    Selkirk Mountains Grizzly Bear Recovery Area 2015 Research and Monitoring Progress Report

    SELKIRK MOUNTAINS GRIZZLY BEAR RECOVERY AREA 2015 RESEARCH AND MONITORING PROGRESS REPORT PREPARED BY WAYNE F. KASWORM, ALEX WELANDER, THOMAS G. RADANDT, JUSTIN E. TEISBERG, WAYNE L. WAKKINEN, MICHAEL PROCTOR, AND CHRISTOPHER SERVHEEN 2016 UNITED STATES FISH AND WILDLIFE SERVICE GRIZZLY BEAR RECOVERY COORDINATOR'S OFFICE UNIVERSITY OF MONTANA, MAIN HALL ROOM 309 MISSOULA, MONTANA 59812 (406) 243-4903 1 Abstract: Idaho Department of Fish and Game (IDFG) captured and monitored a radio collared sample of grizzly bears in the SMGBRZ from 1983 until 2002 to determine distribution, home ranges, cause specific mortality, reproductive rates, and population trend. This effort was suspended in 2003 due to funding constraints and management decisions. In cooperation with IDFG and the Panhandle National Forest (USFS) this effort was reinitiated during 2012 with personnel from the U.S. Fish and Wildlife Service (USFWS). During 2013 the program was expanded with funding from IDFG, USFS, several sources in British Columbia (BC), and USFWS. This cooperative research and monitoring effort was expanded to involve Idaho Department of Lands, the Kalispel Tribe, the Kootenai Tribe of Idaho, and Washington Department of Fish and Wildlife in 2014 Numbers of females with cubs in the Selkirk Mountains grizzly bear recovery zone (SMGBRZ) varied from 0–4 per year and averaged 1.5 per year from 2010–15. Human caused mortality averaged 1.7 bears per year and 0.7 females per year. Ten human caused mortalities during 2010-15 include 4 females (all BC) and 6 males (one US and five BC). Human caused mortalities during 2010-15 were four adult females (one vehicle collision and three under investigation), one adult male (management), and four subadult males (two management, one mistaken identity, and one self-defense).

NAGORSEN,4,5 AND JACK SULLIVAN1 1Department of Biological Sciences, Box 443051, University of Idaho, Moscow, Idaho 83844-3051 3Biological Sciences Department, California State Polytechnic University, Pomona, 3801 West Temple Avenue, Pomona, California 91768-4032 4Royal British Columbia Museum, Victoria, British Columbia V8V 1X4, Canada Abstract. If phylogeographic studies are to be broadly used for assessing population-level processes relevant to speciation and systematics, the ability to identify and incorporate instances of hybridization into the analytical frame- work is essential. Here, we examine the evolutionary history of two chipmunk species, Tamias ru®caudus and Tamias amoenus, in the northern Rocky Mountains by integrating multivariate morphometrics of bacular (os penis) variation, phylogenetic estimation, and nested clade analysis with regional biogeography. Our results indicate multiple examples of mitochondrial DNA introgression layered within the evolutionary history of these nonsister species. Three of these events are most consistent with recent and/or ongoing asymmetric introgression of mitochondrial DNA across mor- phologically de®ned secondary contact zones. In addition, we ®nd preliminary evidence where a fourth instance of nonconcordant characters may represent complete ®xation of introgressed mitochondrial DNA via a more ancient hybridization event, although alternative explanations of convergence or incomplete sorting of ancestral polymorphisms cannot be dismissed with these data. The demonstration of hybridization among chipmunks with strongly differentiated bacular morphology contradicts long-standing assumptions that variation within this character is diagnostic of complete reproductive isolation within Tamias.

  • Avalanche Characteristics of a Transitional Snow Climate—Columbia Mountains, British Columbia, Canada

    Avalanche Characteristics of a Transitional Snow Climate—Columbia Mountains, British Columbia, Canada

    Cold Regions Science and Technology 37 (2003) 255–276 www.elsevier.com/locate/coldregions Avalanche characteristics of a transitional snow climate—Columbia Mountains, British Columbia, Canada Pascal Ha¨gelia,*, David M. McClungb a Atmospheric Science Program, University of British Columbia, 1984 West Mall, Vancouver, British Columbia, Canada V6T 1Z2 b Department of Geography, University of British Columbia, Vancouver, British Columbia, Canada Received 1 September 2002; accepted 2 July 2003 Abstract The focus of this study lies on the analysis of avalanche characteristics in the Columbia Mountains in relation to the local snow climate. First, the snow climate of the mountain range is examined using a recently developed snow climate classification scheme. Avalanche observations made by a large helicopter operator are used to examine the characteristics of natural avalanche activity. The results show that the Columbia Mountains have a transitional snow climate with a strong maritime influence. Depending on the maritime influence, the percentage of natural avalanche activity on persistent weak layers varies between 0% and 40%. Facet–crust combinations, which primarily form after rain-on-snow events in the early season, and surface hoar layers are the most important types of persistent weak layers. The avalanche activity characteristics on these two persistent weak layers are examined in detail. The study implies that, even though the ‘avalanche climate’ and ‘snow climate’ of an area are closely related, there should be a clear differentiation between these two terms, which are currently used synonymously. We suggest the use of the term ‘avalanche climate’ as a distinct adjunct to the description of the snow climate of an area.
