Design of ecoregional monitoring in conservation areas of high-latitude ecosystems under contemporary climate change
Land ownership in Alaska includes a mosaic of federally managed units. Within its agency’s context, each unit has its own management strategy, authority, and resources of conservation concern, many of which are migratory animals. Though some units are geographically isolated, many are nevertheless linked by paths of abiotic and biotic flows...
Beever, Erik A.; Woodward, Andrea Egg size matching by an intraspecific brood parasite
Avian brood parasitism provides an ideal system with which to understand animal recognition and its affect on fitness. This phenomenon of laying eggs in the nests of other individuals has classically been framed from the perspective of interspecific brood parasitism and host recognition of parasitic eggs. Few examples exist of strategies adopted...
Lemons, Patrick R.; Sedinger, James S. Fire, grazing history, lichen abundance, and winter distribution of caribou in Alaska's taiga
In the early 1990s the Nelchina Caribou (Rangifer tarandus) Herd (NCH) began a dramatic shift to its current winter range, migrating at least an additional 100 km beyond its historic range. We evaluated the impacts of fire and grazing history on lichen abundance and subsequent use and distribution by the NCH. Historic (prior to 1990) and current (...
Collins, William B.; Dale, Bruce W.; Adams, Layne G.; McElwain, Darien E.; Joly, Kyle Hydrogeomorphic processes of thermokarst lakes with grounded-ice and floating-ice regimes on the Arctic coastal plain, Alaska
Thermokarst lakes cover > 20% of the landscape throughout much of the Alaskan Arctic Coastal Plain (ACP) with shallow lakes freezing solid (grounded ice) and deeper lakes maintaining perennial liquid water (floating ice). Thus, lake depth relative to maximum ice thickness (1·5–2·0 m) represents an important threshold that impacts permafrost,...
Arp, C.D.; Jones, Benjamin M.; Urban, F.E.; Grosse, G. Intercolony variation in growth of black brant goslings on the Yukon-Kuskokwim Delta, Alaska
Recent declines in black brant (Branta bernicla nigricans) are likely the result of low recruitment. In geese, recruitment is strongly affected by habitat conditions experienced by broods because gosling growth rates are indicative of forage conditions during brood rearing and strongly influence future survival and productivity. In 2006–2008, we...
Fondell, T.F.; Flint, Paul L.; Sedinger, J.S.; Nicolai, C.A.; Schamber, J.L. Modern thermokarst lake dynamics in the continuous permafrost zone, northern Seward Peninsula, Alaska
Quantifying changes in thermokarst lake extent is of importance for understanding the permafrost-related carbon budget, including the potential release of carbon via lake expansion or sequestration as peat in drained lake basins. We used high spatial resolution remotely sensed imagery from 1950/51, 1978, and 2006/07 to quantify changes in...
Jones, Benjamin M.; Grosse, G.; Arp, C.D.; Jones, M.C.; Walter, Anthony K.M.; Romanovsky, V.E. Molecular typing of Escherichia coli strains associated with threatened sea ducks and near-shore marine habitats of south-west Alaska
In Alaska, sea ducks winter in coastal habitats at remote, non-industrialized areas, as well as in proximity to human communities and industrial activity. We evaluated prevalence and characteristics of Escherichia coli strains in faecal samples of Steller's eiders (Polysticta stelleri; n = 122) and harlequin ducks (...
Hollmén, Tuula E.; DebRoy, Chitrita; Flint, Paul L.; Safine, David E.; Schamber, Jason L.; Riddle, Ann E.; Trust, Kimberly A. Polar bear population status in the northern Beaufort Sea, Canada, 1971-2006
Polar bears (Ursus maritimus) of the northern Beaufort Sea (NB) population occur on the perimeter of the polar basin adjacent to the northwestern islands of the Canadian Arctic Archipelago. Sea ice converges on the islands through most of the year. We used open-population capture–recapture models to estimate population size and vital rates...
Stirling, I.; McDonald, T.L.; Richardson, E.S.; Regehr, E.V.; Amstrup, Steven C. Potential shifts in dominant forest cover in interior Alaska driven by variations in fire severity
Large fire years in which >1% of the landscape burns are becoming more frequent in the Alaskan (USA) interior, with four large fire years in the past 10 years, and 79 000 km2 (17% of the region) burned since 2000. We modeled fire severity conditions for the entire area burned in large fires during a large fire year (2004) to determine the...
Barrett, K.; McGuire, A. David; Hoy, E.E.; Kasischke, E.S. Sea otter abundance in Kenai Fjords national Park: results from the 2010 aerial survey
A sea otter aerial survey was completed in Kenai Fjords National Park (KEFJ) during June of 2010. This was the third aerial survey completed since 2002 along the Kenai Peninsula, the second specifically conducted within KEFJ. Survey methodology followed the Bodkin and Udevitz (1999) method which accounts for imperfect detection. The survey took...
Coletti, Heather A.; Bodkin, James L.; Esslinger, George G. Short-term survival and effects of transmitter implantation into western grebes using a modified surgical procedure
Two pilot trials and one study in a closely related grebe species suggest that Western grebes (Aechmophorus occidentalis) will not tolerate intracoelomic transmitter implantation with percutaneous antennae and often die within days of surgery. Wild Western grebes (n = 21) were captured to evaluate a modified surgical technique. Seven birds were...
Gaydos, Joseph K.; Massey, J. Gregory; Mulcahy, Daniel M.; Gaskins, Lori A.; Nysewander, David; Evenson, Joseph; Siegel, Paul B.; Ziccardi, Michael H. Status and distribution of the Kittlitz's Murrelet Brachyramphus brevirostris along the Alaska Peninsula and Kodiak and Aleutian Islands, Alaska
The Kittlitz's Murrelet Brachyramphus brevirostris is adapted for life in glacial-marine ecosystems, being concentrated in the belt of glaciated fjords in the northern Gulf of Alaska from Glacier Bay to Cook Inlet. Most of the remaining birds are scattered along coasts of the Alaska Peninsula and Aleutian Islands, where they reside in protected...
