Moose, Caribou, and Grizzly Bear Distribution in Relation to Road Traffic in Denali National Park, Alaska
Studies moose or Alces alces, caribou or Rangifer tarandus and grizzly bear or Ursus arctos distribution in relation to road traffic in Denali National Park, Alaska. Development of wildlife monitoring system using 19 landscape level viewsheds stratified into four sections based on decreasing traffic along the road corridor; Absence of traffic avoidance patterns for caribou and grizzly bears.
Population characteristics, space use and habitat selection of two non-migratory caribou herds in central Alaska, 1994 - 2009
Nutritional restrictions in winter may reduce the availability of protein for reproduction and survival in northern ungulates. We refined a technique that uses recently voided excreta on snow to assess protein status in wild caribou (Rangifer tarandus) in late winter. Our study was the first application of this non-invasive, isotopic approach to assess protein status of wild caribou by determining dietary and endogenous contributions of nitrogen (N) to urinary urea. We used isotopic ratios of N (?15N) in urine and fecal samples to estimate the proportion of urea N derived from body N (p-UN) in pregnant, adult females of the Chisana Herd, a small population that ranged across the Alaska-Yukon border. We took advantage...
Caribou Hunters and Researchers at the Co-management Interface: Emergent Dilemmas and the Dynamics of Legitimacy in Power Sharing
A content analysis of PCMB meeting minutes from its first meeting to 1993 reveals a repeated pattern of communication in which Native hunters pose questions about the need for caribou research requiring the use of aircraft and collars and the handling of animals, and a response by agency managers to inform community residents about the value of collars in science and/or demonstrating their application. Never discussed openly at PCMB meetings was what the Gwich'in regard as a negotiated order of power-sharing arrangement between Gwich'in and caribou, established in the time before there was time, nunh ttrotsit ultsui gwuno (when the earth was first made), when caribou were people and people were caribou. As told...

Diversity of nitrogen isotopes and protein status in caribou: implications for monitoring northern ungulates
Fishery Management Report for Sport Fisheries in the Arctic-Yukon- Kuskokwim Management Area, 1999-2000
Report is divided into three sections. In Section I, an overview of the Arctic-Yukon-Kuskokwim Management Area is provided, including a description of the area and subareas, Board of Fish activities, and management information and activities.

Ecological effects of invasive European bird cherry (Prunus padus) on salmonid food webs in Anchorage, Alaska streams
Invasive species are a concern worldwide as they can displace native species, reduce biodiversity, and disrupt ecological processes. European bird cherry (Prunus padus) (EBC) is an invasive ornamental tree that is rapidly spreading and possibly displacing native trees along streams in parts of urban Alaska. The objectives of this study were to: 1) map the current distribution of EBC along two Anchorage streams, Campbell and Chester creeks, and 2) determine the effects of EBC on selected ecological processes linked to stream salmon food webs. Data from the 2009 and 2010 field seasons showed: EBC was widely distributed along Campbell and Chester creeks; EBC leaf litter in streams broke down rapidly and supported similar...
