The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans Jan 2015

The Impacts Of Climate Change Mitigation Strategies On Animal Welfare, Sara Shields, Geoffrey Orme-Evans

Animal Welfare Collection

The objective of this review is to point out that the global dialog on reducing greenhouse gas emissions in animal agriculture has, thus far, not adequately considered animal welfare in proposed climate change mitigation strategies. Many suggested approaches for reducing emissions, most of which could generally be described as calls for the intensification of production, can have substantial effects on the animals. Given the growing world-wide awareness and concern for animal welfare, many of these approaches are not socially sustainable. This review identifies the main emission abatement strategies in the climate change literature that would negatively affect animal welfare and …


Thinking Pigs: A Comparative Review Of Cognition, Emotion, And Personality In Sus Domesticus, Lori Marino, Christina M. Colvin Jan 2015

Thinking Pigs: A Comparative Review Of Cognition, Emotion, And Personality In Sus Domesticus, Lori Marino, Christina M. Colvin

Sentience Collection

While relatively little is known about the psychology of domestic pigs, what is known suggests that pigs are cognitively complex and share many traits with animals whom we consider intelligent. This paper reviews the scientific evidence for cognitive complexity in domestic pigs and, when appropriate, compares this literature with similar findings in other animals, focusing on some of the more compelling and cutting-edge research results. The goals of this paper are to: 1) frame pig cognition and psychology in a basic comparative context independent of the livestock production and management setting; and 2) identify areas of research with pigs that …


Pain In Aquatic Animals, Lynne U. Sneddon Jan 2015

Pain In Aquatic Animals, Lynne U. Sneddon

Sentience Collection

Recent developments in the study of pain in animals have demonstrated the potential for pain perception in a variety of wholly aquatic species such as molluscs, crustaceans and fish. This allows us to gain insight into how the ecological pressures and differential life history of living in a watery medium can yield novel data that inform the comparative physiology and evolution of pain. Nociception is the simple detection of potentially painful stimuli usually accompanied by a reflex withdrawal response, and nociceptors have been found in aquatic invertebrates such as the sea slug Aplysia. It would seem adaptive to have a …


Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown Jan 2015

Cue Choice And Spatial Learning Ability Are Affected By Habitat Complexity In Intertidal Gobies, Gemma E. White, Culum Brown

Sentience Collection

Variation in the structural complexity of a habitat is known to have significant affects on the evolution of different populations and can shape behavior, morphology, and life-history traits. Here, we investigated whether habitat complexity influences a species’ capacity for spatial learning and cue choice by comparing the performance of 4 goby species from 2 contrasting habitats in a spatial task. Gobies were collected from dynamic, homogenous sandy shores and stable, spatially complex rock pool habitats. We trained fish to use a T-maze to find a hidden reward and asked whether they used local visual landmarks or body-centered methods for orientation …


Fish Intelligence, Sentience And Ethics, Culum Brown Jan 2015

Fish Intelligence, Sentience And Ethics, Culum Brown

Sentience Collection

Fish are one of the most highly utilised vertebrate taxa by humans; they are harvested from wild stocks as part of global fishing industries, grown under intensive aquaculture conditions, are the most common pet and are widely used for scientific research. But fish are seldom afforded the same level of compassion or welfare as warm-blooded vertebrates. Part of the problem is the large gap between people’s perception of fish intelligence and the scientific reality. This is an important issue because public perception guides government policy. The perception of an animal’s intelligence often drives our decision whether or not to include …


The Sensitivity Of Qba Assessments Of Sheep Behavioural Expression To Variations In Visual Or Verbal Information Provided To Observers, P. A. Fleming, S. L. Wickham, C. A. Stockman, E. Verbeek, L. Matthews, F. Wemelsfelder Jan 2015

The Sensitivity Of Qba Assessments Of Sheep Behavioural Expression To Variations In Visual Or Verbal Information Provided To Observers, P. A. Fleming, S. L. Wickham, C. A. Stockman, E. Verbeek, L. Matthews, F. Wemelsfelder

Sentience Collection

Qualitative behavioural assessment (QBA) is based on observers’ ability to capture the dynamic complexity of an animal’s demeanour as it interacts with the environment, in terms such as tense, anxious or relaxed. Sensitivity to context is part of QBA’s integrative capacity and discriminatory power; however, when not properly managed it can also be a source of undesirable variability and bias. This study investigated the sensitivity of QBA to variations in the visual or verbal information provided to observers, using free-choice profiling (FCP) methodology. FCP allows observers to generate their own descriptive terms for animal demeanour, against which each animal’s expressions …


The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott Jan 2015

The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott

Sentience Collection

The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …


Intrasexual Selection Drives Sensitivity To Pitch, Formants And Duration In The Competitive Calls Of Fallow Bucks, Benjamin J. Pitcher, Elodie Briefer, Alan G. Mcelligott Jan 2015

Intrasexual Selection Drives Sensitivity To Pitch, Formants And Duration In The Competitive Calls Of Fallow Bucks, Benjamin J. Pitcher, Elodie Briefer, Alan G. Mcelligott

Ethology Collection

Background: Mammal vocal parameters such as fundamental frequency (or pitch; fo) and formant dispersion often provide information about quality traits of the producer (e.g. dominance and body size), suggesting that they are sexually selected. However, little experimental evidence exists demonstrating the importance of these cues in intrasexual competition, particularly fo. Male Fallow deer (bucks) produce an extremely low pitched groan. Bucks have a descended larynx and generate fo well below what is expected for animals of their size. Groan parameters are linked to caller dominance, body size and condition, suggesting that groans are the product of sexual selection. Using a …


Segregation Of Information About Emotional Arousal And Valence In Horse Whinnies, Elodie F. Briefer, Anne-Laure Maigrot, Roi Mandel, Sabrina Briefer Freymond, Iris Bachmann, Edna Hillmann Jan 2015

Segregation Of Information About Emotional Arousal And Valence In Horse Whinnies, Elodie F. Briefer, Anne-Laure Maigrot, Roi Mandel, Sabrina Briefer Freymond, Iris Bachmann, Edna Hillmann

Sentience Collection

Studying vocal correlates of emotions is important to provide a better understanding of the evolution of emotion expression through cross-species comparisons. Emotions are composed of two main dimensions: emotional arousal (calm versus excited) and valence (negative versus positive). These two dimensions could be encoded in different vocal parameters (segregation of information) or in the same parameters, inducing a trade-off between cues indicating emotional arousal and valence. We investigated these two hypotheses in horses. We placed horses in five situations eliciting several arousal levels and positive as well as negative valence. Physiological and behavioral measures collected during the tests suggested the …


Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff Jan 2015

Compassion As A Practical And Evolved Ethic For Conservation, David Ramp, Marc Bekoff

Conservation Collection

The ethical position underpinning decisionmaking is an important concern for conservation biologists when setting priorities for interventions. The recent debate on how best to protect nature has centered on contrasting intrinsic and aesthetic values against utilitarian and economic values, driven by an inevitable global rise in conservation conflicts. These discussions have primarily been targeted at species and ecosystems for success, without explicitly expressing concern for the intrinsic value and welfare of individual animals. In part, this is because animal welfare has historically been thought of as an impediment to conservation. However, practical implementations of conservation that provide good welfare outcomes …


Predator Recognition And Responses In The Endangered Macquarie Perch (Macquaria Australasica), Culum Brown, Jennifer Morgan Jan 2015

Predator Recognition And Responses In The Endangered Macquarie Perch (Macquaria Australasica), Culum Brown, Jennifer Morgan

Sentience Collection

Macquarie perch, Macquaria austalasica, is an endangered species endemic to southern Australia whose distribution is highly fragmented and continues to decline. Key threatening processes include habitat destruction, dams and weirs, overfishing and interactions with introduced species. Here, we examined the responses of small and large Macquarie perch to two native predators and to the introduced redfin perch, Perca fluviatilis. Our results showed that Macquarie perch generally avoided large-bodied native predators but was attracted to small-bodied native predators. Responses to large and small redfin perch lay between these two extremes, suggesting that the Macquarie perch does treat these foreign fish as …


“Goats That Stare At Men” – Dwarf Goats Alter Their Behaviour In Response To Human Head Orientation But Do Not Spontaneously Use Head Direction As A Cue In A Food-Related Context, Christian Nawroth, Eberhard Von Borell, Jan Langbein Jan 2015

“Goats That Stare At Men” – Dwarf Goats Alter Their Behaviour In Response To Human Head Orientation But Do Not Spontaneously Use Head Direction As A Cue In A Food-Related Context, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Social Cognition Collection

Recently, comparative research on the mechanisms and species-specific adaptive values of attributing attentive states and using communicative cues has gained increased interest, particularly in non-human primates, birds, and dogs. Here, we investigate these phenomena in a farm animal species, the dwarf goat (Capra aegagrus hircus). In the first experiment, we investigated the effects of different human head and body orientations, as well as human experimenter presence/absence, of a human on the behaviour of goats in a food-anticipating paradigm. Over a 30-sec interval, the experimenter engaged in one of four different postures or behaviours (head and body towards the subject, head …


Maintaining Ethical Standards During Conservation Crises, Ryan K. Brook, Mark Cattet, Chris T. Darimont, Paul C. Paquet, Gilbert Proulx Jan 2015

Maintaining Ethical Standards During Conservation Crises, Ryan K. Brook, Mark Cattet, Chris T. Darimont, Paul C. Paquet, Gilbert Proulx

Ethics and Conservation Biology Collection

Many species at risk in Canada and globally are at or approaching a crisis, especially where little or nothing consequential is being done to prevent extirpation. Such is the case of endangered boreal caribou (Rangifer tarandus caribou) in southern Alberta, Canada. Expedient but inadequate emergency ‘fixes’ have been experimentally implemented to arrest their decline and potential extirpation, but use of these measures raises important ethical problems. In their study of the effects of killing wolves (Canis lupus) on the Little Smoky woodland caribou population, Hervieux et al. (2014a) employed lethal methods that included shooting a firearm from a helicopter and …


Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet Jan 2015

Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet

Population Distribution and Habitat Collection

Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out of date and/or highly uncertain. Systematic, line-transect marine mammal surveys were conducted in British Columbia’s (BC) coastal waters over multiple years and seasons (summer 2004, 2005, 2008, and spring/autumn 2007). In total, 10,057km of transects were surveyed in an 83,547km2 study area. Abundance estimates were calculated using two different methods: Conventional Distance Sampling (CDS) and Density Surface Modelling (DSM). CDS generates a single density estimate for each stratum, whereas DSM …


Scent Of The Familiar: An Fmri Study Of Canine Brain Responses To Familiar And Unfamiliar Human And Dog Odors, Gregory S. Berns, Andrew M. Brooks, Mark Spivak Jan 2015

Scent Of The Familiar: An Fmri Study Of Canine Brain Responses To Familiar And Unfamiliar Human And Dog Odors, Gregory S. Berns, Andrew M. Brooks, Mark Spivak

Social Cognition Collection

Understanding dogs’ perceptual experience of both conspecifics and humans is important to understand how dogs evolved and the nature of their relationships with humans and other dogs. Olfaction is believed to be dogs’ most powerful and perhaps important sense and an obvious place to begin for the study of social cognition of conspecifics and humans. We used fMRI in a cohort of dogs (N = 12) that had been trained to remain motionless while unsedated and unrestrained in the MRI. By presenting scents from humans and conspecifics, we aimed to identify the dimensions of dogs’ responses to salient biological …


A General Framework For Animal Density Estimation From Acoustic Detections Across A Fixed Microphone Array, Ben C. Stevenson, David L. Borchers, Res Altwegg, René Swift, Douglas M. Gillespie, G. John Measey Jan 2015

A General Framework For Animal Density Estimation From Acoustic Detections Across A Fixed Microphone Array, Ben C. Stevenson, David L. Borchers, Res Altwegg, René Swift, Douglas M. Gillespie, G. John Measey

Bioacoustics Collection

  1. Acoustic monitoring can be an efficient, cheap, non‐invasive alternative to physical trapping of individuals. Spatially explicit capture–recapture (SECR) methods have been proposed to estimate calling animal abundance and density from data collected by a fixed array of microphones. However, these methods make some assumptions that are unlikely to hold in many situations, and the consequences of violating these are yet to be investigated.
  2. We generalize existing acoustic SECR methodology, enabling these methods to be used in a much wider variety of situations. We incorporate time‐of‐arrival (TOA) data collected by the microphone array, increasing the precision of calling animal density estimates. …

Knowledge Enabled Approach To Predict The Location Of Twitter Users, Revathy Krishnamurthy, Pavan Kapanipathi, Amit P. Sheth, Krishnaprasad Thirunarayan

Kno.e.sis Publications

Knowledge bases have been used to improve performance in applications ranging from web search and event detection to entity recognition and disambiguation. More recently, knowledge bases have been used to analyze social data. A key challenge in social data analysis has been the identification of the geographic location of online users in a social network such as Twitter. Existing approaches to predict the location of users, based on their tweets, rely solely on social media features or probabilistic language models. These approaches are supervised and require large training dataset of geo-tagged tweets to build their models. As most Twitter users …


Mining Behavior Of Citizen Sensor Communities To Improve Cooperation With Organizational Actors, Hemant Purohit Jan 2015

Mining Behavior Of Citizen Sensor Communities To Improve Cooperation With Organizational Actors, Hemant Purohit

Kno.e.sis Publications

Web 2.0 (social media) provides a natural platform for dynamic emergence of citizen (as) sensor communities, where the citizens generate content for sharing information and engaging in discussions. Such a citizen sensor community (CSC) has stated or implied goals that are helpful in the work of formal organizations, such as an emergency management unit, for prioritizing their response needs. This research addresses questions related to design of a cooperative system of organizations and citizens in CSC. Prior research by social scientists in a limited offline and online environment has provided a foundation for research on cooperative behavior challenges, including ‘ …

Division of Research and Economic Development Faculty & Staff Publications

Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US. We find that in addition to taxonomic and metabolic differences between urban and traditional lifestyles, hunter-gatherers form a distinct sub-group among traditional peoples. As observed in previous studies, we find that Treponema are characteristic of traditional gut microbiomes. Moreover, through genome reconstruction (2.2-2.5 MB, coverage depth x26-513) and functional potential …

Coaches Perspective: Changes In Swim Performance And Perceived Stress And Recovery In Female Collegiate Swimmers Across A Competitive Season, Jacquelyn Zera, James Mcmillan, Barry Munkasy, A. Joyner, Stephen Rossi

Exercise Science and Sports Studies

Optimal sport performance involves balancing the accumulation of training stress with adequate recovery (Budgett, 2000; Hollander & Meyers, 1995). Continuous evaluation of an athlete's performance levels, stress levels, and recovery states during a competitive season is important in determining an athlete's readiness for competition. This study's purpose was to examine effects of training load on performance, perceived stress, and recovery among collegiate female athletes across a competitive season. Nineteen NCAA Division I female swimmers completed monthly testing including six tethered swim tests and seven Recovery-Stress Questionnaires (RESTQ-76), yielding mean force (Fmean) and Total Recovery-Stress Score (TRSS). This study's results indicate …

The Use Of Oral History And Narrative Research In Broadening The Historical Foundation Of The Agricultural Communication Field, Natalie L Federer Jan 2015

The Use Of Oral History And Narrative Research In Broadening The Historical Foundation Of The Agricultural Communication Field, Natalie L Federer

Open Access Dissertations

The historical foundation of the agricultural communication community (consisting of both academics and the profession) is shallow and void of humanistic perspective, and there is a minimal amount of historical content that focuses on academic and professional history. The need to explore and interpret historical dimensions of this field is vital to further development of the discipline as an academic and professional field. Oral history was utilized to capture and preserve the interview content from a small sample of agricultural communication and Extension professionals and faculty while narrative research, interpretative theory, and constructivism were utilized to further understand and interpret …

Effects Of Extension Services On The Technical Efficiency Of Rice Farmers In Albay, 2014-2015, Bm Bathan Jan 2015

Effects Of Extension Services On The Technical Efficiency Of Rice Farmers In Albay, 2014-2015, Bm Bathan

Journal of Economics, Management and Agricultural Development

Through the Farmers Information and Technology Services (FITS) program, extension services in the form of trainings and seminars, and education and communication materials were provided to rice farmers in Albay. Using farm-level input-output data covering the wet season of 2014 and the socio-economic and farm-specific characteristics of randomly sampled 30 farmer beneficiaries and 30 non-beneficiaries, a stochastic production function and technical inefficiency model were estimated. Results of the study reveal that beneficiaries have higher input utilization, yield and technical efficiency than non-beneficiaries. Furthermore, the amount of seed and fertilizer significantly and positively affects the yield of rice. In addition, the …

Economic Impacts Of Smallholder Oil Palm (Elaeis Guineensis Jacq.) Plantations On Peatlands In Indonesia, Roberto F. Ranola Jr., Asa Jose Sajise

Journal of Economics, Management and Agricultural Development

Oil palm smallholders on peatlands have contributed significantly to economic development in rural areas by augmenting income and reducing poverty. However, these plantations also cause adverse environmental impacts such as carbon emission, haze and peat fires, deforestation, water supply disruption and biodiversity loss. The objective of the study is to determine the economic impacts of developing smallholder oil palm plantations on peatlands in Siak District Riau Province, Indonesia. Cochran sampling technique was employed to select the respondents. Cost benefit analysis was used to determine the economic impacts of the smallholder oil palm plantations. Results reveal that the development of 94,726 …

Constructing ‘Farmer’ And ‘State’ Identities In Moral Discourses About Semi-Subsistence Agriculture In North-East Brazil, Karen E. Pennesi Jan 2015

Constructing ‘Farmer’ And ‘State’ Identities In Moral Discourses About Semi-Subsistence Agriculture In North-East Brazil, Karen E. Pennesi

Anthropology Publications

Anthropological analysis elucidates how discourses about agriculture in one North-east Brazilian community reflect relational roles of citizens and the state, the position of farmers in society, and the relationship of individuals to their work. In these discourses, farmers are positioned as moral, hard-working, autonomous citizens, justifying their participation in low-paying activities. The declining numbers of agricultural workers is explained as a result of individual laziness or government irresponsibility. In using these discourses to take stances publicly on agricultural issues, speakers assign responsibilities and moral status to agents. In constructing rural identities, such moral discourses emphasise the symbolic value of subsistence …


Alternative Timing Of Carbaryl Treatments For Protecting Lodgepole Pine From Mortality Attributed To Mountain Pine Beetle, Christopher J. Fettig, A Steve Munson, Kenneth E. Gibson Jan 2015

Alternative Timing Of Carbaryl Treatments For Protecting Lodgepole Pine From Mortality Attributed To Mountain Pine Beetle, Christopher J. Fettig, A Steve Munson, Kenneth E. Gibson

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Carbaryl is regarded among the most effective, economically viable, and ecologically-compatible insecticides available for protecting conifers from bark beetle attack in the western United States. Treatments are typically applied in spring prior to initiation of bark beetle flight for that year. We evaluated the efficacy of spring and fall applications for protecting individual lodgepole pine, Pinus contorta Dougl. ex Loud, from mortality attributed to mountain pine beetle, Dendroctonus ponderosae Hopkins, the most notable forest insect pest in western North America. Both spring and fall treatments of 2.0% a.i. carbaryl (Sevin® SL) were efficacious for two field seasons, while results from …
