Comparative Tolerance Of Four Stocks Of Cuttthroat Trout To Extremes In Temperature, Salinity, And Hypoxia, Eric J. Wagner, Ronney E. Arndt, Mark Brough Nov 2001

Comparative Tolerance Of Four Stocks Of Cuttthroat Trout To Extremes In Temperature, Salinity, And Hypoxia, Eric J. Wagner, Ronney E. Arndt, Mark Brough

Western North American Naturalist

Four stocks of cutthroat trout (Oncorhynchus clarki) were exposed to high temperature, high salinity, and low dissolved oxygen to determine inherent differences. The fish tested included 2 stocks of Bonneville cutthroat trout (O. c. utah), a lacustrine stock derived from Bear Lake and a fluvial-origin stock from southern Utah (Manning Meadow Reservoir). The other 2 stocks tested were from Electric Lake (largely Yellowstone cutthroat trout, O. c. bouvieri) and Jackson Hole, Wyoming (fine-spotted Snake River cutthroat trout, O. c. subsp.). Temperature tests were either critical thermal maximum (CTM) or 96-hour trials using juveniles acclimated between …

Physiological, Morphological, And Environmental Variation Among Geographically Isolated Cottonwood (Populus Deltoides) Populations In New Mexico, Diane L. Rowland, Lucille Beals, Amina A. Chaudhry, Ann S. Evans, Larry S. Grodeska Nov 2001

Physiological, Morphological, And Environmental Variation Among Geographically Isolated Cottonwood (Populus Deltoides) Populations In New Mexico, Diane L. Rowland, Lucille Beals, Amina A. Chaudhry, Ann S. Evans, Larry S. Grodeska

Western North American Naturalist

The ability of a plant population to respond and eventually adapt to environmental stress ultimately determines that population's survival. This becomes especially significant in environments where important plant resource levels have radically decreased. Southwestern riparian areas have numerous plant species that are experiencing radical changes in water availability due to construction of dams, and thus their ability to respond to such changes is critical. One such species likely to be greatly affected by these hydrological changes is Populus deltoides var. wislizenii (cottonwood) because it relies heavily on both groundwater and river surface volume as primary water sources. Both water sources …

Exotic Plants In Early And Late Seral Vegetation Of Fifteen Northern Rocky Mountain Environments (Hts), T. Weaver, D. Gusafson, J. Lichthardt Nov 2001

Exotic Plants In Early And Late Seral Vegetation Of Fifteen Northern Rocky Mountain Environments (Hts), T. Weaver, D. Gusafson, J. Lichthardt

Western North American Naturalist

We determined the capacity of exotic plants to invade major environmental types of the northern Rocky Mountains. We did this by observing their presence on disturbed and undisturbed sites in relatively well inoculated locations—corridors adjacent to highways—on transects across the mountains in Glacier National Park and Grand Teton National Park and on low-altitude sites between them. We draw 3 primary conclusions. First, of 29 exotics commonly found, the most dominant are intentionally introduced grasses (Agrostis, Bromus, Dactylis, and especially Phleum pratense and Poa pratensis) and legumes (Melilotus, Medicago, and Trifolium) rather than the forbs …


Experimental Manipulations Of Precipitation Seasonality: Effects On Oak (Quercus) Seedling Demography And Physiology, Jake F. Weltzin, Keirith A. Snyder, David G. Williams Nov 2001

Experimental Manipulations Of Precipitation Seasonality: Effects On Oak (Quercus) Seedling Demography And Physiology, Jake F. Weltzin, Keirith A. Snyder, David G. Williams

Western North American Naturalist

Predicted changes in regional precipitation patterns and soil moisture caused by anthropogenic trace gas emissions may affect the distribution and abundance of woody plants in arid and semiarid regions. To test the response of woody plants to potential changes in precipitation regimes, we manipulated summer and winter precipitation on plots that contained seedlings of Quercus emoryi Torr. (Emory oak), the dominant tree in oak savannas of the southwestern United States. Throughout the growing season, we monitored seedling survival and physiology (predawn leaf water potential, midday instantaneous gas exchange, and leaf carbon isotope discrimination). Seedling survival and physiological performance differed little …


A Habitat Suitability Model For Pygmy Rabbits (Brachylagus Idahoensis) In Southeastern Idaho, Kate I. Gabler, Laura T. Heady, John W. Laundré Nov 2001

A Habitat Suitability Model For Pygmy Rabbits (Brachylagus Idahoensis) In Southeastern Idaho, Kate I. Gabler, Laura T. Heady, John W. Laundré

Western North American Naturalist

A habitat suitability model was developed for pygmy rabbit (Brachylagus idahoensis) habitat on the Idaho National Engineering and Environmental Laboratory (INEEL) in southeastern Idaho. Suitable pygmy rabbit areas were characterized by greater cover and density of total shrubs and big sagebrush (Artemisia tridentata), as well as greater forb cover. Soil texture also played an important role in distinguishing suitable pygmy rabbit areas from nonuse sites. Principal components analysis (PCA) of several vegetation variables and soil texture was used to develop a habitat suitability model for pygmy rabbit habitat. This model, which can be used to successfully …

A Rule-Based Model For Mapping Potential Exotic Plant Distribution, Don G. Despain, T. Weaver, Richard J. Aspinall Nov 2001

A Rule-Based Model For Mapping Potential Exotic Plant Distribution, Don G. Despain, T. Weaver, Richard J. Aspinall

Western North American Naturalist

Wildland managers need a method to predict which portions of the lands under their stewardship are susceptible to invasion by exotic plants. We combined a database listing exotic plant species known to occur in major environmental types (habitat types) throughout the northern Rocky Mountains with a digital vegetation map of environmental types for a major national park in the region (Yellowstone National Park) to produce maps of areas potentially threatened by major exotic species. Such maps should be helpful to managers concerned with monitoring and controlling exotic plants.

Biology And Conservation Of The Coral Pink Sand Dunes Tiger Beetle, Cicindela Limbata Albissima Rumpp, C. Barry Kinsley, James M. Hill Nov 2001

Biology And Conservation Of The Coral Pink Sand Dunes Tiger Beetle, Cicindela Limbata Albissima Rumpp, C. Barry Kinsley, James M. Hill

Western North American Naturalist

This study investigated the distribution, abundance, and biology of Cicindela limbata albissima Rumpp, an endemic tiger beetle known only from the Coral Pink Sand Dunes (CPSD) in southwestern Utah. A recently implemented conservation agreement between BLM, USFWS, Utah State Parks, and Kane County protects most of the known habitat of this beetle from off-highway vehicle (OHV) use. A search of collection records and field surveys of 19 Great Basin sand dune sites indicated that this species occurs only at CPSD. Yearly index counts of adults (1992–1998) during peak season in May ranged from 331 in 1997 to 895 in 1993, …

The Impact Of Publicly Funded Research On The Structure Of U.S. Agriculture, Jeffrey S. Royer Nov 2001

The Impact Of Publicly Funded Research On The Structure Of U.S. Agriculture, Jeffrey S. Royer

Cornhusker Economics

In recent years, there has been a substantial increase in the concentration of agricultural production in the United States as the number of farming and ranching operations has declined and the average size of those operations has grown. This increased concentration has been accompanied by increased coordination of production and marketing activities through contracting, consolidation and vertical integration. Although independent family farms and ranches have been responsible for most of the nation’s agricultural production historically, small and medium-sized operations are finding it difficult to compete in today’s increasingly industrialized food and agricultural sector.
