First Record Of Corisella Inscripta (Uhler) (Heteroptera: Corixidae) From North Dakota, Bruce A. Hanson, David M. Mushet, Ned A. Euliss Jr., Stephen Chordas Iii May 2007

First Record Of Corisella Inscripta (Uhler) (Heteroptera: Corixidae) From North Dakota, Bruce A. Hanson, David M. Mushet, Ned A. Euliss Jr., Stephen Chordas Iii

The Prairie Naturalist

Corisella inscripta is a water boatman species that was reported in H. B. Hungerford's (1948) seminal monograph as occurring throughout Mexico and nine western states of the United States. Subsequently, additional records of C. inscripta have been reported for British Columbia in Canada (Maw et al. 2000) and for Montana (Roemhild 1976), Arkansas (Cochran and Harp 1990), Missouri (Polhemus et al. 1988), Ohio (Chordas and Armitage 1998), and Michigan (Chordas et al. 2002) in the United States. There have been no published records of C. inscripta from North Dakota (Fig. I). We collected one male C. inscripta at the Cottonwood …


Review Of Some Scarce Birds Of The Upper Midwest By Dana Gardner And Nancy Overcott, Stephen J. Dinsmore May 2007

Review Of Some Scarce Birds Of The Upper Midwest By Dana Gardner And Nancy Overcott, Stephen J. Dinsmore

The Prairie Naturalist

Fifty Uncommon Birds of the Upper Midwest. Watercolors by Dana Gardner; text by Nancy Overcott. 2007. University of Iowa Press, Iowa City, Iowa. 112 pages. $34.95 (cloth).

Nancy Overcott has written series of short essays of birds found in the Upper Midwest and assembled them in an easy-to-read book. As an ornithologist and avid birder in this region, I'll admit that I didn't know what to expect when I opened the cover-would the focus be on rarities, would there be an identification component, are there tips for finding each species, and at what audience was the book aimed? Ultimately, I …

Biological Sciences: Faculty Publications

Disturbance may cause community composition across sites to become more or less homogenous, depending on the importance of different processes involved in community assembly. In north-eastern North America and Europe local (alpha) diversity of forest plants is lower in forests growing on former agricultural fields (recent forests) than in older (ancient) forests, but little is known about the influence of land-use history on the degree of compositional differentiation among sites (beta diversity). Here we analyse data from 1446 sites in ancient and recent forests across 11 different landscapes in north-eastern North America and Europe to demonstrate decreases in beta diversity …


Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia May 2007

Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia

Senior Honors Projects

Many bird species that require early successional forest are declining in the Northeast U.S. because such habitat is relatively rare and when they inhabit the more common mature forests or suburban areas they are less successful. Early successional forest is maintained by regular disturbance (wind, fire, clear-cutting, and flooding) which has been happening less frequently during the past 50 years. Bird species that have declined during this time and which inhabit early successional forest include ruffed grouse (Bonasa umbellus), blue jay (Cyanocitta cristata), chestnut-sided warbler (Dendroica pensylvanica), gray catbird (Dumetella carolinensis), field sparrow (Spizella pusilla), golden-winged warbler (Vermivora chrysoptera), eastern …

Population Viability Analysis Of Monk Parakeets In The United States And Examination Of Alternative Management Strategies, Stephen Pruett-Jones, James R. Newman, Christian M. Newman, Michael L. Avery, James R. Lindsay

United States Department of Agriculture Wildlife Services: Staff Publications

In the United States, monk parakeets (Myiopsitta monachus) are expanding their geographical distribution, and their overall population size is growing exponentially. Monk parakeets are causing widespread economic damage in the United States by nesting on utility structures, which leads to electrical fires and power outages. Although few life history data are available for the species from North America, extensive data are available from the species’ native range in South America. Incorporating data from South America into the population viability analysis program VORTEX, we simulated population growth in United States monk parakeets to determine whether it is likely that …


Southern Nevada Agency Partnership Conservation Education And Interpretation Strategy, Allison Brody May 2007

Southern Nevada Agency Partnership Conservation Education And Interpretation Strategy, Allison Brody

Education about the Environment

Four federal agencies manage seven million acres of federal lands in Southern Nevada. Increasing demands for use of these public lands has created the need for those agencies to form a unique interagency partnership and to work cooperatively in support of agency missions, protection of natural resources, and public service.

The Bureau of Land Management (BLM) Las Vegas Field Office, National Park Service (NPS) Lake Mead National Recreation Area, the Fish and Wildlife Service (FWS) Desert National Wildlife Refuge Complex, and the U.S. Forest Service (USFS) Spring Mountains National Recreation Area formed the Southern Nevada Agency Partnership (SNAP) in 1997 …


Comparison Of Water Dynamics In Aspen And Conifer: Implications For Ecology Water Yield Augmentation, Eric Martin Lamalfa May 2007

Comparison Of Water Dynamics In Aspen And Conifer: Implications For Ecology Water Yield Augmentation, Eric Martin Lamalfa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differences in water dynamics between deciduous aspen (Populus tremuloides) and co-occurring evergreen conifer species in the Northern Rocky Mountains result from complex physical and biological interactions. A comprehensive evaluation of individual water transfer mechanisms was used to elucidate the relative importance of several components of the hydro logic cycles of aspen and conifer, and determine which water transfer mechanisms have potential to cause differences in net water yield.

Adjacent aspen and conifer stands were monitored to determine snow accumulation and ablation (snow survey), soil moisture recharge (capacitance probes), snowpack sublimation (sublimation pan), transpiration period (thermal dissipation probes), and …


Bats And Mines: Evaluating Townsend's Big-Eared Bat Maternity Colony Response To Reclamation, Gabrielle F. Diamond May 2007

Bats And Mines: Evaluating Townsend's Big-Eared Bat Maternity Colony Response To Reclamation, Gabrielle F. Diamond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the loss or modification of natural roosting habitat afforded by caves, abandoned mines have assumed increased importance as surrogate roosting sites for Townsend's big-eared bats (Corynorhinus townsendii) and other chiropteran species. However, increasing concerns for human safety have led to accelerated programs for mine closure. In efforts to protect roosting sites in mines showing significant bat activity, "bat compatible" gates are installed, thus allowing continued access to mine workings. Aside from ensuring public safety, these structures afford protection from disturbance to roosting bats. To date few posting-gating studies have been conducted to obtain information on the effects …


The Timing And Magnitude Of Channel Adjustments In The Upper Green River Below Flaming Gorge Dam In Browns Park And Lodore Canyon, Colorado: An Analysis Of The Pre- And Post-Dam River Using High-Resolution Dendrogeomorphology And Repeat Topographic Surveys, Jason S. Alexander May 2007

The Timing And Magnitude Of Channel Adjustments In The Upper Green River Below Flaming Gorge Dam In Browns Park And Lodore Canyon, Colorado: An Analysis Of The Pre- And Post-Dam River Using High-Resolution Dendrogeomorphology And Repeat Topographic Surveys, Jason S. Alexander

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Channel narrowing on the Green River in Utah and Colorado has been well documented by several authors and has been attributed to reductions in flow after 1930, the construction of Flaming Gorge Dam (FGD), and the invasion of the woody riparian plant Tamarisk (tamarix ramosissima). Narrowing has occurred through the deposition of inset floodplains, which have vertically accreted within a previously larger active channel. Prior to closure of FGD, lower magnitude floods aggraded surfaces in the areas of the channel that had the highest divergence in the velocity flow field (i.e. bars and banks). These surfaces later became …


Extraction Method Development And In Vivo And In Vitro Toxicity Studies Of The Etiologic Agent Of Avian Vacuolar Myelinopathy, Faith Wiley May 2007

Extraction Method Development And In Vivo And In Vitro Toxicity Studies Of The Etiologic Agent Of Avian Vacuolar Myelinopathy, Faith Wiley

All Dissertations

Avian vacuolar myelinopathy (AVM) is a neurological disease affecting birds in the southeastern United States. The cause of the disease has not yet been determined but is believed to be a naturally produced toxin and is associated with aquatic vegetation. Current research on AVM is limited to in vivo studies utilizing whole tissue or vegetative samples. The objectives of this research were to develop extraction methods for isolating the putative AVM toxin from vegetative samples and to develop an in vitro bioassay for detection and study of the toxin. Samples of vegetation were collected from reservoirs known to be affected …


Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller Apr 2007

Suburban Coyote Management And Research Needs: A Northeast Perspective, Paul D. Curtis, Daniel A. Bogan, Gordon Batcheller

Wildlife Damage Management Conference Proceedings

Several factors may be responsible for increasing predator abundance in suburbia. These include an enhanced forage base associated with residential sprawl, and protection of predator species that were once persecuted and suppressed by hunters, trappers, and landowners. In the Northeast, anecdotal reports of coyotes (Canis latrans) killing pets in backyards are on the rise. The bulk of coyote complaints, concerns, and questions received from the public by state wildlife agencies are from areas with high human populations. Scant research exists on coyote behavioral ecology in human-altered landscapes. Biologists and managers need to understand changes in the social structure …


Pest Risk Assessment For Feral Pigs In Oregon, Bruce Coblentz, Cassie Bouska Apr 2007

Pest Risk Assessment For Feral Pigs In Oregon, Bruce Coblentz, Cassie Bouska

Other Publications in Wildlife Management

Feral pigs, wild boars, and hybrids either currently inhabit, or have been successfully introduced to every continent except Antarctica, and many oceanic islands. There are thirteen current known localities of feral pigs in Oregon (see Appendix A), distributed in various locations in southern and central Oregon. The biology of feral pigs indicates that these animals are capable of inhabiting virtually all available habitat west of the Cascade mountains, and the majority of the habitat east of the Cascades, with preference for riparian regions. Reports of feral pig biology and ecology in other regions in the United States, as well as …

Nicarbazin Ovocontrol G Bait Reduces Hatchability Of Eggs Laid By Resident Canada Geese In Oregon, Kimberly Bynum, John D. Eisemann, Gary C. Weaver, Christi A. Yoder, Kathleen A. Fagerstone, Lowell A. Miller

United States Department of Agriculture Wildlife Services: Staff Publications

Expanding populations of resident Canada geese (Branta canadensis) are resulting in increased conflicts with humans. Nonlethal and humane means are needed for managing Canada goose flocks at a variety of sites, including golf courses, industrial parks, government sites, and city parks. Decreased egg production and hatching are side effects of nicarbazin, a veterinary drug used to treat coccidiosis in chickens. Capitalizing on these effects, we developed nicarbazin as a reproductive inhibitor for Canada geese and conducted a field efficacy study. We recruited study sites in 2002 and 2003. Following laboratory testing, we conducted a field efficacy trial of …


The Successful Eradication Of Introduced Roof Rats (Rattus Rattus) From Buck Island Using Diphacinone, Followed By An Irruption Of House Mice (Mus Musculus), Gary W. Witmer, Frank Boyd, Zandy Hillis-Starr Apr 2007

The Successful Eradication Of Introduced Roof Rats (Rattus Rattus) From Buck Island Using Diphacinone, Followed By An Irruption Of House Mice (Mus Musculus), Gary W. Witmer, Frank Boyd, Zandy Hillis-Starr

United States Department of Agriculture Wildlife Services: Staff Publications

The United States National Park Service and the United States Wildlife Services made a planned and sustained effort to eradicate the introduced roof rats (Rattus rattus) from Buck Island Reef National Monument in the Caribbean Sea during 1998–2000. The rats were causing substantial damage to a variety of the 80-ha island’s floral and faunal resources. An island-wide grid of elevated bait stations containing anticoagulant (0.005% diphacinone; 50 ppm) rodenticide bait blocks were used to eradicate the rats. The bait stations were modified several times to assure ready access by rats while minimizing access by non-target animals, especially crabs …

Cattail Distribution End Abundance In North Dakota, Scott T. Ralston, G. M. Linz, W. J. Bleier, H. J. Homan

United States Department of Agriculture Wildlife Services: Staff Publications

Wetlands in the Prairie Pothole Region (PPR) of North Dalcota provide important habitats for a plethora of invertebrate and vertebrate animals. Since 1991, glyphosate-based (N-phosphonomethyl-glycine) herbicides have been used to manage dense cattail (Typha spp. L.) stands on 29,522 ha of wetlands in the PPR to disperse blackbird roosts. Limited information exists on the abundance and distribution of this important habitat. We took aerial photographs and used geospatial analysis tools to identify wetland basins and cattail coverage on randomly selected sample sites within the PPR. We found that average wetland density and size were 13 wetlands/ km2 and …

This paper examines long-term eddy covariance data from 18 European and 17 North American and Asian forest, wetland, tundra, grassland, and cropland sites under nonwater- stressed conditions with an empirical rectangular hyperbolic light response model and a single layer two light-class carboxylase-based model. Relationships according to ecosystem functional type are demonstrated between empirical and physiological parameters, suggesting linkages between easily estimated parameters and those with greater potential for process interpretation. Relatively sparse documentation of leaf area index dynamics at flux tower sites is found to be a major difficulty in model inversion and flux interpretation. Therefore, a simplification of the …

Selected Chemistry Of Biologically-Active Thiols : N-Acetylpenicillamine And 2-Mercaptobenzothiazole In Nitrosothiol Formation And Role In Allergic Contact Dermatitis Respectively, Itai Chipinda

Dissertations and Theses

Two biologically-active thiols, N-acetylpenicillamine (NAP) and 2-mercaptobenzothiazole (MBT), were studied in this thesis. NAP is known to combine with nitric oxide (NO) to produce S-nitroso-N-acetylpenicillamine (SNAP) and MBT is a known allergen.

The formation, reaction dynamics, and detailed kinetics and mechanism of the reaction between nitrous acid (HNO2), prepared in situ, and NAP to produce SNAP were studied. The reaction is first order in nitrite, NAP and acid in pH conditions at or slightly higher than the pKa of HNO2. Both HPLC and quadrupole time-of-flight mass spectrometry techniques confirmed the formation of SNAP and the absence of any other products. …

Interleukin-6 And Tumor Necrosis Factor-Alpha Values In Elk Neonates, Shannon M. Barber-Meyer, Craig R. Johnson, Michael P. Murtaugh, L. David Mech, P.J. White

United States Department of Agriculture Wildlife Services: Staff Publications

Serological indicators of general condition would be helpful for monitoring or assessing ungulate wildlife. Toward that end, we report the 1st reference values for 2 cytokines, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-a), in neonatal elk (Cervus elaphus). We obtained blood samples from 140 calves ≤ 6 days old in Yellowstone National Park during summer 2003–2005. IL-6 values ranged from 0 to 1.21 pg/ml with a median of 0.03 pg/ml. TNF-a values ranged from 0 to 225.43 pg/ml with a median of 1.85 pg/ml. IL-6 and TNF-a concentrations were not significant predictors of elk calf survival through 21 …

Use Of Implanted Radiotransmitters To Estimate Survival Of Greater Sage-Grouse Chicks, Michael A. Gregg, Mike R. Dunbar, John A. Crawford Apr 2007

Use Of Implanted Radiotransmitters To Estimate Survival Of Greater Sage-Grouse Chicks, Michael A. Gregg, Mike R. Dunbar, John A. Crawford

United States Department of Agriculture Wildlife Services: Staff Publications

Reduced chick survival has been implicated in declines of greater sage-grouse (Centrocercus urophasianus) populations. Because monitoring survival of unmarked sage-grouse chicks is difficult, radiotelemetry may be an effective technique to estimate survival rates, identify causes of mortality, and collect ecological data. Previous studies have used subcutaneous implants to attach radiotransmitters to hatchlings of several species of birds with precocial young. Previous researchers who used subcutaneous implants in free-ranging populations removed chicks from the capture location and implanted transmitters at an alternate site. Because logistics precluded removing newly hatched greater sagegrouse chicks from the field, we evaluated a method for implanting …


Coyote Investigative Behavior Following Removal Of Novel Stimuli, Daniel J. Heffernan, William F. Andelt, John A. Shivik Apr 2007

Coyote Investigative Behavior Following Removal Of Novel Stimuli, Daniel J. Heffernan, William F. Andelt, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Because coyotes (Canis latrans) show an aversion to novel objects, we examined the effects of the presence and removal of repellent and attractive stimuli on coyote behavior. We found a greater proportion of captive coyotes investigated 10-cm-tall cones (0.95) compared to 90-cm-tall cones (0.68) and control sites (0.81), and spent longer periods (P , 0.001 in all instances) investigating small cones (x̅ = 465 sec), compared to large cones (x̅ = 212 sec) and control sites (x̅ = 45 sec). However, investigation times at sites following removal of large cones were 1.6 and 2.3 times …

Tertiary Education For Sustainability: Four Australian Universities’ Commitment To Sustainability, Meredith Wilensky

Independent Study Project (ISP) Collection

With increasing evidence of issues such as global climate change and environmental degradation, the need for sustainable development has become evident. While achieving sustainability will require many approaches, there is an immense body of literature, declarations and charters supporting education as key. Tertiary education is particularly important because universities are training our future leaders and professionals. For this reason, universities have a moral responsibility to prepare to work toward achieving a sustainable world. Unfortunately, integrating sustainability education is complex, requiring a paradigm shift toward collaboration, interdisciplinary education and an action-oriented approach.

This study analyzed the extent to and manner in …

Ecosystem-Based Fishery Management In South Australia And Victoria, Rebecca Devries Apr 2007

Ecosystem-Based Fishery Management In South Australia And Victoria, Rebecca Devries

Independent Study Project (ISP) Collection

The detrimental impact from fishing on various species as well as on the overall ecosystem has increased so much over the years that the Australian fishing industry is currently in jeapordy. Scientists, fishery managers, government agencies, industry, and environmental organizations have therefore been actively developing and researching management strategies focused on finding a balance between fisheries and the ecosystem. A new holistic and promising approach, ecosystem-based fishery management, invested in ecological sustainability and the recognition of the critical interdependence between human well-being and ecological health, is currently proposed as the best solution for fishery management.

This paper will consequently investigate …

This draft strategy was developed by the Department of Fisheries, Western Australia, hereafter known as the “Department of Fisheries” which has responsibility for managing fish resources (within Territorial waters out to 12 nautical miles) on behalf of the Commonwealth Department of Transport and Regional Services (DoTARS), through the applied Fish Resources Management Act (FRMA) (WA)(CI) (the “Applied Act”). The Applied Act provides a legislative framework that allows for management arrangements to be developed specifically for Christmas Island. The management of fisheries in Western Australia uses an adaptive approach which balances the need for the effective management of fish stocks with …


Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt Apr 2007

Ecology Of Coyotes In Urban Landscapes, Stanley D. Gehrt

Wildlife Damage Management Conference Proceedings

Coyotes (Canis latrans) have become common in many metropolitan areas across the United States. Recent research has focused on the urban ecology of coyotes to better our understanding of how they exist in urbanized landscapes. I summarize findings from a variety of ecological studies of coyotes in or near metropolitan areas, and focus on three areas of coyote ecology: survival rates, home range/activity, and food habits. Most studies have reported relatively high survival rates (annual S = 0.62 - 0.74), with vehicle collisions often a common cause of mortality. Size of coyote home ranges (mean home range sizes …


Suitable And Effective Coyote Control Tools For The Urban/Suburban Setting, Alan A. Huot, David L. Bergman Apr 2007

Suitable And Effective Coyote Control Tools For The Urban/Suburban Setting, Alan A. Huot, David L. Bergman

Wildlife Damage Management Conference Proceedings

Increases in the incidence of human conflict with coyotes in urban/suburban environments fuel a need for suitable coyote tools and methods to reduce these conflicts. Traditional tools, such as foothold traps and snares, face continued problems of acceptability in urban/suburban situations because of public anxiety about the risks to non-targets as well as other animal welfare concerns. We review the major categories of methods and tools used to prevent or reduce urban coyote-human conflicts, including exclusion (fencing), environmental and habitat modification, capture devices (traps, snares, and related devices), and shooting. We briefly discuss future technologies current under development: fertility control, …
