Demographics and Populations
Street dogs survive on food handouts provided by individuals, or the wider community yet typically receive limited to no veterinary care. They can also carry a variety of zoonotic diseases such as rabies, posing a significant risk to human and dog population health. Dog sterilization is one of the most humane and effective methods available to control street dog populations. Dog sterilization programs, particularly those operating at a large-scale, often face a variety of challenges including limited resources, staffing, and less-than-ideal facilities. Record keeping is often a challenge as well, which can complicate the return of a sterilized dog to …
Pain In Farm Animals, L. U. Sneddon, Michael J. Gentle
Pain In Farm Animals, L. U. Sneddon, Michael J. Gentle
Farm Animal Welfare Collection
This review will address how we can measure pain in farm animals and discuss the major causes of acute pain and also chronically painful conditions, and finally make suggestions for future improvements. Pain is a relatively difficult concept to define since it comprises both a physiological sensory and a psychological or emotional component. Pain is the subjective interpretation of nerve impulses induced by a stimulus that is actually or potentially damaging to tissues. The sensation of pain is a response to a noxious stimulus and should elicit protective motor (e.g. withdrawal reflex, escape) and vegetative responses (e.g. cardiovascular responses, inflammation). …
The Relationship Of Animal Protection Interests To Animal Damage Management: Historic Paths, Contemporary Concerns And The Uncertain Future, John Hadidian
Conservation Biology and Animal Welfare Collection
More than a decade ago Schmidt (1989) called for consideration of animal welfare to become a "firstorder" decision rule in wildlife management concerns, including animal damage control. Although there has been movement in that direction, this clearly has not yet come to pass. This paper takes a brief look at the interests we call animal damage management, animal welfare and protection, animal rights, and environmentalism in order to speculate about their shared concerns and the uncertain future before them. Since animal damage and the management of that damage cannot be abstracted from the environmental context in which they occur, this …

Dc Birdscape: A Program For Monitoring Neotropical Migratory Birds In Washington, Dc, John Sauer, John Hadidian, Sam Droege, Paul Handly, Carolyn Williams, Christopher Swarth, George Didden, Jane Huff
Biogeography and Ecological Opportunity Collection
Urban and suburban habitats often contain a variety of Neotropical migratory birds, but are poorly sampled by programs such as the North American Breeding Bird Survey. DC Birdscape was developed to inventory and monitor birds in Washington, DC. Birds were surveyed using a systematic sample of point counts during 1993-1995. Results indicate that species richness of Neotropical migratory birds varied among land-use categories, and that maximum species richness occurred in parkland habitats. Although DC Birdscape has provided relevant information on bird distribution and species richness, it is unclear whether the information is of sufficient management interest to support its continuation …

The Use Of Animals In Higher Education: Problems, Alternatives, & Recommendations, Jonathan Balcombe
eBooks
Despite recent advances in technology and increasing societal concern for animals, animals continue to be exploited and killed in large numbers so that students can learn about their structure and function. Dissection may not be without its merits from an educational standpoint, if well implemented, but it appears from student surveys that it usually is not. When one considers the associated costs—animal suffering and death in the supply trade, disruption of wild animal populations, messages that tend to undermine rather than reinforce respect for life and concern for others, rising costs of animal carcasses (as compared with alternatives with longer …
Fetal Pig: The High School Dissection Experience, Gracia Barr, Harold A. Herzog
Fetal Pig: The High School Dissection Experience, Gracia Barr, Harold A. Herzog
Education Collection
Using qualitative methods, we observed a series of fetal pig dissection sessions in a high school biology course and interviewed 17 students in the class. The students' responses to dissection varied considerably. Most felt that dissection was a positive experience, but a substantial minority viewed it primarily in negative terms. Almost all the students had some ambivalence about aspects of the fetal pig lab and believed that alternatives should be provided for students who object to the practice. We argue that dissection remains a viable educational tool but should be an optional rather than compulsory component of the curriculum.
A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal
A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal
Sentience Collection
Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental …

Social Mechanisms Enhance Escape Responses In Shoals Of Rainbowfish, Melanotaenia Duboulayi, Culum Brown, Kevin Warburton
Aquaculture Collection
Shoaling behaviour has been shown to provide many benefits to group members. In this study we examined the ability of fish shoals to escape from a novel trawl apparatus. Fish in shoals of 5 found, and escaped through, a hole in the oncoming trawl more quickly than fish in pairs. Fish in the larger shoals displayed a significant decrease in escape latencies over a series of five trawls, providing clear evidence of net avoidance learning, whereas fish in pairs showed no evidence of learning over successive runs. Observations suggested that more information on the location of the escape route was …
Animal Ethics And Animal Welfare Science: Bridging The Two Cultures, David Fraser
Animal Ethics And Animal Welfare Science: Bridging The Two Cultures, David Fraser
Animal Welfare Collection
Since the 1970s, scientists studying animal welfare and philosophers writing about animal ethics have worked toward the common goal of understanding and articulating our proper relationship to animals of other species. However, the two groups approached this task using such different concepts, assumptions, and vocabulary that they functioned as two distinct ‘‘cultures’’ with little mutual understanding or communication. Some of the best known ethical writing created barriers for scientists because it tended (1) to focus only on the level of the individual rather than making some decisions at the level of the population, ecosystem or species, (2) to advocate single …

Scale-Model Comprehension By Chimpanzees (Pan Troglodytes), Valerie A. Kuhlmeier, Sarah T. Boysen, Kimberly L. Mukobi
Sentience Collection
The ability of chimpanzees (Pan troglodytes) to recognize the correspondence between a scale model and its real-world referent was examined. In Experiments 1 and 2, an adult female and a young adult male watched as an experimenter hid a miniature model food in 1 of 4 sites in a scale model. Then, the chimpanzees were given the opportunity to find the real food item that had been hidden in the analogous location in the real room. The female performed significantly above chance, whereas the male performed at chance level. Experiments 3 and 4 tested 5 adult and 2 adolescent chimpanzees …

Overall Animal Welfare Assessment Reviewed. Part 1: Is It Possible?, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz
Assessment of Animal Welfare Collection
Several authors have concluded that scientists should not attempt to perform overall animal welfare assessment (OWA). They argue that scientists have continued to fail to make progress in this area and that value judgements are inherently involved in OWA for which science cannot provide answers. We take a more positive attitude toward OWA and argue that scientists should avoid creating a self-fulfilling prophecy. OWA is necessary for making actual moral and political decisions. Science has already accumulated much relevant information about welfare and this information should be applied in decision making.
The task of OW A is to assess welfare …

Overall Animal Welfare Reviewed. Part 2: Assessment Tables And Schemes, M.B.M. Bracke, J.H.M. Metz, B. M. Spruijt
Assessment of Animal Welfare Collection
In the scientific literature several attempts have been made to systematically assess the overall welfare-status of animals in relation to housing and management. This paper reviews assessment tables and schemes that have been constructed to this end. These tables and schemes have a tabular format that allows an assessment of housing systems using a list of welfare-relevant attributes (properties of the housing system). Rather than identifying deficits, the focus of this review is on finding positive recommendations for the purpose of developing a method for overall welfare assessment (OWA) on a scientific basis. The main recommendation is to use the …

Overall Animal Welfare Reviewed. Part 3: Welfare Assessment Based On Needs And Supported By Expert Opinion, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz
Assessment of Animal Welfare Collection
Welfare concerns what matters to animals from their point of view. What matters to animals is their state of need. Satisfaction and frustration of needs are associated with emotional states, the subjective experience of which directly determines the welfare status of an animal. Because emotional states are difficult to assess, overall welfare assessment (OWA) is best approached as an assessment of needs.
For actual OW A a list of needs must be formulated. Different authors have formulated different lists. From these lists a concept need-list was constructed. For validation the needs-based approach for OWA was discussed in interviews with experts …

Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff
Predicting Flock Vigilance From Simple Passerine Interactions: Modelling With Cellular Automata, David B. Bahr, Marc Bekoff
Ethology Collection
Vigilance in flocks can be described and modelled as a plausible set of local interactions between neighbouring birds. Each bird in the modelled flock chooses to feed or to scan based solely on whether or not its neighbours are feeding or scanning. This simple model has the ability both to reproduce observations that have not been previously explained and to predict flock behaviours that might be confirmed with future field studies. Examples include simulations showing decreased vigilance with increased flock size (as observed in the field), greater time spent scanning when obstacles such as trees are present (as observed) and …
Partial Tooth-Clipping Of Suckling Pigs: Effects On Neonatal Competition And Facial Injuries, Daniel M. Weary, David Fraser
Partial Tooth-Clipping Of Suckling Pigs: Effects On Neonatal Competition And Facial Injuries, Daniel M. Weary, David Fraser
Farm Animal Husbandry Collection
Piglets are born with fully erupted ‘needle teeth’ which are used in competition for access to teats. Producers often clip these teeth to the gum line soon after birth to avoid any resulting facial lacerations, but this clipping can itself lead to injury or infection. Two experiments investigated the effects on facial injury and piglet performance of the potentially less damaging practice of ‘partial clipping’ whereby only the distal third of the tooth is removed. In Experiment 1, teeth were (1) partially clipped, (2) fully clipped to the gum line, or (3) left intact. All piglets of a litter received …
Asymmetry And Fighting Performance In The Shore Crab Carcinus Maenas, Lynne U. Sneddon, John P. Swaddle
Asymmetry And Fighting Performance In The Shore Crab Carcinus Maenas, Lynne U. Sneddon, John P. Swaddle
Veterinary Science and Medicine Collection
Fluctuating asymmetries (left–right differences in symmetric traits) can be negatively related to fitness parameters in a number of biological systems. Hence, it has been suggested that symmetric individuals should outcompete asymmetric individuals during intraspecific agonistic encounters. However, there is a lack of experimental evidence for such a relationship. We investigated the relationship between trait asymmetry (both directional and fluctuating asymmetry) and the outcome of agonistic encounters among size-matched male shore crabs. Our findings indicate that cheliped (‘weapon claw’) directional asymmetry is not related to the outcome of fights, whereas fluctuating asymmetry in the fifth pereiopod, but not the second pereiopod, …

We previously reported that chimpanzees were unable to optimally select the smaller of two candy arrays in order to receive a larger reward. When Arabic numerals were substituted for the candy arrays, animals who had had prior training with numerical symbols showed an immediate and significant improvement in performance and were able to select reliably the smaller numeric representation in order to obtain a larger reward. Poor performance with candy arrays was interpreted as reflecting a response bias toward the intrinsic incentive and/or perceptual features of the larger array. In contrast, the Arabic numerals represent numerosity symbolically and appear to …

Stream Channel And Vegetation Responses To Late Spring Cattle Grazing, Warren P. Clary
Ecological Impacts of Animal Agriculture Collection
A 10-year riparian grazing study was conducted on a cold, mountain meadow riparian system in central Idaho in response to cattle grazing-salmonid fisheries conflicts. Six pastures were established along Stanley Creek to study the effects on riparian habitat of no grazing, light grazing (20-25% utilization), and medium grazing (35-50%) during late June. Stream channels narrowed, stream width-depth ratios were reduced, and channel bottom embeddedness decreased under all 3 grazing treatments as the area responded to changes from heavier historic grazing use. Streambank stability increased and streamside willow communities (Salix spp. L.) increased in both height and cover under all 3 …

Veterinary Science and Medicine Collection
Galathea intermedia is common, but cryptic, on Clyde maerl deposits where it lives in small groups of mixed sex and age, sharing shelters (typically dead Dosinia shells) to avoid predation. Its appearance is marked by six iridescent blue spots which may play an important role in intra- or interspecific interactions.

Behavioral Interactions And Conflict Among Domestic Dogs, Black-Tailed Prairie Dogs, And People In Boulder, Colorado, Marc Bekoff, Robert W. Ickes
Ethology Collection
Interactions among domestic dogs (Canis familiaris), black-tailed prairie dogs (Cynomys ludovicianus), and people were studied at Dry Creek, Boulder, Colorado. Our objective was to develop a basic understanding of the nature of dog–prairie dog interactions in this recreational area, because this is an issue that has high visibility and over which there is conflict in Boulder: There are those who want dogs to run free regardless of their impact on the behavior and lives of prairie dogs and those who want to protect prairie dogs and have dogs restrained or go elsewhere. We found that dogs clearly influenced the behavior …

Hoarding Of Animals: An Under-Recognized Public Health Problem In A Difficult-To-Study Population, Gary J. Patronek
Passive Cruelty to Animals Collection
Objective. The objective of this study was to better characterize the problem of hoarding, or pathological collecting, of animals.
Methods. The author summarized data from a convenience sample of 54 case reports from 0 animal control agencies and humane societies across the country.
Results. The majority (76%) of hoarders were female, and 46% were 60 years of age or older. About half of the hoarders lived in single-person households. The animals most frequently involved were cats, dogs, farm animals, and birds. The median number of animals per case was 39, but there were four cases of more than 00 animals …

Biomedicine and Animal Models in Research Collection
Animal research has provided important information about many aspects of the pathophysiology of human disease. Well-performed animal studies can determine the potential benefit of many proposed therapeutic interventions, and experimental results from animal studies have served as the basis for many landmark clinical trials. Many animal research models are described in the research literature, and choosing the appropriate model to answer a research question can be a daunting task. Even more challenging is developing a new model when none of the existing systems are relevant to the proposed question. This article was prepared by members of the SAEM Research Committee …

A survey of college courses addressing nonhuman animal ethics and welfare issues indicates that the presence of such courses has increased greatly since a prior survey was done in 1983. This paper provides titles and affiliations of 67 of 89 courses from the current Survey. These courses represent 15 academic fields, and a majority are entirely devoted to animal issues. The fields of animal science and philosophy are proportionally well represented compared with biology and wildlife-related fields. An estimated 5000 or more North American students are now receiving instruction in these issues each year. While the availability of courses in …

Geographic variation in alarm calls of Gunnison's prairie dogs (Cynomys gunnisoni) was analyzed at regional and local scales. Alarm calls in response to a common stimulus (the same human) were recorded at four colonies near Flagstaff, Arizona, and at six sites throughout the southwestern United States. The acoustic structure of calls was analyzed for seven call variables. Regional differences fit the prediction of greater differences with increased geographical separation. Differences between colonies at a local scale were not related to geographical distance, suggesting that local dialects exist within a region. Differences in the level of predation by humans …

Impact Of An Ecological Factor On The Costs Of Resource Acquisition: Fighting And Metabolic Physiology Of Crabs, L. U. Sneddon, F. A. Huntingford, A. C. Taylor
Ethology Collection
- Current game theory models and recent experimental evidence suggests that the strategy an animal adopts in agonistic encounters is determined by individual state. Therefore manipulation of an individual’s state should elicit different behavioural responses. In this paper, mechanisms are examined that underlie state-dependent strategies using Shore Crabs, Carcinus maenas, and how, by altering the environment, behaviour and physiology are affected.
- Fights were staged between pairs of male crabs under normoxic and severely hypoxic (< 15 torr) conditions to determine if the metabolic costs of fighting and resource acquisition are affected by water PO2. After fighting, blood and tissue samples from each crab were taken and analysed for metabolites associated with anaerobiosis (L-lactate, glucose and glycogen).
