna's Hummingbird, Purple Marin, Yellowthroat, Common Grackle, and White-throated Sparrow.
    • 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.
    • 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.

    • Bibliography of the Fishes of the Beaufort Sea

      Pfeifer, Wilma E. (University of Alaska. Institute of Arctic Biology, 1977-07)
      This bibliography was prepared to serve as a reference base for further studies in the area, particularly as related to the impact of petroleum exploratory activities on the fish fauna. Included are all discovered references dealing with fishes of the Beaufort Sea and/or immediately adjacent regions. Streams of the arctic coast of North America have been included, since these are important to the anadromous fishes of the area. A number of Russian references containing information on the distribution, utilization, biology, etc, of Beaufort Sea species in Russian waters have also been included. Preparation of the bibliography was supported by the Bureau of Land Management through interagency agreement with the National Oceanic and Atmospheric Administration, under which a multi-year program responding to needs of petroleum development of the Alaskan continental shelf is managed by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) office. It represents the final report for Contract No. 03-5-022-56, Task Order No. 16, Research Unit No. 348, Dr. James E. Morrow, principal investigator.

    • 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.
