Design Standards Within Constructed Wetlands For The Reduction Of Mosquito Populations In Clark County, Nevada, Phillip C. Bondurant
Design Standards Within Constructed Wetlands For The Reduction Of Mosquito Populations In Clark County, Nevada, Phillip C. Bondurant
UNLV Theses, Dissertations, Professional Papers, and Capstones
Wetlands are considered one of the most productive ecosystems in the world and provide many benefits to the environment. However, the slow moving and sometimes stagnant water created by the vegetation in the wetland creates an ideal environment for the proliferation of mosquitoes. Mosquitoes are the most important insect disease vector worldwide. The presence of mosquitoes within wetlands increases the risk of disease transmission among workers and visitors creating a public health concern. Effective design standards aimed at reducing mosquito breeding habitat should be implemented during the construction and planning phase of wetland development to effectively reduce the mosquito populations. …

Assessing Linkages Among Landscape Characteristics, Stream Habitat, And Macroinvertebrate Communities In The Idaho Batholith Ecoregion, Andrew C. Hill
Assessing Linkages Among Landscape Characteristics, Stream Habitat, And Macroinvertebrate Communities In The Idaho Batholith Ecoregion, Andrew C. Hill
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Understanding the composition of lotic communities and the landscape processes and habitat characteristics that shape them is one of the main challenges confronting stream ecologists. In order to better understand the linkages among landscape processes, stream habitat, and biological communities and to understand how accurately our measurements represent important factors influencing biological communities, it is important to test explicit hypotheses regarding these linkages. Increasing our understanding of aquatic communities in a hierarchical context and recognizing how well our measurements represent factors structuring aquatic communities will help managers better evaluate the influence of land management practices on aquatic ecosystems, direct conservation …

Vocal Learning In Grey Parrots: A Brief Review Of Perception, Production, And Cross-Species Comparisons, Irene M. Pepperberg
Vocal Learning In Grey Parrots: A Brief Review Of Perception, Production, And Cross-Species Comparisons, Irene M. Pepperberg
Sentience Collection
This chapter briefly reviews what is known—and what remains to be understood—about Grey parrot vocal learning. I review Greys’ physical capacities—issues of auditory perception and production—then discuss how these capacities are used in vocal learning and can be recruited for referential communication with humans. I discuss cross-species comparisons where applicable and conclude with a description of recent research that integrates issues of reference, production and perception.

Farm Animal Welfare Collection
The objective of this study was to evaluate the effects of claw horn disruption lesions (CHDL; sole ulcers and white line disease) and body condition score (BCS) at dry-off on survivability, milk production, and reproductive performance during the subsequent lactation. An observational prospective cohort study was conducted on a large commercial dairy in Cayuga County, New York, from September 2008 until January 2009. A total of 573 cows enrolled at dry-off were scored for body condition and hoof trimmed; digits were visually inspected for the presence of CHDL. The BCS data were recategorized into a 3-level variable BCS group (BCSG), …

Capuchins (Cebus Apella) Can Solve A Means-End Problem, Anna M. Yocom, Sarah T. Boysen
Sentience Collection
Three capuchin monkeys (Cebus apella) were tested on a 2-choice discrimination task designed to examine their knowledge of support, modeled after Hauser, Kralik, and Botto-Mahan’s (1999) experiments with tamarins. This task involved a choice between 2 pieces of cloth, including 1 with a food reward placed on its surface, and a second cloth with the food reward next to its surface. After reliably solving the basic problem, the capuchins were tested with various alternations of the original food reward and cloth. The capuchins were able to solve the initial task quickly, and generalize their knowledge to additional functional and nonfunctional …

Information Acquisition And Sociality Among Migratory Birds, Zoltán Németh
Information Acquisition And Sociality Among Migratory Birds, Zoltán Németh
Dissertations
Information use is a key feature of adaptive behavior: the better informed an individual, the better it is able to adjust its behavior to meet the demands of a variable world. Therefore, most animals attempt to reduce environmental uncertainty by gathering information when it is available. However, tracking unpredictable ecological factors may carry costs as individuals invest valuable time and energy in the process of information acquisition. Social learning (i.e., use of social information inadvertently produced by other individuals) enables the individual to gain rapid and more complete assessment of its novel environment. This process may be particularly important for …
Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul Mcgreevy, Michael Valenzuela
Human Induced Rotation And Reorganization Of The Brain Of Domestic Dogs, Taryn Roberts, Paul Mcgreevy, Michael Valenzuela
Morphology Collection
Domestic dogs exhibit an extraordinary degree of morphological diversity. Such breed-to-breed variability applies equally to the canine skull, however little is known about whether this translates to systematic differences in cerebral organization. By looking at the paramedian sagittal magnetic resonance image slice of canine brains across a range of animals with different skull shapes (N = 13), we found that the relative reduction in skull length compared to width (measured by Cephalic Index) was significantly correlated to a progressive ventral pitching of the primary longitudinal brain axis (r = 0.83), as well as with a ventral shift in the position …
Dairy Farmer Attitudes And Empathy Toward Animals Are Associated With Animal Welfare Indicators, Camilla Kielland, Eystein Skjerve, Olav Østerås, Adroaldo José Zanella
Dairy Farmer Attitudes And Empathy Toward Animals Are Associated With Animal Welfare Indicators, Camilla Kielland, Eystein Skjerve, Olav Østerås, Adroaldo José Zanella
Societal Attitudes Toward Animals Collection
Attitudes and empathy of farmers influence human–animal interaction, thereby affecting their behavior toward animals. The goal was to investigate how measures of attitude and empathy toward animals were associated with animal welfare indicators such as milk yield, mastitis incidence, fertility index, and the prevalence of skin lesions on cows. To assess empathy toward animals, a photo-based pain assessment instrument was developed depicting various conditions that could be associated with some degree of pain in cattle and included questions aimed at assessing attitudes toward animals. Photos of painful conditions are useful in eliciting measurable empathic responses to pain in humans. A …
Animal-Human Relationships In Child Protective Services: Getting A Baseline, Lisa Anne Zilney, Christina Risley-Curtiss, Rebecca Hornung
Animal-Human Relationships In Child Protective Services: Getting A Baseline, Lisa Anne Zilney, Christina Risley-Curtiss, Rebecca Hornung
Department of Justice Studies Faculty Scholarship and Creative Works
The inclusion of certain aspects of animal-human relationships (AHR), such as animal abuse and animal-assisted interventions, can enhance child welfare practice and there are resources available to promote such inclusion. However, there is little knowledge of whether this is being accomplished. This study sought to fill this gap by conducting a national survey of state public child welfare agencies to examine AHR in child protective services practice, their assessment tools, and cross-reporting policies.

Basking Behavior Of Emydid Turtles (Chysemys Picta Marginata, Graptemys Geographica, And Trachemys Scripta Elegans) In An Urban Landscape, W. Peterman, Travis Ryan
Travis J. Ryan
Basking is common in emydid turtles and is generally accepted to be in thermoregulatory behavior. In 2004, we quantified and described the basking behavior of turtles in the Central Canal of Indianapolis. This canal system runs through an urban landscape that is dominated by fragmented woodlots, residential areas. and commercial areas. We observed that basking turtles exhibited variable basking behavior. with spatial and temporal shins in basking behavior from east-facing banks in the morning to west-facing banks in the afternoon. Turtles in the Central Canal are subject to frequent disturbance, which altered basking behavior. Many turtles forewent aerial basking on …

Design, Planning, And Evaluation Of Upgraded Cattle Handling Facility, Lindsey Kaeli Tulloch
BioResource and Agricultural Engineering
This senior project discusses the design, planning, and evaluation of a livestock handling facility for Tulloch Ranches. The facility will be an upgrade to the facility currently used at the ranch in Pine Valley, California. The design parameters for the facility were narrowed down to the following: 1. Must reduce stress to animals during handling. 2. Must be cost effective to save labor and maintenance. 3. Must show improvement from the current set- up. The above parameters combine to form a system that enables the handlers of Tulloch Ranches to manage and work cattle in a more calm and humane …

On-Farm Welfare Assessment For Regulatory Purposes: Issues And Possible Solutions, Jan Tind Sørensen, David Fraser
Assessment of Animal Welfare Collection
On-farm welfare assessment has been used mainly for non-regulatory purposes such as producer education or to qualify for voluntary welfare-assurance programs. The application of on-farm assessments in regulatory programs would require four issues to be addressed: (1) selecting criteria that are widely accepted as valid by diverse citizens, (2) setting minimum legal levels, (3) achieving the high level of fairness and objectivity required for legally binding requirements, and (4) achieving the cost-efficiency needed for widespread use of the methods. Issues 1 and 2 pose a particular problem because different citizens disagree on what they understand as good animal welfare, with …
Lidar Remote Sensing Variables Predict Breeding Habitat Of A Neotropical Migrant Bird, Scott J. Goetz, Daniel Steinberg, Matthew G. G. Betts, Richard T. Holmes
Lidar Remote Sensing Variables Predict Breeding Habitat Of A Neotropical Migrant Bird, Scott J. Goetz, Daniel Steinberg, Matthew G. G. Betts, Richard T. Holmes
Dartmouth Scholarship
A topic of recurring interest in ecological research is the degree to which vegetation structure influences the distribution and abundance of species. Here we test the applicability of remote sensing, particularly novel use of waveform lidar measurements, for quantifying the habitat heterogeneity of a contiguous northern hardwoods forest in the northeastern United States. We apply these results to predict the breeding habitat quality, an indicator of reproductive output of a well-studied Neotropical migrant songbird, the Black-throated Blue Warbler (Dendroica caerulescens). We found that using canopy vertical structure metrics provided unique information for models of habitat quality and spatial patterns of …

Your Attention Please: Increasing Ambient Noise Levels Elicits A Change In Communication Behaviour In Humpback Whales (Megaptera Novaeangliae), Rebecca A. Dunlop, Douglas H. Cato, Michael J. Noad
Bioacoustics Collection
High background noise is an important obstacle in successful signal detection and perception of an intended acoustic signal. To overcome this problem, many animals modify their acoustic signal by increasing the repetition rate, duration, amplitude or frequency range of the signal. An alternative method to ensure successful signal reception, yet to be tested in animals, involves the use of two different types of signal, where one signal type may enhance the other in periods of high background noise. Humpback whale communication signals comprise two different types: vocal signals, and surface-generated signals such as ‘breaching’ or ‘pectoral slapping’. We found that …

Participatory Rural Appraisal, Ganesh Chandra
Participatory Rural Appraisal, Ganesh Chandra
Ganesh Chandra
Participation, empowerment and inclusion have become the new development buzzword. There has been a range of interpretations of the meaning of participation in development. Participatory development starts from the premise that it is important to identify and build upon strengths already present in communities. Perhaps the most widespread appearance of participation in mainstream development has been seen in the form of participatory methodologies of research, intended to gather a wide range of information from local people at their livelihoods, needs, and strengths, at the same time as 'empowering' them through a process of collaborative analysis and learning. PRA is a …
Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra
Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra
Ganesh Chandra
Flow of communication and information from the research station to the end user is sine qua non for the sustainable production as well as productivity enhancement in inland fisheries and the development of fishers as a whole. The resource poor who are often more in need than others of information on sustainable and low external input technologies is least likely to gain access to the information required. This has been seen particularly in the fisheries sector where the channels of information accessible to the resource poor delivered information on new practices and recommendations as well as the new culture technologies, …

Non-Invasive Genetic Sampling Of Faecal Material And Hair From The Grey-Headed Flying-Fox (Pteropus Poliocephalus), Heather J. Baldwin, Stephen J. Hoggard, Stephanie T. Snoyman, Adam J. Snow, Culum Brown
Veterinary Science and Medicine Collection
Remote-sampling DNA from animals offers obvious benefits for species that are difficult to sample directly and is less disruptive for species of conservation concern. Here we report the results of a pilot study investigating non-invasive DNA sampling of the grey-headed flying-fox (Pteropus poliocephalus), a threatened species that is restricted to the east coast of Australia. We successfully extracted DNA from fresh scats and hair, each of which was of sufficient quality for amplifying mitochondrial DNA markers and microsatellites. A single-locus multitube approach was used to investigate amplification success and genotyping reliability. Faecal samples yielded a higher proportion of successful amplifications …

Changes In Area Affect Figure–Ground Assignment In Pigeons, Leyre Castro, Olga F. Lazareva, Shaun P. Vecera, Edward A. Wasserman
Perception Collection
A critical cue for figure–ground assignment in humans is area: smaller regions are more likely to be perceived as figures than are larger regions. To see if pigeons are similarly sensitive to this cue, we trained birds to report whether a target appeared on a colored figure or on a differently colored background. The initial training figure was either smaller than (Experiments 1 and 2) or the same area as (Experiment 2) the background. After training, we increased or decreased the size of the figure. When the original training shape was smaller than the background, pigeons’ performance improved with smaller …

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur
Scholarship and Professional Work - LAS
We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …
