Mitigating Wind Energy Impacts On Wildlife: Approaches For Multiple Taxa, Edward B. Arnett, Roel F. May

Human–Wildlife Interactions

Mitigating impacts of wind energy development on wildlife is important for conservation and public acceptance of this energy source. We provide an overview of approaches to mitigate impacts of onshore wind energy development on wildlife, following steps in the mitigation hierarchy, including avoidance, minimization, and compensatory mitigation. Planning and avoiding predicted high-risk areas is fundamental to reduce impacts on birds and bats. Contrary to avoidance, once facilities are built, options to minimize impacts need to be tailored to species at the specifc site, and can be limited especially for bats. Curtailing wind turbine operations is the only approach proven effective …

Adapting Strategies To Maintain Efficiency During A Cull Of Yellow-Legged Gulls, Sugoto Roy, Ray Ridley, Jeff Sandon, John R. Allan, Peter S. Robertson, Andrew Baxter

Human–Wildlife Interactions

Increasing populations of yellow-legged gulls (Larus michahellis) in the Mediterranean have created conflicts with seabird conservation, migrating raptors, and humans. As a mitigation measure, gulls are routinely culled in the region. Previous studies of extended culls show that catch per unit effort declines over time through a combination of population reductions and avoidance behaviors developing within the remaining population. We countered these problems during a 4-year cull of yellow-legged gulls in Gibraltar by matching the type and mode of deployment of firearms in response to changes in gull distribution and behavior. We found that shotguns were effective when …

Impacts Of Coyote Removal On Space Use By Greater Sage-Grouse, Elizabeth K. Orning, Julie K. Young

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus) are in decline across western North America. Identification of management strategies to enhance populations, such as predator management, may be needed to reduce further declines, but unintentional effects associated with increased human activity should also be considered. We evaluated the effect of 3 levels of predator management effort on greater sage-grouse space use. Home range size, movement rate, seasonal movement timing, and inter-seasonal distances traveled were examined as behavioral responses relative to levels of coyote removal in Bighorn Basin, Wyoming. We observed larger home range sizes during brood-rearing but overall smaller annual core (25% …

Commentary Distance-Dependent Effectiveness Of Diversionary Bear Bait Sites, Stephen Stringham, Ann Bryant

Human–Wildlife Interactions

We (Stringham and Bryant 2015) previously reported on Bryant’s experiment in diversionary baiting of black bears (Ursus americanus). This occurred during the historically severe drought of 2007, in the Lake Tahoe Basin at the border of California and Nevada, USA. Effectiveness of baiting was inversely related to each community’s distance from the bait site. That has provoked the question whether conflict rates during the period of baiting would have fallen anyway even without baiting. We show here that the general trend during both pre and post-baiting years (2005–2006 and 2008–2009) was for an increase in conflicts during the …

Impact Of Sagebrush Nutrients And Monoterpenes On Greater Sage-Grouse Vital Rates, Brian R. Wing, Terry A. Messmer

Human–Wildlife Interactions

Greater sage-grouse (Centrocercus urophasianus; sage-grouse) depend on sagebrush (Artemisia spp.) to complete its annual life cycle. The winter diet for sage-grouse consists almost entirely of sagebrush leaves, and individual birds may gain weight while foraging on sagebrush. Previous studies have reported higher crude protein and lower monoterpene concentrations in the sagebrush species selected as winter forage by sagegrouse. However, no studies have attempted to link female sage-grouse vital rates (i.e., nest initiation and success, egg fertility, clutch size, and adult survival) to crude protein or monoterpene concentrations of sagebrush plants browsed during pre-nesting periods. From March …

Grizzly Bear Space Use, Survival, And Persistence In Relation To Human Habitation And Access, Bogdan Cristescu, Gordon B. Stenhouse, Bernie Goski, Mark S. Boyce

Human–Wildlife Interactions

Previous studies showed that the likelihood of a bear becoming a nuisance and thus being removed from a population (i.e., relocated or killed) depends on numerous factors such as natural food supply, sex, age, and reproductive status. Distances from a bear’s home range and activity centers to conflict zones such as towns, roads, and trails used by humans also affect the incidence of nuisance behavior and have been documented for grizzly/brown bears (Ursus arctos) in North America and Europe. But those studies did not quantify the relative influences by various factors on distance from conflict zones, or the …

Short-Term Fate Of Rehabilitated Orphan Black Bears Released In New Hampshire, Wesley E. Smith, Peter J. Pekins, Andrew A. Timmins, Benjamin Kilham

Human–Wildlife Interactions

We evaluated the release of rehabilitated, orphan black bears (Ursus americanus) in northern New Hampshire. Eleven bears (9 males, 2 females; 40–45 kg) were outfitted with GPS radio-collars and released during May and June of 2011 and 2012. Bears released in 2011 had higher apparent survival and were not observed or reported in any nuisance behavior, whereas no bears released in 2012 survived, and all were involved in minor nuisance behavior. Analysis of GPS locations indicated that bears in 2011 had access to and used abundant natural forages or habitat. Conversely, abundance of soft and hard mast was …

Use Of Predator Hair To Enhance Perceived Risk To White-Tailed Deer In A Foraging Context, Thomas W. Seamans, Bradley F. Blackwell, Kimberly E. Linnell

Human–Wildlife Interactions

Deer react to predator scent in varying degrees even when exposed to unknown predators. This response could be genetically based and maintained as long as the population is exposed to predation. We tested whether predator scent in the form of hair would enhance perceived risk and serve as a foraging repellent to free-ranging white-tailed deer (Odocoileus virginianus). During the winters of 2013 and 2014, we quantified alert behaviors and consumption of whole-kernel corn in response to current (coyote [Canis latrans]) and extirpated (bobcat [Lynx rufus]; black bear [Ursus americanus]) predator species alone …

Economic Utility For The Anthropogenic Spread Of Wild Hogs, Joe N. Caudell, Emily Dowell, Katelyn Welch

Human–Wildlife Interactions

Wild hogs (Sus scrofa) are an invasive, exotic species that has spread through much of the United States through anthropogenic means. Many states have laws and regulations with the intent of preventing the illegal importation, introduction, and establishment of wild swine populations. However, in many cases, these laws have been ineffectual at stopping the anthropogenic spread of wild swine. To assess the risk for moving wild hogs, we examined various wild hog-related laws throughout the United States and assessed the potential reward for their illegal movement of releasing hogs for hunting purposes. We found that fines ranged from …

Influence Of Transmission Line Construction On Winter Sage-Grouse Habitat Use In Southern Utah, Erica P. Hansen, A. Cheyenne Stewart, S. Nicole Frey

Human–Wildlife Interactions

The construction and operation of electric power transmission lines (“power lines”) and their associated infrastructure has been identified as a conservation threat to the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The conservation buff er zones recommended by state and federal agencies to avoid potential impacts on breeding populations diff er because information regarding the effects of power lines on sage-grouse is lacking. Little information is available regarding sage-grouse responses to power lines placed in winter habitat. Hence, we evaluated sage-grouse habitat use before and after construction of the Sigurd-Red Butte (SRB) 345-kilovolt (kV) transmission line in winter habitat. The …

Efficacy Of Non-Lead Ammunition For Culling Elk At Theodore Roosevelt National Park, Blake E. Mccann, William Whitworth, Robert A. Newman

Human–Wildlife Interactions

During 2010 to 2013, park staff and public volunteers culled 983 elk (Cervus elaphus) from Theodore Roosevelt National Park (United States) utilizing non-lead rifle ammunition as part of a sanctioned herd management operation. Because there is little empirical evidence available on the performance of non-lead ammunition, staff recorded information on tools and techniques relevant to the scenarios under which elk were culled and the outcome of each engagement. We also conducted a fi ring range experiment to evaluate the precision of nonlead ammunition used in park fi rearms. Specific objectives were to identify program factors predicting efficient destruction …

Declining Populations Of Greater Sage-Grouse: Where And Why, Michael R. Conover, Anthony J. Roberts

Human–Wildlife Interactions

Scientists have been predicting the extinction of greater sage-grouse (Centrocercus urophasianus) since 1916, and sage-grouse populations have declined relentlessly during the last century despite attempts to reverse the decline. In this review paper, we examined the scientific literature to evaluate hypotheses about why sage-grouse populations have declined. There is little support for the hypotheses that the decline is due to overhunting, parasites, food shortages, or collisions with power lines or fences. West Nile Virus (WNV) reduced sagegrouse up to 25% when the virus first reached the West during 2002, but sage-grouse have developed resistance to the virus since …

Portmanteau Ascendant: Post-Release Regulations And Sex Offender Recidivism, J. J. Prescott

Articles

The purported purpose of sex offender post-release regulations (e.g., community notification and residency restrictions) is the reduction of sex offender recidivism. On their face, these laws seem well-designed and likely to be effective. A simple economic framework of offender behavior can be used to formalize these basic intuitions: in essence, post-release regulations either increase the probability of detection or increase the immediate cost of engaging in the prohibited activity (or both), and so should reduce the likelihood of criminal behavior. These laws aim to incapacitate people outside of prison. Yet, empirical researchers to date have found essentially no reliable evidence …

Spanish River Carbonatite: Its Benefits And Potential Use As A Soil Supplement In Agriculture, James J

Theses and Dissertations (Comprehensive)

A critical problem facing agriculture today is being able to consistently and sustainably provide plants with adequate nutrients for growth. With this problem being exacerbated by the ever-increasing human population, new perspectives and techniques are required to ensure global food security. In order to fully realize potential solutions, however, plant growth and nutrition cannot be exclusively focused upon. The soil-microorganism-plant system is comprised of many interconnected and interdependent processes that together support plant growth: it is upon these processes that the focus must be placed. In this work, the agromineral Spanish River Carbonatite (SRC) is characterized using the framework of …

Sm And Dy Interaction With Dissolved Organic Matter (Dom) In Freshwater Measured By Ion-Selective Electrode And Fluorescence Quenching Analytical Techniques, Alexandra Carvajal

Theses and Dissertations (Comprehensive)

With the increased demand for lanthanide metals in various industries, companies are looking into mining of these metals in Northern Canada. The release of these metals into the environment may have adverse effect on aquatic ecosystems; thus, it is important to understand potential toxicological effects of lanthanides on aquatic organisms. One way to predict these effects is by using a Biotic Ligand Model (BLM). Although incorporation of lanthanides into the model will require a substantial amount of future research, initial studies into speciation and toxicity can provide a useful basis for future reference. There are two main objectives to this …

Grassroots Consumption: Ontario Farm Families’ Consumption Practices, 1900-45, Andrea M. Gal

Theses and Dissertations (Comprehensive)

Popular culture and academic perceptions typically view farmers of the past in one of two ways. On the one hand, we tend to emphasize their roles as producers of agricultural commodities, and marginalize or underemphasize their roles as consumers. On the other, we might believe that farmers were simply the passive recipients of broader societal trends and developments, and think that they followed in the footsteps of their urban counterparts. A small but growing number of scholars are engaging with these views, as they examine the consumption practices of rural North America. This historiography, however, is largely centered in the …

Changes In Brain Water Content In The Rainbow Trout (Oncorhynchus Mykiss) And In The Goldfish (Carassius Auratus) Due To High External Ammonia Exposure, Phillip Q.H. Pham-Ho

Theses and Dissertations (Comprehensive)

In fishes, hyperammonemia may occur following feeding or exposure to abnormally high concentrations of environmental ammonia due to sewage effluents, agricultural run-off and in crowded aquaculture pens. Increased internal ammonia can result in hyperactivity, convulsions, coma and death. In mammals, it is also associated with potentially fatal brain edema, in which the accumulation of intracellular water results in swelling, increased intracranical pressure and herniation leading to death. Recently it was shown that rainbow trout (Oncorhynchus mykiss) and goldfish (Carassius auratus) experience brain swelling following exposure to high external ammonia (HEA). However, the mechanism of ammonia-induced brain …

The Bigger Picture: Piecing Together The Experiences Of Family Members Living With High-Functioning Children With Autism Spectrum Disorder, Lauren Thomson

Theses and Dissertations (Comprehensive)

The purpose of this research was to explore the experiences of family members living with a child with ASD. The specific research questions that were addressed included: 1. How is a family member affected by having a child with ASD in the family unit; and 2. How does living with a child with ASD affect family functioning? The theoretical orientation of phenomenology was used to guide this research and to allow the “voice” of family members of children with ASD to be heard. The purpose of phenomenology is to distill individuals’ experiences with a phenomenon down to an “essence” of …

Multi-Criteria Decision Analysis (Mcda) For Agricultural Sustainability Assessment, Byomkesh Talukder

Theses and Dissertations (Comprehensive)

Multi Attribute Utility Theory (MAUT), Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) and Elimination methods of Multi-Criteria Decision analysis (MCDA) are tested to assess and compare the sustainability of different agricultural systems. Indicators and composite indicators are derived from data gathered using the agricultural sustainability categories of Productivity, Stability, Efficiency, Durability, Compatibility and Equity (PSEDCE).

Agricultural systems around the world face challenges from current agricultural practices, over-exploitation of natural resources, population growth and climate change. As a result, understanding agricultural sustainability has become a global issue. Assessment is a first step in benchmarking and tracking agricultural sustainability and …

Causes And Consequences Of Variation In Female Mate Choice And Its Relation To Sexual Conflict In Drosophila Melanogaster, David Cs Filice

Theses and Dissertations (Comprehensive)

Female mate choice is a significant driving force of evolutionary change and can explain the evolution of exaggerated male traits and/or displays, and dimorphism between the sexes. Females are thought to choose mates based on the greatest provision of direct or indirect benefits. Despite this, we often still see substantial individual variation in female mate choice behaviours both within and across populations. Recent studies suggest that female mate choice is a complex decision-making process that involves many context-dependent factors. However, the precise sources of this variation, such as previous mating experience, are not completely understood. In Drosophila melanogaster, mating …

The Effect Of Menstrual Cycle Phase On Appetite-Regulating Hormones, Logan Townsend

Theses and Dissertations (Comprehensive)

Background: Obesity rates are higher among females than males potentially due to changing food intake across the menstrual cycle. Food intake is partially regulated by circulating appetite-regulating hormones that can be influenced by the menstrual hormones estradiol and progesterone. Purpose: Examine whether changes in female sex hormones across the menstrual cycle are related to appetite-regulating hormones. Methods: 8 healthy young females were tested during the follicular, ovulatory, and luteal phases; phases were confirmed by fasting plasma hormone concentrations. Blood samples were taken after an overnight fast, as well as 30, 60, and 90 min post-prandially to test the concentrations of …

The Influence Of Hip Mobility And Fatigue On Spinal Flexion And Muscle Activation In Rugby Scrum Performance, Joshua D. Clayton

Theses and Dissertations (Comprehensive)

Introduction: Rugby scrumming is a means of restarting play following a minor rule infringement that can occur up to 28 times per game. The scrum poses a significant injury risk, with more days missed due to injury per event than any other rugby activity. Rugby players also have a significantly higher rate of spine injury than the general population, perhaps due to flexion in combination with high compression forces, which has been cited as the main mechanism of injury. Flexion of the spine has also been associated with poor hip mobility and quadriceps fatigue in other athletic tasks and may …

Spectral And Chromatographic Characterisation Of The Onoceroid, Ambrane: A Potential Novel Biological Marker, Paul A. Sutton, Steven J. Rowland

School of Geography, Earth and Environmental Sciences

The gas chromatography–mass spectrometry (GC–MS) characteristics, including GC retention indices and mass spectra, of isomers of the tricyclic onoceroid C30 hydrocarbon, ambrane (1,1,4a,6-tetramethyl-5-{4-methyl-6-[2,2,6-trimethylcyclohexyl]hexyl}decahydronaphthalene) are reported. Ambrane is yet to be reported in sediments or petroleum: other biochemically-related onoceroids, such as onoceranes and serratanes, have been. Now that GC–MS data are available, a search for ambranes in geochemical samples may be both feasible and warranted.

Subjective Well-Being Among Malaysian Students, Mazni Mustapha

School of Psychology Theses

The aim of the study was to examine the determinants of well-being in Malaysian students at home and overseas. Prior to the main study, interviews were conducted with seven PhD students of Malaysia studying in Plymouth, to explore their needs and values, and their adaptation experiences in terms of missing and enjoyment experiences abroad. Based on the interview findings and literature reviews, a questionnaire was developed and named as the Adaptation to Life Index, which consisted of two scales - ‘missing experience’ and ‘enjoyment experience’. A longitudinal survey was carried out using Malaysian students in the UK, Australia, New Zealand, …
