Evaluation Of Release Strategies For Captive-Reared June Sucker Based On Poststocking Survival, Eric J. Billman, Josh E. Rasmussen, Jackie Watson Jan 2012

Evaluation Of Release Strategies For Captive-Reared June Sucker Based On Poststocking Survival, Eric J. Billman, Josh E. Rasmussen, Jackie Watson

Western North American Naturalist

The recovery program for the endangered June sucker (Chasmistes liorus) relies on population augmentation to overcome recruitment deficits. Successful recruitment of artificially propagated individuals is affected by release timing, release size, and rearing techniques. We examined the effect of release timing and release size (total length [TL] and a relative condition factor [Wr]) on recruitment probability of hatchery-reared June sucker (Utah Division of Wildlife Resources Fisheries Experiment Station [FES]) and captive-reared June sucker (Red Butte Reservoir [RBR] refuge population) stocked across multiple years. Because source and year effects were confounded, we assessed the probability of recruitment …


Size-Structured Spatial Patterns As A Measure Of Larval Dispersal And Emigration, Douglas F. Markle Jan 2012

Size-Structured Spatial Patterns As A Measure Of Larval Dispersal And Emigration, Douglas F. Markle

Western North American Naturalist

Size-structured spatial patterns in larvae of 2 sucker and 3 minnow species are described from fixed-site sampling in Upper Klamath Lake, Oregon, and are used to demonstrate patterns of size-based losses downstream and retention in the lake. The smallest larvae of shortnose suckers (Chasmistes brevirostris), Lost River suckers (Deltistes luxatus), and tui chubs (Siphateles bicolor) were least likely to be found in Lake Ewauna, a downstream catchment; yet the proportion of larger larvae downstream was often substantial, 20%–40% of a size class. In contrast, the smallest larvae of blue chubs (Klamathella coerulea) …


Status Of Lost River Sucker And Shortnose Sucker, Josh E. Rasmussen Jan 2012

Status Of Lost River Sucker And Shortnose Sucker, Josh E. Rasmussen

Western North American Naturalist

The endangered Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) are endemic to the Upper Klamath Basin, Oregon and California. The once very abundant populations have declined drastically due to a combination of habitat loss and impairment, disruption of reproduction and gene flow, intensive harvest, and loss of entire populations. Spawning populations within Upper Klamath Lake are declining and have not had significant recruitment for over a decade. In addition to habitat loss, these populations are threatened by periodic harmful water conditions resulting from massive algal blooms and entrainment of larvae and juveniles into …


Consequences Of Parasitic Mite Infestation On Muskrat (Ondatra Zibethicus), Jeffrey A. Prendergast, William E. Jensen Jan 2012

Consequences Of Parasitic Mite Infestation On Muskrat (Ondatra Zibethicus), Jeffrey A. Prendergast, William E. Jensen

Western North American Naturalist

Ectoparasite infestation has been implicated in increased physiological costs and reduced fitness of several animals. The semiaquatic habit of muskrat (Ondatra zibethicus) restricts its ectoparasites to small mites. We assessed variation in muskrat reproductive effort and fat content in response to relative abundance of parasitic mites. There were no significant correlations between total number of placental scars, number of litters, or percent body fat and the relative abundance of ectoparasitic mites. Our results suggest that these measures of muskrat reproduction and physiology are generally unaffected by arachnid ectoparasites.


La infestación de ectoparásitos ha sido vinculada con el aumento …


Comparison Of Disturbance Impacts To And Spatial Distribution Of Biological Soil Crusts In The Little San Bernardino Mountains Of Joshua Tree National Park, California, Nicole Pietrasiak, Jeffrey R. Johansen, Tasha Ladoux, Robert C. Graham Jan 2012

Comparison Of Disturbance Impacts To And Spatial Distribution Of Biological Soil Crusts In The Little San Bernardino Mountains Of Joshua Tree National Park, California, Nicole Pietrasiak, Jeffrey R. Johansen, Tasha Ladoux, Robert C. Graham

Western North American Naturalist

Biological soil crust ecology in the hot Mojave Desert is poorly understood with regard to crust distribution and abundance, as well as the impacts of trampling disturbance on crust development. Our objective was to study biological soil crusts in 2 areas of differing disturbance pressures in the high desert region of Joshua Tree National Park, California, with respect to visible crust cover and frequency, chlorophylla, and soil stability. Impacts on biological soil crusts from 2 disturbance regimes, historic grazing and recent high foot traffic, were compared using a disturbance indicator. In addition, we measured a suite of abiotic and …


Characterization And Isolation Of Five Microsatellite Loci In Northern Flying Squirrels, Glaucomys Sabrinus (Sciuridae, Rodentia), A. M. Kiesow, L. E. Wallace, H. B. Britten Jan 2012

Characterization And Isolation Of Five Microsatellite Loci In Northern Flying Squirrels, Glaucomys Sabrinus (Sciuridae, Rodentia), A. M. Kiesow, L. E. Wallace, H. B. Britten

Western North American Naturalist

Northern flying squirrels (Glaucomys sabrinus) are found in boreal forests of northern and northwestern North America, but a small population is isolated to the Black Hills of South Dakota and Wyoming. Few microsatellite primers have been developed for this species, though they are needed to examine the genetic structure of these populations. Thus, we isolated and characterized 5 microsatellite loci in northern flying squirrels through a series of steps involving microbiology, molecular biology, and genetic techniques. Data analyses with these primers indicated that the northern flying squirrel population found in the Black Hills may have low heterozygosity and …

Lake Suckers In The Western Usa: History, Ecology, And Bibliography Of An Endangered Genus, Mark C. Belk, Russell B. Rader, Michael D. Mills Jan 2012

Lake Suckers In The Western Usa: History, Ecology, And Bibliography Of An Endangered Genus, Mark C. Belk, Russell B. Rader, Michael D. Mills

Western North American Naturalist

Lake suckers of the genus Chasmistes are a unique and important component of the fish assemblages of the western USA. To review recent research, discuss issues, and exchange information, researchers and managers working on the various species participated in a symposium on lake sucker biology as part of the 2010 annual meeting of the Western Division of the American Fisheries Society, held in Salt Lake City, Utah. This special feature of the Western North American Naturalist is dedicated to lake sucker ecology and natural history and provides a central venue for publication of several papers presented in the symposium. To …


Growth Of Young June Sucker (Chasmistes Liorus) Is Associated With Zooplankton Density In Utah Lake, Joshua D. Kreitzer, Eric J. Billman, Mark C. Belk, Russell B. Rader Jan 2012

Growth Of Young June Sucker (Chasmistes Liorus) Is Associated With Zooplankton Density In Utah Lake, Joshua D. Kreitzer, Eric J. Billman, Mark C. Belk, Russell B. Rader

Western North American Naturalist

The endangered June sucker, Chasmistes liorus, is a long-lived, zooplanktivorous sucker endemic to Utah Lake, Utah. Habitat degradation both in the tributaries, where adults spawn, and in the lake has contributed to near complete mortality of larval and juvenile fish within the first few weeks after hatching, leading to a long-term lack of recruitment to the adult population. Recovery of June sucker depends on habitat restoration in the river and the lake that will increase the survival of young fish. Thus, it is important to understand how habitat heterogeneity within the lake will influence the survival and growth of young …


Habitat Selection By Greater Sage-Grouse During Winter In Southeastern Oregon, Christian A. Hagen, Mitchell J. Willis, Elizabeth M. Glenn, Robert G. Anthony Jan 2012

Habitat Selection By Greater Sage-Grouse During Winter In Southeastern Oregon, Christian A. Hagen, Mitchell J. Willis, Elizabeth M. Glenn, Robert G. Anthony

Western North American Naturalist

The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important factor. Guidelines for protection and management of breeding and winter habitat have been developed for land managers, but winter habitat use has not been thoroughly described throughout the species’ range, particularly for the western portion of its range in Oregon. We examined vegetation-type selection and use by …


Diets Of Three Species Of Bufonids (Amphibia, Anura) From Northern Mexico, Geoffrey R. Smith, Julio A. Lemos-Espinal, Allison B. Burner, Kristen E. Winter, Christopher B. Dayer Jan 2012

Diets Of Three Species Of Bufonids (Amphibia, Anura) From Northern Mexico, Geoffrey R. Smith, Julio A. Lemos-Espinal, Allison B. Burner, Kristen E. Winter, Christopher B. Dayer

Western North American Naturalist

We examined the diets of 3 species of bufonids from northern Mexico (Anaxyrus debilis, Anaxyrus punctatus, and Incilius mazatlanensis) with the objective of better understanding the diets of amphibians in this region of Mexico, which is currently undergoing environmental change. The diet of A. debilis was numerically and volumetrically dominated by termites, followed by ants. In A. debilis, some aspects of prey size were correlated with toad head width but were not related to head length or body size (i.e., snout–vent length [SVL]). Ants were numerically the most important prey item in the diet of A. punctatus, but …

The Military And “Mob Rule”: The Cef Riots In Calgary, February 1916, P. Whitney Lackenbauer Jan 2012

The Military And “Mob Rule”: The Cef Riots In Calgary, February 1916, P. Whitney Lackenbauer

Canadian Military History

During the First World War, unruly and ill-disciplined Canadian soldiers, on “assorted ’patriotic’ pretexts,” damaged local property and battled with local police forces in Victoria, Calgary, Winnipeg, Toronto, Campbellton, New Brunswick, and other Canadian centres. The riots in Calgary in February 1916 involved members of Canadian Expeditionary Force (CEF) battalions encamped near the city. While historians have focused on the anti-German nature of the attacks, several other considerations must be examined to explain the unlawful behaviour. Although a court of inquiry into the riot failed to conclude who was responsible, the contemporary evidence suggests strongly that soldiers, rather than civilians, …


Providing The Gift Of Life: Canadian Medical Practitioners And The Treatment Of Shock On The Battlefield, Bill Rawling Jan 2012

Providing The Gift Of Life: Canadian Medical Practitioners And The Treatment Of Shock On The Battlefield, Bill Rawling

Canadian Military History

The story of Ambroise Pare’s discovery has been told often; of how, during Francis I’s campaign against Turin in 1536-37, he ran out of the oil medical practitioners used to cauterize the stumps of amputees and used an herbal remedy and ligatures instead; and of how the patients treated by the latter method did so much better than those tortured with the former. The tale has much to commend it to the popular imagination: a medical hero makes a serendipitous discovery to relieve the suffering of thousands. However, the story is an exception to a steadfast rule in warfare, for …


Army Supplies In The Forward Area And The Tumpline System: A First World War Canadian Logistical Innovation, F.R. Phelan Jan 2012

Army Supplies In The Forward Area And The Tumpline System: A First World War Canadian Logistical Innovation, F.R. Phelan

Canadian Military History

Editor’s Note: In British Logistics on the Western Front, 1914–1919 (Praeger, 1998), Ian M. Brown documents the problems of maintaining an army in the field; throughout that war, supply lines were strained to get food, equipment and ammunition forward. Early problems of adequate supplies were replaced by an inability to get the items from depots to where they were required. Some of these latter problems were blamed on “establishments” and other force-structure problems caused by stripping logistical-support units to meet the manpower needs of the fighting units. The decision to dramatically reduce the size of the BEF divisions in France …


The Gardeners Of Vimy: Canadian Corps’ Farming Operations During The German Offensives Of 1918, S.F. Wise Jan 2012

The Gardeners Of Vimy: Canadian Corps’ Farming Operations During The German Offensives Of 1918, S.F. Wise

Canadian Military History

“The Gardeners of Salonika” was Georges Clemenceau’s jibe at the French and British divisions tied down in entrenchments round the Greek port for a good part of the First World War, because all they seemed to do was dig, rather than launch a Balkan offensive. The Canadian Corps, from Field Marshal Haig’s perspective, was similarly removed from the war when Lieutenant-General Sir Arthur Currie, strongly supported by the Canadian government, refused to accept the piecemeal breakup of the Corps to help shore up the British line during the great German offensive which began in March 1918. Haig never forgave this …
