Utilization Of Spatially Distributed Soil Resources By Several Species Common To The Great Basin, Sarah Duke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Heterogeneous spatial and temporal distributions of soil resources important to plant growth have been documented in the sagebrush steppe ecosystem. There can exist as much variability in soil resources within the root zone of individual plants as exists across an entire field. The objective of this dissertation research was to evaluate how plants respond to, utilize and influence the spatial heterogeneity of soil resources. The three specific sets of questions addressed are outlined in the three main chapters of this dissertation.

My first study addressed how the number and concentration of phosphorus (P) patches in the root zone of an …

Perceived Fairness And Effectiveness Of Rangeland Collaborative Processes, Kimberly J. Richardson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Involvement in collaborative partnerships in natural resource management has become a popular method for natural resource management agencies to collect public input, cope with conflicts, and develop ecosystem management plans. This thesis evaluates various collaborative processes, emphasizing multiple-owner partnerships. Qualitative interviews of 46 landowners in Utah were conducted to reveal concerns and suggestions regarding multiple-owner landscape-level collaborative partnerships. Landowners were concerned about private property rights infringement and losing control of their private land. Landowners were primarily concerned about the fairness and effectiveness of any partnership in which they were involved.

However, they were willing to consider participating if certain procedural …

Effects Of Oxygen Variation On The Ecology Of Devil's Hole, Death Valley National Park, Norma J. Azad

UNLV Theses, Dissertations, Professional Papers, and Capstones

The inability to rear Devil's Hole pupfish, Cyprinodon diabolis Wales, in captivity, when captive propagation has been successful with other species of pupfish, led to the examination of environmental factors which are unique to Devil's Hole. It has been suggested that C. diabolis regularly experience developmental arrest due to hypoxic conditions. This arrest may be reversible in areas of the shallow shelf during periods of photosynthetic activity. Oxygen measurements over the shallow shelf reveal a gradient of oxygen variation with the greatest diel variability over the inner portion of the shelf diminishing to nearly imperceptible diel variation toward the outer …

Managing Island Biotas: Brown Treesnake Control Using Barrier Technology, Gad Perry, Earl W. Campbell Iii, Gordon H. Rodda, Thomas H. Fritts

United States Department of Agriculture Wildlife Services: Staff Publications

The brown treesnake (Boiga irregularis), accidentally introduced to the previously snake-free U.S. island of Guam after World War 11, decimated the island's naive wildlife. Today, it periodically stows away on craft going to other islands where the ecological damage may be repeated. Barriers offer an effective tool for keeping the snakes out of areas from which they can disperse off-island, as well as sites identified as critical for the protection of human health, conduct of economic activity, or conservation of endangered species. The authors have developed a variety of barrier designs which repulse at least 95% of snake …

A Review Of The Case Histories Of The Brown Tree Snakes (Boiga Irregularis) Located By Detector Dogs On Guam, Richard M. Engeman, Danny V. Rodriguez, Michael A. Linnell, Mikel E. Pitzler

United States Department of Agriculture Wildlife Services: Staff Publications

Records of 34 brown tree snakes detected during dog inspections were examined to describe the situations in which snakes were found and to determine probable destinations had they successfully departed Guam. A key to the use of detector dogs for interdicting brown tree snake transport from Guam is that the snakes found are at high risk for export. Hawaii. followed by the Micronesian islands. were the most frequently identified potential destinations for the snakes located by dogs. Published by Elsevier Science Ltd.

Trapping Strategies For Deterring The Spread Of Brown Tree Snakes From Guam, Richard M. Engeman, Michael A. Linnell

United States Department of Agriculture Wildlife Services: Staff Publications

The accidental introduction of the Brown Tree Snake Boiga Irregularis to Guam has resulted in the extirpation of most of the island's native terrestrial vertebrates, has presented a health hazard to infants and children, and also has produced an economic problem. Prevention of its dispersal through Guam's cargo traffic to other Pacific islands has became a high environmental priority. Trapping around ports and other cargo staging areas is central to an integrated pest management program designed to deter dispersal of the species. In this study, perimeter trapping of forested plots characteristic of those found in port areas was found 19 …

Comparative Developmental Toxicity Of Planar Polychlorinated Biphenyl Congeners In Chickens, American Kestrels, And Common Terns, David J. Hoffman, Mark J. Melancon, Patrice N. Klein, John D. Eisemann, James W. Spann

United States Department of Agriculture Wildlife Services: Staff Publications

The effects of polychlorinated biphenyl (PCB) congeners, PCB 126 (3,3′, 4,4′, 5-pentaCB) and PCB 77 (3,3′4,4′-tetraCB), were examined in chicken (Gallus gallus), American kestrel (Falco sparverius), and common tern (Sterna hirundo) embryos through hatching, following air cell injections on day 4. PCB 126 caused malformations and edema in chickens starting at 0.3 ppb, in kestrels at 2.3 to 23 ppb, but in terns only at levels affecting hatching success (44 ppb). Extent of edema was most severe in chickens and least in terns. Defects of the beak were common in all species but with …

Predation On Atlantic Salmon Smolts By Striped Bass After Dam Passage, Bradley F. Blackwell, Francis Juanes

United States Department of Agriculture Wildlife Services: Staff Publications

We documented predation on smolts of Atlantic salmon Salmo salar by striped bass Morone saxatilis foraging in the tailrace of the Essex Dam on the Merrimack River, Lawrence, Massachusetts, and assessed factors that may affect smolt susceptibility to predation. During 6 d of diurnal angling from 6 to 28 May, we captured 212 striped bass, 41 of which contained prey remains. More than 48% of striped bass that contained prey had consumed smolts. Atlantic salmon smolts composed more than 80% of the total mass of prey remains recovered and included both individuals of stocked-fry and stocked-smolt origin. Based on information …

Laboratory Evaluation Of Predator Odors For Eliciting An Avoidance Response In Roof Rats (Rattus Rattus), Michael D. Burwash, Mark E. Tobin, Anthony D. Woolhouse, Thomas P. Sullivan

United States Department of Agriculture Wildlife Services: Staff Publications

We evaluated eight synthetic predator odors and mongoose (Herpestes auropunctatus) feces for eliciting avoidance responses and/or reduced feeding by wild captured Hawaiian roof rats (Rattus rattus). In a bioassay arena, we recorded: (1) time until each rat entered the arena, (2) time elapsed until first eating bout, (3) time spent in each half of the arena, (4) number of eating bouts, and (5) consumption. Rats displayed a response to the predator odors in terms of increased elapsed time before initial arena entry and initial eating bout, a lower number of eating bouts, and less food consumption …

School of Natural Resources: Faculty Publications

We analyzed the relationship between new ecosystem exchange of carbon dioxide (NEE) and irradiance (as photosynthetic photon flux density of PPFD), using published and unpublished data that have been collected during midgrowing season for carbon balance studies at seven peatlands in North America and Europe. NEE measurements included both eddy-correlation tower and clear, static chamber methods, which gave very similar results. Data were analyzed by site, as aggregated data set for all peatland type (bog, poor fen, rich fen, and all fens) and as a single aggregated data set for all peatlands. In all cases, a fit with a rectangular …

The Efficacy Of Glue Traps Against Wild Populations Of House Mice, Mus Domesticus, Rutty, Robert M. Corrigan

Vertebrate Pest Conference Proceedings: 18th (1998)

Field research was conducted from Purdue University during 1991 to 1993 to examine some aspects of the efficaciousness of the various types of glue traps against wild populations of house mice. The research was conducted in agricultural and livestock buildings containing various infestation levels of mice. Tests compared the capture and escape rates of glue boards vs. trays, covered vs. uncovered glue traps, and glue traps vs. snap traps, and multiple catch curiosity traps. Observational work, via night vigils, was also conducted to note the behavioral response of mice to glue surfaces, including the behavioral aspects of mice neutralizing glue …
